We study the design and procedure for replacing the stove in a VAZ 2106 car

Types of systems

To upgrade your VAZ-2106 car and its heater with your own hands, you can choose one of three current methods.
They are used quite actively and make it possible to increase the level of comfort inside the interior of domestic classics. Additional electric heater. This is a device for heating the interior, which is quite simple and elementary in terms of use and installation. Electric heaters operate by connecting to the cigarette lighter on the front panel. To complete the installation, no special skills are required, since the heater starts working immediately after connection. However, this is an electric unit that will take energy. When operating at maximum speed, the battery will quickly drain. So, when the engine is not running, you should not use such a device. In fact, this is an ordinary hair dryer with a heating element and a fan, which creates the effect of additional heating inside the VAZ-2106. Autonomous heaters. For the VAZ-2106, such devices are practically irrelevant. More often used for additional equipment of trucks, large minivans or vans. The heater receives power from fuel. It has an autonomous combustion chamber and exhaust system. The operation of the system does not depend on the car engine. The unit has complex installation and negatively affects fuel consumption. And buying an autonomous system will cost significantly more. Externally, it is a metal structure with a combustion chamber and the necessary electronics. Auxiliary radiators

To heat the interior, car owners, including the VAZ-2106, where the standard stove does not cope with its tasks, often pay attention to additional radiators. The connection is made through the standard cooling system and stove.

What to wash with

The VAZ-2106 has standard and widely used radiators that do not impose special requirements on the composition or quality of the flushes used. You can use the same products that are widely used in other cars when cleaning radiators:

• two-component;
• acidic;
• alkaline;
• neutral.

Although among them, as experts note, the optimal choice would be a two-component mixture. An alternative to purchased formulations are folk solutions, which are quite simple and easy to prepare. Folk recipes are based on alkaline and acidic substances available in any home and grocery store. Namely:

• vinegar;
• soda;
• lemon acid.

In order not to harm the radiator of your VAZ-2106, be sure to use acids and alkalis alternately.

Device elements

The stove on the VAZ-2106 includes the following main components:

• deflectors;
• stove tap rods;
• air intake covers;
• windshield air ducts;
• radiator;
• radiator casing;
• outlet pipes;
• underwater;
• stove tap;
• air distributor cover;
• electric fan motor;
• fan impeller;
• additional resistors;
• air ducts of the internal ventilation system;
• distributor cap lever;
• brackets;
• lid control handle;
• crane control handle;
• draft of the air supply cover.

These elements represent a heater device on a VAZ-2106 car.

Design and operating principle

The cabin heater on the VAZ-2106 car is a compact unit, the main components of which include:

• stove motor;
• fan with impeller;
• radiator;
• damper for air flow distribution;
• stove faucet with control levers.

IMPORTANT! If leaks were found in the radiator circuit of the VAZ-2106 stove, then, if possible, replace the radiator with a new one. Its repair is complex, plus it does not always bring positive results.

This is more of a temporary measure.

The design of the stove on the VAZ-2106 car is quite simple, but for beginners, coping with the tasks of repairing it may be an impossible task. This is wrong. Especially if you are familiar with the device and design features of the heater.

1. The standard, that is, factory heater for the VAZ-2106, has a relatively compact size, but effectively cools the liquid and warms up the interior. This is noted by many owners of domestic classics. Switching on and control is intuitive.
2. The VAZ-2106 uses the most common heating system design among the Russian automobile industry, and in some places even the Soviet one. The basis is the liquid cooling system of the main engine.
3. The main elements of the heating system are the stove, connections to control elements (faucets, levers), lines and a radiator.
4. The heater dampers and valve are connected to the control device using an elastic and flexible rod.
5. When the upper element is moved to the upper limit position, the valve opens completely, which ensures the maximum amount of coolant entering the heating system through the radiator.
6. If the lower control device is moved to a similar position, then the air intake damper will be open to the limit. This way, maximum air flow will be directed through the stove into the heating system.
7. Deflectors made of plastic can change the airflow angle in the VAZ-2106 cabin. Thus, the driver and front passenger regulate the direction of the air flows created during heating or normal ventilation.
8. The air distribution cover is not connected to the heater control system switch. This damper allows you to adjust the degree of closing or opening using a lever device. This design provides additional comfort to the driver of the VAZ-2106 when regulating the operation of the heating system.
9. The device includes a three-position toggle switch designed to regulate the volume of air flow passing through the stove. The regulator allows you to choose between two ranges of rotation of the heater fan - from minimum to maximum.

