Product Overview

A failing water pump can leak coolant from the seal area, develop bearing play or noise, or stop circulating enough coolant to control engine temperature under load.

Replacing the pump restores mechanical coolant circulation through the engine and radiator, while the belt, hoses, thermostat and cooling fins should be inspected at the same time.
