Chevrolet R20 Thermostats

Keeping your R20 in top shape is your top priority.

The vehicle in your driveway is head and shoulders above the rest compared to all the other vehicles in today's marketplace. You purchased your R20 because its dependability and value appealed to your senses; so why would you settle for second best when it comes to superior quality auto parts? Your Chevrolet dealership isn't the only place to find genuine or original equipment quality repair parts to fix your R20. Obviously, you didn't buy your R20 unless you understood you would be getting performance and good looks both impeccably combined into one car, truck, or SUV.

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 cycles the coolant through the engine block and gets it hot. Once it reaches an ideal temperature, your Chevrolet R20 thermostat then opens up and allows the coolant into the radiator. Now your coolant gets cooled as it recirculates through your Chevrolet R20 engine; keeping it within a specific range of temperatures that are determined for the engine to achieve the best balance between power, fuel efficiency, and emissions... all thanks to the thermostat.

We've got what you are looking for.
