VAZ 2107 heater tap and heating system as a whole - looking for breakdowns + video » AvtoNovator

The heater valve is used to regulate the flow of coolant through the radiator. In the warm season, there is no need to heat the interior, so the tap is most often in the closed position.

With the arrival of cold weather, we again remember the possibility of adjusting the temperature in the cabin, but sometimes we encounter unexpected problems: the heater tap (when liquid passes through it) can leak, oxidize and even jam (if not used for a long time). This part cannot be disassembled or repaired, so to restore the heating system, all that remains is to replace the stove tap .

Stove design

The stove consists of the following parts:

  1. Heater, a stove radiator is installed in it (indicated by the number 5 in the figure), it heats the air penetrating from outside;
  2. The stove fan, or motor (indicated by the number 14 in the figure), it pumps a flow of warm air into the cabin, it is mounted in a special casing (indicated by the number 16 in the figure) on elastic cushions that dampen its vibration;
  3. The stove control system is a fan button (indicated by the number 18 in the figure), three control knobs for heating modes - blowing onto the windows, taking air from the cabin or from the street, and opening and closing the stove tap.

1, 9 – air ducts for heating the side windows on the left and right; 2 — air duct for heating the windshield; 3 — radiator casing; 4 — air intake cover; 5 — heater radiator; 6 — radiator valve; 7, 8 radiator hoses for supplying and discharging hot fluid from the cooling system; 10 — rotary deflectors; 11 — air duct damper; 12 — air distribution cover; 13 — fan guide casing; 15 — lever of the air distribution cover; 17 — control rods; 19 - central air duct.

The heating system works in the following order:

  • Air for heating comes from outside, through air intakes on the hood.
  • Under the hood there is a special box, insulated with a rubber seal, for air flow.
  • From it the air flow is directed to the stove.
  • Next, the air is heated by a radiator, which is fed with antifreeze and antifreeze. The degree of heating is regulated by the heater tap. The faucet is controlled by a flexible rod using a control lever.
  • At high vehicle speeds, air can enter the passenger compartment without the fan being turned on. Therefore, at high speed you can use the stove without additional load on the car’s electrical network. The interior heater is turned on by a fan switch that has three positions - neutral and two speeds: low and high. Speeds are provided by a resistor; it increases the resistance of the circuit and reduces the speed of the fan.
  • The fan accelerates the warm air flow through the air ducts to the sides, onto the side windows for good visibility of the rear-view mirrors, and into the grille deflectors, which can change the direction of the air flow for better airflow. There is also a flow of warm air through the air duct to blow on the windshield.

Above in the figure, blue shows the circulation diagram of cold air flows, and orange shows the movement diagram of warm air flows. Main parts of the heating system:

1 — air distribution cover; 2 – fan electric motor; 3 – fan, impeller housing; 4 – heater tap; 15 – radiator.

The stove is controlled:

  • Changing the position of the lower cover of the fan casing using a lever (down-up);
  • Changing the position of the control unit levers (heating flaps of the side windows and windshield, air supply covers).

What breakdowns most often occur in the heating system?

  • Leaking radiator tap, pipes, radiator housing;
  • Malfunction of electrical equipment (fuse, mode switch, oxidation of wires, motor). The fan fuse is located in the mounting fuse block numbered F1 with a rating of 10A; below is a diagram of the mounting block.

Replacing the stove faucet

On a VAZ 2107 car, sometimes the faucet may leak or even become sour. They have to be used intensively and therefore often fail. Before you start replacing the faucet, purchase a set of gaskets for it. The tap is changed when the engine has cooled down.

Replacement sequence:

  1. Loosen the clamp of the inlet pipe (lower) and remove it from the tap;
  2. Use the lower lever in the control unit to close the dampers;
  3. Remove the glove compartment;
  4. We dismantle the air duct behind the glove compartment - to do this, disconnect it from the side deflector and remove it from the heater housing. Now, using a 7 key, loosen the crane rod and remove it.

Using a 10mm wrench, unscrew the valve from the radiator;

  • We disconnect the pipe and remove the heater valve; antifreeze may leak, it should be collected in a container;
  • Using a 10mm wrench, unscrew the pipe from the faucet;

We disconnect the tap and the pipe. That's all, the removal of the tap is completed.

