Is it necessary to wash the car radiator. How to clean the engine cooling radiator without removing. What can be washed

Correct cargo cooling system from technical support expertsLiqui. Moly.

Spring came and with the first heat to the car cooling system requires already increased attention. Caring for the cooling system is a rule for a competent car owner, and all operations can be performed independently without attracting specialists.

Process use Liqui Moly. Kuhler Aussenreiniger.

Winter in a big city does not pass without a trace for the car as a whole and the cooling system in particular. The main enemy of the cooling radiator is an anti-rolling reagent in half with road mud. This unpleasant substance, falling on the heated cells of the radiator, creates a solid crust that impedes normal heat exchange. As a result, a completely working engine begins to overheat.

So that the engine does not overheat and the radiator did not boil the first thing to be done - clean the outer surface of the radiator. This will help you with the product of Liqui Moly - Kuhler Aussenreiniger.

Kuhler Aussenreiniger radiator cleaner

The composition must be applied to the cells of the cold radiator and give to act within a few minutes. The Kuhler Aussenreiniger cleaner quickly impresses multi-layer dirt deposits and separates it from the surface. A flushing deposit It is important not to use a strong stream of water so as not to damage and do not cut into thin pipes of the radiator.

Need to remember: It is forbidden to wash radiators with devices high pressure!

After using the cleaner leaves a protective film that prevents the rapid oxidation of aluminum and re-contamination. It can also be used to clean absolutely any radiators, intercoolers, air conditioners evaporators, etc.

What to do with small leaks of antifreeze?

When caring for cooling system, on vehicles with mileage, it often happens that after removing contaminants from the radiator, a small leak of antifreeze appears, the radiator starts sweating. This is a sign that corrosion did its job and need to be prepared for replacing the radiator. But with the replacement of the radiator, you can wait. Especially for sealing small damage was created by the Liqui Moly Kuhler-Dichter radiator sealant.

Kuhler-Dichter cooling system sealant

In order for the sealant to work as efficiently as possible, it must be stolen and pour it directly into the radiator under the cold engine (it is assumed that the radiator is not filled with a liquid under the very top).

If there is a lot of antifreeze and for sealant, there is not enough space, part of the antifreeze must be removed from the system, for example, by compressing the radiator hose. Excess one will turn out. Important moment: Antifreeze is an environmentally harmful product, so it is necessary to assemble the part that will turn into a container, or, in the extreme case, a cloth. After filling the sealant, it is necessary to close the radiator cork, turn on the engine and can be seen how to leak disappears literally in front of the eyes. The sealant is especially effective in places where leaks cannot be localized, and antifreeze goes somewhere.

The sealant of the cooling system Liqui Moly works effectively and does not score a cooling system, which confirm the test results of the Autoparad

Such uncomfortable cooling systems need to be done before the summer season.

The operation of the car engine depends on the state of the cooling system, which is largely determined by the quality of the coolant used. Bad products contribute to the appearance of deposits on the walls of the system elements, including radiator. Over time, this layer becomes impressive and leads to a decrease in the passage of the tubes. In some cases, the car radiator partially loses its properties.

When needed flushing

In order to determine that it is time to rinse the radiator, you need to carry out a small diagnosis that is as follows:

• Evaluation of the condition of the coolant;
• Visual inspection of the radiator from the inside;
• Evaluation of the efficiency of the cooling system.

Merging the cooling fluid from the car radiator, you need to pay attention to the content in it sediment, particles and color change. A turbid having particles of incomprehensible substance, the liquid indicates that in the system on the walls, it is likely to have a scale. Although, not always even a clean liquid indicates a good condition of the radiator from the inside.

Note the presence of scale (sediment) visual inspection Radiator. This is done when the plug-in tape is removed using a flashlight. The precipitate has the property of accumulating not only on the walls, but also to a greater extent below. Therefore, the top view will not show the true state of the radiator.

