The function and purpose of Thermostats.

Your car or truck has a water-cooled motor, 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 3500 HD thermostat responds by directing coolant to the radiator. Now your coolant gets cooled as it recirculates through your GMC Sierra 3500 HD engine; keeping it within a specific range of temperatures that are determined for the engine to achieve the best balance between power, fuel efficiency, and emissions... all thanks to the thermostat.
