Toyota Keyless Remote Programming
Programming a keyless remote transmitter on a Toyota / Lexus vehicle with factory installed keyless entry and alarm. This procedure should work on Toyota's made in the late 90's to the early 2000's, such as the Toyota Solara, Camry, Tacoma, Tundra, Sequoia, Sienna, Highlander and Avalon. This procedure will not work on vehicles with a dealer installed remote, i.e. with a service button / LED on the driver side of the dash-board, such as those with the RS3000 / RS3200 system. Programming the remote involves cycling the locks and ignition. If the vehicle does not enter programming mode or the locks fail to cycle, it could be a worn lock actuator. Try cycling the locks manually instead of using the power lock button switch on the door.

Toyota / Lexus Remote & Immobilizer Key Programming
Here's how to program a Lexus wireless remote transmitter and chipped engine immobilizer key without using Techstream software. Key duplication at a dealership can get expensive, as they charge exorbitant amounts to program a new key. It only takes a few mins to program and you can do it yourself at home. The aftermarket key was purchased from eBay, for about $30. It was then cut at the local Lexus dealership for $20. There are two stages in programming the key: the first to program it to start the car, and the second to program the wireless remote to unlock the doors and trunk. Programming the car involves inserting the key into the ignition and depressing the pedals, then inserting the new key to be programmed. Insure the key matches the FFC ID of the original key before purchasing a replacement. The remote programming involves inserting the key in the ignition, opening the driver's door as well as cycling the door locks. If your door lock actuators are worn out, the locks can be manually cycled. The vehicle demonstrated is a 2000 Lexus GS300. Procedure should be the same for all 1998-2005 Lexus GS300 GS400 and GS430.

How an ABS Motor Works
A brief teardown and look inside an ABS pump. The Anti-lock Braking system in your car prevents your wheels from locking up during braking. Preventing a skid is key to maintaining steering control and stability during a maneuver. Wheel speed sensors feed an ABS computer to monitor if your wheels are skidding during braking. When the brake pedal is depressed, brake fluid flows through the master cylinder to the ABS pump and out to the wheels. If the ABS computer detects the car is skidding, it activates a relay in the ABS motor, temporarily releasing brake pressure up to 15 times per second, preventing a skid. Opening up the ABS unit reveals a heavy duty DC motor that is responsible for building brake pressure and 12 solenoids, three for each wheel. ABS wheel speed sensors are a magnetic sensor that function similar to a hall effect sensor. It responds to changes in the magnetic field from the splines in the driveshaft or hub, which generate a voltage that the computer can read. The ABS system also functions as part of the vehicle stability control, brake assist, pre-collision braking, traction control and active cruise control among other safety features in modern cars.

How a Catalytic Converter Works
Here's what's inside a Catalytic Converter and how it works on your car. The catalytic converter is located after the exhaust manifold, but before the resonator. Its duty is to convert harmful exhaust gases into less toxic gasses. The catalyst inside the converter is made of platinum, rhodium, palladium and sometimes gold. These precious metals are very expensive, thus making recovery of used catalytic converters a very viable business. Replacement catalytic converters are also very expensive. The catalytic converter forms part of a closed loop control system, whereby the ECU targets the air to fuel ratio for optimal combustion and efficiency of the catalytic converter. Often there is a rear oxygen sensor after a catalytic converter that keeps eyes on the oxygen levels coming out, to ensure it is working efficiently. Running the vehicle too rich can caused too much unburned fuels to go inside the catalytic converter, causing it to combust and overheat. The catalyst cannot convert gases anymore and looses its effectiveness. That's why its important to check out the check engine lights on your car to ensure it doesn't damage anything down the road. This catalytic converter was removed from a 2001 Toyota Corolla. Related video: How a Muffler Works: https://www.youtube.com/watch?v=Dw3qTobtzFg

How an Airbag Sensor Works
Here's a tear down on how an airbag sensor works. An airbag sensor is responsible for detecting sudden deceleration in a collision. It sends a signal to the airbag computer which use the vehicle speed, yaw, seat belt and ECU to determine if an airbag should deploy in a crash. There's two types of mechanical airbag sensors, the cam type and ball and tube style. The ball and tube style of airbag sensor consists of a ball, in a tube, held to one side by a magnet. When the sensor experiences shock, the ball is dislodged from the magnet and strikes the terminals of a switch, sending a signal to the central SRS computer. The cam type of airbag sensor, explained in this video, uses the momentum of a pivoting cam on its own axis of rotation to strike a switch terminal completing the circuit. A diagnostic resistor is wired in parallel in all sensors. This is for the SRS computer to perform a self check at startup to ensure all sensors are present and operational. This video explains the differences between sensor types and shows how to access and replace your sensor on a Toyota Camry. Procedure will be very similar for other vehicles, as the sensors are usually bolted to the radiator cradle around the headlight area. It also goes into a tear down of an actual airbag sensor, where you can see the little cam mechanism and switch strike terminals. The latest high tech airbag sensors use Micro-electrical Mechanical systems, or MEMs to sense acceleration. Since they're machined or etched into silicon directly, the sensor footprint can be much smaller, in the range of micro-meters.

Honda Remote Key Programming
Here's how to program a new remote on your Honda or Acura. This procedure was demonstrated on a 2003-2007 Honda Accord. The procedure should be similar for the Pilot, CR-V, Civic and Element. If your keyless remote is busted, or you want a second set of keys, why pay the dealership to program a remote for you when you can do it yourself and save money? The procedure is quite easy and is as follows: 1. Insert your master key into the ignition, then it on, press the lock or unlock button once, then turn it back off. 2. Repeat step 1 two more times, without taking the key out of the ignition. 3. Turn the key to the on position for the fourth time, and press the lock button. You'll hear the locks cycle, indicating its in programming mode. 4. Press lock or unlock buttons on your first remote, followed by subsequent remotes that you want to program. The locks will cycle indicating it has accepted the remote. 5. Turn the key off and pull it out of the ignition. Test each remote to see if it works! Notes: Make sure you have all your remotes present when programming, as it will over ride your previously programmed remotes. The system can store a maximum of 4 remote keys. This procedure not to be confused with engine immobilizer programming, which is needed for a new key to start the engine. For that you'll need Honda HDS, a PCM code or a dealership / locksmith to program it for you. New keys can be found on eBay. Look for keys with OEM electronics. A fresh key blade can also be bought on eBay, and the electronics can be transferred over. The keys in this video were sourced from junkyard cars.

How to Replace a Honda VTEC Solenoid Gasket
Here's how to replace a leaking or clogged VTEC solenoid and gasket on the 2.4L 4 cylinder K24 engine. Leaking a leaking VTEC gasket or clogged/malfunctioning VTEC actuator are a common problem on older Honda's. The VTEC solenoid mounts to the engine head, and allows the flow of oil into small passages that change the camshaft profiles, causing the engine to perform faster. This is not to be confused with the VTC solenoid, which advances or retards the variable valve timing gear to change engine timing. A video on VTC solenoid replacement can be found here: https://www.youtube.com/watch?v=YYKikGysXqE If your Honda is leaking oil down the passenger side of the engine, the most probable cause is a leaking VTEC solenoid. Oil will drip from the top, down over the oil filter and the side of the drain pan, and in some cases onto the subframe. Significant oil loss can be observed, along with a P1259 VTEC malfunction code. This tutorial demonstrates how to replace the VTEC solenoid and gasket. The gasket itself has a strainer that can sometimes get clogged. This procedure will be applicable to the Acura TSX, Honda Accord, Honda CR-V and Element. Three 10mm bolts secure the VTEC solenoid to the back of the engine, toward the firewall. It can be accessed from both the top or bottom of the engine. Have a catch pan ready to drain access oil once the bolts are removed. The oil pressure switch is also part of the solenoid assembly. Clean the mating surfaces thoroughly, before reinstalling the gasket dry. Torque the three 10mm bolts to 104 in-lb. Top off the engine oil and start the vehicle. Once the engine is warm, check for leaks.

