Washing engine cooling system - selection of effective tools and methods of application. We rinse the engine cooling system as it is better to wash the cooling system

And they found that the cooling fluid was darkened or contains some impurities, the fall. Another situation - for several years you have not done the engine cooling system maintenance. Not many know that the cooling system must be periodically rinsed, think about it only when problems appear. So, what to rinse the engine cooling system?

Distilled water

Distilled water

The best means for washing the engine cooling system is distilled water. It is distilled, since simple forms a scale after passing several circles. Please note that after using other liquids for flushing the engine cooling system, you need to drive the water distilled water from one to three times. The SENS engine cooling system, although different from the conventional cooling system by the structure, but it is washed as well.
The algorithm of action is as follows:

Distilled water leaves no designer in the engine cooling system.

1. We drain into a large clean capacity (in order to estimate the degree of contamination) the coolant from the radiator (plastic screw from below either from the lower nozzle) and from the cylinder block (the metal bolt in the center, its location has a lot of variations).
2. Spin drain plugs.
3. Pour into the expansion tank (and in the radiator, if there is a separate lid) distilled water.
4. We merge dirty water.
5. If the water is strongly dirty, we make another circle for 15-20 minutes, we join - look again. Repeat the procedure to pure water.

In general, it is recommended to rinse the system in a similar way with each complete replacement of the coolant.
Waskening the engine cooling system by distilled water will never damage your car. However, water is not always able to cope with the resulting raid inside the nozzles and grillers. If pollution is strong, then it is worth thinking about other methods of flushing. What is better to rinse the engine cooling system so that it is effective and safe?

Lemon acid

Lemon acid

Old and verified Dedovsky method of washing the cooling system from rust and scale. When complying with the necessary proportions, citric acid with washing the engine cooling system copes perfectly. These are important proportions, since with a larger an acid percentage in the solution, it is capable of corrosive plastic and rubber elements.
So, the flushing solution should consist of a hundred grams of citric acid and five liters of water. Accordingly, ten liters of water accounts for two hundred acid gram and so on. Small errors are possible.

When complying with the necessary proportions, citric acid with washing the engine cooling system copes perfectly.

1. We drain the coolant (if you make a wash of the SAAB 9-3 engine cooling system, then you need to disconnect the large upper and lower fumes from the radiator, pour fluids through the top nozzle).
2. Spin plugs.
3. Pour the finished solution (note that it is forbidden to pour water and pour acid, the solution must be prepared in advance and thoroughly mixed).
4. Let the engine are 30-40 minutes.
5. We drain the liquid, if necessary (strong contamination), repeat.
6. Spin plugs in place.
7. Pour distilled water.
8. Let the engine for 15-20 minutes.
9. We merge.
10. Spin.

Milk serum

Milk serum

Washing the engine cooling system serum - the process is long in time.

Another safe is washing with acid. To take advantage of serum as a reagent, it is necessary to strain it well. The liquid must be homogeneous, without pieces, otherwise there is a risk to score the system also "cottage cheese" in addition to rust, oil and sealant.
Washing the engine cooling system serum - the process is long in time. It is poured instead of the main liquid and ride it a thousand kilometers, periodically checking her appearance, color as well. If something went wrong (serum began to turn around, the engine "Zakipel") - the acid is drained.
Recommended after serum still rinse the system with water for further use of antifreeze without unnecessary impurities.

Vinegar

Vinegar table

Flushing with acetic acid more serious technique, it is capable of rinse the engine cooling system.

The use of acetic acid for washing is already a more dangerous enterprise, however, more efficient, and fast.
When washing the cooling system with vinegar, it is important to strictly observe the proportions (vinegar 9% - 0.5 liters, water - 10 liters) and prepare a solution in advance.
Instead of old antifreeze, the finished solution is poured, the engine is started at approximately fifteen minutes (up to operating temperature), fading and staying at night (or eight hours). Acid merges, the system is washed with water (distilled), fresh coolant poured.
Flushing with acetic acid is already a more serious technique, it is capable of rinse the engine cooling system from the oil than the two previous ones.

Coca Cola

Coca-Cola for flushing radiator

The flushing of the cooling system of Coca-Cola is very effective, but at the same time is very dangerous.

