In search of the cause of engine overheating and frequent fan turning on, do not pay attention to the purity of the radiator. Do not forget about the intercooler, the condenser of the air conditioning system of the cabin and the radiator of the automatic transmission, the variator, which are also cooled by the flux air flow. In all systems, dried mud and bent honeycombs will lead to a violation of heat exchange and malfunctions. Solve the overheating problem helps cleaning the radiator. If you go to the case with the mind, you can properly wash the heat exchangers with your own hands.
How often do you need to make cleaning?
Engine cooling radiator, automatic transmission condenser Intercooler is recommended to propagate once every 1-2 years or every 30-50 thousand km. The purification frequency depends on the operating conditions of the car. When driving on dirt roads and frequent, off-road, heat exchanger is needed at least twice as much.
The consequences of ignoring periodic outer cleaning of the radiator:
- power loss on cars with turbocharged. The contaminated intercooler increases the air temperature on the inlet, which is why density is reduced. Less oxygen falls into the cylinders, and due to the larger temperature, the cooling of the walls of the cylinder, the combustion chamber and pistons deteriorate. On gasoline turbocharged FCs, the risk of detonation increases with increasing air temperature in the intakeway;
- air conditioning works badly;
- engine overheating with all the ensuing consequences;
- pinkies, shocks and delays when switching.
Lovers conquer off-road on a car with automatic transmission, the variator follow the purity of the gearbox radiator with special addiction. Often the cause of the jokes, twitching, late switching and accelerated wear of friction packages precisely in overheating of the automatic gearbox.
Is it possible to wash without removing?
Cleaning the radiator outside without removal is ineffective. Dirt, sand and small stones are blocked by the facial part of the heat exchanger, passing the honeycomb in the same way. To push these mud tubes, you need to soften them first, after which it is at the right angle of water under pressure to try to push out. This means that even without removing the radiator from the car you will have to make a minimum to dismantle the bumper, a radiator grille and fans. Without all this, you will not be able to direct the stream of water as perpendicular to the cells as possible, because of what the flushing of the radiator becomes wasted by the time spent. An even more meaningless can be called the purge by compressed air or washing without removal, if the car is installed on the car from the engine radiator, the air conditioner condenser, the intercooler and the oil cooler of the automatic transmission.
Most cars for removing the engine radiator do not need to disassemble the floor of the car. Usually for this there is enough to drain antifreeze, unscrew the engine protected, interfering brackets of attachment of attachments and fastening the radiator itself. There are no problems with the removal of the intercoule. Without removing from the car it makes sense to wash only the air conditioner radiator. And then only if it is not badly polluted, the system is proper and refilled by the refrigerant (to remove the freon condenser you need to pump out that it is impossible to make without equipment).
How to wash it right not to drive honeycombs?
There are several simple rules, the observance of which ensures that the heat exchanger after washing will be clean and will not give to flow.
- Run away the top layer of pollution, flushing the honeycombs of pure water with outdoor and inner. It is necessary to start cleaning from the side directed to the engine. For a few minutes, apply detergent on the cells of the radiator. As a chemistry, it is suitable as a special cleaner for washing the outer part of the radiator from Liqui Moly.And the usual engine cleaner or insect removal means.
All chemicals to prevent negative impact on aluminum should be thoroughly washed clean water.
My radiator is air conditioner
In the air conditioning system, the condenser is necessary for cooling the refrigerant before it gets into the evaporator. If you do not want to pump out freon and re-fill the system, dismantle the fan, the radiator grille, bumper and other items that interfere with access to cells. Soft brush wipe out the outer layer of dust, fluff and dirt. From the inside and external side for 5-10 minutes spray the aerosol cleaner of the engine. Rock the mud pressure of water. Additionally, blow the cells with compressed air and rinse until complete cleaning.
Intercooler
After removal, be sure to check the presence of oil inside the intercooler and in air nozzles. A small amount of motor oil - Norm. But if it is poured out of the intercouler, not only the repair of the turbine is needed, but also cleaning the intercooler inside. With a sink of this kind, a mixture of gasoline and diesel fuel is perfectly coping.
When assembling, pay attention to the fixation of the nozzles. On some cars during re-assembly, it is recommended to change the sealing cuffs. Any leakage of the compressor will result in power loss.
