The correct operation of the vehicle cooling system determines the quality of the vehicle's engine. The use of an optimally selected antifreeze eliminates the possibility of engine overheating. Over time, the channels of the system begin to clog. As a result, the operation of the internal combustion engine may be disrupted. How to flush the cooling system (CO) and what methods can be used for this, learn from this article.

[Hide]

Why and when do you need to flush the vehicle cooling system?

Flushing the cooling iCE systems must be performed in case of clogging. CO includes a number of components that must work properly and interact with each other. This will allow the antifreeze to cool the hottest elements. power unit... The most vulnerable component of the cooling system is the pipes. Over time, they become clogged and destroyed as a result of exposure to high loads.

In the process of using the machine in engine compartment sand, rubble, stones from the road, and insects can enter, which leads to the formation of dirt on the unit. As a result, some of the contaminants appear in CO and mix with the consumable. This contributes to the formation of scale on the metal components of the system, which eventually flake off and get into the pipes. As a result, the lines begin to clog, and this contributes to a decrease in the efficiency of the CO, in some cases, its complete failure is possible.

Proper flushing will effectively remove contaminants from the lines. You can find out about the need for cleaning by the appearance of the antifreeze indicator on the control panel. If the light is on, this may indicate not only the absence of consumables, but also the presence of problems in the operation of the CO. Experts recommend flushing the flushing process at least every two years.

Determination of the degree of clogging

There are several ways to determine the degree of CO contamination:

1. Engine inspection. Its overheating can be associated with various reasons, but the lack of cooling of the power unit is one of the main ones. If the motor constantly overheats, you need to run a cooling system diagnosis.
2. Check expansion tank... The degree of clogging can be determined by the presence of sediment in the tank. But for this, the container will have to be dismantled. It is unlikely that it will be possible to determine the presence of deposits on the reservoir installed under the hood. You can try shining a flashlight on the container. If a layer of deposits is visible at the bottom, then it is time to flush with CO.
3. Monitoring the state of the coolant. The presence of rust and traces of scale in the coolant indicates the need to replace the refrigerant and purge CO.
4. Inspection of hoses. Clogged connections can be identified by disconnecting one of the hoses. Be careful as refrigerant will start to escape from the line when disconnected. If you see a blockage inside the tube preventing the consumable from flowing through the system correctly, then flush it.

Flushing methods

To clean the cooling system, you can use the services of specialists at the workshop. But there is nothing difficult in this procedure, so we suggest you learn how to complete such a task yourself. Effective flushing can be carried out using special fluids or with improvised means. Below we will tell you about how you can flush CO at home.

Using water

Water - let not best remedy, but the most affordable option for car owners. But for washing, you should not use an ordinary liquid, but a distillate. The fact is that the composition of tap water may contain molecules and substances that aggressively affect the rubber elements of CO. If some of the liquid settles in the system, it will destroy the rubber components.

The distillate cleaning process is relevant for all cars, be it Daewoo Sense or Mercedes, and it is performed as follows:

1. We cool the engine. The procedure is performed on a cold engine, so wait for the internal combustion engine to cool down.
2. We remove the used material. To get rid of the old antifreeze, you need to unscrew the plug and wait until the consumable is completely out of the system. Don't forget under drain hole install a container to collect the drained liquid.
3. We fill it with water. We twist the plug and pour distilled water into the CO using an expansion tank. The volume of water must correspond to the volume of the coolant drained from the system.
4. Flushing process. We start the engine, let it run for a while. You can even travel a little. It is desirable that the engine run for about 15-25 minutes.
5. We drain the water. If it is too dirty and there are traces of deposits and scale in it, then it is advisable to repeat the cleaning procedure. When clean water comes out of the system, it will become clear that the result has been achieved. You can now fill in new antifreeze.

Advantages and disadvantages

The main advantage of this method is its availability and low cost. Finding a distillate is not a problem. The disadvantage of this method is that its implementation is more relevant for preventive purposes, when the level of contamination is low.

Artem Petrov provided detailed instructions for CO purification.

Use of acids

CO can be washed with citric or phosphoric acid solution. This option is especially relevant for those car owners who want to clean the system from sealant or oil residues. The cleaning procedure is carried out in the same way as with water.

To carry out the task of removing contamination with kilotes, the following nuances must be taken into account:

1. Proportions. To make a solution for cleaning a highly contaminated system, you will need 1 kg of acid and 10 liters of water. For moderate contamination, the volume of acid can be reduced to 800 grams per 10 liters of liquid.

Technical features. The procedure is carried out in the same way as for rinsing with water. After pouring the solution into CO, you need to drive a car for some time. Let the motor run at both idle and load conditions. After driving, stop the engine and leave the car with the acid filled with CO for 45 minutes.

Thorough rinsing. After draining the solution, flush with CO with regular distillate. To do this, repeat the cleaning procedure 3-4 times.

Advantages and disadvantages

For flushing with this method, you will have to spend money. In addition to 20 liters of distilled water, you will need to buy citric acid. The average cost of one kilogram is $ 1-2. Note: if you overdo it with proportions, then the acid can corrode the pipes and gaskets.

