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 block. 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 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 liquid 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 The role of the purifier plays not water, 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.
How to clean the car's radiator outside and inside, knows not everyone, besides, many are not suspected at all that it needs to be done from time to time. Tell me, why hold such an event?
Cleaning the car radiator - is it necessary?
The car radiator is the necessary part of the cooling system, as it takes on a large flow of dirt. It occurs in liquid heat exchange with environmental. If the engine is overheat, which may occur due to the radiator fault, you will have to either change the motor or exercise it overhaul. Since first the liquid is heated, the electric fans will start working non-stop, will begin to increase the fuel consumption and, as a result, the engine communits.
The malfunction of this node of the machine occurs if it breaks garbage, insects, leaves, octoch, mud, rust. It is contaminated or not, it is possible to find out the antifreeze fusion. The presence of scale and rust in it suggests that it is necessary to immediately begin the flushing of the radiator. Therefore, in order to avoid unnecessary costs, it is necessary to wash and clean this unit in a timely manner both inside and outside. Let's try to figure out how to clean the radiator with outdoor And inside!
How to clean the car radiator outside and inside?
In the case of external cleaning, sometimes helps with compressed air. But it is recommended to wash with water under pressure. There is no time and the opportunity to remove this item, so you can clean without direct dismantling. The main thing is to be careful and not spoil honeycombs and tubes. Cleaning the car radiator occurs as follows: using soap water, remove the dirt from the grid towards its attachments, after that we rinse clean water. We do not advise to get involved in chemicals in order to avoid damage to the details of the cooling system.
Do not be lazy! After all, the flushing of the radiator extends its life and provides high-quality engine operation.
Now we'll figure it out how to clean the car radiator inside. This procedure can be performed at home. But if the outer cleaning does not require the removal of this item, then everything is more complicated here. You will need 5-7 liters of antifreeze, water or coolant, radiator washing, bucket, watering hose, keys, containers, gloves. First, give the engine to cool, otherwise there is a risk of burning, and the liquid can spoil hot parts.
Drain the cooler used. To do this, use the container so that the toxic fluid does not harm anyone. It must be installed directly below the valve. When you remove the radiator cover, pay attention to the springs. It requires replacement, if it is easy to compress or rusty. The same with hoses that remove hot liquid from the engine. Check if there is no crack or rust. Put gloves and drain the cooler. Now you can proceed to washing.
How to clean the car radiator inside - rinse competently
The ordinary garden hose fill with water radiator until it becomes transparent. If it is so polluted that they do not overcome water, then we use special tool To clean the car's radiator (for example, Anti-Nakipin)which fill and turn on the motor for 15 minutes for a better fluid distribution.
After the implementation of this operation, it is necessary to remove air from the system. To do this, with an open radiator again for 15 minutes, then turn on the heater for all power. The circulation of the cooler will push the air through the neck. Now fill the cooler to the required level, close and wipe all excess. So you now know how to make flushing. But if suddenly clean, as it should be, it requires replacement.
According to the regulations, the car washing the radiator should be carried out annually in the spring. However, depending on the number of heat exchangers used by the cooling liquids and operational features of the car, emergency cleaning of the heat exchanger is necessary. To do this, you should know signs of clogging, ways to clean and types of detergents suitable for this.
Construction of car radiators
The heat exchanger of the cooling system of the machine passes through itself antifreeze, with which the excess thermal energy is removed from the engine. The fluid should be cooled due to the high thermal conductivity of the radiator structural material (copper or aluminum alloy) and constant by blowing air, for which this node is made directly to the machine bumper.
On the other hand:
- all dust and dirt falling precisely on the heat exchanger grille, cleaning the radiator may be damaged by a mechanical random stone;
- when driving honeycombs, the thermal conductivity of the structural material falls;
- from the inside the tubes are clogged with scale and contained in antifreeze materials, it is necessary to clean the radiator with a special fluid.
IN modern cars In addition to the engine, cooling fluids are circulated in stove and air conditioning radiators. Therefore, for each of these nodes, washing the car's radiator with their own hands, and different ways. The easiest is the outer wash with a high pressure apparatus.
Signs of decline in heat exchanger efficiency
Since antifreeze reduces the temperature inside the heat exchanger exclusively due to air cooling, There is a dependence of the effectiveness of its work on the time of year, or rather the ambient temperature of the air.