What is a car heater heater

In fact, every car is equipped with an interior heating system, in which the heating device is considered one of the important elements. This part ensures that heat is removed from the coolant and further supplied to the cabin.

Where is the stove heater installed on the VAZ 2104–2107 and what functions does it perform?

The heater of the stove on all traditional Zhigulis is located in a specialized box under the front panel. The product is a heat exchanger, the important function of which is heat transfer from the coolant (antifreeze) with further distribution throughout the cabin. This unit works in the same way as the key heating device of the power unit. For the stove to function correctly, the heat exchanger needs to be constantly heated. This is achieved by connecting the heating device to the engine cooling system using tubes and rubber pipes and constant circulation of liquid using a water pump (pump).

The heater of the stove on the “classic” is located in a specialized box under the front panel

Stove heating device

The heat exchanger consists of two tanks and copper or metal honeycombs. The tanks are connected using soldering or sealant; it all depends on the material used to make the part. In addition to the heater, the key components of the stove are the fan and the control unit, which consists of levers and cables.

1 - additional motor speed resistor; 2 — fan casing; 3 — fan guide casing; 4 — spring brackets of the lower housing; 5 — heater body; 6 — air supply cover; 7 — gasket of the heating device; 8 - stove heater; 9 — sections of coolant pipe; 10 — heater valve; 11 — impeller of the electric heater motor; 12 — electric heater motor; 13 — spring latch of the heater motor; 14 — cushion of the heater motor; 15 — flap of the side air inlets; 16 — bottom cover (damper) of the heater, airflow for the feet

Air from the outside goes through the hole in the hood and enters the air intake casing made of plastic, located in the engine compartment under the windshield. Afterwards, the air flow enters the heat exchanger, which is heated by the coolant. When the car is normal or driving at low speed, the heater fan is turned on in the cabin, which drives cool air through the heater, thereby heating it and supplying it to the cabin.

The heating device of the stove consists of tanks and honeycombs through which coolant moves

When the car is moving at high speed, the fan does not need to be turned on, because the oncoming flow creates enough pressure to pump warm air. The more the coolant heats up, the more heat the heating device gives off. The level of liquid entering the heat exchanger is changed using a tap. Thanks to this, if there is a need to adjust the temperature in the cabin, for example, to make the air less hot, the tap is closed completely or partially using a plastic rod and lever.

Controlling the stove is very simple. There are several handles on the central panel:

  • the top one is needed to adjust the position of the stove tap (to the left - the tap is closed, to the right - open);
  • the middle handle changes the position of the air supply cover, thus changing the intensity of the warm air supply;
  • The lower lever provides adjustment of the damper of the heated glass air channels (position to the right - the air flow goes to the side windows, to the left - to the windshield).

The heater in the cabin is controlled using three levers that can be moved horizontally

Improvement of the heating system

For what reasons can the fan of the VAZ-2110 stove fail?
The design of the VAZ 2107 stove is far from perfect. Therefore, car owners modify it in a variety of ways. First of all, attempts are being made to improve the tightness of air ducts, especially at joints. This allows you to slightly increase the efficiency of heating the interior.

VAZ 2107 owners modify the heating system in a variety of ways

Fan replacement

Often, to improve the operation of the stove, car enthusiasts replace their original fan with a more powerful one, used in other VAZ models (for example, VAZ 2108). The factory fan motor is mounted on plastic bushings, which wear out quickly. As a result, shaft play appears, and a whistling noise becomes audible in the cabin when the fan is operating. Repair and lubrication of bushings in this case, as a rule, do not bring the expected effect. The VAZ 2108 fan electric motor is mounted on bearings. Therefore, installing it in the VAZ 2107 stove will not only increase the efficiency of heating the interior, but will also make the operation of the fan more reliable.

Usually, along with the fan electric motor, a number of other elements of the stove control unit are also changed. The rotation speed of the VAZ 2107 factory fan at a current of 4.5A is 3000 rpm. The VAZ 2108 electric motor consumes 14A at a frequency of 4100 rpm. Therefore, when replacing, you should install the appropriate fuse, resistor (usually from a Niva) and speed switch (for example, from a Kalina).