Using vinegar

With your own hands, you can clean the system using vinegar. It is important to observe the proportions here: half a liter of vinegar is added to 10 liters of distillate. Cleaning consists in pouring the solution into CO, further warming up the power unit to 100 degrees and stopping it. After that, the machine is left for about 8-10 hours. When draining the liquid, pay attention to its condition. If there are traces of rust and scale, as well as dirt in it, then the procedure is repeated. When the cleaning is completed, the unit is flushed with distillate.

The CO flushing procedure with vinegar is shown in the video filmed by the "Little bit of everything" channel.

Advantages and disadvantages

The advantage is the low cost. Vinegar is cheap, so you don't have to spend a lot on this flush. The main disadvantage is that this process takes a long time. If the engine contamination is serious, it will take several days to clean.

Caustic soda

The use of this option is relevant for cleaning the radiator device and heater. The use of soda is allowed only on parts made of brass or copper. If your car is equipped with an aluminum radiator, then the use of caustic is not allowed. This product can also be used to clean the jacket of the cooling system. When performing this method, observe the proportions: pour about 50 grams of soda into one liter of distillate. The radiator must be dismantled before cleaning.

Advantages and disadvantages

The positive properties include its significant cleansing effect. Caustic soda is a powerful substance that almost no pollution can resist. The price is quite low, which is also an advantage. The main disadvantage is that the substance is unsafe. When working with it, precautions must be taken throughout the cleaning procedure.

Milk serum

This tool is characterized by the presence of elements in its composition, the chemical characteristics of which allow dissolving deposits and scale, while not affecting negatively the rubberized components of the cooling system. Before pouring the whey into CO, strain it through a sieve. After the gulf of serum, you should drive about one thousand kilometers on it. After draining the fluid, the system must be flushed with distilled water and filled with antifreeze that meets the engine specifications.

The Dachny Master na Vse Ruki channel showed the result of washing the OS with serum.

Advantages and disadvantages

The main advantage of this method is its efficiency. The serum also cleans the lines of the cooling system and the radiator well, as well as specialized products. The disadvantage is that the cleaning process is very time consuming. If you urgently need to flush the system, then this method will not work. Also, its implementation is impossible in the cold season, since the serum will quickly freeze in the cold, and this can lead to more serious consequences. In addition, after the flood, you will need to check its condition from time to time and be sure to monitor the operating temperature of the internal combustion engine.

Rinsing with Coca-Cola

As the reviews show, the use of Coca Cola is considered one of the effective methods pollution control. The product contains orthophosphoric acidwhich quickly removes rust and scale. Be careful, as there is sugar in Kolya, and it clogs the system lines and the radiator device. The flushing process is carried out in the same way as with ordinary water. After using the drink, CO is cleaned again with distillate.

Advantages and disadvantages

The virtue lies in efficiency. But due to the acid content in the composition of the drink, there is a possibility of destruction of rubber components and CO pipes. Coca-Cola is a liquid product with gases. As a result of heating the motor to working temperature the gases will expand, and this can have a devastating effect on the operation of the motor. Before pouring the drink into the cooling system, we recommend unscrewing the cap and waiting for a few hours until the gases come out. Another disadvantage is the high cost.

Chemicals

For cleaning, you can use special flushing agents, for example, Hi-Gear or Liqui Moly. The range of such products is large. Mild flushing chemicals do not negatively affect the condition of the radiator and CO hoses, and it allows you to clean the system quickly enough.

There are several types of chemicals:

1. Neutral. There are no aggressive molecules in the composition of substances. Such washes are not as effective as compared to other consumables; their use is more important for prevention.
2. Alkaline. Reviews show that such products are good at removing organic pollution. You won't be able to find them undiluted on the market.
3. Acidic. They are very aggressive towards the constituent components of the cooling system. Their operation is relevant for removing scale, as well as inorganic contamination.
4. Two-component. These products contain alkali and acid. These products are consistently poured into CO and make it possible to effectively clean it from any type of dirt.

Advantages and disadvantages

The advantages include a huge selection of funds and their effectiveness. In practice, chemistry is always better at cleaning the cooling system than other fluids. Moreover, its application will allow you to quickly achieve results. The disadvantages include high cost funds.

In order to avoid problems in the work of CO, consider the following nuances:

1. Do not use tap water for flushing.
2. To create a solution, only the use of a distillate is allowed.
3. Pour only high-quality consumables into the cooling system, do not skimp on buying antifreeze.
4. Perform a visual inspection of the refrigerant periodically for deposits, dirt and scale, and traces of rust.
5. Change the fluid in the system at least every 3 years or after 40-80 thousand kilometers.
6. When replacing consumables, perform CO cleaning.

How to flush a car engine cooling system?

The engine cooling system needs regular cleaning to ensure optimum temperature regime engine operation.

Symptoms that the cooling system (SOD) needs cleaning are as follows:

• overheating of the engine;
• the formation of internal and external leaks of antifreeze or antifreeze;
• the stove does not heat well;
• the circulation of the coolant is disturbed.

In the SOD, scale settles over time, which clogs the radiator tubes. ... So, a sealant can get into the antifreeze, with the help of which small cracks and holes are sealed.

In addition, oil can also get into the SOD.

The very same coolant also needs regular replacement, especially antifreeze. Due to the fact that while the engine is running, it constantly heats up and cools down, a change in the chemical composition occurs - the salts precipitate, the water base leads to gradual corrosion of the pipes and metal elements of both the radiator itself and the engine.