Prevention
The engine overheats if the radiator is scored not only from the outer sides, but also inside. To check, fill it with completely boiling water. Turn the entire area of \u200b\u200bthe heat exchanger with your hand. The presence of cooler sites suggests that the Channel Circulation Circulation Channel is scored inside in these places. Earlier, we considered how to wash the stove radiator and the engine cooling system.
After assembling, fill antifreeze and first launch, make sure that the system has not formed airlock. Warm the car before turning on the fan. If the temperature arrow continues to crawl up, the cabin heater blows with cold air, it is necessary to drive out an air stopper.
Required car quite regularly. This is due to the fact that this design element vehicle Need to maintain the operating temperature of the motor, to protect it from overheating and so on.
In the process of active use, the radiator begins to be clogged with garbage and mud. In this case, the heat emanating from the radiator is not fully transmitted to the environment, but returns back to the engine.
As a result, overheating may occur power aggregate. Clean the car's radiator must be cleaned depending on how much he is clogged. If this is not done, then sooner or later the vehicle fails.
It must be said that the radiator cooling the heater can be clightened, automatic box Car gear, air conditioner evaporator and so on.
The radiator is clogged while using the car due to the fact that dust and garbage fly in anyway. This item is dirty much faster if the vehicle moves through country roads or by the locality where serious dusting is observed.
Insects can also get into the radiator, which in the future, together with dust turn into a rather solid mass.
To clean the radiator without removing it, you can use ordinary water that will clean its outer surface, but often getting to this detail of the car is not too simple.
For the product of high-quality cleaning, the radiator is often removed.
It even happens that the ordinary cleaning with water from the outside is insufficient, since the dirt was so firmly that remove it from the surface with traditional methods does not work.
To get rid of contamination, use a special means for cleaning the radiator of the vehicle outside.
As a rule, the heating radiator or the radiator of the air conditioner is washed with flowing water, but on car washes do it under a rather large pressure. At the same time, the operation must be made as careful as possible, since it is possible to cause damage to the cells, which will simply cause the leakage of the radiator. He will eventually lose his tightness.
In case, simultaneously with the mud to the radiator, salt will sit down, then it should be removed from the surface of the part as quickly as possible. The fact is that the part is made of aluminum, and the saline solution is capable of sneaking it literally in a few minutes. As a result, this will end the same leakage of the car's radiator.
It is also worth noting that the water is unlikely to be able to remove persistent sediments, which means that you have to use a special tool in order to get rid of dirt.
Chemicals designed directly so that the chemical cleaning of the radiator can be produced without removing this part, quite a lot.
Among drivers are widely popular with chemicals produced the following manufacturers:
- Hado;
- Verylube;
- Liqui Moly.
There are also universal cleansing agents that can be cleaned not only the dirt from the radiator of the car cooling system cooling, but also from the entire motor.
The cost of such a substance is the most different - it depends on which company produced this tool. In particular, the cost of one bottle, the volume of which will be about 250 ml, can reach thousands of rubles.
Too cheap means to purchase undesirable, as in low-cost drugs, too active substances can be used, which may be as harmful as pollution itself.
Wash the air conditioner or engine cooling radiator internal combustion It is possible by removing the heat exchanger. If the contamination is not too significant, then you can use the most simple way - blow it with compressed air, and it is done outside the machine, without removing and without turning off the radiator itself.
The sequence of actions here will be next.
- First you need to remove the upper front facing.
- Remove the grille of the radiator, which is fixed in the car on four screws, besides below, it is in addition on three clips. Here you remove the drive of the castle of the hood.
- Now the air intakes are cleaned with a special key, which are located in front of the car, and also remove all plastic elements outside.
- Take the hose, at the end of which the tube should be located, and all the cells of the radiator are blocked out of it, after which they are washed with flowing water.
The car wash will be needed if there is no compressor with compressed air and the device necessary for washing the element. Employees neatly remove the radiator and clean it efficiently from all pollution.
It is worth noting that it is not very undesirable to remove the radiator independently, since it is not too convenient on many cars. It will be very problematic to remove it, and it will be more difficult to return it to his place.
The heating radiator is far from the outside being clogged with mud, it happens that the dust makesys inward. This, in turn, also leads to the overheating of the motor.
So that the heat exchanger is clogged by mud as close as possible, the specialists advise at least once a year to change the coolant.
In addition, it is also desirable to wash the entire system that is produced as Tosol will be muddy.
