The car and the cooler have a different purpose and should not be mixed. However, sometimes anticipation of antimony into the oil (and vice versa). Because of this, the motor begins to function incorrectly.

To prevent negative consequences of antipaths into the oil, rearing the problem in a timely manner, you need to understand what the signs of the availability of the cooler in the lubricant.

Why the cooler gets into the car

The reasons why Tosol went to the oil may be as follows:

Purchase spare parts only in reliable outlets. Do not resort to car service services in which employees work whose qualifications are questionable.

Automobile in antifreeze

It happens the opposite. When motorists see traces of lubrication on the walls of the expansion tank, they ask themselves the question: "Why oil in Tosuole?". Machine from the lubricant complex is somehow in the cooling system, while everything is fine with oil fluid. Its volume, shade, viscosity does not change.

Moving experienced drivers in such situations say: "End to the cylinder block". Usually these words correspond to reality. After a crack in the block, part of the lubricant falls into the cooling complex, turns out there. Emulsion is formed. Replace the cylinder block on its own almost impossible. You must contact a specialized service center.

Signs of antifreeze in the machine

How to determine what Tosol got into a lubricating complex? It is possible to understand this in such signs:

If you find that the cooler goes into the lubricant, turn off the motor and find out the cause of leakage. Otherwise, you will probably have to capitalize the internal combustion engine.

What actions to do?

First of all, find out why Tosol began to flow into the car (how to find out the cause was written above). For the most part, you need to change the lining by checking the motor spare parts. If the block head is in a normal state, does not have noticeable cracks and shells, then repair will cost inexpensively. In the presence of strong deformation, you will need to change the exhaust item. Remember that repairing a broken block head is meaningless. It's easier to replace it with another.

After you remove the main reason, completely rinse the cooling and lubricating complex. It will take to disassemble the nozzles, clean the maslochannels. It is quite difficult. The mixture of the cooler and lubrication is not so easy to eliminate with spare parts. Use the washing agents by which the motor is brushed from a variety of contaminants.

Rolled oil in Tosuol adversely affects the operation of the engine. Bearings are locked, the lubricant is deposited on the spare parts, the corrosive effect is enhanced. If you ignore the problem, the power unit will occur, it will take a major overhaul.

By purchasing a vehicle, prepare for what you will need to carry out my own. All recommendations are written in the operational manual. Understanding how the car is arranged, you are unlikely to Nalte Tosol into a lubrication complex.

Similar knowledge come with experience. The more experienced driver, the more procedures he can perform independently. This makes it possible to save own money, as it is not necessary to pay for the work of service of car service.

In order for your vehicle to serve you at a maximum of a long time, follow the recommendations that the automaker in the operational manual prescribed. Pour into the motor only those consumables that are optimal for your power unit. If you find it difficult to choose the optimal cooler / car, contact your experienced driver or to the service center employee. Competent maintenance of the car is a guarantee of a long operation of the machine.

During checking the level of antifreeze, the car owner can detect engine oil in the very seemingly unexpected place - an expansion tank. Its neck will be smeared with lubricating composition, and the coolant itself will change color, consistency and acquire an unpleasant smell.

This problem is most often in American and domestic cars. However, its appearance is not excluded in systems of other foreign cars.

What is the reason for such an unpleasant breakage, what is it dangerous and how to eliminate it? Let us dwell on each question separately.

Both liquids - and cooling, and lubricating - circulate in a car in different systems, independently of each other. They perform different functions, so insion should be provided inside the engine. If the problem of mixing engine oil with antifreeze, the driver must understand that this is possible only when system is deployed.

It happens for the following reasons:

• disorders in the operation of the oil radiator;
• mechanical damage to the head of the cylinder block, heat exchanger gasket;
• the destruction of the nozzles through which the coolant passes;
• the occurrence of cracks and other defects on the expansion tank;
• the arrival of the cooling system inductance.

In addition to the listed reasons, the use of incorrect refrigerants can cause damage, namely: their mixing. Each coolant has its own classification. Each of them has different properties and consists of certain ingredients. In the interaction of incompatible additives, an uncontrolled chemical reaction may begin, which will cause depressurization of the system. Therefore, before pouring a new antifreeze into the car, it is necessary to merge the old liquid.

Please note that the color of the coolant does not characterize the class to which it relates. This is just a dye that adds a manufacturer. Therefore, do not try to mix two, say, the red cooler, relying only on their visual similarity.

Is the breakdown?

Any malfunction in the car, even if the most insignificant, should be given for more attention, because it can provoke the appearance of a more serious breakage. Ignoring the fact of mixing lubricating and cooling liquids does not succeed anything pleasant: in a short period of time, corrosive processes are activated inside the motor, the throughput capacity of the oil filter will be activated.

