Great cars and trucks like your FM350 need great parts.

Obviously, you bought your FM350 because you knew that you wanted horsepower and great value both rolled up into one car, truck, or SUV. When your GMC FM350 left the factory, it was destined for a driver who values longevity in their automobile. It's not all the time that you realize that you have to buy a replacement Thermostats to fix your automobile. Car aficionados know that a brand you can trust is built into each GMC, and know that only the highest quality replacement FM350 parts will suffice when maintenance needs to be done.

The function and purpose of Thermostats.

Your car or truck has a liquid-cooled 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; bypassing the flow of coolant through your radiator. This gets the coolant hot so that the engine warms up. Once it reaches an optimal operating temperature, your GMC FM350 thermostat then opens up and allows the coolant into the radiator. Now your coolant gets cooled as it recirculates through your GMC FM350 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.

Good products, great prices, the best people.
