GMC Syclone Thermostats

You enjoy taking care of your Syclone.

Obviously, you didn't buy your Syclone unless you wanted to buy performance and rugged design both rolled up into one vehicle. You purchased your Syclone because its dependability and longevity agreed with your nature; so why would you settle for second rate when it comes to the highest quality auto parts? Car aficionados appreciate the strong looks built into each GMC, and understand that only the highest quality repair Syclone parts will suffice when repairs are needed. Your GMC dealership isn't the only place to buy genuine or original equipment quality parts to repair your Syclone.

What Thermostats does for your vehicle.

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 gets the coolant hot so that the engine warms up. Once it reaches the right temperature, your GMC Syclone thermostat responds by directing coolant to the radiator. Now your coolant is part of a constant cycle in your GMC Syclone engine that keeps it at a steady and controlled temperature ideal for engine performance... all thanks to the thermostat.

We've got what you are looking for.
