GMC C25 Thermostats

Why you drive your C25.

When your GMC C25 was born, it was destined for a driver who values longevity in their automobile. The vehicle in your driveway is head and shoulders above the rest compared to all the other cars, trucks, and SUVs on the road today. You purchased your C25 because its dependability and longevity appealed to your senses; so why would you be okay with second rate when it comes to superior quality auto parts? Anyone who drives a GMC knows that when it comes to maintaining their vehicle only the absolute best replacement parts will do.

Don't go too long without fixing your Thermostats... here's why.

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; bypassing the flow of coolant through your radiator. This cycles the coolant through the engine block and gets it hot. Once it reaches an ideal temperature, your GMC C25 thermostat then opens up and allows the coolant into the radiator. Now your coolant gets cooled as it recirculates through your GMC C25 engine; keeping it at a steady and controlled temperature ideal for engine performance... all thanks to the thermostat.
