Toyota and Scion Thermostats

The thermostat in a car sits between the engine and the radiator regulating the flow of the coolant from the radiator to the engine to prevent it from overheating. The thermostat turns the flow of coolant on and off depending on the temperature of the engine. When the engine is cold it closes the flow and when it is sufficiently warm allows the coolant to flow and dissipate heat. When the thermostat malfunctions, the engine can start heating too quickly which may lead to overheating and damage. Malfunctioning thermostat needs to be replaced at the earliest.
