What to rinse aluminum car stove radiator and not harm him?

If in a few years of operation, the heater of your car began to warmly worse, the case is most likely to reduce the bandwidth of the stove radiator. In this case, it needs to washed. However, when performing this operation on an aluminum heat exchanger should be careful because not all means are equally safe for aluminum.

Is I guilty?

The fact that the stove warms no longer so effectively, there may be other reasons other than the above. Over time, the cells of the heat exchanger are clogged, salon filter. If the latter is still available for service, then clean the outer surface of the radiator is a whole epic, since it is necessary to disassemble almost the entire front panel.

Therefore, you should make sure that the reason is precisely in sediments inside the stove radiator. The simplest test method is based on the following. The new apparatus the whole surface warms with the same intensity. When the tubes begin to overcome mud and sludge, the temperature along the movement of the coolant decreases, just as a person with a brooded cholesterol with blood vessels flashes legs.

To check the engine and let him warm up to operating temperature. Then open all four diffusers on the front surface of the torpedo and turn on the maximum of the stove. Palms comparable air temperature coming out of different heater channels. Not bad to use the temperature measurement instrument - pyrometer. If the air is noticeably warmer from the supply tank, our suspicions are confirmed, and the radiator is subject to flushing.

A bit of theory

The process of washing products from aluminum and its alloys is not so simple. Tools commonly used for washing copper radiators are dangerous for aluminum. This is what the savings of automakers are turned around, the aluminum is widely replaced by copper. Therefore, it should be competently approaching the choice of washing products and liquids.

The fact is that aluminum, as an active metal, reacts not only with all alkalis, many acids, but even with water. Due to the oxide film on the metal surface, it exhibits corrosion resistance in the neutral medium (pH \u003d 7). Detergents with the acidic nature of exposure (pH<4,8) при определенной концентрации могут разрушать поверхность алюминия. Моющие растворы, обладающие щелочной реакцией (pH>9.5), for example - Potash, soda, caustic soda, aggressive in relation to aluminum.

It is sometimes argued that copper radiators should be washed with alkaline solutions, but aluminum - acid, since aluminum, they say, the acids are not afraid. In confirmation, the fact that nitric and sulfuric acids are transported in aluminum tanks are caused. And indeed it is. But the fact is that the activity of acids in relation to aluminum depends on their concentration. So, 98% sulfuric acid is little active to this material, as well as nitric. Moreover, they even contribute to the formation of a protective oxide film on its surface. But in dilute solutions of acids, silver metal corrosion fruit.

The main difficulty of selection of washing

When operating the engine in the cooling system (CO) of the engine internal combustion (DVS) various physical processes occur. The coolant (coolant) precipitate falls out of salts, products corrosion products, antifreeze oxidation, as well as fat and dirt. These components are dissolved with acids or alkalis:

a) corrosion products and scale. Most effectively dissolved with acids.

b) fat formations, spree products of antifreeze additives, oil. Neutralized by alkalis.

Since the interaction of acid with alkali, the neutralization reaction occurs, to combine in one tool, these components are impossible. That is, one deposits are removed only with acid, and others by alkali. Hence the output: or delete only those contaminants that prevail in a particular case, or use alternately both means. It is possible to determine the nature of contaminants only when plums from the system of old coolant. For example, what is more characteristic of testing: a fatty oil substance or scale of scale and rust. Today, all known means can only delete one type of pollution. In addition, acid flushing used in disruption of concentration and process technology can have a negative impact on components of CO.

If you score in the internet search engine - "than rinse the aluminum car stove radiator," the shaft of optimistic tips will be collapsed. At the same time, along with really adequate proposals, a lot of provocative recommendations on the topic - how faster "Upload" this node.

At the same time, some recommended means (citric acid, food vinegar) can still be used in the extreme case by observing a reasonable proportion. So, mortar citric acid Make a 200 - 250 g of powder for 10 liters, the table vinegar is bred in an amount of 500 ml per bucket of water.

We remind you: the concentration of acetic acid is 70%, which must be taken into account when calculating the proportion.

Fans of refreshing beverages of Coca-Cola, Fed and others like them forget that these liquids have a sharply pronounced acid reaction, it also contains sugar, which can be delayed in the system. Does it make sense to be used to wash the radiator household cleaners such as Domasestos, Comet, Mole, when produced washing fluidsdesigned specifically for systems cooling in DVS? Saving B. this case Does not justify possible harm.

