Do not boil! Is it necessary to wash the car radiator. Flushing of the radiator: Review of funds and effective methods How to clean the engine cooling radiator

The engine cooling system, like any other constantly functioning element of the car, needs regular prophylaxis. Ignoring sediments inside the radiator and the entire cooling system can lead to deposits.

The flushing of the radiator can be carried out without problems independently using sweater and special equipment.

How does the engine cooling work?

Given the average temperature of the engine (especially with long work), its high-quality cooling is vital. The entire OS is fairly simple - tubes emerging from the radiator pass through all the vital and most warm points of the engine. Constantly circulating Tosol (antifreeze) takes over the heat to itself, in order to further pass it into the radiator of the engine cooling system.

The engine cooling radiator on the principle of action is largely similar to similar household devices. In the tank, located outside at the top of the radiator, the coolant is poured. At the top and bottom there are two nozzles, through one of which antifreeze goes to the engine, and through the other it comes back to convey the excess heat to the coolant of the radiator. Being made of material with good thermal conductivity (usually copper or aluminum), they are well taken heat from antifreeze, which has come from the engine, which is thus cooled. Transmitted heat cooler re-sent across the tubes.

Deposits and various precipitation can be formed on any element of the cooling system and radiator, so the washing is usually comprehensive. The type of possible target is strongly affected by the factory is used for cooling. Many motorists and now feed their radiator with water. Well, this is a personal choice of each, but water, and later, will certainly lead to the formation of scale. In addition, with a serious load, it will simply circulate, really not cooling anything. To avoid serious consequences, it is recommended to make preventive flushing every six months - a year. It is better to observe the schedule than to get to the repair of the cooling radiator.

Faithful signs of impending washing

As the critical point approaches, your car will be all possible methods Warning you about problems with co.

First of all, you will notice the following signs:

• The temperature of the engine will constantly recompub the normalized values. Do not notice it is difficult, because There will be constantly burning light bulbs of temperature sensors;
• If you have a radiator icon on the instrument panel, it will also burn constantly. This feature should pay attention primarily;
• Antifreeze in the tank will acquire a dirty, turbid shade. This is due to the fact that when circulating the cooler will bring not only heat, but also fragments of deposits, already densely settled in Co;
• The response to replacing the position of the rheostat will be significantly slower;
• In particularly launched cases, you can notice the growths that can be formed on the radiator lid.

How does the engine washed?

Before proceeding directly to the procedure, you need to determine the nature of pollution. If we simply have certain suspicions without explicit signs, it will work out without removing the radiator, as it comes to prevention. Cleaner of radical contaminants interfering normal work Systems, occurs with the removal of CO and careful clearance of problem areas.

Standard flushing up to medium pollution passes simply. First there is a drainage of waste toosol or antifreeze. After that, the tank is poured the selected means for removing scale and other deposits. As a rule, for flushing and cleaning cavities, it is enough 20 - 30 minutes of engine operation in idle mode. Then the means together with scale and mud merges, and distilled water is poured into the cavity. This is necessary to remove dirt residues and cleaning fluid. After that, you can fill the fresh cooler.

If you run the situation, that is, the risk of getting to replace individual fragments of the cooling system, and even entirely. If there are global deposits and obstruction, rinse the cooling radiator without removing will not work - only takes the radiator with everything due and the attempt of coarse cleaning. One of the peaks of the lesion of the system is the formation of leaks in the radiator caused by the spread of corrosion. In this case, you are waiting or full replacement, or soldering the engine cooling radiator.

Washing facilities with

Despite the good selection of specialized chemistry, many preferred very manifold cleaning methods. However, B. this caseThey work well if you know the specifics of application. In almost all methods, it turns out to be cleaned, without removing the radiator and other parts of the cooling system. In any case, it will be stopped in more detail in all possible options.