Planned flushing of the engine cooling radiator is because it is carried out in the spring, which allows you to get rid of impurities inside the system before the hottest summer season, when heat loads reach their peak.
Symptoms of a decrease in the efficiency of the heat exchanger for the driver are:
- increased fan speed and its frequent switching on;
- problems with stove and climatic equipment;
- tableless antifreeze temperature sensor;
- inertness of the system on the signals of the row;
- interruptions in the work of the pump;
- uneven heat exchanger heating (hot upper nozzles, cold lower part).
In any of these cases will require washing automotive radiatorlike you a budget option troubleshooting. The outer sink of cells is vital in the presence of any number of dirt, dust, herbs that scored midges.
ATTENTION: Installation from the inside or outside the grid of the radiator of the protective mesh screen by 90% solves the last problem.
Popular Cleansing Tools
In specialized stores tool for high-quality washing The radiator is represented by a wide range. However, "Folk" methods and funds are often used to reduce repair budget. It should be remembered that not all of them are harmless to copper and aluminum, of which heat exchangers are made.
Folk
If budget cleaning is produced, the radiator is filled with folk remedies:
- three-axle carboxylic acid - flushing of the radiator from the inside with citric acid is effective for prophylaxis, but it is not possible to remove serious blockages, it is recommended to pour it for 3 days, then rinse the system with distilled water until it starts to merge clean fluid;
- Fed is the basis of the same citric acid, but in smaller quantity;
- serum - weakly concentrated lactic acid, poured only after filtering through the gauze, after 50 km of the run merges in the hot condition, washed boiled water or distillate;
- the caustic soda is caustic, only copper heat exchangers can be cleaned, pre-removed from the car, with disconnected pipes, is poured on ½ hours, washed with boiling water for 40 minutes, then frozen by air;
- tools for cleaning the sewage - Washing of a car with a radiator is allowed only for copper heat exchangers, aluminum is extended by sodium hydroxide after 15 minutes, the radiator will have to be changed entirely;
- saltic acid - a concentration of hydrochloric acid is allowed to 3% maximum and only for copper heat exchangers.
In principle, the car owner will help the table washing fluids For automobile units from different structural materials below:
ATTENTION: The appearance of a foam from the radiator indicates a caustic reaction with internal deposits, which is a normal effect for this cleaning method.
General principles when removing from narrow channels of third-party deposits are:
- when we rinse the system from dirt, you need to be prepared for the fact that these sediments could partially block small cracks, pores and holes, can "flush" pump and separate areas of the radiator;
- if the system, at least once, tap water was flooded, its acidity could be increased, which negatively affects the places of soldering by Tin, while even special additives in antifreeze are designed to protect tin.
Milk acid can not be compared in aggressiveness with caustic soda, however, this substance softens rust from the inside is better than all other products. The only problem is its absence on store shelves, because of what motorists have to make serum independently.
Special fluids
For external cleaning of the automotive radiator, special sprays in the canopy are considered the most effective. However, they are twice as expensive than similar products for the engine, and the composition is practically no different. Therefore, the engine is quite suitable for washing with a limited repair budget.
ATTENTION: Washing of a radiator car without removal by 30% is less effective in comparison with the cleaning of the heat exchanger, dismantled from the cooling system of the machine, and, among the same means.
- Kuhler-Reiniger - Manufacturer Liqui Moly., aggressive alkalis / acids does not contain, is considered a universal preparation for aluminum and copper heat exchangers;
- Hi Gear - divorced in water, poured for 7 minutes, only in the warm season;
- ABRO R Flush - is a corrosion inhibitor, poured for 10 minutes;
- Pingo - budget German;
- LAVR - in the composition there is a corrosion inhibitor.
Choosing a liquid for the internal cleaning of the heat exchanger, the factors should be taken into account:
- alkaline tools cope exclusively with the organic;
- acids dissolve inorganic products;
- neutral liquid is more suitable for prevention;
- two-component chemistry (acid + alkali) are outlined almost all compounds;
- however, two different means should not be used at the same time, if you are not a car chemical manufacturer.
For example, the domestic laurel, removing the problem of deposition of scale and deposit deposits, further improves antifreeze resource by 30%. And the American High Gier carefully refers to rubber parts of the system, which allows not to remove the heat exchanger during cleaning.
How can I wash?