It is the oil filter that will first accept the "blow of unhappiness", but if it is possible to notice the oil in the expansion tank in time, then you can do with small victims. When replacing the coolant and washing the system, it is recommended to contact the car service.

First, they can easily find the cause of leakage, secondly, they will produce a really high-quality cleaning of cooling channels. If you decide to save and conduct a procedure yourself, then keep in mind: the incomplete washout of oil from the expansion tank will continue to be clogged. And in the accelerated rhythm.

As practice shows, more than 30 percent of cases associated with the failure of the motor system causes a similar problem. Due to the interaction of chemical elements included in the composition of lubricant and cooler, a stormy chemical reaction occurs that even metal parts are corrosive. As a result, two systems come out at once.

How to determine if the oil falls into the expansion tank or not?

As mentioned earlier, the dirty neck of the capacity and the change in the structure, odor and the color of antifreeze indicates the presence in the expansion tank. But these are not the basic symptoms of breakage. It can be determined by the following factors:

• during the drain of the coolant, its condition is not in doubt, but at the end of the procedure from the system begins to flow out a dark color, having a sharp odor;
• inside the expansion tank may begin to settle soot;
• the level of antifreeze is quickly reduced.

There is another kind of way to find out if the oil appeared in the cooler. To do this, take a small piece of clean fabric, dip it in antifreeze, filled into the expansion tank, and try to set fire. Does not burn? It means that only refrigerant is present in the system. If there is even a small light, you can be sure - the oil fell into the cooling system.

Debugg

Why a similar problem appears, and to which consequences it leads, figured out. Now it remains to understand how to eliminate the breakdown and prevent its re-appearance.

The elimination of motor oil is complex, which requires care process, which most often requires replacing the gasket of the oil cooler.

To carry out this manipulation, you will need:

• distilled water (10 liters);
• antifreeze for replacement;
• capacity for draining spoiled coolant;
• laying the oil cooler. Do not attempt to clean the old and return it to the previous place: after interaction with unwanted chemicals, she lost its properties;
• special detergent.

Because Oil appears in the cooling system in many vehicles, find special means to eliminate it in any auto shop. The main thing, do not try to purchase the cheapest drug - it will not be able to completely remove the oil fluid from the internal surfaces of the system.

The procedure for replacing the gasket of the oil cooler is quite simple: you must first dilute the existing refrigerant with detergent and give the engine to work with such a liquid for 10 minutes. Then you need to unscrew the drain plug of the cooling system and wait for its complete empty.

After that, we make installation of the oil cooler, cleaning it, replacing the gasket. Next, remove the expansion tank and thoroughly rinse it from oil residues.

Once all the manipulations are made, all the elements of the system should be collected and proceed to several flushes using distilled water.

If during these events you noticed cracks, chips in detail and understood why oil gets into the refrigerant, it should immediately replace a weak element to prevent repeated mixing of liquids.

To avoid a similar problem, the driver should regularly carry out the maintenance of the vehicle and carefully check the condition of vital systems. If you doubt your own opportunities, it is advisable to entrust the work of professionals. But in no case cannot ignore the problems that have arisen.

And finally

It is impossible to completely protect your car from breakdown, because they appear at the most unexpected moment, and sometimes they can only guess. Nevertheless, the motorist can reduce the risks of the emergence of unpleasant situations if it is more careful to handle the car. In cases where the oil falls into the cooling system, it is clear that the blame of this is depressurization. And to avoid repeat, first of all it follows this depressurization to eliminate.

As you know, any modern internal combustion engine requires good lubrication of those parts that are friction, as well as high-quality cooling, providing timely removal of unnecessary heat. For this, the motors are equipped with oil supply systems and antifreeze, and they are arranged in such a way that the fluids circulating over them are not mixed.

However, it often happens that, when checking the level of coolant, motorists detect a major change in its consistency and color. This suggests that it still got a lubricant, and the problem requires a speedy solution. In order to eliminate it, it is necessary to accurately establish why the oil falls into antifreeze.

The lubrication and cooling systems of internal combustion engines are not only not related to each other, but also sealed. Therefore, if it is found that in the coolant still there is oil, it is quite logical to assume that it fell there due to depressurization. In practice, it is in the overwhelming majority and sometimes, and direct causes of lubricating fluid to the coolant liquid are:

• Malfunctions of the cylinder head;
• Pump worniness;
• Cracked heat exchanger gaskets;
• Cracks of the expansion tank;
• Oil radiator problems;
• The failure of the cooling system nozzles or lubrication system.

Since there are channels in the cylinder head, which should be coolant, then by microcracks appearing in it as a result of shocks or for other reasons, oil without problems can penetrate antifreeze. Pump wear is manifested, among other things, in its depressurization, which also can lead to ingestion of its lubricating fluid. The cracks of the gaskets of the heat exchanger, the oil radiator and the expansion tank also serve as the "expansion" oils in the oil, as well as the failure of the cooling and lubricating systems.

