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 cycles the coolant through the engine block and gets it hot. Once it reaches an optimal operating temperature, your GMC R2500 Suburban thermostat then opens up and allows the coolant into the radiator. Now your coolant is part of a constant cycle in your GMC R2500 Suburban engine that keeps it within a specific range of temperatures that are ideal for engine performance... all thanks to the thermostat.

You've tried the rest, now try the best.
