When your GMC PM251 left the factory, it was destined for a driver who prioritizes longevity in their automobile. Make no mistake, you didn't buy your PM251 unless you wanted to buy horsepower and rugged design both rolled up into one automobile. The vehicle in your driveway is head and shoulders above the rest compared to all the other vehicles these days. Anyone who drives a GMC knows that when it comes to maintaining their car, truck, or SUV only the most superior replacement parts will do.
Your car or truck has a liquid-cooled 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 gets the coolant hot so that the engine warms up. Once it reaches an ideal temperature, your GMC PM251 thermostat then opens up and allows the coolant into the radiator. Now your coolant gets cooled as it recirculates through your GMC PM251 engine; keeping 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.
