How to change the radiator of the stove to VAZ 2109. Available ways to replace the radiator stove VAZ 2109 own

From the article you will learn how to change the radiator of the stove to VAZ 2109. This procedure is not very difficult, but it will require patience and some knowledge from you. As you know, the interior heating is connected to the cooling system. Therefore, you will need to completely drain the liquid. This must be done first of all, so that the interior does not get antifreeze. Otherwise, it threatens that the humidity will be high, and an unpleasant smell will appear. Carpet begins to break down, he will be putrefied. The process can go to the body elements. And this is fraught with expensive repairs.

Electrical faults

To eliminate all the causes of the failure of the stove, you need to know its main device. Please note that the forced air flow is created by the electric motor, which is installed in the engine compartment. If it does not work at any speed, then it can be judged that the fuse through which the power of this device is being fired. By car VAZ 2109, the repair of the stove - sometimes hard and tedious, but you can do it. In the same case, if any one fan speed is working, and the rest is not, then most likely there is a resistance damage, which is installed near the driver's right foot. It is also possible that the wiring of the control circuit has been interrupted. Regardless of what happened, you need to check the entire electrical circuit completely. Very often, there are problems directly in the switch. It often burns contacts. In this case, only a complete replacement will help. Sometimes the motor itself rotates very slowly, despite the fact that the maximum speed is turned on. In this case, only the replacement of the electric motor of the VAZ 2109 will help . Repair of this device, as a rule, is impossible.

Symptoms of a radiator failure

The surest sign is the appearance of puddles of coolant on the rugs of the driver and passenger. True, sometimes there is such a leak that does not betray itself immediately. Because all the liquid accumulates under the mat. In this case, the carpet that is above it will be wet. And the degree of humidity depends directly on how strong the leak in the radiator. It is also possible to reduce the heat level from the heater radiator. The reason is that filling the honeycombs to the end does not happen, so the heating of the radiator grill is weak. And, of course, from time to time you will add the liquid to the expansion tank. It will gradually disappear, while in the under-hood space there will be no visible leaks. But do not rush to sin immediately on the radiator stove VAZ, first you need to make sure that it really broke down. To do this, carefully inspect the nipples with which it is connected to the cooling system. It is possible that a crack appeared on them, and the liquid leaves through it. It is also possible to destroy the crane, which is located in the partition between the cabin and the engine compartment.

Preparation for work

So, it is decided, we remove the radiator of the stove VAZ 2109, as we ascertained that the radiator is actually broken. You can start repairing. To make it as quick and safe as possible, first disconnect the battery. Then remove the motor protection, if any. Your task is to completely drain the liquid from the cooling system. To do this, you should put the car in such a way that its front part is slightly lower than the rear. Then completely open the stove cock. Do not forget to do this to get rid of the liquid to the maximum. Now you need to cover the generator with a piece of rubber or a bag so that no liquid gets on its back. Place a container under the radiator drain hole and unscrew the plug. After this you need to unscrew the plug on the tank. When the liquid drains out of the radiator, use a 13-key to unscrew the plug on the engine. The entire antifreeze also drains from the shirt. That's all, now the entire heating and cooling system is empty. Now we change the radiator of the stove VAZ 2109.

Replacing the heater radiator

The main thing in this work is to follow a certain sequence. The whole procedure will take a little time. True, there are two ways in which the removal and installation of a new radiator is made. First of all, as you understand, the coolant is drained. After that, the dashboard is completely dismantled. Then, the self-tapping screw turns off, which fastens the clamp of the linkage, connected to the damper to activate the windscreen. The three bolts that secure the radiator must be unscrewed. Loosen the clamps that securing the nozzles and remove them. Now the radiator of the stove VAZ 2109 (its price is in the range of 450-750 rubles) can be completely removed from the heater housing. This method of replacement is quite complicated, since you have to completely remove the entire panel. And this procedure is very complicated, since there are many points of attachment of plastic elements. In addition, the panel could have been previously treated with special compounds that reduce the noise level. After a complete disassembly, it is possible that the quality of the connections will be disrupted.

Replacing the radiator without removing the panel

For this reason, many are trying to replace the radiator without a complete removal on the dashboard. To make it much easier, than in the previous case. True, it is desirable to do the work together. So, you perform all the actions that were described in the section on preparation for repair. Please note that you need to clean the rubber mat during the work. Instead, it is desirable to lay a few rags, as the radiator stove VAZ 2109 (the price of a new average of 500 rubles) is still not completely freed from the liquid, a little bit left in it. And during the dismantling, she will start to leave it. Let it get better on rags, rather than on carpet. Then it is necessary to unscrew the panel fastening to the right side of the body. Also twist a few screws that are under the glove box. Your task is one goal - to ensure a free movement of the right side of the panel. After this, it is necessary to slightly lift it and pull it away from the partition. Thus you open access to the installation site of the radiator. By analogy with the last instruction, it is necessary to unscrew the clamps. After that, the nozzles are removed. All fastenings of a radiator are twisted. Now the element can be completely removed from the heater of the passenger compartment. Here's how to change the radiator of the stove to VAZ 2109 without completely removing the panel.

Radiator installation and assembly

After the dismantling is complete, a new radiator must be installed in the heater hole. Please note that it is advisable to purchase a copper radiator for the VAZ 2109. It has a much higher heat output. Of course, it is much faster heated by the cooling liquid. Wrap the three bolts that secure the radiator to the heater housing. Then put on the nipples and tighten the clamps. Assemble the dashboard and tighten all fasteners.

Refueling

After you do all the work, you need to wrap the hole to drain the liquid. Be sure to do this, otherwise the antifreeze will pour out. As you know, in cars VAZ 2109 and similar cooling system is filled with antifreeze through the tank. To do this, open the cork and fill the antifreeze. It should be poured until air bubbles cease to exit. Pay attention to the fact that the car is best set so that its front end is at a level higher than the rear. Here's how to change the radiator of the stove to VAZ 2109 to achieve the minimum air content in the system after refueling.

Air congestion

Thus, it is possible to fill the radiator of the stove as much as possible while refueling with liquid. Loosen the clamp on the clamp, which is fastened to the nozzle, which goes to the throttle. From there, liquid must be poured. True, you need to create pressure in the cooling system for this. This can be done by pumping air into the expansion tank. Either close the plug and start the engine, warming it to the operating temperature. Now you know how to change the radiator of the stove to VAZ 2109. The work is simple, but it will require you to be diligent and patient.
