How to wash the radiator on the car. Cleaning the radiator - Synonym for stable operation of the car engine: guide for dummies. A few words about the radiator device

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 enough to merge antifreeze, unscrew the protection of the engine, interfering attachment brackets hinged equipment 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 rulesThe observance of which guarantees that the heat exchanger after the 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.

Everything chemicals To prevent negative impact on aluminum should be thoroughly washed with 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 the assembly, the fill of antifreeze and the first launch, make sure that the system did not form an air traffic jam. 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.

It is difficult to determine which component of the cooling system of the car is the main one, but hardly anyone will argue that the engine cooling radiator in this list takes one of the key seats.

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. Interior 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 cleaner and washing the car radiator. To effectively clean the heat exchanger, it should be understood in its device and the principle of operation, possible faults, as and what means and methods it is better to clean the contamination inside and outside.

Principle of operation

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 journey arrows temperature sensor or its testimony 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 inside without removal, liquids are used for various 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 the heat exchanger and the entire cooling system can be carried out at home simple lemon Acid And Coca-Cola. Before you start, you need to wait for the engine cooling, otherwise there is a risk of burning the ferry, opening the radiator lid or the expansion tank.

To clean the radiator lemon acid you need:

• Make a solution based on proportions: 100 grams of citric acid to the amount of liquid (distilled water), which is necessary to fill the engine cooling system.
• Drain of waste liquid and bay prepared mixture, it 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, draining 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 coca-cola radiator 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, it is necessary to drain Coca-Cola, rinse the entire cooling system with distilled water and pour fresh antifreeze.

The principal design of cars has not changed more than a hundred years. Therefore, a car on the engine internal combustion Until now, an effective cooling system is required. Moreover, every year, it should become more and more efficient and more reliable than the higher technological complexity. power aggregate, the more critical to the observance of the temperature mode of its work.

At the same time, no cooling system can do without a radiator in which the fluid is cooling the entire system. The cooling system radiator is a key element providing a stable car operation. Therefore, maintaining the purity of this unit is to preserve the stability of the entire car.

Moreover, the radiator can be dirty outside and inside. With internal contamination, the bandwidth of the radiator decreases, and the coolant does not have time to cool to the required temperature. Because of this, the car engine can overheat or work in a slightly elevated temperature mode, which contributes to the rapid wear of the elements.

The need for cleaning occurs due to the very design of the radiator. It consists of a set of plates made of metal material (more often than aluminum or its alloys), located very close to each other. In the plates themselves there are small channels for which the heated liquid moves. At the same time, cooled by a large area of \u200b\u200bheat exchange of the entire design of the radiator, coolant, coolant.

Therefore, the efficiency of the radiator is very important to maintain a constant temperature regime. power plant. But, the radiator located is an open oncoming flow of not only air, but also dirt, midges and pebbles. Thus, scoring a small-scale structure and preventing effective heat exchange with the atmosphere.

It should be carefully preventing such pollution and periodically clean the important element of the cooling system. Do not be afraid of this procedure, even a novice car owner can easily cope with the work.

How to wash the radiator

After the draining of the test of water, it is worth pouring the system again, but with the addition of cleansing additives. And repeat the washing cycle with a running engine of at least 20 minutes. And then it is worth again to repeat the procedure with clean water without additives. This is done to leash out possible remnants of cleaning agents that aggressively act on rubber products and can cause metal corrosion. The system rinsing is also carried out for 20 minutes.

After all the cycles of thorough flushing of the radiator of your car, you can fill a fresh batch of coolant. But it is worth remembering that when filling out the system, a "air" cork may form. Which will not allow normal circulating fluids in the system. To remove excess air, you need to leave the car engine in the started state and open the radiator lid. At the same time, it is necessary to monitor the level of toosol and periodically add it to the system.

How to clean the radiator from dirt and dust

Separately, it is worth noting that the use of minimiles with a high pressure of the exiting water jet - can lead to a radiator breakage, with inaccurated circulation. The fact is that the cells of the radiator are made of a thin sheet of metal that are easy to be laughing.

At this stage, it is important to remove the bulk of pollution from large fractions that interfere with the normal circulation of the air flow. In bringing to the factory purity of the radiator - there is no need.

But it is worth paying attention to possible foci of corrosion, which should be eliminated using special means that do not contain aggressive acids and solvents. Powerful substances are able to harm rubber and plastic elements of the radiator.

As a result, you will get a clean radiator working with the effectiveness of the new one. This procedure is recommended at least once every two years.

The performance of the car depends on very minor things. Due to the leaky rubber pipes, part of the antifreeze can find out of the cooling system, and unnoticed overheating will be wrapped with colossal repairs. But even with a fully serviceable technique, the car's engine will be waiting for very strange collisions. The radiator is clogged with mud and stops performing its functions.

