Product Overview

Coolant seepage, shaft play, bearing noise or overheating under load can point to a failing pump on high-mileage heavy-duty engines.

Replacing the worn pump restores engine-driven coolant circulation once belt drive, thermostat, radiator and coolant condition have also been checked.
