Ford Alum Water Pump Pulley

The Ford Alum Water Pump Pulley by MARCH PERFORMANCE is a precision-engineered aluminum component designed for Ford FE-Series engine builds and restorations. This single-groove V-belt pulley serves as a critical interface between the water pump shaft and the engine's accessory drive system, regulating coolant circulation through the engine block. Whether you're assembling a classic muscle car, updating a vintage Ford, or maintaining OEM-spec cooling efficiency, this pulley ensures reliable belt engagement and smooth rotational transfer.

Manufactured from lightweight aluminum with a clear powder-coat finish, the Ford Alum Water Pump Pulley features a 6.75-inch diameter profile optimized for V-belt compatibility and load distribution. The single-groove design accommodates standard accessory serpentine or traditional V-belts, allowing seamless integration into existing or modernized cooling systems. Aluminum construction reduces rotational inertia compared to cast-iron alternatives, promoting efficient water pump operation while the protective powder-coat finish resists corrosion and oxidation in high-heat engine compartment environments. The compact footprint—measuring 7.45 x 5.9 x 7.5 inches and weighing just 1.89 lbs—makes installation straightforward without compromising durability or performance.

Enthusiasts restoring Ford FE-Series engines—including 427, 455, and 390 cubic-inch displacement variants—will find this pulley essential for maintaining original cooling system geometry and belt tension specifications. It is sold individually and is compatible with MARCH PERFORMANCE water pump assemblies and OEM Ford cooling configurations. Installation requires standard socket and wrench tools; align the pulley with the water pump shaft keyway and torque securely to prevent slippage during operation. This component is ideal for hot rod builders, classic car restoration shops, and Ford performance shops seeking reliable, corrosion-resistant cooling system upgrades.
