Why Thermostats replacement is so important.

Your car or truck has a water-cooled motor, 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 gets the coolant hot so that the engine warms up. Once it reaches the right temperature, your GMC Sierra 2500 HD thermostat then opens up and allows the coolant into the radiator. Now your coolant is part of a constant cycle in your GMC Sierra 2500 HD engine that keeps it at a steady and controlled temperature determined for the engine to achieve the best balance between power, fuel efficiency, and emissions... all thanks to the thermostat.
