Than rinse the car radiator from the inside. Cleaning of the radiator - Synonym for stable operation of the car engine: guide for teapots

29.10.2019

Question, than rinse the engine cooling system, Interested in car owners who collided with problems. There is both folk detergents (citric acid, dairy serum, "Coca-Cola" and other) and modern technological compositions. We will stop more about those and other options.

Tools for cleaning the cooling system from oil, rust and deposits

How often do flushing

Before we proceed to the direct description of certain funds, I would like to remind how important it is to make a regular flushing of the car cooling system. The fact is that, depending on the coolant used on the walls of the tubes, of which it consists, rust accumulates, oil sediments, antifreeze decomposition products, as well as scale. All this leads to difficulty circulation of coolant and decrease in heat transfer. And this always badly affects the characteristics of the engine and increases the wear of its individual parts with the risk of their premature failure.

Dirty radiator

It is worth noting that the washing of the system can be both internal and external (external cleaning implies the radiator washing outside from the particles of dirt, dust, insects on its surface). It is recommended to make the internal flushing of the cooling system at least once a year. It is best to do this in the spring when there are no frosts, and ahead of the hot summer is to come.

On some machines on dashboard There is a light bulb with an image of a radiator, the luminescence of which may indicate not only about lowering the level, but also that it is time to change. This can serve as a signal and to the fact that the cooling time of the cooling system has come. There are also a number of indirect signs of the onset of such cleaning:

Radiator icon, signing about problems in the cooling system

  • frequent engine overheating;
  • problems in the work of the pump;
  • slowing the response to the rigging signals (inertia);
  • indications high temperatures from the corresponding sensor;
  • problems in the work of "stoves";
  • the fan always works on high revs.

If the motor is very hot - then it's time to pick up the tool in order to rinse, and choose time and opportunity for this.

Folk detergents of the cooling system

As we indicated above, there are two types of washing products - folk and special. Let's start with the first as cheaper and checked.

Lemon acid

Using citric acid to clean the cooling system

The most common lemon acid, divorced in water, can clean the radiator tubes from rust and dirt. It is especially effective in case of conventional water as a coolant, since acid formulations are effective against rust, and alkaline - against scale. However, remember that citric acid solution is unable to remove significant pollution.

The composition of the solution is the following - 20-40 grams of matter dissolve in 1 liter of water, and if the contamination is strong, then the amount of acid per liter can be increased to 80-100 grams (a larger volume is created in a similar proportion). An ideal option is considered when with the addition of acid into distilled water pH level is located in the area 3.

The cleaning procedure itself is simple. It is necessary to merge all the old liquid and pour a new solution. Next you need to warm up the engine to the operating temperature and leave it for several hours (and better at night). Next drain the solution from the system and look at its condition. If it is very dirty, then the procedure needs to be repeated 1-2 times until the fluid is quite clean. After that, it is necessary to rinse the system with water. Next, pour the tool that you plan to enjoy as a coolant.

Acetic acid

Using acetic acid for cleaning the cooling system

The effect of this solution is similarly described above. Acetic acid solution is perfect for flushing the cooling system from rust. The proportions of the solution are the following - half-liter vinegar on the water bucket (10 liters). The cleaning procedure is similar - we drain the old liquid, pour a new one and warm up the machine to operating temperatures. Next you need to leave the car with a running engine for 30-40 minutes So that chemical cleaning occurred in the radiator. Next, you need to merge the cleaning liquid and look at its condition. Repeat the procedure until the fluid becomes clean. Next, it is necessary to wash the system with boiled or distilled water, after which it is planted to pour the coolant that you plan to use on an ongoing basis.

Fanta.

Using phantas for cleaning the cooling system

Similar to the previous item. However, there is an important difference. The fact is that, unlike Coca-Cola, where orthophosphoric acid is used, in "Phanta" used lemon acidwhich has a smaller cleansing effect. Therefore, some car owners for cleaning the cooling system pour it instead of antifreeze.

As for the time, during which you need to ride, it all depends on the degree of contamination of the system. In particular, if it is not very contaminated, and cleaning is done more for prevention, it is enough to make the engine for 30-40 minutes on idling. If you want to wash the forged dirt well, you can ride so 1-2 days, then pour a distillate to the system, ride more, merge it and look at his condition. If distillate dirty - repeat the procedure until the system is cleaned. At the end, do not forget to rinse it well and pour a new antifreeze.