The following indicator of the system clogging from the inside is the frequent turning on the cooling fan. This phenomenon may be associated not only with an increase in ambient air temperature, but also with a decrease in the coolant area of \u200b\u200bthe radiator. When some tubes are clogged, then the liquid through them does not flow and for this reason the speed of cooling the engine of the car is reduced. Thus, the fan is simply forced to turn on more often than usual to prevent temperature excess. It is not easy to notice this if the driver did not pay attention and did not compare the behavior of the fan before and now.

Rinse the car radiator can be without any specifying signs. This is done periodically. Some believe that it is necessary to carry out such procedures every 20,000 km of run. The interval in each case is quite reasonable to appoint himself. If you already had to clean the radiator several times, then guided by the information about interprokraktime, the independent definition of the period of the next cleansing is not difficult.

Funds for washing

Folk Methods

After it is decided to wash the car radiator, you must purchase necessary tool Or use those that are at hand. There are several funds:

• Milk serum;
• Pepsi or Cola;
• Solution of caustic soda;
• Electrolyte;
• Water.

There is an opinion among drivers that dairy serum is capable of qualitatively remove the deposition of the cooling system. It is poured instead of coolant and drive a certain, a few tens of kilometers a distance. After that, the serum is drained from the car, and the radiator is preferably then rinsed with clean water. The process of cleaning occurs due to lactic acid, which is quite safe for system materials.

Recently, a different solution appeared. Instead of brew whey, Pepsi or Coca-Coke are poured. The engine is hardened and give it to work 15 minutes. The procedure is repeated if necessary.

Some recommend rinse the car radiator with a solution of caustic soda. However, the caustic natra is able to remove not only the raid, but also to destroy the metal. Because of this, it is better not to use it as a means for cleaning.

Another means is lemon acid. On the bucket water it is necessary about 50-100 g of substance.

There are those who use the electrolyte from batteries. Much depends on the concentration, but in itself, sulfuric acid is very aggressive. Therefore, it is undesirable to apply it for such purposes, especially, given the material of the pipes.

Most. simple way Rinse the radiator is to use water. Of course, it should be clean before the fill in the system.

Special detergents

Modern auto chemicals are well developed. For a car, you can find on sale almost everything, including a means for washing the radiator.

There are many firms that produce special tools for flushing. The quality of their products is significantly different. Those manufactured by Hi-Gear and Kuhler-Reiniger are considered high-quality goods. For this reason, both prices are more than others. At the same time, it should be recognized that they cope with the task of cleaning very well. Buying cheap items in the store, you risk the health of the car cooling system. The desired cleansing effect in this case is also a great probability not to get, so do not save. Wanting to achieve success in delivering the system from scale, it is necessary to understand that for good quality you have to pay.

In addition to the car for the car there are other used for cleaning household, food capacities, such as teapots. One of them is Antinakipin.

It is possible to extend the time interval between the cleaning of the radiator from the inside, if you pour high-quality cooling fluid into it. Usually, it contains special additives that prevent sediment deposition on the walls of the radiator. In addition, its composition itself prevents education or precipitation.

Do not purchase goods on the road. Despite the relative low cost, they are most likely poor quality, which, in turn, can lead not only to the formation of scale, but also to the destruction of the material of the pipes.

It is better to use that coolant, which is recommended by the car manufacturer.

Well no

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

But to ensure the optimal temperature mode, the cooling system also needs a 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.

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 the pure liquid indicates a good state of the 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 almost with any manipulations with the cooling system, you need to wait for a complete cooling power aggregateOtherwise, it is possible to get unpleasant, and in some cases dangerous burns from the steam bursting through the radiator cover.

2) . The solution is prepared as follows: 100 grams citric acid We divorce with the volume of water that 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

A battery electrolyte can also be used to flush the radiator, 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 many options for special flushing 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 through country roads or by the locality where serious dusting is observed.

The cause of pollution can also be insects falling here during operation vehicle. In the future, they turn into a satisfied solid mass here.

For flushing the radiator outside without removing it, you can use ordinary water, with high pressure washing. This method of cleaning is very effective, but there is negative feedbackwho suggest that a high pressure washing bends the coolant 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 will have to use special tool To clean the radiator outside.