How an A/C Compressor Works
Here's what's inside of an automotive air condition compressor and how it works to cool the interior of your car. The A/C compressor is powered by the crank pulley on a car's engine. The A/C compressor is responsible for compressing gaseous refridgerant that exists the evaporator. The compressed refridgerant stays in a gaseous state since liquids cannot be compressed. The refridgerant moves through the condensor where its turned into a liquid, run through a drier and then back to the evaporator core. The compressor is the heart of the system that keeps the refridgerant changing its state by adding energy to the system. This energy is then used to cool the cabin. For more background on a car's HVAC system, see my HVAC system teardown video here: https://www.youtube.com/watch?v=04MlTepEIz4 The inside of an A/C compressor consists of 10 chambers that house 5 pistons (each are horizontally opposed). The pistons move back and forth by means of a slanted plate (called a swash plate) that moves eccentric to the axis of the A/C compressor. The movement of the pistons are what compress the refridgerant and keep the flow moving through the system. The flow is controlled by reed valves, which are gasket like materials with valves on them that move when pressure is applied. This regulates flow and direction of gaseous refridgerant An A/C compressor can use a lot of the engine's energy, hence it does not always activate while the engine is running. To disconnect the A/C, an electromagnetic clutch is used to pull the clutch pulley inward, toward the idler pull that the vehicle's accessory belt has wound around. The free spinning idler now latches onto the armature, which turns the internals inside the A/C compressor. Typical failure points on an A/C compressor include a worn clutch, too large of an air gap between the friction material on the clutch and idler, a worn idler pulley, leaking gaskets and O-rings, a defective electromagnet or relay, or a seized clutch.

Why do Cars Burn Oil?
Ever wonder where your car's engine oil disappears to? If its not leaking oil, its burning it! In this video, the two main reasons why internal combustion engines burn oil are presented and discussed. The piston crank bearing, connecting rod wrist pin, cylinder walls and valve train are all coated with oil through the engine's lubrication system. Learn more on that in my engine lubrication system video here: https://www.youtube.com/watch?v=IMkxjd-YZAI The first reason cars burn oil is because of worn piston rings, a stuck oil control ring, or clogged piston head. This can likely be attributed to carbon and sludge buildup blocking the oil return holes drilled into the piston head. Sludge and carbon builds up when the petroleum in the engine oil breaks down at high temperature - an engine design defect. The oil has no where to drain, and gets drawn onto the combustion side of the piston where its burned and exits the exhaust. The second reason cars burn oil is through the valve stem seals. The valves are situated between the well-lubricated cylinder head and combustion chamber down below. When the valve stem seals age, they get dry and crack and may leak oil. Typically overnight, oil pools up around the valve and drips down on to the piston. The next morning upon startup, a huge plume of blue smoke is sighted out of the tail pipe, which is the oil burning away. Some engines are more susceptible to oil burning than others. The only way to cure oil burning past the rings are to drill holes in the piston heads and change the rings, which requires a full engine tear down. Changing the valve stem seals are still labor intensive, as it requires removal of the engine head and valves. Here's how an engine works, with disassembly: https://www.youtube.com/watch?v=bxcgOV3swhQ The engine components demonstrated in this video came out of a 2001 Toyota Corolla. It had 204,000 km and burned some oil through the piston rings. The piston ring problem is common on the Corolla, Camry, Rav4, Scion tC, Matrix and Highlander with the 1ZZ-FE and 2AZ-FE engines. Here's an excellent video on rebuilding the 1ZZ-FE engine: https://www.youtube.com/watch?v=A595LR4SQpI Check out the speedkar99 Facebook page: https://www.facebook.com/speedkar9/ Follow me on Instagram: https://www.instagram.com/speedkar9/ Subscribe for more videos just like this: https://www.youtube.com/subscription_center?add_user=speedkar99

How a Hydraulic Steering Rack Works
Here's how a hydraulic steering rack works to turn the wheels on your car. Hydraulic steering has been used for decades to provide assist to drivers turning the wheels of especially heavy vehicles. Fluid is pressurized by a hydraulic pump and is sent to the rotary valve via the high pressure hose. The rotary valve has a small torsion bar, which connects its input shaft (from the steering column) to the output shaft (the pinion gear). The torsion bar twists slightly, opening up a small passageway for fluid to escape and be lead out to the piston. Depending on the direction, the fluid is pushed into the opposite side of the cylinder housing, pushing the piston. The piston is connected to the rack, which connects the tie rods and hence the wheels at the steering knuckle. Once there is no more torque on the steering wheel, the torsion bar resumes its rest position, and fluid is fed back to the reservoir to be recycled again at the pump. Mechanically, the pinion links the steering wheel to the rack, to provide a manual method of steering as a fail safe. Hydraulic power steering setups are rather inefficent, which of recently has given way to the trend of electric power steering, where an

How a Brake Booster and Master Cylinder Work
Here's how a brake booster and master cylinder work to stop your vehicle with the press of your brake pedal. Stopping a heavy, 2000+ lb car is no easy task. It takes a lot of force to press up against the discs and drums on each wheel to stop a car quickly. The hydraulics of brakes is quite simple. A primary piston (known as the master cylinder) pushes fluid into hydraulic lines that get fed out to the wheels. The piston inside the caliper (or wheel cylinder inside the drum) will expand with the fluid, causing it to glide up against the disc (or drum), slowing the wheel. The brake booster was developed to sit in between the master cylinder and driver's pedal, to make it easier for it to press the pedal. While the master cylinder's diameter is already smaller than that of the caliper pistons, the force required to compress it is still great. The brake booster works on the principle of vacuum differentials to aid in pushing the master cylinder. On one side, vacuum is sucked from the engine's intake. At idle, a valve in the diaphragm allows vacuum to be passed through the diaphragm, so that vacuum balances both sides. When you depress the brakes, that valve moves, sealing off the vacuum side, while allowing filtered atmospheric air to enter the booster from the brake pedal side. This creates a pressure differential between the diaphragm, which helps to force the piston in the master cylinder to compress. A giant return spring brings the diaphragm back to its rest position when the brake pedal is released. The master cylinder consists of two small pistons in series. Each piston routes to two diagonally opposite wheels, for redundancy in case one springs a leak or the seal is compromised. Reserve brake fluid is contained in a reservoir above the master cylinder and is sucked into the piston assembly when the brake pedal is pushed. Periodic brake flushes are required because brake fluid is hydroscopic and will absorb moisture and loose its effectiveness over time. Furthermore brake fluid will wear down with heat, and may become contaminated.

How Manual Windows Work
Here's how crank windows work on your old school economy car! The manually operated windows came on many entry level cars of the past decade. It represented a cost-effective solution to winding down your windows, without the added complication of electronics, motors or gears. The window regulator is quite simply a 4 bar mechanism, with a pivot in the middle, and two sliders on either end that act like a collapsing scissor. At the crank, a small gear rotates a 1/4 of a sun dial gear, giving a torque multiplication. This makes it easy for a short rotation of the crank to lift such a heavy window. The dial gear is attached to the main arm that leads up to support the glass. A torsional spring helps to wind the window up against the force of gravity. It loads itself when winding the window down, giving resistance so the window doesn't just drop. The door skin on this 2001 Toyota Corolla was cut open to demonstrate how the window mechanism works from the outside of the vehicle.