How to determine antifreeze in oil

Oil in antifreeze

As mentioned above, most motorists discovers that oil fell into antifreeze, when the coolant level is checked. However, there are other symptoms that such a non-disabilities occurred. One of them is that when removing antifreeze, the last few of its milliliters turn out to be too dark, they have a more dense consistency and they are not so easy to merge from the tank. The fact is that because oil and toosol have different viscosity and density indicators, they do not mix with each other. Lubricating fluid is easier, it floats up and therefore follows the latter.

Another sign that the antifreeze is lubricant, is that it becomes flammable. Check it is very simple: you need to get into antifreeze with a regular paper napkin and try to set fire to it. If it succeeds, then oil got into antifreeze, because he does not burn in itself. It goes without saying that, by conducting such an experiment, you need to move away from the car for a considerable distance.

Quite often, the oil fell into antifreeze, it is possible to determine according to the state of the oil filter. It is faster than usually, fails, its throughput is reduced, and the car begins to test "oil hunger". The fact is that when attaching antifreeze to the oil, sufficiently dense small balls are formed, which "clog" filter.

Possible consequences of oil from antifreeze

If it is established that oil falls into antifreeze, then it is necessary to eliminate this problem as quickly as possible, since it can lead to very serious consequences. Since the tightness of the lubrication and cooling systems of the power unit is broken, the antifreeze is contaminated with oil, and the oil - antifreeze.

Both liquids contain many different additives in its composition, most of which are chemically active substances. What kind of reactions will occur between them, it is impossible to predict, but it is completely unambiguous that they will lead to a significant reduction in quality and oil, and coolant. As a result, the work and system of lubrication and cooling systems are seriously deteriorating. Most of all, the practice shows, bearings suffer, in addition, the risk of engine jamming significantly increases significantly.

It should be noted that oil getting into antifreeze and antifreeze into oil is most dangerous for diesel power units. The fact is that it leads to corrosion of the walls of cylinders, and as a result, when the cooling engine is turned off and the cooling engine, antifreeze penetrates in the combustion chamber. Further, when the motor starts, the so-called hydraulic blow occurs, the power unit encourages and it requires a complex, expensive and sufficiently long-term repair.

What to do if oil found in antifreeze?

In the event that it turned out that oil fell into antifreeze, it is best to contact the maintenance station. Its specialists will diagnose, accurately determine the cause and eliminate it. However, what exactly it would not consist, the masters necessarily solve both fluids, because none of them can fully fulfill its functions.

After that, the engine cooling system and its lubrication system must be washed. This is necessary to remove those contaminants that are certainly available in them. In addition, the oil filter is replaced. In the process of eliminating this problem, it is almost always replaced with a new gasket of the cylinder head, the pump, thermostat and nozzles are thoroughly washed. If it turns out that the heat exchanger is "to blame" the cooling and lubricant liquid, it is washed. In addition, gasket gaskets are replaced.

Thus, oil entering antifreeze requires a whole complex of repair and preventive measures. It is necessary to implement them to avoid the emergence of truly serious problems with the engine.

Video on the topic

With this problem, many motorists are facing such as owners of foreign cars and drivers of Russian cars. In our article, we will describe in detail about the causes of this problem and the methods of eliminating it.

How to determine autolant in the coolant?

Usually, the motorist will learn about this problem when trying to check the amount of antifreeze in the liquid cooling system. You should alert:

• the appearance on the walls of the Tank Tank Tank So-called Emulsion (the result of the oil connection with Tosol);
• outflowed oil film on the surface "Tosola";
• change its color and the appearance of unpleasant odor.

The experienced drivers advise to lay the napkin in the tank and feed it, the presence of traces of oil will immediately give themselves to know: it will light up, and the pure antifreeze is not lit. Just do not forget about security measures! And also this can be checked by lowering the probe into the container with the refrigerant. Putting a brown pulling mass on it signals that it is necessary to start repairing.

It should be noted that these fluids proceed through different hermetic systems, and their compound signals the integrity of one of the systems. Therefore, tightening with repair can lead to clogging of the radiator, overheating and engine breakdown and other sad consequences.

Why did the oil in antifreeze appear? There are several reasons for this. Frequently found and most obvious causes of this malfunction.

Mechanical damage to the heat exchanger gasket.

