Before we proceed to the direct description of certain funds, I would like to remind how important it is to make a regular flushing of the car cooling system. The fact is that, depending on the coolant used on the walls of the tubes, of which the radiator consists, the rust is accumulated, oil sediments, antifreeze decomposition products, and scale. All this leads to difficulty circulation of coolant and decrease in heat transfer. And this always badly affects the characteristics of the engine and increases the wear of its individual parts with the risk of their premature failure.
It is worth noting that the washing of the system can be both internal and external (external cleaning implies the radiator washing outside from the particles of dirt, dust, insects on its surface). It is recommended to make the internal flushing of the cooling system at least once a year. It is best to do this in the spring when there are no frosts, and ahead of the hot summer is to come.
On some machines on dashboard There is a light bulb with a radiator image, the luminescence of which may indicate not only a decrease in the level of antifreeze, but also that it is time to change. This can serve as a signal and to the fact that the cooling time of the cooling system has come. There are also a number of indirect signs of the onset of such cleaning:
Radiator icon, signing about problems in the cooling system
- frequent engine overheating;
- problems in the work of the pump;
- slowing the response to the rigging signals (inertia);
- high temperature testimony from the corresponding sensor;
- problems in the work of "stoves";
- the fan always works on high revs.
If the motor is very hot - then it's time to pick up the tool in order to wash the cooling system, and choose time and opportunity for this.
How to rinse the engine cooling system
The process of flushing the cooling system is quite simple, and it consists of next stages: The car engine warms a little, after which it turns off and you need to wait for a while until it cools off; Next, the plug is unscrewed, the old cooling fluid merges from the motor. Attention: Do not drain the cooling fluid on the hot engine - it is fraught with burns and spray antifreeze under pressure; After that, you need to pour the means for cleaning the cooling system. Some of them need to be diluted with distilled water. If you use lemonic acid or coca-cola for washing, specific recommendations on the use of database data for washing the engine will be given below.
In the case when specialized funds are applied, you must follow the instructions on the package; Next, some time you need to give the engine to work with a flooded tool for cleaning the cooling system. The time recommendation depends on the type of fluid used; After washing the liquid merges, and the cooling system is poured pure waterTo remove the remnants of the detergent. The water-bay procedure may need to repeat several times; Recent step A new cooling fluid is poured into the cooling system. ATTENTION: Choose antifreeze is better as the same that was covered in the cooling system before washing. Careful flushing of the cooling system is necessary to derive the resulting precipitation, dirt, corrosive elements and harmful impurities that can lead to a violation of the stability of the system. We strongly recommend floating after washing the cooling system new antifreezeSince in the old liquid, even if the car drove it not so much kilometers on it, there are particles of contamination.
What to rinse the engine cooling system at home?
Rinse the engine cooling system with the following liquids:
Distilled water;
Acidified water;
Special tools for washing the engine cooling system.
The choice of cleaning tool depends on the state of the car.
It is necessary to engage the engine cooling system or in the summer on the street or in winter in the warm box. To start, drain the old antifreeze from the system - this process is described in detail in the instructions for replacing the coolant. If briefly, the following algorithm is as follows:
If the motor is hot, it needs to be able to cool.
Put the car on a flat surface.
To protect your hands from hot engine elements and cooling systems, it is better to wear gloves.
Open and fix the hood.
Under the radiator, you need to put the tank for collecting the old coolant.
Afterverting drain plugs, drain the antifreeze in turn from the engine and the radiator.
In the form of a fusion fluid, it is possible to draw conclusions about the state of the cooling system as a whole. In the merge of antifreeze, different particles may be present (scale, rust and the like). 
Chemistry for washing the engine cooling system
The laurel means for cleaning the 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.
Folk detergents of the cooling system
As we indicated above, there are two types of washing products - folk and special. Let's start with the first as cheaper and checked.
Lemon acid
Using citric acid to clean the cooling system
The most common lemon acid, divorced in water, can clean the radiator tubes from rust and dirt. It is especially effective in case of conventional water as a coolant, since acid formulations are effective against rust, and alkaline - against scale. However, remember that citric acid solution is unable to remove significant pollution.
The composition of the solution is the following - 20-40 grams of matter dissolve in 1 liter of water, and if the contamination is strong, then the amount of acid per liter can be increased to 80-100 grams (a larger volume is created in a similar proportion). An ideal option is considered when with the addition of acid into distilled water pH level is located in the area 3.
The cleaning procedure itself is simple. It is necessary to merge all the old liquid and pour a new solution. Next you need to warm up the engine to operating temperature And leave it for several hours (and better at night). Next drain the solution from the system and look at its condition. If it is very dirty, then the procedure needs to be repeated 1-2 times until the fluid is quite clean. After that, it is necessary to rinse the system with water. Next, pour the tool that you plan to enjoy as a coolant.
