GM Genuine Parts Engine Cooling Fan Pulleys are designed, engineered, and tested to rigorous standards, and are backed by General Motors. These engine cooling fan pulleys are located on the engine water pump, and transfer power from the drive belt to the engine cooling fan, as well as the water pump. Pulley wear from the abrasive effects of road dirt and bent pulleys can cause belt noise, wear, and slipping. GM Genuine Parts are the true OE parts installed during the production of or validated by General Motors for GM vehicles. Some GM Genuine Parts may have formerly appeared as ACDelco GM Original Equipment (OE).