Special means

1. LAVRRadiatorFlush.. Despite the rarity of real positive feedback The quality of the products of the domestic brand LAVR, the chemistry for washing the radiator they turned out quite good. It struggles well with various types of pollution, scale, etc. According to the instructions, the agent pre-diluted with warm water should be hungry according to about half an hour. To do this, sufficiently hold the launched motor on idling. As with all other chemistry, the new cooler is poured only after washing the radiator with distilled water. By the way, most good reviews This means comes from the owners domestic cars. So, if you all break your head about how and how the BSEs of the VAZ plant are a good option.
2. HIGear.. It is considered a very good profile to clean CO. Although High Gear is made in America, his price is quite democratic to our brother. One bank will cost you no more than 400 rubles. From the main advantages of this chemistry - a record short time for processing pollution. Just seven minutes. One banks (325ml) is enough to handle the radiator with a capacity of up to 17 liters of the cooler, which makes the means suitable for passenger carsAnd for freight. According to the assurances of those who know, this chemistry sometimes copes where cheaper analogues did not bring results. And someone did not help at all. However, it more depends on the strength of the cooling system. Autochemistry is effective, but not able to create a miracle.
3. Liqui.Moly.Well, what can you say, this time the pedantic Germans disappointed slightly. Yes, the tool works, but many complain about non-retractable after a foam processing. Yes, and against corrosion, this chemistry works no matter. It is better to choose a more serious means.

Home Methods

1. Washing the entire engine cooling system lemon acid. Yes, this is a completely effective method. It will be very effective if water was used as the engine cooler, because Acid formulations are as efficient as possible against rust. The recipe is simple - forty gram of clean citric acid per liter of water. In order for the method to work, you must first warm the engine (with a pre-flooded acid), then drown out and leave it overnight. Then drain / rinse. You can meet recipes and with a greater concentration, but with strong sediments lemon acid ineffective in principle. By the way, it is possible to use phantas, it also contains acid in sufficient concentration. And precisely phantom. Coca Cola and other "analogs" will not fit. Cola can harm the radiator due to the composition features.
2. This can also be attributed acetic acid. Divide 0.5 vinegar (70%) in ten liters of water. A flooded solution to drive around from half an hour with the engine center. Then merge. After several repetitions, light pollution will wash.
3. Sodium hydroxide.Caustic soda, if for sure. The method is not bad, but you will need to clean the radiator, after removing it. The solution is prepared at the rate of 80-100g powder per liter of water (concentration of 10%). Do not bring to a boil, pour hot mortar into the engine cooling radiator and leave for 30 minutes. After draining you need to wash the cavity hot water. It will be even better if you make a burning hot air, but only against the direction of movement of the pump operation.

It is not worthwhile to wash Coca Cola and various household chemicals (including means to remove food fats.). If Fairi is simply not effective against technical fats, then Calon, moles, etc. can be fatally damage the aluminum radiator. Yes, and for copper they are not very good options.

Car radiator. Do I need to wash it?

​
Dust, sand, winter salt, insects and other debris clog the cooling radiator cells. Few people think about, but contaminated radiators can lead to vehicle breakdowns, which will be repaired by the owners in a significant amount. This problem is exacerbated depending on the complexity and modernity of the car itself. Today, most cars have several radiators in their design, including radiators of cooling systems of automatic transmissions, located in hard-to-reach places.

All the pollution listed above, scoring the cells of radiators, create a very dense layer. This layer begins to work as a kind of insulation, not allowing the possibilities of radiators to perform their immediate functions - to cool the fluid circulating in them!

This leads to an increase in the temperature mode of the engine and other aggregates. Motor overheats and can fail. How to escape from possible expensive repair? Consider this problem in more detail.

The main symptoms of the brewing problem.

Before using an expensive washing, you need to make sure of its need. Under the hood, the cooling fan is often buzzing, and there is no reason for this, it means it's time to take a look at the cooling radiator. Pollution is visible to the naked eye. Between the cells, dirt, insects and all kinds of garbage from the roads are clogged between the hundred. Most often it looks like a gray incomprehensible mass that is impenetrable for airflow.

In the summer, the cooling cell is clogged with poplar foam, grass and sticky kidneys. Under the action of high temperatures, they carve into monolith with mud and road dust. Air flows cannot break through such a pillow, and the cooling process of the motor is broken. But the worst thing happens when the winter dirt is superimposed on the all-raised poplar fluff with salt and other reagents.

Usually takes several years before the new radiator is experiencing a deficit of heat transfer. Cars risks risks for long-distance trails to the risk group. The speed is large, the spread energy with dust particles is large, the dirt deeply dugs into the honeycomb.