IMPORTANT! Never turn on the electric heater fan if the air intake damper is in the retracted position and the valve is open

Features of connecting the stove

The VAZ-2106 uses the Me 255 electric motor. This is a direct current electric motor that is excited by a permanent magnet. Several nuances of the VAZ-2106 heater connection diagram:

1. When an additional resistor is connected to the electric motor supply circuit, the armature shaft begins to rotate, but at a lower frequency.
2. The resistor is secured with a pair of spring washers inside the heater fan casing.
3. At a temperature of 20 degrees, the resistor resistance is 1.5 ohms.
4. If the electric motor fails, it should be replaced;
5. Repair consists only of cleaning the commutator or applying lubricant to the bearings.
6. Normally, the nominal voltage parameters in the circuit are 1 V.
7. Rated power indicators - 2 W.
8. The rotational speed of the electric motor shaft is 3000 rpm (under 12 V voltage conditions).

The heating equipment is relatively simple in its design and design, which is why most VAZ-2106 car owners prefer to carry out repairs themselves.

Design and main malfunctions of VAZ stoves

The standard radiator of the VAZ 2106 stove, despite its small size, copes with its task of cooling the liquid and warming up the interior quite well. The design of the interior heater can be seen more clearly below.

The operating principle of this device is shown in the figure.

The “six” type of heating system is one of the most common designs based on the use of liquid from the cooling system of the power plant. It consists of three main components - the stove itself, the price of which is acceptable for Russian car enthusiasts, mounts with control devices in the form of taps and air ducts with a radiator.

The air intake damper and valve of the VAZ 2106 stove are connected to control devices using flexible and elastic rods. The maximum right position of the upper device means the maximum opening of the tap and the greatest flow of coolant through the radiator into the heating system. If the lower device occupies this position, then this means the maximum opening of the air intake damper, which directs the greatest air flow through the stove further into the heating system.

Plastic deflectors with a variable angle of airflow into the cabin make it possible to change the direction of air flow and direct it in the desired direction. Structurally, sometimes called the air flow distribution cover, it is not connected in any way to the system central stove control switch. This damper is adjusted to open and close using a lever device mounted for comfort on the driver's side of the seat.

The volume of air moved through the VAZ 2106 stove, a video about which can be watched on the Internet, is regulated by a three-position toggle switch. With this switch you can set 2 fan speed ranges, both the lowest and highest levels. It is strictly not recommended to start the electric heater fan with the air intake damper retracted and the tap in the “open” position.

The main defects of the VAZ 2106 stove include the following:

• defects in the stove motor, as a result of which it does not start;
• depressurization of the radiator heating system or pipelines, which is why the stove in the VAZ 2106 does not heat well and the cabin becomes cool;
• sometimes the stove blows cold when there is not enough coolant in the system, and if, when adding it to the norm, the defect is not eliminated, you need to cover the front part of the radiator of the cooling system with thick cardboard and the situation should improve.

Installing a motor from a chisel stove into a stock stove with modifications

I would like to bring to your attention my version of a modification of a classic stove. First, I will say that a serviceable Zhiguli heater copes with its task quite successfully, the car is warm even in severe frost, but at the same time it has a number of significant shortcomings that every classic car owner dreams of getting rid of. This includes strong annoying noise, insufficient airflow of the windshield and side windows, and a low number of heater fan speeds. It all started with the fact that a fifth assembled stove and an old chisel stove motor with an impeller ended up in my hands “completely free of charge.” This allowed me to experiment slowly while continuing to drive my car with the stock heater.

What is the best way to tune the VAZ 2106 stove?

There is a need to tune the VAZ-2106 stove due to its inability to cope with increased loads in cold or hot weather. There are many messages on thematic forums from drivers who are forced to wait almost 30 minutes for the oven to heat the air in the car at subzero temperatures. Increased consumption of resources and low efficiency of their use are the most common “stone in the garden” for equipment manufacturers.

Technical basis of modernization

The main goal of the planned transformations is to reduce noise and vibration pollution. Before starting work, you need to think about what exactly the driver wants to get at the end. The most common option is to increase the cold or warm air flow while necessarily reducing the level of noise pollution. To achieve this goal you will need:

• industrial hair dryer - used to give the required shape to plexiglass;
• several aluminum corners;
• screws;
• stove connecting elements;
• plexiglass, the thickness of which is 3 mm;
• “snail” from a VAZ-2108 passenger car - is responsible for reducing noise pollution and increasing air flow.

