What is a Car Thermostat?

A thermostat opens or closes a valve to control coolant flow between the car's radiator and engine. It responds to changes in temperature. The valve itself operates through a wax-container element. As coolant temperature increases, the fluid (or wax) container melts and enlarges, which, in turn, pushes a small bar, dividing a centre plate from its mounting base to expose the valve. The thermostat also helps to keep your engine running smoothly and reduces engine wear. Ensuring optimum fuel economy and harmful emissions.

If your car starts overheating quickly after starting it, or the dashboard temperature gauge drops below normal, it might be an indication that your thermostat has failed.
