How to wash the radiator. The means for cleaning the radiator - how to escape from scale? Why do you need to wash the car radiator

29.10.2019

Pollution in the car cooling system can cause engine problems. In this article, we'll figure it out how to wash the radiator (inside and outside) on your own.

The radiator of the car is the first to suffer due to dirt from the road. It especially needs timely flushing inside and outside for normal operation. Dirt, rust, scale, insect corpses - all this accumulates in it. If you do not clean it in time and bring it to a critical state, it will cause the engine overheating even with a non-intensive movement.

When the car began to overheat that cooling system gives failures - The radiator is clogged. For motorists there are 2 ways to solve this problem:

  • buy new radiator. If the state of old terrible, it leaks or detected cracks, almost all honeycombs are scored;
  • Clean the engine cooling system yourself

How to clean inside?

To check the contamination of the coolant, it is necessary to examine it in the expansion tank under the hood. But you can understand anything, because all pollution happens inside - in hoses and connections. Therefore, it is recommended to make flushing. It is recommended once every 5-7 years when changing antifreeze. Tell me how to rinse and how to do it yourself.

First you need to drain the entire antifreeze of the car. If the fluid is clean, then there is no point in flushing - there are no scalp or rust. If there are light pollution, then use distilled water. It does not give a strong flushing effect, but from old sediments will help inside. To do this, pour it into the cooling system, let us work from 10 to 30 minutes, then we drain it and pour a new antifreeze.

If contamination, rust slices are visible in the old coolant, and the color is muddy, then you can use 2 methods.

First - people's way Cleaning the cooling system from pollution at home. Would need packets with lemon acidwhich can be bought at the grocery store. We make a solution with distilled water and citric acid. Suitable 1-2 bags. Too strong solution is not recommended - can suffer rubber parts.

Pour this solution into the engine, let's work for 15-20 minutes. After the wasting engine, we are waiting for 2-3 hours. We drain the fluid and look at its condition. If dirt remained - we do again. This operation is carried out several times until the fluid is clean.


The second way is the use of special auto chemicals. For example, there are special five-minute flushing. Fast and easy. To do this, a special means is added to distilled water. Try not to abuse with its number and follow the instructions on the package - with improper dosage you can harm.
Flushing cooling system
Removes rust, antifreeze decomposition products, scale, sludge. Restores the passability of the radiator tubes and the circulation of antifreeze. Reduces the likelihood of engine overheating when the "plug" appears. Safe for aluminum, steel, plastic, rubber parts.
What chemistry is better to choose? When pollution is large, we choose the most efficient tool that quickly cope with your work. But it is rare. As a rule, the old antifreeze has only turbid color and small contamination. Then it will help "soft flushing". It has a neutral pH, as well as compatible with many antifreeges or antiframes. Therefore, we fill it into the tank under the hood, we go about 1,500 km. During this time, it will wash almost 99 all sediments in the engine. It is the most reliable and the best way Flushing.

After the washing is completed, you should drain the cooling fluid with the cleaning agent and rinse everything with clean distilled water at least 1-2 times. In order to prevent the formation of scale, various additives are added to antifreeze, which due to their anti-corrosion and lubricating elements prevent the formation of rust and various deposits.

How to Clean Outside?

The consequence of the engine overheating of the car becomes clogged outside the radiator (dust or poplar flock). To solve this problem, it is usually blown. It is necessary to remove it from the car and rinse with standard mini-miles (Karcher type preparations) or water under pressure. Try not to overdo it with pressure, because this is it is fraught with damage to the cells of the radiator.

Just water to pour outside the outside, because All major dirt is between cells. To "stagger" need a sink under pressure. It is undesirable when washing a chemical fluid based on aggressive acid components. This can cause significant damage to the entire cooling system, seals or hoses.

The final stage is to replace the coolant with an excess air pumping from the system, which could be formed during the bay of antifreeze. To do this, the radiator cover opens and the engine starts for a few minutes. After the start of operation of the cooling system, air traffic jams will come themselves, it will only be to add antifreeze and close the lid.

