Faulty radiator heater can becomequite 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 - the occupation is rather risky.
One of the frequent reasons why warm airor does not act 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 will 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.
Diagnose the obstruction of the heatersimple, 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 tapradiator, as it also often fails. But if the tap does not flow and it normally closes-opens, it is likely that it is sound, and the problem is in the heater.
When diagnosing a radiator obstructionthe stove is easiest to contact the service station, tell experts about the trouble, and they will eliminate everything themselves. This is much easier than cleaning the stove radiator yourself, but more expensive and longer. Is it worth it to waste money if you can solve such a 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.
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:
The cleaning process of the heater can be carried outtwo 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 the scale, 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 canto be carried out both with the help of special compounds for cleaning the cooling system, and with improvised means 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:
Choosing what to wash the radiator stove, without removingof course, it is better to give preference to professional means. But if they were not found, use household. But here you also need to consider some of the nuances.
In cars, radiators are used,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 flushing the stove on the car, it is necessary to find out what material it is made of.
Universal agents can be drinks like"Coca-Cola" and whey. The first acts more rigidly and is able to dissolve anything, but the second, on the contrary, has a soft effect on the metal, but its effectiveness does not decrease.
If you still decided 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 to begin with, 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, 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 beneficialin 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.
Now let's figure out how to clean the heater withoutdismantling. For this we need a Phillips screwdriver, a washing liquid, two hoses with a diameter suitable for the radiator pipes, a clean bucket and a watering can.
The cooling liquid can be drained from the system, andyou can and do not merge. 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 kink 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 connection we connect the hose with the watering canand begin to pour the active solution into the radiator. When the heater is full, let it sit for an hour or two. Next, drain 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 rinsing is complete, we spill everything with clean water.
To determine the patency of the heater, you can blow into the hose and, being guided by 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 fill the cooling liquid in the system to the required level.