Attention: most alkalis (food soda, potash, caustic soda) for aluminum radiators are contraindicated.

And what to choose?

Domestic and foreign manufacturers offer various products designed to flush the cooling systems of the FRO. As an example, consider flushing funds from the company Lavr (Russia):

• LAVR RADIATOR FLUSH PLUS - with strong surface clogging. The volume of the solution is 9 - 11 liters.
• Radiator Flush 2 × 1 (LN1106) - for extremely contaminated CO: Solvent of scale + converter-rinser.
• Radiator Flush Complete is a comprehensive cleaner. Safe for radiators and stoves with small cross-section tubes. By 9 - 11 liters of volume.

Foreign analogues: Liqui Moly, Hi-Gear, Felix and others.

Any car enthusiast that operates one car for 3-5 years, probably noticed the deterioration of the salon heater. Traditional repair method - dismantling internal heat exchanger with subsequent cleaning channels. There is a common problem: it is not easy to remove the element, some cars have to disassemble half the front panel. Therefore, many drivers practice an alternative - liquid flushing of the stove radiator without removing from the car.

The frequency of the heater service

Most of the antifreeze time in the cooling system operates at a temperature of 80-95 degrees. On the inner surfaces of metal tubes in contact with the outer air, deposits are gradually growing. The cross-section of the coolant duct nozzles is reduced, the heat exchange intensity is reduced.

The reasons for the formation of a precipitate that impedes the normal heat transfer of radiators:

• the late replacement of old Tosol, whose additives have lost job properties and began to fall out with a precipitate;
• the use of tap and distilled water instead of antifreeze leads to elevated salt deposits (scale);
• fill fake coolant;
• the system travels small particles, clogging tubes stove, - metal chips, rust, sealant and rubber pieces.

The optimal interval for washing the stove radiator is 1 time in 2-3 years. The operation is performed simultaneously with the replacement of antifreeze - the system is emptied, filled with distilled water with a special cleaning agent and warms together with the engine to operating temperature. The solution is then removed and poured through expansion tank New Tosol.

If the above-described prophylactic flushing was made for many years, to restore the normal heat exchange, the heater radiator will have to be cleaned of scale and garbage. In order not to bind to the disassembly of the cabin, rinse the stove without removing from the car one of the two methods described below.

How to wash the cells of the heat exchanger?

To remove sediments and dirt from the cabin heater radiator, the following chemical compositions are allowed:

• detergent for cars sold in specialized stores (for example, from the Mannol brand);
• food citric acid;
• household reagents designed to clean sewer pipes;
• soda caustic solution.

Council. Before buying a washing makeup, check out what material is the stove of your car - aluminum or copper. Relants, well cleansing copper tubesmay cause harm to aluminum soot of heat exchanger.

The radiator made of copper is allowed to rinse with all the means listed. Single caution: carefully examine the instruction of the household reagent and make sure that the liquid does not damn the rubber hoses and plastic details. With severe clogging, it is better to purchase two chemicals on an acidic and alkaline-based basis.

Since the aluminum stove radiator does not tolerate contact with the alkali, it is necessary to purchase citric acid or factory automotiveintended for similar heat exchangers. In extreme cases, weakly use weak alkaline solutions with a subsequent washing distillate.

Preventive cleaning "On the go"

This method is recommended to be implemented in the absence of frosts - in the summer, early spring or late autumn. Cause - Filling the cooling system power aggregate distilled water for several days. Due to night frosts, heat exchangers tube can crack from the expansion of ice. Permissible to perform flushing measures in winter if vehicle Stored in the warm garage and does not stay for a long time.

How this cleaning is done:

1. Fully empty the engine cooling system.
2. Take the right amount of distillate corresponding to the system volume. Heat water and dissolve 100-150 grams of citric acid in it.
3. Fill the remedy for antifreeze place, make sure there are no air traffic jams.
4. Ride on water with citric acid 4-5 days, then drain the solution. Fill the cooling shirt of the motor and the network of pipelines to new Tosol a suitable brand.

Note. The concentration of the food acid is 100 grams per 10 liters of water is considered rather weak - the solution is unable to damage any parts and cells of radiators.

