Antifreeze G-11 and G-12 - chemical compound with the use of aqueous solution designed to cool the engine at maximum loads. Its use directly depends on the cooling system and motor configuration.
For old models, release until 1996 inclusive, ordinary antifreeze, without sparing formulas and modern additives, are quite suitable for banal ovens. For subsequent brands of domestic and foreign cars, more modern cooling fluids are needed, which are capable of responding not only to modern norms of frost resistance and boiling, but also protection against different system sediments.
In this article, we will get acquainted with the main types of antifreeze (G-11, G-12, G-12 +, G-13), their properties, what is their difference, and can I mix these antifreeze among themselves?
In this regard, there is a generally accepted classification of antifreeze, which makes it easy to navigate the world of cooling liquids.
Antifreeze classification:
- antfriz G-11 - The basis of silicates and inorganic additives. It is interesting to know that the ethyl alcohol, which underlies the domestic antifreeze, also corresponds to the G-11 class, therefore the statement that antifreeze and Tosol is the same, it is possible to accept truth with confidence. The main use of antifreeze G-11 is predetermined in old cars, which differ from modern models with a large amount of cooling system. As mentioned more than once, the whole class of these antifreezes creates a special protective film, which is directed exclusively to protect against the effects of the aggressive medium inside the machine. The negativeness of such protection is that the thermal conductivity is significantly reduced, that is why modern cooling systems on new cars cannot use such coolars, their thin channels of the cooling system will immediately bother with film formation and will not be able to provide sufficient circulation of antifreeze. The average booster temperature at the G-11 class is at 105 degrees Celsius. Optimal mileageThe manufacturer declared, ranges from 50,000 to 80,000 kilometers, which is on average for 2-3 years with a gentle operation of the machine.
- antfriz G-12 - compounds of propylene glycol with universal balanced additive packages, mainly made of carboxylate compounds of organic origin. All Class G-12 antifreeze are shown to use on modern cars With high-breasted engines, which can be attributed to the class of thermally loaded. The average boiling point is 115 - 120 degrees above zero, although some analogues of G-12, can and overcome this threshold. The pressure in the cooling system directly affects the booster temperature of antifreeze in this class, therefore, depending on the modification of the machine, the coolant operations can be varied. Protective additives from corrosion and other deposits in the system work point. They are like a doctor, choose the place of illness and eliminate it by entering into a reaction with a chemical compound. The viscosity of such antifreezes is higher, and harmful components are reduced, unlike the entire class of the G-11 coolant. G-12 or red antifreezes, as they are also called, have a extended service life without loss of performance, which can be correlated from five years or an approximate mileage of 250,000 kilometers.
- Antfriz G-12 + -the next generation, with a more improved and adapted formula. Chemistry of this class considers less harmful and for humans and for ambient. The G-12 + is also the same as an organic organic, arched by more modern additives. The rest of the differences between the G-12 and G-12 + were not detected, although many autocontracens declare this class of antifreeze for their cars.
- antfriz G-13 - This is a new variant of coolant based on propylene glycol, although this statement is controversial. It was previously apparent to assume that all three of the previous class were at their own ethylene glycol. Indeed, before the development of new propylene technology, it was exactly the case, but with the advent of the synthesis of propylene, almost all classes G-12 and G-12 + are also belonging to the component G-13, which is designed to cool the engines of sports cars, motorcycles and others similar in characteristics power aggregatesoperating on extreme loads in extreme conditions.
The difference between antifreeze G-11 and G-12?
You can mix the homogeneous bases among themselves and that, it is desirable from one manufacturer to prevent conflict additives. In other words, it is necessary to read the label and make sure that for a mixture, both antifreeze have the same basis of ethylene glycol or propylene glycol. If you mix the two of these components with each other, then with a 100% warranty, the mixture or foam, or will give a precipitate in expansion tankSometimes flakes can be on its surface.
To the question - is it possible to mix antifreeze G-11 and G-12, the response to the surface: under any circumstances do not interfere with G-11 and G-12 !!! Even with their identical basis. The difference in additives will also give a precipitate, flakes, rusty shade or at best will reduce the life of G-12.
For mixing can be in emergency cases Send the G-11 and G-12 + systems, the latter has a more neutral formula. In this case, the nuclear cocktail should be replaced at the first opportunity, pre-flushing the cooling system several times with distilled water or special tool. It seems that the answer to the question is what the difference between the antifreeges G-11 and G-12, and is it possible to mix them - this is exhaustive.