Video: modification of the VAZ 2107 stove

To dismantle the fan you will need:

  • flat and Phillips screwdrivers;
  • keys for 7 and 10;
  • round nose pliers.

The fan is removed in the following order.

  1. The instrument panel, shelf and glove box are dismantled.
  2. Use a 7 key to loosen the casing of the air damper control cable. The cable loop is removed from the lever.
  3. Use a 10mm wrench to unscrew the nut securing the heater housing.
  4. Use a flat screwdriver to remove the left and right air ducts from the heater body.
  5. Use a flat-head screwdriver to remove the latches that secure the fan to the stove.
  6. The wire terminals are disconnected.
  7. The fan is removed from the stove body.
  8. The impeller is removed. If necessary, use pliers.

The size of the new fan (from VAZ 2108) is slightly larger. Therefore, its installation will require some changes in the design of the stove. If only the motor is changed, it will be necessary to make an additional hole in the grille through which warm air enters the lower part of the cabin. If this is not done, the motor housing will rest against the grille.

Replacing the stove body

When installing a fan from a VAZ 2108, you will need to make a new frame, usually from plexiglass. This is quite labor-intensive and will require certain skills.

The material for a homemade frame when modifying the stove can be plexiglass

When making a new frame, all dimensions must be strictly observed. The slightest inaccuracies can lead to vibration or failure of the new fan. Having assembled the structure, you should lubricate the joints with sealant and install the new housing in place. After this, the noise level in the cabin usually decreases, and the stove begins to heat the air better.

When making a new frame for the motor, all dimensions must be strictly observed.

Other stove tuning options

Sometimes the design of the air ducts is modified. Additional holes are made in the stove body into which plumbing hoses are inserted. Through these hoses, connected to the side and bottom air ducts, when the engine is running, an additional flow of warm air is created onto the windows and into the legs.

Often the cause of poor interior heating is a clogged heater radiator. The coolant begins to circulate more slowly or completely stops circulating through the heating system, and the efficiency of air heating decreases noticeably. Usually in these cases the radiator is replaced with a new one.

A clogged heater radiator leads to a decrease in the efficiency of heating the interior.

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.

Principle of operation

Causes of heater malfunction in a car: how to diagnose and fix it

The heating system works simply - to ensure air heating, the driver uses the upper slider to open the antifreeze supply valve to the heater radiator. If the air supply damper is open (the middle slider is in the extreme right position), then the air flow through the box that separates the moisture and the damper enters the stove body. Passing through the radiator, the air heats up, and then moves depending on the location of the remaining dampers.

If the lower slider is moved to the right, then the heated air will go to the windshield area, and if it is positioned to the left, it will go to the center of the cabin and to the side windows. To supply heated air to the feet, the driver needs to lower the lower damper lever down.

When driving at high speeds, the air flow through the air intakes moves intensively, so it is not necessary to turn on the fan. But if the movement speed is not enough, the fan creates forced circulation.

Using dampers and a fan, the driver controls the stove - sets the speed of air movement, the degree of its heating and the area of ​​distribution.

What to do if the stove motor does not work (does not turn on, the blades do not spin)?

Possible causes of malfunctions and ways to eliminate them:

  • The wires are damaged, oxidized or their tips are loose.
  • Short to ground of the armature winding (the fuse immediately blows).
  • Wear, hanging of electric motor brushes, break in the armature winding, oxidation, wear of the commutator.
  • The heater switch is faulty.

Heater fan motor does not work at low speeds

  • An additional resistor has burned out, its wires are damaged or their tips are not tightly attached.
  • The heater switch is faulty.

Heater fan motor armature rotates slowly

  • The collector is dirty or oxidized.
  • Seizing of the armature shaft in the bearings (creaking, squealing, the fuse may blow).
  • Interturn short circuit of the armature winding (the fuse may blow).

Replacing the heater valve Lada 2105 (VAZ 2105)

Before the arrival of cold times, checking the heating system will not hurt, especially in Russia where sub-zero temperatures in some regions begin as early as September.

