How to remove the stove of a VAZ 2101 tnvd-auto.ru

An additional heater is not installed on all modifications of the Volkswagen Sharan. Its normal place is above the rear left wheel arch. At the left threshold there are pipelines that supply hot antifreeze to the radiator. An additional electric motor is used to regulate the supply of warm air.

The main difference between the second stove and the main one is that it operates in recirculation mode: interior air is used for heating, not outside air. On modifications with a diesel engine, an additional antifreeze heater can be installed, since the operating temperature of the coolant here is lower than that of gasoline versions.

How to improve the VAZ-2101 stove with your own hands: three ways

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.

Main malfunctions of the VAZ 2110 heater

Ten, although old, is a good and simple, repairable machine. At the same time, it is quite inexpensive. It has never gone beyond the sacred club of “everyone under 500” and will never come out again, therefore it is doomed to popularity on the secondary market. The car has a number of childhood diseases that have become chronic in nearly 18 years of production. But the clinical picture of each case has been studied in detail, therefore, in the case of the stove and its main components, each breakdown has a reliable and proven repair algorithm. The VAZ 2110 heater, in principle, was designed theoretically well and at the time when the car had just begun to come off the assembly line, it was not yet the most primitive in the world.

What does the stove consist of?

Before you start improving the stove, you need to understand what elements it consists of. Any VAZ stove consists of:

radiator;
air flow distributor;
three-blade or 5-blade fan and its shell.

If the theater begins with a hanger, then the stove begins with an air intake duct. It is located at the rear of the engine block. It is here that the air coming from the street is purified from moisture. The box is protected from a hot engine by special gaskets - they act as a partition.

After the air is cleared of moisture, it enters the heating system. The steam then comes out. There is a device above the dashboard that allows some of the air to escape when driving.

The heating housing is located in the interior of the car: it is fixed to the partition with the engine.

The heater radiator has inlet and outlet channels. These channels are connected to each other by tubes. The first tube has a built-in heating valve that regulates the supply of cooling liquid. Using a lever located on the dashboard, the flow of fluid into the machine's ventilation system is reduced or increased.

At the bottom of the radiator there is a heating system fan with a small motor that allows you to adjust the fan speed (there are two speeds in total).

The exhaust device allows the incoming air to be distributed throughout the cabin.

In order for the improvement of the VAZ-2101 stove to be justified, it is necessary to understand why the stove is not working well. If you are satisfied with your car, the stove is working properly, but you want to improve its performance, then it’s time to do tuning.

What to do in case of depressurization

If there is a flood in the cabin, then first of all you need to move the crane control handle to the extreme left position. This will save you from scalding, engine overheating and the need to take an additional bucket of antifreeze. If the valve is closed, but coolant flows out from under the torpedo, it means that the supply pipes, hoses, or the valve itself have burst. Here you urgently need to brake, turn off the engine and either take the car to a service center, or get the necessary tools from the trunk and start repairing.

Refinement by sealing joints

The first method is the simplest, but it will not bring big changes to the interior temperature. It consists of sealing the air outlets, so that air will flow better into the cabin.

This will allow you to optimally adjust the air flow, and the windows will be cleared of steam and icing faster. Sealing all existing connections helps to avoid unnecessary air loss, but this does not make the car any warmer.

If this modification is not enough for you, then it’s time to take the bull by the horns and tune the entire stove. It may sound scary, but in fact, modernization is not as difficult as it might initially seem.

Improvement by replacing the fan

Since the radiator in a VAZ gives off a sufficient amount of heat, poor interior heating is associated with deficiencies in the fan. Simply put, there is not enough air to heat the entire interior of the car.

To solve this problem, it is worth replacing your fan, which is too small and not productive, with a better fan - from a VAZ-2108 or VAZ-2109, which have a higher rotation speed.

Refinement of the VAZ-2101 stove is carried out in several steps.