There are a number of "folk" drugs, which, in principle, cope with the removal of deposits within the heat exchanger, can harm:
- when cleaning the Coca, the orthophosphoric acid contained in the drink will remove most chemical compounds, but carbon dioxide and dissolved sugar will result in problems;
- Fairy does not cope with engine oil from the outside, sharply increases labor costs when pouring inside the heat exchanger, since 10 - 20 buckets of water will be required to remove all the foam formed;
- White contains sodium hypochlorite, corrosive aluminum alloys, the corrosion rate increases with an increase in temperature;
- fluid Calgon and similar substances (for example, Tiret) are removed from the water supply line, but is almost useless for car cooling systems;
- blend of soda, citric acid and vinegar in proportion 2: 1: 1 is able to freeze rubber seals, therefore not recommended by experts.
In the extreme case, you can pour Coca-Cola for 10 minutes maximum, then rinse with plenty of water. White is contained in some cleaners (for example, in Mr.), so first it is necessary to study the composition of the tool that will be used.
Washing technology
The general principles of cleaning the heat exchanger machine for the user are:
- ideally, it is better to visit a hundred, having a special stand for washing radiators with adjustable temperature and head circulation treatment;
- the heat exchanger must be cleaned from the inside and outside, it is best to dismantle it before that;
- however, the old antifreeze will have to be replaced with a new coolant;
- therefore, the service will cost half the cost of a new radiator, if not more.
For example, spare parts for VAZ are quite cheap, it is easier to replace the heat exchanger entirely or make a flushing in the garage. To reduce repair time, it is better to serve all the radiators (DVS, air conditioning and heater).
From the inside
Cleaning the cooling system without dismantling the heat exchanger is made by technology:
- drain of antifreeze through the bottom stop;
- washing with boiled or distilled water;
- pouring detergent;
- washing with water;
- pour antifreeze and removal of air.
However, when using folk remedies, the liquid remains in the cooling system for several days. Only after that it merges for washing and filling the heat exchanger with antifreeze. When using some drugs, it is enough to start the engine for several minutes / hours.
It is much more efficient to clean the cooling system when the heat exchanger is removed. In this case, the radiator can be "shaken", tilt at different angles to merge from it, as much as possible sediment can be.
Outside
When processing the radiator, the other technology should be used:
- ensuring access - if the washing of the automotive radiator is made with their own hands at the place, without dismantling it, should partly disassemble the bumper, the grid or remove them entirely;
- foam application - spray spray from the heat exchanger on the manufacturer's instructions;
- flushing - foam is removed together with soluble mud with a ferry radiator, the nozzle must be adjusted to the slit jet.
ATTENTION: water under pressure can damage the cells of the heat exchanger, so the jet should be located at a right angle to the plane of the radiator, beat into the space between the plates parallel to them.
Radiator air conditioner
Since the air conditioner heat exchanger is built into the system radiator cooling in DVS Or is located next to him, there is no problems with cleaning the owner. The washing instruction is absolutely identical to the above technologies. Makes regular cleaning radiator more maintainable and increases its operational resource.
Radiator heater
In all heat exchangers, the car circulates the same liquid. Therefore, without removing the heat exchanger, its individual clearance is impossible physically:
- wash mixture poured into general System;
- rinsed it entirely;
- fill antiprooms completely.
To rinse the heat exchanger of the cooling system of the stove in place individually, it is disconnected from the pipes of the general system and collect in the scheme:
- both hoses from the heater radiator are stacked in a bucket;
- capacity is filled with detergent;
- the incision of one hose turns on the pump with power from the battery.
After that, the cleaner circulates in a small circle of heat exchanger - a bucket, like on the bottom photo.
After washing with distillate or boiled water, the heat exchanger is turned on into the general system, which is filled with the coolant for further operation.
Due to the small sizes of this node after removal, it can be washed in the bathroom, adjusting the temperature and water pressure, and, in both directions.
Thus, even without a special stand, the radiators of the air conditioner, the engine and heater can be washed with folk remedies or special cleaners own forces. It is enough to know which compounds in the detergent should not be, technology without removal and after dismantling the heat exchanger in all the details given in this manual.

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.
- Fly down the upper layer of pollution, flushing the cells with pure water pressure from the outer and inner side. 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. The chemistry is suitable as a special cleaner for washing the outer part of the radiator from Liqui Moly, and the usual engine cleaner or means for removing insects.
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.
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 work. 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 a 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 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.
The first is the people's way to clean 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, then choose the most effective toolwhich 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 starting work cooling system aerial traffic jams You will come out, it will only be to add antifreeze and close the lid.