Please note that if there are minor holes or cracks in the stove pipeline, but the dirt "tightened" them, then when washing, these holes can open and flow.

Milk Acid or Serum

An excellent option for washing the cooling system of the car engine is lactic acid. However, a significant problem is the fact that it is very difficult to get a milk acid today. But if you manage to get this substance, it can be poured into the radiator in its pure form and for some time to ride on it (or give the car to stand up with a running engine).

More affordable alternative lactic acid is dairy serum. It has similar properties for cleaning the radiator and other elements of the cooling system. Serum using algorithm:

Use of lactic serum

  • prepare in advance about 10 liters of serum (preferably home, and not from the store);
  • strain the entire bought volume 2-3 times through gauze in order to filter large slices of fat;
  • pre-from the radiator merge the coolant existing there, and to pour serum to its place;
  • drive with her kilometers 50-60;
  • serum is needed in hot, so that the dirt does not have time to stick to the walls of the tubes ( observe Caution!);
  • give the engine to cool;
  • pour into the radiator pre-boiled water;
  • run the engine, give it to warm up (about 15-20 minutes); merge water;
  • give cool engine;
  • pour antifreeze that plan to use on an ongoing basis;
  • release air from the system, if necessary, add the cooling fluid.

Please note that serum has its cleansing properties within 1-2 hours. Therefore, those mentioned 50-60 km must drive during this time. It makes no sense longer to ride, as the serum is mixed with mud located in the system.

Caustic soda

This substance in the people is called differently - sodium hydroxide, "caustic alkali", "caustic natter", "caustic" and so on.

The substance can be used only for cleaning copper radiators (including for the stove radiator). Soda can not clean aluminum surfaces.

In accordance with the official instructions of the manufacturer of copper radiators, it is necessary to act on the following algorithm:

Caustic soda

  • remove the radiator from the car;
  • rinse its insides with simple water and bleed with compressed air (not exceeding the pressure of 1 kgf / cm2) to the state when clean water will flow out of the radiator;
  • prepare about 1 liter of 10% of the solution of caustic soda;
  • heat the composition at least to + 90 ° C;
  • pour the cooked composition into the radiator;
  • give him broken 30 minutes;
  • drain the solution;
  • for 40 minutes, flushing the insides of the radiator with hot water and blow by hot air alternately (at the same time the pressure should not exceed 1 kgf / cm2) in the opposite direction of the pump operation of the pump.

Remember that the caustic soda causes burns and corrosive live fabrics. Therefore, it is necessary to work on the street in gloves and the respirator.

As a result chemical reaction White foam may appear from the radiator pipes. If this happened - do not be scared, this is a normal phenomenon. The tightness of the cooling system after cleaning must be carried out on a cold engine, as hot water evaporates quickly, and find an alleged place of leaks will be problematic.

Among the so-called folk agents there are a number of such that are not recommended for use, despite the fact that some car owners still use them, and they even help them in some cases. We give a few examples.

Coca-Cola.

Use Coca-Cola as a cleaner

Some motorists in order to wash the cooling system from oil, emulsion, scale and rust use Coca-Cola. The fact is that in its composition there is orthophosphoric acidWith which you can easily get rid of these contaminants. However, besides the acid, there is a large amount of sugar and carbon dioxide, which can lead to certain problems.

If you decide to use the "Claus" as a cleansing fluid, it is better to pre-release carbon dioxide from it so that in the expansion process it does not harm individual engine nodes. As for sugar, after using fluid, it is necessary to thoroughly rinse the cooling system with conventional water.

Also, remember that orthophosphoric acid can harm plastic, rubber and aluminum parts of the cooling system. Therefore, the "Cola" can be kept in the system no longer than 10 minutes!

Fairy.

Some car enthusiasts for washing the cooling system from oil use the popular household fatty cleaner Fairy or its analogues. However, its use is associated with a number of problems. First, its composition is designed to combat food fat and with motor Oil He simply will not cope. And even if you try to pour it into the radiator, you will have to pour and "boil" the engine is several tens of times.

Calgon and its analogues

"White"

The peculiarity of "whiteness" is that it has sodium hypochlorite, which corps aluminum. And the higher the temperature of the fluid and the working surface, the faster corrosion occurs (according to the exponential law). Therefore, in no case do not pour into the system various means to remove stains, especially those where there is a chlorine and connection based on it (including Mr. Muskul).

