In recent years, owners of not only high-mileage cars, but also relatively new cars, have faced the problem of coolant leakage from the system. Increased consumption antifreeze marked on BMW discontinued models: E46 (3rd series), E31 Gran Turismo(8th series), E38 and E39 (5th series). And if used cars this problem due to high wear, then a fluid leak in the modern version of the F10 clearly indicates that someone at BMW is getting their money in vain.
Why does the BMW cooling system fail?
About the increased consumption of antifreeze for auto bmw alerts the sensor dashboard, which can be turned off after the engine has warmed up or topped up. Other signs of a leak working fluid from the cooling system is:
- After a car, wet spots remain on the road or in the garage.
- From exhaust pipe white smoke comes out.
- When starting or stopping the engine, "gurgling" sounds are heard.
- The interior of the car smells of antifreeze.
- The engine oil level has risen in the crankcase.
Upon close inspection, fresh streaks can be found on the engine block, which is desirable to clean periodically. Traces of coolant are also found at the junctions of pipes and hoses.
Causes of coolant leaks
Coolant consumption on BMW cars is due to system depressurization. The most common causes of antifreeze leaks for the models mentioned in the article are as follows:
E46 - defective plug and expansion tank cracks.
E31 with M60 engine - rapid wear pump shaft seal.
E38 and E39 with M62 engines - incorrect work programmable thermostat.
F10 - depressurization of the radiator at the junction of the aluminum heat exchanger and plastic tanks.
Also, antifreeze sometimes leaks through a broken cylinder head gasket. Depending on the location of the destruction, the coolant can enter the outer surface of the engine, into the oil channel and into the combustion chamber. Which is not good anyway.
Diagnostics and Troubleshooting
Finding an antifreeze leak is not an easy task. Diagnostics of the cooling system is carried out in different ways - the methods used largely depend on the level of equipment of the car service (or garage). It is recommended to start by checking the joints of pipes, hoses, gaskets and wiping them with a clean cloth. There are traces of antifreeze on it - this should not be scared.
It is also possible to diagnose a breakdown by adding a coloring pigment visible in UV rays to the coolant, followed by pressing the system. Leakage of working fluid is detected when illuminated engine compartment special lamp.
The last method is the most effective - when using it, you do not have to spend a lot of time tracking the condition of the car.
- Repair of the cooling system in the vast majority of cases involves the replacement of defective parts and assemblies:
- Expansion tank and plugs when cracks are detected.
- Coolant pump and gasket.
- Programmable thermostat (with or without ECU flashing).
- Cylinder head gaskets with its preliminary dismantling.
- The main radiator, heat exchanger and saloon stove valve.
In the process of troubleshooting, it is recommended to install new hoses and pipes and fill the system with fresh antifreeze.
BMW vehicles should only use coolants recommended by the manufacturer. Ignoring the manufacturer's requirements can lead to serious damage and failure to warranty repair cars.
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, the deposition of salts and, in addition, increases the boiling point of the coolant. In the circulation circuit, as a result of the expansion of the liquid during heating, an increased pressure is created, which also contributes to an increase in the boiling point of the coolant. The pressure is limited by a valve located in the cover of the expansion tank, which opens at a pressure of 1.4 - 1.6 bar. The engine cooling system requires a high boiling point for the coolant to function properly. If the evaporating temperature is too low, vapor locks can form, which impairs engine cooling. Therefore, the cooling system must be filled with a mixture of water and antifreeze all year round.
You must use G12 Plus antifreeze (purple, exact designation G 012 A8F) or another concentrate marked “according to 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), you can also use red G12 antifreeze or another concentrate marked "according to VW/ AUDI-TL-VW-" to replenish the coolant level. 774-D", e.g. Glysantin-Alu-Protect/G30. Note: G12 purple can be mixed with G12 red.
Attention: Do not mix red G12 antifreeze or more old antifreeze G11 is green because it can cause very severe engine damage. coolant Brown(the result of mixing G12 and G11 antifreezes) replace immediately.
Note: If a liquid with an incorrect specification of antifreeze is accidentally found in the cooling system, the system must be flushed. To do this, all liquid from the cooling system must be completely drained and the system filled with clean water. Let the engine run for two minutes Idling. Drain the water again and blow through the system from the side of the expansion tank compressed air to free it completely. Wrap the cork drain hole 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 (lilac) with soft clean water. The proportion of antifreeze should not be lower than 40% even in summer. Therefore, when replenishing the cooling system antifreeze should always be added with water.