Dirt and salt

Before you take for an expensive washing, it is better to make sure of its need to thoroughly. If the cooling fan often bursts under the hood, and this is no reason to look at the radiator with a flashlight. Pollution is visible to the naked eye. Between Sot, dried insects, needles, blades and winter salt were clogged. In the worst case, there is just a crust of a gray solid substance, impenetrable for air flows.

"There are two most optimal periods per year for a radiator washing procedure. This is April and July, "says technical expert Carfix Oleg Chirkov. In summer, cooling cells are clogged down by the poplar and sticky kidneys. Under the action of temperature, they are compacted and penetrate deep into the cells, where they sin in a dense mass together with dust. Air flows cannot break through such a pillow, and the cooling process of the motor is broken. But the saddest thing is when a winter dirt is superimposed on a fat poplar fluff with salt.

Usually takes several years before the new radiator is experiencing a deficit of heat transfer. In some southern cities with multiple dust, the contamination process is delayed by 7 years or more. In Moscow, with an abundance of winter salts and chemical reagents - a little less. Cars risks risks for long-distance trails to the risk group. The speed is large, the spread energy with dust particles is large, the dirt deeply dugs into the honeycomb.

Large problems expect those cars who hold on the dustless wagons. Not only, from under the wheels, stones fly in a glass, so the rising dust clubs are scored not only the radiator, but also all filters. In winter, an emulsion from water, sand and dissolved chemical reagents flies. This substance listens to the radiator and literally cements the space between the cells. Under the action of the Temperature of the Zhijokokoku in solid crust. And here you should not be deceived: she herself will never fall off, careful cleaning is required.

Water is dangerous

The problem is that the radiator washing is a complex technological process. Few people know that there is not one in the car, but several radiators. In addition to the major front, there is auxiliary, there is also an oil radiator and cooler automatic box Transmissions. They are deployed to incoming air flow and mounted in the depths of the engine compartment. It is hidden radiators often and are in the polluted state and are the cause of engine overheating and transmission. It is impossible to get to them without disassembling some removable parts front. This is usually a bumper, grille and other mounting devices.

Next, the most difficult thing is to: so wash the radiators so that the car does not get on the joke. Some mosters simply take "Karcher" and run a jet under pressure in 150 bar in motor compartment. Often such things are embarrassed on ordinary washers by chance hired employees. For modern car This barbaric death procedure is similar. Electronics fails, the interruptions of sensors and sensors begin. The onboard system issues errors. And these are the most harmless of the misfortune. Much worse if the jet hit the black box at the radiator hiding in itself the engine control unit. Then writing disappeared, the repair will cost several tens of thousand rubles.

In general, the radiator washing at the modern "seven-year" is a complex technical process that has a pre-prescribed algorithm of actions. Machine must make a master of certified car services, familiar with technology and having tolerance.

Meanwhile, radiators are often clean by the owners independently in the garages. It concerns this mostly very old machines without complex electronics and with uncomplicated engine cooling systems. Antifreeze is pre-drained, disconnect rubber cuttings and pull out the radiator from the car. Then it is put on bricks, "Karcher" is taken, and the jet of water is shed dirt. But here it is necessary to be neat, because high pressure Waters can damage honeycombs. Water in limited spaces repeatedly increases the initial pressure, on which the entire hydraulics is built. The cells are deformed and under the action of lambed dirt can be prolonged. In general, the pressure is better twisted to a minimum, and the radiator is pre-treated with chemical preparations for better peeling. Repeat the procedure is necessary depending on the degree of pollution.

Many often forget that in addition to oil in the engine and various filters there are still cooling system, which also needs to be regularly serviced to the engine vehicle He worked properly and as long as possible. But unlike the same engine, gearbox and other mechanical parts in the machine, this cooling system actually does not make any extraneous sounds. If there is no coolant temperature sensor, then you really did not know what actually happens inside the cooling system.

Cooling the car engine is carried out precisely using a radiator that acts as a regular heat exchanger placed in a machine to a specific area (place) where large air flows pass. That is why the cooling radiator plays a very important role in the work of the entire car cooling system. Well, how to be, if you were driven from within various saline and other sediments? Do I need to wash it? And what will happen if you do not follow the state of the car radiator? We invite you to get comprehensive answers in our article.

As we have already told above, the cooling radiator with the help of heat exchange cools the heated antifreeze, which circulates along the cooling system. It also heats away from the engine due to the same heat exchange. As a result of this process, the engine temperature decreases. As you understand or already know that for efficient engine cooling, this antifreeze circulates by big circlepassing naturally through the radiator.

The circulation of coolant is watched by a water pump ( water pump), which rotates due to the torque of the resulting belt from the pulley, fixed on the front of the engine crankshaft.

Due to this, the water pump begins to swing the coolant faster as soon as the engine turns begin to grow. As a result, the larger the load on the motor, the faster it circulates the antifreeze on the cooling system, which makes it possible to prevent engine overheating.

In the engine cylinder block and in the radiator there are metals and various alloys, where, as a result of the process, their coolant (antifreeze), which has an aqueous base and leads to a chemical reaction between them. As a result, unwanted deposits are formed in the cooling system. Therefore, if you do not serve the cooling system, it will definitely lead to serious consequences and problems with the car.

