Coolant stains at the housing, a whining pump or weak heater output can point to a failing pump, but a loose hose or a different fault can show up the same way. Find the cause first: with the engine off and cool, look for dried coolant around the pump and its connections, and leave running tests to a shop. Each vehicle takes one pump.