In our latitudes, the coolant should provide protection against freezing down to -25 ° C, and even better - up to -35 ° C. The proportion of antifreeze must not exceed 60% (antifreeze protection of the coolant down to -40°C), otherwise the antifreeze protection and cooling effect of the liquid will be reduced. Note: Depending on the equipment of the vehicle, the amount of coolant to be filled in may differ slightly from the values indicated in the table.
The ratio of the components of the coolant in liters
It is the main component that we use in maintenance car. Indeed, in its absence, stable operation of its engine is not possible. V Soviet time motorists used antifreeze, which was intended for domestic auto industry. Nowadays, a huge number of foreign cars drive through the streets, and for each model there is a certain antifreeze.
With prolonged use for BMW, it gradually loses its qualities: the protection of the engine system from overheating and the cooling system from corrosion become minimal. Therefore, experts recommend replacing it after 60-80 thousand 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:
ring wrench, hydraulic lift, a small amount of water, a container for used 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 experts fill the barrel with new fluid by 50%, this is wrong and can harm your car. Therefore, try to fill the barrel almost full.
When replacing antifreeze for BMW, the following requirements must be met:
- Do not mix coolants intended for different models, as this will subsequently lead to disastrous consequences;
- it is forbidden to open the barrel plug, if the engine is hot, you need to wait until it cools down, and only then fill in the liquid;
- replacement must occur in the exact sequence that is indicated in the instructions for the coolant;
- antifreeze is a very dangerous substance for human health, so it is necessary to exclude its possibility of 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? In no case do not pour it onto the soil or into the sewer, but contact a special service that deals with the disposal of harmful substances.

Actually, why it was necessary to change the thermostats: When driving at speed, the temperature of the internal combustion engine did not rise more than 72 degrees (test No. 7) Both the USR thermostat and the Main thermostat were replaced. After that, the temperature became correct, namely 88-92 degrees when driving at speed. At the beginning the upper thermostat was replaced, but this did not give the desired result! Of the pluses, the engine began to run softer and became even more economical! And now, in fact, how it all changed:
We remove the decorative plate. Remove the spacer, disconnect the hood cable. We remove the electric fan, when removing it from the corner of the fan on the driver's side, you need to fold its retainer, which is inserted into the ear, otherwise it will rest against the pipe. At first, you might think that it is not folding.))) in the lower left corner on the driver's side. You can see in the photo. There is no plug on the radiator! All antifreeze was drained, including from the engine block and replaced with a new one. To get to the drain plug from the block, you need to remove the air pipe that goes from the turbine to the air filter. The pipe is screwed to the filter with Torx bolts diagonally, it is simply inserted into the turbine. The block drain plug is located next to the turbine. The radiators were thoroughly washed from Karcher using a cleaner, the kondeya radiator was washed in place without removal. When washing, you need to be more careful honeycombs are very small, they can be easily damaged, and they are also severely corroded by reagents, honeycombs become brittle! At the same time, the EGR valve was cleaned, the plans are to remove it altogether along with the swirl flaps and the EGR radiator, put plugs everywhere and flash the system to work without the EGR so as not to clog the intake tract with soot and work in clean air! But this later mileage is not yet big.
BMW X5 antifreeze replacement
Cooling the liquid through the use of various concentrates or antifreezes is easy. Before pouring into the neck located under the hood, we first dilute the concentrate with distilled water, observing the proportions indicated on the box.
Antifreeze is needed to prevent corrosion of the cooling system and to protect the engine from overheating. Over time, usage in the system changes basic characteristics, heat dissipation performance deteriorates. For proper cooling, the antifreeze is drained and replaced with a new one. We do this procedure closer to winter. But there are still skeptical motorists who consider it inappropriate to drain something and pour something into the coolant reservoir. This is fundamentally wrong, and a BMW X5 antifreeze replacement is needed.
Step 1 Cool the engine to the minimum temperature. Antifreeze is a greasy liquid that, when heated, leaves serious burns on the body.
Step 2 We unscrew the iron shield of the motor and the plastic protection located under the bumper. The required capacity for draining is about 12 liters.
Step 3 Unscrew the indicated blue radiator cap with a key of 13.
Step 4 Drain everything that is in the radiator. You will get about 7 liters.
Step 5 Then unscrew the plug with right side on the engine block, which is hidden under the exhaust manifold. The key is the same - at 13.
Step 6 The next plug is on the left side of the engine block. We unscrew it. Problems arise due to the location of the dispenser and drive. Therefore, we take the head at 13. There are about 1.5 liters. Drain carefully. Do not be surprised that there is less antifreeze here. If you unscrew it from the left side first, less antifreeze will be on the right side. Due to the fact that it is freer on the right side, it is more convenient to substitute a container for draining.