The car radiator is intended for one, extremely important function - reduction operating temperature Motor to necessary for the normal functioning of the mark. His work directly affects the operation of the motor, so due attention should be paid to this part. Due to the fact that radiators are peculled during long-term operation, many motorists are faced with the need for such a procedure, like car radiator cleaning. Moreover, it is necessary to clean the radiator not only outside, but also from the inside.

It is worth noting that this process is not so complicated, so you can cope with the problem that has arisen, be it cleaning or washing the radiator, every car owner who wishes to improve technical condition Your car. Another thing, if cleaning no longer helps to solve the problem - in this case it is necessary to resort to repair (soldering, cold welding, argon, and so on), but it is necessary to do it extremely carefully. Remember: if there is at least any doubts about the repair - contact a specialist, because it will be able to protect your car from fatal errors made by you with independent attempts to fix. Repair of the car radiator is the extreme, to resort to which inexperienced drivers are not recommended. But first about washing and cleaning.

Specialists are recommended to periodically clean the radiator. The fact is that the slightest malfunctions in the work of the radiator will lead to overheating of the car engine, which is fraught with fatal consequences. For example, all running parts power aggregate At elevated temperatures are damaged. It threatens to hold overhaul Engine and, as a consequence, significant financial expenses.

Sooner or later, every driver faces

To protect yourself from additional material costs, it is necessary to systematically clean and rinse the radiator.

Important! Cleaning should be performed not only internal, but also the outer part of the radiator.

All about everything you will leave not so much time, but you can completely eliminate the problem insufficient cooling Engine.

Tools and materials

To clean this detail own hands The first thing that will be required of you is free time and, of course, a great desire to do this part of the work itself, without third-party help. Looking in advance, I would like to note that everything will be left for you no more than an hour. And this is taking into account the fact that you will perform this procedure for cleaning for the first time.

One desire will not be enough, you will also need certain materials with instruments, without which you cannot produce high-quality cleaning.

What will take this:

  • from 6 to 8 liters of antifreeze (depending on the characteristics of your model);
  • a little distilled water;
  • special detergent;
  • recreation vessel;
  • rubber or plastic hose for watering;
  • brush (try to choose not tough, but on the contrary, very soft);
  • diluted water with soap;
  • empty bucket;
  • special container for waste;
  • several old rags;
  • a set of tools (screwdriver, keys, etc.).
Security - first of all!

Personal security tools:

  • pair of gloves for work;
  • protective glasses;
  • moisture-resistant form (if any).

Radiator cleaning agents

Rapid development automotive market Safely affected on the appearance of special agents on the shelves, intended for external cleaning of cooling radiators. Their number is growing rapidly, so we will consider only a few manufacturers who are very popular in the modern market.

Popular means for cleaning ro
  1. Hado is a company established in 1991 together by Dutch and Ukrainian experts. For 25 years of work on the market, the company managed to successfully prove himself practically in all CIS countries. The company produces not only cleaning tools, but also various additives for engines that improve their work. Among users of HADO products can be found like positive reviewsSo negative (this happens absolutely with all the goods sold, which is used by good demand). The main advantage of this company is the ideal value for money, which makes products available for each motorist.
  2. Verylube - no less famous brand which, by the way, belongs to the aforementioned HADO company. It is worth noting that the special means for cleaning the engine cooling system can cope with its task in literally in a few minutes (you can learn more in the instructions for the product). The cost of one unit is 250 rubles, it is enough for the full cleaning of the radiator and other elements of the cooling system.
  3. Laurel - known in the territory of the Russian Federation means performing two main tasks. The first is the disposal of the scale and the resulting corrosion. The second is the neutralization of antifreeze decomposition products. This makes the flushing process absolutely safe for all elements of the car. Products of this manufacturer also successfully applied when
  4. Liqui Moly is a wonderful cleaner for external surface cleaning of the radiator surface. It is considered the "king" among such analogues, as it is very effective. The cost of this means is an order of magnitude higher from previous options (from 800 rubles), but the money spent is worth it. There are numerous positive feedback from Liqui Moly product users.

How to clean the radiator from the inside

Before starting work, be sure to make sure the car engine is completely cold. This is envisaged for your safety goals. The fact is that heat The engine increases the fluid pressure. This can lead to unpleasant moments during operation - it's about burns. In addition, the temperature of the flooded fluid is usually much lower on the engine temperature, which may also lead to damage.

