Your car or truck has a water-cooled motor, and the device that controls the flow of coolant so that the engine can remain cool is your thermostat. On start-up, the thermostat remains closed; bypassing the flow of coolant through your radiator. This gets the coolant hot so that the engine warms up. Once it reaches an optimal operating temperature, your GMC Sierra 1500 Classic thermostat responds by directing coolant to the radiator. Now your coolant gets cooled as it recirculates through your GMC Sierra 1500 Classic engine; keeping it at a steady and controlled temperature determined for the engine to achieve the best balance between power, fuel efficiency, and emissions... all thanks to the thermostat.
