Have a failed or leaking water pump in your 2001 to 2005 GM Duramax Silverado or Sierra? Look no further! This Merchant Automotive kit has the seals, gaskets, flywheel, and cover you need to get the job done right.
This pump has the impeller and drive gear TIG welded to the shaft for increased durability, as well as to avoid problems associated with gear slippage and impeller walk. The seal between the housing and gasket is pre-installed, and the bolts are torqued. It’s best practice to replace the harmonic balancer bolt when reassembling. This bolt is torque to yield and should only be used once.
