How to increase the speed of the engine stove VAZ 2107. We modernize and change the stove on the "seven" with your own hands. Control stove is carried out

Why not warming the stove VAZ-2107

And again the weather threatens cold. For those who with the heater is not all right, the most important became the question of how to get the "stove" to warm? First of all, we define the cause of the fault. The culprit may be the under-heated engine, "delivered" system of cooling or malfunction of the heater itself. If the stove fan does not spin, electrical conductors are faulting .

Often, the cause of cold in the salon-unfavorable engine

Signs - Temperature on the pointer in the white zone, the engine is long warmed. Normal warming at a temperature -20 looks like this: we start the engine, for 8-10 minutes on idling The engine must warm up to 40-50 degrees (the very beginning of the white sector of the temperature pointer scale). If the temperature rose above is good, less bad. The thermostat is faulty. Further, we go to 1-2 transmission, and for 5-8 minutes, the temperature rises to 80 (the border of the white and green zone). Not warmed up to 80- replacement! Temporarily can do the insulation of the radiator with cardboard or something else. But do not forget that if the engine is given a load (stuck and dropped), it can boil. Therefore, the cardboard should be easily and quickly pulled out.

Air in the cooling system

First of all, check the level of toosol in expansion tank, serviceability of the radiator cork. If Tosol is diluted with water, it is bad, it will freeze, it is necessary to replace. With a faulty radiator cork, air will remain in the system, and this will lead to poor circulation and cold in the cabin. We buy and put a new plug, tosol and lack disappears.

Aerial cork can remain and after repairing the cooling system. Remove air cained the car, with preheated to 80 grams. The engine, on the hill to lift the front. Then, removing the radiator cork, drive the motor for 2000 - 3000 revs within a few minutes. After the release of the air, it remains only to add toosol and close the radiator cork.

Next, check the position of the stove control levers

Blue - manages air supply. Red-crane Tosol feed. They must be open (to the right to the stop). Sometimes a faucet takes. Find it under the glove compartment and check it, it should be opened to the end, you can help your hand, simultaneously with the lever. Only, work carefully, details are thin fragile, you can break. It is convenient to move the lever with your left hand, and the right to turn the crane.

The driver's faucet is closed

The operation of the air damper is tested with the fan turned on. The lever to the right of the stove blows strongly, the least is weaker. If there is no difference, the cable is bad, the stove will have to shoot.

The stove blows bad on the left side

Heater device (stove) VAZ-2107

The third lever controls the distribution of warm air between the windshield and side windows. The cable that leads to it (21), controls three flaps- (20) two of them open and closed the air supply to side windows. The third flap in the figure is not visible, it is here (22) and can overlap the air outlet to the windshield. Luggage position: right on the windshield, leaving the side windows. Why does not blow on the left side?
1. The fan in the stove is arranged so that wrapping warm air in right sideand the left side goes less. This is a constructive feature and something is difficult to change.
2. The stove disassembled and damaged the air duct (4) or the left damper.
3. You fully open the bottom damper with the handle (1), or it has a broken lock. For normal blowing glasses, this damper must be covered. If the lock is broken, you can adjust the gum, hooking it by the "Support" handle, or somewhere else.

Some craftsmen put an additional fan from the computer processor in the deflector (4) of the nozzle. You can buy and put a fan in the instrument panel with a connection to the cigarette lighter, send it to the side glass and put the speed smaller.

Another reason is the bad tosol circulation through the stove

We check the circulation as follows: the engine is heated to 80, at idle to bring the hand to the outlet from the stove (at the right foot of the driver) we give gas and keep speed 2500. If you feel that the air has become noticeably warmer, you have a bad circulation through the stove. The reasons:
-bid stove radiator if the car is old and you poured into the "sealant" radiator, mustard and other nastiness;
- is a non-standard stove crane (ball, ceramic), which has channels of reduced diameter, or not fully opens. There are defective cranes. It can overlap the circulation so that Tosol flows thin flowing. After replacing the native crane will come back.
We check the circulation more accurately: at idle, on barely warm engine (20-30 degrees), remove the upper rubber pipe at the outlet of the stove (under the hood) and substitute any dishes. The jet should be thick enough and smooth. Thin trickle, barely run- remove and check first the crane, and then (if the crane is in order) and the radiator. Radiator scored You can try to rinse with hot water (in the hole where the tube), sometimes it helps.

It happens that collecting the stove, the radiator talked badly

cold air falls past him and in the cabin is cold. You have to disassemble the stove and gently seal everything.
If you decide to disassemble the stove yourself, look at the video.

From myself I will add a tip: Remove the gearbox lever and do not have to disconnect the wires of the console (beard).
All the best to you and the heat of your salon!

The ventilation and heating system serves to create comfortable climatic conditions for the driver and passengers inside the car's interior. With its help, we, being inside the car, can breathe fresh air, as well as maintain the required temperature.

In this article, we will look at how the heating and VAZ-2107 ventilation system works. We will deal with the peculiarities of its design, the main faults and methods of their elimination.

What is the ventilation and heating system

The VAZ-2107 heating system is integrated into the engine cooling system. The heating of the air entering into the interior occurs in the process of the refrigerant heat exchange carried out using an additional radiator. It consists of the following elements:

heater;
control module;
air lines;
adjustable nozzles.

What is heater

The main element of the system is the heater, or as it is also called, "stove". It includes:

plastic case with air flow lid;
radiator heater with crane;
electric fan.

