A thermostat, as used in a motor vehicle, is essentially a heat actuated valve which, when open, allows coolant to cycle through the cooling system. The coolant absorbs heat from the engine and cycles it to the radiator, where the heat is exchanged to the ambient air which flows through the radiator fins. Air conditioning actually works in a similar manner, but is not affected by the thermostat - the thermostat does, however, allow you to have heat in your vehicle.
