Who produces antifreeze for BMW. What antifreeze to fill in BMW X5 E70. Here is the algorithm for working

It is the main component that we use when maintenance car. After all, in its absence, stable operation of its engine is not possible. In Soviet times, car enthusiasts used antifreeze, which was intended for the domestic automobile industry. These days, there are a huge number of foreign cars driving on the streets, and for each model there is a specific antifreeze.

With prolonged use for BMWs, it gradually loses its qualities: protection of the engine system from overheating and the cooling system from corrosion becomes minimal. Therefore, experts recommend replacing it after 60-80 thousand kilometers. However, a small number of car enthusiasts adhere to this rule, which leads to a decrease in engine performance.

In order to make antifreeze yourself, you will need the following items:

a spanner wrench, a hydraulic lift, a small amount of water, a container for waste coolant, and an O-ring for the drain plug located on the cylinder block.

If you make a replacement at a service station, please note that some specialists fill the barrel 50% with new fluid; this is incorrect and can harm your car. Therefore, try to fill the barrel almost completely.

When replacing antifreeze for BMW, the following requirements must be met:

1. do not mix coolants intended for different models, since this will subsequently lead to catastrophic consequences;
2. it is forbidden to open the barrel cap if the engine is hot, you need to wait until it cools down and only then fill in the liquid;
3. replacement must occur in the exact sequence indicated in the instructions for the coolant;
4. Antifreeze is a very dangerous substance for human health, so it is necessary to prevent its contact with human skin. Otherwise, rinse the affected areas with plenty of water and bandage with a sterile bandage.

So, if you have replaced the antifreeze, the only unresolved question remains: what to do with the used fluid? Under no circumstances should you pour it onto the ground or into the sewer, but contact a special service that deals with the disposal of harmful substances.

BMW has its own classification of coolants. But since most antifreeze manufacturers have agreed to use a generally accepted division depending on the composition, characteristics, and conditions of use (G11 - blue, G12, G12+, G12++ shades of red, G13 - yellow and orange), then any original antifreeze from the BMW line has its own in this classification analogue

The original has its own color BMW antifreeze- bluish tint, but most modern BMW engines (E, F, G series) are suitable for antifreeze of the generally accepted classification G12+ and G12++ (shades of red). But there are exceptions: for example, it is recommended to pour G13 (yellow and orange) into the “seven” in the F01 body. The same class of coolant is recommended for some later M-Power models (for example, M4 or M6). In this material we will talk about how to tell by external signs that it is time to change the antifreeze, what will happen if this is not done, under what conditions the coolant wears out faster and why, if you are not sure about the choice of fluid, it is better to turn to professionals.

Coolant (antifreeze) service life

Change the coolant to BMW cars should be every 4 years (for M-series cars this period is reduced to 3 years). On some models, according to the manufacturer, antifreeze is (formally) filled for the entire service life of the car. But when repair work, according to technology, it changes to a new one. Also, before each winter season, the concentration of antifreeze should be checked.

Signs of antifreeze wear

With age, antifreeze loses its natural properties, and the amount of additives in it gradually decreases. Because of this, the coolant dissipates heat less well and corrosion of engine parts increases. Signs of aging can be judged if:

• Due to a decrease in heat transfer, the engine begins to overheat (indication on the instrument panel);
• Antifreeze has lost its original color (faded);
• The antifreeze has turned reddish-brown (signs of severe corrosion of engine parts);
• The antifreeze separates and flakes appear in it;
• The coolant begins to foam;
• The boiling point of the liquid decreases;
• The radiator fan operates more often.

If the coolant (antifreeze) is not replaced on time

If the situation is emergency and the engine requires repair, then the coolant should be replaced after all the work (it’s difficult to skip the replacement). And if we ignore replacing “just” worn-out antifreeze, then this threatens us:

• Constant overheating of the engine (severe overheating can lead to burnout of the cylinder block gasket, deformation of the cylinder head, etc.);
• Increased corrosion of engine parts (reduction of its service life);
• Increased wear and tear of the cooling system (the radiator fan operates more often).

What is coolant (antifreeze) used for?

Lately, almost everyone BMW engines there was an increase operating temperature and thermal loads. In such conditions, the life expectancy of the engine is very dependent on uninterrupted cooling. It is provided by a forced fluid circulation system. The liquid in this system is antifreeze.

The cooling system is filled year-round with a mixture of water and antifreeze with an anti-corrosion additive from the VW/SEAT concern. This mixture prevents freezing and corrosion of the cooling system, salt deposits and, in addition, increases the boiling point of the coolant. In the circulation circuit, as a result of expansion of the liquid when heated, increased pressure is created, which also contributes to an increase in the boiling point of the coolant. The pressure is limited by the expansion tank valve opening at a pressure of 1.4 - 1.6 bar. For the perfect functioning of the engine cooling system, it is required high temperature boiling coolant. If the boiling point is too low, vapor locks can form, causing poor engine cooling. Therefore, the cooling system must be filled with a mixture of water and antifreeze all year round.

It is necessary to use antifreeze G12 Plus (purple color, exact designation G 012 A8F) or another concentrate marked “in accordance with VW/SEAT-TL-VW-774-F”, for example, Glysantin-Alu-Protect-Premium/G30.

If the cooling system is filled with a mixture containing G12 antifreeze (red, exact designation G 012 A8D), then red G12 antifreeze or another concentrate marked “according to VW/AUDI-TL-VW-” can also be used to replenish the coolant level. 774-D", for example Glysantin-Alu-Protect/G30. Note: G12 purple can be mixed with G12 red.

Caution: Do not mix red G12 antifreeze with the older green G11 antifreeze, as this can cause severe engine damage. The coolant is brown (the result of mixing antifreeze G12 and G11), replace it immediately.

Note: If a liquid with an antifreeze additive of the wrong specification accidentally ends up in the cooling system, the system must be flushed. To do this, all liquid from the cooling system should be completely drained and the system filled with clean water. Leave the engine running for two minutes idling. Drain the water again and blow out the system from the side of the expansion tank with compressed air to completely empty it. Close the drain plug and fill the cooling system with a mixture of water and G12-Plus antifreeze.

Attention: To replenish the cooling system (also in the warm season), only use a mixture of G12-Plus (purple) with soft, clean water. The proportion of antifreeze, also in summer, should not be lower than 40%. Therefore, when refilling the cooling system Antifreeze should always be added to water.

In our latitudes, the coolant should provide protection against freezing down to -25 °C, or even better - down to -35 °C. The proportion of antifreeze should not exceed 60% (antifreeze protection of the coolant down to -40 °C), otherwise the antifreeze protection and cooling effect of the liquid are reduced. Note: Depending on the vehicle’s equipment, the amount of coolant filled may differ slightly from the values ​​​​indicated in the table