So this article about replacing the heater valve on a VAZ 2107 car will be of interest to many car owners who have such cars and do not yet have experience in such repairs. A typical reason for replacing the heater tap of a VAZ 2107 is that it begins to leak, leaving puddles of coolant on the interior carpets, which of course is not good.

Tools required for replacement: - key to “7” - key to “10” So how can you replace the heater on a VAZ 2107: - first you need to loosen the clamps on the heater hoses - now you need to remove the hoses from the pipes In order not to fill everything with coolant, make sure there is a container where it can be drained.

Of course, if your cooling system is not very depressurized and all the coolant is already in the cabin.

Factory (standard), ball or ceramic valve, which is better?

Among car owners on various forums, discussions constantly arise about which heater tap is better. Most often, battles unfold between two options: ball or ceramic. Almost no one doubts that a standard valve based on a rubber membrane is not reliable, more often than others it leaks, “sticks” and is especially susceptible to acidification. As proof of this, see the images above, where the reason for the replacement is a jammed faucet and a fluid leak.

Ball or ceramic?

We recommend purchasing a ceramic faucet. The body of such a faucet is ordinary, but the locking element consists of two ceramic plates with slots that rotate relative to each other.


Ceramic heater tap

A ball valve, in principle, is also not bad; the undoubted advantage of such a valve is its greater throughput compared to a ceramic one (when open, the passage hole is equal to the internal diameter of the pipe). At low temperatures this is especially noticeable, but the likelihood of souring is higher for a ball valve than for a ceramic one.

The stove blows cold air. How to turn on the stove VAZ 2107

» The heater blows cold air: how to turn on the heater on a VAZ 2107 How to turn on the heater so that hot air blows If you are cold in your car, then it’s time to turn on the heater. It seems like a simple question, but sometimes warm air comes out, something hums, but there is no heat and warming up does not help.

Therefore, this article is not just an answer to the question of how to turn on the heater on a VAZ 2107, and what to do if the heater blows cold air, but a consideration of all possible cases with specific recommendations.

Are you sure you turned on something, but the stove doesn’t heat up? First of all, if you are a beginner, check - are you sure you turned on the stove? The stove on the VAZ 2107 has: in fact, a toggle switch for the rotation speed of the stove fan, and three sliders - we’ll dwell on them in a little more detail. Upper: position all the way to the right - fully open the stove tap (maximum temperature); Middle: to the right all the way - air intake from the street, to the left - from the cabin.

As a rule, it heats up faster when taking air from the street. Lower: extreme left position – heated side windows, right – heated windshield.

The stove is a wide field for activity and creativity

One of the main complaints made by the owners of the domestic “Seven” is the insufficient power of the car’s heater, which is why even at full engine speed it can be quite cold in the cabin, and condensation or an ice crust forms on the windows. Modification of the VAZ-2107 stove is becoming one of the top priorities for a motorist who wants to increase the level of comfort of the car for the driver and passengers, as well as the quality of glass blowing while driving in the cold season.

Optimizing a VAZ stove turns out to be not so difficult if you have simple tools at hand, as well as access to spare parts from the heater of another car of the same brand, for example, a G8 or Nine, which has more power compared to this version of the car. You don’t even need special skills - it’s enough to know the design of the heater and have a standard set of tools and materials.

Control mechanism

The control of the VAZ 2107 stove is mechanical. It consists of a fan switch and a block of sliders. The control mechanism is installed on the center console at the top, which provides easy access to the elements.

There are three sliders of the control mechanism, and each of them controls its own element:

  1. The top one is responsible for supplying antifreeze to the radiator and is connected by a cable to a tap installed on the inlet pipe. The extreme left position of the slider means the tap is closed (the stove does not heat), the right position means the tap is open (antifreeze enters the radiator).
  2. Middle – air supply damper control. When you move it to the left, the damper shuts off the air supply from the street (closed air circulation in the cabin), while the right position means the air flow is open (air from the street enters the cabin).
  3. The lower one controls the damper for distributing the flow through the air ducts. Left position - the flow is supplied through the side and central deflectors, right - to the windshield area. Each of these sliders can be adjusted to any position to achieve optimal stove operation.

