Despite the fact that VAZs can hardly be called ideal cars, their popularity is growing every year. One of the obvious disadvantages of the VAZ-2101 is the stove. It slowly warms up the interior, causing the windows to remain foggy for a long time. It is uncomfortable and cold to be in the car at this time. But if there is a desire, this drawback can be, if not eliminated, then minimized. Modification of the VAZ-2101 stove with your own hands can be done in at least three ways.
VAZ-2101 is one of the most popular domestic cars in our country
Replacing the heater radiator Lada 2101 (VAZ 2101)
Removing the heater radiator on a VAZ 2101-2107 and those models between (2102, 2103, 2104, 2105 and 2106) is not as difficult as it might seem at first glance, the only thing you need is to stock up on antifreeze or antifreeze, depending on what is filled.
I removed the heater radiator for the first time for a trivial reason: the heater tap was leaking. Replacing it involves removing the radiator completely.
Also, the reasons for removing the radiator may be due to the fact that the stove does not heat well, as was the case for me.
And it is possible that the radiator itself may leak, as my friend had, then you will have to buy a new radiator (preferably copper).
And these are the main reasons when it is necessary to remove the heater radiator on a VAZ classic.
Now let’s look at how to remove the heater radiator using the example of VAZ 2105 and 2107 (on other VAZ cars, the process is similar).
Refinement using a new snail
To radically change the airflow of the stove and make it quieter, you can install a snail from the VAZ-2108 on the VAZ-2101.
What to buy
To do this you will need:
- New airflow mode switch.
- Resistance from a VAZ-2108 car.
- Snail from VAZ-2108.
- Wires, bolts, nuts, aluminum or any other corners.
- Thick plexiglass for the box.
- Industrial hair dryer to bend plexiglass.
Work step by step
As a result, we will get an improvement in all heating indicators - the cabin will be warm, and the most pleasant thing is that the noise will be significantly reduced.
- We make a housing for attaching the “snail” from plexiglass. That is, we cut it, bend it with a hair dryer, getting the desired shape. To reduce the size of the case, you can cut off the snail plugs.
- The side walls can be made of duralumin (1.5 mm thick). If cracks or crevices appear in the joints during work, they should be sealed with silicone sealant.
- We make collapsible air channels through which the flow will go to the air duct openings.
- Turns must be made smoothly to reduce air resistance in the flow and direct the air straight.
- If you want to bring airflow to your feet, make slots with flaps in the right places. If desired, you can install a variable resistor for adjusting the speed of the cochlea instead of the backlight brightness resistor.
If you do everything correctly, you will get a stove that operates almost silently, especially at low speeds. Despite the large number of bends in the design, the air flows will be sufficient to quickly heat the interior, and the second and third speeds can be turned on only in emergency cases - when you need to heat the interior very quickly.
Therefore, if you are not satisfied with something in the VAZ heating system, try to modify it. And you will succeed!

Signs of a malfunction of the VAZ 2107 heater radiator
A malfunction of the heater radiator can be due to two reasons:
- Coolant leakage from the radiator.
- Clogged internal channels.
It is necessary to remove the radiator of the VAZ 2107 cooling system; if any of these problems are detected, after dismantling it is repaired or replaced with a new one. The replacement process itself is not very complicated; you need to be careful and careful. To replace the heater radiator you will need the following tools:
- Key to 7;
- Key for 10;
- Crosshead screwdriver;
- Rags;
- Coolant;
- two new rubber gaskets.
The stove doesn't heat
If the engine is warm, the heater valve is open, but cold air is coming from the heating system, then most likely the radiator is clogged or there is a low level of antifreeze in the cooling system. To check the coolant level, just look at the level in the expansion tank or unscrew the main radiator cap with the engine off. If there are no problems with the level, then you need to deal with the heat exchanger, you may have to flush it or the entire cooling system. To avoid possible clogging of the heater radiator, you should not add various additives that eliminate small leaks. Such products can easily clog the stove tubes.
Cold air flow from the heating system can also be caused by air in the system. In this case, you will need to remove the air plug and add coolant.
Airing is the appearance of an air lock in the cooling system during repair work or when replacing the coolant.
In addition, the problem is possible with the tap itself, which over time can become clogged or scale may form if water is used instead of antifreeze. If there is a problem with the tap, the part is disassembled and cleaned or simply replaced. Another, although rare, but possible cause of a cold stove, may be pump failure. In this case, the engine warms up, but the pipes going to the heater radiator remain cold. In this case, the water pump must be repaired immediately. Warm air may also not enter the cabin due to problems with the heater fan. The problem may be with the motor itself or its power circuit, for example, if a fuse blows.
Self service
Using the diagram, it is easy to ring the wiring and identify the cause of the breakdown:
The technical manual supplied with the car clearly shows:
Conclusions: the VAZ 2103 car turned out to be not only beautiful and elegant, but also technically more advanced. And the care of car owners and independent maintenance had a positive impact on its longevity. Watch the video that VAZ 2103 owners boast about and you will see for yourself.

Simple rules that, if followed, will extend the life of the heater radiator
In order for the radiator to last a long time, you need to follow a number of rules:
- When purchasing, you should not save money and buy a low-quality unit. You should pay attention to the material of manufacture and the manufacturer.
- Only high-quality liquids should be poured into the system. Do not pour water and mix antifreeze with antifreeze. No lubricant or fuel should enter the system.
- When idle during the warm season, when the heater is not in use, you need to open the heater tap at least twice a month so that liquid enters the radiator. Thus, the unit will not dry out and the heater tap will not stick.
If you carefully operate the heating system and fill it with high-quality antifreeze or antifreeze, then its components will last for many years.
Self-tuning of the dashboard
Once released, the dashboard is covered with flock or faux leather. This will make her more attractive. It is carefully cleaned, coated with Moment glue, onto which the leatherette is attached, the material is smoothed, after which the panel is left for a while to allow the glue to dry.
Using a felt circle cut out for the edging of the dials will give the LED backlight a vibrant look. Holes are cut in the panel for the measuring sensors, all excess is removed, then the sensors are inserted and connected to the existing wires.
Replacement procedure
You can buy a new heater radiator for a VAZ 2107 at any auto store; an aluminum one will cost about 1 thousand rubles, and a copper one will cost a little more, but it can be soldered, which, however, is only a temporary measure. The kit should include spare parts necessary for installation.
First you need to disconnect the battery terminal so as not to damage the car's electrical system during operation. Radiator installation begins with draining the coolant. To do this, use a 13mm head to unscrew the drain plug, which is located on the cylinder block; there is no need to drain the cooling system radiator.