In order to avoid mechanical damage to the cooler cells, everything must be observed when cleaning safety regulations. Stick instructions, and everything will be fine.

Getting started

Raising the engine hood, it must be consolidated so that it does not fall on your head when working. All cars are equipped with special fasteners or pneumatic locks, so there will be no problems with this.

Important! The cooler fluid used is a very toxic substance, so when it is removed from the cooling system, you need to be extremely careful. In no case do not merge waste into the ground.

Special container prepared for draining the recycled cooler should not be reused in the kitchen, in contact with food. It is very dangerous to health. When this capacity is selected, some moments should take into account. For example, it should be freely placed between the bottom of the machine and the earth. Also, its width should be large enough to make it easy for washing.

Fitting a suitable container, set it under the cooling radiator, just under the valve.

Remove the cover


We unscrew the cover of the ro.

As mentioned earlier, the temperature of the engine, as well as its type, affects the level of coolant pressure. Necessary information You can read on the cooling radiator cover (PO). To preserve the required pressure in the radiator, the lid is equipped with a special spring. If you notice that it (spring) lost in stiffness, then it must be replaced. Also, the replacement is required if rust has been formed on the mounting places.

It is worth noting that there are different types covers, each of which is intended for a certain level of pressure.

Diagnosis of clips and hoses

Two hoses are attached to the radiator: the first, attached to the lid, plays the role of the output of the accumulated hot liquid from the car engine. The second hose is attached at the bottom, it serves to supply the cooled liquid to the engine. To replace the hoses, it will be necessary to first dry the radiator, after which it is necessary to diagnose the presence of faults. If there are even minor cracks or leaks on the hoses, they must be replaced. The same applies to metal clamps, replaced which is also necessary in the presence of rust traces.


Check the quality of all hoses and clamps

The replacement of hoses also need to be carried out if they lost their former strength and become soft. It is advisable to replace both hoses immediately - so more reliable.

Getting rid of coolant

Due to the toxicity of the cooler, be sure to wear working gloves before unscrew the valve. Preliminate the cutting vessel under the car in which all liquid should drag. When all the residues of the coolant found themselves in the tank, the valve can be spinned back. Waste place in a specially prepared container.


Cooling fluid necessarily need to merge into a special vessel

The flushing of the radiator implies another liquid container installed under the valve. During the execution of all operations, it is not recommended to remove protective gloves.

Flushing radiator

This stage of cleaning the radiator can be called the easiest performed. Using a plain garden hose, fill the radiator with clean water. Then water should be merged into a special container for waste disposal. Pay attention to the color of water flowing from the radiator: if it is still dirty, then this procedure must be repeated again.

Washing with conventional water from under the tap can only be done if the inner part of the radiator is not dirty too much. Otherwise, it makes sense to take advantage of a special tool for cleaning. What kind of tool choose is your business, most importantly, so that it coped well with its task.


For flushing PO fit the usual water from the hose

Bay cleaning fluid into the radiator, get a car for about 15 minutes. Time should be enough to distribute the funds in all the "catches" of the cooling system of your car. After a 15-minute operation, the cooling system must be cleared. For this purpose, use water (back back to the garden hose).

Perform cleaning is necessary when the engine is running. Also remember to open special cranes for draining liquid.

Cooling fluid replacement

Quality coolant (coolant) consists of only two elements - this is water and antifreeze. Moreover, ordinary water from under the crane is no longer rolled, you need to use distilled. This is due to the fact that the composition of distilled water does not include various mineral substances, due to which the chemical properties of the coolant may change. In this case, the liquid will cease to perform its original task, and the engine will overheat very quickly.

For cooking, you need to mix these two components in a clean container. Of course, you can buy a ready-made liquid at any auto parts store. A good option is AUTOMAX (AUTOMAX) or ELF, Although you can choose any other option.


Now we produce replacement of coolant

The average cooling radiator is able to accommodate approximately 6-8 liters, which must be considered in advance when you purchase or interfere with it yourself. Agree, it will be unpleasant when you have to go to the store for liquid, while the process of cleaning the radiator almost ended. Initially, think over all the details of your plan.

