A-Premium Water Pump with Thermostat for GM 4.8L/5.3L/6.0L Trucks & SUVs – Complete Kit, Corrosion-Resistant

The A-Premium Water Pump with thermostat is a direct-fit replacement cooling assembly engineered to restore reliable coolant circulation and temperature control in compatible GM 4.8L, 5.3L and 6.0L engines.

If your Silverado, Sierra, Tahoe, Yukon, Escalade, Hummer or other supported GM vehicle shows signs of coolant loss, overheating, or uneven cabin heat, replacing the water pump with a complete unit that includes the thermostat, gasket, pulley, and mounting hardware is a practical service to return the cooling system to factory-like operation. This A-Premium assembly is manufactured to tight tolerances and treated for corrosion resistance so it fits and functions as a dependable direct replacement for OE part numbers such as AW6009, 12600767, and related references.
