Good To Know

Q: Does this pump require a wiring and relay setup? A: Yes, electric water pumps typically need a switched power source and a relay rated for the pump's current draw. Confirm the harness and controller requirements for your application before installation.

Q: Will this fit my specific big block Chevy build? A: Fitment depends on the accessory drive, pulley setup, and block configuration. Verify clearance and mounting points against your engine before ordering.

Slight variation in finish or dimensions may occur between production runs, and fit can depend on serial number, so confirm compatibility before ordering.
