Buick Rainier Radiator

Great cars and trucks like your Rainier need great parts.

Obviously, you bought your Rainier because you knew that you wanted efficiency and fun both rolled up into one vehicle. You purchased your Rainier because its dependability and a trusted name appealed to your senses; so why would you be okay with anything but the best when it comes to superior quality auto parts? The vehicle in your driveway symbolizes the best in class when it comes to all the cars, trucks, and SUVs these days. It's not all the time that you discover you need a replacement Radiator to repair your vehicle.

Why Radiator replacement is so important.

Your vehicle uses liquid coolant to maintain a constant temperature in the engine, and the cooling liquid needs to travel through the radiator before it can do its job. The heat produced by the combustion process gets absorbed by an ethylene glycol based liquid, and that coolant has to enter your Buick Rainier radiator through the top and flow down to the bottom so that it can reduce its temperature. When it leaves the radiator and re-enters the engine, it can now absorb more heat. Your Buick Rainier depends on the constant recirculation of cooling liquid so that it can stay within the prescribed operating temperature.