In fact, the heater is the most real "stove". The upper part of its housing is equipped with an adjustable aircraft lid. Through it, the outer air enters the "stove". Inside the case there is a radiator of the heater through which the heated refrigerant (Tosol or antifreeze) is moving.
Due to it, the air is heated. The radiator is equipped with a crane that allows you to adjust the intensity of the coolant movement through it, or to overlap it. In VAZ-2107 cars, the salon heating system in the warm season is usually disconnected. And it is done using this device.

The heated air itself cannot flow into the salon with the necessary pressure, even during a quick ride. For its discharge, a fan with an electrical drive (engine) is served. It is also placed inside the heater housing. The "seven" fan can work in three different power modes.

Control module

The VAZ-2107 heating system is controlled by a special module placed at the bottom dashboard. Its design includes three levers and a heater fan mode switch.

The topmost lever ensures the control of the "stove" crane. In the extreme left position it is closed, and the cooling fluid moves into the heating radiator. If the switch to move to the right, the refrigerant will start to enter it in full, heating the air to the maximum.

The middle lever allows you to close-open the aircraft lid. In the left position, it will be completely closed, and the outer air will not be able to enter the salon. The lid opens completely when we move the switch to the leftmost position.

The VAZ-2107 heating system provides for the distribution of air flows for blowing wind and front side glasses. It is carried out using the bottom lever. In the right position, the air is directed to the side windows, in the left - on the wind.

The heater crane, aircraft lid, as well as dampers, arresting air flows, are driven by cables.

Fan mode switch is on the left of the control levers. It has four positions under which the fan:

switched off;
works at the first speed;
at the second speed;
at the third speed.

Air pipelines

Air bodies serve to transport warm (cold) air to wind and side windows. There are only three of them:

left;
right;
central.

Each of the air lines is a plastic "sleeve" of a certain form. In one end, they are attached to the heater housing, the second to the corresponding nozzle. In order to reduce air losses during transmission, the compounds are sealed with rubber cuffs.

Nozzles

Nozzle, or a deflector is a device through which the air falls directly into the salon. The VAZ-2107 heating system includes four deflectors: left, two central and right. A feature of the nozzle design is a mechanism that allows changing the position of the lamellas inside it, redirecting the air flow from side to side, and also overlap it.

How it works

After examining the device of the VAZ-2107 heating system, it is easy to understand how it functions. So, the air through the grilles on the hood of the car and the aircraft lid falls into the heater housing. There, depending on the temperature of the coolant and the position of the damper of the "stove" crane, it warms up to a certain temperature, and moves further through the aircraft operating through the deflectors in the cabin. The intensity of the air flow depends on the speed of the machine (when the fan is turned off), or on the position of the fan modes switch. By changing the position of the lower lever of the control module, as well as the position of the lamellas in the nozzles, we direct the warm air to where we need to be on the windshield, on the side windows, or in the center of the cabin.

Injector and carburetor: Is there a difference in the design of the heating system

The VAZ-2107 heating system (injector) is no different from the one that old carburetor "seven" was equipped. Their designs and the principle of work are absolutely identical. Radiators, their cranes, electric fans and all other elements of interchangeable. The only thing than the heating system of the VAZ-2107 (carburetor) may differ, it is the material of the manufacturer of the "stove" radiator. Older "seven" they had copper.

Common problems and ways to eliminate them

Despite the simplicity of the design, the VAZ-2107 heating system fails quite often. The most vulnerable places are:

power faucet;
fan (electric motor);
radiator "stove".

Crane the heater "Sevenki", like all classic vases, breaks most often. The most popular malfunction is to flow caused by the depressurization of the case. A similar problem is solved by replacing spare parts. Crane repair in most cases is impossible.

Another common breakdown is to break the drive cable. To replace it, you will have to dismantle the faucet, because it is impossible to get to its fastening from the locking device without removing. Also follow the tension of the cable. If you allow its sagging, the valve of the crane will not open completely.

As for the fan, it is impossible to call it reliable. It usually fails with the onset of cold weather. The cause of the malfunction of the electric motor at best, wear bearings or brushes become, in worst - open or closure of windings. Repair the situation can repair the electric motor or its replacement.

The heater radiator also has two "diseases": flow and clogging. The first malfunction can be caused by either mechanical damage or chemical processes. Today, radiators are made of aluminum alloy, which is not particularly resistant to technical fluids. And if old copper radiators could still be sought, then modern can only be replaced.

The heat exchanger clogging also occurs as a result of chemical processes. Scale gradually settles on the walls of the device tubes and with time limits the normal circulation of the coolant. This leads to the fact that the air injected into the salon does not heat up to the desired temperature. You can get rid of a similar problem by washing the radiator special fluidsIn extreme cases - replacement of the device.

Stove VAZ 2107. Development and repair of the salon heating system

The heating system using the heat of the coolant is responsible for heating the salon VAZ 2107. This scheme recognized as optimal for cars with DVS has found applications in cars from the middle of the 20th century.

Like any car knot, the stove of VAZ 2107 can stop working. In winter, such a breakdown makes the operation of the car impossible: the glasses sweat or be covered by frost, which deteriorates the review. For efficient repair, it is necessary to know well the device of the heating system of the cabin.

Device and operation of the heating system VAZ 2107

The system includes the following components:

Wasing heater 2107, whose task is to heat the air. The main element of the heater is a radiator through which the coolant circulates.
Fan, guiding heated air into the cabin. It is attached to the casing through elastic pillows that quench vibration.
The heater control system, which includes a fan button, handle and levion of heating control system.