We remove air from the system

Air traffic jams formed in the sockets and highways of the cooling system must be removed. Before proceeding with the removal of air, the engine must be warm well. Opening the radiator, run the engine and let it work on the minimum turnover about 15 minutes. Open RO will reduce the pressure level slightly.


How to remove air from

After 15 minutes of work, turn on the heater in the machine (stove) on full power. Thanks to the inclusive stove, the coolant will be able to circulate freely through the system, and the air copied in it will gradually go through its neck. After the whole air leaves the system, you need to fill the released cooler.

Important! By adding the cooler, you need to be careful, since very hot air can still go out of the neck - you can burn.

Topping the required amount of cooler, tightly tighten the lid and wipe the neck with a dry ringe.

Final cleaning

Making flushing, make sure that there are no possible leaks on the radiator. Also, pay attention to the valve: Does not splash there. If you use strong chemicals for cleaning RO, try to delete their residues from the case upon completion of the procedure. Otherwise, the formation of corrosion is possible, which has a detrimental effect on the details. But this does not concern antifreeze, all motorists know about whose anti-corrosion properties. Ethylene glycol in it prevents the appearance of scale and corrosion.

Outer cleaning of the radiator

Mud accumulations on the outer part of PO often can cause frequent engine overheating. It is possible that after the opening of the hood you will see a layer of dust or fluff with a thickness of several centimeters. Many drivers solve this problem using a sprayed air radiator. The method is effective, but you need to be extremely neat. You do not want to overdo it with pressure and mute radiator cells.

Many experts recommend a reliable Dedovsky way - wash radiator with water with soap. Using a nylon brush, try to scrape as much dirt as possible from the surface of the part. The direction of movements of the brush must coincide with the location of the cell. Otherwise, the risk of damage to the fragile metal product.

An example of an old good grandfather's way

Dirt remnants. Rock with a powerful purest water rod - it will help clean the rook quickly and efficiently. Repeat such a procedure is recommended regularly, every 18-20 thousand kilometers passed.

Tip! Try to avoid different types of aggressive acids, since the use of chemical compositions based on them can cause serious damage to the details of the cooling system of your car.

Summing up

Conducting regular flushing and cleaning RO, you can not only improve the overall condition of your vehicle, but also to extend the life of the radiator. The procedure is simple, but if you still have problems, then it is better to immediately seek help from specialists. The cost of their services is not very big to risk your favorite car. Not a nail or rod, dear motorists!

The cooling system should ensure the automatic maintenance of the optimal thermal mode of the engine on all speed and load modes of its operation at ambient air temperature -45 ... + 45 ° C, fast warming Engine to operating temperature, minimum power consumption for the actuation of system aggregates and operational reliability determined by the service life.

But to ensure optimal temperature mode The cooling system also needs periodic flushing. This is the same necessary procedure as, for example, the replacement of oil and filters.

If the engine cooling system during the replacement of the coolant does not rinse, then scale and dirt accumulated inside will scream thin channels of the radiator, nozzles, pumps, which, in the end, will lead to deposits.

The content of the article:

When does the cooling radiator need flushing?

Explicit signs that the cooling system needs cleaning:

  • the cooling fan is turned on more often, and not only on idling, but also on the go;
  • the engine is quickly heated;
  • of expansion tank When heated, Tosol is thrown out;
  • the bottom of the radiator and the lower nozzle is cold, the upper hoses of the cooling system are hot;
  • in the cabin of the car heats the stove badly;

Over time, the cooling system is settled. Merging the cooling fluid from the radiator, pay attention to the content of precipitation, particles and color change.

Middle, having particles of incomprehensible substance liquid, indicates that in the system on the walls probably there is a scale. Although not always, even pure liquid indicates good condition Radiator from the inside.

A sealant can also get into the coolant, with which small cracks and holes are rushed. Maybe also getting oil.

Types of cooling system cooling

Cleaning the car cooling system is divided into internal and outdoor work.

Internal work. Internal cleaning lies in the elimination of corrosion traces, residues motor oil, coolant (Tosol or antifreeze), as well as scheduling.

Outdoor work. They are in the external wash of all components of the cooling system. That is, we wash off dust, dirt, sand, etc. Also, carefully from the cooler of the radiator, it is necessary to wash insects sticking on it.