Acetic acid
Using acetic acid for cleaning the cooling system
The effect of this solution is similarly described above. Acetic acid solution is perfect for flushing the cooling system from rust. The proportions of the solution are the following - half-liter vinegar on the water bucket (10 liters). The cleaning procedure is similar - we drain the old liquid, pour a new one and warm up the machine to operating temperatures. Next you need to leave the car with a running engine for 30-40 minutes So that chemical cleaning occurred in the radiator. Next, you need to merge the cleaning liquid and look at its condition. Repeat the procedure until the fluid becomes clean. Next, it is necessary to wash the system with boiled or distilled water, after which it is planted to pour the coolant that you plan to use on an ongoing basis.
Fanta.
Using phantas for cleaning the cooling system
Similar to the previous item. However, there is an important difference. The fact is that, unlike Coca-Cola, where orthophosphoric acid is used, in "Phanta" used lemon acidwhich has a smaller cleansing effect. Therefore, some car owners for cleaning the cooling system pour it instead of antifreeze.
As for the time, during which you need to ride, it all depends on the degree of contamination of the system. In particular, if it is not very contaminated, and cleaning is done more for prevention, it is enough to make the engine for 30-40 minutes on idling. If you want to wash the forged dirt well, you can ride so 1-2 days, then pour a distillate to the system, ride more, merge it and look at his condition. If distillate dirty - repeat the procedure until the system is cleaned. At the end, do not forget to rinse it well and pour a new antifreeze.
Please note that if there are minor holes or cracks in the stove pipeline, but the dirt "tightened" them, then when washing, these holes can open and flow. Therefore, after washing, make the audit of the system pipelines.
Milk Acid or Serum
An excellent option for washing the cooling system of the car engine is lactic acid. However, a significant problem is the fact that it is very difficult to get a milk acid today. But if you manage to get this substance, it can be poured into the radiator in its pure form and for some time to ride on it (or give the car to stand up with a running engine).
More affordable alternative lactic acid is dairy serum. It has similar properties for cleaning the radiator and other elements of the cooling system. Serum using algorithm:
Use of lactic serum
- prepare in advance about 10 liters of serum (preferably home, and not from the store);
- strain the entire bought volume 2-3 times through gauze in order to filter large slices of fat;
- pre-from the radiator merge the coolant existing there, and to pour serum to its place;
- drive with her kilometers 50-60;
- serum is needed in hot, so that the dirt does not have time to stick to the walls of the tubes ( observe Caution!);
- give the engine to cool;
- pour into the radiator pre-boiled water;
- run the engine, give it to warm up (about 15-20 minutes); merge water;
- give cool engine;
- pour antifreeze that plan to use on an ongoing basis;
- release air from the system, if necessary, add the cooling fluid.
Please note that serum has its cleansing properties within 1-2 hours. Therefore, those mentioned 50-60 km must drive during this time. It makes no sense longer to ride, as the serum is mixed with mud located in the system.
Caustic soda
This substance in the people is called differently - sodium hydroxide, "caustic alkali", "caustic natter", "caustic" and so on.
The substance can be used only for cleaning copper radiators (including for the stove radiator). Soda can not clean aluminum surfaces.
In accordance with the official instructions of the manufacturer of copper radiators, it is necessary to act on the following algorithm:
Caustic soda
- remove the radiator from the car;
- rinse its insides with simple water and bleed with compressed air (not exceeding the pressure of 1 kgf / cm2) to the state when clean water will flow out of the radiator;
- prepare about 1 liter of 10% of the solution of caustic soda;
- heat the composition at least to + 90 ° C;
- pour the cooked composition into the radiator;
- give him broken 30 minutes;
- drain the solution;
- for 40 minutes, flushing the insides of the radiator with hot water and blow by hot air alternately (at the same time the pressure should not exceed 1 kgf / cm2) in the opposite direction of the pump operation of the pump.
Remember that the caustic soda causes burns and corrosive live fabrics. Therefore, it is necessary to work on the street in gloves and the respirator.
As a result chemical reaction White foam may appear from the radiator pipes. If this happened - do not be scared, this is a normal phenomenon. The tightness of the cooling system after cleaning must be carried out on a cold engine, as hot water evaporates quickly, and find an alleged place of leaks will be problematic. 
Wash engine cooling system by distilled water
We want to immediately note that this is the most inexpensive method of washing the engine cooling system, but at the same time it is the least efficient. At the cost of time and forces, washing with distilled water takes not the first place. However, in some cases, this method will be fully justified.
Naturally, simple water from under the tap for flushing the engine cooling system cannot be used. There should be exceptionally distilled water or, at worst, boiled at least 20 minutes (it has in its composition at least salts).