Step 7 We twist all the plugs in the reverse order. Plastic with little effort - about 3 Nm.
Step 8 Pour antifreeze into the coolant reservoir. Next to it is a valve for a Phillips screwdriver. At the time of filling the antifreeze, we unscrew it - air is released from the system from there. After releasing it, twist it back. It is necessary to fill in the liquid to the mark indicated on the float.
Step 9 We start the car and turn on the stove to the end, and the blower fan - to the first or second position.
Step 10 We warm up to the desired for optimal performance engine temperature and carefully monitor all pipes and outlets for leakage. If all is well, we turn off the car and re-check the system for smudges. Then we install the protective fasteners in place.
Step 11 After the last protection has been screwed on, we check the level of antifreeze in the barrel. If it has decreased, you need to add to the required mark.
Step 12 In the morning before starting the engine, open the tank and look at the level. If antifreeze is low again, top up.
The replacement process is complete. Feel free to hit the road!

Replacing antifreeze in BMW X5 (E53, E70, F15)
Antifreeze is a special non-freezing process fluid that is designed to cool the car engine during its operation at any time of the year. Its other functions are:
- water pump bearing lubrication;
- prevention of corrosion on metal parts power unit.
The performance of the internal combustion engine and the duration of its operation without repair directly depend on how timely the BMW X5 antifreeze (E70, E53, F15) is replaced and the quality of the composition being poured.
Come to the "M-Center"
You can do this work yourself, but for this you need to know exactly what, when and how to fill it in order to get the desired result, and not harm your car. Therefore, it is much easier and more reliable to visit our car service and trust the professionals.
With us you will get the most favorable prices to replace BMW X5 antifreeze in Moscow. The cost depends on the modification of the car and is:
- 1320 rubles for E53;
- from 1540 rubles for E70;
- from 2200 rubles for F15.
It takes us from 1 to 2 hours for the whole work, including quality control, depending on the modification of the machine. It is not safe to work with hot antifreeze, so you must first wait for the system to cool to an acceptable temperature, and after replacing it, you must definitely warm up the internal combustion engine and bleed the system with diagnostic equipment(for modifications with an electric pump).
Why do you need to do this
Periodic replacement of BMW X5 antifreeze is necessary for a number of reasons, in particular if:
- its expiration date ends set by the manufacturer, due to which the concentration of inhibitors in the composition decreases, which leads to a deterioration in heat transfer and a corresponding decrease in the quality of engine cooling;
- the engine or its cooling system was repaired.
Poor-quality antifreeze (filled with such initially or already spent its resource) can lead to quite serious problems, including:
- internal corrosion in the cooling system;
- increased pump wear due to deterioration of lubricating properties;
- negative oxidative effect on the metal parts of the power unit;
- frequent overheating of the engine, which can lead to its complete breakdown.
Periodicity
The first replacement of antifreeze in the BMW X5 E70 (E53, F15) must be carried out no later than three years from the date of purchase of the car or its last filling. However, the interval should be significantly shorter if the quality of the antifreeze has deteriorated significantly, as determined by:
- measurements with a hydrometer or refractometer;
- change in the color of the liquid, the appearance of turbidity in it;
- the appearance of scale, foam, etc.
That is why, at each MOT, car service specialists check the system without fail internal combustion engine cooling, so as not to miss the moment when its contents will need to be completely replaced.
What to fill
The most important condition correct replacement antifreeze in the BMW X5 F15 (E53, E70) is the correct selection of the composition for filling (it differs depending on the modification and year of manufacture of the car). In general, there are several basic types of coolants:
- traditional is the well-known ancient antifreeze, which for modern cars categorically not suitable;
- hybrid - type G-11;
- carboxylate - types G-12 and G-12+;
- lobrid - types G-12++ and G-13.
We use original antifreeze BMW and Pentofrost nf, which is diluted with distilled water to the required concentration, corresponding to a freezing temperature of -40 degrees Celsius.

Replacing antifreeze on a BMW X5 E70
The procedure for replacing antifreeze with a BMW X5 E70 N52 does not differ from similar processes not only for this brand of car, but also for cars in general. The car owner requires certain technical knowledge and experience, if they are available, all operations can be performed independently, without recourse to specialists.
Causes of coolant leakage from the tank
An urgent issue for many car owners is the leakage of antifreeze from the BMW X5 E70. If, during a routine inspection, a decrease in the coolant level is detected in the expansion tank, the system should be checked for malfunctions.
There are two main reasons why the level of antifreeze decreases - leakage due to worn or loose connections and the development of the coolant itself. In the first situation, after checking the system, replacement parts are purchased and the necessary repairs are made.