Coca-Cola is an orthophosphoric acid with various impurities. So, if you are interested, than rinse the engine cooling system after the sealant, know that Coca-Cola is able to dissolve the sealant slices.
The flushing of the cooling system of Coca-Cola is very effective, but at the same time is very dangerous. The drink contains a large amount of sugar, which during prolonged exposure destroys the system. Therefore, washing (better repeated) water after using the cola is mandatory.
It contains many carbon dioxide in the gas metering, which becomes even more when heated. It threatens serious consequences and can lead to leaks and. To avoid this - let out the entire gas from the bottle.
Coca-Cola when used by use, gives excellent results in cleaning the cooling system.

Chemistry for washing the engine cooling system

LAVR tool for cleaning cooling system

The main thing when washing the cooling system compliance with security measures and clear instructions.

If you compare "folk" funds with special factory compositions, then, of course, the last is better. What washing for the cooling system are presented in the market? Various. From very penny to expensive, from unknown to brands with the name. In principle, there are no frankly terrible compositions among them, unless it is a liquid from underground production. To be clear what to take, denote several the best flushing Engine cooling systems.
Washing system cooling composition Liqui Moly., like other brand products, has proven themselves well. It is usually sold in the form of a concentrate to be diluted with water (three hundred grams per three liters) or add to old antifreeze. Ten - thirty minutes to drive on the system, then drain, rinse distilled.
From the whole class of semotic flushing, you can allocate the Wick of the Hi Gear cooling system. It gently cleanses and even softens the rubber parts of the system. Falling for seven minutes, diluted with water, the dosage of which depends on the volume, which accommodates the specific cooling system (the engine cooling system is seven liter and hexadecimal).
Washing the cooling system to the LAVR tool presents different compositions: for different levels of contamination, with different additives, different operation time, means of flushing the radiator of the engine cooling system. An instruction is attached to each tool, in which it is described in detail how to act.

Wash engine cooling system - simple operation. The main thing in it is observing safety measures (do not open the expansion tank on the hot engine; do not merge liquid immediately, but give it a little cool) and clear instructions.

In addition to different techniques for cleaning the radiator, you need to still be understood, and it is necessary to wash it, and how to understand that this procedure is necessary. So how do you rinse the engine cooling system?

What clogs the cooling system

As everyone is well known, we pour water in summer in summer, and in winter antifreeze. The rule to pour distilled water is observed quite rarely, and tap water does not differ in special quality. As a result, the chemical elements present in the water, all sorts of salt harm the work of the cooling system parts, and at high temperatures, foreign substances accumulate in the channels and pipes of the cooling system in the form of scale.

Antifreezes are not formed, but they have a definition property, and the substances formed act on the cooling parts and provoke the appearance of corrosion. In addition, the radiator is located in the front of the car, as a result, the radiator accumulates all garbage, dust and dirt, very quickly scoring all channels. And if the lattice grille is an open form, then the mass of insects are added to the mud.

Cooling system when it is time to rinse?

So, it turns out that the tubes and so thin, and the contamination even reduce their inner diameter. In addition, pollutants (scale, rust, every organic and oil) have low thermal conductivity and significantly worsen the thermal conductivity of the entire system. So the whole system, the cooling engine works less efficiently and the "heart" of the machine is heated - it is time for flushing the cooling system.

Before rinse the engine cooling system, you need to be able to determine when flushing.

Basic signs:

The temperature sensor shows exceeding the temperature rate, the machine boils, while the fan works properly, and the level of antimony is normal.

However, it is not worth bringing a car to such a state, it is much easier to flush the entire system in advance when you perform another replacement of the coolant. So that there were no problems, it is enough to do it once a year or even once every three years (it depends on what you have a car).

We wash the cooling system: Coca-Cola and Lemon Acid

After the above, let's find out how to rinse the engine cooling system? As you understand, the water is not suitable, it is powerless before corrosion and accumulated. Other substances are needed: acids are struggling with rust, and the scale is removed only alkali.

To solve these problems, lemon acid is popular, familiar with any hostess.

The proportion for the preparation of the solution is the following, citric acid kilogram for 10 liters of water (however, you can take 700 grams and 7 liters, for washing this is enough). Prepared a solution - drain completely coolant and fill the cooling system with a solution with a solution with a solution. Now you need to drive a little to load the engine and the cooling system, the temperature must be maintained in the range of 70 - 90 degrees.

After 40 minutes, drain the solution and rinse the system carefully. Washing is done like this: Fill clean water, warm the car and drain the water. The whole process is repeated 2 times. Now pour the cooling fluid and enjoy trips and stable work cars.

