ACDelco Water Pump (With Housing) 251-817

The ACDelco Water Pump (With Housing) 251-817 will replace the failed or weeping water pump on your GM 6.6L Duramax L5P. The water pump plays a vital role in cooling the engine by circulating antifreeze throughout the cooling system. A water pump will often start leaking (or weeping) to let you know it's time to be replaced. This water pump is a genuine ACDelco unit that came on your truck when it left the factory.
