Your car or truck has a liquid-cooled engine, and its thermostat keeps the coolant flowing in the right direction so that your engine can maintain a constant and ideal operating temperature. On start-up, the thermostat remains closed; bypassing the flow of coolant through your radiator. This cycles the coolant through the engine block and gets it hot. Once it reaches the right temperature, your GMC Sierra 1500 HD thermostat responds by directing coolant to the radiator. Now your coolant gets cooled as it recirculates through your GMC Sierra 1500 HD engine; keeping it at a steady and controlled temperature ideal for engine performance... all thanks to the thermostat.