"Mole"

Known in narrow circles "Mole" is performed on the basis of caustic soda. Accordingly, they can not be treated with aluminum radiators and other surfaces. It is only suitable for cleaning copper radiators (in particular, the stove radiators) and only removing it, under the system, such a cleaner you will kill all rubber glands and seals.

Other mixes

Some cleaning motorists use a mixture of citric acid (25%), soda (50%) and vinegar (25%). However, we do not recommend that you also do, since it is very rude and corrosive rubber and plastic parts.

These cleaning products are permissible only if you need to rinse the stove radiator and you do not provide to drive fluid throughout the cooling system.

Special fluids for flushing radiator

The funds listed above, of course, can be used to wash the radiator and the cooling system of the car, but they have already outlived themselves both morally and technologically. Currently, auto chemical manufacturers offer consumers a wide range of various cleaning products, which are quite reasonable money, that is, available to an ordinary car owner.

Types of liquids

There are several types of cleaning fluids for radiators that are divided into chemical composition. In particular:

  • Neutral. Such liquids do not contain aggressive substances (in particular, alkalis and acids). Therefore, they are not able to launder significant pollution. As a rule, neutral compositions are used as prevention.
  • Acidic. As it is clear from the name, the basis of their composition is different acids. Such fluids are excellent for cleaning inorganic connections.
  • Alkaline. Here is the base - alkali. Great to eliminate organic pollution.
  • Two-component. They are produced based on both alkalis and acids. Thus, they can be used as a universal cleansing agent to rinse the cooling system from scale, rust, antifreeze decay products and other connections.

Do not use two different means at the same time. Limit one! Also, do not use very concentrated alkaline or acidic compositions, as they can damage rubber and plastic elements of the system.

Popular liquids

We present for you an overview of the most popular liquids in our country for flushing the car cooling system, as well as some reviews of motorists that used one or another liquid. We hope that the information below will be useful for you, and you will know the better to wash the cooling system.

However, we stopped only on more popular of them, as they have proven themselves better than others. Any of the listed means can be used to flushing the system, for example, when oil fell into antifreeze.

conclusions

As you can see, the choice of means for cleaning the OS is quite wide. We recommend that you use professional means, not various folk methods that use what to wash the engine cooling system at home, when there is no possibility to buy special means. So you will save the cooling and other systems of your car from possible breakdowns and extend their life. Since different acids corrode not only the sediment, but some components and part of the OS.

Also remember that if you want to move from one antifreeze brand to another, then you need to rinse the cooling system with clean distilled water. This is the easiest and most cheap method of preventive cleaning OS.

The radiator is one of the most important elements cooling systems vehicle. Due to the peculiarities of this design and its location, this element needs systematic care. If the device is clogged with a radiator, and in time it is not cleared, it may cause increased engine wear internal combustion Because of its overheating, as a result, the repair will cost a motorist round sum.

It is important to notice that for the motorist will not make big problems to inspect this device. It should be easier at each opening of the hood to pay attention to the external state of this easily accessible element. Even a person who is a newcomer in a manual will be able to understand how much the radiator device has succumbed to pollution. Quite often, to enhance the protection of this device, motorists resort to the use of fine steel mesh on the radiator grille, which is sold in almost any automotive store.

It will be quite difficult to determine the malfunction of the radiator, which lies in the most depths of the system, namely, on the inner surfaces of the device. Nevertheless, in order to determine this kind of pollution of the car owners invented a fairly simple way. which is clean inside, will warm evenly throughout its area. In the case when one of the sites turns out to be scored, it will be possible to determine it to the touch. With all this, it should be remembered that this procedure can be made only when the internal combustion engine is only warmed, and the liquid only began its circulation by big circle. Otherwise, when the radiator is going to check due to a long crossing, you can get serious burns.

An excellent protection can be established on the outer surface of the radiator of a small mesh, which will prevent the flying dirt, poplar fluff and insects into the device. The grid itself, which is hidden behind the bumper, will not in whitly will not spoil appearance vehicle and will be enough to reliably protect the surface of the radiator from the introduction of "foreign" items. Installing this kind of grid can be produced in almost any car service.

1. How to choose a radiator cleaning agent?

It is important to notice that the cleaning of the radiator can occur in many of the most diverse methods. Recently, the largest radiator was obtained with a special means. In order to independently clean this device, it is necessary to have time and elementary desire: the entire wash procedure will be carried out as much as possible during an hour. In addition, it should be previously determined which gadgets will be needed by a motorist for all operations.

