A worn bearing or leaking seal can show up as a whine or grinding from the pump area, coolant stains near the pump, or a temperature gauge that climbs. If the pump is the cause, this one replaces it. Since a leak elsewhere gives similar signs, first look over the pump, belt and hoses for coolant traces with the engine off and cool. One pump serves each engine, so you need just one.