Washing system of cooling is carried out elementary:
Pour distilled water into the radiator.
Get the car and give her to work in good order for about 15-20 minutes.
Jump the engine and merge water from the cooling system.
Such a procedure must be repeated several times until the water becomes clean. This method is only when the machine is relatively new, and there are no obvious contaminants in the antifreeze.
Wash engine cooling system is an important regular procedure necessary when passing. Control the volume of antifreeze in the system (maintaining the average level in the expansion tank) and cleaning the technological channels special means Provide the optimal temperature and long-lasting operation of the engine.
Be sure to read the article of our specialist, which tells about what is better -.
For more information on how to breed, you can find in the material of our expert.
When it is necessary to rinse the engine cooling system
The constant operation of the fan on the cooling radiator and the failure of the heating system is evidence of the contamination of the technical channels of the engine. Eliminate the problem is necessary in as soon as possible. This can be done with your own hands.
The need for flushing the engine cooling system indicates a number of features:
- regular overheating and problems with the subsequent launch of the power unit;
- slow response to the RESOTATING signal;
- high readings after starting the engine;
- work pump with constant interruptions;
- changing the shade of the cooler in the tank.
When such signs occur, it is necessary to immediately change the liquid for flushing the engine cooling system.
Clean the system can be used with household tools or special chemical additives.
Working coolant has a tendency to "bipping". In the system circulates Tosol, distilled water or antifreeze is workers coolers that are controlled by marks in the tank and are periodically fastened. Overheating and swallowing leads to the loss of coolant properties (coolant), the formation of plaque in pipelines and on the inner walls of the radiator.
Possible causes of scoring:
- dust and mechanical splashes;
- chemical sediments;
- salting formation (with a tap of ordinary water);
- corrosion of the material of internal elements with with falling into a closing precipitate.
Change color and odor - signals to replace distillate. When consistent with consistency, the appearance of extraneous enclosures or the formation of a polluted emulsion must be immediately used to flush the engine cooling system.
General rules
The soft flushing of the engine cooling system can be made by distilled water. To remove scale from the walls of pipelines, special solutions will be required.
The car is installed on the site. The process starts with a plum of old coolant. At the bottom of the radiator and on the cylinder block unscrewed special drain plugs. The exhaust antifreeze or antifreeze is poured into a pre-substituted container.
In order to avoid burn, plums are spent on the cooled engine.
The system is washed with distilled water or a weak special solution. For cooking you will need one of the components:
- soda;
- vinegar;
- lemon or lactic acid.
Sometimes "Coca-Cola" is used, but should be carefully referring to such a process. "Cola" aggressively affects the inner walls of the radiator.
The engine will need to start and drive a liquid for about 10 minutes. Upon completion of the process, rinse with distilled water, and then pour a new toosol or antifreeze.
Flushing with homemade means
Preventive work on the elimination of scale and dirt is carried out every 6-12 months. IN soviet time There was a regular cleaning of technical channels "acidified" water. Food soda, citric acid and vinegar used. The solution was made of a small concentration so that the inner walls were not oxidized in the aggressive environment. Works were carried out cautiously, taking into account the pollution of the channels. Such methods remain relevant today, and the process demonstrates the desired effect.
If you do not wash the cooling system, you can encounter unpleasant problems:
- breakdown of distillate heater;
- unstable work of heating stove;
- clogging of the water pump.
To avoid crying consequences, you need to figure out than washing the car cooling system. Modern methods of cleaning on large one hundred are based on the use of special expensive compositions. Their use spectrum is designed to remove all possible contaminants, allows you to get rid of organic sediments and rust.
Additives are produced on the basis of two-component compositions. There are neutral variants consisting of an acidic or alkaline solution. Additives involve aimed at eliminating a specific type of pollution.
Flushing with distilled water
After plum, the old coolant is filled with distilled water.
Need:
- close the valves on the radiator and the cylinder block;
- make a car;
- hold the engine in idle mode - up to 20 minutes;
- wait for cooling and re-procedure.
Flushing is considered completed when distillate at the output will be cleaned of foreign inclusions. This method allows you to wash the accumulated dirt, but will not clean the channels and the inner plane from deposits.
How to wash the engine cooling system with citric acid
It is necessary to prepare a concentrated solution. The calculation is made in the optimal proportion - 200 grams of citric acid per 10 liters boiled water. The composition is poured into the expansion tank until the system is fully filling, but not higher than the maximum level.
In order for the solution to warmer and joined the reaction, you need to drive a few kilometers.
The temperature of the coolant is controlled on the sensor. The cleavage response is effective at T 80 degrees. After cooling the engine, repeat the process with a smaller concentration of the solution (100 g per 10 liters of water). The next flushing is carried out with clean water, and after the antifreeze or toosol is poured.