It is important to note that during the procedure of independent cleansing of the radiator, motorists often use such components and tools:

- distilled water;

Antifreeze;

Special cleaning fluid (price corresponds to quality);

Working gloves;

Rubber tube;

Soap water in a basin;

Waste container;

Different rags;

Safety glasses;

Screwdrivers and wrenches.

The easiest method provides for the use of conventional distilled water and antifreeze, by means of which the radiator will be the best way to be cleared of all contaminants.

Special means - a new branch in the development of the cleaning of the radiator. These fluids have definitely high quality, through which the motorist is most purified as possible. It is important to note that such funds are very popular, and the fakes in automotive stores are practically not found. When acquiring such a fund, pay attention to the composition and consult directly with the seller. From automotive chemistry, professional motorists prefer soft tools, since too hard fluids contribute to the destruction of the structure and surface of the device, and the inner part.

New "unique" motorists are resorted to the use of cleaning Coca-Cola and citric acid, which is poured into the cooling system with water and drive on the engine, which is heated.

2. How to clean the radiator?

All outdoor dirt that accumulates directly between radiator cells is a barrier that prevents its cooling. It is she who will lead to an increase in the temperature of the cooling fluid and overheating the internal combustion engine. Washing the radiator with water and under pressure should be carried out at least from a distance of 15 cm. The water pressure should be reduced to a minimum.

In order to clean the finishes of the radiator, a variety of ways are used, such as the above. This method is quite effective, although it will require special caution. It depends on the fact that Karcher type equipment, which is necessary for carrying out this procedure, can be used by the water pressure of the radiator. Quite often, it happens that in the old radiators of fins are destroyed, and the tubes are knocked out due to such washing. That is why special care and accuracy during washing this device is necessary.

In order to wash the radiator and the entire cooling system of the car, you should use a different kind of special compositions that are poured or falling asleep into the working system immediately before the trip and operation of the vehicle. However, using these liquids is necessary with extreme caution. The most efficient way of flushing the radiator will soak the part that was previously dismantled, in the bath with the desired detergent. Often, when the motorist resorts to the use of this method, the radiator is washed both outside and from the inside.

An indicator and a sign that the radiator device needs washing and cleaning, the contaminated coolery fluid will serve. It is important to notice that the carrying procedure does not place and with the direct replacement of antifreeze. Nevertheless, should not be accepted with this operation. So, if the cooling fluid, when replacing, has one normal pre-color, then the radiator is not clogged.

In addition, there are also different types of anti-corrosion additives to the composition of modern cooling fluids, as a result of which they form a protective film inside the cooling system. The inner surface of the radiator is clogged for two reasons: driving engine oil and rust. If the motorist determined that the inner part of the radiator was contaminated, it should be washed through the use of special means. Before carrying out such operations, it is necessary to fully merge. If she has not changed for a long time, then it is necessary to replace it later.

After that, the system needs to pour distilled water, which will be deprived of all impurities, and add a tool that was previously selected to clean the cooling system. After that, you need to start the engine, and the system will be automatically washed within the deadline that is specified in the instructions for the washing medium. After that, it is necessary to drain the water and pour clean. The system will be revealed several times yet with clean water and after that it is possible to continue to inspect the device for contamination.

It is undesirable to resort to use when washing the cooling system of caustic sodaSince it remains a precipitate, which is able to destroy the inner surface of the device, and such a flushing can end with the purchase of a new radiator device. If even due to flushing, the motorist will notice overheating of the internal combustion engine, then the radiator device is simply failed, as a result of which it will be necessary to attribute it to the automotive workshop for a more detailed inspection.

It is also important to note that this kind of cleaning will be relevant for brass and copper radiators, as aluminum radiators that have plastic tanks are on a secondary use. The disassembly of this device is a fairly painstaking process, since the physical properties of aluminum do not allow to withstand the petals to fix tank beams more than once.

3. Features of the use of radiator cleaning agents

There would be no dangers in the contamination of the radiator if this device did not perform one of the main components of the successful operation of the engine - its cooling. This device is located constructively directly in the engine cooling system and performs the function of the heat exchanger, to which two circuits are approximate: the hot liquid for cooling falls into the radiator from the engine and the straight is directed back to the engine. For stable and normalized operation of the radiator device, it should be kept in purity, both outside and from the inside. If you figure it out, the procedure for cleaning the radiator is quite simple for everyone willing motorists. The only and unshakable condition for this procedure will comply with accuracy and care in fulfilling all operations.