There are different folk remediesUsed to flush the cooling system: some motorists advise it with a whey, citric acid or electrolyte solution, coca-cola, caustic, and so on. However, all of them are not untested and can lead to the fact that the radiator is fully connected.
The most reliable means to clean cooling system From any kind of pollution, it is washing with clean water.
Technology B. this case It will be next.
- First you need to warm up the motor to the operating temperature.
- All contaminated cooling fluid will need to be completely merged, and this is done both with the radiator and the cylinder block.
- You need to wait a little time to make all this liquid from the glass car.
- All drain plugs return to their places, the system is filled with clean water from the outside and give a motor to work approximately 15 minutes.
- Motor stop and remove water from the system. If it follows the dirty, the operation should be repeated until pure water is returned.
- Now you can pour fresh cooling fluid.
Cleaning radiator outside with special chemicals
On sale today you can find car chemistry of the most different purposes, in particular, there are substances that allow it to be quite effectively rinse the cooling system from the first time. However, it is worth saying that not every means allows you to make it qualitatively. There are substances that seriously violate the work of both the engine and the car as a whole.
In this case, the rule works well - the cheaper the tool, the worse it interacts with the radiator. It is best to use products that offer world-famous enterprises engaged in the release of automotive chemistry, which also managed to conquer a positive reputation.
According to the composition and purpose, these funds are quite different. In particular, some of them are added to the coolant so that they work like the additive and did not allow the formation of scale and rust.
In addition, you can find chemicals that allow you to remove leak tool with nozzles or radiator. However, it should be used as careful as it can, since it is rather viscous and inactive application leads to a clogging of tubes and thin system hoses.
In a row external signs can be determined that the radiator begins to be clogged.
- The fan, the cooling engine, began to run quite often, and he does it not only on idling, but also on the go.
- The motor begins to heat up very quickly. At the same time, when the expansion tank of the heating system opens, the coolant flows out of it.
- The lower part of the radiator together with the lower nozzle has a normal ambient temperature, and the upper hoses belonging to the cooling system are very hot.
- The stove heats the salon very slowly.
Outside, you can clean the design with a special spray. To do this, this substance is sprayed on the radiator grille and leave approximately five minutes.
Take an ordinary garden sprayer and wash off this fluid. It should be done several times up to the moment until the dirt can be squeezed from its surface.
Garden sprayer is used to not damage the cells of the device. They are quite sensitive to different types of loads, therefore, from strong pressure can burst.
Such a sprayer does not create too strong pressure, so it can be safely used.
It is worth noting that the independent cleaning of the radiator is unlikely to help completely get rid of pollution, but it will be able to remove the bulk of the garbage.
This will allow you to continue to go normally and not be afraid of overheating or even complete motor breakdown.
It is difficult to determine which component of the cooling system of the car is the main one, but it is unlikely that anyone will argue that the radiator in this list takes one of the key places. While in the front of the car and cooling out at the expense of the oncoming air flow, it simultaneously collects all the dust and contamination found during the movement.
Internal design also contributes to accumulation in the rust system, scale and other components. Accordingly, first of all, in the event of certain problems with the overheating of the engine, you need cleaning and washing the car radiator, given the factors described above.
To effectively clean the heat exchanger, with their own hands, should be sorted out: in its device and principle of work, possible faults, as and what means and methods it is better to clean the contamination inside and outside.
The principle of the engine cooling system is simple: passing through the cylinder block shirt, coolant, takes out excess heat and under pressure created by pump, enters the radiator operating on the principle of heat exchanger. Here, passing along the core from the top tank in the lower, thanks to blowing the air, the antifreeze cools.
The core of radiators is made from copper or aluminum, depending on their size, it happens in the form of cells, plate or tubular. Between these channels, for which liquid passes, transverse strips are fixed mainly from brass. They repeatedly increase the surface area designed to cool the antifreeze, and also contribute to the attachment of the most stiffness of the entire structure.
For better cooling The engine under certain conditions, for example, with a slow ride, when blowing the heat exchanger is not so intense, there is a fan behind it, which is included in these moments.
Malfunctions radiator
The most common malfunctions of the heat exchanger are:
- Close rust, scale and other garbage inside the core.
- Pollution outside the HOW heat exchanger in Pukhom, etc.
- Driving trash from inside in radiator nozzles.
The following factors will be prompting about the emergence of such faults:
- Frequent inclusion and work on high fan speeds, even when driving at high speed.
