The function and purpose of Thermostats.

Your car or truck uses liquid coolant to maintain a constant temperature in the engine, 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; shutting off access to the radiator. This gets the coolant hot so that the engine warms up. Once it reaches the right temperature, your GMC Sierra 2500 thermostat then opens up and allows the coolant into the radiator. Now your coolant gets cooled as it recirculates through your GMC Sierra 2500 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.