How and what to rinse the radiator inside?

To wash the radiator from the inside, you can use one of the following tools:

  • Citric acid;
  • Pepsi or cola;
  • Electrolyte;
  • Distilled water;
  • Ready drugs;

Let's talk about each of these ways more more than more.

Wash radiator cooling with citric acid

1) . As in general, and in almost any manipulations with the cooling system, it is necessary to wait for a complete cooling of the power unit, otherwise it is possible to obtain unpleasant, and in some cases dangerous burns from steam from the radiator cover.

2) . The solution is prepare as follows: 100 grams of citric acid are divorced with the volume of water, which is enough to fill the engine cooling system.

3) . Next, we need to drain the spent fluid, and instead of pouring the prepared composition. We ride a car about a week. During this time, with acid interaction to dissolve all pollution inside the cooling system and heat exchanger.

4) . After a week, the fluid with an acid must be drained, and washed from the inside from the inside with distilled water, then poured to the Tosol or antifreeze cooling system.

Washing radiator cooling cola (or pepsy)

1) . From the cooling system, we drain the whole liquid, and fill the Coca here - the cola, before that he was heated so that carbon dioxide does not come out of it.

2) . If the nature of the deposits is not critical, it will be enough if the engine works for 5-10 minutes. But in cases where the contamination is very strongly aggravated by the system, it is necessary to ride during the day.

3) . Then the cola merge, was rinsed with distilled water, after which they pour fresh cooling fluid.

Electrolite cooling radiator flushing

To wash the radiator can also be used battery electrolyte, with a density of 1.27.

1) . In a large 10-liter bucket, mix clean water with a liter of this substance, then the resulting solution is poured into the cooling system.

2) . All trips on this day must be performed with a filled radiator, which will make it possible to clean it as much as possible.

3) . In the evening, the solution merge and rinse with a radiator with clean water, after which we pour the cooling fluid.

Attention! This method personally did not use, but according to reviews on the Internet, the electrolyte is also effective tool To clean the radiator.

Distilled water radiator flushing

If you have not noticed any special contaminants when replacing the coolant, it is possible to do with distilled water. Use tap water with lots of salts and impurities is not recommended. As an example, you can take a kettle, which, after using tap water, it appears.

1) . Clean water pour into the radiator and launch the car at idle.

2) . After 20 minutes after work in this mode, the water drain and pour the coolant liquid.

Ready drugs

To date, you can find a lot of special options. washing fluids. They can be both alkaline and acidic. They are best used in accordance with the instructions.

How and what to rinse the radiator outside?

The reason for the contamination of the radiator outside can become dust and garbage. This item is dirty much faster if the vehicle moves along country roads Or in the area where serious dusting is observed.

The cause of contamination can also become insects that come here during the operation of the vehicle. In the future, they turn into a satisfied solid mass here.

To wash the radiator outside without removing it, you can use conventional water, with a sink high pressure. Such a cleaning method is very effective, but there are negative feedback, which suggests that the high pressure washing bends the cells of the radiator. In fact, you just need to learn how to use the sink.

For example, to safely wash the radiator, it is enough to use "Vario" as the nozzle, and not "milling". The turnover can be used to maximize, but is not focused, but at a distance of 30-50cm from the radiator. In addition, the angle should be straight or close to it.

I would also like to note that to get to some areas of the radiator, not so simple, and therefore, with sufficiently strong pollution, it is still recommended to remove it.

It happens that the dirt on the radiator meets so firmly that it is very difficult to rinse it with usual water. In this case, you will have to use a special means for cleaning the radiator outside.

To date, many car enthusiasts are very popular with chemicals from the following manufacturers:

  • Hado;
  • Verylube;
  • LIQUI MOLY;

Video

1) . The cooling radiator washing is recommended at least 1 to 2 years. And it is even in that cases if the cooling system works normally.

2) . If the inner and outdoor cleaning did not help solve the problem, it is better to still buy a new radiator, as it will cost you much cheaper than the repair of the engine.

Conclusion

As you can see, there is nothing complicated in the washing of the radiator. Anyone can cope with this. But due to periodic flushing, you can not only extend the life of its service, but also ensure the normal operation of the engine.