Flushing with acetic acid
Effective procedure and table 9% vinegar. A bottle of 0.5 liters is dissolved on a bucket of boiled water. The procedure consists of stages:
- warm the engine about 30 minutes;
- leave the refill system at least 8 hours or at night;
- merge the waste liquid and make a flushing with distillate.
When pouring antifreeze, stroke air bubbles from the cooling system.
Flushing with breast serum
Option with lactic acid or serum - effective method OS cleaning It will take a car to work in the active mode (on the average engine speed) about half an hour or drive 40-50 km without stopping.
Home serum is more effective "purchased." You will need to strain it several times through a thick layer of gauze. It is possible to filter through a sieve, but with a shallow cell.
The serum is poured into the radiator in its pure form, without dilution with water. After washing, pour water and re-pass 5-10 km. This is necessary to remove the dried dairy products in technological channels. Making sure to clean the OS, pour the clean distillate.
Cleaning soda is a thorough and special procedure. The negligent approach can lead to excessive oxidation of metal and rubber parts. The procedure is resorted to 1 time per year or after passing a kilometer of 50-60 thousand km. Special attention Pay the ratio of the components of the combined solution:
- 3% of caustic soda;
- 7-10% calcined soda;
- 85-90% boiled or distilled water.
After filling the system, you will need to drive up to 100 km, but do not leave a soda solution in the radiator more than 1 day.
10 liters of water use no more than 1 kg of food soda.
When using a sodium bicarbonate solution, it is necessary to thoroughly rinse the system several times. Making sure the final cleaning from pollution and salt sediments, pour a new distillate.
Flushing with Coca-Cola
The people's method involves the use of Coca-Cola carbonated drink. This is an effective way with your own nuances. The drink contains orthophosphoric acid, which reacts with polymer parts from the engine. The minus method is a large content of sugar in the "cola", which, when overheating, is deposited on the inner walls of the metal elements of the pipeline.
Features:
- before use, release all carbon dioxide from soda;
- the circulation of fluid in the engine running is not more than 15 minutes at T less than 100 degrees.
Despite the good quality cleaning, you should not often resort to this option. With frequent application, the negative effect of "cola" on rubber pipes was revealed.
Washing with special means
On the market car details There are several additives for CO. Special tools are 4 types:
- acidic;
- neutral;
- alkaline;
- two-component.
The additives are characterized by the concentration of chemicals and the aggressiveness of the effect on the internal parts of the engine.
An important component of the engine node internal combustion cooling system that is refilled or toxol, or antifreeze, or water (mainly cargo workers domestic cars We are filled with water in the north, so they do not devour the engines all the cold season).
Wash engine cooling system.
Antifreeze, mainly have an operational period of 5 years or until the engine will pass 250 thousand km. Tosol has a service life of 2-3 years. By the way, you can see what will happen if mixed. Depending on the operation of the car and the quality of the coolant, if not changing the liquid or, if you dilute the cooling fluids, the radiators and the cooling shirt are clogged. Therefore, to increase the engine's interremary resource, it is required to periodically wash the engine cooling system. You can rinse both in car services and at home in our own garage.
Many drivers clean the cooling system with their own hands. Someone uses citric acid, someone Coca-Cola, someone's diesel fuel, someone uses special needs (eg Lavr), someone else something.
Who wants that he does not have any problems with the engine, it should regularly flush the cooling system with a certain periodicity. During the engine operation on the walls of the radiator and nozzles, deposits, rust, oil sediments, precipitation and scale are collected. The litters will be much more if the engine worked in high mode, the temperature almost reached the red mark.
If the channels of the radiator and nozzles beat, then, accordingly, circulation has deteriorated. And the poor engine circulation will create additional problems: the engine will overheat (which can be for replacing the gasket), the stove will blow cool air, the parts of the motor are subjected to increased wear.
It is advisable to rinse the cooling system of cars 1 time per year. To replace the coolant, warm weather is needed.
On the instrument panel there is a cooling radiator icon, which, if on, speaks either a low level of antifreeze or antifreeze, or that the radiator must be cleared or replaced. This icon is available in some brands of cars.
List of cars, we were viewed in another article. It contains brands and models of machines and the necessary volumes of the coolant for them.
Signs that it is time to clean the cooling system.
If one of the following features is detected, then it is necessary to make the system cleaning cooling in DVS:
- The engine temperature rises sharply, and it happens often.
- At the operating temperature of the motor from the stove blows cold air.
- POMPUT POMP (pump).
- The fan turns on and runs on high speed.
When such signs and reasons appear, it is necessary to study the flushing circuit, how to rinse than rinse how to properly pour a new cooling fluid.
Wash engine cooling system with their own hands.
