5 Reviews
SKU: 10541


Includes flywheel lock, all gaskets, and o-rings for installation. Seal between housing and gasket is installed. Bolts are torqued. Some existing hardware will be re-used. It is best practice to replace the harmonic balancer bolt when reassembling. Bolt is torque to yield and should only be used once.


Complete solution to a leaking water pump!

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!
