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 cycles the coolant through the engine block and gets it hot. Once it reaches an ideal temperature, your GMC K25/K2500 Suburban thermostat then opens up and allows the coolant into the radiator. Now your coolant is part of a constant cycle in your GMC K25/K2500 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.

There's no reason to delay... checkout is simple and easy.