The means used to flush the engine cooling system are used both chemical specials and folk. Folk remedies for cleaning the system - inexpensive and repeatedly proven. Acid-containing means are able to clear from rust and such sediments, and alkaline means - from scale.
Consider the washing with citric acid.
Since citric acid (Formula C6H8O7) is able to destroy rust and deposits of oxidized metals, it is effective to use it if the coolant in the cooling system was used water.
How to breed citric acid for flushing radiators:
- We take one liter of pure water.
- Add 20-40 grams of citric acid powder to this water (1-2 tablespoons) - it is for easy cleaning or prevention. If the system has not been washed for a long time, it has strong contaminants, then it is necessary to add to 1 liter of water 80-100 grams of citric acid (8-10 centuries). So that the water has become strongly acidic, not alkaline, that is, the pH level so that less than 7. If you add this amount of citric acid into distilled water, then the pH level will be about 3.
- Make the volume of the finished liquid as it climbs into an empty cooling system. Depending on the engine. How many liters were flooded toxol, water or antifreeze, in the same volume it is necessary to prepare a cleaning liquid. That is, to prepare 10 liters of citric aggressive fluid, 10 liters of distilled water and 0.8-1 kg of lemon powder will be required.
Follow the flushing of the cooling system:
- Fully merge the cooling fluid from the system.
- Pour the cooked solution.
- Run the engine, heat up to the operating temperature and leave for several hours.
- Drain the liquid from the cooling system.
- If the liquid is very turbid and dirty, then it is necessary to wash again, until the fluid becomes transparent.
- After the fusion flushing folk fluid turned out to be clean, then it is necessary to wash the system with conventional clean water (preferably distilled or boiled).
The next common folk remedy for flushing the engine cooling system is acetic acid.
Acetic acid solution effectively removes rust. To prepare a washing solution, you will need:
- 10 liters of pure water;
- 0.5 liter of vinegar.
The procedure for replacement is the same as using citric acid:
- merge;
- pour;
- launch the motor;
- give the engine about 1 hour;
- merge;
- repeat until the fluid becomes clean;
- rinse with distilled or boiled water;
- pour a new antifreeze or toosol.
Another folk remedy as a flushing fluid of all channels of cooling systems is a carbonated beverage Fanta (Fed).
As part of the phantas there is citric acid. Therefore, it is also used for cleaning some home masters. They merge the old liquid, poured the entire system by this phantha, then they give a motor for about an hour at idle or, if strong contamination, then operate a car with a poured phantom couple of days. After that, distilled water is drained and poured, and also exploit the day two. Then drained, and look at the state of the liquid. If necessary, they do the procedure until the fluid is being drained, relatively, clean.
After washing, you need to check all the cooling system tubes and the radiator. It happens that the rust overlapped the holes and the system remained hermetic. But after washing, can flow the radiator or tube.
Washing the cooling system with lactic acid or serum.
The variant of using serum or lactic acid is less common as the washing fluid of the engine cooling system.
If there is a lactic acid, it fills the entire system. Run the engine and give some time to work on idling or under load.
But, not everyone has the opportunity to use lactic acid for flushing. Therefore, serum is used instead.
Serum cooling system flushing sequence:
- Find or prepare 10 liters of serum.
- Strain several times so that there are no fat pieces.
- Merge old coolant.
- Pour serum.
- Start the engine and go on the road. Drive 50 kilometers, but ride no more than 2 hours. Because the main good properties serum loses after 2 hours.
- Wear tight rubber gloves so as not to burn.
- Merge hot serum. If cooled, then on the walls of the channels, the shirts of the cooling system are again formed deposits.
- After plum, give the motor cool.
- Pour pre-boiled water into the system.
- Run the motor.
- Give work for about 20 minutes.
- Merge water.
- Pour fresh antifreeze G11, G12, G12 + or G13. It is better to fill from G12 and higher.
- Exhaust air. This also requires certain knowledge -.
- Check the level, add, if necessary.
The next folk remedy for cleansing the cooling system of the engine is the caustic soda.
Caustic soda, she "caustic alkali", she is the sodium hydroxide, it is caustic - effective toolBut only for attention! - copper radiators. Soda compositions are forbidden to pour into aluminum radiators and any other aluminum parts. To use this method and compliance with the instructions, you will have to remove the radiator.
The manufacturer of copper radiators has developed a real instruction for washing caustic soda:
- Remove the main radiator.
- Rinse channels with water.
- Blow out with air under pressure is not higher than 1 kgf / cm2 (1 atmosphere).
- Put the rubber tight gloves and the respirator, as such soda corrosive the skin and harm is slightly.
- Of 10% caustic soda to prepare 1 liter of solution.
- Heat the solution up to +90 degrees.
- Pour soda solution into the radiator.
- Wait half an hour.
- Drain liquid.