The method of cleaning the cooling system of conventional Coca-Cola has no less popular. The whole procedure is also performed as with citric acid, but it is enough to warm the engine only five minutes. With this method, it is also important to wash the radiator repeatedly, as Coca-Cola contains not only acid, but also sugar, which must be fully washed.

Thus, at home, you have, than to rinse the engine cooling system and get rid of scale and dirt in the radiator. No one prohibits the use of special solutions. The only one needs to be aware of the meaninglessness of savings on quality, be reasonable, buying better products from solid companies.

Video: how to rinse the engine cooling system

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 stove and air conditioning radiators. 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 will require washing automotive radiatorlike you a budget option troubleshooting. The outer sink of cells 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 tool for high-quality washing 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 with 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, poured only after filtering through the gauze, after 50 km of the run merges in the hot condition, washed 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 motor Oil outside, dramatically increases labor costs when pouring inside the heat exchanger, since 10 - 20 buckets of water will be required to remove all foam;
• 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 built into the system radiator cooling in DVS Or is located next to him, 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:

• wash mixture poured into 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 heater can be washed with folk remedies or special cleaners own forces. It is enough to know which compounds in the detergent should not be, technology without removal and after dismantling the heat exchanger in all the details given in this manual.

Lubrication and cooling systems are essential components directly affecting the engine performance. In a serviceable car, the contours on which the oil and antifreeze circulate, sealed relative to each other and the fluid should not interact, and even more so mix.

If suddenly in the expansion tank, the presence of oil is found, then it is necessary to urgently conduct diagnostics and revealation of the receipt. As a rule, the lubricant can get into the circuit of the cooling system of two faults:

• Violation of the tightness between the head and the cylinder block due to the weakening of the fastening bolts, the integrity of the gasket between them, changes in the plane of the head or microcracks in the cylinder block. As a rule, the specified faults occur due to engine overheating.
• Diesels - due to disruption of tightness in the oil cooler.

In any case, when the signs of the presence of oil in the coolant is found, a competent car diagnosis and repair is needed. After the reason for mixing liquids is found and eliminated, it is necessary to remove the remains of the oil from the cooling system.

The fact is, an aggressive medium with increased acidity, which occurs when mixing antifreeze and oil will accelerately eliminate plastic and rubber parts (nozzles, gaskets, glands), and also contribute to the formation of corrosion foci and its development on metal details. Also, the oil can be in a clock and clog the channels in the cooling shirt of the cylinder block.

Just merge the contaminated coolant and pour a new one, it will be ineffective, oil residues can remain on the inner surfaces and again mix with antifreeze. To avoid the occurrence of such problems, the cooling system of the engine must be rinsed. This can be done special chemicals In the car service or independently, or resorting to people's ways.

Cleaning the system with a special auto chemical

On the Russian market There are several effective cleaning products that can be used to flush the cooling system from oil residues:

• ABRO AB-505 is a lime scale, rust and oil sediments. The volume of 354 ml is poured into the cooling system filled with water. After the engine heating to the operating temperature, it is necessary to give it to idle during half an hour. Then, drown the engine. It is necessary to flush the system on the engine installed, with an open drain crane, constantly pouring water into the radiator or into the expansion tank, until the drainage fluid becomes transparent.
• Liqui Moly. Kuhlerreiniger.-Effective means containing enzymes and seals intended for dissolving and removing scale and contamination (including thick lubrication) from the cooling system and neutralizes acid. There are no aggressive alkalis and acids, so it can be applied to apply it for each replacement. It is neutral to rubber, metal and plastic. To clean, it is necessary to pour fluid into the system (one jar on 10 liters of antifreeze). Then warm the engine and give it to work on idling 10 - 30 minutes. A flooded fluid is allowed to leave in the system for a period of up to three hours, and the time of using the machine. After draining the old antifreeze, the system should be rinsed with running water and you can pour a new one.
• Lavr is a set for a two-step, full flushing. Specially designed to work with very complex pollution and consists of two bottles:
  1. Purifier Rust and scale (first stage) - Possible into an empty system, and then it is filled with clean, preferably distilled water, to a minimum level. Then you need to warm up the engine and leave it to work for half an hour.
  2. Cleaner oil-emulsion sediments and various residues of decomposition of old coolant (second stage). After draining the first solution, the liquid from the second bottle is poured into the system, and the system is replenished with water to a minimum mark. The car boils, heating and leave to work half an hour. Then the solution merges, the system is again filled with clean water, the engine warms up and leave it to work for 15 minutes. The last procedure should be repeated until the system begins to merge pure water And after that, you can fill the antifreeze system.

