With the onset of cold weather, car ownersoften find that the heating system of their car salon is inefficient. It seems to be all right, but the air coming from the deflectors is not warm enough. Such a problem can be an indication that the radiator of the heater of the machine is clogged and can not pass through itself 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 to flush the radiator stove without removing it from the car. In addition, we will discuss what means are best for this procedure.
In modern cars use two typesradiator 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:
In addition, that warm air will cease to flow into the cabin in the right amount, a clogged radiator can cause:
The easiest way to get rid of thisThe problem is flushing the radiator stove. 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 whole 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.
Now we will understand what can be effectiveflush the radiator ducts. 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:
Self-cleaning the heater radiator withoutremoving it from the car or removing it - it is not important, should 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 washing liquidscooling system is an instruction for use, then with household powders, citric acid and soda should be extremely careful and know the proportions for the preparation of the solution.
Washing the radiator of the stove "Mole" providespreparation of liquid on its basis. This requires 10 liters of water and 100 g of the specified powder. Powder is covered in warm water, after which it is thoroughly mixed. After this, it is recommended to strain the received liquid (it is possible through an unnecessary female stocking). The same proportions are necessary for the soda solution.
To flush the stove heat sink with citric acidwas 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.
First, drain the coolant withsystem, preheating 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 join the previously prepared hoses, through which we will fill, and drain our cleaning solution.
Before washing the radiator of the stove, without removingit from the car, from it it is necessary to expel 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 radiator of the heater from scale.
In the first hose through the watering can begin to floodliquid. 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 heater radiator, attach to theit has communication hoses. Fill with coolant (better new) into the system. Start the engine and check the heater operation. If the situation has not improved, then it's time to replace the radiator.