- Rinse with hot water and blow hot air alternately. Do this many times, about an hour. Produce a process in the direction of the inverse movement.
- Check cold water on the tightness of the radiator.
What means it is undesirable to rinse the cooling system of the engine.
Coca Cola
Many know that Coca-Cola can be removed and clean the radiators. On the Internet there are a lot of video on the use of coca-cola for cleaning teapots and other items, in which deposits are formed.
For flushing radiators and all channels of the engine cooling system, Coca-Cola is possible. Coca-Cola contains orthophosphoric acid, thanks to which rust, oily oils and additives are perfectly removed. But there is one but. The fact is that in addition to an orthophosphoric acid, there are sugar and a lot of carbon dioxide.
If you have chosen the method of washing the cooling system of Coca-Cola, then:
- It is necessary to release carbon dioxide from it.
- Merge the old liquid.
- Pour cool.
- Wait not more than 10 minutes, as it corps plastic and rubber products and surfaces of aluminum parts.
- Drain cola.
- Rinse several times with clean water so that sugar remains in the system. The remaining droplets with sugar when pouring then antifreeze can enter the reaction and the properties of antifreeze will change.
Fairy (Fairi)
Some can use this chemical hemservation for flushing systems of DVSbut not worth it. It perfectly removes fat, but does not dissolve rust and other deposits. But with the help of Fairi, it is possible to wash the radiator outside. For the summer, many flies and other insects stick to the radiator.
Calgon (Kalon)
Funds such as Kalon and others (Mr. Muskul, Tyr), similar to them, are used to protect against science. It is unlikely to remove rust and deposit. Better add it to washing machineSo that the scale does not set out on the drum.
White
Powerful means for removing dirt, microbes, mold with caustic odor. In white, there is sodium hydrochloride, capable of eroding the surface of aluminum parts. When heated whiteness, the aluminum tubes quickly connect. Therefore, you should not use and experience in your experience.
Mole
The cleaner of the mole can be used only in copper main radiators and stove radiators, because there is a caustic soda in its composition. Aluminum surfaces he spoil. He also corps rubber seals, illegones.
After washing, it is necessary to fill a new coolant liquid too, otherwise an air stopper may form. Then you have to drive out this air stop from the system.
Combined method from citric acid, vinegar and soda
There are those who mix different substances in the hope of getting a super remedy for washing the engine cooling system.
Make such a composition of the mixture:
- 50% of soda;
- 25% citric acid;
- 25% vinegar.
Such homemade chemical mixtures can also clean the channels in the system, but at the same time they will destroy rubber seals.
Special fluids for washing the cooling system
Those who are not going to experience drinks as a cleaner, funds from scale, as well folk remedies And does not trust them, they choose auto chemical products.
Auto chemical manufacturers are constantly developing new products, thanks to which the range of choice is great.
Classification of fluids chemical composition:
- Neutral. Neutral are called such that the pH \u003d 7 indicator. You can purchase a PH meter and check what water we drink (useful to drink alkaline water), and so on. Neutral fluids do not have different alkaline and acid impurities. Such fluids themselves cannot well clean the cooling system channels.
- Acid. Such fluids have a pH indicator<7. Хорошо применяются для очищения органических веществ.
- Alkaline. Alkaline PH\u003e 7. Effectively dissolve organic pollution.
- Two-component. In such liquids, acid, and alkaline elements are present. Effectively dissolve and remove scale, rust, various sediments of the result of decay of antifreeze or antiframe.
It is advisable to use only one liquid for chemical composition. Not so, first alkaline, then acidic or, on the contrary.
Among the tops of auto chemicals for flushing the engine cooling system are set as follows:
- Lavr Radiator Flush Classic (Lavra Radiator Fluush Classic) - It chemical from russian manufacturers. Effectively applies to complete the cooling of the cooling system. The cost of the floor of the Laurel Capacity is about 300 rubles.
How to use Lavr:
- Merge coolant.
- Pour two-component laurels. The volume is 430 ml is sufficient.
- Pour water after laurel into the system.
- We launch the engine and let's work at idle for 30 minutes.
- Put and drain the liquid.
- Pour distilled water to flush.
- Run the motor and give to work 15 minutes at idle.
- Merge this liquid and pour new antifreeze or toosol.
After such a cleaning from the system, the deposits of scale, rust and dirt are removed. Pomp and antifreeze will serve longer.
2. Liqui Moly Kuhler-Reiniger (Likui Moli Cachler-Reingener) - remedy for the German chemistry producer for cars. Cost in the area of \u200b\u200b500 rubles for 300 ml of canopy. There are no aggressive substances. 
If you need to wash the radiator channels and the system as a whole from rust and oilphibes, LIQUI is great for this suitable. Does not destroy rubber and plastic products.
