Truck Parts And Their Functions

Item	Sample Picture	Function
Drive Belt		The drive belt, also known as the fan belt, provides power to many important components located near the front of the engine. The drive belt powers the alternator, water pump, power steering pump, and AC compressor. Each of these components contains a pulley where the drive belt wraps around.
Electronic Throttle Pedal		The suspended electronic throttle pedal is designed to provide an electrical signal to an engine control module in response to the driver's demand for engine power.
Engine Mounts		Three mounts support the engine and transmission, holding a total of almost 1800 lb (816 kg). Two of the engine mounts support the rear of the engine and transmission assembly. The third supports the front of the engine/transmission assembly. Each of the rear engine mounts is bolted to the inside of the frame rail near the flywheel housing. These mounts support legs which are bolted to the flywheel housing. Engines use a rear engine leg that rests flat on the mount.
