<blockquote>The opening and closing of a thermostat is based on the temperature of the coolant running against the "heat motor". The heat motor is operated by a special wax that melts at a given temperature. As the wax melts, it expands and hydraulically pushes a pin that opens the valve allowing coolant to flow. I hope this helps. See the attached article for more details. | <blockquote>The opening and closing of a thermostat is based on the temperature of the coolant running against the "heat motor".