As you know, a lot of heat is highlighted when the engine is running. Part of the energy is converted into the torque, and the part goes on the walls of the cylinders and the block. To work in normal mode, it provides cooling channels. Inside the use of a special coolant. It can be Tosol or antifreeze. Liquid, moving along the engine channels, heated. The antifreeze flow falls into the radiator. There, the liquid is cooled and circulates back to the unit. But what if the system does not cope with its task? Cleaning the cooling radiator. We will talk about this in our current article.

Types of operations

Distinguish several types of washing:

  • external;
  • internal.

Experts are recommended to produce flushing "in the complex". Only so you can provide the perfect purity of the cooling radiator. After all, the heat exchanger assumes the entire dust blow, because it is immediately behind the grille. Also in his cells are insects, poplar fluff and other items. All this negatively affects warmth. Internal cleaning of the radiator is equally important. After all, fluid over time loses its properties and falls into the sediment. If on the walls it forms a scale. Below we will look at how the radiator is cleaned inside and outside.

Inner flushing: Does she need?

Often, car owners do not pay attention to this procedure, and in vain. After all, this operation may be needed even modern carlike Ford Focus. Cleaning the radiator inside allows you to remove scale and promotes better heat exchange.

But before proceeding to the procedure, you need to merge the old liquid. If it does not have a rusty color, it means that you do not need the cleaning of the radiator. Ford Focus in this case will work further without interruptions. But if antifreeze has a brownish shade, things are bad. This means that the fluid has lost the anti-corrosion properties (additives are added to the composition of production) and no longer performs its main function - heat sink.

Cleaning the radiator inside with his own hands

So, we merged dirty antifreeze. What should I do next? The essence of washing is quite simple - you need to make a work on a third-minute fluid to work for several minutes. And so until the scale and rust are completely deleted in the system. You can use conventional distilled water as a liquid.

Note!Use for internal washing water from under the tap is strictly prohibited. It can allocate scale and provoke internal corrosion.

Recently, motorists buy specialized means for cleaning the car radiator. These drugs are mixed with distilled water in a certain proportion and aggressively act on scale. As a result, after a short operation of the engine from the radiator, all accumulated inside dirt was washed.

Be careful!Do not abuse the number of cleaning agents. This can harm the engine cooling system. It is better to repeat the same procedure several times, with an absolute amount of acid substance.

After the procedure is completed, the mixture is removed and poured pure distilled water. It will finally wash the residues of the acid substance. At the final stage, a new concentrated antifreeze is poured into the tank.

External cleaning of the radiator with their own hands

Every year, motorists face such a problem as a poplar fluff. He is mercilessly scoring the cells of the radiator. As a result, the liquid inside is not cooled fully. The engine operates in the break mode, which is not good for the block and the GBC. In addition, insects fall on honeycombs. Especially often those who go to long distances are facing. Insects literally dug inside the hundred, get them from there very hard. But whatever pollution from the radiator, the washing will help to correct the situation. It is best to do this with a mini-washing, under pressure.

Note! Coolant of the radiator (and both aluminum and copper) have a small thickness, in view of which are very fragile. In order not to damage them, choose the optimal pressure on the mini sink.

Specialists do not recommend using chemicals based on aggressive components. It can harm both the mini-sink and hoses on the radiator. Wash the outer part of the heat exchanger is needed under a slight pressure of water, without chemical additives.

Alternative method of external cleaning of the radiator

Alternatively, you can use the production of the heat exchanger. In this case, not water plays the role of the cleaner, but compressed air. The method is quite effective and does not harm the radiator. The only drawback is a need for a powerful compressor. This is not far from every motorist. A heat exchanger from the rear is blown. Thus, you can blow all the dust and insects that hit the front side of the element.

About additives in antifreeze

Unfair manufacturers are diligently trying to "fall" by the car owner any unnecessary product. What you just do not meet on the shelves of automotive stores ... For example, additives in antifreeze.

Why not buy them? Any normal coolant producer already at the production stage adds all the necessary lubricants and anti-corrosion additives. You should not go on someone else's occasion - just change the coolant on time and sometimes wash the radiator.