Many drivers believe that it is enough from time to time to simply drain the old fluid and refill the new one. If you drain the antifreeze, you saw that it is far from transparent, but brown from all these contaminants.

Ideally, washing the SOD should be carried out until completely clean water is poured out of it.

It is also important to carry out external cleaning of the radiator, since it also does not look the best way, a lot of dirt, dust, insects and so on settle on it. The correct decision would be, of course, to go to the service station. True, there may be a long queue at the service, and you will have to pay two thousand rubles for this service, or even more, because in some models, in order to get to the radiator, you have to completely disassemble the entire front end.

How to clean the radiator yourself?

In principle, this is not the most difficult procedure. You can clean the radiator using auto chemicals or improvised means. Rinsing is carried out after draining the antifreeze. Let's see what the modern market offers.

This tool allows you to very effectively, and most importantly quickly, to clean the SOD. It contains neutral substances that do not pose a threat to rubber elements - oil seals and tubes (subject to the instructions), - phosphates and functional additives.

Application:

• unscrew the tank or radiator cap, open the interior heater tap
• warm up the engine to 60 degrees, let it run for no more than five minutes;
• turn off the engine and drain the old antifreeze;
• mix the contents of the jar with distilled or boiled water (the proportions are indicated in the instructions);
• pour all this into the system and let the engine run for 7 minutes;
• drain all this liquid;
• repeat rinsing with plain water several times until all dirt is washed out.

The tool is really effective, it cleans the system very well. You need to follow the instructions, otherwise the effect will be subtle.

Other auto chemical products include:

• Mannol Radiator Flush;
• Liqui Moly Kuhlerreiniger;
• Jet 100 Xado;
• ABRO Radiator Flush.

When using this or that remedy, be sure to read and follow all the requirements, because there are many complaints that, they say, I bought an expensive flush, but it did not help. Although, as it turned out later, the person did not read the instructions at all, or bought a fake.

Also very good remedy - .

Flushing is carried out in the same way as above:

• drain the old antifreeze;
• pour LAVR into the tank, then add warm water to the MIN mark;
• let the engine run for 30-40 minutes;
• drain the product and rinse it several times with distilled water;
• pour in new antifreeze.

It helps very well to clean all the radiator tubes and the entire system. However, citric acid effectively fights only rust, while it is unlikely to help get rid of scale. If in the drained antifreeze you see not only small particles of rust, but also pieces of scale, then it is better to resort to two-component compositions like Hi-Gear.

(function (w, d, n, s, t) (w [n] \u003d w [n] ||; w [n] .push (function () (Ya.Context.AdvManager.render ((blockId: "RA -136785-3 ", renderTo:" yandex_rtb_R-A-136785-3 ", async: true));)); t \u003d d.getElementsByTagName (" script "); s \u003d d.createElement (" script "); s .type \u003d "text / javascript"; s.src \u003d "//an.yandex.ru/system/context.js"; s.async \u003d true; t.parentNode.insertBefore (s, t);)) (this , this.document, "yandexContextAsyncCallbacks");

Buy bags of acid and prepare a solution in a ratio of 1 to 10 - 100 grams of acid per liter of water.

The cleaning itself is carried out in almost the same way as described above, but with minor exceptions:

• drain the antifreeze, pour in the prepared solution;
• give a load to the engine - you can leave it to idle or medium speed, or drive somewhere, the engine should work no more than 40 minutes;
• drain all the liquid and continue flushing with plain distilled water until you drain the clean water.

Vinegar essence can also be used instead of citric acid.

Coca Cola and Pepsi Cola

This sweet soda not only leads to obesity and ulcers if drunk without measure, but it can be used very well to clean rust, here it can compete with Vedeshka.

Flushing is carried out in the same way, but it is not advisable to give a prolonged load on the engine - let it rotate for no longer than 5 minutes.

Be sure to thoroughly flush the entire system afterwards, because Coca-Cola contains sugar.

These drinks contain orthophosphoric acid, which fights rust well, and can remove scale, if there is not much of it. But getting sugar into the engine can be fraught with some problems. Therefore, if you have internal leaks of antifreeze, an old engine, then it is better not to get carried away with such cleaning methods..

Milk whey will attack both rust and limescale. If there is a lot of scale, then the lactic acids in the whey will simply soften it.

The principle is very simple:

• drain the antifreeze;
• pour in the serum previously filtered through cheesecloth;
• drive a car for a day or two;
• drain the serum and flush the system several times with distilled water.

The method really helps. This is the most affordable tool in the village, tractor drivers clean the radiators of their agricultural machinery this way. You can also use whey powder, which is sold in powder form.

What else do you need to know about flushing the radiator?

You don't need to get carried away with various folk remedies such as Coca-Cola or vinegar (this does not apply to whey).

The photo shows the radiator tubes before and after cleaning.

Do not forget also that the use of aggressive chemical compounds can lead not only to the formation of cracks in the rubber elements, but also in the radiator itself. Therefore, flush with licensed products, and use antifreeze recommended by the manufacturer as a coolant.

Well, do not forget about external flushing and purging of the radiator. By the way, the radiator can be protected from external contamination using a special mesh. And in winter, the radiator can be insulated so that the engine does not freeze and starts up easier in the morning.