If there has been a slight contamination of antifreeze with oil products, then other Washing fluids LAVR are classical (Classic), for commercial vehicles (Fortrucks) and synthetic (SynTetic) which are also designed to remove traces of oil.

In addition to the flushing listed, you can choose analogs and other manufacturers - Bizol, Pingo, CRC. All of them effectively dissolve various contaminants and do not damage the details and components included in the cooling system.

Wash engine cooling system by people

There are exotic and less civilized washing methods invented by folk crafts when special auto chemicals were not so available.

Instead of contaminated antifreeze, the serum is poured into the system, slightly above the minimum level in the expansion tank (up to 10 liters can be consumed). In time, how much to keep in the engine serum there is no one opinion. Someone travels with a filled serum 200-300 kilometers, then it is merged. Someone advises to pour her away, warm the engine and leave it to work in a half for a period of 5 minutes to one hour.

If the fusion fluid is very dirty and with oil bunches, then serum washing procedure can be repeated one of the above methods. After washing, you must shed the system with running water, pour clean water, once again warm the engine and give it to work for about 5 minutes. If the fluid is pure, then you can pour a new antifreeze.

Carbonated drinks

Cola, sprite and yard contain orthophosphoric acid capable of dissolving almost anything. Mixing is produced in the following proportion - half of the volume of water or antifreeze and the remaining part is the drink. The engine is heated and allowed to work for five to six minutes. Then the engine is devoured, and leave to half an hour to estimate.

After draining the soda, it is necessary to produce a long washing of the system with water to wash out the remaining sugar.

Lemon acid

For the cleaning, lemonic acid It is necessary to dissolve in water at the rate of 1 kg of powder per 10 liters of liquid. With a small contamination, the amount of acid can be reduced to 500 grams.

With a poured solution, with medium turns, the engine should work for 15-20 minutes, and then give it to settle approximately 45 minutes. After the drain, it is also necessary to rinse well with running water system.

Various household detergents for dishes are very well laundered fat and oil from any surfaces. To wash the cooling system, they are also used. Intellight of any means be added to the system, with severe contamination, you can pour a full half-liter bottle.

The liquid must be dissolved in water and pour into the cooling system. Heat the car and leave to work for 15 minutes. If the fluid plum contains a large amount of oil, you can repeat the procedure several times. Alternatively, with such a flooded solution, you can ride a car for a couple of days or about 100 km.

When the system starts to merge clean water (without visible oil impurities), then rinse the system with running water and you can fill fresh antifreeze. Household detergents have increased foaming, so when warming up the machine with a flooded solution, it is necessary to control the expansion tank and the tapered neck of the radiator.

What is the cleaning method to choose

If you choose than rinse the cooling system from the remaining oil, it is more effective, it is more profitable and safer will be used to use flushing fluids. They are specially designed for cleaning and do not contain substances aggressive to engine parts and cooling systems. Accordingly, they cannot harm the details. According to the cost, buying a flushing is often cheaper than folk remedies. Listed special preparations are in the price range from 200 to 600 rubles.

Cleaning by folk remedies does not guarantee good result. On the Internet on the forums you can find a lot of discussions as people helped someone, and there is no one. Their use can not only help, but to harm. For example, orthophosphoric acid contained in carbonated beverages can destroy nozzles and seals.

Output

When washing the engine, fill the cooling system, as well as liquid drains, it is necessary to produce when the engine is cooled, in order to exclude the possibility of damage to the engine from the temperature difference and getting a burn when entering the skin.

The correct operation of the car cooling system determines the quality of the engine engine function. The use of optimally selected antifreeze eliminates the likelihood of overheating of the motor. Over time, the channel channels begin to clog. As a result work in the DVS. It may be broken. How to flush the cooling system (CO) and what methods for this can be used, find out from this article.

[Hide]

Why and when should I wash the car cooling system?

The flushing of the cooling system of the DVS must be performed in case of clogging. Co includes a number of components that must work correctly and interact with each other. This will allow antifreeze cooling the hottest elements. power aggregate. The most vulnerable component of the cooling system is nozzles. Over time, they are clogged and destroyed as a result of exposure to high loads.

In the process of using the machine in motor compartment Sand, crushed stone, stones from the road, as well as insects, which leads to the formation of dirt on the unit. As a result, part of the pollution appears in CO and mixed with the consumable material. This contributes to the formation of scale on metal components of the system, which over time peeling and fall into the nozzles. As a result of the highway, they begin to be clogged, and this helps to reduce the effectiveness of the CO, in some cases it is possible its full failure.

