How to clean the car radiator inside without removing. Flushing of the radiator: Review of funds and effective methods. Faithful signs of impending washing

The performance of the car depends on very minor things. Due to the leaky rubber pipes, part of the antifreeze can find out of the cooling system, and unnoticed overheating will be wrapped with colossal repairs. But even with a fully serviceable technique, the car's engine will be waiting for very strange collisions. The radiator is clogged with mud and stops performing its functions.

Dirt and salt

Before you take for an expensive washing, it is better to make sure of its need to thoroughly. If the cooling fan often bursts under the hood, and this is no reason to look at the radiator with a flashlight. Pollution is visible to the naked eye. Between Sot, dried insects, needles, blades and winter salt were clogged. In the worst case, there is just a crust of a gray solid substance, impenetrable for air flows.

"There are two most optimal periods per year for a radiator washing procedure. This is April and July, "says technical expert Carfix Oleg Chirkov. In summer, cooling cells are clogged down by the poplar and sticky kidneys. Under the action of temperature, they are compacted and penetrate deep into the cells, where they sin in a dense mass together with dust. Air flows cannot break through such a pillow, and the cooling process of the motor is broken. But the saddest thing is when a winter dirt is superimposed on a fat poplar fluff with salt.

Usually takes several years before the new radiator is experiencing a deficit of heat transfer. In some southern cities with multiple dust, the contamination process is delayed by 7 years or more. In Moscow, with an abundance of winter salts and chemical reagents - a little less. 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.

Water is dangerous

The problem is that the radiator washing is a 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.

In general, the radiator washing at the modern "seven-year" is a complex technical process that has a pre-prescribed algorithm of actions. Machine must make a master of certified car services, familiar with technology and having tolerance.

Meanwhile, radiators are often clean by the owners independently in the garages. It concerns this mostly very old machines without complex electronics and with uncomplicated engine cooling systems. Antifreeze is pre-drained, disconnect rubber cuttings and pull out the radiator from the car. Then it is put on bricks, "Karcher" is taken, and the jet of water is shed dirt. But here it is necessary to be neat, since the high water pressure can damage the cells. Water in limited spaces repeatedly increases the initial pressure, on which the entire hydraulics is built. The cells are deformed and under the action of lambed dirt can be prolonged. In general, the pressure is better twisted to a minimum, and the radiator is pre-treated with chemical preparations for better peeling. Repeat the procedure is necessary depending on the degree of pollution.

The radiator on the car is needed so that the motor can not overheat during long work. At the same time, the radiator is clogged quite often, the dirt and garbage sticks on it, the warm air does not come out, but it remains to circulate inside under the hood, without giving the engine to cool. How to wash the removed engine cooling radiator? And how to understand that the problem is in it?

• Frequent launch of the cooling fan, even in real go, and not on idling.
• Too hot upper hoses in the cooling system at low bottom nozzle temperature.
• Slow survey heating with a stove.

Disregarding timely cleaning can bring to necessity overhaulTherefore, it is better to give five minutes to how to wash the engine cooling radiator, and get rid of a number of expensive problems later. In this case, it can be cleaned from the inside and outside.

How to wash the radiator outside

The easiest type of work is to wash off the dirt, swept sand and dust from the upper case. Often the radiator is covered with dried insects, especially if the car is often used in twilight - insects themselves fly to the headlights.

How to rinse the engine cooling radiator without removing:

• Merge the whole cooling fluid into a separate bottle (then the new one is poured). When plum, do not forget to disconnect all the nozzles, and not merge only from the main crane.
• Return nozzles back, spin everything again, and pour the cleaner through the main neck.
• Run the engine for half an hour maximum (you can 15 depend on the "indifference" of the liquid).
• Repeat the drain, revealing the faucet and nozzles.

When it became clear how to rinse the cooling radiator inside, the main question remains - the most effectively to do it. What to pour inside as a liquid for cleaning? You can take advantage of quite inexpensive options - to take gas production, citric acid or simply distilled water. Compare what is more effective.

