The piston pin connects the piston to the connecting rod. It allows the connecting rod to pivot while the piston moves up and down in the cylinder.

Compression is the amount of air pressure that is generated by the Piston inside the Engine Cylinder as it is raised from its lowest point to its highest point by the rotation of the Crankshaft. Usually the amount of Compression in an Engine is determined by the Compression Ratio.

Haldex Fluid is a specialized hydraulic oil that is used in the Haldex Intelligent All Wheel Drive System. The Haldex AWD System controls the amount of drive torque to each individual wheel and can direct up to 85% percent of the drive torque to a single wheel when the other three wheels are losing traction.

When an automatic transmission is malfunctioning, it may exhibit one or more symptoms, such as harsh or delayed shifting, the loss of one or more gears, engine RPM "flare ups" between shifts, fluid leaks, slipping or lack of power to the drive wheels, and/or Check Engine Light or transmission overdrive illumination. When these types of symptoms occur, it is important to have an Automatic Transmission Diagnosis.

When the air conditioning system is malfunctioning, it can exhibit one or more symptoms such as a lack of cold air, only cooling the front area or one side of the vehicle, and/or not blowing cold air from the panel vents. When these types of symptoms occur, it is important to have an Air Conditioning Diagnosis.

The throttle position sensor is a key component of the emissions system. It rests on the throttle body of most vehicles and is typically held on with two to three fasteners.

The engine coolant temperature sensor (ECT) is a primary sensor that influences both ignition timing and fuel mixture. On most vehicles, it rests on the intake manifold and is usually threaded into a coolant passage.

The manifold absolute pressure (MAP) sensor tells the powertrain control computer how hard the engine is working (how much load is being applied), which influences both the ignition timing and fuel mixture. The sensor is mounted on the intake manifold, often by the throttle body, or on a separate bracket on the firewall.

The crankshaft position sensor tells the powertrain computer (PCM) the rotational speed of the crankshaft. This information is used to control ignition timing and fuel delivery.

The most common type of brake booster uses engine vacuum to add force to the pressure being applied to the master cylinder. It is installed between the brake master cylinder and the driver's brake pedal and is located in the engine compartment.

The windshield washer pump may need to be replaced when the windshield washers stop spraying the cleaning fluid on the windshield. How to Replace the Windshield Washer Pump Empty the washer fluid out of the washer pump reservoir Lift the washer reservoir and disconnect the hoses and washer pump electrical connector Remove the washer reservoir Remove the old washer pump and install the new pump Reconnect the hoses and electrical connector Install the reservoir Fill the reservoir and verify that the system works properly Note: Be sure to use washer pump fluid—not water—because water has minerals that can clog the wiper spray nozzles.

The engine computer or PCM/ECM manages the performance of the engine, the emissions system, and in some cases, controls the transmission and ABS systems. When replacing the PCM, first make sure there is no evidence of water getting into the area where the PCM is located or the new PCM could be ruined.

The knock sensor tells the powertrain control module (PCM) when the engine is pinging or knocking. How to Replace the Knock Sensor Note: Many vehicles require removal of at least part of intake manifold to access the knock sensor.