The heating system works like this:

Through the grids on the hood, the air falls into the aircraftrip box, located in the engine compartment near windshield.

In case of rain or shower, water is separated from the air and flows into the holes in the box. This allows you to use the stove into any weather, but as long as the radiator is not heated, the air will be raw during the rain in the interior.

The air flow is directed to the heater of the VAZ 2107 and heats up, passing through the radiator. Heating is adjustable with a crane that adjusts the amount of undergoing coolant. The crane control is made by means of flexible thrust attached to the control lever.

During movement, the air flow falls into the operating space and the air itself enters the heater. During the stop or at a low speed, an electric fan is used, controlled by a switch having three positions: "off", "full speed" and "small speed". The reduced speed is provided by turning on the electric motor through the resistor, which reduces the voltage on the engine winding.

After the radiator, the air falls into the air bodies and comes out through deflectors, allowing the flow direction. Warm air can be directed to the windshield and side windows, under the feet to the driver and the front passenger.

Control elements of the air flow from the stove of VAZ 2107:

Air distribution fan cover, adjusting air flow.
Levers and handles, changing the position of air flow covers and dampers, regulating blowing.

Before repairing the stove of VAZ 2107, it is necessary to deal with the causes of malfunction.

Faults of the stove of VAZ 2107 and how to eliminate them

If the stove of the VAZ 2107 does not heat and with the heater turned on, the air coming out of the deflectors remains cold, the reasons may be such:

Restaging the cooling system. This can occur when replacing antifreeze or repair of cooling system nodes. To restore heating, you need to remove the air plug.
The tap of the heater in the open position continues to overlap the highway. The reason for this in clogging the crane or education in it is due to use in the water system instead of antifreeze. To restore the health of the heater, the crane must be dismantled, and then clean or replace the new one.
The stove remains cold when the crane is open. The cause of such a phenomenon may be non-working pump. This breakdown quickly makes itself felt by the quick overheating of the engine, not to notice it is impossible. If the engine is heated to operating temperature, And the nozzles going to the heater VAZ 2107 remain cold, the repair of the pump is necessary. One of the reasons why pump will not work, is a slip or broken of the generator belt.
The air is cold, and the slotting hose is hot. it frequent problemwhich is the consequence of the slaum of the radiator. They can be clogged due to scale, oil entering antifreeze or use "additives to eliminate leaks." In this case, the stove of the VAZ 2107 must be dismantled and rinsed.
Radiator nozzles are hot, and the air is cold. This happens when the partition is shifted in the radiator and the direct path between the inlet and drain pipes is formed. It is possible to restore the performance by replacing the radiator.

Another type of breakage is the leakage of antifreeze. This manifests itself in the appearance of condensate on glasses or leakage of antifreeze into the cabin under the feet of the passenger and the driver. The reasons here are:

Antifreeze breaks through the heater crane. In this case, it can be replaced, without removing the radiator.
The leakage occurs through the bursting nozzle. Solution - replacement of the nozzle to the new one.
Drive radiator heater. In this case, the repair of the stove of the VAZ 2107 is soldered or replacing the radiator.

When leakage of antifreeze in the heater breakdown, the repair must be made immediately - ethylene glycol, contained in antifreeze, toxic and inhalation of its vapor causes serious harm to the body.

Dismantling of the heating radiator VAZ 2107

To perform work, you need a cross screwdriver and a set of keys (horn and end).

Sequence of operations:

weaken the hose clamps of the heater hoses located in the engine compartment;
remove the hoses from the heater radiator nozzles (there is a small leakage of antifreeze);
unscrew the screws fixing the rubber seal;
dismantle the seal;
unscrew the tape recorder panel;
disconnect the cable from the crane of the VAZ 2107 stove;
using a screwdriver, dismantle the brackets on the fan casing;
lower the casing;
remove the heater radiator.

Repair of the radiator of heating VAZ 2107

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

A clogged radiator can be ringed with water pressure. Skip on the walls of the cells can be deleted using special tooldissolving it.

Copper (brass) radiator can be sought. With the help of a powerful soldering iron and solder, you can close the hole or crack. Drinking aluminum radiators are subject to replacement.

Important: To eliminate leaks in a stove radiator or engine cooling system, you should not use the means added to antifreeze - they may cause clogging of the VAZ 2107 radiator.

Assembling the heater VAZ 2107

Repair of the VAZ 2107 stove completes the heater assembly. Collect it in the sequence, reverse disassembly. Work has a number of features:

rubber gaskets must be replaced with new and lubricate them with silicone sealant;
before assembling the heater to the radiator, it is necessary to attach nozzles and crane;
you can not drag nuts, so as not to crush the gaskets;
before putting on rubber hoses, the outer surface of the metal nozzles of the radiator must be treated with sealant;
after the heater of the VAZ 2107 is assembled and connected, you must not forget to add antifreeze into the system and check its tightness.

IMPORTANT: VAZ 2107 stove repair must be made in a complex with a service level of configuration of the engine cooling system. This approach allows you to accurately determine the cause of the breakage and reliably eliminate it.

Tuning stove VAZ 2107

Improve the heater VAZ 2107 can be installed by installing an additional fan to enhance the air flow to the windows. Another common type of tuning of the stove VAZ 2107 is replacing the fan modes switch to the button.

