The function and purpose of Thermostats.

Your car or truck uses liquid coolant to maintain a constant temperature in the 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; shutting off access to the radiator. This gets the coolant hot so that the engine warms up. Once it reaches an ideal temperature, your GMC Sierra 3500 thermostat responds by directing coolant to the radiator. Now your coolant is part of a constant cycle in your GMC Sierra 3500 engine that keeps it at a steady and controlled temperature ideal for engine performance... all thanks to the thermostat.