- Permanent pulling arrow of the temperature sensor or its readings on the overestimated temperature of the cooling system.
- In the cold period bad heated Salon Auto.
You should not ignore these factors that can lead to overheating of the engine, which is asked not only the sensor, but also torn the lid expansion tank, and clean from the inside or outside the heat exchanger, depending on the type of pollution.
Wash radiator without disassembly
To clean the heat exchanger with their own hands, inside without removal, liquids are used different compositions both manufactured by industry and using sweater.
To clean the car's radiator with your own hands in stores sell funds manufactured specifically for these purposes: 3Ton Super, Step Up, Radiator Flush and others.
Cleaning at home the heat exchanger and the entire cooling system can be made easy lemon Acid And Coca-Cola.
Before the start of the washing with your own hands, you always need to wait for the engine cooling, otherwise there is a risk of burning the ferry, opening the lid of the radiator or the expansion tank.
To clean the radiator inside with citric acid you need:
- Make a solution based on the proportions of 100 grams of citric acid to the amount of liquid (distilled water), which is necessary to fill the engine cooling system.
- Drain, waste liquid and bay, the cooked mixture is required to ride a car for about a week. During this time, interacting with citric acid, all contamination inside the heat exchanger and the cooling system will dissolve.
- At the end of cleaning the drain of this liquid and flushing the entire system from the inside with distilled water, a new antifreeze is poured.
Another head fabric For flushing the radiator, this is Coca-Cola. Cleaning inside the radiator of various deposits of coca-cola occurs due to the composition of orthophosphoric acid. This is done like this:
- Drain of waste cooling fluid You need to fill the entire volume of the Coca-Cola system, before that heated to the carbon dioxide.
- If the pollution is small, then the engine work is enough for 5-10 minutes, when the heat exchanger has not been washed for a long time, then for affective cleaning it is worth riding with Coca-Kolone one day.
- Further, as in all such cases, draining the cleansing fluid, rinse the entire cooling system with distilled water and pour fresh antifreeze.
Outdoor cleansing radiator
During the movement outside the surface of the radiator, there is a lot of dirt: fluff, insect taurus and so on. Shot between honeycombs, they significantly worsen by blowing the heat exchanger.
There are several methods for cleansing the heat exchanger outside without dismantling - water or steam under pressure, but this method is not so effective due to the complexity of access to the surface of the radiator. Therefore, experts advise to purify the heat exchanger with their own hands, after having removed it from the car.
The removed radiator is cleaned from dirt with their own hands using a conventional brush, as well as water and steam.
Correctly flush from the radiator, the dirt is needed with a small pressure, on both sides, so as not to damage the soft surface of the heat exchanger.
For better cleaning, steam will need a steam generator. By treating the grid of the radiator steam, carefully blowing it without deformation and the application of scratches can more effectively clean it from the mud-stuck inside inside.
If there is no possibility to clean the water or ferry pressure radiator outside, then we make this procedure with a conventional brush or the ram. Having lowered the removed heat exchanger into the appropriate capacity, and after having finished pollution by foam, we neatly brushed out all the dirt that clogged between the plates.
Without cooling system, no internal combustion engine can work on the car, and a lot of attention should be paid to its competent functioning. In turn, no cooling system can work without a radiator, which can be safely called its key component.
Each driver should know that there is a radiator in his car, and it is necessary to monitor its cleanliness. The fact is that the radiator consists of numerous vertical plates scored together. There are channels on the plates for which the cooling fluid flows when the engine runs. At the expense of a large area of \u200b\u200bthe radiator, it has time to pass the maximum amount of heat into the atmosphere. Thus, the antifreeze is cooled, and helps him in this opposite air flow when the car and the fan movement.
An important procedure is the washing of the radiator. During the movement of the car in the radiator, various garbage, insects, leaves, sand, details are clogged, insects, leaves, sand road coatRust can be formed on it. The radiator contamination needs to be hampered, and from time to time to clean it or flushing. Washing the car cooling radiator is simple procedureWith which even a novice driver can cope. 
Before proceeding directly to the radiator flushing process, you must make sure that it is required. To determine the degree of radiator contamination, it is necessary to drain the existing coolant and pour water instead (ideally, so that the water is distilled). After that, get the engine and allow it to work for 10-15 minutes so that water "went" by full cycle Cooling, thereby blewing everything too much. When the time comes out, drain the liquid and look at her color. If the fused water is strongly dirty, it is recommended to use special means For flushing the radiator, if not, then cleaning continues with water.
