Aisin WPFD-718V OE Replacement Engine Coolant Water Pump Assembly

The Aisin WPFD-718V is an OE-engineered engine coolant water pump assembly built to original equipment specifications. Aisin Automotive Casting Tennessee is the manufacturing arm of the Aisin Group — the world's largest OEM water pump manufacturer — supplying original equipment water pumps directly to major automakers. This part meets or exceeds the same standards as the pump installed on the vehicle at the factory.

Key Features:

• OE Engineered & Manufactured — designed and produced to original equipment specifications for a direct-fit, no-modification installation
• Aluminum die-cast housing — reduces weight while providing superior strength and heat dissipation compared to iron alternatives
• Silicon carbide (SiC) mechanical seal — advanced seal material that resists wear and heat buildup, significantly reducing the risk of coolant leakage
• Triple lip bearing seal — protects the bearing from coolant intrusion should the mechanical seal ever weep, extending overall pump service life
• Precision-balanced impeller — ensures consistent, efficient coolant flow throughout the engine cooling circuit
• Factory-matched gasket surface — machined mating surfaces for a leak-free installation

Aisin water pumps are the same units supplied to OEM assembly lines, sold under the Aisin brand for the aftermarket. Replacing a worn or leaking water pump with an Aisin unit restores original cooling system performance and helps protect the engine from overheating damage.
