After replacing, be sure to check for leaks from the radiator, as well as on all connections.
Another, rather common "disease" of the VAZ 2110 associated with the stove, is that it works very noisily. This does not interfere so much with the arrival of heat into the salon, as it is annoying, and you wait: something is about to break.

The main reasons for replacing the stove radiator are : leakage of the heater radiator and a decrease (or complete absence) of heat transfer from the radiator. With the first reason, everything is clear and understandable. The loss of antifreeze from the expansion tank and traces of its (antifreeze) appearance under the car are hard not to notice. Plus, on top of that, the smell of antifreeze will appear in the passenger compartment. And the diagnosis suggests itself - the radiator of the stove dripped. But with the second reason, everything is not so fast and clear. Since a decrease in the temperature of the air entering through the heater into the car interior can occur for several reasons - an insufficient level of coolant in the car system, a faulty thermostat, an air lock in the cooling system, a problem with the regulator or motor for controlling the stove damper and, finally, clogged stove radiator ... Therefore, before “blaming” the stove radiator for weak interior heating, you must first check and make sure that the entire cooling / heating system is working properly (check the antifreeze level in the tank, check the thermostat, make sure the unit and the heater flap control motor are in good working order).
Only after that it will be possible to sign the final “verdict” for the stove radiator. But, before that, it will not be superfluous to carry out one not tricky check: we warm up the engine to operating temperature, in the engine compartment we check the upper and lower pipes of the stove by hand (they must be of the same temperature), turn the “heat-cold” knob all the way to the right, turn on heater fan.If, in the first 10-20 seconds, the air flow was hot or comfortably warm, and after that its temperature began to noticeably decrease to “room temperature”, then you can safely prepare to work on replacing the stove radiator. And this photo report with a description the fastest way to replace the radiator of a new type of stove on VAZ 2110-2112 cars will be useful to you. As a last resort, I hope so))).
Spare parts. For cars Vaz 2110-2112 stove radiators are sold in two versions - old and new ... Until the fall of 2003, dozens of old-style heater radiators were installed. After 2003 - a new one. These radiators are not interchangeable. Therefore, before going to the car market, you must first decide which of the two options you should buy. Catalog number of the radiator of the stove of the new sample - 21110-8101060-00 ... The catalog number of the old-style stove radiator is 2110-8101050 .
Then they answer the question - “Which manufacturer of a stove radiator is better to buy / put on a VAZ 2110? “. The correct choice of a stove radiator (heater) for Vaz-2110, Vaz-2111, Vaz-2112 - radiator produced by DAAZ ! And this is not an advertisement, but friendly advice. Excellent quality and excellent heat dissipation - time-tested. All other options will definitely lose. Or they will flow quickly, or they will warm up weakly. Therefore, I recommend not to play roulette and not to try to save money, but to buy a DAAZ stove radiator.
List of tools that will be needed for the successful replacement of a new type of heater (stove) radiator on Vaz-2110, Vaz-2111, Vaz-2112 vehicles produced after 2003 : a container for collecting coolant, a Phillips screwdriver, a high head for 10 + a ratchet wrench, a socket wrench for 17 and 13 (the presence of a cardan, an extension and a ratchet wrench is welcome, since their presence greatly facilitates and speeds up the work).
Photo report describing a quick way to replace a radiator of a new type of stove (after 2003) on cars Vaz-2110, Vaz-2111, Vaz-2112:
The first step is to drain the coolant. We find the drain plug on the engine block (photo 1). We substitute a container for collecting antifreeze under the engine and unscrew the plug (key for 13). Then we unscrew the cap of the expansion tank. While the liquid is draining, we begin disassembly.
If you have made a decision or there is a need to replace the coolant together with the stove radiator, then you will have to drain the antifreeze from the cooling radiator (photo 2)
We unscrew the clamps and disconnect the pipes from the expansion tank. We unfasten the fastening strap and remove the expansion tank (photo 3).
Remove the bonnet seal (photo 4).
We find and unscrew all the fastening screws of the left and right parts of the soundproofing sheathing of the engine compartment (photo 5, 6, 7, 8).
Disconnect the plastic clamps from the casing (photo 9).
In the lower part, the trim is attached to the car body with two nuts. We find them and, using a high head 10 and a ratchet wrench, unscrew them (photos 10 and 11).
After that, you can pull out the trim from the engine compartment.
Disconnect the chip from the brake cylinder reservoir cover (photo 12).
Disconnect the hose together with the fitting from the vacuum booster (photo 13).
Using a 17 key, unscrew the two GTZ fastening nuts to the vacuum brake booster (photos 14 and 15). In order not to air the brake system, do not unscrew the tubes from the master brake cylinder. It is enough to take the GTZ forward (in the direction of the vehicle's movement) as far as the brake pipes allow.
We climb into the car. Disconnect the wires from the brake light switch (photo 16).
Using a 13 socket wrench, unscrew the four fastening nuts of the brake pedal bracket to the body (photos 17 and 18).
After that, you can return to the engine compartment and start pulling out the vacuum brake booster along with the bracket and pedal. This is not an easy task and it is unlikely to be able to be pulled out quickly. You have to twist and turn the vacuum booster a little before you can pull it out.But, I can assure you to pull out the vacuum amplifier with the bracket is quite possible without removing the plastic cover of the windshield (photo 19).