If all connections are in good condition, pay attention to the service life and quality of the antifreeze itself. At long-term operation it does not provide the proper level of cooling and at the same time heats up itself.
The pressure regulation system provides for the release of accumulated gases. Given this factor, antifreeze simply boils away. If it has changed recently, this indicates a low quality product. This coolant needs to be replaced immediately.
When checking the condition of the antifreeze in the expansion tank, pay attention to the purity of the solution. If foam, sediment, debris or other impurities are found, this also indicates the need to replace and check the system.
To change certain parts or coolant, the car owner does not need to contact specialists, all manipulations can be done independently. This will require knowledge of the technical location of the components of the cooling system and its components, as well as following a simple procedure.
Step-by-step instructions for replacing antifreeze
If a coolant leak is detected, the replacement of antifreeze begins with an inspection of the entire system. If faulty parts or fasteners are found, new ones are bought to replace them. The coolant in this situation will also have to be changed.
To replace antifreeze in a BMW X5 E70, you will need the following equipment:
- a set of screwdrivers and wrenches, pliers and pliers, other tools depending on the parts to be replaced;
- clean rag, rags, rubber gloves, filling funnel;
- a container for draining the waste liquid and washing with a volume of 12 liters or more;
- consumables - new parts, antifreeze, flushing agent, distilled water.
In the process of preparation and when replacing antifreeze in the BMW X5 E70, attention is also paid to safety precautions:
- all work with connections is carried out with a cooled engine to avoid burns;
- when opening covers and drains, take into account the pressure that can lead to splashes and coolant ingress on the face and hands;
- antifreeze has a high level of toxicity, all liquid, including washing mixtures and water drained after washing, is collected in containers, they are not allowed to enter the soil;
- due to toxicity, the interaction of animals and children with coolant and appropriate mixtures is also not allowed; it is recommended for the car owner himself to carry out all work with gloves.
The procedure for replacing antifreeze is conditionally divided into three stages: draining, flushing and filling. Flushing is not considered mandatory, however, if the drained coolant turned out to be of poor quality or it is planned to switch to new brand- the system is thoroughly cleaned.
Taking into account the specifics of the assembly BMW cars X5 E70 antifreeze replacement procedure has the following procedure:
- the car is parked on level ground, if available, a repair pit is used;
- as an additional precaution, some car owners recommend disconnecting the minus on the battery;
- unscrew the protective shield of the motor and plastic protection under the bumper
- after substituting the container for draining the used antifreeze with a key of 13, unscrew drain plug radiator;
- with the same key, unscrew the drain on the right side of the cylinder block, drain the used fluid from it;
- the rest is drained from the left side of the block by unscrewing a similar plug;
- while the used coolant is being drained, worn parts and connections are being replaced;
- about 12 liters of antifreeze should drain, if significantly less, it is recommended to undergo a diagnosis from specialists;
- all plugs are twisted, a flushing agent or distilled water is poured into the system;
- the engine warms up with the stove turned on, after which it is allowed to cool, the flush is drained according to the above scheme;
- the system is flushed with distilled water until it remains relatively clean at the outlet;
- after washing is completed, all connections are returned to their original form, check the tightness of the fasteners;
- if a concentrate was bought, and not ready-made antifreeze, it is diluted with distilled water with its percentage in 30-50%, mixing is done in a separate container;
- a valve is located next to the filler neck - when pouring new antifreeze, it is unscrewed to bleed air from the system;
- the coolant is poured to the maximum mark on the expansion tank, after which all the plugs are screwed in, the engine warms up to operating temperature again;
- the antifreeze level is checked, if necessary, it is added again to the maximum value.
Within a few days after replacement, the condition of the new coolant should be checked. Pay attention to the liquid level, if it has dropped, add it again and at the same time check the system for new leaks and loose connections.
If the color has changed significantly or the antifreeze has become discolored, it must be replaced. Significant color changes indicate poor-quality production. These consumables should only be purchased from official dealers, such may darken slightly over time, but do not change in color.
How to remove air from the cooling system?
When replacing antifreeze for a BMW or another car, the formation of air pockets is not ruled out. These are detected if the air supplied from the fan is hot when the engine is running.
When replacing antifreeze in the BMW X5 E70, you should pay attention to the air valve next to the filler neck. When filling, it is unscrewed, releasing air from the system. Also, many car owners recommend pressing the hoses with your hand, preventing the formation of air pockets.
If one is nevertheless formed, the engine is turned off and the air valve is carefully unscrewed again. Please note that compressed hot air can blow out from there. Some motorists, to get rid of air jams, let the engine run with an open radiator and expansion tank However, such measures are not always justified.