Than rinse the engine cooling radiator inside

• Lemon acid. A solution with citric acid should be poured after complete cooling, because couples from the solution can be dangerous. On the solution citric acid It is necessary to "ride" by car at least a week - it will gently clean everything from the inside. After the drained solution of the treated solution, the part inside was washed before the toosol fill, otherwise the residues of the acid will spoil the substance.
• Coca Cola. Cola should be without bubbles, you can thoroughly stirrel to it or better - warm in a saucepan before filling inward. It launders the system faster, you can leave the engine to work 15 minutes (if the cleaning was carried out no more than a year ago) or travel to the "Coca-Kolov" cooling one day. After that, we drain, wash off the remnants and fill fresh antifreeze.
• Electrolyte. This is a mixture of water and rechargeable electrolyte Clear the radiator system is from about an active car ride.
• Distilled water. This is a weak purification method if the radiator is not polluted. Never use water from under the crane! It may have many salts that put down inside and will spoil the radiator. It makes sense to start flushing with water no more than twenty minutes.
• Vinegar. There are ten liters of water to dissolve 0.5 liters of 10% vinegar, after which the fluid should simult in the system all night (at least eight hours).
• Ready-made cleaning fluids. Based on an alkaline or acidic environment.

As you know, the main task of the automotive radiator is to maintain optimal operating temperature Engine. From how well the radiator performs its function, the operation of the motor directly depends. During operation, the radiator can be dirty both outside and from the inside, so motorists often have to face it with cleaning, and sometimes soldering if the radiator gave to flow.

It should be noted that both flushing and cleaning the automotive radiator are not difficult work, and its execution is quite forces for any car owner. If the case came to repair, for example, soldering of the radiator, before you independently do such work, you need to objectively assess your skills and opportunities, perhaps, better entrust the repair of the radiator to specialists?

Why do you need to clean and rinse the radiator?

Periodic outer cleaning of the radiator is necessarily needed. A contaminated radiator will not be able to provide a normal heat removal from the engine, as a result of which the engine will overheat. In turn, the engine overheating can end with a serious breakdown and expensive repair. But it was necessary to simply serve the radiator in a timely manner, that is, rinse and clean it.

Cleaning the car's radiator with their own hands

Everything would be nothing if the radiator did not perform the most important function - the engine cooling. The car radiator is structurally in the engine cooling system, performing the heat exchanger function in which two contours includes: Hot coolant from the engine getting into the radiator cools and goes back toward the engine. For stable work The radiator is necessary that it is clean both outside and inside, especially.

In principle, the cleaning of the radiator is not such a difficult, especially for the driver, who, when "wrench" or "screwdriver", does not fall into fainting. The only condition for cleaning the radiator with their own hands: accuracy and attentive execution of radiator cleaning procedures.

In fact, experts are recommended for the highest-quality external cleaning of the car's radiator to produce it on the removed (dismantled) radiator. After all, the place under the hood of a modern car is clogged until the stop, and the cleaning of the radiator is outside with water or compressed air under high pressure can damage the cells and brass tubes of the radiator. But it depends on your desire to know the device of the cooling system and the presence of time. After all, in order to dismantle the radiator, you have to remove the radiator grille.

Radiator cleaning agents

To rinse this important detail yourself, it is necessary to have elementary desire and time: the wash process is performed for a maximum of hours. Also does not prevent in advance to find out which gadgets you need for this. In the process of cleansing the radiator with their own hands, motorists typically use the following components and tools: effective cleaning agents:

- antifreeze;

Ordinary distilled water;

Special cleaning substance;

Any working gloves;

Bucket or other drainage tank;

Rubber tube;

Large basin with soapy water;

- waste seats;

Safety glasses;

Different rags;

Screwdrivers and wrenches.

On a note: distilled water can always be replaced by -37 ° C "non-freeza". Another exclusive is the cleaning of coca-cola, known in the people as a great launder of Russian toilets, or citric acid, which together with water fall asleep into the cooling system and drive on the engine, which worked for a while, that is, on an uncomfortable engine. So that the wash procedure has passed successfully, the professional motorist usually applies a more or less soft auto chemistry, the value of which is mainly depends on the harness of the manufacturer.

