It circulates coolant through the engine block and radiator to prevent overheating, and must be replaced when bearings fail, seals leak, or the impeller wears out, typically indicated by coolant drips, bearing noise, or overheating. This kit includes the water pump and necessary O-rings for a complete installation. It features a stepped EGR cooler mount, so check your engine’s mounting surface; a standard flat mount pump will not fit.