Before we move on to a direct description of certain means, I would like to remind you how important it is to regularly flush the car's cooling system. The fact is that, depending on the coolant used, rust, oil deposits, antifreeze decomposition products, and scale accumulate on the walls of the pipes that make up the radiator. All this leads to difficulty in the circulation of coolant and a decrease in heat transfer. And this always has a bad effect on the characteristics of the engine and increases the wear of its individual parts with the risk of their premature failure.

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

On some machines on dashboard there is a light bulb with a radiator image, the glow of which may indicate not only a decrease in the level of antifreeze, but also that it is time to change it. This can also serve as a signal that it is time to clean the cooling system. There are also a number of indirect signs of the onset of the need for such cleaning:

Radiator icon indicating a problem with the cooling system

• frequent engine overheating;
• pump problems;
• slowing down the reaction to rheostat signals (inertia);
• high temperature readings from the corresponding sensor;
• problems in the operation of the "stove";
• the fan always runs at high speed.

If the motor gets very hot, then it's time to select a means to flush the cooling system, and choose the time and opportunities for this.

HOW TO FLUSH THE ENGINE COOLING SYSTEM

The process of flushing the cooling system is quite simple, and it consists of the following stages: The car engine warms up a little, after which it turns off and you need to wait a while until it cools down a little; Next, the plug is unscrewed, the old coolant is drained from the motor. Attention: Do not drain the coolant on a hot engine - this is fraught with burns and spray antifreeze under pressure; After that, you need to fill in the agent for cleaning the cooling system. Some of them need to be diluted with distilled water. If you are using citric acid or Coca-Cola for flushing, specific recommendations for using these fluids for flushing the engine will be given below.

In the case where specialized products are used, you must follow the instructions on the package; Then, for some time, it is necessary to let the engine work with a filled with a cleaning agent for the cooling system. The time recommendation depends on the type of fluid used; After flushing, the liquid is drained and clean water is poured into the cooling system to remove any residual detergent. The procedure for draining and filling water may need to be repeated several times; The last step new coolant is poured into the cooling system. Attention: it is better to choose the same antifreeze that was filled in the cooling system before flushing. Thorough flushing of the cooling system is necessary to remove the formed deposits, dirt, corrosive elements and harmful impurities that can lead to a violation of the stability of the system. We strongly recommend that you fill in new antifreeze after flushing the cooling system, because in the old fluid, even if the car has not traveled so many kilometers, there are dirt particles.

How to flush the engine cooling system at home?

You can flush the engine cooling system with the following fluids:

Distilled water;
Acidified water;
Special means for flushing the engine cooling system.
The choice of cleaning agent depends on the condition of the vehicle.

You need to flush the engine cooling system either outdoors in the summer or in a warm box in winter. First, drain the old antifreeze from the system - this process is described in great detail in the instructions for replacing the coolant. In short, the algorithm of actions is as follows:

If the motor is hot, it should be allowed to cool down.
Place the machine on a level surface.
Gloves are best to protect your hands from hot engine and cooling system components.
Open and secure the hood.
Place a container under the radiator to collect the old coolant.
Turning out drain plugs, drain the antifreeze in turn from the engine and radiator.
By the type of drained liquid, conclusions can be drawn about the state of the cooling system as a whole. The drained antifreeze may contain various particles (scale, rust, etc.).

Chemistry for flushing the engine cooling system

LAVR tool for cleaning the cooling system The main thing when flushing the cooling system is to observe safety measures and clear instructions. If we compare "folk" means with special factory formulations, then, of course, the latter are better. What flushes for the cooling system are on the market? Various. From very cheap to expensive, from unknown to brands with a name. In principle, there are no frankly terrible compositions among them, unless it is liquid from an underground production. To make it clear what to take, we denote several best washes engine cooling systems. Flushing the cooling system with Liqui Moly, like other brand products, has proven itself well. It is usually sold as a concentrate that must be diluted with water (three hundred grams per three liters) or added to old antifreeze.

Run through the system for ten to thirty minutes, then drain, rinse with distilled. Of the whole class of seven-minute washes, the Hi Gear cooling system flush can be distinguished. It gently cleans and even softens the rubber parts of the system. It is poured for seven minutes, diluted with water, the dosage of which depends on the volume that a particular cooling system holds (there are seven-liter and sixteen-liter engine cooling systems). Flushing the cooling system with Lavr offers different formulations: for different levels of pollution, with different additives, different duration of action, agents for flushing the radiator of the engine cooling system. Each tool is accompanied by an instruction, which describes in detail how to proceed.

Folk remedies for flushing the cooling system

As we indicated above, there are two types of flushing agents - folk and special. Let's start with the first ones, as they are cheaper and more proven.

Lemon acid

Using citric acid to clean the cooling system

The most common citric acid, diluted in water, is able to clean the radiator pipes from rust and dirt. It is especially effective if ordinary water is used as a coolant, since acidic compounds are effective against rust, and alkaline ones are effective against scale... Remember, however, that citric acid solution will not remove significant contamination.

The composition of the solution is as follows - dissolve 20-40 grams of the substance 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). It is considered ideal when adding acid to distilled water the pH is around 3.