In principle, there are no features when using a wide variety of means for cleaning the radiator. Nevertheless, it is important to know at least the basics that should be guided during the entire single procedure. Initially, for better and reliable cleaning of the radiator, you should choose a normal branded soft-chemical agent for cleaning it. Further, in accordance with the instruction that is attached, all these operations should be performed in order. It is best of all, of course, to clean the radiator in the removed state, where you can do everything thoroughly and "patch." Nevertheless, most liquids and such funds are used precisely with the active operation of this device and are used as tissures to antifreeze or other coolant.

The operational parameters of the auto depend not only on the state of it power aggregate 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 you perform forest cleaning The heat exchanger can be directly by car 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 flushing and installing the radiator, you need to get rid of air traffic jams in the 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. Anyone who is interested in creating a personal car radiator is obliged to know the fact that corrosion and scale are effectively removed by solutions with an acidic medium, and the 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.

Engine cooling radiator is designed to support operating temperature, does not allow the motor to overheat and basically copes with its task.

But during the operation of the car, the radiator is littered with mud and garbage, in this case the heat from the radiator in the environment is not fully given, the power unit overheats occurs. Cleaning car radiators is required as they are clogged, and if it does not produce it in time, the engine can fail.

Sorious heater cooling radiator can be clogged in the cabin, automatic transmission (if the car is installed automatic transmission), condenser or air conditioner evaporator. Floating RO Box automatic leads to overheating of the gearbox, and the stove scored by mud does not allow heat to pass into the cabin, and in the winter it becomes cold.

During the operation of the car, RO is littered from any garbage and dust flying from the road. Clogging is faster if the car drives country roads, on a strongly dyed area. Insects are stuffed from the route to the radiator, and the whole litter with time is crushed with dust into a solid mass.

In order to clean the outside, it is washed with water, cleaning the outer surface. But in place before the heat exchanger sometimes it is difficult to get, and therefore often radiators are removed in order to clean well. Still often the dirt is so firmly settled on the surface of the cooling element, which is not possible to consider it by conventional methods. In this case, special means for cleaning the car radiator come to the rescue.

At all times, RO was washed with running water, cleaning was performed on car wash under pressure. But it is necessary to use a strong water pressure neatly - you can damage the honeycombs, and then the radiator flows, will lose its tightness. If the salt settles the salt, it is necessary to remove it from the surface of the heat exchanger as soon as possible - the salt solution quickly corps aluminum, and the radiator quickly fails. Especially, the water does not wash out resistant sediments, and without chemistry for cleaning it is not necessary.

There are various cleaners of the outer surface of various radiators:

  • air conditioner;
  • cooling systems;
  • Automatic transmission;
  • engine oil system.

The market is well known for those cleaners as:

  • LIQUI MOLY;
  • Hado;
  • Lavr;
  • Verylube;

There are universal cleaners that can be cleaned not only the cooling radiator or air conditioner, but the engine itself. The price of the cleansing agent may be different, and the products of well-known brands are expensive. For example, a bottle of 250 ml of well-known motorists of the air conditioner cleaner Liqui Moly will cost about 1000 rubles. The universal cleansing agent for Kangaroo Profoam 2000 cars will cost much cheaper - 600 ml, the canopy costs approximately 250 rubles, however, the effect of it is worse than from Liqui Moly.

Recently, pairs are quite common to clean the radiator surfaces, steam, hot ferry radiators are cleaned effectively and quickly, while practically not used automotive chemistrywhich in other cases may be harmful to aluminum alloy.

Outer cleaning of the radiator cooling in DVS It is almost always done with the removal of the heat exchanger, but with a slight clogging, it is enough to blow with compressed air, and this can be done without removing the radiator. Consider on the example Ford Focus 2 how you can clean the car's radiator with your own hands on the spot without disconnecting the po:


If there is no compressor with compressed air and tool for flushing, then it will not work without removing radiators without removing, and on Ford Focus 2 remove them quite problematic. It is better to seek help in the car service, professionals will cope with this business without problems.

It does not always pollute the outside, it can also clog mud from the inside, and in this case the motor will also overheat. So that the heat exchanger is clogged with slag as much as possible, it is recommended at least once every two years to fully change the coolant, as Tosol (antifreeze) is flushed with the entire cooling system. Different cars are invented by motorists folk ways Rinsing RO - someone recommends flushing the cooling system with breast serum, citric acid or electrolyte, and someone advises rinse the Pepsi Radiator Koloy or even caustic. All these ways are dubious, it is likely that after such a wash will have to change the radiator.