DIY Bumper Crack Repair
Here's how to repair a crack in a plastic bumper. Cracked bumpers are common on many vehicles that frequent shopping malls drive on rural roads. Often times a replacement is not warranted due to high cost or low quality replacements. This video demonstrates how you can fix your cracked bumper by yourself at home, with supplies you can get from any auto-parts store. First, a V-groove is grinded into the back of the crack to increase the surface area for the epoxy adhesion. The crack is then sanded and cleaned. The top of the crack was secured with a clamp and the front of the crack was held together with tape. JB-Weld Plastic Bonder was then used to fill in the crack from behind. Drywall tape was used as a reinforcement and the setup was allowed to cure overnight. After the 2-part epoxy is dried, it will be rock hard. From the front, the crack should now be much less visible if it was aligned properly. Sand the front of the bumper around the damaged area. Use plastic auto-body filler to fill in the cracks, and progressively sand the filler off before applying primer. Use some rubbing alcohol, paint thinner or acetone to clean the surface before applying primer. The primer was then wetsanded before paint was applied. The paint was ordered in a spray can from CarQuest and mixed according to the paint code. The color match is very close, just slightly darker due to the 12 year old oxidized paint, and there is a decent pearl that shines back in the sunlight. Two thin layers are applied then allowed to dry for a few hours before handling. The bumper can then be replaced on the vehicle and fasteners reattached. Wait a few days for the paint to fully cure before applying polish and wax. Now stand back and enjoy your repaired bumper. The whole process shouldn't take more than a day if you factor in drying time. This video is an excellent tutorial to follow: https://www.youtube.com/watch?v=EqzJ2VMrgQ0 Check out the speedkar99 Facebook page: https://www.facebook.com/speedkar9/ Follow me on Instagram: https://www.instagram.com/speedkar9/ Subscribe for more videos just like this: https://www.youtube.com/subscription_center?add_user=speedkar99

How to Replace a Honda Thermostat
Here's how to replace a thermostat on a 4 cylinder Honda 2.4L engine. The thermostat is responsible for controlling the flow of the engine coolant as it circulates through the engine block. When the engine is cold, coolant does not flow. Once the engine warms up, the thermostat opens, circulating coolant to keep it at optimum operating temperature. Sometimes the thermostat fails to open or close, causing the engine to run cold or overheat. The thermostat can also be replaced as a preventative measure when the engine coolant is drained, such as when changing a radiator or water pump. Never work on the cooling system when the engine is hot. Drain the radiator through the bottom petcock valve and dispose of the coolant safely. The thermostat is located on the engine block facing the front of the vehicle, under the intake plenum. There's three 10mm bolts that need to be removed, along with the clip for the lower radiator hose. Have a catch can located underneath the thermostat to catch remaining coolant in the block when the thermostat is removed. Replace the gasket and clean all mating surfaces with brake cleaner. Replace the 10mm bolts and torque to 86 in-lbs using a torque wrench to avoid leaks. Replace the radiator hose. Refill the cooling system with a 50/50 mixture of phosphate and silicate free Honda compatible engine coolant. Leave the radiator cap off and turn on the heater to cycle all the air through the system until the fans turn on and bubbles stop appearing. This video was demonstrated on a 2004 Honda Accord 4 Cylinder. Procedure is the same for 2003-2012 Honda Accord and similar for the CR-V, Element, Civic, Acura RSX, and CSX.

How a Car's HVAC System Works
Here's how an automotive heat, ventilation and air conditioning system works. The HVAC system in a car is situated under the dashboard and controls the heat and cooling systems, as well as the defroster. The AC system consists of the compressor, condenser, drier, evaporator core and expansion valve, the latter two of which are under the dash and are demonstrated in this video. The heating system consists of the engine, water pump, and a heater core, which is under the dash. The blower motor, usually situated behind the glove box will blow air from outside or recirculate air from inside the cabin. Air flows past the evaporator core where it is cooled, before heading to the HVAC mixer. The mixer determines if the air is to be heated or left cold. It also directs air to your face, feet or the defroster. This is done by mechanical flaps inside the housing. This video goes into details of the thermostatic expansion valve, evaporator core, recirculate actuator, blower motor, temperature sensor, blower resistor, flap actuators and the heater core. Dashboard removal is necessary in order to access any of these components.

OEM vs Aftermarket Ball Joints
Here's a break down comparison on how a ball joint works, and the differences between the OEM and aftermarket design. A ball joint is a suspension component that is used where three-axis rotation is required. Normally it would connect the control arms to the steering knuckle of the car. On a McPherson front suspension setup, there is one lower ball joint, while on a double wishbone front suspension setup, there's an upper and lower ball joint. As a result, ball joints can wear down over time and have to be replaced. Failure to replace it can lead to the suspension dismembering itself, and the wheel to come apart from the vehicle. This video opens up an OEM ball joint and an aftermarket and takes a look at the differences in components inside. The OEM ball joints typically use a metal ball stud with a plastic bearing, while the aftermarket ball joint use a metal stud with a sintered metal bearing. However, the OEM ball joints are typically sealed, non serviceable components, while the aftermarket ball joints come with a grease fitting. A sintered metal bearing must be periodically greased for it to outlast an OEM ball joint. Differences in the material, construction, dimensions, coating and design are also discussed in this comparison.

Lower Control Arm Replacement Honda Accord
Here's how to replace the lower control arm on a 2003-2007 Gen 7 Honda Accord. Many older Honda's use a double wishbone suspension. The setup includes an upper wishbone, or control arm, a lower control arm, steering knuckle and a coil-over strut all held together at the upper and lower ball joints. Over time, the control arm bushings could crack due to wear. This could cause problems with alignment, poor handling, excessive or abnormal tire wear or vibrations on the highway. Replacing the lower control arm on a Honda requires the removal of the suspension fork, lower ball joint, stabilizer linkage, and two bolts attaching it to the subframe. The OEM stabilizer linkage is most likely rusted and worn and will require you to cut it off and replace it with a new one. The rear control arm bushing bolt sometimes get seized in the sleeve of the bushing and can't be removed. It will have to be cut off from the subframe and the bushing be pressed out, and a new bolt installed. A ball joint separator is required to pop the ball stud cone free from the taper on the lower control arm. It is recommended to use a scissor jack to support the steering knuckle assembly so the upper ball joint does not take all the weight. Take care not to pull the CV axle out too far when maneuvering the steering knuckle free from the ball joint, as that can cause the CV tripod to slip out. If this happens, simply jerk and rotate the axle - hub assembly until it slips back into place. The use of air tools is not necessary but makes the job a lot faster. Use a breaker bar to break bushing bolts free because the rubber will just absorb the impact and won't budge. Once the control arm is free, take it to a shop to have them press out the old bushings and press in new ones. New control arms with bushings preloaded are also available to make the job much easier.