Conclusion

So, we found out how to clean the radiator yourself. Washing heat exchanger is a very important prophylactic measure that will avoid unauthorized overheating of the power unit.

The operational parameters of the auto depend not only on the state of its power unit and the chassis, but also the efficiency of the cooling system. To a certain extent, this is ensured by using high-quality cooling fluids. Otherwise, in the inner walls of the heat exchanger, deposits quickly appear, which entails the loss of its heat-conducting properties.

When should I do flushing?

Before cleaning the car radiator, a simple inspection should be conducted, which will allow to assess its degree of contamination:

  • Evaluation of the efficient cooling system.
  • Checking the condition of the coolant (coolant).
  • Inspection of the inner part of the heat exchanger.

The first thing that owes a car owner is a frequent inclusion of the forced cooling fan. The reason is the reduction of the cooling area, the fluid flow is reduced due to the fact that radiator tubes are clogged with outsiders. It is also possible to clog the outer plates with dust or insects.

During drain, the coolant must pay attention to the presence of foreign inclusions in it, as well as to change its color. About scale on the walls of the radiator node testifies the sediment or small particles.

The visual inspection of the inner part of the heat exchanger also allows you to determine the presence of scale. It is performed using an electric lamp when the neck stopped. However, this method can hardly be called efficient, because the precipitate is more accumulated at the bottom. Therefore, any motorist interested in the question, as and when to clean the car's radiator, should understand that the top of the top will not reveal the true state of the aggregate.

Experienced car owners are washed with a heat exchanger even in the absence of listed features. The procedure is carried out on average with a frequency every 20 thousand km of run, but the interval can be shifted depending on the quality of the coolant. If you already had to clean the radiator node several times, then the schedule of work will not work.

Make yourself: how to clean the contaminated car radiator from the inside?

If you perform forest cleaning The heat exchanger can be directly by car without resorting to its dismantling, then for the inner washing it is necessary. The removal process is accompanied by the execution of the following items:

  • Under the radiator valve, install a suitable container.
  • Unscrew the throat lid.
  • Release the valve on the cylinder block and drain the coolant.

To clear the insides of the heat exchanger, you need to send a dense stream of water in its neck. All extraneous particles and precipitate will go through the lower nozzles. The procedure should be repeated several times. In case of severe pollution, the use of special cleaning fluids is permissible.

After flushing and installing the radiator, you need to get rid of air traffic jams in the system. To do this, you should start the motor and give it to work about 15 minutes with an open neck heat exchanger, then turn on the heater to the maximum. A simpler way implies the installation of the front wheels of the car on the elevation with the subsequent engine start for 2-3 minutes.

What means are used for cleaning?

Auto chemical manufacturers have mastered a fairly wide range of car care products. Many firms offer special means to clean the radiator assembling system. Quality is distinguished by products under stamps:

  1. Liqui Moly.
  2. Hi-Gear.
  3. Kuhler-Reiniger.

The price of these products is quite high, but the effect of their use will cover all the wretches. For those who still do not know how to properly clean the radiator of their car, it should be noted that inexpensive drugs are not only well coped with the task, but they can harm the heat exchanger. As an alternative, some use the domestic product Anti-Nakipin.

Folk remedies

Folk crafts claim that they managed to achieve a positive result without special costs with the help of available funds:

  1. Pepsi Cola.
  2. Dairy serum.
  3. The solution of caustic natra.
  4. Weak electrolyte solution.

The use of serum is practiced by drivers since the absence of auto chemicals. It is poured into the radiator and pass about 20-30 km, after which the solution is merged, and the insides are washed with water. With the advent of Coca-Cola, the craftsmen involved in the process and this product. It is poured and allowed to work the engine for 15 minutes.

The expediency of the use of caustic soda causes some doubts, since its elements are capable not only to remove the flare, but also to destroy metal parts. The same attitude of the specialists also causes the use of electrolyte, whose nature is too aggressive and is able to harm rubber products.

Lemon acid as a means is suitable to a greater extent, it is necessary for the water bucket of it 60-100 g. These alternative substances are eliminated from the need for dismantling work, but the products of their activities in the form of individual particles may prevent the thermostat functioning.