After the first batch of water is merged, fill in the second and, depending on the contamination, add or add a special cleaning agent for radiators. When the fluid is filled, turn on the engine again and allow it to work for 10-15 minutes. How time will come out, drain the liquid.
If you used special tools to increase the effect when washing the car's radiator, before pouring a new cooling fluid, carefully rinse the cooling system with water, you can once again put into the cycle of work for 10-15 minutes clean water to remove all remnants of detergent.
Attention: If the detergent remains in the cooling system, it may cause corrosion.
When the washing of the car's radiator will be completed, fill the new cooling fluid. Please note that some drivers to increase the efficiency of the cooling system and prevent corrosion formation are added to antifreeze when replacing.
Remember that when changing the coolant in the system, an excess air can be formed to be deleted. To pump off the excess air when the antifreeze is replaced, after the cooling fluid is filled, open the radiator cover and turn on the engine. After 5-10 minutes, the air leaves the cooling system and will need an antifreeze top.
How to clean the car radiator from garbage and rust
If the car's radiator is strongly contaminated or rusted, it is necessary to clean it mechanically, that is, to remove and carry out full cleaning. On each car, the radiator is removed in his own way, but it is quite simple to do, and even a novice car enthusiast will cope with such a task.
Clean the radiator with:
- Standard hose through which water under pressure is supplied;
- Specialized minisy.
ATTENTION, if you use a minisku, which has the ability to regulate the water supply speed, then make it as small as possible. If the pressure is strong, the water jet risks the bending cell of the radiator, which will lead to its failure.
In cases where rust began to form on the radiator, various cleaning agents can be used to eliminate it. Note that they are not performed on the basis of aggressive acids that can damage the radiator seals, hoses and other elements.
The automotive engine cooling radiator is designed to maintain the operating temperature, does not allow the motor to overheat and basically copes with its task.
But during the operation of the car, the radiator is littered with mud and garbage, in this case heat from the radiator in environment It is not fully given, the power unit overheating occurs. Cleaning car radiators is required as they are clogged, and if it does not produce it in time, the engine can fail.
Sorious heater cooling radiator can be clogged in the cabin, automatic transmission (if the car is installed automatic transmission), condenser or air conditioner evaporator. Floating RO Box automatic leads to overheating of the gearbox, and the stove scored by mud does not allow heat to pass into the cabin, and in the winter it becomes cold.
During the operation of the car, RO is littered from any garbage and dust flying from the road. Close faster occurs if the car travels on country roads, according to a strongly dusty terrain. Insects are stuffed from the route to the radiator, and the whole litter with time is crushed with dust into a solid mass. 
In order to clean the outside, it is washed with water, cleaning the outer surface. But in place before the heat exchanger sometimes it is difficult to get, and therefore often radiators are removed in order to clean well. Still often the dirt is so firmly settled on the surface of the cooling element, which is not possible to consider it by conventional methods. In this case, special means for cleaning the car radiator come to the rescue.
At all times, RO was washed with running water, cleaning was performed on car wash under pressure. But it is necessary to use a strong water pressure neatly - you can damage the honeycombs, and then the radiator flows, will lose its tightness. If the salt settles the salt, it is necessary to remove it from the surface of the heat exchanger as soon as possible - the salt solution quickly corps aluminum, and the radiator quickly fails. Especially, the water does not wash out resistant sediments, and without chemistry for cleaning it is not necessary.
There are various cleaners of the outer surface of various radiators:
- air conditioner;
- cooling systems;
- Automatic transmission;
- engine oil system.
The market is well known for those cleaners as:
- LIQUI MOLY;
- Hado;
- Lavr;
- Verylube;
There are universal cleaners that can be cleaned not only the cooling radiator or air conditioner, but the engine itself. The price of the cleansing agent may be different, and the products of well-known brands are expensive. For example, a bottle of 250 ml of well-known motorists of the air conditioner cleaner Liqui Moly will cost about 1000 rubles. The universal cleansing agent for Kangaroo Profoam 2000 cars will cost much cheaper - 600 ml, the canopy costs approximately 250 rubles, however, the effect of it is worse than from Liqui Moly.