VAZ 2107 stove: device and repair

Every year, a good motorist should think about the preparation of his car to winter. Most are limited to the change of rubber and motor oil. But checks require all systems that will operate at low air temperature. These include the stove of the VAZ 2107, which each motorist should use.

On cars up to 40-50 years old, the 20th century there was no stove, although the hot engine itself served as a prototype of the stove. A diagram at which the motor and its coolant serves as a source of heat, was recognized as the most optimal, was not implemented immediately. Despite the motor, which was a source of heat, the heating scheme sometimes included a wheel with coal under the feet of the passenger.

The car heating system can suddenly fail for many reasons, and if in the summer it is possible to close the eyes, it is winter at low temperatures and wrapped off all the windows, and the operation of the car will become dangerous, and may be impossible. It is necessary to know well and imagine the VAZ 2107 stove device so that in the cold season there were no unpleasant surprises with salon heating.

The heating circuit includes the following parts:

Heater, main part of which is radiator 5; His task is to heat the air penetrating outside;
The heater fan, or the motor (motor) 14, which sends heated air into the cabin, it rests in a special casing 16 on elastic pillows for vibration.
The heater control system is a fan button, (you can use two modes of operation) 18, three heating modes control knobs;

1, 9 - pipes of air ducts heating side braids on the right and left;

2 - air duct of windshield heating;

3 - radiator casing;

4 - aircraft lid; 5 - heater radiator;

6 - Crane (crane) of the heater;

7, 8 radiator hoses for removal and supply of hot liquid cooling system.

10 - swivel deflectors;

11 - duct damper;

12 - air distribution cover;

17 - control traction;

19 - Central Air Force

The principle of operation of the heating system is as follows:

Air for heating comes outside, through the "grid" of the hood.
In the back of the engine compartment there is a special seal made of rubber box for air flow.
In it, the air flow is sent to the heater, separated from rainwater in the case of a shower on the street. You can use the heater during the rain, but the air in the cabin will be wet until the radiator is heated.
Next, the air is heated by the heater, more precisely, its radiator that feeds on the liquid of the car cooling system. The degree of heating is regulated by the amount of hot fluid that adjusts the heater's tap. The heater crane is controlled by a flexible burden coming from the control lever.
The air may passively enter the salon at high speed of the car, as it is supplanted with the cold air entering the increasing space, creating an increased pressure zone, and may be carried away by turning on the heater fan. Therefore, at high speed, you can use the heating system without additional load on the power supply. This switching is carried out by clicking the fan switch having three positions - neutral and two inclusion speeds: small and increased. When tuning the cabin instead of a switch, a button can be installed. These velocities provide a resistor that increases the chain resistance and reduced impeller movement. To use forced circulation of air should be at low speeds of movement, as well as when standing in traffic jams.
Fan "drives" airflow on the system of air ducts to the parties, in side stool For the review of the rear-view mirrors, and warm air leaves the deflector lattices, which can be changed the direction for the best blowing. Also warm air leaves the air duct for blowing wind (windshield) glass.

In the figure, blue shows the circuit circulation of cold air flows, orange - the flow diagram of the heated. We list the main parts of the heating system in "Profile"

1-air distribution cover;

2 - Fan Electric Motor (Motor);

3 - Karlson, impeller housing;

4 - Heater Crane.

15 - copper shirt (radiator body);

The heater is managed:

Changing the position of the air distribution cover of the fan casing using the lever (up-down);
By changing the position of the arms of the control unit (air flow covers, windshield heating valve and side brake).

What malfunctions are most often found in the heating system

Leakage of compounds (nozzles, heater crane, radiator body), which is manifested by a county;
Malfunction of electrical equipment of the heating system (mode switch, fuse, wire oxidation, motor). The fan of the fan is in the block under the number F The fan does not consume too much energy, so the fuse is designed for the transmitted current 10 A. The following is placed below mounting block, the desired fuse of red.

The most important thing is that on this fuse are located except the impeller, the reverse and heating lamps are located rear glass. Therefore, it is not recommended for a long time to include all the consumers of energy and give reverse, for example, to get out of a snowdrift. The scheme does not provide for the presence of a relay for these chains.

One of the most common operations is to replace the heater crane.

On the VAZ 2107 can sometimes leak the puddle on the front rug on the right, to the feet of the passenger. So, the driver's faucet is faulty. They have to use quite often.

Before changing the crane, you need to purchase a set of pads for it. Replacing the crane is made under the cold engine, and then you can burn. Motor must be jamming for a half hour for comfortable work.

Sequencing:

When the engine is cooled, first weave the clamping nozzle clamp, and remove from the crane (lower nozzle);
The lower lever in the control unit is translated into the extreme right position, then the flaps will be closed.
We remove the "Bardac"
Remove the air duct (right) and disconnect it with a side deflector, then remove it from the heater radiator casing. Now you can easily weaken the traction on 7 mm and remove its tip from the crane.
We take a 10 mm cape key and release a crane from the radiator;
Remove the heater crane by disconnecting the nozzle. From the spot of separation can be run by Tosol, which cools the motor. It needs to be collected.
We take the key to 10, turns away the bolts that are fixed to the tip.
Disconnect the faucet and nozzle. At this removal of the crane is over.

To install a new crane you need to use new gaskets. After replacing the installation, we perform in exactly the same sequence, only on the contrary.

We need to use a new crane carefully, also need to be addressed to the coolant engine (more precisely in the expansion tank).

Salon heating systems VAZ 2107 (VAZ 2107 stove).

