Are you finding that your car’s engine warms up very slowly? Is it not reaching the normal temperature? Or maybe you are experiencing overheating? You could have a faulty thermostat on your hands!
But how can you tell if it is the thermostat that is acting up and not something like a failing water pump, radiator or fan causing the above problems. When a thermostat gives out, it will be stuck in either an opened or closed position.
Basically, a thermostat will start in the closed position, as the engine starts it will help to reach operating temperature. When the coolant levels begin rising, the thermostat will open. This allows the hot coolant in the engine to flow into the radiator, then the water pump will push lower-temperature coolant from the radiator to the engine. As the lower-temperature coolant reaches the car's thermostat, the expanding fluid will contract, closing the thermostat's valve.
