Select Your VehicleWhile it may not be difficult to locate replacement parts for Buick vehicles, these days the necessity for nothing but the highest quality are required to repair your car or truck. Your Buick dealership isn't the only place to locate the best repair parts to fix your Riviera. You picked your Riviera because its reliability and economical pricing struck a chord inside you; so why would you settle for second rate when it comes to superior quality auto parts? Obviously, you bought your Riviera because you wanted to buy a variety of special features and American style both impeccably combined into one car, truck, or SUV.

The function and purpose of Thermostats.

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; bypassing the flow of coolant through your radiator. This gets the coolant hot so that the engine warms up. Once it reaches an ideal temperature, your Buick Riviera thermostat responds by directing coolant to the radiator. Now your coolant is part of a constant cycle in your Buick Riviera engine that keeps 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.

You've tried the rest, now try the best.

Don't let a broken Thermostats bring about the demise of your car, truck, or SUV, and don't risk lowering its resale value by buying anything but the highest quality repair parts.