The main thing is to act according to the instructions given by the automaker, then many problems will arrive at you, and your car.
Antifreeze is a liquid that is designed to cool the engine of the car, and maintaining the permanent operating temperature.
Many car owners, when choosing antifreeze, do not pay attention to its type, brand, and composition, believing that they are all the same. But it's far wrong. If the liquid is not intended for operation in this form of the cooling system, this is fraught with serious consequences, up to the failure of the engine itself.
In addition, it is undesirable to use poor-quality toosol or antifreeze with an expired shelf life, mix different types Liquids with not the same chemical composition and different manufacturers. Such exploitation will negatively affect the engine operation and create additional problems. Cooling fluids have their markings, which indicates certain properties of the product, and compatibility with various cooling systems. Antifreeze are divided into two main categories: G11 and G12.
The liquid in which ethylene glycol enters, has a more common name " tosol", It has been produced for several decades, and is used mainly in cars with carburetor type of engines. The advantages of G11 are in its, relatively, small cost. Such a liquid, when working in the cooling system, forms a protective layer, which protects the system from corrosion. Antifreezes of this type have many drawbacks:
- The layer formed during the circulation of the cooler prevents its heat transfer that often leads to a set of high, limit, temperature, and engine overheating.
- The presence of chemical components and compounds (phosphates, silicates, etc.), which contribute to the formation of scale, in the cooling system.
- The speed of evaporation when working at high temperatures, it is necessary to often add a new liquid.
- Almost, complete absence of active auxiliary additives necessary for the prevention of corrosion and increase the quality properties of the refrigerant.
- Fast loss of characteristic qualities of the cooler (after a few months), the liquid becomes similar, according to the properties, on ordinary water, except that it does not freeze in the winter.
This is a more modern version of the fluid, for the cooling system, which is excellent for various types of engines (injection, forced, turbocharged, and others) with a higher operating temperature than the carburetor.
Antifreeze is made of the same ethylene glycol, but with the addition of a large number of active additives and components. The minus antifreeze of the G12 brand is high intimacy for the environment, as well as in G 11.
Preferential characteristics G12:
- Forms a protective layer only on corrosion areas, which gives the optimal heat removal, and prevents overheating in the system.
- Throughout the service life (up to 5 years), retains its active properties.
- Ability to use B. modern systems, with elevated temperature ranges.
- Low evaporation, and frosted temperature.
Antifreeze of this category is considered the most optimal component of the cooling system, as there are no chemical compounds such as nitrites, borates, phosphates that have a harmful effect on the engine. 
In addition, some brands of liquids of this category contain fluorescent components, which allows you to visually detect leakage of fluid in the dark.
Antifreeze, regardless of its brand, can be different in its composition. Mix liquid, even if they are one category, but different manufacturers are not recommended. This can lead to the loss of high-quality fluid properties.
Categorically it is not recommended to mix G11 and G12This can lead to deposits, from washing the entire cooling system, before the failure of the engine. If an urgent need arose to achieve a liquid into the system, and at hand there is no appropriate brand, then it is permissible to mix the liquids of the same manufacturer, although, after that, the flushing system will not be superfluous.
Finally, look interesting video On the classification of antifreezes:
The car when it is involved, constantly resides in motion. And it concerns this, not only movement on the road, but also the movements of its individual parts that are inside. And any friction, as you know, leads to heating. So, we need to take care of the high-quality cooling of the motor.
For this, special substances under the name of antifreeze that have low temperature Viscosity. This is advantageously different from simple water, which can damage individual components, if the temperature is less than zero.
Tosol - last century, now modern motors cool antifreeze
Until recently, all fluids that are designed to cool the engine were called "Tosol", but now people began to distinguish antifreeze on different types. In general, there are variants on saline and on an acid-based basis. And so that motorists do not confuse them among themselves, they are all painted in different colors. In the case of salt solutions, we can see the blue or green shade, while the acidic options have a characteristic red color.
The choice of a particular type of antifreeze depends on what materials the manufacturer worked when creating a motor cooling system.
Antifreeze G11 - almost toosol, only with additives
The liquid component of antifreeze is represented by a substance called ethylene or polypropylene glycol.
Since the first of these two components has elevated level Toxicity, most manufacturers stop their choice in the second version. So, it is impossible to mix different types of liquids. And, if necessary, replacing antifreeze, it must be completely merged from the system, replacing the new one.