Everything is now access to the heating radiator (stove) of the new design is open. Where the stove radiator is located on the VAZ 2110-2112 can be seen in photo 20.
It remains only to unscrew the worm clamps of the two main and one steam outlet pipes (photo 21). Disconnect the connector from the damper control micromotor (photo 22).
And unscrew the three fastening screws of the radiator to the stove body (photo 23).
We take out the old radiator (photo 24).
We clean the niche of leaves and debris. And we install a new stove radiator (photo 25).
Just as fun as we pulled it out, we return the vacuum brake booster with the pedal bracket to its place (photo 26).
After that, the assembly is carried out in the reverse order.
That's it! The replacement of the radiator for the stove of a new type on the cars Vaz-2110, Vaz-2111, Vaz-2112 has been completed.
Stove VAZ 2110 perhaps the most problematic and capricious mechanism in the entire car design. You can't do without a stove or a faulty interior heater radiator on a VAZ 2110, given our cold climate. If in the summer a non-working stove may not bother you, then with the onset of the cold season it often turns out that the stove on the VAZ-2110 is blowing cold air. Today we will try to tell you in great detail about the device, repair and replacement of the heater on the top ten. For clarity, we will supplement the text with photos and videos.
Let's say right away that the design of the heating system on the “top ten” is fundamentally different from what was on the old VAZ models. The most important feature and difference between the interior heater is that stove radiator VAZ 2110 and its fan is not in the passenger compartment, but in the engine compartment. This design has its advantages, for example, to replace the heater radiator or stove fan, you do not need to completely disassemble the front panel (dashboard).
Another important difference is the electronic control of climate processes in the cabin. For this, the so-called automatic heater control system (SAUO). Photo of the SAUO block below.
By the way, the SAUO unit on the “dozens” of different years of manufacture is different. Since 1996, 4 types of SAUO controller have been produced. This should be taken into account when buying a unit as a spare part. It is this device that controls the temperature in the cabin and the operation of the fan. The temperature can be set from 16 to 28 degrees.
But how does this miracle device work? There is a temperature sensor or a ceiling air sensor with a built-in (very small) fan for air circulation on the ceiling of the “dozens” cabin. It is this sensor that sends information about the real temperature in the cabin, and the SAUO unit gives a command to the micro gear motor (MMP), which, in turn, opens or closes the main damper, which is responsible for the access of hot air to the cabin. When the temperature in the passenger compartment changes, the ceiling sensor gives a new signal, the micro geared motor is triggered by turning the damper, closing or opening the hot air access to the passenger compartment. Thus, the set temperature regime is automatically maintained. Further photo of the diagram of the air ducts of the VAZ 2110 heater .
Many owners of "ten" complain that at some point the stove constantly blows cold air and no turning of the handles of the automatic heater control system can save the situation in any way. There can be a lot of problems and malfunctions. For example, the SAUO controller itself, the ceiling sensor or the micro gear motor, which simply does not open or close the damper, is faulty. Another reason is the air (airlock) in the heater radiator, which is simply not able to heat the air passing through it. Further a schematic representation of a VAZ 2110 heater device .
Often the reason for the poor performance of the heater "tens" is stove damper vaz 2110 ... The flap may not close tightly or open well.The heater flap itself is made of plastic, which can deform over time and work poorly. Many car owners buy a metal flap and change it on their own. How to check the performance and assess the condition of the stove damper? Quite simply, remove the central air duct deflector and here it is! We look at the photo.
Then you carefully examine the damper, turn on the stove, turn the regulators on the SAUO unit and see if the damper works at all. How does it move, whether it fits snugly. If she does not respond to commands, then the problem may not be in her at all. For one thing, you can see if the lever for redirecting the airflow from the glass to the legs works.
It is quite simple to determine the operability of the stove fan by noise. If the fan motor burns out, then naturally it will no longer work. True, before rushing to change the stove fan, you must make sure that the fuse has not blown. As we wrote above stove fan VAZ 2110 located not in the cabin, but in the engine compartment. To get to it, you will need to remove a special apron that separates the engine compartment from the heater housing, the vacuum brake booster and the wiper mechanism. The photo itself is below for clarity.
So we got to the stove fan, removing the apron and the heater cover. By the way, next to you you will see a cabin filter, in the casing a little to the left. It must be pulled out and cleaned. If no one has changed the filter before you, for many years of operation it is seriously clogged with debris and interferes with normal air circulation, which is sucked into the VAZ 2110 interior.
The radiator of the “dozens” stove is located in the same place as the fan, that is, under the hood (see photo above). To remove it, you must first remove the fan from the heater casing. If you notice a strange smell in the cabin, lift the rugs, if there are puddles of antifreeze or antifreeze, then stove radiator VAZ 2110 drip. Although they may no longer hold the clamps ... in any case, you will have to disassemble and find out the cause of the leak. Next, we offer a couple of video clips demonstrating the process of disassembling, removing the apron, stove fan, cabin filter and heater radiator.

By the way, when replacing the heater stove, you can use the opportunity to replace and cabin filter VAZ 2110 , so that later it would not be disassembled all over again. This will help you feel the fresh air and warmth of the repaired VAZ 2110 stove in the cabin.