RADIATOR AND HEATER FAN

You should know that in order to always keep the interior of a five-wheeler warm and cozy, especially on winter days, you need to be able to increase the amount of heat supplied. Which part is directly responsible for supplying warm air? Of course, the radiator. But there is a problem - at the top five the fan is so loud that it makes you laugh.

It is very small and simply not capable of creating the required flow.

What to do? First, let's compare the fans on the VAZ 2105 and the VAZ 2108. The first motor consumes 4.5 A current and has a rotation speed of 3000 rpm, and the second one 14 A, but spins 4100 rpm. This already says something. It is recommended to replace the fan with another one.

Reasons for decreased performance

In addition to obvious malfunctions due to which the stove does not work or functions incorrectly, there are other problems with the heating system of the VAZ-2107 interior. The main one is a decrease in stove performance.

If the stove heats poorly, then the reason lies in:

  1. Malfunctions of the power plant cooling system (reduced pump performance, stuck thermostat).
  2. Radiator clogged.
  3. Formation of an air lock in the heater radiator.
  4. The air intake damper seal is worn out.

To find the cause of decreased performance, start by checking the heating of the heater radiator. To do this, heat the engine to operating temperature, fully open the antifreeze supply valve to the stove and hand check the degree of heating of the supply pipe before and after the valve and the radiator itself. If the pipeline is hot before the tap, but not after it, the tap is jammed. If the radiator does not warm up, the reason lies in severe clogging of the heat exchanger or a plug in it. If the pipeline does not warm up even to the tap, inspect the cooling system.

If the radiator warms up well, but it is noted that the stove heats worse, then check the functionality of the air intake damper and the condition of its seal. It wouldn’t hurt to check the stove body and air ducts for leaks and cracks.

To ensure that the VAZ-2107 heater heats well, before the winter period check the functionality of the tap, replace the antifreeze (with flushing the system), inspect the control mechanism and the functionality of the dampers.

Diagram and design of the heating system in the VAZ-2110

The heating unit itself is represented by several components:

  1. Electric motor. A ventilation device is fixed on it, designed to pump a hot air flow.
  2. A radiator device, the failure of which will lead to the inoperability of the stove. On old-style heating systems, the radiator assembly is not equipped with a valve designed to shut off the flow of coolant through the device. Therefore, the unit practically does not leak, since leaks are usually associated with the faucet. The absence of this element ensures the fastest heating of the car interior.
  3. Three dampers. One of them is designed to close and open the heating channel, the second is used for recirculation, and the third is necessary to control the heater.
  4. The resistor device is designed to regulate the blowing speed.

Principle of operation

The heating system works simply - to ensure air heating, the driver uses the upper slider to open the antifreeze supply valve to the heater radiator. If the air supply damper is open (the middle slider is in the extreme right position), then the air flow through the box that separates the moisture and the damper enters the stove body. Passing through the radiator, the air heats up, and then moves depending on the location of the remaining dampers.

If the lower slider is moved to the right, then the heated air will go to the windshield area, and if it is positioned to the left, it will go to the center of the cabin and to the side windows. To supply heated air to the feet, the driver needs to lower the lower damper lever down.

When driving at high speeds, the air flow through the air intakes moves intensively, so it is not necessary to turn on the fan. But if the movement speed is not enough, the fan creates forced circulation.

Using dampers and a fan, the driver controls the stove - sets the speed of air movement, the degree of its heating and the area of ​​distribution.

The stove stopped heating on the road

This is perhaps the most unfavorable option for any driver. It can be considered a gift of fate if this happened in the city, but often a complete failure of the standard heater occurs during long trips, and in most cases this is a very serious breakdown that can lead to overheating and jamming of the power unit.

Let's look at the main reasons why the VAZ-2101's stove suddenly stops working.

First of all, you should take care of checking the coolant level. If it fell heavily, or there is no oil in the expansion tank at all, that’s the reason. A quick and sharp drop in the antifreeze level will almost immediately affect the operation of the stove - it will stop blowing warm and, even more so, hot air, while the temperature sensor needle will begin to steadily rise to the red line.

