GM Genuine Parts Engine Water Pump Adapters are designed, engineered, and tested to rigorous standards, and are backed by General Motors. These engine water pump adapters are metal or plastic housings, which provide a path for engine coolant to enter and exit the water pump and the engine or other cooling system components. 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).
