Your car's thermostat measures the temperature of your coolant. If it senses the coolant is cool, it sends it back through your engine, but if it senses that it's too hot, it directs it to your radiator so that it can be cooled before it goes back to your engine. Your thermostat is a critical part of your car's cooling system, and if it isn't working correctly, it can lead to damage with your radiator or your engine.
