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; shutting off access to the radiator. This cycles the coolant through the engine block and gets it hot. Once it reaches an ideal temperature, your GMC Sierra 3500 Classic thermostat then opens up and allows the coolant into the radiator. Now your coolant is part of a constant cycle in your GMC Sierra 3500 Classic engine that keeps it within a specific range of temperatures that are ideal for engine performance... all thanks to the thermostat.
