It's a direct-fit replacement for a long list of GM trucks, vans, and SUVs, including the 1999-2013 Chevrolet Silverado 1500, 1996-2005 Chevrolet Astro, 1996-2014 Chevrolet Express 1500, 1991-2000 Chevrolet C2500, and 1996-2005 GMC Safari — plus Isuzu Hombre/NPR, Oldsmobile Bravada, and Workhorse chassis applications. See the Buyer's Guide tab for the full list of 73 applications.
- Mounting hardware: supplies the threaded studs used to secure the water pump to the engine.
- Fresh replacement: gives you new studs when the originals are corroded, seized, or stripped during a water pump job.
- Broad coverage: a single kit serves many GM, Isuzu, Oldsmobile, and Workhorse platforms.
Original water pump studs can corrode or gall over years of coolant exposure and heat cycling, making the old pump difficult to remove and hard to re-torque evenly. If worn or damaged studs are the issue on your application, this kit replaces them so the new pump can be drawn down and clamped properly. Always follow the vehicle service information for the correct torque procedure.