How an A/C Dryer and Condenser Works
Here's how the condenser and dryer work as part of the air conditioning system in your car. The air conditioning system works to cool and remove moisture from the cabin year round. Gaseous Refrigerant circulates from the compressor, before moving on to the condenser and dryer and then out to the expansion valve in the evaporator core, before being recirculated through the system again. The A/C dryer is responsible for removing moisture from the refrigerant, filtering dirt and providing a storage area for excess refrigerant that's built up in the low demand times of the cycle. The A/C condenser cools the compressed gas refrigerant, turning it into a liquid. This is an exothermic reaction, and therefore the condenser must ventilate the excess heat. This is why condensers are located in the front of the vehicles, near the radiator. In this video, a dryer and condenser from a 2001 Toyota Corolla are removed and cut apart to see what's inside and explain how it works. The dryer works by having two filters that surround desiccant beads that absorb moisture. A condenser is similar to a radiator, having aluminum fins around narrow tubes through which the refrigerant is passed through.

P1349 Oil Control Valve Replacement  - Lexus IS300 / GS300
Here's how to diagnose and replace the VVT oil control valve and filter in response to engine codes P1349 and P1656. This procedure was demonstrated on a 2000 Lexus GS300 and is applicable to the Lexus IS300, GS300, SC300 and Toyota Supra with the 2ZJ VVT inline 6 engine. The oil control valve is responsible for controlling the amount of oil entering the variable valve timing gear. The computer actuates the solenoid inside the OCV to advance or retard the timing depending on engine input. Sometimes the inline filter inside oil line leading to the OCV can get clogged and throw a P1349 and/or P1656 check engine light code. The valve itself could also accrue particles over time and not fully open or close when required and cause intermittent rough idle due to retarded timing. Replacing the valve is very simple, requiring the removal of the timing belt cover and one 10mm bolt. Replacing the filter involves removing the 22mm banjo bolt and a 10mm bolt that holds the line to the engine. The Banjo bolt has two crush washers that should be replaced if opened. A Dorman 917288 Variable Timing Solenoid was used instead of Toyota OEM part number 15330-46011, Valve assembly, camshaft timing oil control.

Sway Bar Link Replacement - Toyota /  Lexus
Here's how to replace a sway bar linkage on a Toyota or Lexus vehicle. Procedure is similar for other domestic and import vehicles as well. The stabilizer link ties the strut to the stabilizer bar, which acts as a torsion beam to reduce body roll during cornering. On many older Toyota and Lexus vehicles, a worn stabilizer link is a common cause of rear suspension clunks when you drive over bumps. The link is connected via a small ball joint and a boot. If the boot is ripped, or after high mileage, dirt and debris can get in and degrade the ball joint, causing it to be loose. While it''s not a direct safety issue if the bar fails, its characteristic clunking will require addressing if you desire sane ride quality. The ball joint on the sway bar is held by a 14mm nut and a shaft to be held with a hex key. It's common for the hex key hole to strip out, leaving you to either use vise grips to grip the shaft of the ball joint stud while removing the nut or cut the link off altogether. The replacement stabilizer bar link is made in China for a Canadian company, Mevotech, model MK90345. It will fit Lexus ES300, ES330 and ES350, RX330, RX350, ES300H, RX400H as well as Toyota Camry, Highlander, Avalon, Venza and Solara. Zerk fittings are included with the link and are to be installed and greased when put into service. Use a lithium or high temperature wheel bearing grease in a grease gun. The Mevotech stabilizer linkage does not have a hex hole in the stud, instead it uses two nuts to be tightened against each other with wrenches, avoiding the stripping problem of the OEM link units. Be sure both wheels are off the ground when replacing so no tension is on the stabilizer link or bar.

How a Power Steering Pump Works
Here's how a power steering pump works to provide pressure to the power steering rack on your car. A power steering pump is essentially a vane pump. Inside, a rotor with translating vanes rotates inside an eccentric cam housing. The vanes are flung toward the outside of the cam housing on either side where pockets are formed. As the rotor rotates, the pockets become smaller as the vanes retract. This creates a high pressure zone on one end, and a low pressure zone on the other end, driving the fluid flow. Power steering pumps are self regulating, in that they can regulate the flow of the fluid coming out as the engine RPM increases. Inside the flow control valve consists of a ball and a spring. Excess fluid is pumped pass the spring and back out to the low pressure inlet port. That's how the steering effort is not over-boosted at higher speeds.

How a Muffler Works
Here's what the inside of a muffler looks like and how it works. A muffler is used near the end of the exhaust system on a vehicle to reduce the noise emitted by the engine. The noise comes from the combustion chamber, and travels through the exhaust stream. The muffler has a series of perforated tubes, baffles and a trap door that redirect exhaust gases. As the gases travel, sound waves are either absorbed, or reflected and destructively interfered, cancelling them out. The exhaust gas continues to flow around in the muffler and out the tail pipe. However, most mufflers pose as a restriction for an internal combustion engine, because the exhaust gases have to travel around, back in a reverse direction and then out the tail pipe. This is known as reverse flow or turbo style muffler. Many mufflers are accompanied upstream by a resonator, that reduces certain frequencies of sound in the exhaust stream before it enters the muffler. On the outside, it looks like a small tube increasing to a large diameter tube, and then back down to exhaust pipe diameter. Mufflers work on the principle of destructive interference and absorption. The walls of the muffler are made of two layers of stainless steel, which help reduce vibration and absorb sound. Some mufflers have a fiberglass material around the perforated tubes to help absorb sound. Destructive interference occurs when a sound wave is reflected off a surface and interferes with the inbound sound wave. The high amplitudes interference with the low amplitudes, and the net amplitude becomes zero. Baffles are strategically distanced to cancel out certain frequencies. The muffler illustrated in this video was from a 2001 Toyota Corolla. It features a spring loaded passive exhaust flap. The flap opens once pressure is built at higher RPM's, allowing the majority of exhaust gases to enter into the third and final chamber, before exiting the tail pipe.

Timing Belt / Waterpump Replacement: Toyota & Lexus V6
Step by step DIY Video on how to replace the timing belt, waterpump, camshaft and crankshaft seals, idler pulleys and tensioner on a Toyota or Lexus with a V6 engine. Procedure is the same for all 1994-2006 1MZ-FE (3.0L) and 3MZ-FE (3.3L) engines, with the newer engines differing only in the timing belt tensioner bolts. Procedure is straight forward starting with the removal of the dog bone mount, engine support bracket, alternator and power steering belts, crank pulley (harmonic balancer) and timing belt covers. Once access to the timing belt is achieved, the tensioner is released so the belt can be removed. The camshafts should be removed to get to the waterpump, otherwise two studs running through the waterpump have to be removed. Special tools required are an impact wrench and air ratchet (not mandatory), a seal puller, a pulley puller, torque wrench, and a crankshaft and camshaft holding tool. This job should take 4 hours for a DIY'er with moderate mechanical aptitude. The Aisin timing belt kit with waterpump from RockAuto was used. After the removal of the cam and crank bolts, the hardest part of this job was dealing with the rear camshaft seal and aligning it with the marks on the timing belt. Access is tight near the fender wall and removing the power steering fluid line and reservoir is recommended.

