Gates 45004WT Engine Water Pump - Main

Gates Water Pump for GM V8 Cooling Service

The Gates 45004WT engine water pump is a standard replacement for select Chevrolet, Cadillac, and Pontiac applications that use accessory-belt drive. It combines a cast aluminum housing, stamped steel impeller, and an integrated thermostat and housing for a direct-fit cooling system service part.

Built as part of the Gates Water Pump (Standard) line, this unit is engineered for OE-quality fit and consistent operation. Gates tests seals and bearings for function and performs leakage checks on both the casting and the assembled pump before release.

• Noise from failing pump bearings or seals

• Cooling-system leaks at the pump casting or gasket surfaces

Installation Notes

Verify reverse-rotation application, outlet layout, and accessory-belt drive before installation. Inspect the mating surfaces, replace worn gaskets as needed, and confirm the pulley alignment during reassembly. This part cross-references ACDelco 251-728 and Airtex AW6689 for the same application.
