The ACDelco GM Original Equipment Engine Crankshaft Pulley is a GM-recommended replacement for your vehicle’s original component. It is attached to, and driven by, the front of the engine crankshaft. It is connected to various engine accessory drive components by a belt drive system and ensures components such as the water pump, alternator, and power steering pump receive power from the rotating crankshaft to perform their vital functions. The crankshaft pulley also works as a harmonic damper to decrease crankshaft torsional vibration. This original equipment engine crankshaft pulley has been manufactured to fit your GM vehicle, providing the same performance, durability, and service life you expect from General Motors.
