Buick Roadmaster Series 70 Thermostats

Your Roadmaster Series 70 is a prized possession.

You purchased your Roadmaster Series 70 because its reliability and a trusted name appealed to your senses; so why would you settle for second rate when it comes to the highest quality auto parts? The vehicle in your driveway is head and shoulders above the rest compared to all the other vehicles currently being driven today. Make no mistake, you didn't buy your Roadmaster Series 70 unless you understood you would be getting efficiency and American style both rolled up into one automobile. Car aficionados know that value is built into each Buick, and understand that only the best replacement Roadmaster Series 70 parts will suffice when repairs are needed.

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

Your car or truck uses liquid coolant to maintain a constant temperature in the 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; shutting off access to the radiator. This cycles the coolant through the engine block and gets it hot. Once it reaches an ideal temperature, your Buick Roadmaster Series 70 thermostat then opens up and allows the coolant into the radiator. Now your coolant gets cooled as it recirculates through your Buick Roadmaster Series 70 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.

The best parts are right around the corner.
