Product Overview

Coolant leakage from the pump seal, pulley wobble, bearing noise or overheating under load can indicate the water pump is no longer circulating coolant correctly.

Replacing the pump restores coolant flow through the engine and radiator once the rest of the cooling system has been inspected.
