Automotive cooling system employs car radiator to release heat generated by the engine. Its primary role is to keep the heat exchange process from overheating as the coolant absorbs excess heat and discharges into the radiator fins. Technologies are also used, such as a very thin aluminum or copper core that allows for an increase in surface area to maximize heat exchange. Today's radiators also feature trick add-ons like turbulators, which agitate the coolant as it flows and make it more efficient at transferring heat. This is very important for everyone who uses any type of vehicles from hatchback to heavy duty trucks it will enable better performance and engine life.