To prepare a washing liquid for the cooling system of the car, just one cylinder is 300 ml. 
The procedure for using Liqui Moly:
- Merge part of the old liquid from the system.
- Pour all the contents of the canister directly into the radiator.
- We start the motor and give to work 30 minutes at idle or, you can also ride.
- Drain liquid. Usually the dirty brown liquid is poured.
- Rinse with distilled or boiled water.
- Pour a new antifreeze or toosol.

Output
As you can see, it is possible to effectively make a flushing of the engine cooling system with your own hands, but I recommend using specialty auto chemicals, after reading the instructions. Folk methods can also be effective, but who knows, can for your engine it will not fit.
The engine cooling system allows motor assemblies to maintain a working condition for the maximum amount of time. Drivers are well known that from time to time it is necessary to change antifreeze, which loses its properties in 2-3 years or 30-45 thousand mileage kilometers. Provided not only full replacement Coolant, but also adding it if necessary.
At the same time, even supporting a regular coolant level at the required level, the cooling system may come to disrepair and lead to motor malfunctions. To avoid this, every 2 years experienced car owners are recommended for washing the engine cooling system. This procedure is performed on a paid basis by specialists in the service, but it can be carried out independently. As part of the article, we will explain how to rinse the engine cooling system with your own hands, including without the use of a special fluid.
The engine cooling system consists of a number of elements that must interact competently with each other so that the cooling fluid is supplied to the hottest engine parts during operation. The most vulnerable element of the cooling system is hoses that can clog or break from unnecessary loads.
During the operation of the car under the hood, sand, stones, insects are hipged, dust and other contaminants are formed on the engine. Part of the contamination over time turns out to be in the cooling system, stirring with coolant. This leads to the fact that a scale is formed on various metal elements of the design, which over time is peeled and falls into the hoses. They are clogged, which lowers the efficiency of the cooling system or it dismisses it out.
If on the instrument panel, the problem can be concluded not only in the absence of antifreeze, but also in the problem directly with the cooling system, to solve which will be quite expensive if you need to replace one or more elements. To avoid it, it is recommended to wash the engine cooling system every 2 years.
In car repair services, the engine washing is carried out by special means that you can buy in specialized on consumables For engine stores. There are many similar means, but the most famous laurels and the engine tests. The cost of specialized means for flushing the engine cooling system is extremely high, and many drivers are used to clean the system from outsiders "garbage" by ordinary distilled water. This method is cheaper, but also significantly less effective, since water does not fight with screaming, but only the accumulated microparticles are cleaned.
If there is a question than washing the engine cooling system inexpensively and efficiently, it is possible to use a solution of citric acid or coca-cola. Both fluids are perfectly coping with the task of cleaning from scale and other contaminants of the cooling system.
The process of flushing the cooling system is quite simple, and it consists of the following steps:
Careful flushing of the cooling system is necessary to derive the resulting precipitation, dirt, corrosive elements and harmful impurities that can lead to a violation of the stability of the system. We strongly recommend floating a new antifreeze after washing the cooling system, because in the old liquid, even if the machine passed on it not so much kilometers, there are particles of contamination.
It is no secret that the acidic environment allows you to overcome scale and rust, and it is advisable to use it for cleaning the cooling system. The most accessible opportunity to create an acid medium independently in large volumes is to use a mixture of citric acid and water. The resulting solution allows you to get rid of contamination in the engine cooling system.
Some features of the cooling system of citric acid:
- To create a solution, with severe pollution, it is recommended to use by 10 liters of water 1 kilogram of citric acid. If the pollution of medium gravity, the amount of citric acid per 10 liters can be reduced to 800 grams;
- After the citric acid is filled into the cooling system, you need to drive a few kilometers by car (allow you to work for 10-15 minutes on medium speeds without sharp accelerations), after which leave a tool for another 45 minutes;
- Before pouring a new antifreeze, it is necessary to thoroughly clean the system from lemon acid residues, for this, flushing the cooling system with water is repeated 3-4 times.
Lemonic acid shows itself no worse than many professional tools for cleaning the cooling system.
It has long been known that in everyday life of the Coca-Cola drink can be used as a cleansing agent. The composition of the soda contains various components that allow to clean rust and contamination. Coca-Cola can be used for cleaning the engine cooling system.
Some features of the cooling system of Coca-Cola cooling system:
- The engine operating time on Coca-Cole must be minimal - 4-5 minutes, after which the motor should be turned off and allow another 30-35 minutes to remain in the cooling system;
- Washing with water after Coca-Cola needs to be maintained more carefully than after other means, since the elements of the sugar can settle on the cooling system tubes.
It is worth noting that at the end of cleaning the cooling system from dirt with the use of Coca-Cola, it is recommended after the antifreeze bay to start the engine with an open radiator cover so that the remaining air bubbles come out. Next, turn off the engine and decrease the coolant into the formed additional space.