Contaminated radiator s Skip on the radiator device Deposits in SO Nozzles from before and after cleaning

Properly performed flushing will effectively remove contamination from highways. You can learn about the need for cleaning by the appearance of the antifreeze indicator on the control panel. If the light bulb caught fire, it may indicate not only the absence of consumables, but also on the presence of problems in the work of CO. The rinsing process specialists are recommended to perform at least every two years.

Determining the degree of clogging

There are several ways that allow you to determine the degree of pollution from:

1. Engine inspection. His overheating can be associated with different reasonsBut the lack of cooling the power unit is one of the main. If the motor is constantly overheated, you need to diagnose the cooling system.
2. Check expansion tank. The degree of clogging can be determined by the presence of a precipitate in the tank. But for this, the container will have to dismantle. Determine the presence of deposits on the reservoir installed under the hood is hardly possible. You can try to shine a flashlight on the container. If the sediment layer is visible at the bottom, then it is time to rinse.
3. Tracking the condition of the coolant. The presence of rust and traces of scale in the coolant indicates the need to replace refrigerant and clean CO.
4. Inspection of hoses. Close nozzles can be determined by disconnecting one of the hoses. Be careful because the refrigerant will start out from the highway. If you see that clogging inside the nozzle interferes properly passing the consumable system on the system, then flushing should be flushing.

Methods for washing

To clean the cooling system, you can use the services of specialists to a hundred. But in this procedure there is nothing complicated, so we propose to learn how to fulfill such a task yourself. Effective flushing can be performed as using special fluidsand under handicrafts. Below we will tell about what you can rinse from at home.

Using water

Water - Let it be not the best tool, but the most accessible for car owners option. But for washing, it is necessary to use not ordinary liquid, namely distillate. The fact is that the composition of the tap water may be present molecules and substances that aggressively affect the rubber elements of the CO. If part of the fluid falls in the system, it will lead to the destruction of rubber components.

The process of cleaning the distillate is relevant for all cars, whether Daewoo Sens or Mercedes, and it is performed as follows:

1. Cool the engine. The procedure is performed on a cold motor, so wait until ICA will cool.
2. We remove the material used. To get rid of the old antifreeze, you need to unscrew the plug and wait until the expenditure is completely out of the system. Do not forget under drain hole Install the tank for collecting the fluid being drained.
3. Fill with water. We twist the cork and pour into with distilled water using the expansion tank. The volume of water must correspond to the volume of the coolant fusion.
4. Flushing process. We start the motor, let him work for a while. You can even ride a little. It is desirable that the engine worked about 15-25 minutes.
5. We merge water. If it is too dirty and there are traces of deposits and scale, then the cleaning procedure is desirable to repeat. When clean water is out of the system, it will become clear that the result is achieved. Now you can pour a new antifreeze.

Advantages and disadvantages

The main advantage of this method is its availability and low cost. Find distillates is not a problem. The disadvantage of this method is that its implementation is more relevant in preventive purposes when the level of pollution is small.

Artem Petrov provided detailed instructions on cleaning CO.

Use of acids

Wash with a lemon or solution of orthophosphoric acid. This option is especially relevant for those car owners who want to clean the system from the remnants of sealant or oil. The cleaning procedure is performed in the same way as water.

To carry out the problem of removing contamination, the kilot should be taken into account the following nuances:

1. Proportions. To make a solution for cleaning a strongly contaminated system, 1 kg of acid and 10 liters of water will be required. With air pollution, the volume of acid can be reduced to 800 grams per 10 liter of liquid.

Technical features. The procedure is performed in the same way as when washing with water. After the gulf of the solution in CO, it is necessary for some time to ride a car. Give the Motor to work as on idlingand in terms of loads. After the trip, fuel the engine and leave the car with an acid with an acid for 45 minutes.

Careful flushing. After draining the solution, rinse with the usual distillate. To do this, repeat the cleaning procedure 3-4 times.

Advantages and disadvantages

To carry out the washing, this method will have to be spent. In addition to 20 liters of distilled water, you will need to buy citric acid. The average cost of one kilogram is 1-2 dollars. Note: If you are overdoing with proportions, the acid can dug nozzle and gaskets.