To date, many motorists are very popular chemicals from the following manufacturers:

• Hado;
• Verylube;
• LIQUI MOLY;

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.

Radiator grille - a kind of mud: everything that passes through it, settles on the radiator. And the radiators in the car can be somewhat - at the indemnial cooler (intercooler), steering hydraulic power steering, conditioner capacitor. The radiator of the engine cooling system is always installed last in the direction of the air flow, it means that it is worse than all blown by the incident air flow. And often precisely because of it, water procedures are underdeveloped. After all, other heat exchangers in contamination only partially lose efficiency, and the engine cooling system is more reminded by a two-position toggle switch: "Works normally" and "Karaul, a boiler!".

The engine radiator is contaminated not only outside, rust and scale particles often accumulate in its tanks, as well as aluminum parts oxidation products. And if you thought about washing the radiator outside, it makes sense to combine it with the replacement of the coolant. All cars for the replacement of fluid from all cars are different, but, believe the experience, with a mileage of 80-90 thousand kilometers to update it does not prevent it.

Consider ways of cleaning radiators. We will act, how did the fathers of dialectics bequeathed, from simple to complex.

As easy as pie

The easiest thing is from - they have one radiator. It is possible to rinse it yourself, and not even removing from the car. For example, from the hose in the country. Or bothering the sink. The water pressure should not be powerful so that thin heat sink plates will not be brought. If this happens, the radiator almost ceases to pass through itself air and, accordingly, cannot effectively cool the liquid.

Before water treatments It is advisable to install a plastic film screen behind the radiator: it blocks the way of water and dirt flying on drive belt, generator and candles. At the same time, it is important not to pour the fan electric motor. He is not afraid of splashes, but should not be directed directly on him under pressure.

In company

If the engine cooling radiator is installed in the package with other radiators, its flushing without dismantling is unlikely to give the desired result. The fact is that the jet after washing the first heat exchanger inevitably loses its strength - and the effective cleaning of the second radiator will not work. In this case, you can try to wash radiators from different sides: the condenser - with an outer, and the radiator of the cooling system is internal. But according to the experience I know that there is sometimes something like a felt blanket from a poplar floss between two heat exchangers from a poplar fluff and other materials. Sometimes it is possible to get rid small bloodBy dismantling the radiator grille (on those cars where it is removed separately from the bumper). It will give the opportunity to wash the heat exchangers without. And then, tilting the engine cooling radiator and disconnecting it upper fasteners, Clean the space between the radiators.

The most difficult, but most effective way to clean the engine radiator is to completely dismantle it. To do this, you will have to disconnect and remove the electric fan assembly with the casing, as well as disconnect the heat exchangers of the engine and air conditioning. The conditioner capacitor is more difficult with the condenser: after dismantling, you will have to register the refrigerant system again. Therefore, the capacitor is trying to simply fall aside and flushing, going around without depressurization of the air conditioning system. At the same time, the removal of the engine radiator recommended to be cleaned not only outside, but also inside. For one hundred percent success, it is necessary to drain the cooling fluid from the system and rinse with clean water all the cooling contours. This will increase the efficiency of the heater, since the dirt accumulates in its heat exchanger.

For different machines The cooling system radiator extraction method is different. In most cases, it is necessary to remove front bumper and a radiator grille, as well as dismantle the engine protection or plastic mudguards. Some cars under the bumper there is a beam-amplifier, which is welded to the front ends of the spars, which complicates access to radiators. In others, it can be dismantled, unscrewing only a few bolts, which facilitates access to heat exchangers.

If you do not decide to wash the radiator on your own, you can trust this work by professionals. In this case, the officials will act on the full program - with the removal of the radiator, but the amount will be asked considerable. For example, owner medium-sized crossover in Moscow will have to pay around 12 thousand rubles.

Unofficial services specializing in vehicles of one brand usually evaluate their services somewhat lower. More affordable offers of garage masters, but quality is often appropriate. Wash on the car wash Shot Radiator will cost 100-300 rubles.

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 with such a modern car as 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 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.

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.
