01-05 GM LB7/LLY Water Pump - 10179

Duramax Water Pump 01-05 LB7/LLY with Gaskets and O-rings Due to issues that have shown to arise on water pumps, any pump purchased from us will have the impeller and drive gear TIG welded to the shaft for durability. This will avoid any problems that are associated with gear slippage and impeller walk.
