What Thermostats does for your vehicle.

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 cycles the coolant through the engine block and gets it hot. Once it reaches an optimal operating temperature, your GMC R1500 Suburban thermostat responds by directing coolant to the radiator. Now your coolant is part of a constant cycle in your GMC R1500 Suburban engine that keeps 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.