Alternator / Power Steering Belt Replacement: Toyota Lexus V6
Here's how to replace the alternator and power steering belts on a Toyota or Lexus with a V6 engine. The serpentine belts are responsible for driving accessories off of the crank of the engine. In the Toyota V6 engines, they drive the alternator and A/C compressor on one belt, and the power steering pump on the secondary belt. Replacing the belts is a good idea if they are worn, cracked or are squealing on cold starts. Belt failure can lead to sudden loss of steering, a discharged battery or an ineffective A/C system. The procedure is simple, and you don't need air tools. A ratchet set with 10, 12 and 14 mm sockets will work. A breaker bar with a 22mm socket is recommended to turn the crank pulley clockwise to aid in slipping the new belt on. You'll also need your tire iron, jack, jack stands and a crow-bar or flat screwdriver to tension the power steering belt. A visual diagram is provided in the beginning of the video to aid where the bolts are located on the engine. The alternator belt uses a pinch bolt and a long tension bolt, in addition to its pivot bolt. The power steering bolt has a tension bolt and a pinch bolt that slides on a track. Tensioning the power steering belt can be difficult since the position of the pump, determined by the position if your pry bar, determines the tension. This video showed the procedure on a 2005 Lexus ES330 with the 3.3L 3MZ-FE V6 engine. The procedure is the same for 1MZ-FE (3.0L) and 3MZ-FE (3.3L) Toyota Camry V6, Solara, Sienna, Highlander, Avalon and Lexus ES300, RX300 and RX330.

How Drum Brakes Work
Here's how drum brakes work to stop your car. Drum brakes are typically found on the rear of most economy cars. They are economical, however don't offer the stopping power that disc brakes do. They consist of a shoe, which carries the pad material and a drum, to which the shoes internally contact to slow the wheel. The shoes are controlled by return springs and are activated by a wheel cylinder. The wheel cylinder is essentially a piston that pushes both shoes outward near the top of the assembly. The parking brake cable also uses the drum brake components to activate. Instead of a wheel cylinder, a manual cable pulls on a secondary lever that will push out the shoes. In this video, the rear drum brakes from a 2001 Toyota Corolla is taken apart to demonstrate how each component fits and function in the assembly.

Toyota Techstream Software Demonstration
Toyota Techstream is the software used by dealerships for vehicle diagnostics and to personalize settings on your Toyota, Lexus or Scion vehicle. The software connects to a car via a Mini VCI cable through the OBDII port. Cheap cables, available on eBay, emulate a serial port to which Techstream software communicates to your car's CAN bus. The software allows you to access vehicle settings, such as door locks, transmitter, engine immobilizer programming, power window, interior illumination as well as security and headlights. It is also used to read specific ECU codes from the engine computer, ABS/TRAC/VSC, SRS Airbag and occupant detection systems. Built in diagnostic tools allow you to perform tests on failing parts to determine what is at fault. Additionally, having access to techstream allows you to program your own chipped keys and wireless remotes. This tutorial quickly goes through the settings and monitors available in Techstream for a Lexus ES330. It will be similar for many other Toyota, Lexus and Scion vehicles that use the CAN bus made after ~ 2002. Here are the installation instructions: http://www.ft86club.com/forums/showthread.php?t=73034 http://www.ft86club.com/forums/showthread.php?t=35530 The cable was purchased from eBay.

How a Torque Converter Works
Here's how a the torque converter works in vehicles with an automatic transmission. The torque converter is responsible for transferring torque from the engine to the transmission. It has three main functions: 1. Allow slippage: when the wheels are stopped, the engine can remain running. 2. Torque multiplication: the stator provides multiplication at low engine RPM's to help the car get off the line easier. 3. Converter lockup: To lock the input and outputs to provide a 1:1 ratio with no loss or slip. The converter consists of four main components: 1. The housing, or pump. This is responsible for throwing transmission fluid up through its vanes through centrifugal force toward the outside edge of the converter. This is the input and rotates with the engine. 2. The turbine. This picks up the fluid flung by the pump and changes its direction of flow, causing a torque. The torque causes the turbine to rotate, and is the output of the converter, which connects to the input shaft of the transmission to turn the gears. 3. The stator. This redirects fluid flow once again to allow the pump to recirculate the fluid. It also contains a one way clutch and is responsible for torque multiplication at lower RPM's. 4. The lockup clutch. This locks the input and output of the converter together for zero loss while at cruising speed. The torque converter was removed and cut open for demonstration from a 2001 Toyota Corolla with the 4 speed automatic transmission.

Rear Strut Replacement Toyota Lexus
How to replace the rear struts on a Toyota or Lexus sedan. Procedure is similar for the Lexus ES300, ES330 and ES350, Toyota Camry, Solara, Avalon, Corolla and maybe the Yaris. The rear MacPherson struts are attached to the knuckle via two 19mm bolts. The stabilizer linkage, ABS wire and brake line need to be disconnected from the strut to free it at the bottom. To access the three 12mm bolts holding the strut to the body, the rear seat must be removed. The bottom cushion pulls up, while the seat back is bolted in with 4 12mm bolts. Removing the side panels and deck tray is not required. Having a 12mm ratcheting wrench helps with accessing the strut bolts. Air tools are not required but make the job a lot easier.

How an Auto Dimming Rear View Mirror Works
Here's a break down on how an auto-dimming electro-chromatic rear view mirror works. Drivers often face glare from vehicles behind when driving at night. Traditional mirrors use a flip tab to deflect the glare up and away from the driver's sight-lines. However most cars today come with auto-dimming rear view mirrors, which automatically dim the mirrors reducing glare as the conditions warrant. Auto-dimming mirrors rely on the principal of electro-chromism. It consists of 5 materials sandwiched between a clear glass and a mirror. The two outer materials are conductors, followed by an ion storage layer, an electrolyte, and the electrochromic layer. When a voltage is applied to the assembly a chemical reaction occurs whereby the ions migrate across the electrolyte into the electro-chromic layer causing it to darken. This significantly reduces the light that can pass through the electrochromic layer to be reflected by the mirror back to the driver. Auto dimming mirrors have two light sensors, one in front to detect ambient light, and one in the back to detect glare. They feed into a control circuit which applies a low voltage to the electro-chromic glass accordingly. Gentex was one of the first companies to pioneer and mass produce this technology to the automotive industry. Once a luxury item, auto-dimming rear view mirrors are common place on many cars today. Mirror shown in the video was from a Toyota Solara but is universally applicable to many other vehicles.

How an Ignition Coil Works
Here's how an ignition coil works on car to fire the spark plug in the combustion chamber. Most modern vehicles use a coil-over-plug ignition design so the computer can individually program them to maximize efficiency or power. Spark plugs fire inside the ignition coil to ignite fuel and burn the mixture, pushing the piston down to turn the crank shaft. To fire the spark plug, a rapid high voltage is required for reliable clean combustion. The ignition coil is responsible for increasing the voltage from the car's 12V power system to the thousands of volts needed to fire a spark plug. The ignition coil is essentially a step up transformer, taking a smaller primary winding wrapped around a more dense secondary coil winding and an iron core. When the circuit switch is opened, the change in the electromagnetic field causes a huge voltage spike that fires across the spark plug tip. In this video, an ignition coil from a 2001 Toyota Corolla is cut open to show the various layers and components inside, including the shielding, primary and secondary coil windings, insulators as well as the iron core.

How to Remove an Engine
Here's how to disassemble and remove an engine and transmission from a Toyota Corolla. Removing the engine from most transversely mounted, 4 cylinder cars are quite similar. In my case, I opted to disassemble major components off of the engine before removing the engine and transmission as an assembly, including water pump, alternator, starter, AC compressor, power steering pump, air intake, throttle body, radiator, AC condenser and exhaust manifold. This allows a lot more room in the engine bay for removal. if your doing a straight engine swap, the removal of these components is not necessary. Once the above mentioned components are removed, there are 4 engine mounts that hold the engine/tranny to the car body. The front and rear mounts are bushings with a thru bolt. They are secured underneath the subframe by 3-4 bolts. The driver side tranny mount is also a thru bolt. However since the tranny is being lifted up, the mount must be removed from the inner fender. The passenger side engine mount is a vertically mounted bushing, and is typically left for last. Strapping the engine was done with a thick heavy chain, around the engine. Seat belts were used across the driver and passenger side mounts for balance. A shop crane was used to hoist the engine and transmission up over the car, and then the car was rolled back. 6 bolts hold the engine to the transmission at the bell housing. Once separated, the torque converter is exposed. It can then be unbolted from the flywheel beneath the access plate under the engine block. The flywheel is then unbolted, and the engine mounted to an engine stand using the engine mount bolts. This process was demonstrated on a 2001 Toyota Corolla with a 1ZZ-FE vvti engine.