Problems with the machine most often begin with the arrival of cold weather, it applies to the domestic auto industry, the main problem of which is often the unsatisfactory work of the windshield heating system and the car's salon.

And the cold is coming again. For those who at the VAZ 2107, the salon heater warms badly, the question arises - how to make the "stove" warm better? In most car owners, the seven causes discontent the work of the stove, or the heater of the cabin. Indeed, the classics of this brand the ovens are very low.

But this problem can be solved by the refinement of the stove with their own hands. To improve the work of the heater, special tools or skills will not be required, everything is performed using remedies.

Why the stove on the VAZ 2107 heats badly, reasons:

Frequent cause is an underwritten engine.

Signs - a temperature pointer is in the white zone, the engine is long warmed. At temperatures on Street -20, for 8-10 minutes of operation of the engine at idle, it should warm up to 40-50 degrees (the very beginning of the white zone of the temperature pointer). If the temperature rose less - bad (thermostat is defective), above well. Next, you need to drive 1-2 transmission, and in 5-8 minutes, the temperature should rise to 80 degrees (the border of the green and white zone). If the engine did not warm up to 80 - the thermostat for replacement!

Air in the cooling system.

First of all, in the expansion tank it is necessary to check the level of antifreeze and the serviceability of the radiator cork. If a cork plugging the radiator is faulty in the system will remain air, because of this there will be poor cooling fluid circulation and the cold air in the cabin, respectively.

The stove blows badly on the left side

The lower damper is fully opened, or it has a broken lock. For a full blowing glass, this damper must be covered. If it is not fixed, you can use an elastic band, hooking it for the handle of the "sucking", or somewhere else.

Refine the stove of the VAZ 2107 to rare better.

As practice shows, it gives a sufficient amount of heat and its improvement is not required. So in order to increase the efficiency of the heater, you need to finalize the blower system. Mix with sealant all air ducts, especially in places of their compounds. This is especially true for VAZ 2105 - 2107 cars, due to their features of the duct design.

Replacing the stove motor.

Improve the stove, can be installed instead of an engine with an impeller, a snail installation used in VAZ models 2108-2109. Such tuning increase air flow and reduce noise. The motor used in these models differs from a seven-increasing speed of revolutions and greater power. For its installation, a small refinement of the stove case is required - due to the larger size, it is necessary to remove the comb, which directs the flow of air to the legs.

The impeller can be left native, but it is necessary to increase the hole in it with a diameter of up to 7 mm, under the motor of the eight of the eight.

Such refinement of the stove also requires the replacement of the switch and the resistor. Both details are taken from the same model as the motor. The VAZ 2107 switch is designed for a smaller current, and when operating with a powerful engine can simply melt. Native resistance of the VAZ 2107 will not allow the motor to work on full powerFor this, the resistor changes.

We start with full disassembly of the heater body. From the bottom of the stove is cut almost everything, except for fasteners and frames. Next, we make the housing for snail. For this purpose, you can use any durable material - polycarbonate, plastic, plexiglass, etc. Four walls of the future case are cut out of the material (which you have chosen) and are screwed to the bottom of the stove.

After all the actions done, the lower part wear on the middle, pre-remove the diffuser. The dimensions need to be adjusted so that the snail is accurately entered into the housing and did not perform for the mounting of the radiator located on the middle part.

At this stage of work should be given special attentionIf the housing is large, then you will not be able to install the stove in the regular place. After an accurate fit of the sizes of the new case, all the joints need to be marked with a sealant.

Take the air ducts. You can take advantage of available plumbing hoses and cuffs. In the new housing of the stove in the bottom, on both sides, holes are cut out, suitable diameter for cuffs. The hoses are installed in them - the side connects with the right and left ducts, the lower side of the legs, for the exemption of the warm air flow.

For heating rear passengers You can additionally install a couple of hoses of greater length. The amount of heat given to the stove radiator, and the snail power is quite enough. The locations of the side air ducts and the combination of hoses are labeled by a sealant, to eliminate the loss of warm air.

Such a refinement will increase the efficiency of the stove on the VAZ 2107 2-3 times as the quality of blowing glass, the large stream of warm air does not allow to move the windows and heating the cabin. Such upgrades of the salon heater is available to everyone and does not require high costs.

Note: You should remember when installing a snail and engine, a switch is required. Make sure the stove fuse has a rated current required for the work of the modified stove.

Altep Stoves (snail) VAZ-2108 on VAZ-2107: Video

Effective automotive work heating system Important at any time of the year, but especially in winter. The appearance of faults will negatively affect the comfort of the car control as a whole. Refinement of the stove on the VAZ 2107 is relevant for this model of the car, since the work of the heater in them is weak place.

The top is designed to supply the refrigerant to the radiator node. This slider is connected to the crawl by the cable. It is mounted on the input highway. With the leftmost position, the device does not work and the heating knot does not warm. If it is translated into the right state, it will open and refrigerant will fall into the radiator device.
In the middle position it is possible to control the dampers of the inflow of air flow. If the slider moves to the left state, overlapping the air supply from the street. It will circulate only in the car. When moving to the extreme right position, the air comes from the street inside the car.
In the lower state, the damper is controlled, which is designed to distribute air flow through blowers. In the extreme left position, the stream enters side deflectors And to the center, and in the right - on the windshield.

Each of the listed levers can be installed in any state, this will make it possible to achieve the optimal functioning of the heating node.