Few car owners know how to wash the engine cooling system, although in this process it is necessary to take into account the whole mass of the nuances.
Of course, some people do it on their own without having any theoretical knowledge. So you can only harm and disrupt the process of working the cooling system. I will still be sure to consider the question of which fluid for washing the cooling system can be used. Right now you can learn about how is washed automotive system cooling, and what fluids are used for this.
The engine in the process of operation is exposed to large loads, in connection with which it is heated to high temperatures. It turns out that the engine cooling system lowers its temperature. In this system itself, a coolant circulating on special channels is involved. In its physical principle, it serves as a coolant, absorbing heat from the motor. Then the hot liquid is cooled by the radiator, after which the entire heat dissipates in airspace. In the case of the inoperability of the cooling system, the engine in your car will constantly overheat.
Why doesn't she work?
There are a number of reasons why the car cooling system is wrong. Perhaps in the tubes of the radiator and the channels, the tax was formed, which prevents the heat exchange process. It is noteworthy that these precipitates are practically not conducted heat, so it remains inside motor compartmentAnd the radiator will simply work at idle.
In general, the tax is something similar to scale, which is formed as a result of occurring oxidizing processes with support rather than high temperature.
Wash serum
You need washing serum cooling system - this is one of the most best ways. The case is that the serum has a sour Wednesday, in which the whole scale and other raids will quickly dissolve. But there are other reasons bad work Cooling system. For example, in the channels there may be so-called air traffic jam. Liquid will not pass through highways, so in this case It is simply impossible to avoid engine overheating simply.
Also, the inoperability of the fan can cause bad operation of the cooling system, but this is not associated with the so-called channels. But the radiator clogged and garbage can also prevent the proper operation of the cooling system. The heat exchange process is broken, heat is not output from the engine compartment, respectively, the engine itself will be heated until critical temperatures. If you really have at least one of the above problems, then you will definitely need to wash the cooling system
Fluids for washing
If the car is operated in harsh environments, the cooling system can be changed 1 time in two years.
However, it is necessary to remember that before it is necessary to rinse the system to start. How to rinse the car cooling system? For this, there are special chemicals on sale. You can use regular distilled water as a flushing fluid only if the fusion coolant has no precipitation, and also if its normal color is preserved. It is not recommended to use conventional water to flush, as it contains a large number of salts that will accumulate on the main channels.
In general, flushing the cooling system can be practically any liquids having a so-called acidic medium. It is in such conditions that any precipitation will be collapsed. To do this, special chemicals are added to the water. It may even be an ordinary vinegar. You can purchase special additives. Of course, the most effective are specialized liquids for washing the cooling system, which can be purchased at any car store.
Folk ways
Someone fills in their system a regular lemonade "Fantas" or dairy serum - all these products have a sour Wednesday, so any precipitation instantly collapses. Lemonic acid is also one of the best options. In general, all the above listed fluids and products are much more efficient to chemical active substances that are sold in car vehicles, so we suggest you rinse your coolant or lemon acid or whey. We assure you that you do not apply any harm to the car! However, remember that in this case you will need to make the engine re-flushing with distilled water, since some chemicals may remain, which in the process of chemical reaction may well create new precipitation.
Lemon acid
Washing the cooling system of citric acid is one of the best and most common options among motorists. In principle, there is nothing complicated here, all this you can do and your own hands. To begin with, you need to merge the old liquid from the engine cooling system - do not be afraid, just follow the elementary security measures. In no case do not make any action with a heated engine. Along with this, you must know that the coolant contains poisonous substances, so it is best to work in special gloves and glasses.
Next, install your car on flat terrain. Remove the cover expansion tank, I install some capacity for the car, where the old liquid will merge for cooling the engine. Do not forget to unscrew the plug at the radiator below! Then we rearrange the tank and drain the cooling fluid already under the motor itself. Go to the flushing process of the cooling system. Spin absolutely all corks back. Pour the diluted citric acid there. We start the engine and let him work for a while. It is necessary that the entire loop so that the entire contour through the main channels, deleted all sorts of raids there. Then turn off the ignition and give the engine to cool. We repeat the same procedure with citric acid several times.
In general, the number of repetitions above the presented procedure directly depends on what state the fluid will merge into the container. If it does not have any precipitation and kept its normal color, then it means that it is possible to stop, and otherwise you need to repeat the same themes until it is reached required result. Confident that there are in the canals aerial traffic jams? To do this, you need to disconnect the so-called throttle node nozzles - in this way absolutely all air from the system will be removed. Do not forget after washing the cooling system with citric acid to clean from dust and debris of the radiator, as it plays a large role in the engine cooling system.
