A worn pump can show up as coolant leaking near the pump, a whine or growl from the bearing, or an engine that runs hot. A thermostat, a radiator hose, a slipping belt or a low coolant level can cause the same overheating, so find the cause before buying a pump. Check the coolant level only with the engine cool. Each engine takes one pump.
