Why you need a coolant
Why you need a coolant
Radiator or coolant, refrigerant,antifreeze - all these are names very important and necessary for any motorist fluid. It does not freeze to -40 ° C-60 ° C, has a boiling point above 108 ° C and performs a number of functions necessary to maintain the car in a working condition.
Instructions
1
Cooling the car engine is one of themain functions of the radiator fluid. The antifreeze or antifreeze maintains the operating temperature of the engine, which is 90-110 ° C above zero, thereby preventing it from overheating. The low temperature is maintained by means of a radiator - a set of cooling tubes.
2
Heated driver in cold weather. When the cooling system, one of the main elements of which is the radiator liquid, generates heat, which enters the passenger compartment and heats the people in it.
3
Protection of the cooling system against cavitation, corrosion,and the harmful effects of nitrites and phosphates that are contained in water. In addition, the cooling liquid is a protective agent against the swelling of the rubber elements of the cooling system, and also helps maintain their elasticity.
4
Coolant also has lubricatingproperties. Moreover, the assumption that special additives are added to antifreeze or antifreeze to add lubricating properties are incorrect. Such properties are realized due to the oily consistency of its main components - ethylene glycol or propylene glycol.
5
Antifreeze or antifreeze has a highhygroscopicity. This property means the ability of the coolant to absorb water. Over time, antifreeze or antifreeze, which are in the engine cooling system of the car, diluted with water and lose their useful properties. However, in order for the cooling liquid to perform all its functions and ensure the smooth operation of the car in any weather, it must be changed at least once every 2 years or after a certain mileage, on the recommendation of the car manufacturer.
