Flushing the radiator of the stove without removing it. How to rinse the radiator of the stove without removing it?

With the onset of cold weather, car owners often find out that the car's heating system works ineffectively. It seems to be all right, only the air coming from the deflectors is not warm enough. Such a problem may be an indication that the radiator of the car heater is clogged and can not pass through it the prescribed amount of heated coolant.

How to be in a similar situation: replace the heater or try to repair it? Do not rush to resort to radical measures. If the heat exchanger does not flow, it can be restored.

In this article, we'll talk about how the radiator is flushed without removing it from the car. In addition, we will discuss what means are best for this procedure.

Why is the radiator clogged?

In modern cars use two types of radiator heaters: copper-brass and aluminum. Each of them has advantages and disadvantages, but all of them are subject to oxidation and corrosion. Over time, the channels of any radiator lose their throughput due to deposits on the inner walls. To speed up this process can also:

• Poor-quality coolant;
• Use of various cooling fluids;
• Getting into the system of various debris or active substances, such as oil or gasoline.

Consequences of the heat sink obstruction

In addition, that warm air will cease to flow into the cabin in the right amount, a clogged radiator can cause:

• Engine overheating;
• Increasing the pressure in the cooling system;
• Depressurization of cooling system components;
• Failure of the safety valve of the expansion tank, etc.

How to deal with this

The easiest way to get rid of this problem is to flush the stove radiator. Its essence is to drive through it a special remedy capable of dissolving and washing all the scum and dirt. There are two ways of cleaning: washing the radiator of the stove without removing it from the car and removing it. The first method does not involve the dismantling of the heater. It simply disconnects it from the cooling system. In the second case, the heat exchanger is dismantled, and the entire procedure can be successfully carried out even in the bathroom. We will dwell on the first option, since flushing the heat sink without removing it is much easier. And given that in some cars to get to the heater is not so simple, even faster.

Effective means for washing the stove

Now we will understand what can effectively clean the radiator channels. Simple water for this, you see, is unlikely to fit. Flushing the radiator of the stove provides for the pouring into it of means that are capable of destroying the scaling formed and deposited on the walls. These means can be:

• Special fluids for flushing the cooling system (factory-made);
• Household tools for cleaning sewage pipes and removing scale (Mole, Comet, Tiret, Calgon, etc.);
• Acid solutions (citric acid, acetic acid);
• Alkaline solutions (caustic or calcined soda) ;
• Beverages of the "Fantasy" or "Coca Cola" type;
• milk serum.

Do no harm

Self-cleaning the radiator of the stove without removing it from the car or removing it is not important, it must take into account the properties of the material from which the element is made. In no event should alkaline solutions be used to clean aluminum heaters. The metal will instantly become oxidized, and the situation will only get worse. The same will happen if you add acid to the copper radiator. Therefore for aluminum - acidic means, for copper - alkaline.

Universal means can be considered heated to boiling "Coca-Cola" or "Phantom", as well as milk whey, which has a "mild" destructive effect on the scum.

If special fluids for washing the cooling system have instructions for use, then with household powders, citric acid and soda, you must be extremely careful and know the proportions for the preparation of the solution.

How to prepare a solution

Washing the radiator of the stove "Mole" involves the preparation of liquid on its basis. This requires 10 liters of water and 100 g of the specified powder. The powder is poured into warmed water, after which it is thoroughly mixed. After this, it is recommended to drain the received liquid (it is possible through an unnecessary female stocking). The same proportions are also necessary for soda solution.

To rinse the radiator of the stove with citric acid was the most effective, it will require at least 300 grams per 10 liters of water (30 packs of 10 grams). After dissolution, the resulting liquid must also be filtered.

How to rinse the radiator of the stove without removing it from the car: Instruction

First, drain the coolant from the system by preheating the engine. Then we find the inlet and outlet pipes of the radiator of the heater and, loosening the clamps, we disconnect the rubber hoses from them. In their place we add pre-cooked hoses, through which we will fill, and drain our cleaning solution.

Before you wash the radiator of the stove without removing it from the car, you need to get rid of all the dirt that has not yet settled on the walls. You can do this with ordinary tap water. For this, one of the hoses is filled with water (10-20 liters), allowing it to flow from the other end.

Only after this, it is possible to start cleaning the heater heat sink from the scale.

In the first hose through the watering can begin to fill the liquid. The end of the second hose is lifted slightly, and after the solution flows out of it, overlap it. When the stove is fully filled, we also cover the first hose. We leave the radiator for 2-3 hours, so that the scum has time to otkisnut. After this, it must be rinsed again with water. If necessary, the procedure can be repeated.

After cleaning the radiator of the stove, attach the communication hoses to it. Fill the coolant (better new) in the system. Start the engine and check the operation of the heater. If the situation has not improved, then it's time to replace the radiator.

Helpful Tips

1. Do not use water, especially unrefined, as a coolant. In the composition of ordinary tap water, too many different salts that will subsequently settle on the walls of the radiator.
2. Do not buy cheap coolants of doubtful origin. It is not known what substances are included in their composition and how they will "get along" with the metal from which the radiator of the stove is made.
3. In due time, replace the coolant in accordance with the recommendations of the manufacturer.
