What antifreeze is to fill in BMW x5 E70. Increased antifreeze flow on BMW: What is the reason? What antifreeze to choose for bmw x5

Is the dominant component we use when maintenance car. Because when it is not possible stable work its engine. In Soviet times, car enthusiasts used toosol, which was intended for domestic auto industry. Nowadays, there are a huge number of foreign cars through the streets and for each model there is a certain antifreeze.

With long-term use for BMW, gradually loses its qualities: protection of the engine system from overheating and cooling systems from corrosion becomes minimal. Therefore, experts recommend to produce it after 60-80 thousand mileage kilometers. However, a small number of motorists adhere to this rule, which leads to a decrease in engine performance.

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

caid key, hydraulic lift, small amount of water, vessel for waste coolant, as well as sealing ring for drain pluglocated on the cylinder block.

In case you are replaced by a hundred, pay attention to the fact that some experts fill the barrel new liquid By 50%, it is incorrect and can harm your car. Therefore, try to fill out the bar almost read.

When replacing antifreeze for BMW, the following requirements should be performed:

1. it is impossible to mix cooling fluids for different models, as this will subsequently lead to disastrous consequences;
2. it is forbidden to open the barrel stop, if the engine is in a hot condition, you need to wait until it cools, and only then fill the liquid;
3. replacement should occur in the exact sequence, which is indicated in the instructions for the coolant;
4. antifreeze is a very dangerous substance for human health, so it is necessary to exclude its possibility of human skin. Otherwise, rush to rinse with water affected areas and tied with a sterile bandage.

So, if you replaced the antifreeze, the only unresolved question remains: what to do with a waste liquid? In no case do not pour it on the ground or in the sewer, and contact a special service involved in the disposal of harmful substances.

The cooling system is longly filled with a mixture of water and antifreeze with an anti-corrosion additive from the VW / SEAT concern. This mixture prevents the freezing and corrosion of the cooling system, salt deposition and, in addition, increases the boiling point of the coolant. In the circuit of circulation, as a result of the expansion of the fluid during heating, an increased pressure is created, which also helps to increase the boiling point of the coolant. The pressure is limited to the valve opened at a pressure of 1.4 - 1.6 bar located in the lid of the expansion tank. For impeccable operation of the engine cooling system required heat Boiling fluid boiling. With too low boiling point, steam plugs can form, which is why the engine cooling deteriorates. Therefore, the cooling system year must be filled with a mixture of water and antifreeze.

It is necessary to use antifreeze G12 Plus (purple, accurate designation G 012 A8F) or another concentrate with a mark "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 antifreeze G12 (red, exact designation G 012 A8D), then to replenish the level of the coolant, you can also use antifreeze G12 or another concentrate with a mark "in accordance with VW / AUDI-TL-VW- 774-D », for example, Glysantin-Alu-Protect / G30. Note: G12 of purple color can be mixed with G12 red.

ATTENTION: It is impossible to mix antifreeze G12 red and older antifreeze G11 green, since this can lead to very strong damage to the engine. Cooling brown liquid (the result of antifreeze antifreeze and G11] to be replaced without delay.

Note: If the cooling system accidentally turned out to be liquid with the addition of antifreeze of the incorrect specification, the system must be rinsed. To do this, the whole liquid from the cooling system should be completely drained and fill the system with clean water. Leave the engine to work for two minutes on idling. Water to drain again and blow the system from the side of the expansion tank with compressed air to fully release it. Wrap the plug hole and fill the cooling system with a mixture of water and antifreeze G12-PLUS.

ATTENTION: To replenish the cooling system (also in the warm season], it is necessary to use only a mixture of the G12-Plus tool (purple) with soft water. The proportion of antifreeze is also in the summer period should not be below 40%. Therefore, when replenishing the cooling system Water should always add antifreeze.

In our latitudes, the coolant should provide protection against freezing to -25 ° C, and even better - to -35 ° C. The proportion of antifreeze should not exceed 60% (protection against freezing the coolant to -40 ° C), otherwise the protection against freezing and the cooling effect of the liquid is reduced. Note:depending on the equipment of the car, the amount of filling coolant can be somewhat different from the values \u200b\u200bindicated in the table

The ratio of coolant components in liters

IN last years The problem of coolant leakage from the system is faced by the owners not only cars with big mileage, but also relatively new cars. Increased flow Antifreeze is noted on BMW removed from the production of models: E46 (3rd series), E31 Gran Turismo (8th series), E38 and E39 (5th series). And if the supported machines have been explained by a large wear, then the fluid leak at the modern version of F10 clearly indicates that someone in BMW gets its money in vain.

Why is the cooling system break on the BMW?