How a Cruise Control Actuator Works
Here's how a cruise control actuator works on a car with a drive by cable throttle body. Cruise control is used to maintain a constant speed without input from the driver's foot via the gas pedal. This can be a savior on long distance trips, reducing driver fatigue and increasing fuel economy. On a drive by cable car, the actuator is situated between the gas pedal cable and the throttle body. It has two plates that move independently, with an electronic motor that can over ride its output to the throttle. Inside the actuator is a small circuit board with two limit switches, a few diodes and capacitor. The limit switches tell the actuator the start and stop positions of the motor. Further inside, there are two motors, one solenoid type that acts as an electronic clutch, and the second motor actually turns the cable trolley via a spiral gear-train. The electronic clutch engages the cruise control motor to the throttle body plate in the actuator. Its essentially an electromagnet that attracts a free spinning gear (attached to the drive motor) to lock up into the spindle when engaged. The amount that the actuator rotates is controlled ultimately by the ECU, based on the driver's set speed and the vehicle's current speed. It is a closed loop control system that is constantly monitoring vehicle speed for any slight changes from external sources, such as a hill or a headwind, and adjusting the throttle position accordingly. Replacing a cruise control actuator is fairly straight forward, with two cable connections, a 4 pin electronic connector and 4 Phillips screws attaching it to its mounting bracket. On drive by cable cars, the throttle is already driven directly by an electric motor. The ECU controls the throttle via this motor for both normal throttle acceleration and cruise control.

How an Airbag Works - Takata Recall Explained
Here's an inside tear down of the internal components of an airbag, and how it works to save you in an accident. An airbag works on the principle of a rapidly expanding gas that fills a balloon of air to cushion the impact of the occupant's head during a collision. The reactive compound in the inflator is sodium azide, which decomposes into nitrogen gas and sodium. This explosion fills the airbag within milliseconds, and the deflates allowing the driver to regain control of the vehicle. The Takata airbag recall was issued to vehicles with defective airbag inflators that would inflate with too much force. This could cause shrapnel to explode into the occupant's face and cause injury or death. In this video, a Honda airbag is taken apart as a demonstration to show the internal components of the airbag, including the airbag cover, the airbag balloon, the horn switch, airbag inflator and tamper proof electrical connectors. Warning: Never take apart an airbag that has not been exploded. Any static or electrical current can set off the unstable sodium azide compound, causing it to explode.

Power Steering Fluid Flush
How to flush the power steering fluid on a Toyota, Lexus or Scion vehicle with hydraulic power steering assist. This will work with many other brand vehicles that have hydraulic power steering and an easily accessible reservoir. Power steering fluid wears out over time and can lose its lubricating properties. While many service manuals may not give a specific time to change this fluid, many power steering rack failures can be attributed to dirty or contaminated fluid. Flushing the fluid is fairly straight forward. The car must be on jackstands with the front wheels in the air for the wheels to turn freely. A PVC hose is attached to the return line on the reservoir and directed into a bucket awaiting below. The return hole on the reservoir is blocked allowing fresh fluid to be added and cycled through the system as the wheels are turned. Old fluid rushes through the system and into the bucket. When the fluid changes from dark red/ brown to bright red, the system has been flushed. Care must be taken not to let any air into the inlet tube. Most Toyota/Lexus/Scion vehicles use Dextron III automatic transmission fluid (ATF, as written on the reservoir cap) in the power steering system. Do not use power steering fluid. Procedure applies to many vehicles such as the Toyota, Camry Corolla, Yaris, Avalon, Solara, Sienna, Highlander, Matrix Rav4, 4Runner, Scion tC, as well as the Lexus ES300, ES330, ES350, RX330, RX300 and RX350. It is recommended to change the power steering fluid every 4-5 years or 60-80K miles, or whenever the color appears dark red, brown or contaminated. Refill the reservoir to the full-cold mark and recheck the fluid after a test drive. Stiff steering is more likely the result of a loose power steering belt or a failing pump. Whining noise can be caused by dry pump bearings or bubbles in the the fluid.

How Windshield Wipers Work
Here's how the windshield wipers work to clean the front window on your car. The windshield wipers move in a repetitive translation sweeping motion across the windshield. This motion comes from a motor, that rotates. Using a crank slider (push pull rod) in addition to a four bar linkage, the repetitive sweeping motion is achieved from the wiper motor. The wiper motor assembly consists of a spiral gear that engages the drive gear. This prevents the wipers from being forced down by hand. This also provides torque multiplication and speed reduction. On the back of the drive gear is 3 contacts with a break in it at the home position. When the break lines up, the position of the gear indicates The park position of the wipers, breaks the drive circuit, and thus the motor knows when to come to a stop. The wiper switch contains all of the electronics for the intermittent function. The motor itself has a resistor for built in hi and low speed control. A steel wiper blade consists of small linkages that attach the frame to the blade. This helps to distribute pressure across its surface and is called a whippletree mechanism. Finally, the washer tank, consists of the level sensor and pump. The level sensor is a reed switch, simply a magnetic switch that turns on when the float drops below a certain level to turn on the warning light on the dash board. The pump is a tiny DC electric motor with a small impeller to provide fluid flow from the tank out to the nozzles. Automatic rain sensing wipers use an infrared sensor on the inside of the top of the windshield to sense rain droplets through reflection. A computerized system then activates the windshield wipers accordingly to keep the windshield clear. The wiper and washer system in this video was demonstrated in a 2001 Toyota Corolla.

How a CV Axle Works
Here's how a CV Axle works to turn your car's wheels. The constant velocity axle links the rotational motion of the transmission to the hub and thus turns the car's wheels. Generally, CV axles are used on the front of FWD or AWD cars on vehicles with independent suspension. The main advantage of the CV axle is that it allows for a very high degree of articulation, while still rotating its input and output shafts at the same speed. This is ideal for the front wheels which move up and down with the suspension, and turn sideways to steer. The inner CV joint consists of a sliding tripod housing, that allows the axle to extend or contract. Inside, a carrier with needle bearings holds 3 rollers that allow for a small degree of swing. The carrier looks like a fidget spinner. The outer CV joint does not telescope, however it has a very large degree of articulation, which is needed near the steering axis. It consists of an inner bearing race, a carrier, and the outer race or housing. the bearings are allowed to pivot about the central axis, but cannot rotate - allowing for constant rotation to be transferred from the input to output. Rubber boots cover each CV joint and are typically packed with grease. Interestingly, the grease types appear different for each joint. Boot failure is the major cause of worn CV axles, once dirt enters the system and causes excessive wear. This axle was disassembled from a 2001 Toyota Corolla and opened up to see what's inside and how it works.

