Product Details

Gates Water Pump (Standard) part number 41023 is built for vehicles that use an accessory belt-driven engine water pump. Gates manufactures each new pump with premium alloy materials and performs functional testing of seals and bearings, along with leakage testing of the casting and assembled unit. That process supports consistent coolant flow and a precise OE-style fit for service work on Buick Skylark, Pontiac Grand Am, and other listed applications.

This part cross-references Airtex AW5043 and GMB 130-1660 for the same application.
