Buick Nailhead Aluminum Water Pump (Satin)

Upgrade your 1962–1966 Buick 401 or 425 Nailhead engine with this high-flow satin aluminum water pump. Designed to prevent overheating in street rods, muscle cars, and performance builds, it features a precision-cast powdered metal impeller with oversized vanes for maximum coolant flow—even at low RPM. A direct factory replacement for March Performance Style Track and Nostalgia Track serpentine systems.
