Although gasoline engines have improved a lot, they are still not very efficient at turning chemical energy into mechanical power. 70% of the energy in the gasoline is converted into heat. Cooling system is to keep the engine from overheating by transferring this heat to the air.
There are two types of automobile cooling systems
Liquid cooling and air-cooling
The key components used in a cooling system are pressure cap, heater hoses, thermostat, heater core, reserve tank, lower hose, transmission cooler, water pump, fan, radiator and upper house. The cooling system of a vehicle operates or functions by directing liquid coolant via passages in the engine block and heads. After that the liquid coolant which flows through passages absorbs the heat from an engine. Then this fluid passes through a rubber hose to reach to the radiator. At this stage the hot liquid is cooled by air stream entering the engine compartment via grills. Once it gets cooled, then it goes back to engine and same process repeats again. Removing excess heat from the engine, maintaining efficient temperature.
Cooling system gaskets
Cooling System Gaskets are seals or packing especially designed for joining or sealing the matched components or pipe joints in an automobile cooling system with the main purpose of stopping the escape of a gas or liquid. Usually, cooling system gaskets are made up of soft sheet metal, which are stamped with ridges that enclose all leak points. Even steel, copper and asbestos can also be used for making cooling system gaskets. The main function of cooling system gaskets is to prevent fluid or gas leaks by offering a close or tight barrier between two mating surfaces.

Water cooling systems
Water Cooling Systems includes various components, equipment and accessories that are explicitly used for cooling internal combustion engines in automobiles. Automobile engine cooling systems basically need water and other anti-freeze mixtures to lower down the shooting temperature of the engine.

How does the thermostat in a car's cooling system work?
Any liquid-cooled car engine has a small device called the thermostat that sits between the engine and the radiator. The thermostat in most cars is about 2 inches (5 cm) in diameter. Its job is to block the flow of coolant to the radiator until the engine has warmed up. When the engine is cold, no coolant flows through the engine. Once the engine reaches its operating temperature generally about 200 degrees F, 95 degrees C, the thermostat opens. By letting the engine warm up as quickly as possible, the thermostat reduces engine wear, deposits and emissions. The cylinder is filled with a wax that begins to melt at perhaps 180 degrees F different thermostats open at different temperatures, but 180 F/82 C is a common temperature. A rod connected to the valve presses into this wax. When the wax melts, it expands significantly and pushes the rod out of the cylinder, opening the valve