G11 and G12. Features and differences
Some of the most popular types of antifreeze, which are common in our country, are considered G11 and G12. They are quite different among themselves, which indicates the inadmissibility of mixing them. And today we learn what is the difference between antifreeze G11 from G12?
Antifreeze differ significantly in color
So, in front of many drivers the question arises, choose them G11 or G12? So, G12 is a red liquid (in some cases - yellow), which is a carboxylate antifreeze. This substance is characterized by a local action, due to which, in the event of an occurrence in the system of corrosive lesion, additives can help localize it in their place, not allowing to spread further.
Video about the main differences of these types
Very interesting video about what the types of antifreeze, the main production technologies, the functional differences G11 from G12, also considered the type of antifreeze G12 ++.
Thus, antifreeze can serve you long enough, in some cases, much longer than five years. And then, his replacement is appropriate only when the additives begin to exhaust their properties.
As for the antifreeze denoted by the G11 index, it is represented by a substance of the type of silicate component. It can have almost any shade. It can be green or blue, yellow or orange, and sometimes even red. But, nevertheless, the red color of this substance is almost never found.
It is this substance in our country to be appointed to Tosol, as it is its almost complete analogue. This liquid affects the system and its walls, covering them with a special protective layer. But, the service life of this substance is not very big - only three years.
Replacing antifreeze G11
If you used only one of these types of antifreeze, then you need to change it to another with some reservations. We are talking about the fact that after G11 remains an old protective film, which does not allow the antifreeze with due efficiency. In addition, it will be necessary to change it in three years of operation of the car. But Tosol, which is filled after the G12 brand, immediately stops the impact of the latter on the wall walls. Thus, you need to use the same coolant brand continuously, and mixing them is prohibited at all.
Exceptions
But, there are exceptions. So, it is possible to mix with Tosol antifreeze called G12 +, which has practically the same properties as G12. In this situation, the only negative point will be only that the validity of antifreeze will suffer, decreasing to the mark in three years.
Need to take into account the composition of liquids
In general, you do not need to fully rely on color markingAs adopted in the medium of domestic motorists. Optimally, if you read the composition of antifreeze G11 or G12 carefully, focusing on the presence of the same components in the composition.
What kind of Tosol belongs to?
As we said, Tososol's name has become a nominal. But, what specific type of antifreeze is this product? Thus, a substance called Tosol A-40, if it is prepared correctly, must repeat the composition G11 with all its components and additives. However, many experts do not recommend using modern toosol in cars.
Disadvantages of Tosla
The reason for this lies in the fact that in the specified substance there are practically no inhibitors of foreign processes of foreign production, which would be able to provide all protective properties. In addition, many minor firms that do not have access to the correct recipe, as well as to the production of Tosol today necessary components. As a result, many studies have shown that a significant part of products with the Tosol title, which is currently represented in the market, is nothing more than a mixture of ethylene glycol, ordinary water and a dye of one or another color, most often - blue.
About mixing antifreeze.
Many do not know whether antifreeze can be mixed with G11 and G12. Despite the fact that the same substances are included in antifreezes, some components may differ, which makes a mixture unsuitable for mixing among themselves.
Also, you should not try this cooling fluid to taste, because it is capable of damage to health, including poisoning. Antifreeze differences are in the presence of lubricating components and substances with anti-corrosion properties. They are also distinguished by aggressiveness to the glands, gaskets and pipes, freezing temperature and boiling point.
Possible problems when mixing antifreeze
Color features are provided with just dyes, which are added to the composition. Ideally, antifreeze of different manufacturers, but one color, you can safely mix each other. And this is so if we are talking about proven brands. Exceptions are only fakes, when colors are determined chaotic, depending on the desire of buyers, not the characteristics of the composition. If the compositions are not similar, that is, the chance that this substance will foam and even falls into the sediment.
If you are critical of the possibility of further mixing antifreeze, you need to always buy G12 or G12 +, as they have a property to respond normally to any other substances that fill them, even in the case of G11.
Similar liquids, almost always, have a bright red color that distinguishes them.
And, of course, do not forget what recommendations are given by the manufacturer of your car, since the difference between the antifreeze G11 from G12 is quite significant.