How a Shifter Works
Here's how the automatic transmission shifter on your center console works to shift gears. The gear shifter on your car is responsible for providing the driver an input method to changing the direction of the transmission in an automatic car. It is also a safety device preventing the shifter from being bumped into gear, ruining the transmission. Two mechanisms are at play, to protect those around the vehicle and the transmission itself. The park - brake lockout secures the shifter in the P position until the key is in the ignition and the brake is depressed. The shift control computer, located underneath the shifter, will determine if these conditions are met and activate a solenoid to move a tab to allow the shifter to move. The second mechanism at play is a detent rod that glides along a toothed profile. The rod must be pushed down (the button on the shifter depressed) in order for it to move into gear. Manual transmissions do not have a park lockout or a toothed profile preventing certain gears from being selected, and hence must be used with caution. This shifter was taken out of a 2001 Toyota Corolla with a 4 speed automatic transmission.

How to Hotwire Your Car
Stuck without keys and need to get home? As long as you've got your toolbox you can hack into your car's ignition, start it up and drive it home. This video demonstrates how easy it is to hack into your vehicle's steering column, remove the ignition switch and start the car. But it doesn't end there - next you'll need to bypass the steering lock. This will not leave any traceable damage and is completely reversible once you do find your keys again. To access the plastic panels around the steering wheel, the airbag and steering wheel must be removed. Then, the two screws behind the steering column can be removed. Following the thick wires, you'll locate the ignition switch behind the ignition cylinder. Two Philips screws are removed and then the switch can be pulled off the cylinder. a flat screw driver can then be used to start the car. To tackle the steering lock, there are two security bolts need to be removed and the ignition lock assembly can be freed from the steering column, allowing you to drive away! Note, if your car has an immobilizer, this will be more difficult. Check out my immobilizer hacking video here: https://www.youtube.com/watch?v=qRz2b1S2PGk Disclaimer: Only try this on your parents car. Using this method to start any other car could be illegal if the owner hasn't give you permission. This is not the way thieves would steal a car.

How the Engine Lubrication System Works
Here's how the engine oil works to lubricate the moving parts in your engine. Engine oil begins and ends its journey in the oil sump, at the bottom of the car's engine. An oil pump, driven by the crankshaft, sucks oil up through the pickup tube and pushes it through tiny machined galleries in the engine block to lubricate key components. Oil pressure is created when oil flow is let through a tiny hole. The hole acts like a restriction, as the oil is let through at a high velocity, sufficiently coating and lubricating essential parts. Oil then flows from the pump to the filter. The filter consists of an anti-drain back valve and a bypass valve. An OEM Toyota filter is taken apart and a paper filter is discovered to be the filter material. Further down the line, the oil flows to the crank bearings, and up through the connecting rods to shoot oil at the piston walls and connecting rod bushings. The oil control ring on the piston are what's responsible for scraping excess oil off the cylinder walls so it doesn't get burned during combustion above the piston. An oil galley feeds the head of the engine up near the top. It first leads off to lubricate the camshaft bearings (through the hollow camshaft), before splitting off into the variable valve timing solenoid and into the VVT-i gear. A small channel leads off the head to pressurize the timing chain tensioner on the timing cover. A small squirt of oil also lubricates the timing chain itself. Any remaining oil in the head, block, crank case or timing cover is left to drain down into the oil sump, where the oil is cycled back around into the lubrication system all over again. The engine demonstrated in this video was from a 2001 Toyota Corolla with the 1ZZ-FE VVT-i engine.

Toyota Front Strut & Mount Replacement
Here's how to diagnose and replace the front strut or strut mount on a Toyota with MacPherson strut front suspension. For more information on how automotive suspension works, see my video here: https://www.youtube.com/watch?v=MraNBaCmcok The MacPherson strut front suspension consists of a coil-over strut type support that bolts directly to the steering knuckle. It turns as an assembly when the front wheels turn, pivoting on the lower ball joint at the bottom, and the upper strut mount at the top. After years of wear and tear, the ball bearings inside the strut mount, or the rubber bushing can fail and come loose. This will cause a clunking sound going over bumps, or an issue with memory steer or a constant pull to one side that can't be fixed with alignment. Furthermore, the struts which are responsible for damping the bouncing action of the spring may leak its oil and not be able to control the wheel motion over bumps. This may result in a bouncy, uncontrollable ride and cupped tire wear. Typically, QuickStruts can be used to replace the MacPherson strut as an assembly. In this video, the strut is taken apart using spring compressors to change out a worn strut bearing. Once the strut is disconnected from the vehicle (14mm strut mount bolts, 22mm lower knuckle bolts, 12mm brake hose line, 17mm stabilizer link nut), spring compressors are employed to compress the pretension on the spring. The 19mm nut is removed from the top of the damper, and the strut can be disassembled. If the bellows and spring seats are worn, it is recommended to replace them while the strut is taken apart. The strut mount used in this video was from Mevotech, part number MP904989. The vehicle demonstrated here is a 2004 Toyota Camry V6.

Spark Plug Replacement: Toyota / Lexus 3.0L V6
Here's how to replace the spark plugs on a Toyota with the 3.0L V6 1MZ-FE engine. The procedure is the same for the Solara, Camry, Avalon, Lexus ES300 and similar to Toyota Sienna, Highlander and Lexus RX300. These older engines use a metal intake plenum that does not need to be removed to access the rear spark plugs, unlike the newer 3.3L and 3.5L Toyota/Lexus V6 engines. You will need a few extensions, wobbly sockets, a spark plug socket and a 3/8" ratchet to remove the plugs, especially along the rear bank. Use anti-seize on the threads to prevent them from seizing in the engine. Die-electric grease is also great for where the spark plug makes contact with the ignition coil. Some models of 1MZ-FE engines come with six coil packs, while others have 3 coil packs in front and 3 wires running to the rear spark plugs (waste spark ignition). For waste spark ignition, use dual electrode platinum plugs to prolong electrode wear, and do not gap new plugs. Changing the spark plugs is recommended at 8 years or 192,000km. It will help smoothen out a rough idle and give you slightly better fuel economy. The color of the old spark plug can tell a lot about the health of your engine.

Honda Idle Air Control Valve, PCV and Throttle Body Cleaning
Here's how to clean the idle air control valve, throttle body and PCV valve on a 4 cylinder Honda Accord, Acura TSX, Honda CR-V or Element. A dirty idle air control valve (IACV), throttle body or PCV valve can cause rough idle, idle that is too low or high, dull throttle response or a car that doesn't want to stay started once cranked. Carbon deposits build up on the butterfly valve and IACV solenoid, causing them to stick and function improperly. Sometimes this may result in a check engine light, P0505, P0506, or P0507. While often the solution is to replace these components, it can get quite costly and cleaning them can prolong their life and be more cost effective. On most vehicles, throttle body removal is required to access the IACV. The airbox and its accompanying hoses must first be removed, followed by the throttle cable and two coolant lines. Four 12mm bolts and nuts hold the throttle onto the intake, upon which the IACV can then be removed via two philips screws. Sometimes these screws strip out or are hard to get to on the vehicle and you'll have to use a vise grip to turn them out. Once everything is apart, use carb cleaner, a rag and toothbrush to clean everything out, and put it back in the order it came apart. Make sure all gasket surfaces are clean, and change the air filter while you're at it. Cleaning the mass airflow sensor with electrical contact cleaner is a good idea, if it isn't seized in the air intake. The PCV valve is on the passenger side of the car, above the alternator. Once the hose is removed, a 17mm deep socket can be used to unscrew it from the engine block. If it rattles when shook, its working fine, but if the ball pin is stuck it won't rattle and should be cleaned and/or replaced. Once everything is back together, pull the battery terminal to reset the ECU to relearn idle. Top off the coolant and allow the system to bleed out all the air by leaving the radiator cap loose.