Flushing "On the go" - the event is prophylactic. The heat exchanger is strongly crashed in this way, it will not be possible to clear it, you need a higher concentration of acid and reverse flushing.

Preparation for overhaul

To clean the radiator of the salon heater right on the car you will need:

• the detergent of two types is alkaline and acidic;
• standard set of keys, screwdrivers and passage, funnel;
• water pump low power (a household circulation unit is suitable for heating and an electric pump from the Gazelle truck);
• two 2 meters long hose with protracted clamps;
• water distilled in the amount of 3 volume of the cooling system of your car;
• boiler and bucket;
• old categorous tights or threefolded march.

Also prepare the container for the drain of old antifreeze and the required volume of fresh coolant. Often car enthusiasts are washed with a stove heat exchanger without complete emptying of pipelines and engine shirts, but then the whole garbage contained in the old antifreeze is riveted again into a clean radiator.

Work is more handy in the garage equipped with a viewing channel. To remove deposits without removing the stoves from the car, completely drain Tosol from the motor in the following order:

1. Give the engine to cool to room temperature and substitute the tank below the antifreeze.
2. Unscrew the plug on the cylinder block, then open the lid of the expansion tank.
3. When the whole toosol is found, wrap the plug in place. If a second drain neck is provided in the main radiator, repeat the operation.
4. Disconnect the pipe at the highest point of the system - on the heating unit throttle valve either carburetor.

On some cars, emptying hinders hinders that protect the inconsistent space from the dust from the bottom. There are 2 options for solving the problem: to remove the protection or use the long hose attached to the neck after the cork is unscrewed.

Procedure for conducting work

To clean the stove with your own hands, you need to find and disconnect 2 nozzles from open space inside the cabin. The moment is second: Make sure the heater crane located inside the cabin is open. Next, assemble washing unitincluding such elements:

• 2 hose;
• water pump;
• filter from tights.

The task of the filter is to not allow dirt and scale particles inside the pump unit, so it must be installed at the end of the hose coming from the heat exchanger. Connect another pipe to the pump immersed in a bucket with washing solution. If you use the pump from Gazelle or the circulation pump, you will have to put a short hose for water supply from the bucket.

Before washing the car stove radiator, connect the hoses of the homemade installation to the heat exchanger pipes. Further act according to the instructions:

1. With a boiler, heat the water in the bucket to a temperature of 70-85 ° C.
2. Turn on the pump by lowering the reverse hose in the bucket. When a steady stream go out of it, add to hot water Cleaning means for the sewage type "Mole" or similar (number - at least 1 liter).
3. Rinse the stove for 30 minutes, periodically including boiler. Do not allow the solution to cool or boil.
4. After half an hour, stop the pumping and remove the dirt from the filter. Then swap suction and return hose any in a convenient way - Switch the nozzles by the machine or the pump unit.
5. Run the pumping again. The inverse cleaning of the stove radiator is performed at mandatory and lasts 30 minutes.

Important moment! If the heat exchanger is made of aluminum alloy, the processing time by the sewer reagent must be reduced to 10-15 minutes. As a rule, such chemicals are made on the basis of alkali and are able to freeze the cells of the radiator.

The second stage is washing the stove with clean water - produced in a similar way. First, the water is served in one direction, then to another, the time of pumping is 15 minutes. Then replace the filter and proceed to the third stage - acid processing.

To clean the radiator with a solution of citric acid, pour into hot water 100-150 grams of the reagent and mix thoroughly. Connect all hoses and start the pump unit again. The removal of scale acid lasts from 30 to 60 minutes, depending on the degree of contamination of the internal surfaces of the heat exchanger. Do not forget to maintain the temperature of the solution and make the reverse flushing (also 30-60 min).

The last stage is the final flushing of the stove from scale and acid distilled water. Drink it in both directions for 15 minutes, after which stop the pump and blow the remnants of water from the heat exchanger. The assembly and filling system is made in the following order:

1. Connect the full-time connections of the salon heater.
2. Close everything drain holes And slowly pour antifreeze through the throat of the expansion tank.
3. When from the nozzle taken from the throttle block, Tosol flows, put it onto the fitting and secure the clamp.
4. Follow the coolant to the norm.

