Tosol and antifreeze: What is the difference, is it easy to mix

The coolant is a chemical that is used in the engine cooling system, and characterized by improved freezing and boiling indicators, which allows to operate the car at any outdoor air temperature. Traditionally, all cooling fluids are called toosol, which is not entirely correct, since, despite the identity of the main components, antifreeze and Tosol differ in composition, and this is noticeably reflected in their operational qualities.

What is the difference between Tosol and Antifreeze

At the heart of all cooling fluids for cars lies machine of ethylene glycol and distilled waterIt causes their basic properties - a low freezing threshold and a boiling point of about 100 ° C. The main difference is the set of additives:

1. Tosol - type of coolant made by domestic producers according to traditional technology. It contains ethylene glycol and water with additives inorganic acids. The liquid is intended for cooling systems of domestic cars and loses properties after heating to 105 o C.

2. Antifreeze - Liquid made by foreign manufacturers for carboxylate technology. In addition to water and ethylene glycol, it includes additives based on salts of organic acids. In comparison with Tosol, it has elevated anti-corrosion, anticavitational and antipine properties. Successfully applied in cooling systems of both foreign and domestic cars.

It is impossible to distinguish antifreeze from Tosol on visual features. Some motorists have the erroneous view that Tosol is only a light blue shade, although it can be painted in dark blue, green, and even pink color. To do this, pay attention to the liquid producer: if it is released in Russia, then the carboxylate does not have to do.

The difference is determined after a thorough study of the composition. Tosuola contains nitrates, phosphates, silicates, borats and amines, and in antifreeze - additives from organic acid salts. Also, fluids differ in the boiling point: domestic boils after 105 o C, and carboxylate - after 115 o C. Tosola use - up to 40 thousand km run, while antifreeze can be used Without replacement up to 240 thousand km.

Advantages of applying antifreeze

Most motorists are preferred by antifreeze when choosing a coolant, based on the following reasons:

1. Increased cooling efficiencycaused by a more advanced additive composition. Antifreeze creates a protective layer only in those areas that have undergone corrosion.
2. The possibility of long-term operation Conservation of all major properties.
3. Good protection of aluminum parts High temperature cooling systems.
4. Water pump work occurs in gentle modethat is achieved by the use of carboxylates that protect it from hydrowards at cavitation.
5. Chemical inertnessThrough which new compounds are not formed in the cooling system, metallic, rubber and plastic surfaces are not damaged.

Is it possible to mix toosol and antifreeze, what will happen if mixed?

Both liquids - Tosol and antifreeze are made according to different technologies, and it is impossible to mix them. If the car was operated with Tosol, and its owner decided to switch to antifreeze, before the new fill, the cooling system is completely cleaned From traces of an old coolant.

When mixing antifreeze and antifreeze between additives, a chemical reaction occurs, as a result of which some compounds are folded with falling into the precipitate, which are able to score channels and the cooling system ducts. This will lead to the engine overheating and the subsequent expensive repair due to oil recalculation due to the occurrence of piston rings.

Antifreeze have a different composition and are divided into mineral (class G11), organic (G12), and elevords (G12 ++, G13). The difference between them is addresses:

1. Tosol belongs to mineral antifreeze, having a period of operation of 50 thousand km or 2 years of use.
2. Organic can be operated up to 5 years or 250 thousand km of mileage.
3. The debris can be combined with any other cooling fluids, and without concerning to tosses to new engines.

Is it possible to add water to antifreeze and toxol

Mixing antifreeze and antiframe with distilled water is permissible, since it is about 70% in the coolant. But the change in concentration changes their properties in the direction of the deterioration of the freezing threshold that with severe frosts may cause breakdowns in the form of a broken engine, radiators, and damaged pipes.

Not even frozen, and the crystallizable antifreeze is able to cause leak radiator. The addition of water can be justified only in the case of its evaporation, which changes the composition of the fluid towards increasing the density. It should be done, pre-draining antifreeze from the engine to the container so that after mixing, pour back to the system.

What does the color of the coolant mean

Tosol or antifreeze should be applied based on the features of the cooling system of a particular car, since different manufacturers of auto use various materials for its manufacture:

1. Red antifreeze Made for use in radiators consisting of brass or copper.
2. Green antifreeze Suitable radiators consisting of aluminum and alloys based on it.
3. Tosol It is better to use on domestic cars with outdated cast iron engines.

If, during operation, the coolant has acquired a brown or rusty shade - this indicates that its properties are lost, and the rust is not controlled by additives inhibitors, the quality of the engine cooling is worse. For the maximum long life of Tosola or antifreeze, you need to follow the recommendations of the manufacturer's plant, and fill the liquid that is specified in the vehicle operating manual.