The cleaning procedure itself is simple. It is necessary to drain all the old liquid and fill in a new solution. Next, you need to warm up the engine to operating temperature and leave it for a few hours (or better at night). Next, drain the solution from the system and look at its condition. If it is very dirty, then the procedure must be repeated 1-2 more times until the liquid is sufficiently clean. After that, be sure to flush the system with water. Next, fill in the product that you plan to use as a coolant.

Acetic acid

Using acetic acid to clean the cooling system

The action of this solution is similar to that described above. Acetic acid solution is great for flushing rust from the cooling system. The proportions of the solution are as follows - half a liter of vinegar per bucket of water (10 liters). The cleaning procedure is the same - we drain the old liquid, fill in a new one and warm up the car to operating temperatures. Next, you need to leave the car with the engine running for 30-40 minutes so that chemical cleaning takes place in the radiator. Next, you need to drain the cleaning liquid and look at its condition. Repeat the procedure until the liquid is clear. Next, you need to flush the system with boiled or distilled water, and then fill in the coolant that you plan to use on an ongoing basis.

Fanta

Using Fanta to clean the cooling system

Similar to the previous point. However, there is an important difference here. The fact is that, unlike Coca-Cola, where phosphoric acid is used, Fante uses lemon acidwhich has less cleansing effect. Therefore, some car owners pour it instead of antifreeze to clean the cooling system.

As for the time during which you need to drive like this, it all depends on the degree of contamination of the system. In particular, if it is not very dirty, and cleaning is done more for prophylaxis, then it is enough to let the engine run for 30-40 minutes at idle. If you want to wash out old dirt well, then you can ride like this for 1-2 days, then pour distillate into the system, ride some more, drain it and look at its condition. If the distillate is dirty, repeat the procedure until the system is cleaned. Finally, do not forget to rinse it thoroughly with water and add new antifreeze.

Please note that if there are small holes or cracks in the stove piping, but the dirt has “tightened” them, then these holes may open during flushing and a leak will form. Therefore, after flushing, revise the system piping.

Lactic acid or whey

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

A more affordable alternative to lactic acid is whey. It has similar properties for cleaning the radiator and other elements of the cooling system. The algorithm for using serum is as follows:

Using milk whey

• prepare about 10 liters of whey in advance (preferably at home, not from the store);
• strain the entire purchased volume 2-3 times through cheesecloth in order to filter out large pieces of fat;
• first drain the coolant present from the radiator, and pour serum into its place;
• drive 50-60 kilometers with her;
• it is necessary to drain the serum while it is hot so that the dirt does not have time to stick to the walls of the tubes again ( be careful when doing this!);
• let the engine cool down;
• pour boiled water into the radiator;
• start the engine, let it warm up (about 15-20 minutes); drain the water;
• let the engine cool down;
• pour in antifreeze that you plan to use on an ongoing basis;
• bleed air from the system, if necessary add more coolant.

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

Caustic soda

This substance is popularly called differently - sodium hydroxide, "caustic alkali", "caustic soda", "caustic" and so on.

The substance can only be used to clean copper radiators (including the heater radiator). Do not clean aluminum surfaces with baking soda.

In accordance with official instructions the manufacturer of copper radiators must act according to the following algorithm:

Caustic soda

• remove the radiator from the car;
• rinse its insides with plain water and blow it with compressed air (not exceeding a pressure of 1 kgf / cm2) until clean water flows out of the radiator;
• prepare about 1 liter of 10% caustic soda solution;
• heat the composition to at least + 90 ° С;
• pour the prepared composition into the radiator;
• let it brew for 30 minutes;
• drain the solution;
• rinse the inside of the radiator for 40 minutes hot water and blow through with hot air alternately (while the pressure should not exceed 1 kgf / cm2) in the opposite direction of the pump movement.

Remember that caustic soda burns and eats away at living tissue. Therefore, it is necessary to work outdoors with gloves and a respirator.

As a result chemical reaction white foam may appear from the radiator pipes. If this happens, do not be alarmed, this is normal. The tightness of the cooling system after cleaning must be carried out on a cold engine, since hot water evaporates quickly, and it will be problematic to find the expected leak.

Flushing the engine cooling system with distilled water

We would like to note right away that this is the most inexpensive method of flushing the engine cooling system, but at the same time it is the least effective. In terms of time and effort, washing with distilled water is also not the first place. However, in some cases, this method will be fully justified.

Naturally, plain tap water cannot be used to flush the engine cooling system. Only distilled water should be used or, at worst, boiled for at least 20 minutes (it contains a minimum of salts).

Flushing the cooling system is simple:

Pour distilled water into the radiator.
Start the car and let it run idle for about 15-20 minutes.
Stop the engine and drain the cooling system.
This procedure must be repeated several times until the water is clear. This method is suitable only if the car is relatively new, and no obvious contamination is visible in the drained antifreeze.

Question, how to flush the engine cooling system, interested in car owners who are faced with problems. There are both folk remedies for cleaning (citric acid, milk whey, Coca-Cola and others) and modern technological formulations. Let us dwell on those and other options in more detail.