Cooling radiators in their design have horizontal plates inside which the antifreeze circulates (coolant).

Thanks to these plates, heat exchange is carried out. It is through these plates and pass the flow of cooled air that takes the heat that transfers the heated antifreeze to the plates.

Also, this antifreeze due to the content of water in it sooner or later leads to rust radiator corrosion) from the inside. That is why it is recommended to change antifreeze in the cooling system every two or three years, It all depends on the mode of using your car.

Including, even in the absence of such rust in the radiator, as a result of the chemical interaction of antifreeze with metals in the cooling system, internal passages in the radiator itself can be clogged, where the main heat exchange processes occur.

The increase in these deposits creates a thermal-non-conductive layer inside the radiator tubes and lines for which antifreeze circulates. As a result, the thermodynamic efficacy of the entire cooling system is hampered.

The goal of the cooling system is to release as much over heat from the engine as possible and send it to the environment. So, if the radiator clogs due to deposits or due to corrosion, it will certainly lead to the inefficient work of the entire cooling system and, respectively, which will be associated with the overheating of the engine.

Remember that scale in the cooling system will only increase and as a result, the cooling fluid may have obstacles to unhindered circulation in the system. This means that there will be a failure of a normal heat exchange, which will lead to the inevitable engine overheating. Of course, in this case it will be perfect if the driver notices the problem with overheating and turns off it, that is, immediately, as soon as the engine temperature is on dashboard Start rise.

Unfortunately, many drivers notice it too late. As a result, this leads to serious consequences and problems that with the cooling system itself and with the same engine.

Remember, even a short slightly overheating of the motor can lead to big problems. For example, damage to the same block head gasket.

Look carefully on deposits inside the car's radiator, the owner of which did not regularly change the antifreeze

To our happiness that you can purchase in an auto shop or hypermarket, which are able to increase the service life of the radiator and, accordingly, the service life of the engine. To do this, use the means to remove scale in the cooling system. This will help you significantly reduce the number of deposits in the radiator and in other components of the cooling system.

But you should still understand that the chemical processes that occur in the cooling system are so easy to stop, therefore, to keep the system in normal state, you must necessarily change the old antifreeze to the new antifreeze in this system (1 time in 2 years or 1 time in 3 years in the usual average annual car runs that do not exceed 40 thousand km during the operation of the car is not in a hot climate).

Here is what you have to do to independently change the antifreeze in the cooling system:

• - Wait until the engine cools after you drown out the car. Thus, you will make the antifreez replacement process safe, and all due to the fact that the cooling fluid cools.
• - Remove the radiator cover or the lid of the expansion tank to drop pressure in the cooling system.
• - Find in front of the car drain plug Coolant, putting a container for old antifreeze.
• - Unscrew the drain plug at the bottom of the radiator. As a result, the spent coolant will begin to drain.
• - After you have merged antifreeze, tighten the drain plug in place and fill the cooling system with distilled water.
• - Turn on the engine and the cooling system itself rings water through all its components. This not only woven inside the engine and the radiator, but may also help get rid of air bubbles that can be formed in the process of draining the old and bay of new antifreeze.

Also clogging by deposits in the cooling system can be observed in the radiator's inlet.

• - Add a flushing tool to the cooling system and let the engine on idlingTo rotate the washing fluid throughout the system.
• - Then, close the radiator lid or the cooling system expansion tank, pass a bit on the machine at high engine speeds to quickly bring the temperature of the power unit to operating temperature (Temperature between 90 and 110 degrees Celsius).
• - Mock the engine and wait until the engine cools down. Then, drain this mixture of water and flushing fluid by opening the drain plug of the cooling system again. As a result of such a washing, you get rid of most deposits in the cooling system.
• - Then, fill in the cooling system with the finished antifreeze (or a mixture of antifreeze and water concentrate in the ratio, depending on your area of \u200b\u200bresidence).
• - Start the engine by turning on the heating of the cabin to the maximum. This will allow you to get rid of the accumulated air in the system.

Pay attention that when the old antifreeze is drained, its color is likely brown or rusty. This is due to the internal corrosion inside the engine and the metal elements of the cooling system. But as soon as you promote the system with a special flushing agent, which will go through the entire cooling system several times, then the drainage fluid becomes more transparent, and maybe in it you will find white substances that were just the deposits in the radiator and in other channels of the cooling system. .

Also in auto shops for sale and various anti-corrosion products for the cooling system itself, which you can purchase and use together with flushing fluids. This will additionally increase the service life of the cooling radiator by car.

Despite the fact that the flushing of the cooling system may seem like a trivial procedure, in no case should be neglected by the owner of the car. Remember that the regular flushing of the cooling system and the frequent antifreeze replacement will actually increase the service life of the radiator and other components of the cooling system. So it is impossible to underestimate this procedure.
