The difference between antifreeze and antifreeze.

Any car owner wants his "iron horse" to work for decades. That is why we listen to the sound of the engine, try to refuel at proven gas stations, buy high-quality oils and antifreeze. Although for a novice car enthusiast, choosing many means to improve the performance of a car is a long journey of trial and error. One of the problems can be the choice between antifreeze and antifreeze, because for uninitiated citizens these two coolants are one and the same. Let's try to find out if they really are so similar.


Antifreeze refers to all coolants without exception, regardless of where and when they are released.

Antifreeze is a type of antifreeze produced in the USSR. Due to the fact that there was no alternative to antifreeze, very soon the name of the trademark became a household name and for a long time other antifreezes were also called so, which fell on the Soviet, and then the Russian market. In fact, TOSOL is an abbreviation that stands for "the technology of organic synthesis of a separate laboratory."


The composition of antifreeze, like any other coolant, contains ethylene glycol and water. In antifreeze, additives are used based on salts of inorganic acids, for example, phosphates, silicates, nitrates and nitrites.

The antifreeze also contains ethylene glycol and water, glycerin, propylene glycol and alcohol. In other words, antifreeze is ethylene glycol (or propylene glycol), water, and additives. It is the additives that are especially valuable in the composition, since they increase the anti-corrosion, anti-cavitation, anti-foam capabilities of the antifreeze. The antifreeze contains additives based on organic acid salts.

Performance characteristics

Thanks to antifreeze, a protective layer is formed on the metal surface, as a rule, its thickness does not exceed 0.5 mm, but the disadvantage of such protection is low heat transfer. Because of this, fuel consumption increases, and the engine itself wears out faster. Antifreeze loses its cooling capacity after 30-40 thousand kilometers. Due to the fact that antifreeze contains inorganic salts such as phosphates and silicates, gels and deposits may form, which can lead to clogging of the radiator. At high temperatures, antifreeze works in the system up to a limit of 105 degrees.

Antifreeze forms a protective layer only on walls subject to corrosion, due to the fact that there is no protective layer on the rest of the metal, the heat transfer remains intact. This coolant does not lose its properties when a passenger car has traveled more than 250 thousand km. Due to the fact that organic salts are used in carboxylate liquids, no precipitation is formed. Antifreeze boils at 115 degrees.


  1. Antifreeze is a common name for all coolants, antifreeze is a brand of antifreeze developed in the Soviet Union.
  2. Additives in the composition of antifreeze are inorganic salts, and in the composition of antifreeze - organic.
  3. Antifreeze forms a protective metal layer of 0.5 mm, while impairing heat transfer. Antifreeze will form a protective layer only in areas of corrosion.
  4. Antifreeze loses its cooling capacity after 30-40 thousand km, and antifreeze after 250 thousand km.
  5. Antifreeze is less resistant to high temperatures, and antifreeze boils at a temperature of 115 degrees.
