For the proper functioning of the car engine, it must work at a certain temperature - from 115 to 135 C. The radiator is a metal component that acts as a heat exchanger, cooling the liquid circulating in cars with water cooling.
The liquid that passes through the internal pipelines of the engine absorbs the heat generated during fuel combustion. When the radiator is reached, the temperature is reduced by a fan and the outside air entering the car. After cooling, the material returns and the process repeats.
The liquid circulating in the engine is a mixture of water and a special additive, its function is to increase the temperature at which the liquid begins to boil. Without this combination, this would have happened at 100 degrees, which is well below the range recommended for vehicle operation.
