An ACDelco GM Original Equipment Engine Auxiliary Water Pump is used in some vehicles to pump engine coolant during certain operating conditions. While your engine's main water pump is mechanically driven and stops when the engine does, an auxiliary water pump is electric and able to circulate coolant after the engine is shut off, keeping coolant flowing to where it needs to go. These original equipment auxiliary water pumps have been manufactured to fit your GM vehicle, providing the same performance, durability, and service life you expect from General Motors. ⚠ WARNING: Cancer and Reproductive Harm - https://www.P65Warnings.ca.gov