Cooling system cleaners from oil, rust and deposits

How often to flush

Before we move on to the direct description of certain means, I would like to remind you how important it is to regularly flush the car's cooling system. The fact is that, depending on the coolant used, rust, oil deposits, antifreeze decomposition products, as well as scale accumulate on the walls of the tubes of which it is composed. All this leads to difficulty in the circulation of coolant and a decrease in heat transfer. And this always has a bad effect on 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 system can be flushed both internally and externally (external cleaning involves flushing the radiator from the outside of the particles of dirt, dust, insects on its surface). It is recommended to do internal flushing of the cooling system at least once a year... It is best to do this in the spring, when there is no longer frost, and a hot summer is ahead.

On some cars on the dashboard there is a light bulb with a radiator, the glow of which may indicate not only a decrease in the level, but also that it is time to change it. This can also serve as a signal that it is time to clean the cooling system. There are also a number of indirect signs of the onset of the need for such cleaning:

Radiator icon indicating a problem with the cooling system

• frequent engine overheating;
• pump problems;
• slowing down the reaction to rheostat signals (inertia);
• high temperature readings from the corresponding sensor;
• problems in the operation of the "stove";
• the fan always runs at high speed.

If the motor gets very hot, then it's time to choose a means to rinse, and choose the time and opportunities for this.

Folk remedies for flushing the cooling system

As we indicated above, there are two types of flushing agents - folk and special. Let's start with the first ones, as they are cheaper and more proven.

Lemon acid

Using citric acid to clean the cooling system

The most common citric acid, diluted in water, is able to clean the radiator pipes from rust and dirt. It is especially effective if ordinary water is used as a coolant, since acidic compounds are effective against rust, and alkaline ones are effective against scale... Remember, however, that citric acid solution will not remove significant contamination.

The composition of the solution is as follows - dissolve 20-40 grams of the substance 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). It is considered ideal when adding acid to distilled water the pH is around 3.

The cleaning procedure itself is simple. It is necessary to drain all the old liquid and fill in a new solution. Next, you need to warm up the engine to operating temperature and leave it for a few hours (or better at night). Next, drain the solution from the system and look at its condition. If it is very dirty, then the procedure must be repeated 1-2 more times until the liquid is sufficiently clean. After that, be sure to flush the system with water. Next, fill in the product that you plan to use as a coolant.

Acetic acid

Using acetic acid to clean the cooling system

The action of this solution is similar to that described above. Acetic acid solution is great for flushing rust from the cooling system. The proportions of the solution are as follows - half a liter of vinegar per bucket of water (10 liters). The cleaning procedure is the same - we drain the old liquid, fill in a new one and warm up the car to operating temperatures. Next, you need to leave the car with the engine running for 30-40 minutes so that chemical cleaning takes place in the radiator. Next, you need to drain the cleaning liquid and look at its condition. Repeat the procedure until the liquid is clear. Next, you need to flush the system with boiled or distilled water, and then fill in the coolant that you plan to use on an ongoing basis.

Fanta

Using Fanta to clean the cooling system

Similar to the previous point. However, there is an important difference here. The fact is that, unlike Coca-Cola, where phosphoric acid is used, Fante uses lemon acidwhich has less cleansing effect. Therefore, some car owners pour it instead of antifreeze to clean the cooling system.

As for the time during which you need to drive like this, it all depends on the degree of contamination of the system. In particular, if it is not very dirty, and cleaning is done more for prophylaxis, then it is enough to let the engine run for 30-40 minutes at idle. If you want to wash out old dirt well, then you can ride like this for 1-2 days, then pour distillate into the system, ride some more, drain it and look at its condition. If the distillate is dirty, repeat the procedure until the system is cleaned. Finally, do not forget to rinse it thoroughly with water and add new antifreeze.

Please note that if there are small holes or cracks in the stove piping, but the dirt has “tightened” them, then these holes may open during flushing and a leak will form.

Lactic acid or whey

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

A more affordable alternative to lactic acid is whey. It has similar properties for cleaning the radiator and other elements of the cooling system. The algorithm for using serum is as follows:

Using milk whey

• prepare about 10 liters of whey in advance (preferably at home, not from the store);
• strain the entire purchased volume 2-3 times through cheesecloth in order to filter out large pieces of fat;
• first drain the coolant present from the radiator, and pour serum into its place;
• drive 50-60 kilometers with her;
• it is necessary to drain the serum while it is hot so that the dirt does not have time to stick to the walls of the tubes again ( be careful when doing this!);
• let the engine cool down;
• pour boiled water into the radiator;
• start the engine, let it warm up (about 15-20 minutes); drain the water;
• let the engine cool down;
• pour in antifreeze that you plan to use on an ongoing basis;
• bleed air from the system, if necessary add more coolant.

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

Caustic soda

This substance is popularly called differently - sodium hydroxide, "caustic alkali", "caustic soda", "caustic" and so on.

The substance can only be used to clean copper radiators (including the heater radiator). Do not clean aluminum surfaces with baking soda.

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

Caustic soda

• remove the radiator from the car;
• rinse its insides with plain water and blow it with compressed air (not exceeding a pressure of 1 kgf / cm2) until clean water flows out of the radiator;
• prepare about 1 liter of 10% caustic soda solution;
• heat the composition to at least + 90 ° С;
• pour the prepared composition into the radiator;
• let it brew for 30 minutes;
• drain the solution;
• for 40 minutes rinse the inside of the radiator with hot water and blow it with hot air one by one (while the pressure should not exceed 1 kgf / cm2) in the opposite direction of the pump movement.