At the end of the assembly, get the engine and warm up to the operating temperature of 90-95 ° C. Check the performance of the heater, turning on the heating and the fan on full power. In case of successful flushing, you will feel the result without measurement by the thermometer.

The radiator fault of the heater can be a sufficiently unpleasant surprise for the car driver, especially in winter time. And the point here is not so much in comfort as safe. The frozen glasses can be cleaned outside, but get rid of fogging and frosting on their inner surface without warm air it is unlikely to succeed. And a limited review - a rather risky occupation.

One of frequent reasonsfor which warm air Or does not come at all, or it goes into the salon, is clogging the heater radiator. This phenomenon is familiar to the majority of our motorists, so they learned to fight him.

In this article we will talk about how and than rinse the stove radiator without removing it from the car, and with dismantling, as well as consider what means can be used for this.

How to understand what cause is in the radiator

Diagnose the impassability of the heater is easy, especially if you are sure that the water pump (pump) works properly, and the coolant (coolant) circulates in the system in normal mode. War down car engine to operating temperature, open the stove crane and take it with hand input and outlet nozzle radiator. If the difference in their temperature is tangible, it means that the coolant does not enter the heater or not in full.

Next, you need to make sure that the problem is not in the tap of the radiator, as it also often fails. But if the crane does not flow and normally closes, opens, most likely, it is working, and the problem is in the heater.

When diagnosing the obstruction of the stove radiator, the easiest way to contact the station maintenance, Tell specialists about trouble, and they themselves will eliminate everything. It is much easier than rinse the stove radiator itself, but more expensive and longer. Is it worth spending if similar problem Can I solve yourself by spending thirty minutes and several tens of rubles? For this, of course, you need to know how the cleaning and flushing of the car stove is done at home. But first will understand the causes of malfunction.

Why the radiator is clogged

The impassability of the heater radiator is due to the layering on the inner surface of its skipping tubes and dirt. The reason for this may be:

• long-term operation without prevention;
• the use of low-quality cooling fluids;
• late replacement of coolant;
• use as water treatment, especially with a large salt content;
• getting into the oil, fuel, dirt.

What is the essence of the cleaning of the stove radiator

The process of cleaning the heater can be carried out by two methods: stoves with removal and removing it from the car. In both cases, the procedure is to pour into it a chemically active substance capable of dissolving scale, and then, preferably under pressure, rinse it, extinguished, thus all the solubular dirt. Consider both options.

Than rinse the stove radiator without removing it

Cleaning the heater without its dismantling can be performed as with special compositions To clean the cooling system, so and underwater means that can be found in the kitchen. Moreover, the latter in some cases act more efficiently compared to professional fluids.

What to rinse the stove radiator without removing it from the car? Practice shows that from the primary means it is best to cope with this task as follows:

• hot citric acid solution;
• solution;
• various powders and liquids for the type "comet", "Tyr", "Mole", etc.;
• milk serum;
• drinks "Coca-Cola", "Fanta", "Sprite".

Choosing than washing the stove radiator without removing it, preference, of course, is better to give professional means. But if such were not found, use household. But here you also need to take into account some nuances.

What heater than rinse

In cars used radiators made of copper-brass alloy, and aluminum. These metals react differently to acid and alkali. Remember: It is impossible to wash with alkaline solutions, and copper - acidic. If you make a mistake, you can significantly aggravate the situation. Therefore, before rinse the stove on the car, you need to know from which material it is made.

Universal means there may be drinks like "Coca-Cola" and the first acts more rigidly and can dissolve anything, and the second, on the contrary, has a soft effect on the metal, but its effectiveness is not reduced.

Shot from the car

If you still decided to remove the heater for cleaning, then best way Its restoration will be washing under the jet of water, for example, in the bathroom. But to begin with, it is desirable at least for an hour to pour into it any active liquid corresponding to its material. To do this, one of the nozzles should be shuffled with something, and in the second pour the solution until the radiator is filled. After an hour-two liquid we drain, and we rinse thoroughly, sending the water into one of its connections. When from another nozzle will begin to flow pure waterThe procedure can be completed.

The method of cleaning the heater with his dismantling is beneficial to the fact that it makes it possible to clean it also outside, while rinse the stove radiator without removing it, you can only from the inside. Very often, its lamellas are so contaminated that the free circulation of air between them deteriorates significantly. This can lead to a violation of heat exchange and overheating of the system.