Use of vinegar

With your own hands, you can clear the system with the use of vinegar. It is important to observe the proportions: half of the liter of vinegar is added to 10 liters of distillate. Cleaning lies in the bay of the solution in accordance with the further warming of the power unit up to 100 degrees and its stop. After that, the car is left for approximately 8-10 hours. Merging fluid, pay attention to its condition. If there are traces of rust and scale, as well as dirt, then the procedure is repeated. When the cleaning is completed, the unit is washed with distillate.

The flushing procedure with vinegar is represented on the video, removed from the channel "Total gradually".

Advantages and disadvantages

Plus is low cost. Vinegar is cheap, so you do not have to spend very much for such a flushing. The main drawback is that this process takes a lot of time. If the contamination of the engine is serious, then you will have to spend on cleaning for several days.

Soda caustic

The use of this option is relevant to clean the radiator device and the heater. The use of soda is allowed exclusively on the details performed from brass or copper. If your car is equipped with an aluminum radiator device, caustic use is not allowed. This tool can be used for cleaning the cooler shirt. When performing this method, observe the proportions: in one liter of distillate, plump about 50 grams of soda. Before cleaning, the radiator device must be dismantled.

Advantages and disadvantages

The positive properties include its significant cleansing effect. The caustic soda is a strong substance that almost no contamination may not resist. The price is low enough, which is also an advantage. The main disadvantage is that the substance is unsafe. When working with it, it is necessary to follow the precautions throughout the cleaning procedure.

Milk serum

This tool is characterized by the presence of elements in its composition, the chemical features of which allow to dissolve sediments and scale, while not affecting negatively on the rubberized components of the cooling system. Before pouring serum in CO, it is necessary to strain through the sieve. After the bay of serum on it you should drive about one thousand kilometers. After draining the liquid, the system should be washed with distilled water and pour antifreeze corresponding to the engine specification.

The Channel "Country Master for All Hands" showed the result of washing serum washing.

Advantages and disadvantages

The main advantage of the method is its effectiveness. Serum will also well fix the mains of the cooling system and the radiator, as well as specialized means. The disadvantage is that the cleaning process takes a lot of time. If you need to rinse the system urgently, this method is not suitable. Its fulfillment is also impossible in the cold season, since serum frozen will quickly freeze, and this may lead to more serious consequences. In addition, after the bay, you will need to check its condition from time to time and be sure to monitor the operating temperature of the FEA.

Washing with Coca-Cola

As the reviews show, the use of Coca Cla is considered one of the effective methods of contamination. The product includes orthophosphoric acid, which quickly copes with rust and scale. Be careful because there are sugar in the coland, and it clogs the system highways and the radiator device. The flushing process is also performed as with conventional water. After applying the drink with once again cleaned by distillate.

Advantages and disadvantages

The dignity is effective. But due to the acid content in the composition of the beverage there is a possibility of the destruction of rubber components and pipes of CO. Coca-Cola - liquid product with gases. As a result of the heating of the motor to the operating temperature, the gases will be expanded, and this can be destroyed to affect the operation of the motor. Before flooding a drink into the cooling system, we recommend unscrew the cork and wait a few hours until the gases come out. Another minus is high cost.

Chemicals

For cleaning, you can use special flushing tools, for example, Hi-Gear or Liqui Moly. Assortment of such products is large. Soft rinsing chemistry does not affect the state of the radiator and the CO hoses, and it allows you to perform the cleaning system quickly.

There are several types of chemicals:

1. Neutral. In the composition of substances there are no aggressive molecules. Such flushing are not as effective compared to other consumables, their use is more relevant to prevent.
2. Alkaline. Feedback show that such products are well removed organic pollution. You will not be able to find them in an undivided state.
3. Acid. Very aggressive to the components of the cooler system. Their operation is relevant to remove scale, as well as inorganic pollution.
4. Two-component. As part of such funds there are alkali and acid. These products are consistently poured into CO and allow its effective cleaning from any type of dirt.

Advantages and disadvantages

The advantages should include a huge choice of funds and their effectiveness. In practice, chemistry is always better cleaning cooling systemthan other liquids. Moreover, its use will allow you to quickly achieve the result. By cons carry a high cost of funds.

To prevent problems in your work, consider the following nuances:

1. For washing, it is impossible to use water from the tap.
2. To create a solution, only the use of distillate is allowed.
3. Pour the cooling system only high-quality consumables, do not save on the purchase of antifreeze.
4. Periodically carry out the visual diagnosis of refrigerant for the presence of deposits, dirt and scale, as well as traces of rust.
5. Change the liquid in the system at least every 3 years or after 40-80 thousand km of mileage.
6. When replacing the consumable material, clean CO.