Initially, the “snail” body is created. It is advisable to avoid mistakes related to the parameters of the product, otherwise the stove will cause frequent visits to the service station. That is why the mounting socket is measured before starting work. Based on the collected parameters, plexiglass is cut. An industrial hair dryer is used to give the product the required geometric shape.

It is recommended to keep it at a safe distance, otherwise the plexiglass will be severely deformed. Practical experience shows that a good stove should be 2-3 cm smaller in size than the previous one. In this regard, it is necessary to carefully cut off the snail plug. If everything is done correctly, the parameters of the finished stove will eliminate the appearance of characteristic whistles and vibrations.

Increased attention is paid to the side walls. If they are too thick, this will negatively affect the air flow, but if on the contrary, the oven will actively vibrate

That is why duralumin is used as the starting material for them. The optimal thickness is 1.5 mm. At the next stage, the tightness of the structure is ensured. Silicone sealant is a proven tool for these purposes.

Practical results of transformations

Each crack is processed carefully, otherwise the air flow density from the stove will leave much to be desired.

The structure of the channels responsible for supplying air flow to the air duct and the turn signals are carefully studied. It is necessary to use material that allows you to solve several problems simultaneously.

Firstly, the air must move through the channel without increased resistance of the material. Secondly, the structure itself should not actively vibrate at times of increased loads. That is why the optimal material for forming air ducts is duralumin. After this, slots are created to air the driver and his feet.

From a practical point of view, the result of the work done is noticeable immediately. The reduction in noise pollution is significant. In second place is the increased power of air flow from the side slots. Despite the bends of the air channels, the airflow is significant. You no longer need to wait 20-25 minutes for the temperature in the cabin to reach the required level.

Step-by-step instructions for installing a new heater radiator

In order to correctly and accurately replace an old device that has ceased to function properly, first of all, as a rule, you should stock up on the necessary tools. In particular, if we are talking about replacing the radiator installed in the heating unit of a VAZ-2106 car, the car owner will only need a pair of keys (for “7” and “10”), as well as a screwdriver.

The first step is to open the stove faucet; this manipulation can be done by moving the control lever to the right side. Then you need to rid the engine cooling system of antifreeze.

Replacing the heater radiator on a VAZ-2106 car requires unbending the brackets that hold the vacuum hose. These small structural elements are located in the engine compartment, holding the wiring harness. Thanks to the fact that the motorist can move the hose with the harnesses to the side, it will be possible in the future to easily begin working directly with the heating unit.

Further actions should be aimed at loosening the clamps; after reducing the fastening force, all hoses can be removed from the system. After both bolts securing the seal are unscrewed, with which the front panel is held in place, the motorist will be able to remove the seal without much effort by carefully pulling it along the pipes

It is important to take into account one important detail, in particular the spacers. These small elements of the system are located inside the seal, so it is important not to lose them when removing them

The radiator of the VAZ-2106 stove can be upgraded only after removing the fan. It is worth noting that the unit should only be removed together with the machine casing. Immediately after this, you can begin to dismantle the heater radiator itself, carefully lowering the unit down to a level that will be directly determined by the control rod of the heater tap. When dismantling the device, it should be taken into account that the rear part of the radiator is lowered first, after which the pipes located in the niche of the front panel are removed.

The motorist must unscrew the bolt that holds the shell of the faucet control rod, and then remove the rod from the faucet itself. After this, not only the radiator can be removed from the vehicle, the faucet and pipes should be removed along with it. If you carefully unscrew a couple of bolts and remove the outlet pipe, you can quickly get rid of the gasket located on the pipe flange. After unscrewing the next two bolts, you should dismantle the faucet directly with the supply pipe.

The next thing to be removed is the gasket, which is fixed on the tap of the heating device. By unscrewing a couple more bolts, it will be possible to remove the supply pipe fixed to the heater faucet, so it will be necessary to rid the system of the gasket located on the supply pipe and faucet.

Before proceeding with replacing the main device, the motorist should first inspect both gaskets (on the inlet and outlet pipes). It should be remembered that these elements are interchangeable. In addition, the gaskets should not have any mechanical damage, and there should be no marks on them that hint at aging of the rubber. It is more expedient to replace these parts with new standard elements.

If the car owner was interested in how to remove the heater radiator on a VAZ-2106, then the described instructions, with the right approach, will allow you to do everything yourself in the shortest possible time. After dismantling, the car owner will only need to install a new radiator along with a faucet, in the reverse order described.