How to rinse the stove without removing the radiator

Now we'll figure it out how to clean the heater without dismantling. To do this, we need a cross screwdriver, a washing liquid, two hoses with a diameter suitable under the radiator nozzles, a clean bucket and a watering can.

Cooling fluid can be drained from the system, and you can not merge. In the second case, it will also be necessary for the top for the topping, because during the process, in any case, without loss can not do. Consider the option without draining the coolant.

To begin with overlapping the heater crane. IN motor compartment Car we find the input and outlet nozzles of the radiator. Screw the screw on the clamp, pressing the hose to the inlet nozzle. We disconnect the hose and immediately plug it or bend. The same is done with the second nozzle, only on it immediately put on another hose prepared in advance. We take it under the bottom of the car and omit into clean capacity. Opening the heater's crane, merge the coolant. When she escapes, run the output hose.

Connect the hose with watering and we begin to fill an active solution into the radiator. When the heater is filled, give him an hour or two. Next, we drain the solution, and in the watering can pour cleaning fluid in such a way as to wash the radiator. This may require 5-10 liters of solution. After the flushing is complete, shed all clean water.

To determine the patency, the heater can be poured into the hose and, focusing on the resistance to the airflow, determine its condition. If necessary, the washing procedure can be repeated.

At the end of cleaning, we make installation of hoses to the radiator. Take the cooling fluid to the system to the required level.

Several tips to help maintain the heater radiator clean

1. Do not pour cheap coolant or water into the cooling system. For establishing suitable engine Your liquid car use the user manual and the tips of the manufacturer.
2. In no case do not mix antifreeze with Tosol, and vice versa. These two liquids take into a reaction to the reaction, forming a precipitate.
3. In time, make a replacement of Co. in accordance with the recommendations of the manufacturer.
4. Pay attention to the condition of the heater radiator hoses, as well as check the performance of its crane.
5. Do not allow oil cooling, fuel, other liquids into the cooling system.

The cleaning of the radiator is needed when it comes from the air duct in the cabin instead of warm air. But first of all, other breakdown options exclude. It is necessary to check the help of pump, thermostat, fan, cooling systems, antifreeze levels, air ducts. If everything is in order, then the cause of the fault is precisely in pollution in the stove radiator. Dirt clogs cells, giving malfunctions. The air temperature, heating car from the inside, decreases. The tips below will help the driver to correct the unpleasant situation.

How to rinse the radiator of the stove of automotive chemistry

For example, the MANNOL fluid is taken, it is perfectly coping with the washing of the cooling system. When working with chemistry, we use rubber gloves and a mask protecting against poisonous evaporations. Before starting to prepare a compressor, clamps, clean bucket, fump (carving seal). We need 2 hoses with adapters, one part of which will be on the radiator hoses.

Start with the attachment of the main hoses with additional. This is done by clamps and winding fumlents. The compressor blows the heat exchanger. MANNOL poured, actions of 30 minutes. With very complex cases, it is increased to 2 hours. Next, the liquid is drained, the stove is washed to purity by water under pressure, using the pump. Purplized by a compressor, antifreeze with inspection of air stoppers is poured, if necessary, fills.

How without removing rinse radiator lemon acylock

Composition of a homemade cleaner: citric acid 100 g per 5 liters of distilled water. Old cooling fluid varies with places with citric acid solution. The car should pass on a solution of 5 days. At the end of the term will make a scale and dirt. The radiator is cleaned with water under pressure, dried with a compressor and filled with new antifreeze.

How without removing rinse the radiator stove with vinegar

It will take 3 bottles of 70% of the table vinegar, the capacity of 1 bottle of 180. Antifreeze on a plot - 1 l, or a replacement of 5 liters. In the case of antifreeze mixed with a sealant, it is completely changed. The cleaning process begins with the empty of the cooling system. The cooler merges into the pure plastic bucket, 2 nozzles are removed. With the help of the compressor residues blow out. The heater is washed with water and frozen air. In order to avoid burns on the body of vinegar, rubber gloves and a protective mask are put on. All vinegar is poured for 4 hours. The car is set at an angle so that the vinegar filled all the "honeycombs". Raise the auto lift or driving onto the hill, the overpass. Conduct the car to 5000 revolutions for 5 minutes. So kicked out air traffic. The system is washed under pressure. The results are visible at the bottom of the bucket. After washing, the compressor should be purged, the nozzles removed, poured new antifreeze In the expansion tank or fills to the old. Engine starts, the cooler level is controlled.