On increased consumption of antifreeze on car BMW warns the sensor on dashboardwhich can be disconnected after the engine warming up or tilt. Other signs of leakage working fluid From the cooling system is:

• After the car on the road or in the garage there are wet spots.
• Of exhaust pipe Going white smoke.
• When starting or stopping the engine, "bull-" sounds are heard.
• In the cabin auto the smell of antifreeze.
• In the crankcase increased the level of engine oil.

With a careful inspection, fresh drips can be found on the engine block, which is desirable to periodically clean. Traces of coolant are also detected in the connecting places of nozzles and hoses.

Causes of coolant leaks

Coolant consumption on cars BMW due to depressurization of the system. The most common causes of antifreeze leaks for the models mentioned in the article are as follows:

E46 - Defective plug and cracks of the expansion tank.

E31 with M60 engine - fast wear of the pool shaft seal.

E38 and E39 with M62 motors - incorrect operation of a programmable thermostat.

F10 - depressurization of the radiator at the junction of an aluminum heat exchanger and plastic tanks.

Also, antifreeze is sometimes leaking through the cylinder head gasket breaks through the block. Depending on the place of destruction, the coolant can fall on the outer surface of the engine, into the oil canal and to the combustion chamber. That in any case is not good.

Diagnostics and troubleshooting

Finding the leakage of antifreeze - the occupation is not easy. The diagnostics of the cooling system is carried out in different ways - the methods used are largely dependent on the level of equipment of the car service (or garage). Start recommended in checking places of connections of nozzles, hoses, sealing gaskets with a wiping of their clean cloth. It remains tracks from antifreeze - it is not necessary to scare this.

You can also diagnose the breakdown by adding a painting pigment visible to UV rays, with a subsequent pressing system. The leakage of the working fluid is detected when lighting motor compartment Special lamp.

The latest method is the most effective - when it is used, it does not have to spend a bunch of time to track the status of the car.

• Repair of the cooling system in the overwhelming majority involves the replacement of defective parts and nodes:
• Expansion tank and corks when detecting cracks.
• Cooling fluid pump and sealing gasket.
• Programmable thermostat (with refreshing ECU or without it).
• Gaskets of the cylinder head with preliminary dismantling.
• The main radiator, heat exchanger and salon stove valve.

In the process of eliminating faults, it is recommended to install new hoses and nozzles and fill fresh antifreeze into the system.

IN bMW cars You need to use only those coolants that manufacturer recommends. Ignoring the manufacturer's requirements may result in serious breakdowns and failure to warranty repair cars.

BMW has its own classification of cooling fluids. But since most manufacturers of antifreezes agreed to use the generally accepted separation depending on the composition, characteristics, the conditions of application (G11 - Blue, G12, G13, G12 ++ shades of red, G13 - yellow and orange), then any original antifreeze from the BMW line has its own in this classification Analogue

Your color from the original antifreeze BMW. - Blue shade, but most modern BMW engines (Series E, F, G) are suitable for antifreeze of the generally accepted classification G12 + and G12 ++ (shades of red). But there are exceptions: for example, in the "seven" in the body F01 recommend pouring G13 (yellow and orange). The same class of coolant is recommended for some late M-Power models (for example, M4 or M6). In this material, we will tell about how on external signs to know that antifreeze is time to change, what will happen if this is not done, in what conditions the cooling fluid is flawed faster and why, if you are not sure about the choice of fluid, it is better to contact professionals.

BMW Antifreeze Replacement Cost

Coolant service life (antifreeze)

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

Signs of wear antifreeze

With age, antifreeze loses its natural properties, the number of additives gradually decreases in it. Because of this, the cooling fluid worsens heat, the corrosion of engine parts increases. The signs of aging can be judged if:

• Due to the reduction of heat transfer, the engine begins to overheat (indication on the instrument panel);
• Antifreeze lost its original color (responded);
• Antifreeze became red-brown (signs of strong corrosion of engine parts);
• Antifreeze is stratified and flakes appear in it;
• Coolant begins to foam;
• The boiling point of the liquid is reduced;
• The radiator fan works more often.

If the cooling fluid (antifreeze) does not replace on time

If the situation is emergency and the engine requires repair, the coolant should be replaced after all the work (there is difficult to miss the replacement). And if we ignore the replacement of "just" worn antifreeze, then this threatens us:

• Permanent overheating of the engine (strong overheating can lead to the cracking of the cylinder block, deformation of the head of the cylinder block and so on.);
• Increased corrosion of engine parts (reduction of its resource);
• Increasing the wear of the cooling system (the radiator fan works more often).

What is needed cooling fluid (antifreeze)

Recently almost all bMW engines Growth occurred operating temperature and thermal loads. In such conditions, the life expectancy of the engine is very dependent on uninterrupted cooling. It provides a system forced fluid circulation. The liquid in this system is antifreeze.