Outdoor cleaning of the radiator with their own hands

The traditional cooling system radiator is a design of tubular-plate or tubular-ribbon lattices. It is used for these purposes brass or aluminum, both metal is very gentle and soft. They are not completely resistant to mechanical damage. It is necessary to take into account these quality radiator when dismantling - installation and directly cleaning.

The outer cleaning of the radiator consists in purging the cell with compressed air or water pressure. ABOUT high pressure We have already spoken. The purge is made on both sides, with the maximum accuracy, in order to avoid damage to the cell. It is not recommended that the use of chemicals to the external cleaning of chemicals are not recommended, which include aggressive acid components.

Inner flushing of radiator

The first thing to pay attention to when pluming from the coolant radiator is at its condition. If the fluid is clean, the flushing will be just a preventive measure. If there is a rust and scale in the coolant fusion, then the cleaning of the radiator is carried out just in time.

For the internal cleaning of the radiator, we will install it in place. Pour distilled water with a cleaning agent, as a rule, it is anti-vakipin (it cannot be used with a coolant, only with water). Previously used caustic soda.

After the bay of water, we start the engine and let him work 15-20 minutes. After that, we drain the water with a cleaner and at least 5 times we make washing the radiator with a clean distilled water. Fill the cooling fluid into the system. Without closing the radiator cover, we turn the engine to come out of the cooling system. Everything. You are ready to move. We will not be reminded that modern high-quality antifreeze in their composition lubricating and anti-corrosion substances, which prevents rust inside the radiator. But, prevention is a holy case. Good luck to you, lovers of their car.

If the radiator is required to repair?

During the prophylactic maintenance of the radiator, it is sometimes found that in some places of the coolant of the radiator "cry", that is, there is a crack, and well, if this crack is small. What can be done in this case?

1. There are "folk" ways to repair the radiator, for example, by falling asleep inside the mustard powder or breaking the raw egg there. In principle, if there is no other exit and the radiator gave to flow on the road, it can be resorted to such methods in many cases.

2. But today, auto chemical manufacturers were able to offer motorists more modern means for repairing small cracks in the radiator, which is not difficult to find on sale, it can be powder sealants or special fluid To restore the radiator.

3. Another indispensable tool can be the so-called "cold welding". Often, after repair, the radiator is not yet one year.

4. As for the fundamental repair of the radiator, including its soldering, then it is decided to decide for this work independently or to seek help from specialists depends on your skills you have equipment and materials.

And therefore requires timely cleaning. It is not as difficult as it may seem at first glance and much can be made with your own hands. For example, rinse the engine cooling radiator without removing it.

How it is arranged and for what the engine cooling radiator is needed

The radiator in the car saw everyone. Roughly speaking, it is such a grid metal screen installed in front of the engine. It consists of a plurality of tubes (or rather, from one convoluted very long tube) and thin like foil, metal plates. A hot coolant flows through the tube, which gives heat to these plates, and also cools down by blowing the radiator with an air flow. That is, the coolant circulating through the engine cooling system takes heat from it, and then falls into the radiator where the heat gives. The radiator has a neck where coolant (, toosol or water is poured.

Of course, inside the radiator is assembled by the largest number of different garbage generated during the circulation of antifreeze or water. And besides, the radiator is polluted and outside, which worsens heat exchange processes. Therefore, from time to time it is required to clean the engine cooling radiator.

When you need to wash the radiator

Of course, before you climb into the hidden places of your car, you need to make sure that there is a need. To identify it will be pretty simple diagnosiswhich you can spend yourself. So, first of all, the driver's attention should attract frequent inclusions when there are no good reasons for this, such as heat or engine operation under heavy load. This signals that the cooling of the fluid in the radiator is worse. Perhaps the tubes and antifreeze or water are badly circulating.