Disadvantages of the heater in VAZ-2107

The need to improve or improve the work system may arise as a result of such shortcomings:

Ineffective blowing the back of the cabin. because of constructive features, warm air with difficulty goes to passengers sitting at the back. It will take time to effectively warm the entire car interior.
From the left deflex device on the "seven" there is a weak air flow.
The electric motor of the heating node works too loudly.
The radiator crane is also considered a weak place. With long-term operation, it gives leaks, which leads to a decrease in the volume of antifreeze in the system.

How to modify and upgrade the stove with your own hands?

Improve the operation of the heating system on the "seven" in the following ways:

redo the side ventilation of windows;
make the flap upgrade;
make a refinement of the snow blowing system to increase its efficiency;
improve the operation of the heating system of the back of the cabin;
refine the thermostat;
improve the functioning of the wagoning highway;
making an additional water pump.

On the versions of the modernization of the heating system in VAZ 2107 cars, User Yegor Panther told.

Improving side ventilation

We need to refine the system of lateral ventilation after purchasing an additional fan. The device is mounted in the left highway, which will allow forcibly submitted airflow to the deflector.

The tuning procedure looks like this:

At the first stage, a dismantling of a deflex device from a highway is made. To perform this task, you need to use a screwdriver. The deflector in the cabin is coming and removed, it must be pulled forward. Similar actions are performed on the other side of the stove.
Devaling the device is accurately done so as not to leave traces of damage on the central console.
If the deflector is extracted, you need to remove the tracking device from the torpedo. This element is mounted in the central console using special mustache. The essence of this modernization is that for forced air flow supply to the heating system, a classic computer fan is mounted.
To mount the ventilating device, the element must first be treated with the deflector housing. After applying to the plastic, the marker or pencil should be labeled. Using the stationery knife, a plastic cut is performed on a deflector.
If the dimensions are noted exactly, the ventilating device will be tightly installed in the housing. This is important because this installation will allow you to prevent the database when driving.
After completing the installation of the fan, it is necessary to make sure that its blades are normally rotated and nothing bothers them. If there are problems, the device is fitted. If necessary, the blades can be short.
To ensure the supply of effective air flow and the absence of reverse thrust, the entire design should be hermetic. Therefore, using sealant or plastic residues, which appeared after the deflector cut, the cracks are cleaned.
If all actions are performed, the ventilator is installed in the highway, after which it is mounted on the body of the deflector element.
After performing all installation steps it is necessary to work with an electrical component. It is recommended to connect the fan electrically to the conductor, where the current appears when the ignition is activated. This option is more convenient. Connecting the device to the control cable of the heating node.

Modernization of the valve

Refinement of the VAZ 2107 stove, consisting in the upgrade of the lower damper system, is the easiest in the implementation by the option. If all actions are completed correctly, the device will not be arbitrarily open or closed when the machine rides on the bodies. This will ensure efficient and the same blowing both glasses.

The modernization procedure is carried out like this:

It is necessary to visually assess the heating housing. In its corner, the opening of the required diameter is settled to perform work. If it is not, it is drilled. For this, a drill with a diameter of 6 mm is used.
In the hole made from the inside, a bolt is installed. The flap itself closes.
After that, with the help of the same drill, drill holes directly in the device handle. It is necessary to drill so that the hole is located at the bolt level set earlier. At the same time, the length of the screw should be such a damper, the element could freely go into the hole made.
If everything is done correctly, the bolt is tightened with a nut. It is recommended to use a black detail, then it will be difficult to see.

The user of the Nail Poroshin told about the features of the reflection of the air damper.

Modernization of the heating system of the rear seats

To upgrade the warming system rear seats The installation of an additional "snail", which can be used from VAZ 2108:

First you need to make the case for fixing the "snail". To perform this task, you need to cut the plexiglass.
Using the usual hairdryer, it is necessary to carefully make bends on the glass so that it turned out as shown in the photo.
Then, with a hair dryer, it is necessary to carefully change the shape of the case. It is necessary to act neatly, otherwise "snail" may not be in the landing site.
When you run the task, you can remove the device plug using the stationery knife. This will reduce the dimensions of the part by approximately 3 cm.
Then the manufacture of lateral wall structures is performed. To do this, you can use duralle or other similar material. The wall thickness should be 1.5 mm.
The next step will be the removal of all gaps. For this purpose, the joints of the device must be sealed with the help of glue-sealant or other means.
Then you need to work with the channels by which the air will go to the holes of the blowers. These elements are recommended to make collapsible. For the manufacture, it is desirable to use similar material.
In order to reduce the size of the resistance and removal of the twist of the corners of the air channels must be smooth. They can be made of duralle.
At the next stage, it is necessary to build slots to be used for leg heating. We are talking about the front blowing - for the driver and passenger. The slots should be equipped with dampers. You can additionally install an alternating resistor device that will be used to control the motor revolutions. This element can be put instead of a resistor intended for changing the brightness of the backlight.
The main stage in this modernization is the construction of a system of efficient heating of the feet of passengers sitting from behind. To do this, you must additionally install several pipes of greater length. The radiator device is quite powerful and its power will be enough to supply the air flow back. All connecting places of highways and blowers are sealed to prevent the warm air flow leakage.

Improving the efficiency of blowing legs

To improve the efficiency of blowing the legs, it is necessary to replace the standard fan to another, you can use the device from the VAZ 2108.

