You probably meant "isn't functioning properly". But even that is not true I don't think. The water pump discharges to two outlets, (three outlets if you have turbo) the main one to the radiator, a second tubing feeds the heater core inside the cabin to supply heat. Let's say your thermostat is blocked, I think the heater circuit still flows because coolant returning from the heater core goes to the block to the suction side of the pump forming a circuit.