Large problems expect those cars who hold on the dustless wagons. Not only, from under the wheels, stones fly in a glass, so the rising dust clubs are scored not only the radiator, but also all filters. In winter, an emulsion from water, sand and dissolved chemical reagents flies. This substance listens to the radiator and literally cements the space between the cells. Under the action of the Temperature of the Zhijokokoku in solid crust. And here you should not be deceived: she herself will never fall off, careful cleaning is required.

Which exit?

The problem is that the sink of the radiator is complex technological process. Few people know that there is not one in the car, but several radiators. In addition to the major front, there is auxiliary, there is also an oil radiator and cooler automatic box Transmissions. They are deployed to incoming air flow and mounted in the depths of the engine compartment. It is hidden radiators often and are in the polluted state and are the cause of engine overheating and transmission. It is impossible to get to them without disassembling some removable parts front. This is usually a bumper, grille and other mounting devices.

Next, the most difficult thing is to: so wash the radiators so that the car does not get on the joke. Some mosters simply take "Karcher" and run a jet under pressure in 150 bar in motor compartment. Often such things are embarrassed on ordinary washers by chance hired employees. For modern car This barbaric death procedure is similar. Electronics fails, the interruptions of sensors and sensors begin. The onboard system issues errors. And these are the most harmless of the misfortune. Much worse if the jet hit the black box at the radiator hiding in itself the engine control unit. Then writing disappeared, the repair will cost several tens of thousand rubles.

The output is simple!

It is impossible to save on what directly affects the performance of your car. With cleaning radiators, it is necessary to contact the professional service center, which gives warranties on the work performed, and not on the usual sink.

Cleaning the engine cooling radiators in the Studberg technical center is only 10,080 rubles. Including air conditioning refueling.

Many often forget that in addition to oil in the engine and various filters there are still cooling system, which also needs to be regularly serviced to the engine vehicle He worked properly and as long as possible. But in contrast to the same engine, gearboxes and other mechanical parts In the car, this cooling system actually does not make any extraneous sounds. If there is no coolant temperature sensor, then you really did not know what actually happens inside the cooling system.

Cooling the car engine is carried out precisely using a radiator that acts as a regular heat exchanger placed in a machine to a specific area (place) where large air flows pass. That is why the cooling radiator plays a very important role in the work of the entire car cooling system. Well, how to be, if you were driven from within various saline and other sediments? Do I need to wash it? And what will happen if not follow the condition automotive radiator? We invite you to get comprehensive answers in our article.

As we have already told above, the cooling radiator with the help of heat exchange cools the heated antifreeze, which circulates along the cooling system. It also heats away from the engine due to the same heat exchange. As a result of this process, the engine temperature decreases. As you understand or already know that for effective cooling Engine this antifreeze Circulates by big circlepassing naturally through the radiator.

The circulation of coolant is watched by a water pump ( water pump), which rotates due to the torque of the resulting belt from the pulley, fixed on the front of the engine crankshaft.

Due to this, the water pump begins to swing the coolant faster as soon as the engine turns begin to grow. As a result, the larger the load on the motor, the faster it circulates the antifreeze on the cooling system, which makes it possible to prevent engine overheating.

In the engine cylinder block and in the radiator, metals and various alloys are present, where, as a result of the process, their interaction with coolant (antifreeze) occurs, which has a water base and always leads to chemical reaction Between them. As a result, unwanted deposits are formed in the cooling system. Therefore, if you do not serve the cooling system, it will definitely lead to serious consequences and problems with the car.

Cooling radiators in their design have horizontal plates inside which the antifreeze circulates (coolant).

Thanks to these plates, heat exchange is carried out. It is through these plates and pass the flow of cooled air that takes the heat that transfers the heated antifreeze to the plates.

Also, this antifreeze due to the content of water in it sooner or later leads to rust radiator corrosion) from the inside. That is why it is recommended to change antifreeze in the cooling system every two or three years, It all depends on the mode of using your car.

Including, even in the absence of such rust in the radiator, as a result of the chemical interaction of antifreeze with metals in the cooling system, internal passages in the radiator itself can be clogged, where the main heat exchange processes occur.

The increase in these deposits creates a thermal-non-conductive layer inside the radiator tubes and lines for which antifreeze circulates. As a result, the thermodynamic efficacy of the entire cooling system is hampered.

purpose automotive system cooling to free as much over heat from the engine and send it to environment. So, if the radiator clogs due to deposits or due to corrosion, it will certainly lead to the inefficient work of the entire cooling system and, respectively, which will be associated with the overheating of the engine.

