Car Cooling System

The cooling system is a set of components that enables the flow of liquid coolant to the passages in the engine block and head so as to absorb combustion heat. The heated fluid will then return to the radiator through a rubber hose, for cooling. As the heated fluid (hot water) flows into the radiator through the thin tubes, it gets cooled by an air stream.

Modern internal combustion engines cooled with both water and air, but some engine uses either air or liquid to remove the waste heat from the engine. Special purpose or small engines are cooled using air from the atmosphere, which makes the system lightweight and relatively less complex. While in some engines, heat is transferred from a closed loop of water to the radiator where the cooling is achieved.