To avoid making the situation worse, you should stop immediately and start looking for the cause of the leak.

All pipes of the cooling system, their connections to the CO units, and both radiators - the main one and the heater - are subject to inspection. If the problem is a hose that has lost its integrity (from time to time or due to mechanical stress), this is bad, but not fatal. Usually you don’t carry spare pipes with you. You are lucky if the hose is long enough to simply cut off the problem area, but the likelihood of such a situation is small. What can you recommend? Seal the hole with improvised means (electrical tape or tape). This will minimize leakage. All that remains is to add the missing amount of antifreeze and continue driving to the nearest service station to fix the problem.

There is no antifreeze lying around on the highway either, but water will do in a pinch - the engine is hot, so there is practically no risk of it freezing even in the most severe frost. But it may also happen that there will be problems with water. As a last resort, you can stuff snow into the expansion tank - yes, this is unhygienic, and it will take a long time to melt, but if the leak is fixed, this method is better than a complete stop due to a jammed engine.

Heater radiator VAZ-2101

It is much worse if one of the two radiators leaks. And if the leak is strong, there is only one way left - constantly add water with frequent stops until you get to the repair site. Of course, in any case, you have an alternative way - call a tow truck, but the further you are from home, the more expensive it will cost you. You can call a friend and try to get there in tow. But again, until you get to the garage, you will have to freeze, and when it’s minus 25 outside and the road is long, this method can hardly be called acceptable.

Procedure for replacing the heater tap

You should know that replacing the heater valve must be done with a cold engine. This will avoid all sorts of troubles associated with heated coolant. It is clear that any manipulation associated with the assembly and disassembly of automotive components must be carried out in a certain sequence. This equally applies to work such as replacing silent blocks and replacing the heater tap.

Removal of this tap is carried out in the following order:

  • after the car is prepared for repair work, it is necessary to gain access to the engine compartment,
  • in the engine compartment, use a screwdriver to loosen the clamp securing the supply hose, after which the hose is removed from the lower pipe of the heater valve,
  • The lower lever of the ventilation system control unit is set to the extreme right position. This closes the air dampers on the side air ducts,
  • remove the glove box body and storage shelf,
  • The nut securing the right air duct to the body is unscrewed. This is done using a 10mm socket wrench. After which the air duct is removed from the stud and disconnected from the side deflector of the dashboard,
  • you should loosen the bolt securing the heating tap drive rod using a 7mm socket wrench,
  • the rod shell is released from under the bracket, after which the rod tip is removed from the tap of the interior heater lever,
  • Unscrew the two bolts securing the tap to the stove radiator. To do this, you will need a 10mm spanner. At this stage, you will also need to secure the lower cage nut so that it does not fall out of the socket. For these purposes, you can use plasticine,
  • Now, in fact, you have reached the place where the heater tap is located. At this stage, it is removed - its pipe is removed from the seal, which is located in the partition of the engine compartment. There is also a rubber gasket here - it plays the role of a seal at the junction of the flanges of the heater valve and the stove radiator. During removal, some coolant may leak out of the heater core. To collect it you will need a rag,
  • Unscrew the two bolts securing the pipe to the heater tap. To do this, use a key of 10,
  • the pipe is removed. The place where the heater valve (its flange) and the pipe connect is also sealed with a rubber gasket.

At this point, the work on disassembling the unit is completed. You should begin installing the heater tap. This is done in the following sequence:

  • removed rubber gaskets must be replaced with new ones,
  • in the reverse order to that described above, the heater tap is installed,
  • the heater valve control lever moves to the extreme right position,
  • it is necessary to fill in the missing amount of coolant,
  • After the cooling system is filled with liquid, you need to check the tightness of the connections between the heater tap and the heater radiator, as well as the hose. If necessary, parts should be tightened,
  • Then all parts are assembled in reverse order.

It should be noted that these works, as well as adjusting the valves, can be performed by you yourself or with the help of car service specialists.