Remember that scale in the cooling system will only increase and as a result, the cooling fluid may have obstacles to unhindered circulation in the system. This means that there will be a failure of a normal heat exchange, which will lead to the inevitable engine overheating. Of course, in this case it will be perfect if the driver notices the problem with overheating and turns off it, that is, immediately, as soon as the engine temperature is on dashboard Start rise.

Unfortunately, many drivers notice it too late. As a result, this leads to serious consequences and problems that with the cooling system itself and with the same engine.

Remember, even a short slightly overheating of the motor can lead to big problems. For example, damage to the same block head gasket.

Look carefully on deposits inside the car's radiator, the owner of which did not regularly change the antifreeze

To our happiness that you can purchase in an auto shop or hypermarket, which are able to increase the service life of the radiator and, accordingly, the service life of the engine. To do this, use the means to remove scale in the cooling system. This will help you significantly reduce the number of deposits in the radiator and in other components of the cooling system.

But you should still understand that the chemical processes that occur in the cooling system are so easy to stop, therefore, to keep the system in normal state, you must necessarily change the old antifreeze to the new antifreeze in this system (1 time in 2 years or 1 time in 3 years in the usual average annual car runs that do not exceed 40 thousand km during the operation of the car is not in a hot climate).

Here is what you have to do to independently change the antifreeze in the cooling system:

• - Wait until the engine cools after you drown out the car. Thus, you will make the antifreez replacement process safe, and all due to the fact that the cooling fluid cools.
• - Remove the radiator lid or cover expansion tankTo lower the pressure in the cooling system.
• - In the front of the car, find a drain plug of coolant, putting a container for old antifreeze.
• - Unscrew the drain plug at the bottom of the radiator. As a result, the spent coolant will begin to drain.
• - After you have merged antifreeze, tighten the drain plug in place and fill the cooling system with distilled water.
• - Turn on the engine and the cooling system itself rings water through all its components. This not only woven inside the engine and the radiator, but may also help get rid of air bubbles that can be formed in the process of draining the old and bay of new antifreeze.

Also clogging by deposits in the cooling system can be observed in the radiator's inlet.

• - Add a flushing tool into the cooling system and let the engine at idle to drive the wash fluid throughout the system.
• - Then, close the radiator cover or the cooling system expansion tank, pass a little by car high revolutions engine to quickly bring the temperature power aggregate before operating temperature (Temperature between 90 and 110 degrees Celsius).
• - Mock the engine and wait until the engine cools down. Then, drain this mixture of water and flushing fluid by opening the drain plug of the cooling system again. As a result of such a washing, you get rid of most deposits in the cooling system.
• - Then, fill in the cooling system with the finished antifreeze (or a mixture of antifreeze and water concentrate in the ratio, depending on your area of \u200b\u200bresidence).
• - Start the engine by turning on the heating of the cabin to the maximum. This will allow you to get rid of the accumulated air in the system.

Pay attention that when the old antifreeze is drained, its color is likely brown or rusty. This is due to the internal corrosion inside the engine and the metal elements of the cooling system. But as soon as you promote the system with a special flushing agent, which will go through the entire cooling system several times, then the drainage fluid becomes more transparent, and maybe in it you will find white substances that were just the deposits in the radiator and in other channels of the cooling system. .

Also in auto shops for sale and various anti-corrosion products for the cooling system itself, which you can purchase and use together with washing liquids. This will additionally increase the service life of the cooling radiator by car.

Despite the fact that the flushing of the cooling system may seem like a trivial procedure, in no case should be neglected by the owner of the car. Remember that the regular flushing of the cooling system and the frequent antifreeze replacement will actually increase the service life of the radiator and other components of the cooling system. So it is impossible to underestimate this procedure.

The operation of the car engine depends on the state of the cooling system, which is largely determined by the quality of the coolant used. Bad products contribute to the appearance of deposits on the walls of the system elements, including radiator. Over time, this layer becomes impressive and leads to a decrease in the passage of the tubes. In some cases, the car radiator partially loses its properties.

