Surfing the Internet The 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, the 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 automobiles, namely liquid cooling and air-cooling. Liquid cooling is used by most 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 maintains an optimum engine temperature. However, the air-cooling system is only feasible for small vehicles and equipment, as air-cooled engines do not operate at consistent temperatures and command extensive use of aluminum to disperse heat.