The most reliable way is to clean the cooling system with ordinary clean water, flushing in the following way:

There are various auto chemicals on the market, with which the cooling system is washed effectively. But it should be noted that the funds are different, and not everyone benefit the engine and the car as a whole. It works very well here: a cheap remedy - a deplorable result. For flushing radiators, use products famous brands with good reputation, and on low price You should not buy.

The most famous manufacturers of sufficient quality auto chemicals are:

  • Hi-Gear;
  • LIQUI MOLY;
  • Lavr;
  • Pingo;

The tool is produced different in composition and appointment - some of them are poured as a additive to antifreeze for cleaning the system, others prevent science and rust formation. There are chemistry, with which the toxol leaks from the nozzles and the radiator is eliminated, but it needs to be used carefully, since the pipes and thin hoses of the cooling system can be clogged.

Signs of the clogged cooling radiator

There are signs for which you can understand what RO has been scored:

  • the cooling fan began to turn on more often, and not only at idle, but also on the go;
  • the engine is quickly heated, from expansion tank When heated, Tosol is thrown out;
  • the bottom of the radiator and the lower nozzle is cold, the upper hoses of the cooling system are hot;
  • in the cabin car badly warms the stove.

But all the signs testify not only about the scored RO, the cause of overheating can be:

  • burned block head gasket;
  • defective thermostat;
  • incorrectly adjusted ignition;
  • restaging the cooling system.

Even if the reason for the overheating of the engine is not detected, still cleaning the radiator will not be superfluous, especially if there are external signs of its clogging:

  • outside on RO, dirt is visible;
  • tosol in a turbid cooling system, with rust traces.

The condenser in the car is almost always installed in front of the main cooling radiator, so the whole dirt from the road first of all "gets". Sometimes the condenser is clogged so much that it is not possible to wash it and clean it by conventional means.

With a clogged condenser, the air conditioner does not only work well, but the engine is also overheated. What could be the connection between the cooling system and air conditioning? Everything is simple - the fulfillment of the air conditioner's radiator does not pass the air flow on the PO, and therefore the main radiator is not fully cooled. As a result, the engine itself is overheated.

Remove condense once again It is not necessary - it will have to refuel by freon after cleaning, so cleaning is usually produced in the car. Liqui Moly is considered to be the best tool in the market for cleaning air conditioners, but the whole problem is in the mud wash. Under a large pressure, the water cannot be supplied, the cells of the condensor will sound, and yet the output from the position is - you can use the Garden Sprayer with a volume of 5-9 liters.

We do as follows:

Fully laundering the air conditioner's radiator is unlikely to succeed, but for the normal functioning of such a cleaning system, and most importantly - the engine will stop overheating with the air conditioner turned on.

  1. Even if the cooling radiator behaves normally, it is recommended to rinse it at least once every two years.
  2. Before washing, it is necessary to warm up the engine, and rinse better with warm water - the mud will faster from the system.
  3. You can not wash or blow radiators under greater pressure - you can easily damage honeycombs.
  4. Experiment with various means for cleaning are not worth, experiments can lead to RO damage.
  5. If the cleaning from the inside does not help outside, you need to prepare for buying a new radiator - it is better to spend money on purchasing a new ro, than to repair the engine.

According to the regulations, the car washing the radiator should be carried out annually in the spring. However, depending on the number of heat exchangers used by the cooling liquids and operational features of the car, emergency cleaning of the heat exchanger is necessary. To do this, you should know signs of clogging, ways to clean and types of detergents suitable for this.

Construction of car radiators

The heat exchanger of the cooling system of the machine passes through itself antifreeze, with which the excess thermal energy is removed from the engine. The fluid should be cooled due to the high thermal conductivity of the radiator structural material (copper or aluminum alloy) and constant by blowing air, for which this node is made directly to the machine bumper.

On the other hand:

  • all dust and dirt falling precisely on the heat exchanger grille, cleaning the radiator may be damaged by a mechanical random stone;
  • when driving honeycombs, the thermal conductivity of the structural material falls;
  • from the inside the tubes are clogged with scale and contained in antifreeze materials, it is necessary to clean the radiator with a special fluid.

In modern cars, in addition to the engine, cooling fluids are circulated in the radiaries of the stove and air conditioning. Therefore, for each of these nodes, washing the car's radiator with their own hands, and different ways. The easiest is the outer wash with a high pressure apparatus.