When needed flushing

In order to determine that it is time to rinse the radiator, you need to carry out a small diagnosis that is as follows:

• Evaluation of the condition of the coolant;
• Visual inspection of the radiator from the inside;
• Evaluation of the efficiency of the cooling system.

Merging the cooling fluid from the car radiator, you need to pay attention to the content in it sediment, particles and color change. A turbid having particles of incomprehensible substance, the liquid indicates that in the system on the walls, it is likely to have a scale. Although, not always even pure liquid indicates good condition Radiator from the inside.

It is possible to notice the presence of scale (sediment) at visual inspection of the radiator. This is done when the plug-in tape is removed using a flashlight. The precipitate has the property of accumulating not only on the walls, but also to a greater extent below. Therefore, the top view will not show the true state of the radiator.

The following indicator of the system clogging from the inside is the frequent turning on the cooling fan. This phenomenon may be associated not only with an increase in ambient air temperature, but also with a decrease in the coolant area of \u200b\u200bthe radiator. When some tubes are clogged, then the liquid through them does not flow and for this reason the speed of cooling the engine of the car is reduced. Thus, the fan is simply forced to turn on more often than usual to prevent temperature excess. It is not easy to notice this if the driver did not pay attention and did not compare the behavior of the fan before and now.

Rinse the car radiator can be without any specifying signs. This is done periodically. Some believe that it is necessary to carry out such procedures every 20,000 km of run. The interval in each case is quite reasonable to appoint himself. If you already had to clean the radiator several times, then guided by the information about interprokraktime, the independent definition of the period of the next cleansing is not difficult.

Funds for washing

Folk Methods

After it is decided to wash the car radiator, you must purchase necessary tool Or use those that are at hand. There are several funds:

• Milk serum;
• Pepsi or Cola;
• Solution of caustic soda;
• Electrolyte;
• Water.

There is an opinion among drivers that dairy serum is capable of qualitatively remove the deposition of the cooling system. It is poured instead of coolant and drive a certain, a few tens of kilometers a distance. After which the serum is merged from the car, and the radiator is preferably rinsed then clean water. The process of cleaning occurs due to lactic acid, which is quite safe for system materials.

Recently, a different solution appeared. Instead of brew whey, Pepsi or Coca-Coke are poured. The engine is hardened and give it to work 15 minutes. The procedure is repeated if necessary.

Some recommend rinse the car radiator with a solution of caustic soda. However, the caustic natra is able to remove not only the raid, but also to destroy the metal. Because of this, it is better not to use it as a means for cleaning.

Another means is lemon acid. On the bucket water it is necessary about 50-100 g of substance.

There are those who use the electrolyte from batteries. Much depends on the concentration, but in itself, sulfuric acid is very aggressive. Therefore, it is undesirable to apply it for such purposes, especially, given the material of the pipes.

Most. simple way Rinse the radiator is to use water. Of course, it should be clean before the fill in the system.

Special detergents

Modern auto chemicals are well developed. For a car, you can find on sale almost everything, including a means for washing the radiator.

There are many firms that produce special means for washing. The quality of their products is significantly different. Those manufactured by Hi-Gear and Kuhler-Reiniger are considered high-quality goods. For this reason, both prices are more than others. At the same time, it should be recognized that they cope with the task of cleaning very well. Buying cheap items in the store, you risk the health of the car cooling system. The desired cleansing effect in this case is also a great probability not to get, so do not save. Wanting to achieve success in delivering the system from scale, it is necessary to understand that for good quality you have to pay.

In addition to the car for the car there are other used for cleaning household, food capacities, such as teapots. One of them is Antinakipin.

It is possible to extend the time interval between the cleaning of the radiator from the inside, if you pour high-quality cooling fluid into it. Usually, it contains special additives that prevent sediment deposition on the walls of the radiator. In addition, its composition itself prevents education or precipitation.

Do not purchase goods on the road. Despite the relative low cost, they are most likely poor quality, which, in turn, can lead not only to the formation of scale, but also to the destruction of the material of the pipes.

It is better to use that coolant, which is recommended by the car manufacturer.

Well no

The operational parameters of the auto depend not only on the state of its power unit and the chassis, but also the efficiency of the cooling system. To a certain extent, this is ensured by using high-quality cooling fluids. Otherwise, in the inner walls of the heat exchanger, deposits quickly appear, which entails the loss of its heat-conducting properties.

