Heating and cooling of the cars ' engine work by circulating a special fluid in the system. It is in its properties similar to water. The liquid in constant circulation takes excess heat from the engine and transportorul it to the radiator. Here is that heat is given off into the atmosphere. The liquid – antifreeze. It appeared 50 years ago. Let's look at what the antifreeze, why is it needed, what are the characteristics and how to replace it in the car.

Facts from history

Now you can often hear motorists compare Tosol and antifreeze. But to compare the data of the substance – it's the same as trying to compare fish and carp. The man in the street believes that the antifreeze – it's a coolant with a higher quality. And often the products are imported. And antifreeze – is a domestic product. In other words, the dyed water. People don't know what the antifreeze, but in vain. what is the antifreeze

The Time of its appearance coincides with the release of the first car of "AVTOVAZ". Before that, the radiators were simple water. In the bitter cold in the water, added alcohol, or ethylene glycol. It kept the liquid from freezing.

This composition was crystalline and quite viscous, which excluded the exploding batteries. In older machines had cast iron engines. This liquid was and very safe in terms of corrosion. It was the perfect solution. And called it antifreeze.

The First problem with this line-up appeared when rolled off the first car of "AVTOVAZ". In his cooling system Vazovtsy used very different materials. For them the existing coolant absolutely not suitable. Therefore, public institutions have developed a completely new liquid without corrosive disadvantages – the antifreeze. VAZ model well it worked. The coolant was salt of inorganic origin. They form on metal surfaces the tape to protect the metal from ethylene glycol.

Antifreeze and name

Liquid got its name in the Department name. Product development was involved in CBT, or technology of organic synthesis. Soon the name was transferred to the Antifreeze and then became a brand and a standard for coolants. Properties have been clearly regulated, as the composition. how to change antifreeze

In the Soviet Union produced two classes of these substances. Well, sales were Tosol A-40 and A-65, and antifreeze – M-40 and M-65.

The First liquid was obtained by mixing product brand “A” with plain water. The figure is meant the temperature threshold at which the composition will freeze. The antifreeze was of lower quality.

Antifreeze for «Lada»

Then this name became popular among car enthusiasts and has subsequently become a household name. And as the products of "AVTOVAZ" became increasingly successful and in demand from the people, and antifreeze was the best choice. It was then that the motorists born stereotype – this part will only fit for «Lada».

Antifreeze and its composition

This substance, whose composition is much more difficult water. The last of the liquid, too, but her coolant has other additives. They provide the antifreeze all the properties that it possesses. Let's see what are these properties and why is this product more effective than distilled water.

antifreeze in the engine

The Main ingredient in antifreeze – distilled water. It makes the substance less viscous. Now, knowing what antifreeze can say that the denser coolant, the less it is diluted. Car owners can adjust the density of the composition. This helps to save the liquid.

Another substance, which is contained in antifreeze, – propylene glycol or ethylene glycol. These substances are derived from conventional alcohol. Alcohol and propylene glycol have the same smell and a similar composition. Substance alcohol-based need to in the winter the liquid would not freeze and was able to maintain its initial state. Propylene glycol is colorless, but the smell of it sharp. It can be easily distinguished from all other substances. how to pour antifreeze

Because of a sharp odor manufacturers of coolants added to the special additive, partially compensating an unpleasant odor. The aromatic additive is often your aroma does not and is used to compensate, improving the properties of liquid.

Another important component & ndash; dye. It is necessary to give a fluid of a certain color. Shade makes it easy to distinguish from the other antifreeze coolant – antifreeze.

Unique properties

So we know what is the antifreeze. Is the coolant domestic developments. Let's see what properties it possesses. This liquid is poured into the engines to cool them. But there are other reasons. Cooling can handle any liquid. However, it is antifreeze contains special substances-additives that protect the radiator metal from corrosion. Often the heat exchangers rust from the inside. Anti-corrosion additive creates inside the radiator is a special film. Through it, the moisture can affect the metal and to join with him in reaction. Due to these anti-corrosion properties manages several times to extend the life ofthe engine and the radiator.

For most of other liquids based on water, it is difficult to maintain the desired state at subzero temperatures. But the antifreeze in the engine will not freeze. This liquid contains alcohol. Due to this, the substance will not freeze even at extreme temperatures. Boiling antifreeze only at 110 degrees, which is also fairly important feature.

Domestic product: composition and labelling

Depending on the marking different and the composition of the liquid, its density and specifications. Now in modern classification manufacturers use the letter – A, M, K Numbers – 30, 40, 65. Letters indicates the type of antifreeze – automotive, upgraded concentrate. antifreeze VAZ

The Numbers indicate the freezing temperature. Also, the marking can contain part of the name of the manufacturer. Liquids, freezing temperature is below 65 degrees, the market is now there. The level of crystallization is provided by the concentration of ethylene glycol. As for additives, they are not less than 8. Their number may reach 15.

Selection Rules

Modern manufacturers supply the market with not only the traditional blue liquid – there are lots of other shades. It should be remembered that the color does not affect the technical characteristics. The main purpose of the shade – the differences between manufacturers and the conditions of mixing.

The Temperature at which the coolant boils, is in the range of 104 to 112 degrees. One of the ways to acquire high-quality fluid - check the level density. Good performance from 1,060 to 1,090 grams per cubic centimeter. Replacing antifreeze is made on the same liquid that was poured in the car.

How to replace coolant

To carry out replacement of coolant, no need to go to service center. To perform the operation independently. Can handle even the girls. Need to know a few simple rules, and then no difficulty will arise. Let's look at how to change the antifreeze yourself. It is important to work on a cold engine – when the motor is hot, the surge tank cap to Unscrew it should not be. drain antifreeze

First, put the car on a level surface. This is to ensure that the replacement process was able to completely remove the spent fluid. In other embodiments, complete draining of the system is impossible. Inside sure something will remain. To realize the draining of antifreeze, you need to Unscrew the top and bottom covers of the radiator. It should also be under cover to expose empty containers. Its volume shall be not less than seven litres for passenger cars and not less than ten - for light-duty trucks (such as "GAZelle").

You should Then flush the cooling system and tighten the lower exhaust tube. Next will finally be the long awaited replacement. replacing antifreeze

Liquid poured into the hole of the surge tank to the top, and then sealed. After that, the car make and monitor the readings of temperature sensor. Next, check the level and if necessary fill again the fluids. Here's how to fill antifreeze – this guide is relevant for all vehicles.