Signs of decline in heat exchanger efficiency

Since antifreeze reduces the temperature inside the heat exchanger exclusively due to air cooling, There is a dependence of the effectiveness of its work on the time of year, or rather the ambient temperature of the air.

Planned flushing of the engine cooling radiator is because it is carried out in the spring, which allows you to get rid of impurities inside the system before the hottest summer season, when heat loads reach their peak.

Symptoms of a decrease in the efficiency of the heat exchanger for the driver are:

  • increased fan speed and its frequent switching on;
  • problems with stove and climatic equipment;
  • tableless antifreeze temperature sensor;
  • inertness of the system on the signals of the row;
  • interruptions in the work of the pump;
  • uneven heat exchanger heating (hot upper nozzles, cold lower part).

In any of these cases, the automotive radiator is washing as the most budget version of the problem. Outdoor washing The hundred is vital in the presence of any number of dirt, dust, herbs that scored midges.

ATTENTION: Installation from the inside or outside the grid of the radiator of the protective mesh screen by 90% solves the last problem.

Popular Cleansing Tools

In specialized stores, a means for high-quality flushing of the radiator is represented by a wide range. However, "Folk" methods and funds are often used to reduce repair budget. It should be remembered that not all of them are harmless to copper and aluminum, of which heat exchangers are made.

Folk

If budget cleaning is produced, the radiator is filled folk remedies:

  • three-axle carboxylic acid - flushing of the radiator from the inside with citric acid is effective for prophylaxis, but it is not possible to remove serious blockages, it is recommended to pour it for 3 days, then rinse the system with distilled water until it starts to merge clean fluid;
  • Fed is the basis of the same citric acid, but in smaller quantity;
  • serum - weakly concentrated lactic acid, is poured only after filtration through the gauze, after 50 km of the mileage merges in the hot state, washed with boiled water or distillate;
  • the caustic soda is caustic, only copper heat exchangers can be cleaned, pre-removed from the car, with disconnected pipes, is poured on ½ hours, washed with boiling water for 40 minutes, then frozen by air;
  • tools for cleaning the sewage - Washing of a car with a radiator is allowed only for copper heat exchangers, aluminum is extended by sodium hydroxide after 15 minutes, the radiator will have to be changed entirely;
  • saltic acid - a concentration of hydrochloric acid is allowed to 3% maximum and only for copper heat exchangers.

In principle, the car owner will help the table washing fluids For automobile units from different structural materials below:

ATTENTION: The appearance of a foam from the radiator indicates a caustic reaction with internal deposits, which is a normal effect for this cleaning method.

General principles when removing from narrow channels of third-party deposits are:

  • when we rinse the system from dirt, you need to be prepared for the fact that these sediments could partially block small cracks, pores and holes, can "flush" pump and separate areas of the radiator;
  • if the system, at least once, tap water was flooded, its acidity could be increased, which negatively affects the places of soldering by Tin, while even special additives in antifreeze are designed to protect tin.

Milk acid can not be compared in aggressiveness with caustic soda, however, this substance softens rust from the inside is better than all other products. The only problem is its absence on store shelves, because of what motorists have to make serum independently.

Special fluids

For external cleaning of the automotive radiator, special sprays in the canopy are considered the most effective. However, they are twice as expensive than similar products for the engine, and the composition is practically no different. Therefore, the engine is quite suitable for washing with a limited repair budget.

ATTENTION: Washing of a radiator car without removal by 30% is less effective in comparison with the cleaning of the heat exchanger, dismantled from the cooling system of the machine, and, among the same means.

  • Kuhler-Reiniger - Manufacturer Liqui Moly, aggressive alkalis / acids does not contain, is considered a universal drug for aluminum and copper heat exchangers;
  • Hi Gear - divorced in water, poured for 7 minutes, only in the warm season;
  • ABRO R Flush - is a corrosion inhibitor, poured for 10 minutes;
  • Pingo - budget German;
  • LAVR - in the composition there is a corrosion inhibitor.

Choosing a liquid for the internal cleaning of the heat exchanger, the factors should be taken into account:

  • alkaline tools cope exclusively with the organic;
  • acids dissolve inorganic products;
  • neutral liquid is more suitable for prevention;
  • two-component chemistry (acid + alkali) are outlined almost all compounds;
  • however, two different means should not be used at the same time, if you are not a car chemical manufacturer.

