Automotive The cooling system forms an intrinsic part of an automobile engine. It performs multitude of functions such as removing excess heat from the engine, maintaining efficient temperature and allowing engine to perform its task within a short span of time. Ideally, automobile cooling system keeps the engine running at an optimum temperature whatever the operating conditions are. Automobile Cooling System consists of components or equipment installed in vehicles for removing heat from all the moving parts so that they can work suitably without melting, seizing and overheating. More specifically, automotive cooling system makes use of coolant, lubricating oil and fan to maintain and regulate the temperature of other parts of an engine. Basically, there are two types of automobile cooling systems, which are widely used by the automobiles namely: liquid cooling and air-cooling. Liquid cooling is one of the sought after system used by most of the vehicles today while air-cooling is mostly used by airplanes, motorcycles and lawn mowers. The liquid-cooling system for automobiles offers the most positive cooling and it maintains an optimum engine temperature. While air cooling system is feasible for only small vehicles and equipment, as air-cooled engines do not operate at consistent temperature and command extensive use of aluminum to disperse heat.