How to wash the radiator of the stove "Mole"

Many ways are used for flushing. But with some variations you need to be very careful, there are more harm from them than good. It will be about mole-type fluids. The concentrate is not applicable to aluminum radiators, there are aluminum, caustic soda, which corrosive aluminum. If such a combination is used - to be trouble. You can safely buy a new device. It is better to dissolve the "mole", and strictly control the time of work.

Granulated "mole" solution: a proportion of 15 g by 0.5 liters of water, leave for 40 minutes. Copper only, temperature 90 ° C. In order to avoid chemical burns of the skin and mucous membranes, be sure to work in rubberized gloves and mask! Capacity for measuring the volume is a larger glass bank than the amount of fluid itself. Pour until the temperature fell. White foam should be isolated, rinse for a long time with flowing water under pressure and compressed air.

Cleaning makes other ways. For example, soda or even a popular Coca-Cola drink. It is important to pay attention to the integrity of the hoses, perhaps there are small holes, also check the clamps. If the cleaner did not help, it is recommended to turn to the professionals of your business, that is, in the car repair shop, they will help to understand the problem.

Many car sellers are delivered from their "product" in the summer. The fact is that in the warm season you can hide such a serious car malfunction as a breakdown of the stove. With the onset of cold weather, drivers, turn on air blowing, and from the flap begins blowing cold air. All this indicates that the stove has been hammered and needed to rinse. However, disassemble the panel and remove the stove in the cold is quite problematic. Therefore, today you will learn how to wash the stove radiator without removing that you need it for this, but at first we will try to figure out why the radiator is clogged.

Why is the stove radiator clog?

It is clear that the scored radiator is not a normal phenomenon for the car and this phenomenon has a completely explaining reason. The thing is that in the input process in the summer, the inner walls of the radiator tubes are subjected to increased oxidation, since the circulation of fluid in the stove is missing. The oxidation product settles on the walls and covers all their area, while having the smallest thermal transmission coefficient. As a result, copper or aluminum tubes of the radiator are not heated and the heater blows with cold air.

Another reason for clogging of the radiator is the use of antifreeze is not the best quality. Here you need to please highlight on the price of coolant. As a rule, antifreeze of poor quality, in most cases, does not contribute to the proper operation of the cooling system.

All these problems can be eliminated by three in different ways:

• . Elementary way to get rid of many problems at once, but not the most economical, so the price of a new radiator is quite large.
• After removing it from the car. This method is not related to the cost of new spare parts and allows you to achieve maximum effect. However, it has one essential drawback - high laboriousness. Remove the stove radiator from the car panel is quite difficult.
• Wash radiator without removal. The most economical and fast option. Allows you to return the stove radiator into a working position without removing it. This method we will consider below.

What do you need for washing?

First of all, you need to visit the chemistry store. You will need special pipe-based purifiers based on alkalis, acid for dissolving them, as well as special substances that allow you to get rid of scale. Many car enthusiasts are used for these purposes. acetic acidwhich also copes well with the task. However, it is not necessary to confuse it with a table vinegar.

• It will take anyone capacity capacity of at least 30 liters. Next you will learn what. And in advance, in two hoses of sufficient length.
• New antifreeze. It's not necessary to change it at all, but why not take advantage of the case and not change it in advance? After all, it will relieve you from the opportunity to climb a car with a basin in the future. In addition, prepare enough water. Using it, you will dissolve the prepared mixtures, and after - flush from residues.
• Pumpwhich has the principle of the "River". Its main feature is that it pumped water with a certain vibration, which will be very useful when washing such thin radiator tubes. The second plus can be called that it has such an opportunity as the lower fence of water, which will be very relevant.

How to clean the radiator without removing?

Connect the stove radiator again to the engine cooling system, and. Check the stove. If warm air go out of the flap, then you did everything right. But it is possible that the malfunction can be covered not only in a scored radiator, you can search for the problem and elsewhere, for example, in improper setting of dampers, or a closed stove crane, which for some reason does not open.

Rinse the stove radiator can any car enthusiast and for this you do not need to have any special knowledge in chemistry.
