As you know, the engine generates a huge amount of heat during operation. In order not to overheat the block and parts of the crank mechanism, the internal combustion engine has channels for coolant. It is she who prevents the engine from overheating, which is fatal to the block and head. Indeed, at the slightest overheating, the cylinder head begins to “lead”. And not always it can be restored with a groove. In today's article, we will pay attention to antifreeze, in particular red.

Varieties

It is worth noting that G12 red antifreeze is not the only representative of coolants.

There are several groups in total:

• G11. These are domestic antifreezes and blue antifreezes. Used on cars until 1996.
• G12. Now this is the most common group of antifreezes, which is used by the world's leadingautomakers. The composition has a more gentle structure, and is also distinguished by the presence of carboxylate additives. It can be dyed not only red, but also lilac.
• G13. It is currently the most environmentally friendly coolant for internal combustion engines. Has excellent properties and characteristics. However, due to the high cost, it is not used as widely as the previous group. In addition, G13 type fluids are not designed for brass and copper radiators.

Composition

Regardless of type, any cooler has a homogeneous composition and similar technical characteristics. Antifreeze G12 red is no exception.

So, it is based on polypropylene glycol or ethylene, artificial dye and part of distilled water. Additionally, the cooler has an additive package:

• Anti-foam. Reduce the risk of foam formation in the expansion tank when fluid circulates in the system.
• Anti-corrosion. Prevent rusting of metal parts in the engine and radiator.
• Additives that protect rubber components. These include gaskets, pipes and hoses through which the radiator is connected to the expansion tank.

This is the main list of additives. In addition, there are a number of other additives designed to improve wear resistance and increase the life of the cooler. Thanks to them, the temperature indicators also increase. It is from the quantity, as well as the properties of the additives, that it depends which group this or that coolant belongs to. Yes, group 11has the lowest performance. The freezing temperature is not lower than -30 degrees Celsius, and the service life is not more than two years.

G12 Red Antifreeze has more advanced specifications. So, it works in the range from -45 to +110 degrees Celsius. The service life is about five years. Therefore, if the question arises of choosing blue antifreeze, or antifreeze from the 12th group, this factor should be taken into account. The red cooler is slightly more expensive, but it will pay for itself in the third year of operation.

Why paint?

Many motorists do not know, but regardless of the group, all antifreezes are a colorless liquid. However, at the final stage of production, they are painted in a certain color. Why is this being done?

Some people think that antifreezes are given color to distinguish them by groups. But it's not. After all, there are a number of examples when the cooler from the 11th group had a green color, like that of the 12th and vice versa. So why are they painted? This is done so that the driver can identify the leak and warn it in time. Indeed, without antifreeze, the engine can boil in a matter of minutes. By bright color, the driver will accurately determine the location of the breakdown.

Also, the liquid is colored to determine its performance properties. The fact is that over time, the cooler loses its characteristics. Anti-corrosion and anti-foam additives stop working, flakes form. Along with this, the color of the antifreeze itself changes.

Therefore, if the liquid becomes cloudy (or even worse - it has acquired a brown tint), this is the first sign of a replacement. But as practice shows, 90% of antifreezes fully withstand the service life declared by the manufacturer.

Antifreeze G12 red "Dzerzhinsky"

This is a cooler from Dzerzhinsky Plant of Organic Synthesis LLC. It is a carboxylate antifreeze made using organic acid technology.

The composition has a full package of additives and is free from adverse additives (nitrates, phosphates and silicates). Red antifreeze G12 "Dzerzhinsky" is used on cars with both copper and aluminum radiators. The test results showed the following characteristics of the cooler:

• Boiling point is 109 degrees Celsius.
• The crystallization temperature is -41 degrees.
• The mass fraction of distilled liquid at 150 °С does not exceed 49%, which is higher than the requirements of the technical regulation.

Judging by the reviews, this is a very good product. However, not all coolers of this company speak this way. A lot of negativity poured in the direction of the Dzerzhinsky antifreeze. Reviews note that the cooler boils at a temperature of 91 degrees. The squad is not up to the task.

Antifreeze G12 Red Felix

This is also a product of Russian production. Officially delivered to AvtoVAZ. Red antifreeze G12 "Felix" is designed to block foci of corrosion inside the system thanks to a set of high-quality additives. The line includes products for both aluminum andcopper radiators. Felix also has a separate line for trucks with diesel engines. Judging by the responses, the product has good protection against scale and deposits. Unlike Dzerzhinsky, G12 antifreeze (Felix red concentrate) has more positive reviews.

Motorists note the high anti-foam and lubricating characteristics of the cooler. The product freezes at temperatures from -45 degrees Celsius. Antifreeze boils at 110°C. The mass fraction of the distilled liquid is 46% at 150 degrees.

How to mix?

It is worth noting that most imported products are not a diluted liquid, but a concentrate. The G12 red VAG antifreeze (from the Volkswagen-Audi Group) is no exception. The instructions say that it is not necessary to dilute it. But if necessary, it can be replenished so as not to be mixed with other liquids of a different class and color. And you can dilute it with distilled water.

How much to mix?

It depends on the region of operation. For mid-latitudes, the concentrate can be diluted in a 50/50 ratio (but not more, otherwise the freezing point will drop to -20 degrees or less). Never mix antifreeze with other coolant groups, as well as with ordinary tap water. This will degrade the properties of the concentrate up to the occurrence of internal corrosion and foaming. When mixed with distilled liquid, the properties of the coolant remain virtually unchanged.
