Cooling water is considered one of the most important things that preserve the safety of the car and its passengers, especially in the summer, with temperatures increasing significantly in most of the Arab countries.
Therefore, the car owner must pay great attention to the refrigeration cycle in the cars and choose the water for the refrigeration according to the specifications, especially as some use ordinary water without using the original cooling water in the car and there is a big difference between the two types.
And workers in the field of car maintenance confirm that the car engine is operating in its ideal condition with a temperature ranging between 80 and 90 degrees Celsius while the engine temperature rises in modern cars until it reaches 105 engines.
And in the case of using regular water, especially with modern cars, it evaporates at 100 degrees, which will cause the accumulation of salts and the formation of rust in the cooling cycle of the vehicle while increasing the internal pressure on the water hoses as well.
While cooling water provides a greater opportunity for the engine to work, as it reaches a boiling point, but at 135 degrees, and it is free from distilled water and a substance called ethylene glycol, as well as materials against rust and corrosion.
This combination enables the engine to cool due to the boiling difference between it and normal water, in addition to the ethylene glycol protects the internal parts of the engine's cooling water from corrosion due to its light viscosity.
