Description
Water Pump Kit with Cover and Seals, L5P Duramax | 2017-2025
This water pump kit replaces the water pump on the 6.6L L5P Duramax in 2017-2025 Chevy Silverado and GMC Sierra 2500HD and 3500HD trucks. We assemble it so the pump, the seals and the tool the job calls for come in one box, and you aren't stuck waiting on a missing O-ring halfway through the repair. It includes a water pump assembly with the housing, the water pump to front cover seal, the thermostat bypass pipe gasket and O-ring, and a flywheel lock.
Note: The crankshaft balancer bolt has to be removed to replace the water pump. The factory bolt is a one time use bolt and must be replaced. It is not included.