How Automotive Safety Glass Works
Here's how the laminated front windshield and tempered side windows help to protect you from injury. When glass is broken, it can large sharp pieces that can harm surrounding people. Automotive glass is specifically designed to fail with a certain characteristic, depending on its application. This characteristic is determined by its manufacturing process. The front windshield on all modern vehicles are laminated. That means there are two thin layers of glass with a poly laminate layer in between. The glass sandwiches this layer, making it completely transparent. The laminate is flexible and sticky, and holds the pieces of glass together if it is broken. The windshield layers are not tempered, therefore break into large pieces. However because they're being held together by the laminate layer, they cannot penetrate the cabin and harm any passengers. This also prevents other objects from penetrating the cabin directly while driving straight ahead. Side windows on most modern vehicles are made of tempered glass. The glass is heat treated and then cooled. This adds lots of strength to the glass. Its most sought after characteristic as a safety glass is when it breaks, it breaks into very small tiny harmless pieces that do not have large sharp ends. Therefore this glass presents minimal risk to occupants in the vehicle. Some luxury vehicles have side windows that are made of tempered-laminated glass. Two tempered sheets of glass sandwich a laminate layer, providing addition protection against penetration, the strength of tempering, and additional sound proofing.

How an Air Intake Works
Here's how the air intake system works on your car. The air intake system has been designed by the car manufacturer to provide a balance of airflow, sound tuning and packaging capabilities. It is responsible for supplying the engine with sufficient air to ensure optimal combustion. Key components of the air intake system include: - Air inlet tube - Air intake resonator - Air filter housing - Air filter - Mass airflow sensor - Evaporative emissions purge valve - Accelerator pedal - Throttle body - Intake plenum - Various vacuum hoses This video demonstrates where these parts are positioned as part of the larger assembly in the car. It will then break down each individual component and explain how it works. The air intake tube sucks air from the front of the engine bay near the radiator cradle. The air then proceeds down into the air resonator box, mounted behind the bumper, below the headlights. The resonator will reduce any unwanted sounds and tunes the intake to match the vehicle's characteristics. The air then travels to the air box, where it is past through an air filter. The filter is designed to maximize filtration area, with a corrugated felt pattern. The mass air flow sensor and EVAP purge valve are also mounted to the air filter box. The EVAP purge valve is a simple check valve that allows air to be vented to the intake system from the gas tank. It is activated by a solenoid which is controlled by the ECU. Enough ventilation will enrich the air with gasoline vapours before it enters the intake manifold and the engine. The Mass air flow sensor, or MAF sensor, is responsible for detecting how much air is flowing through the intake. There are two resistors inside upon which the air flow and cool down when a current is applied. When more air flows past, it cools further, decreasing resistance and increasing the current. The ECU will detect the change in current and correlate it to density (and hence mass) of air flowing through the sensor. According to the ideal gas law, the pressure can go up or the temperature can drop accordingly, but the MAF sensor can still determine the mass of air flowing through. This is ideal for automotive applications, where atmospheric conditions can vary drastically. The MAF sensor is also fitted with an intake air temperature sensor or IAT sensor to tell the ECU how warm or cold the incoming air is. The throttle body controls how much air enters the air intake manifold through a butterfly valve. The accelerator pedal opens the throttle body with a cable linkage. Many newer vehicles use a drive - by - wire setup, where the gas pedal has an electronic linkage via an electric motor to open the throttle plate. The throttle body also has various connections to vacuum lines, as well as the idle air control valve below, two coolant lines to prevent freezing, and the throttle position sensor. The air intake manifold distributes the air from the throttle body across all the pistons. It is made up of a casted section where the throttle body mounts, and aluminum tubing that is bent to shape. Newer vehicles use plastic intake plenums to save weight and reduce cost.

How a Car's Cooling System Works
In this video, each component of the cooling system is removed from a 2001 Toyota Corolla and cut into pieces to demonstrate what's inside and how it works. The cooling system is responsible for regulating engine temperature during operation. Maintaining optimal temperature is key to efficient combustion. As the engine produces heat, coolant circulates inside the engine block, absorbing the heat. Hot coolant is piped through the radiator hose to the top of the radiator. The radiator cap is responsible for building pressure inside the radiator to roughly 15PSI. This increases the heat capacity of the coolant. An overflow reservoir is attached to the top of the radiator as coolant warms and expands out. When cooled, the coolant will get sucked back into the radiator. The hot coolant then flows across many tubes in the radiator, exchanging heat with the surrounding air. This is aided by electric cooling fans, and the vehicle driving through the air at speed. Near the bottom of the radiator is an encased tube that runs automatic transmission fluid through it, to help cool the transmission. The coolant then makes its way through the lower radiator hose, where the thermostat controls the flow of coolant in the engine. The cooling system is self regulated and is not controlled by the ECU directly (with the exception of the cooling fans). The coolant finally makes its way back to the water pump, where it is pumped back through the engine block and cycled again. There are separate circuits for the throttle body and heater core that take heat from the engine block.

Used Tire Buying Guide
Here's a few tips on what to look for when buying used tires for your automobile. Buying used tires is a great way to save money, while improving traction and safety. Its best suited for vehicles that you might not be keeping for too long, reselling, scrapping or returning as a lease. However if you will be keeping the car around for a few more years, its probably more cost effective to get new tires. A tire is cut away and the internal structure is demonstrated. All tires have a general life span of about 6 years. Typically all season tires come with 10/32" of thread, and can go down to about 4/32" of thread before it starts getting slippery in the rain or snow. Details about tire thread depth, condition and age are discussed. You must also consider different tire types for what vehicle you drive, be it an all season touring tire for family cars, a light truck tire for SUVs, vans and pickups, a performance tire for race cars, or winter tires for areas that require them. The final consideration should be the price that your getting the used tires at. Once the installation costs are factoring, calculate if its worth buying a used tire. For example, a used tire may last you one year, but is it worth paying 40% of the new tire price for only one year of service? With a good quality set of used tires, you can improve your traction, safety and of course save a lot of money. You may even get lucky and find a set of used rims with tires already installed that can fit your vehicle.

How Shock Absorbers and Struts Work
Here's how the shock absorbers or struts work to keep the wheel on the road in your car. The weight of a car is supported by suspension coil springs. When you hit a bump, that coil spring compresses, absorbing the impact of that bump. However, the coil stores that energy and releases it, and left undamped, can cause for a bouncy uncontrollable ride. Enter the damper, which is responsible for controlling and limiting the bounce of the spring to maintain proper tire contact and comfort. It consists of a piston that retracts and expands with suspension travel. Inside the piston are valves that control the flow of oil through orifice holes. Thus the velocity of the piston is controlled through the oil flow, causing a dampening effect. This video grinds open and breaks down a strut from a 2001 Toyota Corolla. It explains the major components of the strut and its function as part of the entire strut assembly and the vehicle in a mass-spring-damper type system. The strut consists of the piston, piston valve, pressure tube where the oil pressure is built, a base valve at the bottom of the cylinder, and a reserve chamber outside the cylinder in the housing of the body of the strut. When the piston compresses, oil flows through both valves at varying rates - depending on the shock tuning. Each valve can be individually tuned to control compression and extension of the piston independently. Shocks vs Struts: In this video the term shocks and struts are used interchangeably since the focus is on the damper portion of the suspension. Struts are the complete assembly when a coil is placed over a damper, while shocks are a separate damper with the coil spring (or leaf spring) placed separately on another part of the suspension.