For example, Tosol will suit not all cars, since its composition includes some aggressive components that may damage new foreign cars, while domestic cars Pretty easily tolerate it. Moreover, Tosol and was in the past century, designed for cars produced under the VAZ brand.
Pretty popularities in our country certain types of antifreeze, which have some differences. Different base is that the difference between antifreeze G11 and G12, designated in the form of admission from Volkswagen.
The deposit of uninterrupted operation in the engine cooling system is high-quality antifreeze. It is incorrect to think that the requirements are not very big to this product: in winter it will not freeze, and in the heat will not boil.
But, after all, not to spend money on the replacement of parts or complete repair, choose this product very carefully and demanding.
The original name is Antifreeze, denotes a "non-freezing", glycolic basis: with ethylene glycol or propylene glycol and improvement additives. Ethylene glycol consists of two-heed alcohol. The oil consistency fluid boils when the plus is two hundred degrees, and freezes if minus twelve.
What is part of:
- ninety percent - ethylene glycol;
- five to seven percent - additives;
- three five percent - water.
Characteristics of the cooler G11
G11 (Tosol) is used in old machines, with a large volume of the cooling system. The entire system is protected by a special film that prevents corrosion of some details. Although there are certain disadvantages associated with a decrease in thermal conductivity. Modern production machines such a system is not suitable. The deterioration of the engine of such a car is very likely.
Antifreeze G11 differs from G12 both in color and in composition. Ethylene glycol has blue colour, and carboxylate is another chemical having a red color and no silicates. Its national standards are available for each country, they usually have already outdated. Today there is no identical standard that all antifreeze would fit.
Characteristics and features:
- used in almost all cars;
- density more than a thousand kg / m 3;
- temperature mode one hundred ten degrees;
- reliable protection of the cooling system;
- inhibitors increase the service life.
Traditional technology is used in class G11. The difference in color between G11 and G12 significant and there are very big differences, even toxicity. So, G 12 is a red or yellow liquid, carboxylate antifreeze. But G11 is orange, yellow, blue or green.
Class 12 cooler and its distinctive features
Antifreeze class G12 - next stage in the development of such a product. Some flaws technological process Manufacturers removed when organic acids were mastered. Now carboxylic acid is used and called their carboxylate. They differ in that there is no protective layer over the entire surface.
Positive moments:
- the level of thermal return is much higher;
- shopping and destruction in the system is not, the abrasive does not appear;
- the use has increased for several years;
- high-level protective functions;
- accessibility and availability in all stores.
The composition of antifreeze G12 includes organic additives and ethylene glycol. Easier tolerate high temperatures, which is very important for modern motors From aluminum.
The color does not characterize the quality and productivity of this product. Choose such a product by shade will be an incorrect and rapid solution.
Lots of modern engines We only need organic antifreeges. Long Life (G12, G12 +) - are organic. The newest additives created in a completely different principle of protection of metals from corrosion. These additives of the new generation, create obstacles in the formation of oxide and make their functions much longer. There are some restrictions in such an option - you can not use with a yellow metal, which is very important for buyers.
Important facts
It is impossible to mix antifreeze G11 with G12, even if similar or almost the same substances. Nevertheless, there are components that are very different and make a mixture impossible for mixing. Differences may be in the presence of lubricating components and substances with anti-corrosion properties.
Dyes simply provide antifreeze color personality, they are added to the composition. If the goods OT. miscellaneous manufacturerBut, the same shade, there is an opportunity to mix it with each other. Only fakes have exceptions in this regard, where the definitions of colors are chaotically and without features in the composition. If there is such a need for mixing antifreeze, you need to buy G12 or G12 +. They have properties of a normal reaction to any other substances.
What is G12?
- ninety percent - ductomic alcohol ethylene glycol;
- five percent - distilled water;
- at least five percent of the additive package;
- dye
So what is the difference
The difference between G12 and G12 + is very small. The G12 + class is combined with many compositions and implies the use of different hybrid production technologies. The combination of silicate with carboxylate makes many problems. G12 and G11 are mixed, although this option is still not recommended by the manufacturer.
The correct replacement of antifreeze is fully related to the technical characteristics of auto and specificity. vehicle. After selecting a specific option, it is necessary to monitor its color and condition.. If the color change was noticed, there is a loss of the protective property and then the coolant replacement is necessary. Always carefully choose the goods to avoid fakes, see the country of manufacturer and barcode on each purchase. It depends on the serviceability of your car, its performance and worniness of all parts.