To make sure that their actions are correct, the motorist can check the heater radiator, in particular, by plugging all the holes in the device’s tank, supply air to it, which will have a pressure of at least 0.1 MPa. Then the unit should be placed in any container filled with water, and everything should be left there for at least 20–30 seconds. Any leaky place in the radiator with this approach will make itself felt by escaping air bubbles.

After a thorough check, it is necessary to position the rod shell, through which the stove faucet is controlled, in such a way that, when positioned in extreme positions, the adjustment handle can completely fix the opening or closing of the faucet.

At the end of the manipulation, you should fill the engine cooling system with antifreeze, check the tightness of the structure, as well as the functionality of the stove in the cabin.

Replacement of individual stove elements

Car enthusiasts often ask about the VAZ 2106 car, how to remove the stove for maintenance or service work. Such questions arise in connection with the need to repair the stove and subsequent assembly. To replace the heater radiator and heater tap, you need to prepare a set of plumbing tools and new spare parts for the heating system to be replaced:

1. Moving the lever to the right, open the heater tap, and then drain the coolant from the system.
2. In the mechanical compartment under the hood, unbend the fastening bracket for the vacuum type hose and the wiring kit that goes to the panel, put them aside so that you can get to the heating hoses.
3. We slightly unscrew the fasteners of the hoses to the heating radiator tubes and dismantle them.
4. We unscrew the 2 bolts securing the seal to the shield, and then slowly dismantle it, remembering that spacer-type bushings are installed there.
5. We dismantle the fan device of the stove.
6. We dismantle the heater radiator, leaving it hanging on the heater faucet rod and remove the tubes from the hole in the shield.
7. We unscrew the fasteners of the stove tap rod and disconnect it.
8. We remove the heater radiator from the “six” along with the pipes and the heater tap.
9. Having removed the fasteners, we remove the pipe from the heater radiator and the flange gasket from it.
10. Having removed the fasteners, remove the stove valve along with the gasket and the pipe from the heating radiator.
11. Having unscrewed the fasteners, we remove the pipe from the stove faucet along with the gasket.
12. If necessary, after a visual inspection of the gaskets, they must be replaced.
13. We are installing the stove.

If a car owner, in order to improve the functionality of the device, decides to modify the VAZ 2106 stove, then this will require its dismantling. The determining technological operation will be a change in the installation angle of the bulkheads with the preliminary production of updated configurations followed by installation.

All implementation of such operations will significantly change the direction of the air flow, and the stove will begin to operate with increased efficiency. To create such a “tuned” stove, you need a standard set of tools, as well as carpentry tools and a cutting torch to give the updated bulkheads the required configuration.

Modification of the carburetor and ignition system

In addition, it is impossible to imagine tuning a VAZ 2106 without modifying the carburetor. An increased engine volume with a reduced compression chamber will simply force you to increase the flow areas of the nozzles and the performance of the accelerator pump. The ignition system should not be ignored either.

If you decide to leave the stock one, check the stiffness of the springs in the ignition timing mechanism using a strobe light and, if necessary, adjust it to the factory values. Of course, it is best to install an electronic system. It will allow you to more accurately set the ignition timing and provide a powerful spark that will allow the engine to operate even in severe frost.

If you do at least half of the activities described above, you will see that modifying the VAZ 2106 engine with your own hands allows you to significantly increase its power.

The stove has lost efficiency - reasons

If the failure of one of the elements of the heating system is not difficult to diagnose, then it is often not easy to deal with cases of loss of efficiency on your own.

So, when the stove produces too little heat at maximum, then it is possible to suspect the following problems:

• blockage of the main or furnace radiator;
• wear of the air intake damper seal;
• cooling system malfunction.

We recommend starting your search for the problem with the heater radiator. For this:

• start the engine;
• warm it up to operating parameters;
• set the oven regulator to maximum;
• feel the radiator, as well as the pipes connected to the tap.

If the latter are both hot, then the heat exchanger is most likely clogged and will have to be cleaned or replaced. When the hoses are cold, there is a problem with the cooling system. Heating of only the pipe leading to the tap indicates that the latter is jammed or the traction cable is broken.

An abnormally high radiator temperature coupled with low heater efficiency indicates airflow problems. This is where the damper gasket most often fails.

Repair of heating radiator VAZ 2107

Often, repairing a VAZ 2107 stove involves replacing or repairing the heater radiator. Repair actions depend on the type and cause of the malfunction:

A clogged radiator can be flushed with water pressure. Scale on the walls of honeycombs can be removed using a special product that dissolves it.

A leak in a copper (brass) radiator can be soldered. Using a powerful soldering iron and solder, you can repair a hole or crack. Leaking aluminum radiators must be replaced.