Replacing the heater valve on a VAZ: video instructions

https://youtube.com/watch?v=WU6ywPQrUw4

For a VAZ 2107, replacing the heater valve is one of the most important repairs. After all, this part is responsible for regulating the air temperature inside the car. The use of a crane also depends on the car model. For example, the VAZ 2108 is also equipped with a special damper for air supply, and on the VAZ 2110 and higher models there is no valve at all. On a VAZ 2107, the heater valve, the replacement of which will be presented step by step in this article, performs the function of supplying engine coolant to the radiator. This helps warm the air inside the car.

Removal and installation

If you decide to completely replace the stove, then this is done as follows:

  1. the ground wire is disconnected from the battery;
  2. the instrument panel and receiver panel are removed;
  3. the heater valve control lever is moved all the way to the right;
  4. the coolant is drained from the heating system;
  5. the clamps are loosened;
  6. the rubber hoses are disconnected from the heater pipes (they control the supply and removal of fluid);
  7. the seal is removed (it is recommended to watch a detailed video before removing);
  8. two bolts securing the bracket are turned out (they are located inside the engine compartments);
  9. the bolts of the fastening brackets are loosened;
  10. the rods are disconnected and the bracket is removed;
  11. the nozzles are removed on the left and right;
  12. nut fixing the right air duct for heating the side windows;

hoses for modification of the VAZ 2107 heater

heating The VAZ 2107 stove may be bad for other reasons. So, many car enthusiasts know that the left pipe, due to the design features of the stove, unfortunately fulfills its function, which is to blow the driver's glass. Because of this, the driver either has to open the window completely, which is irrational in winter, or constantly wipe the glass with a cloth, or modify the heater.

So, you will first need to remove the deflector from the pipe, for which you need to pry it from one side using a screwdriver and slightly pull it forward, after which you need to repeat the same steps on the other side. If you do everything correctly, you should have the deflector in your hands. It is held in place by small tendrils in the body of the torpedo, and you can stick your hand into it and calmly pull the torpedo body out of the deflector. Take a 50mm computer fan and try it on exactly in the center of the deflector housing, leaving marks on the fan dimensions. Using a hacksaw or a utility knife, you will need to make cuts in the plastic, then you need to connect them and break off pieces of plastic. You need to install a fan in the resulting opening, try it, and it must fit tightly, otherwise it will constantly blow.

dangling, you can return the inner part of the deflector, which has blades, to its place, however, most likely, the fan will not allow the blades of the internal part to turn the maximum angle

It is necessary to mark the part that is in the way, and cut it off; you should also cut off everything unnecessary from the blades with the holder - here you must act as carefully as possible, since the blades are very fragile. Assemble the structure and check if the blades move normally

Using cut pieces of plastic, seal all unnecessary rear openings with them - place the plastic on the sealant.

In the car interior, you must first insert a fan into the nozzle area, and then install it and the deflector housing, and you need to direct the fan into the cut hole. You can’t install and forget about the blades. It is best to connect the cooler to the wire to the stove; it also makes sense to put a special button for the cooler, but if this is not possible, then just attach one to its wire with the stove fan.

The best heating radiators for VAZ 2114

Structurally, heating radiators differ not only in the material used for their manufacture, but also in the presence or absence of turbulence. They are made from copper or aluminum.

Copper radiators

Purchasing a radiator made of copper is an excellent choice. It has remarkable heat transfer properties; if the need arises, it can be repaired. The disadvantages are high cost and significant weight.

Aluminum radiators

Such radiators are much cheaper, but if they break, they cannot be replaced. Such devices heat up quickly, but also cool down so quickly. They are produced in a wide range and are relatively inexpensive.

The size of the honeycomb is of great importance. The smaller they are, the better the rapid heating of the air. But in terms of efficiency, they cannot compete with radiators with large cells, although, undoubtedly, the low price and light weight are positive aspects.

At the time of purchase, you should ask the seller about the presence of plastic swirlers or turbulators in the design. In their presence, better transfer from the liquid to the material of the swirler honeycomb is observed. If they are present, the efficiency of the radiator increases by 25-30%. From here it becomes clear that it is better to purchase a radiator with a swirler. The choice of material is at the discretion of the buyer.