Also, when the moment of replacing the coolant is occurring, merging it from the system, you must pay attention to extraneous particles, torture, changing the color. If all this takes place, then, most likely, the radiator is contaminated from the inside.

But even if it is not so, cleaning the engine cooling radiator for prophylaxis does not hurt. By the way, the "honeycomb" scored, that is, the spaces between the plates, as well as deposits on the inner surface are the most common causes of the disorders of the radiator.

How and what to clean the radiator

As they say, ideally, for a good cleaning, the radiator needs to be removed. So it turns out to process it from all sides. However, since a long time to mess around with the engine from motorists, few people want or may often arise about how to rinse the engine cooling radiator without removing it.

Make it is not difficult. Outside, remove dirt can be removed using Kerker or compressed air from the compressor. This technique today is in many garages, not to mention the car service. Efficiency will not be 100%, but, nevertheless, such pollution, as the dust embraced in the slit, fastened insects and the like will be deleted. If you have the opportunity to remove the grille and open good access to the radiator, then it will be possible to wash it with a brush (with plastic or genuine bristle medium hardness) and gasoline. This will help remove such pollution, such as, for example, the nanish tar. After that, you can proceed to the guidance of order inside.

At this stage, the cleansing liquid is needed, which is poured into the radiator and allow you to work the engine within a few minutes. Here option is possible: apply folk remedies or buy special meansintended to rinse the engine cooling radiator inside. The most common and most ineffective folk remedy for these purposes is water. Maximum, which can be achieved with it, it is to wash off the remains of one coolant before the fill of the other. But at the same time, the procedure will have to be carried out several times.

It is also much more effective and also very affordable among drivers, so to speak, the "old hardening" is considered dairy serum. It is poured instead of coolant and pass several tens of kilometers, after which they drain. The system is then washed with clean water. It is believed that this way the radiator is well cleaned from the inside.

Another easily accessible liquid is Coca-Cola or Pepsi Cola. The fact that these drinks can not only drink chips, but also to shoot rust, it has long been known. The cola composed into the cooling system is able to remove scale and every fall. To do this, the engine must work for fifteen-twenty minutes.

Approximately used electrolyte for batteries. However, given the fact that it is strong acid, they are resorted to such measures only as a last resort. By the way, about acids. You can use citric acid solution (100 grams per 10 liters of water). Well, as for special automotive chemistry, it is sold in a wide range of selling in specialized stores. It is not worth saving here, since cheap fakes may not so much to clean the cooling system, how much seriously pull it away. The qualitative special funds with their task copes very well.

How to wash the radiator from the inside

Before washing the engine cooling radiator, from it (as, however, and from the entire system) you need to remove the existing coolant liquid. Therefore, a suitable container will be required and, of course, new antifreezeIf it will be poured into the system it is he, and not water.

The fluid from the cooling system on all vehicles through special cranes is merged. In addition, it is also worth disconnecting the nozzle from the radiator to delete it completely.

After that, everything is connected back, the crants are tightened and the selected cleaner is poured through the mouth of the radiator. In most cases, it is necessary to give the engine to work from 15 to 30 minutes, after which itching the cleaner just as antifreeze was merged.

• during work, it is recommended to use protective gloves, resistant to chemical influences, as cooling and flushing fluids are rather aggressive and extremely poisonous.
• before merging the coolant, it is better to give the engine a little to work so that it proceeds through the system. It is necessary to merge when the motor will cool.
• rinse the engine cooling radiator is also important, since heat exchange will be worse on the contaminated surface.

  When after cleaning, antifreeze or water for cooling will be filled again, you must not forget to remove air traffic jams from the system.

• The better than the coolant, the less the radiator is polluted inside. In addition, it affects the cleanliness how much the driver is using antifreeze.

So, as can be seen, the procedure for cleaning the radiator is not at all complicated. At the same time, it is very important for good engine performance. It is recommended to make cleaning regularly and better combining with a coolant replacement in the system.

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 cooling fluid used ordinary water, insofar as 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 drain all 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 of a chemical reaction from the radiator pipes, white foam may appear. 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 remedies 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.