Important: to eliminate a leak in the heater radiator or engine cooling system, you should not use products added to antifreeze - they can cause clogging of the VAZ 2107 radiator honeycomb.

Modification of the stove for the VAZ 2106 car

The heating device in the interior of the classic “six” must provide heat and work properly, otherwise the VAZ 2106 stove needs to be modified. The temperature inside the car must be comfortable not only for the passengers of the vehicle, but also for the driver, especially if he has to spend a long time driving time.

A significant part of VAZ 2106 cars are traditionally operated in fairly cool climatic conditions, when even in summer it can become sharply cold. The stove in classic models is well thought out and works, but small improvements to the heater or repair (or replacement) of the heater valve and/or radiator grille can significantly increase the heat transfer and functionality of this device.

Features of the heating equipment on the VAZ-2106

Problems with the stove on VAZ-2106 cars are not so common, since this unit is considered relatively reliable. But in some situations it is necessary to intervene in it, carrying out partial repairs or performing a full replacement of failed heater elements. To properly carry out repairs or replacements, you must first become familiar with the diagram and structure of the stove.

PROCEDURE FOR REPLACING THE VAZ 2106 HEATER

The vehicle interior is heated by engine coolant. The heater design details are shown in the diagram.

Many car enthusiasts only think about the heating system when it gets cold. But sometimes the heater can remind you of itself with an unpleasant smell in the cabin and the appearance of puddles of antifreeze under the feet of the driver or passenger in the front seat. This means that the heater core is leaking and needs to be replaced. This work can be done with your own hands.

To do this you will need:

1. open-end wrenches for 7 and 10;
2. flat and Phillips screwdriver;
3. Antifreeze supply is approximately 1.5 liters;

Replacing the heater radiator VAZ 2106

Open the heating valve and remove the vacuum hose and wiring harness

• Having moved the heater control lever to the right all the way, open the heating tap and drain the Antifreeze from the heater radiator;
• in the engine compartment, release the fastening of the vacuum hose and wiring harness and move them to the side, thereby providing access to the heater hoses;

Release the clamps, remove the hoses and gasket

• loosen the hose clamps and remove them from the pipes;
• then unscrew the two bolts that secure the seal to the shield;
• carefully remove the sealing gasket from the radiator pipes so as not to damage it;

PLEASE NOTE: THERE ARE TWO SPACE WASHERS INSERTED INTO THE GASKET, IT IS PREFERABLE NOT TO LOSE THEM. remove the electric heating fan together with the casing (how to dismantle the electric fan is described below);

Replacing the heater radiator on a VAZ 2106

We take out the radiator and remove the heating valve VAZ 2106

• we take out the heating radiator along with the tap, lower it down as far as possible and remove it along with the pipes;
• unscrew the bolts securing the outlet tube and disconnect the tap;

RECOMMENDATION: REMOVE ALL SEALING GASKETS, INSPECTION THE FLANGE CONNECTIONS, CLEAN THEM IF NECESSARY, INSPECTION THE ATTACHMENTS OF THE PIPE TO THE RADIATOR, IF THERE ARE SUSPECTS OF LACK OF TIGHTNESS, IT MUST BE ELIMINED IMMEDIATELY, REPLACEMENT IS MANDATORY REPLACE ALL GASKETS WITH NEW ones.

• install a heating tap on the new radiator, connect all the pipes;
• install the new radiator in the reverse order;
• set the heating tap control lever to the extreme right position and make sure that the tap is fully open, connect the tap control cable;
• Replenish the engine cooling system, start the engine and carefully check all connections for leaks.

Disconnect the motor mount

• turn the fan over and open the cover;
• press out the spring brackets that secure the electric motor and remove it;
• unscrew the nut and remove the impeller, as well as the rubber pads;
• We install the new electric motor in the reverse order.

After completing all the work, you need to add Antifreeze a little above the maximum level, start the engine, check all connections for leaks, the Antifreeze level should drop slightly due to the displacement of air from the heating system. Warm up the engine and turn on the interior heating. Check the flow of warm air through all air ducts. Approximate prices for repairing the heating and ventilation system in a car service center:

• replacement of the heater tap - 500 rubles;
• heater radiator replacement - from 800 rubles;
• replacement of a heating fan electric motor - from 500 rubles;
• Replacing a heating tap cable - 300 RUR.

To replace the heater on a VAZ 2106 at a car service center, you will have to pay approximately 2,500 rubles plus the cost of the replaced parts or components.
