Than to wash out a radiator of an oven, without removing. Than to wash out a radiator of an oven?

Malfunction of the heater radiator can become quite an unpleasant surprise for the driver of the car, especially in the winter. And it's not so much about comfort, it's about safety. Frozen glass from the outside can be cleaned, but get rid of fogging and frost on their internal surface without warm air is unlikely to work. A ride with a limited view - a rather risky occupation.

One of the frequent reasons for which warm air or does not flow at all, or weakly enters the interior, is the clogging of the radiator of the heater. This phenomenon is familiar to most of our motorists, so they learned to fight it.

In this article, we'll talk about how and what to clean the stove radiator without removing it from the car, and with dismantling, and also consider what means can be used for this.

How to understand that the reason is in the radiator

It is not difficult to diagnose the obstruction of a heater, especially if you are sure that the water pump (pump) is working properly, and the coolant (coolant) circulates in the system in normal mode. Warm up the car engine to operating temperature, open the stove cock and touch the radiator inlet and outlet connections with the hand. If the difference in their temperature is noticeable, then the coolant does not enter the heater or does not come in full.

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

When diagnosing the obstruction of the radiator of the stove, it is easiest to contact the service station, tell the experts about the trouble, and they will eliminate everything themselves. This is much easier than washing the radiator of the stove yourself, but more expensive and longer. Is it worth it to waste money if you can solve this problem yourself, having spent thirty minutes and several tens of rubles on it? For this, of course, you need to know how to clean and flush the car heater at home. But first we will understand the reasons for the malfunction.

Why is the radiator clogged?

The obstruction of the radiator of the heater is due to the build-up of scale and dirt on the inner surface of its pipes. The reason for this may be:

• Long-term exploitation without prevention;
• Use of poor-quality cooling liquids;
• Untimely replacement of coolant;
• Use of water as coolant, especially with a high content of salts;
• Getting into the system of oil, fuel, dirt.

What is the essence of cleaning the heater radiator

The cleaning process of the heater can be carried out by two methods: flushing the radiator of the stove with removal and without removing it from the car. In both cases, the procedure consists in pouring into it a chemically active substance capable of dissolving scum, and then, preferably under pressure, rinse it, thus driving out all the dissolved mud. Let's consider both variants.

Cleaning the heater without dismantling it can be done both with the help of special compounds for cleaning the cooling system, and with improvised tools that can be found in your kitchen. And the latter in some cases are more effective than professional fluids.

Than to wash out a radiator of an oven, not removing it from the car? Practice shows that the best tools for coping with this task are:

• A hot solution of citric acid;
• Caustic soda solution;
• Various powders and liquids for cleaning sewage pipes of the type "Comet", "Tiret", "Mole", etc .;
• milk serum;
• Drinks "Coca-Cola", "Fanta", "Sprite".

Choosing what to clean the radiator of the stove without removing it, the preference, of course, is better given to professional means. But if they were not found, use household. But here you also need to consider some of the nuances.

Which heater than to wash

The cars use radiators made of copper-brass alloy, and aluminum. These metals react differently to acid and alkali. Remember: the aluminum radiator can not be washed with alkaline solutions, and copper - acid. If you make a mistake, you can significantly exacerbate the situation. Therefore, before cleaning the stove on the car, it is necessary to find out what material it is made of.

Universal means can be drinks like Coca Cola and whey. The former acts more rigidly and is capable of dissolving anything, but the other, on the contrary, has a soft effect on the metal, but its effectiveness does not decrease.

Than to wash out the radiator of the stove, taken from the car

If you still decide to remove the heater for cleaning, then the best way to restore it will be rinsing under a stream of water, for example, in the bathroom. But first, it is advisable to pour at least an hour into it some active liquid corresponding to its material. To do this, one of the nozzles should be something to plug, and in the second fill the solution until the radiator is full. After an hour or two, the liquid is drained off, and the heater is thoroughly rinsed, sending a stream of water to one of its nozzles. When clean water starts to flow from the other branch pipe, the procedure can be completed.

The method of cleaning the heater with its dismantling is advantageous in that it makes it possible to clean it from the outside as well, while it is possible to rinse the radiator of the stove without removing it, only from the inside. Very often its lamellas are so polluted that the free circulation of air between them significantly deteriorates. This can lead to a violation of heat transfer and overheating of the system.

How can I flush the stove without removing the radiator

Now let's figure out how to clean the heater without dismantling. To do this we need a Phillips screwdriver, a washing liquid, two hoses with a diameter suitable for radiator connections, a clean bucket and a watering can.

The cooling liquid can be drained from the system, or it can also not be drained. In the second case, you will also need the coolant for topping, since during the process, in any case, you can not do without losses. Consider the option without draining the coolant.

To begin, we shut off the heater tap. In the engine compartment of the car we find the inlet and outlet nozzles of the radiator. Using a screwdriver, loosen the screw on the yoke, pressing the hose to the inlet pipe. Disconnect the hose and immediately plug it or bend it. The same is done with the second branch pipe, only on it we immediately put on another hose, prepared in advance. We deduce it under the bottom of the car and lower it into a clean container. After opening the heater tap, drain off the coolant. When she escapes, we bend the output hose.

To the inlet branch pipe we connect the hose with the watering can and begin to pour the active solution into the radiator. When the heater is full, let it settle for an hour or two. Next, merge the solution, and pour the cleaning liquid into the watering can so that the radiator is rinsed. This may require 5-10 liters of solution. After the rinse is complete, spill all with clean water.

To determine the patency of the heater you can blow into the hose and, focusing on the resistance to the air flow, determine its state. If necessary, the washing procedure can be repeated.

At the end of cleaning, we mount the hoses to the radiator. We add the cooling liquid to the system to the required level.

A few tips to help keep the heat sink clean

1. Do not fill in cooling system cheap coolant or water. To determine the proper fluid for your vehicle, refer to the owner's manual and manufacturer's advice.
2. Do not mix antifreeze with antifreeze, and vice versa. These two liquids react with each other to form a precipitate.
3. In time, replace the coolant according to the recommendations of the manufacturer.
4. Pay attention to the condition of the heater radiator hoses, and also check the operation of its crane.
5. Do not allow oil, fuel, or other liquids to enter the cooling system.
