INFO
Chevy Silverado Water Pump 12708957 is a belt-driven direct replacement for selected 2019-2021 5.3L and 6.2L V8 gas applications. The assembly circulates coolant through the engine and radiator while the installed pulley is driven by the engine belt. It is intended for cooling-system service after inspection finds possible pump leakage, bearing noise, shaft movement, or circulation concerns. Those signs can also involve hoses, the thermostat, the radiator, or other cooling components, so inspection should identify the repair scope before parts are ordered.
The pump combines an aluminum housing, a steel impeller, the installed pulley, coolant outlets, and the application-specific mounting structure. The package includes one engine water pump assembly with pulley and two shaped gaskets. Chevy Silverado Water Pump 12708957 also fits the listed GMC Sierra, Chevrolet Tahoe and Suburban, GMC Yukon, and Cadillac Escalade applications when the model year and engine match. It is not listed for diesel or earlier-generation applications. Compare the mounting points, pulley, outlet locations, electrical sensor connection, and gasket shapes with the removed assembly, then follow the vehicle service information for belt routing, coolant refill, and system bleeding.
Features
- Direct-replacement, belt-driven water pump for the listed 5.3L and 6.2L V8 gas applications.

- Steel impeller supports coolant circulation through the engine cooling circuit.
- Installed pulley is included as part of the water pump assembly.