When should I do flushing?

Before cleaning the car radiator, a simple inspection should be conducted, which will allow to assess its degree of contamination:

• Evaluation of the efficient cooling system.
• Checking the condition of the coolant (coolant).
• Inspection of the inner part of the heat exchanger.

The first thing that owes a car owner is a frequent inclusion of the forced cooling fan. The reason is the reduction of the cooling area, the fluid flow is reduced due to the fact that radiator tubes are clogged with outsiders. It is also possible to clog the outer plates with dust or insects.

During drain, the coolant must pay attention to the presence of foreign inclusions in it, as well as to change its color. About scale on the walls of the radiator node testifies the sediment or small particles.

The visual inspection of the inner part of the heat exchanger also allows you to determine the presence of scale. It is performed using an electric lamp when the neck stopped. However, this method can hardly be called efficient, because the precipitate is more accumulated at the bottom. Therefore, any motorist interested in the question, as and when to clean the car's radiator, should understand that the top of the top will not reveal the true state of the aggregate.

Experienced car owners are washed with a heat exchanger even in the absence of listed features. The procedure is carried out on average with a frequency every 20 thousand km of run, but the interval can be shifted depending on the quality of the coolant. If you already had to clean the radiator node several times, then the schedule of work will not work.

Make yourself: how to clean the contaminated car radiator from the inside?

If the external cleaning of the heat exchanger can be directly on the machine without resorting to its dismantling, then for the inner washing it is necessary. The removal process is accompanied by the execution of the following items:

• Under the radiator valve, install a suitable container.
• Unscrew the throat lid.
• Release the valve on the cylinder block and drain the coolant.

To clear the insides of the heat exchanger, you need to send a dense stream of water in its neck. All extraneous particles and precipitate will go through the lower nozzles. The procedure should be repeated several times. In case of severe pollution, the use of special cleaning fluids is permissible.

After carrying out and installing the radiator, you need to get rid of aerial traffic in system. To do this, you should start the motor and give it to work about 15 minutes with an open neck heat exchanger, then turn on the heater to the maximum. A simpler way implies the installation of the front wheels of the car on the elevation with the subsequent engine start for 2-3 minutes.

What means are used for cleaning?

Auto chemical manufacturers have mastered a fairly wide range of car care products. Many firms offer special means to clean the radiator assembling system. Quality is distinguished by products under stamps:

1. Liqui Moly.
2. Hi-Gear.
3. Kuhler-Reiniger.

The price of these products is quite high, but the effect of their use will cover all the wretches. For those who still do not know how to properly clean the radiator of their car, it should be noted that inexpensive drugs are not only well coped with the task, but they can harm the heat exchanger. As an alternative, some use the domestic product Anti-Nakipin.

Folk remedies

Folk crafts claim that they managed to achieve a positive result without special costs with the help of available funds:

1. Pepsi Cola.
2. Dairy serum.
3. The solution of caustic natra.
4. Weak electrolyte solution.

The use of serum is practiced by drivers since the absence of auto chemicals. It is poured into the radiator and pass about 20-30 km, after which the solution is merged, and the insides are washed with water. With the advent of Coca-Cola, the craftsmen involved in the process and this product. It is poured and allowed to work the engine for 15 minutes.

The expediency of the use of caustic soda causes some doubts, since its elements are capable not only to remove the flare, but also to destroy metal parts. The same attitude of the specialists also causes the use of electrolyte, whose nature is too aggressive and is able to harm rubber products.

Lemon acid as a means is suitable to a greater extent, it is necessary for the water bucket of it 60-100 g. These alternative substances are eliminated from the need for dismantling work, but the products of their activities in the form of individual particles may prevent the thermostat functioning.

conclusions

The main complexity of cleaning lies in the nature of the deposits on the inner surface of the heat exchanger. All who are wondering how to clean the radiator personal car, are obliged to know the fact that corrosion and scale are effectively removed by solutions with an acidic medium, and products decomposition of antifreeze of oil-fat nature - alkaline compositions.

Increase the interval between procedures only if you use a high-quality liquid that contains additives that prevent the formation of a harmful precipitate. Acquire a dubious product extremely undesirable - this can lead to expensive repair of the entire engine.