Remember that caustic soda burns and eats away at living tissue. Therefore, it is necessary to work outdoors with gloves and a respirator.

As a result of a chemical reaction, white foam may appear from the radiator pipes. If this happens, do not be alarmed, this is normal. The tightness of the cooling system after cleaning must be carried out on a cold engine, since hot water quickly evaporates, and it will be problematic to find the expected leak.

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

Coca-Cola

Using Coca-Cola as a Purifier

Some motorists use Coca-Cola to flush the cooling system from oil, emulsion, scale and rust. The fact is that it includes orthophosphoric acid, with which you can easily get rid of the mentioned pollution. However, in addition to acid, this liquid contains a large number of sugar and carbon dioxide, which can lead to certain problems.

If you decide to use "Cola" as a cleaning liquid, it is better to first release carbon dioxide from it so that it does not harm during the expansion individual nodes engine. As for sugar, after using the liquid, you must thoroughly rinse the cooling system with plain water.

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

Fairy

Some car enthusiasts use the popular Fairy household grease cleaner or its analogues to flush the oil from the cooling system. However, its use is associated with a number of problems. Firstly, its composition is designed to combat edible fat, and it simply cannot cope with engine oil. And even if you try to pour it into the radiator, you will have to fill and “boil” the engine several dozen times.

Calgon and its analogues

"White"

The peculiarity of "Whiteness" is that it contains sodium hypochlorite, which corrodes aluminum. And the higher the temperature of the liquid and the working surface, the faster the corrosion occurs (according to the exponential law). Therefore, under no circumstances fill the system with various stain removers, especially those containing bleach and its bonds (including “Mister Muscle”).

"Mole"

Known in narrow circles "Mole" is made on the basis of caustic soda. Accordingly, they cannot process aluminum radiators and other surfaces. It is suitable only for cleaning copper radiators (in particular, stove radiators) and only by removing it, by running such a cleaner through the system, you will kill all rubber seals and seals.

Other mixtures

Some motorists use a mixture of citric acid (25%), soda (50%) and vinegar (25%) for cleaning. However, we do not recommend that you do the same, as it is very rough and corrodes rubber and plastic parts.

These cleaning agents are permissible only if you need to flush the stove radiator and you do not intend to drive liquid throughout the cooling system.

Special fluids for flushing the radiator

The above means, of course, can be used to flush the radiator and cooling system of the car, but they have already outlived their usefulness both morally and technologically. Currently, manufacturers of auto chemical goods offer consumers a wide range of different cleaning products that cost quite reasonable money, that is, available to the ordinary car owner.

Types of liquids

There are several types of radiator cleaning fluids, which are classified according to their chemical composition. In particular:

• Neutral... Such liquids do not contain aggressive substances (in particular, alkalis and acids). Therefore, they are not able to wash off significant contamination. As a rule, neutral formulations are used as a prophylaxis.
• Acidic... As the name implies, their composition is based on various acids. These fluids are excellent for cleaning inorganic compounds.
• Alkaline... Here, the base is alkalis. Excellent for removing organic contaminants.
• Two-component... They are produced on the basis of both alkalis and acids. Thus, they can be used as a universal cleaning agent to flush the cooling system from scale, rust, antifreeze decomposition products and other compounds.

Do not use two different products at the same time. Limit yourself to one! Also, do not use highly concentrated alkaline or acidic compounds, as they can damage the rubber and plastic components of the system.

conclusions

As you can see, the choice of tools for cleaning the OS is quite wide. We recommend that you use professional toolsrather than different folk methods which are used to flush the engine cooling system at home when it is not possible to buy special products. This will save the cooling and other systems of your car from possible breakdowns and extend their service life. Since various acids corrode not only the sediment, but some components and parts of the OS.

Also remember that if you want to switch from one brand of antifreeze to another, then you need to flush the cooling system with clean distilled water. This is the simplest and cheapest method for preventive cleaning of the OS.

DO NOT BOIL!

In general, it is enough to ask just a few simple questions about the device and service. car engineto find out what the average motorist knows about such an important component of the power unit as the cooling system.

It is almost certain that when asked about engine maintenance, words like engine oil, oil filter, timing belt, valve stem seals, and at the same time nine out of ten respondents in their answers will bypass such concepts as coolant, cooling radiator, thermostat, water pump pump. And here we involuntarily have to admit the fact that even today the engine cooling system (as well as its maintenance) undeservedly continues to remain in the deep shadow of the oil system, connecting rod-piston and gas distribution mechanism of a car.

Well, indeed, if a high-quality and, as a rule, an expensive grade of oil was used when changing the oil in the engine, then this may even become a matter of some pride for the car owner, while talking about antifreeze poured into the cooling system is usually limited to scant remarks about it color: green, yellow, red ...

As a rule, we resort to the help of the means intended for the care and / or repair of the automobile cooling system either when time has already been lost and the radiator channels are "tightly" capped with a layer of scale and other solid deposits, or when there is an urgent need to quickly eliminate the causes of leakage antifreeze. In the latter case, the effective operation of the sealing compound also directly depends on the cleanliness of the cooling system. ...