Since the oil pressure is higher than in the cooling system, the oil can penetrate the heat exchanger. Its gasket can be worn, this ended its life, hardening or breaking. Since it will not be possible to restore it, it should be replaced. To do this, make the following actions:

• Drain the spent antifreeze from the radiator and the engine in the pre-prepared any used container, for example, an old bucket or pelvis. Substitute it under the bottom of the car to the place where the drain plug of the radiator is located, unscrew the cork or special. Cranic and drain liquid.
• You can use a special solution for washing cooling systems, which is sold in the store. After the tool is flooded into the tank, you need to warm up the motor to the desired T until the cooling fan earns. After 10-15 minutes, drown out the engine, giving it a little cool, and merge the waste fluid again.
• Remove the heat exchanger behind the collector. Methods for its dismantling you can see in the instruction manual for your car. After dismantling, you need to clean the spare part and replace the gaskets and sealing rings on the tubes connected to the aggregate. Gaskets Buy those that are suitable for your vehicle.
• After replacing the seal, remove the expansion tank and rinse it thoroughly. If it is not completely laundering, you can buy a new one.
• When all manipulations are done, rinse it several more times with distilled water in the amount of 10 liters. It is necessary to pour water very carefully so that it does not get into the nozzles and the air traffic jam is not created. Screw the tank tube and start a car, warm the engine for a few minutes so that the fan earned and left all the air. After draining distillate into the substitute substituted under the bottom. This procedure is repeated to complete water purification, finish when a transparent distillate will appear.
• In the purified tank, pour fresh refrigerant. When it is selected, it is necessary to rely on the recommendation of the car manufacturer, try not to save on quality.
• After these manipulations, you need to remove the air remaining in the tank. Ask a friend to sit in the car's salon and put pressure on gas strongly, at this time you need to push the tank pipe, while its cork should be tightly screwed. Then open the lid and shut the air.

Cylinder Block Damage, Head Crack or Wearing GBC Gasket

One of the signs of the presence of this problem will be the emergence of gases in the cooling system, the flow of motor lubrication into the cooling system and the formation of condensate in the exhaust pipe. All this indicates that the seal is broken. To eliminate this malfunction, you need to replace the old gasket.

So, proceed to the disaster. First of all, you need to de-energize the mechanism, disconnecting the ACB housing. Then drain the dirty toosol, as in the first case, substituting any container under the bottom. All work should be done when the motor is turned off! Next, remove the timing belts, high-voltage wires, then tube, nozzles and all elements attached to the head of the block.

Open the cover of the GBC. After that, make a replacement of the seal, and for greater strength to change all the fastening elements. When replacing the part, carefully inspect the block head and the cylinder body body for the absence of cracks, dents and other deformations.

You can make the assembly and disassembly of the engine both independently and in the car service.

Filling of the low-line refrigerant or antifreeze mixing of different classification

There are such cases when the driver, noticing the low level of coolant in the tank, floods the first antifreeze there. This can not be done in any way! It is impossible to mix the refrigerant, differing in the composition and class.

There is a certain classification of refrigerants - G11,12,13, they all differ in terms of cost and quality. Some mistakenly think that you can mix the antifreeze of the same color, but it is not. Color Co. gives a dye, which producers add there.

Additives added to antifreeze, when connecting its different species, may be incompatible and when heated to enter into a chemical reaction, the consequences of which will be unpredictable.

Conclusion: Use only tested and recommended auto manufacturers.

Motor oil and coolant in the proper operation of all car units should not be intersecting. They circulate on closed circles, each performing their work. But upon failure of some elements, the driver may, with the next check of the level of antifreeze, find that oil traces are located in the tank. Oil hit in Tosol is not a normal situation for the car. If a similar problem occurs, you need to know what it is connected with, and after eliminate it.

How to determine what oil got into antifreeze

Most often drivers later learn that in their car the oil falls into antifreeze. At the same time, the problems due to which the fluid circulating in closed circles is mixed, very significant. For example, such a problem may be observed due to damage to the cylinder head laying or due to depressurization in the heat exchanger gasket area. Also, oil in the toast can indicate that the oil radiator is damaged and it is necessary to urgently replace or repair.

The fact that oil particles are present in antifreeze, the following symptoms say:

It is worth remembering that not only the oil falls into the toosol, but, on the contrary, the coolant particles are crushing into the lubrication element. This leads to the fact that, together with oil into circulation, small antifreeze particles are sent in a circle, which is capable of accelerating the process of corrosion formation on the engine elements. Also, due to mixing liquids, the oil will partially lose its properties.

What to do if the oil falls into antifreeze

If the cooling fluid and engine oil are mixed, it is necessary to act immediately after the problem is detected. Most often it is associated with wear or damage to the oil cooler laying. It is not possible to restore the sealing element, so it is necessary to replace it.

To replace the gasket of the oil cooler, you need to do the following:

If the replacement of the gasket of the oil cooler did not help and the oil continues to fall into antifreeze, you can try or contact the service center.
