Engine Water Pump Kit with Gaskets (OE 12703898)

Engine cooling is not an area to compromise, especially on late-model GM trucks and SUVs. If you have spotted puddles of pink or orange fluid on your driveway, or if you are hearing a localized squealing sound from the front of your engine, your water pump bearing is likely failing. The GM Genuine Engine Water Pump Kit is a 100% brand-new, factory-original replacement assembly engineered specifically to restore optimal thermal regulation. Built to General Motors' precise dimensional specifications, it delivers maximum coolant circulation to shield your cylinders from extreme heat-soak. This complete service package comes pre-bundled with factory-matched mounting gaskets to ensure a reliable, leak-free installation right out of the box.

Key Features

• 100% Authentic Factory GM Component: Designed, engineered, and validated directly by General Motors for an exact-spec drop-in replacement layout.

• Premium Gaskets Included: Eliminates the hassle of sourcing separate seals by bundling factory-matched, high-compression mounting gaskets.

• Precision-Balanced Internal Bearing: High-strength bearing assembly minimizes shaft vibration to deliver dead-silent operation and massive service life longevity.

• Optimized High-Flow Impeller: The internal rotor is aerodynamically tuned to circulate coolant fluid flawlessly through the block and radiator cores under extreme operating demands.

Performance & Benefits

• Complete Thermal Protection: Restores original-equipment cooling efficiency to prevent high-load engine overheating, blown head gaskets, or warped cylinder heads.

• Eliminated Belt Squeal & Drag: A fresh, factory-pressed pulley configuration lines up perfectly with the serpentine accessory drive belt to eliminate friction drag and annoying cold-start chirping.

• Long-Term Hydraulic Integrity: High-grade metallurgical body castings resist internal cavitation and chemical corrosion from modern extended-life antifreeze mixtures.