Step-by-step instruction

In the cabin, we remove the shell of the lower part of the heating, where the fan is located.
We remove, in fact, the fan, which we will no longer need.
If you install a part from a figure eight, you need to cut the ridge that supplies air to the floor of the car.
We remove the fan with two blades, since a fan with five blades will work instead.
Don’t forget to check the new fan before installation - connect it and see if the blades move and there is air flow.
We fix the new device instead of the old one and securely fasten the entire structure.
Along with the fan, it is worth reinstalling the resistor, buttons and regulators - we also take them from the figure eight. This must be done, since due to the difference in currents the elements will quickly become unusable.

Tuning the VAZ-2101 stove, based on replacing the fan and other elements, although it will not make the stove work quieter, will allow it to heat the interior faster and better.

Dismantling the heater and radiator of a new type

Unification and simplification of life for owners is not for VAZ cars. The stove radiator has survived two revisions. The most successful and easiest to dismantle is the last one. In order to remove the new type of heater core, you just had to follow the algorithm. There was no element of creativity, but the part was removed quickly and using technology:

Drain the antifreeze.
Unscrew the central bolt at the lower edge of the windshield under the hood, where the windshield washer hose passes.
Unscrew the nut on the left near the filter.
Remove the air filter.

Then the heater body will split into two halves, after which all that remains is to loosen the clamps, remove the leaking or clogged radiator and replace it with a new one.

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!

How to remove an old-style heater, video

Everything is more complicated here. We had to disassemble half of the car under the hood and remove the front panel in the cabin. The operation could take several days if you don’t use your wits. The standard dismantling procedure looks like the video that shows how to remove the heater radiator on a VAZ 2110.

Long and hard. There is another way, but it involves dismantling the front panel, and this is not any faster. But the main thing that needs to be learned, given the complexity of the work, is that antifreeze leakage may not necessarily be in the radiator honeycombs. Heater hoses may crack due to material aging, but even to replace them, you will have to carry out a rather lengthy procedure for dismantling the casings and filters. And also, if the radiator is copper, and it is definitely damaged, then you should not throw it away, since it is soldered perfectly and lasts longer than aluminum.

Good luck and patience in the fight against the stove radiator, don’t delay replacing it and don’t wait for frost. Warm and kind travels to everyone!

Removing and replacing the stove on a VAZ car 21099

Device on the dashboard

It happens that you open the door of your own car, sit in the driver's seat, insert the key into the ignition, start it, and liquid begins to drip from under the center panel. And when it doesn’t just drip, it pours. If you are an inexperienced car owner, you immediately wonder what happened. If you have a lot of experience, then you understand perfectly well that the heating system of the cabin has become depressurized. Let's look at how to remove parts of the VAZ 21099 stove without the help of professionals for diagnostics, repair, and, for you, replacement.

First, let's study the structure of this device. Stove for VAZ 2108- 21099

located under the central panel, between the torpedo and the engine shield.
Attaches with 4 bolts to the air supply box. Consists of 2 plastic casings - left and right. The heater radiator is located inside the casings. It consists of 2 rows of tubes, heat exchange plates and 2 plastic tanks, secured with 3 screws to the right casing. An electric fan is mounted on top of the heater; it is needed to pump air into the cabin. It is natural to remove the unfamiliar engine department. There is also a stove faucet - a miracle device that allows you to keep hot antifreeze out of the heater, as well as faucet rods and pipes.

Replacing the stove on a VAZ-2101, 2102, 2105, 2106, 2107

Most often, a malfunction of the heater radiator is detected when a puddle of antifreeze or water forms under the feet of the driver or front passenger, or when you turn on the heater in winter, instead of warm air, you get a stream of cold air, and again a puddle of antifreeze in the cabin.

The reason for this is a leak in the car's heating system. The result of such a malfunction is a spoiled mood and cool temperature in the cabin. This problem can be easily corrected on your own. For some VAZ models it will take very little time - VAZ-2101, VAZ-2102. Replacing the stove in a VAZ-2105, 2106, 2107 will require more fuss; repairing the heating system on these cars is not much different, but things are a little more complicated with the radio panel. In this article you will find useful information and guidance on replacing the heater radiator of VAZ cars.

