Radiator or coolant, coolant, antifreeze - all these are the names of a very important and necessary fluid for any motorist. It does not freeze down to -40 ° C-60 ° C, has a boiling point above 108 ° C and performs a number of functions necessary to keep the vehicle in good working order.
Instructions
Step 1
Cooling a car engine is one of the main functions of a radiator fluid. 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 pipes.
Step 2
Heating the driver in cold weather. During the operation of the cooling system, one of the main elements of which is the radiator fluid, heat is released, which enters the passenger compartment and heats the people in it.
Step 3
Protection of the cooling system against cavitation, corrosion, as well as the harmful effects of nitrites and phosphates, which are contained in the water. In addition, the coolant protects against swelling of the rubber elements of the cooling system, and also helps to maintain their elasticity.
Step 4
The coolant also has lubricating properties. Moreover, the assumptions that special additives are added to antifreeze or antifreeze to give lubricating properties are incorrect. Such properties are realized due to the oily consistency of its main components - ethylene glycol or propylene glycol.
Step 5
Antifreeze or antifreeze is highly hygroscopic. This property means the ability of the coolant to absorb water. Over time, antifreeze or antifreeze in the car's engine cooling system is diluted with water and loses its useful properties. However, in order for the coolant 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, as recommended by the car manufacturer.
