How thermostat works?
An electromechanical thermostat typically contains either a bi-metal coil or a metal strip. When the temperature changes, this coil or strip will move, causing a vial containing mercury to tip to one side. The mercury flows to one end of the vial, signaling that the heating or cooling needs to be turned on.
How car thermostat works?
The thermostat is basically a valve between the engine and the radiator. When the coolant in the engine gets too hot, this valve opens, letting it pass to the radiator where it will cool down. If it is not heated, the thermostat stays closed, allowing the coolant to continue circulating inside the block.