Heater radiator diseases

The heater radiator on the ten was hidden under a million panels, housings and partitions, so it was extremely difficult to get to it. And it was necessary to get there for several reasons:

The heat exchanger was constantly clogged from the outside. The thin cabin filter did not catch small dust particles, which gradually settled in the radiator honeycombs. Some owners even abandoned such a cheap consumable item as a cabin filter, and then not only dust settled in the radiator, but also any debris that the car sucked up like a vacuum cleaner.
The heater radiator was clogged from the inside. As a rule, this happened due to the desire to save on coolant. Then all sorts of “antifreeze” in quotation marks was poured into the cooling system, which was an incredibly useless and often downright harmful substance of a delicate blue color. At best, it was high-quality natural tap water, colored either blue, which is not so bad, or vitriol, which looks really disgusting. The result is scale, corrosion and cavitation.
The quality of the radiators also left much to be desired. DAAZ radiators worked tolerably, because the company had been supplying spare parts to the assembly line for a thousand years, but new and unknown companies soldered and welded radiators extremely poorly and from poor materials. Hence the constant leaks of even new radiators, the places where the rubber pipes were attached were cracked.

Therefore, the radiator often required replacement.

Replacing the heater radiator on a VAZ-2101, VAZ-2102, VAZ-2106, VAZ-2107 car

Motorists often remember about the heater radiator only when the autumn-winter period begins. No, there are times when they remember him earlier. For example, the unexpected appearance of antifreeze or water (depending on what is poured into the cooling system) under the feet of the driver or front passenger. The reason for this phenomenon is a leak in the car's heating system. But, most often, the driver learns about the malfunction of the heater radiator only when cold weather sets in. When you want warmth and comfort in the car interior. You pull the heater switch knob towards “heat”, turn on the fan and suddenly, instead of a warm flow of air from the air ducts, you get a flow of cool air or another option – the formation of a puddle of antifreeze in the car’s interior. And as a result, a spoiled mood and a cool, uncomfortable environment in the car.

But, everything can be fixed (for any car) and quite in a short period of time (this is said about the VAZ-2101 and VAZ-2102 ). In principle, replacing the heater radiator and other troubleshooting of the heating system on other Zhiguli - VAZ-2105, VAZ-2106, VAZ-2107 - is not much different, a little more fiddling with the radio panel (bar), but this article will describe the process repair of the heating system and replacement of the heater radiator on the VAZ-2101, VAZ-2102.

Causes of heating system malfunction:

The cause of an antifreeze leak in the car interior may be a rusted heater radiator or a metal pipe or heater tap . The exact cause can be determined by visual inspection. If the whole “trouble” lies, for example, in the stove tap or pipe, then they can be replaced without disassembling the radiator casing and the “Bar” panels. If the culprit of the coolant leak is the radiator itself, then there are two options for solving the problem. First, if you have a copper radiator (an old model), it can be repaired - cleaned, soldered, tinned, etc. The main thing is to find a specialist - a radiator technician. The second option is that you have an aluminum heater radiator . Everything is simpler here, it is better to replace it with a new one, it cannot be repaired.
When the heater is turned on, cold air continues to blow from the air ducts. The reason is a violation of the circulation of coolant in the car system, due to the fault of a non-working heater tap (it is constantly closed) or the radiator itself is “clogged”. If the faucet is jammed, it should be replaced, but point “1” of this article will help us choose the right solution for the radiator (see above).

Low panel

In general, replacing a low panel is not much different from replacing a high one. The actions in both cases are approximately the same. However, in the first case, it should take a little less time. The fact is that you can change the heater radiator without removing the passenger seat. Disassembling the chair also takes time, so it is not lost. It is important here to remove the steering wheel cover so that it does not get damaged when removing the panel. After finishing, it is very important to wash your hands well, since during work they get exposed to coolant, which is hazardous to health. If possible, work should be done with gloves so that various liquids do not damage your hands.

So, we have looked in general terms at how to properly remove a radiator and the subtleties when working with high and low panels. If you have the appropriate knowledge, performing this work will not be difficult. But if you are not confident in your abilities, contact a technical service, where they will not only qualitatively replace the heating device, but also the switch, as well as other elements of the VAZ- 2109 . You will have to pay for such a service, but the result will be the best.