The upgrade procedure is performed as follows:

The first stage is performed in the car. It is necessary to disassemble the bottom of the heating node. It has a regular ventilator.
Dismantling fan is performed. It will no longer need it, it can be disposed of.
Then trimming the plastic crest, which serves the air flow to the floor of the machine. On the "eight" units, the fan electric motor is greater in size.
Removing a ventilating device equipped with two blades. Instead, a node with five elements will be used. Before mounting a new device, it is necessary to distribute the quality of its operation. To do this, the node is connected and checked.
If the device works correctly, it is installed on the installation instead of the old one. After mounting, the node must be qualitatively fixed. This will prevent the negative impact of vibrations during movement and fast failure of the device.
In order for the ventilating unit to function more calmly, it is necessary to replace the resistor element. This is due to the fact that the device allows you to overtake the larger amount of air flow and functions more noisy. Therefore, the resistor element is installed, which can be used from VAZ 2108.
Buttons, as well as the regulatory components of the ventilating device, must be changed to new ones. It is allowed to use parts from VAZ 2108. The regular key from the "seven" is suitable for sizes and fastening. But it quickly fails as a result of a great difference in current. At this stage, the upgrade procedure can be considered completed.

Thermostat refinement

Thermostat from Car Chevrolet Niva

The procedure for finalizing the thermostat on the VAZ 2107 is to replace the standard device to the part from Chevrolet Niva:

First, the reflection of the refrigerant of their cooling system is performed. The engine of the car warms up, the container and the liquid is substituted.
Opens motor compartmentThermostat is dismantled with highways connected to it. It is necessary to turn off the discharge nozzle located below, it comes from the radiator device to the replaceable element. The bypass highway is disconnected, it is installed on top, as well as a hose coming from the thermostat to the pump. The state of these nozzles is estimated. If they are worn or damaged, then you need to prepare new ones.
A disconnection of the reducing refrigerant highway is made, as well as the copper pipe. The last element is unscrewed from the pump, for this you need to unscrew the two nuts and dismantle the flange with the studs.
The bottom removed highway is taken and the middle part is cut out of it. The length of the segment should be about 7-9 cm.
Mounted a new thermostat device. Its connection is performed using a pipe with a water pump. The hose must be a little bend a bit.
Then the thick nozzle from the VAZ 2108 is taken and is adjusted to the place where the lower regular hose was installed. From two ends of the element, you need to cut the same parts and connect it to a new device. In principle, it is allowed to install both the standard highway, but this option is simpler.
The installation of the upper hose is made, we are talking about a regular pipe.
Instead of the dismantled highway, a plug is made, it walked from the heating node to the water pump. This will require a copper tube, a connecting flange is disappeared from it. The sealing element is made from rubber, then the surface of the pipe is treated with a sealant. The design is screwed back to the water pump.
The next step will be the connection of the branch refrigerant nozzle from the heating device with the input on the thermostat. To perform the task, a dismantled copper hose is taken, the extra part is cleaned, then it bends a bit.
The bracket is made to be used to fix the nozzle to the exhaust collector device.
A discharge highway is connected from the heating node with a hose that was disconnected earlier. The output from the stove remains similar, and the input will not go to the pump, but to the thermostat.
The end of the highway is connected to the corresponding input to the thermostatic device, it will take a shorter and curved pipe. It is used to remove the refrigerant from the GBC to the heating node. This element must be adjusted in advance in length. When using an aluminum thermostat, difficulties may occur, since the walls of such devices are thicker. This means that the highway must be used with a large diameter.
The thin pipe of the heating system of the intake manifold device to the most subtle thermostat output is performed. Previously, it is necessary to disconnect the end that goes to the lower line from the heating device to the water pump. The nozzle is measured, an extra part is diverted if necessary. The connection site is processed by sealant. To prevent leakage, the volume of glue should be large.
Then the location of the connections of the nozzles and the thermostat is tightened with the help of clamps. The refrigerant is poured into the heating system. Engine starts. If the system formed an air traffic jam, then it must be removed.

In detail about the installation of the thermostat from the car Lada Grant on the classic models of VAZ told Valery IMenov.

Installing an additional pump

Installation of another pump on the heating unit will ensure the best heating of the cabin in the car. Usually, this device is installed next to the battery and the nozzles in the engine compartment. When performing the task, it is necessary to dismantle one highway coming from the cylinder block. This pipe is connected to an additional pump. From the cylinder block, the highway should go to the front of the water pump, and the outlet tube will be connected to the heating system.

The power supply to the auxiliary pump is taken from the activation key of the rear window heating system. This will allow you to turn on the device together with this node. From the electric motor of an additional water pump there is one positive conductor. Minus contact is a mass of the device.

To ensure power supply, do the following should be done:

Disassembly of the first connector with conductors. Several electrical caps are connected to it. The gray conductor is designed to activate the rear window heating system, this is the main cable.
This wire connects the power cord from the water pump. The cable itself is displayed in the engine compartment through the process hole.
For better fixing of the conductor, the contact element is recommended to solder.
Upon completion of the installation of the pads, an additional water pump is ready for testing and operation.

On the classic VAZ models, the channel "Avtopodohet" told on the installation and features of the addition of an additional pump.

If necessary, connecting the water device can be performed by another method:

To perform the task, you will need a shoe from nozzles or a detonation controller. This element is purchased in any auto shop.
Two conductors sold on the ends of the pads, and then the cables are installed in the corrugation and wrapped with a tape.
Then the electrical power supply is displayed to connect the ground, you can use any conductor available on the bracket near the installation site.
The harness itself is installed up, the resistor elements of the heating unit are connected to the connector where positive contact was taken. This will allow you to automatically activate the water pump that consumes about 1.5 amps during operation. Such a connection method allows not to use additional relays and connect to a positive output in the connector directly.

