GMC Sierra 1500 Water Pump

SKU SIERRA-1500-WPUMP
Price

$114.99

The water pump circulates coolant through the engine and radiator to prevent overheating, especially important when towing or hauling. A failing pump can cause coolant leaks, overheating, or a whining noise.

Sized to fit the cooling system of the GMC Sierra 1500 5.3L V8, this pump installs directly onto the factory mounting points.

Built with a durable impeller and sealed bearing, it helps keep your V8 running at a safe operating temperature.

Reference: OE/interchange US8918

"The socket set is top-tier quality. Heavy-duty steel that handles real torque without slipping. Better than the big box store brands honestly."
