Normally they come with a core made of fins and tubes, the inlet and outlet tanks, Legacy Radiators a generally made of aluminum core and plastic or aluminum tanks but copper /brass are also used. Located in front area of the vehicle the radiator effectively transfers heat from the engine coolant to the air thus providing best system output. Performance radiators are better than production units in that they build lightweight aluminum construction to complement the design with better thermal and fluid dynamics. These radiators incorporate larger tubes and higher fin density, which allows for the cooling capacity of the coolant and the heat transfer area to be greatly improved, therefore allowing for a cooler engine to be achieved.