A LITTLE OF THEORY

In the car gasoline engine when fuel is burned in cylinders, approximately 25% of the received thermal energy is spent on driving the car, the efficiency of diesel engines slightly higher, on average about 35%, but in both cases, about a third of the generated heat energy is absorbed by the cooling system. For reference: the calorific value of gasoline is such that it is enough to burn just one liter of it to boil 120 liters of water. You can try to imagine the amount of thermal energy that a car cooling system has to cope with every day, so you shouldn't be surprised that, according to statistics, in the general list of car malfunctions, the number of breakdowns associated with the cooling system takes the "honorable" fourth place.

Correct and well-coordinated operation of the cooling system is possible only if all the following conditions are met: the cooling system must be clean and hermetically sealed, the amount of antifreeze in the cooling system must correspond technical requirements a plus good work electric fan, fan switch, thermostat, water pump and heat exchangers (radiators).

The antifreeze itself must be diluted in the correct proportion with distilled water and contain in its composition a sufficient amount of auxiliary, chemically active additives, the quality of which, in fact, determines the class of the antifreeze itself.

In modern automotive world the fleet of cars with aluminum radiators of the engine cooling system is increasing every year. This trend is due to various, primarily economic, considerations, in particular, and the fact that due to the use of aluminum radiators it was possible to reduce the total weight of the car, respectively, it was possible to reduce the amount of fuel consumed by the car. In addition, aluminum radiators also look much more preferable from an environmental point of view than many of their copper counterparts. So, in their production, it is not necessary to use lead solder, and the worst thermal conductivity of aluminum in comparison with copper is compensated by a well-thought-out configuration of the radiator honeycomb.

But aluminum also has its own weakness - it is his high degree susceptibility to the process of electrolytic corrosion. In conditions when the package of anti-corrosion additives contained in the antifreeze is consumed to the end and ceases to function, there is a sharp decrease in the acid-base (PH) index of antifreeze from the permissible 8–8.5 units. up to 7 and below. At this time, the aluminum parts of the cooling system turn into a sacrificial anode and begin to rapidly corrode.

To protect aluminum from corrosion, in addition to phosphates and borates, silicate additives began to be included in the antifreeze composition, due to which a continuous anticorrosive silicate layer, approximately 1000 Angstrom thick, was formed on the walls of the aluminum parts of the cooling system. As a rule, the service life of this type of antifreeze does not exceed one and a half to two years, and the microscopic silicate particles contained in it have abrasive properties, which contributes to the premature wear of the rubber seals of the water pump and the loss of the system's tightness.

During the operation of any car, the surface of parts of its cooling system gradually begins to grow overgrown with all sorts of layers, the building material for which are corrosion products of ferrous and non-ferrous metals, oil and fat deposits, as well as decomposition products of antifreezes. As the thickness of the sediment layer increases, the heat dissipation characteristics of the cooling system deteriorate, a process of gradual clogging of the cooling radiator channels occurs, in parallel, fuel consumption increases and the likelihood of engine overheating increases.

In addition, the cooling system of any engine internal combustion, and first of all it concerns them diesel modifications (with the exception of engines with "dry liners"), constantly experiences the destructive effects of the cavitation process. During engine operation, the cylinder walls constantly communicate high-frequency oscillations to the coolant, due to which the process of formation and collapse of cavitation bubbles begins in the liquid near the cylinder walls, in other words, at this moment, short-term (about 10-6 s) pressure impulses are formed - approximately 10 MPa, while the temperature of the gas inside the bubbles at the moment of their collapse reaches +1000 ° C! It is possible to significantly reduce the speed of the cavitation process, which is destructive for the engine, with the help of modern high-quality antifreezes developed on the basis of carboxylic acids, which, thanks to their new formula, form a thin organic coating film (approximately 60 Angstroms thick) on the surface of the cooling system parts, which has the ability to "self-heal" , after one of its sections was destroyed by a cavitation impulse. It is important to note here that antifreezes with a package of carboxylate additives cannot be mixed with antifreezes that contain silicates, therefore, when replacing one antifreeze with another, the cooling system must be thoroughly rinsed from the remnants of the old antifreeze.

As you can see, many factors speak in favor of regular treatment of the cooling system with the help of special chemicals, another question: are we able to use this or that remedy correctly?

The main difficulty in cleaning the cooling system is that deposits on the inner walls of the cooling system differ in their properties. So, for example, scale and metal corrosion products are most efficiently cleaned with acidic solutions, and oil and fat deposits and antifreeze decomposition products - with alkaline solutions. Accordingly, all cooling system cleaners are divided into two groups: acidic and alkaline cleaners. The decision to use one or another drug should be made based on an analysis of the operating conditions of the vehicle or the reasons that led to a failure in the operation of its cooling system. An extremely important condition for flushing the cooling system is to maintain a balance between cleaning properties and the safety of the products used. Being highly effective, chemicals of this group should not adversely affect the sealing materials, hoses and plastic parts of the cooling system, not to mention the parts made of non-ferrous and ferrous metals. A high-quality cooling system cleaner must not only be able to effectively cope with certain types of deposits, but also form a protective chemical film on the treated surface that can slow down the corrosion process, and also provide good condition to remove destroyed contaminants when draining the flushing solution.

Below we provide an overview of preparations intended for the maintenance / minor repairs of an automobile cooling system.