Many car owners install not "VAZ", but "foreign" pumps on the car. You can use the device model 0392020034 from the Bosch manufacturer. The performance of such a pump is 750 liters per hour, but additionally need to purchase clamps, as well as about 10 meters of corrugations. Before performing the task, it is necessary to drain the refrigerant from the system.

The complexity of the installation of the branded water pump is that the diameters of the hose and fittings of the device do not correspond. The first is 1.6 cm, and on the pump - 2 cm. Therefore, it is recommended to use more elastic hoses. This will pull the highway on the fitting. For a better passing, the element can be treated with engine fluid.

IN winter time The year is increasing the need to heating the salon of the car, and those who deal with independent modifications of their cars are solved on. If you install an additional stove on the VAZ-2107, it will become much warmer in the machine, and less time will leave for heating.

Where to get another stove

As on domestic carsFor example, on the VAZ-2107, it does not allow constantly maintaining a comfortable temperature in the cabin because of the device itself, then drivers can install an additional stove on the VAZ-2107. In fact, if the street is in the street below minus 10, then the radiator is already poorly coping with his task, and only two stoves in the VAZ-2107 will be able to make heating faster.

Most often for additional heating of the cabin, the Chinese production unit is used by 12 volts, with six channels on the right and six channels on the left (3 per fan).

When ordering the second Chinese production, it is necessary to take into account the location of the outlet nozzles that are powered into the system. They will depend on the position of your new heating system when installing.

The system allows the release of air from the cabin with two fans. Speed \u200b\u200badjustment is usually in each device, and it is better to stay on three-step adjustment.

The furnace systems can be not only two, but also one fan with three outlet nozzles. Even such a small additional stove can warm up the interior to plus 25 in 2-3 minutes.

Installation of chinese stove

Installing an additional stove on the VAZ-2107 is very simple. IN additional stove Only fans are powered. Some wire (usually black) must be thrown to the ground. Fans are located in a plastic case, and with the iron of the box itself is not in contact.

Throw wire on the relay that allows you to switch speed. It is usually three-step, and is located on the instrument panel. There is also a pump, and speed-switch buttons. In general, nothing complicated, most importantly, find a place on the instrument panel where you can install your stove.

Another pump

Additional pump on the VAZ-2107 stove is also capable of improving heating in the car. Pump is usually installed next to the battery and hoses. When installing, you must remove one hose that goes directly from the block. Dress this hose to extra pump. From the block, the hose must be departed to the nose of the pump, and the hose on the output is already to the stove.

Power on an additional pump is taken from the heating button of the rear window. From an additional pump engine there is only one plus wire, and the housing itself is mass.

Power supply is carried out simply:

The very first plug with wires is removed, and the second gray wire that is responsible for heating the rear window will be our basis.
It is wrapped with meals from pumps and deposit under the hood.
So that the wire holds reliable, it can be soldered.
After installing the plug, it can be said that the pump is ready to work.

Sometimes an additional pump is made due to weak air circulation. In addition, on small idling Circulation, in general, may be absent, and Tosol to do bad to the stove.

An additional heater on the VAZ-2107 according to the result of the work will be included every time the rear window heating will be turned on.

But you can connect the pump and differently. To do this, you will need a connector from the nozzles / detonation sensor from the VAZ. It can be bought at any auto parts store.

Two wires must be soldered to the ends of the part connector, after which everyone hide everything in the corrugation and flush the tape.

Separately display the wire for connecting the mass. I find it on the bracket nearby. Harness spend upstairs, plug the stove resistors to the block, from where it was taken plus.

As a result, when the heating is turned on, another pump is turned on, which consumes only 1.5 and in operation mode. In this case, you can not install the relay and connect directly to the positive wire in the block.

Possible difficulties

If you do not want to contact the VAZ pump, you can look after the pump from a foreign car. It is suitable, for example, Bosch 0 392 020 034, with a capacity of 750 l / h. And at the same time it is worth buying 10 meters of thin tubing (corrugations) and clamps.

Do not forget to drain all the antifreeze from the system. The complexity of the pump installation is primarily in the inconsistency of the diameters of the nozzle and pump fittings: the diameter of the nozzle is 16 mm, and the pump is 20 mm. If the nozzle is slightly elastic, you can try to pull it on the output fitting.

To the fitting insert into the nozzle, it is worth lubricating it with oil. In conditions of limited space, it is difficult to work, so it is necessary to fix the nozzle of the self-locking clamp, and the clamp on the screed is fixed to the engine support. This will facilitate your work. POMPU BETTER CONNECT CHSEAGES TO THE TUND OF AIR CONDITION.

Work with resistor

In order to be able to adjust the speed of heat intake into the salon, you can install an additional VAZ-2107. Typically, the resistor has two spirals with a resistance of 0.23 and 0.82 ohms.

The new resistor is installed under the gas pedal so that access to it is free. When turning on the stove to the first speed, the current will go through 2 spirals. At the second rate, the current will go through a spiral with a resistance of 0.23 ohms. Past to the resistor current goes when the third speed is turned on.

The resistor is located to the right of the accelerator pedal and is attached to the rear of the air conditioning unit.

Thus, the car will warm up much faster and better. An additional advantage is to reduce the fogging of the glass and air circulation in the cabin. In general, heated air in the car will be more uniform.