For example, the domestic laurel, removing the problem of deposition of scale and deposit deposits, further improves antifreeze resource by 30%. And the American High Gier carefully refers to rubber parts of the system, which allows not to remove the heat exchanger during cleaning.

How can I wash?

There are a number of "folk" drugs, which, in principle, cope with the removal of deposits within the heat exchanger, can harm:

  • when cleaning the Coca, the orthophosphoric acid contained in the drink will remove most chemical compounds, but carbon dioxide and dissolved sugar will result in problems;
  • Fairy does not cope with engine oil from the outside, sharply increases labor costs when pouring inside the heat exchanger, since 10 - 20 buckets of water will be required to remove all the foam formed;
  • White contains sodium hypochlorite, corrosive aluminum alloys, the corrosion rate increases with an increase in temperature;
  • fluid Calgon and similar substances (for example, Tiret) are removed from the water supply line, but is almost useless for car cooling systems;
  • a mixture of soda, citric acid and vinegar in proportion 2: 1: 1 is capable of corrosive rubber seals, therefore not recommended by specialists.

In the extreme case, you can pour Coca-Cola for 10 minutes maximum, then rinse with plenty of water. White is contained in some cleaners (for example, in Mr.), so first it is necessary to study the composition of the tool that will be used.

Washing technology

The general principles of cleaning the heat exchanger machine for the user are:

  • ideally, it is better to visit a hundred, having a special stand for washing radiators with adjustable temperature and head circulation treatment;
  • the heat exchanger must be cleaned from the inside and outside, it is best to dismantle it before that;
  • however, the old antifreeze will have to be replaced with a new coolant;
  • therefore, the service will cost half the cost of a new radiator, if not more.

For example, spare parts for VAZ are quite cheap, it is easier to replace the heat exchanger entirely or make a flushing in the garage. To reduce repair time, it is better to serve all the radiators (DVS, air conditioning and heater).

From the inside

Cleaning the cooling system without dismantling the heat exchanger is made by technology:

  • drain of antifreeze through the bottom stop;
  • washing with boiled or distilled water;
  • pouring detergent;
  • washing with water;
  • pour antifreeze and removal of air.

However, when using folk remedies, the liquid remains in the cooling system for several days. Only after that it merges for washing and filling the heat exchanger with antifreeze. When using some drugs, it is enough to start the engine for several minutes / hours.

It is much more efficient to clean the cooling system when the heat exchanger is removed. In this case, the radiator can be "shaken", tilt at different angles to merge from it, as much as possible sediment can be.

Outside

When processing the radiator, the other technology should be used:

  • ensuring access - if the washing of the automotive radiator is made with their own hands at the place, without dismantling it, should partly disassemble the bumper, the grid or remove them entirely;
  • foam application - spray spray from the heat exchanger on the manufacturer's instructions;
  • flushing - foam is removed together with soluble mud with a ferry radiator, the nozzle must be adjusted to the slit jet.

ATTENTION: water under pressure can damage the cells of the heat exchanger, so the jet should be located at a right angle to the plane of the radiator, beat into the space between the plates parallel to them.

Radiator air conditioner

Since the air conditioner heat exchanger is embedded in the DVS cooling radiator or is located next to it, there is no problems with cleaning the owner. The washing instruction is absolutely identical to the above technologies. Makes regular cleaning radiator more maintainable and increases its operational resource.

Radiator heater

In all heat exchangers, the car circulates the same liquid. Therefore, without removing the heat exchanger, its individual clearance is impossible physically:

  • the flushing mixture is poured into the general system;
  • rinsed it entirely;
  • fill antiprooms completely.

To rinse the heat exchanger of the cooling system of the stove in place individually, it is disconnected from the pipes of the general system and collect in the scheme:

  • both hoses from the heater radiator are stacked in a bucket;
  • capacity is filled with detergent;
  • the incision of one hose turns on the pump with power from the battery.

After that, the cleaner circulates in a small circle of heat exchanger - a bucket, like on the bottom photo.

After washing with distillate or boiled water, the heat exchanger is turned on into the general system, which is filled with the coolant for further operation.

Due to the small sizes of this node after removal, it can be washed in the bathroom, adjusting the temperature and water pressure, and, in both directions.

Thus, even without a special stand, the radiators of the air conditioner, the engine and the heater can be rinsed by folk remedies or special cleaners with their own forces. Enough to know what connections in detergent There should be no technology without removing and after dismantling the heat exchanger in all the details given in this manual.
