What is a car thermostat?
A car thermostat is part of an engine’s cooling system. It controls the flow of antifreeze by opening only when the engine reaches a set operating temperature. This allows the engine to warm up faster.FeaturesA car thermostat includes a hinged opening that allows it to open and close, depending on engine temperature.BenefitsBy allowing the engine to reach its normal operating temperature quickly, the thermostat helps the car warm up quicker.IdentificationThe thermostat is a round device located in the thermostat housing, which bolts directly on the engine underneath the upper radiator hose.ConsiderationsThermostats can fail in three positions: open, closed or somewhere in between. Although any faulty thermostat should be replaced quickly, a thermostat that fails closed prevents antifreeze from entering the engine, which causes it to overheat quickly.WarningNever operate a vehicle without a thermostat.
