The automotive radiator is a type of heat exchanger. It is designed to transfer heat, generated by the engine, from the coolant/ antifreeze to the surrounding air. Today most radiators are made of either copper and brass (older and more traditional style) or plastic and aluminum. Both construction styles are fully capable of doing its job; however they do have subtle advantages and disadvantages, we'd be happy to explain. Radiator related problems are normally leaks or overheating (lack of capacity to transfer heat) both problems are easily corrected.
