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.

Kit Includes 


GM Duramax Silverado & Sierra 6.6 V8 Diesel Trucks

2001, 2002, 2003, 2004, 2005

Only way this kit could get better is if it came with a 36mm 3/4inch drive socket. But the Flywheel lock did its job and everything went together perfectly.

pump it up!

Always the fastest shipping. Part is great, No issues with install or parts missing from the kit. Other than I wished they just included the bolt in the kit for the extra 16. Instead of ordering it separate. They offer the ARP bolt so would just need a drop down selection box for which bolt you want in the kit. Other than that Great part.

Wonderful product

I ordered this pump after a lot of seaching and readin on who was good and who was bad. Mechant had the most recommendations by far. I am so glad i went with this pump. You pay for quality and this is a great price without skipping on the quality of the part. Will recommend to everyone.

I will never get parts anywhere else. If Merchant Automotive doesn’t have it; be careful who you buy from. Bought an AC Delco water pump from Rockauto and it lasted 10k miles.

Great deal!

Everything you need to get the job done. The flywheel tool saved me a lot of time and included all the seals I needed. Thanks again!
