The density of the antifreeze and its composition

Tosol is the most famous domestic antifreeze for car cooling systems. When choosing this substance, it is necessary to evaluate a number of its parameters. First of all, this is the quality of the product that is on sale. From this will depend on the correct operation of the car's systems, their durability.

The density of antifreeze is one of the most important characteristics that allows you to evaluate the customer's performance. After all, the compliance of antifreeze with modern requirements is a guarantee of the correct operation of all mechanisms.

General characteristics and composition

To understand how to measure the density of antifreeze and antifreeze, you need to understand their characteristics and definition. The substance presented is necessary for cooling the motor in the summer and protecting it from mechanical damage in the winter.

The name of the antifreeze is based on the abbreviation. TOC - technology of organic synthesis. The last two letters of the name denote the belonging of the substance to the group of alcohols, which, as you know, end with "ol".

The basis of antifreeze is glycol ether. The composition includes about 10 different additives. Thanks to this antifreeze is not amenable to frost or heat, does not boil and does not foam. Special additives eliminate the impact on the materials of the mechanisms, so that they become not subject to corrosion. Tosol can be stored and operated for a long time due to its special composition.

What characterizes the density?

может многое рассказать о состоянии этого вещества при эксплуатации. The density of antifreeze can tell a lot about the state of this substance during operation. Therefore, it is required to carry out regular checks. This indicator is influenced by several main factors. First of all, this is the composition and formulation of the production of antifreeze. Each manufacturer applies a certain technology in the manufacture of its refrigerant.

The second important factor is the number and set of additives. These components improve the performance of the antifreeze and additionally protect the systems and mechanisms from premature wear. In the manufacturing process, technologists use a certain set of these additional components. They are clearly balanced. Some of them are incompatible and depend on the operating conditions of the equipment.

The last important factor that affects the density of antifreeze is the amount of monoethylene glycol in it. All these features affect the heat capacity and thermal conductivity. If the density of the antifreeze changes, this can lead to unfortunate consequences.

How to measure density yourself?

Considering how to check the toxol density, you should pay attention to the simplest methods. Special equipment helps to measure for any liquid. This device is called a hydrometer. It is easy to use. In this case, only a few simple actions are performed.

Initially, open the bonnet cover. Next, you need to find an expansion tank, in which the antifreeze is located. Its lid is opened. A hydrometer takes the required amount of antifreeze. For this, the pipette is lowered into the coolant and the substance is taken into the flask. The float must be able to balance freely.

On the scale of the hydrometer it is necessary to measure the antifreeze concentration index. Further, the result is compared with the nominal value indicated by the manufacturer. In some cases, the density may be lower or higher than claimed. This can also be affected by the amount of water in the solution.

Result of measurement

Now you know how to check the toxol density with a hydrometer, now you need to understand the result. The density index is affected by water, which is diluted antifreeze in the factory or home conditions. With the increase in its content in the solution, the freezing temperature of the substance becomes higher, and the cooling characteristics deteriorate in the summer.

If the density of the substance in the measurement is underestimated, it means that the composition of the antifreeze includes a large amount of water. The range of operating temperatures in this case is reduced in tosola. This is a negative trend.

Increased concentration indicates a decrease in the properties of cooling and lubrication mechanisms. Because of this, they wear out quickly. Therefore, it is necessary to compare the nominal density declared on the package with the hydrometer readings. If necessary, it is corrected.

Normative value

One of the most popular types of the substance is the antifreeze of grade A-40 or A-40M. This refrigerant is used in a relatively warm climate, where the temperature does not drop below -38 ° C in winter. Among motorists of our country, it is widely believed that the density of the antifreeze A-40 is 1.075 g / cm³. At the same time, about 44% of water and 56% of ethylene glycol (or higher) are present in the mixture.

The density index depends on the temperature at which the measurement was made. Standards set the permissible rate of this value at the level of 1,065-1,085 g / cm³. The ambient temperature should be at + 20 ° C.

If the number obtained during the measurements does not correspond to this indicator, it can be aligned. To do this, a little old antifreeze is blended and a water or concentrate of antifreeze is added to the total mixture.

Lifetime

Knowing what the density of the antifreeze is currently affecting the car's systems, as well as what the normative value of this indicator is, you can avoid premature repairs or breakdowns of the car. Over time, the antifreeze ages. Its service life depends on the quality of the antifreeze and the mileage of the car.

If the density of the mixture is low, a large amount of water is present in the solution. It degrades the effect of additives and provokes the formation of corrosion. This leads to a rapid destruction of the surfaces of the mechanisms. In this case, the liquid becomes rusty. Regardless of the life of such a substance, it should immediately be replaced with a new antifreeze.

How to change the antifreeze

If you measured the density of the antifreeze, assessed its visual characteristics and found it necessary to replace this substance, it is necessary to carry out a special procedure. The engine is warmed up for 5 minutes. The heater cock in the passenger compartment must be open. After stopping the engine, the old antifreeze is drained, and pure water is poured in instead. You can then use a special agent for washing. It is used in accordance with the manufacturer's instructions.

Through the drain plug, which is located in the radiator, the water is removed from the system. Rinsing is done until the liquid is clean. After that you can pour in a new antifreeze.