Recently, pairs are quite common to clean the radiator surfaces, steam, hot ferry radiators are cleaned effectively and quickly, while the automotive chemistry can be practically not used, which in other cases may be harmful to aluminum alloy.
Outer cleaning of the radiator cooling in DVS It is almost always done with the removal of the heat exchanger, but with a slight clogging, it is enough to blow with compressed air, and this can be done without removing the radiator. Consider on the example Ford Focus 2 how you can clean the car's radiator with your own hands on the spot without disconnecting the po:
If there is no compressor with compressed air and tool for flushing, then it will not work without removing radiators without removing, and on Ford Focus 2 remove them quite problematic. It is better to seek help in the car service, professionals will cope with this business without problems.
It does not always pollute the outside, it can also clog mud from the inside, and in this case the motor will also overheat. So that the heat exchanger is clogged with slag as much as possible, it is recommended at least once every two years to fully change the coolant, as Tosol (antifreeze) is flushed with the entire cooling system. Motorists are invented by various folk methods of washing RO - someone recommends flushing the cooling system with brew whey, citric acid or electrolyte, and someone advises rinse the pepsy cola radiator or even caustic. All these ways are dubious, it is likely that after such a wash will have to change the radiator.
The most reliable way is to clean the cooling system with ordinary clean water, flushing in the following way:
There are various auto chemicals on the market, with which the cooling system is washed effectively. But it should be noted that the funds are different, and not everyone benefit the engine and the car as a whole. It works very well here: a cheap remedy - a deplorable result. To wash radiators, use products of well-known brands with a good reputation, and on low price You should not buy.
The most famous manufacturers of sufficient quality auto chemicals are:
- Hi-Gear;
- LIQUI MOLY;
- Lavr;
- Pingo;
The tool is produced different in composition and appointment - some of them are poured as a additive to antifreeze for cleaning the system, others prevent science and rust formation. There are chemistry, with which the toxol leaks from the nozzles and the radiator is eliminated, but it needs to be used carefully, since the pipes and thin hoses of the cooling system can be clogged.
Signs of the clogged cooling radiator
There are signs for which you can understand what RO has been scored:
- the cooling fan began to turn on more often, and not only at idle, but also on the go;
- the engine is quickly heated, Tosol is thrown out of the expansion tank when heated;
- the bottom of the radiator and the lower nozzle is cold, the upper hoses of the cooling system are hot;
- in the cabin car badly warms the stove.
But all the signs testify not only about the scored RO, the cause of overheating can be:
- burned block head gasket;
- defective thermostat;
- incorrectly adjusted ignition;
- restaging the cooling system.
Even if the reason for the overheating of the engine is not detected, still cleaning the radiator will not be superfluous, especially if there are external signs of its clogging:
- outside on RO, dirt is visible;
- tosol in a turbid cooling system, with rust traces.
The condenser in the car is almost always installed in front of the main cooling radiator, so the whole dirt from the road first of all "gets". Sometimes the condenser is clogged so much that it is not possible to wash it and clean it by conventional means. 
With a clogged condenser, the air conditioner does not only work well, but the engine is also overheated. What could be the connection between the cooling system and air conditioning? Everything is simple - the fulfillment of the air conditioner's radiator does not pass the air flow on the PO, and therefore the main radiator is not fully cooled. As a result, the engine itself is overheated.
Remove condense once again It is not necessary - it will have to refuel by freon after cleaning, so cleaning is usually produced in the car. Best tool Liqui Moly is considered on the market for cleaning air conditioners, but the whole problem is to wash the mud. Under a large pressure, the water cannot be supplied, the cells of the condensor will sound, and yet the output from the position is - you can use the Garden Sprayer with a volume of 5-9 liters.
We do as follows:
Fully laundering the air conditioner's radiator is unlikely to succeed, but for the normal functioning of such a cleaning system, and most importantly - the engine will stop overheating with the air conditioner turned on.
- Even if the cooling radiator behaves normally, it is recommended to rinse it at least once every two years.
- Before washing, it is necessary to warm up the engine, and rinse better with warm water - the mud will faster from the system.
- You can not wash or blow radiators under greater pressure - you can easily damage honeycombs.
- Experiment with various means for cleaning are not worth, experiments can lead to RO damage.
- If the cleaning from the inside does not help outside, you need to prepare for buying a new radiator - it is better to spend money on purchasing a new ro, than to repair the engine.
