These Edelbrock Victor series high-volume water pumps are designed for maximum flow and equal coolant distribution in street cars, race cars, tow vehicles, and motor homes. The aluminum pumps have CNC-machined housings with special one-way internal passages that flow more coolant at higher velocities, even at low engine speeds. The CNC-machined, cast iron impellers are larger than other impellers and have curved vanes that produce greater flow with less cavitation. Other features include heavy-duty roller bearing assemblies built to withstand higher torsional loads, billet steel hubs, leakproof seals, and gaskets. Plus, most Victor series pumps are available in your choice of natural cast, polished finishes, or EnduraShine.
