Installing the radiator grille VAZ 2107

How to modify the stove on a VAZ 2107 car with your own hands

It should be recognized that classic models of domestic cars, which include the VAZ 2107, have certain design flaws.
But this, in turn, provides their owners with a wide field of activity in terms of modifications in accordance with their needs. At the same time, something made by yourself is often more effective than a factory one. Many owners are dissatisfied with the operation of the interior heater or stove. Indeed, VAZ 2107 cars have very low stove efficiency. But modifying the stove yourself can solve this problem. In this case, there is no need to use special skills or tools; improving the heater is done using improvised means.

As practice shows, the stove radiator gives off a sufficient amount of heat and its improvement is not required. This means that to increase the efficiency of the heater, it is necessary to improve the airflow system. First of all, care should be taken to seal all air ducts, especially at their connections. This requirement is especially true for VAZ 2105 - 2107 cars, due to the design features of the air ducts.

The simplest tuning, which does not require virtually any design changes, is replacing the standard fan motor with the one used in the VAZ 2108-2109. The motor used in these models differs from the seven in greater power and increased speed. To install it, you will need to slightly modify the stove body - due to its larger size, you will have to remove the comb designed to direct the air flow down to the feet.

You can leave the original impeller by first drilling a hole with a diameter of 7 mm in it for the shaft of the figure-eight motor. Performing this operation with your own hands is absolutely easy.

Such a stove modernization will also require replacing the resistor and switch. We take both parts from the same model as the motor. Please note that tuning will be effective if all of the above requirements are met. After all, the VAZ 2107 switch is designed for a lower current, and when used with a more powerful engine it can simply melt. But the native resistance of the VAZ 2107 will not allow using the engine at full power.

For car enthusiasts who are accustomed to not being afraid of difficulties, and for whom tuning a car with their own hands has become commonplace, there is a more effective, but also more complex way to improve the stove. It consists of installing a snail impeller instead of an engine used in VAZ 2108-2109 models. This tuning will significantly reduce noise and increase air flow.

Refinement begins with complete disassembly of the heater housing. After dismantling, almost everything is cut off from the bottom of the stove, except for the frame and fasteners. Next, you need to make a housing for the snail. For this purpose, you can use any material suitable for strength - plexiglass, polycarbonate, plastic, etc. All four walls of the future housing are cut out of it and screwed to the bottom of the stove.

After this, the middle part is put on the lower part, with the diffuser previously removed. The dimensions must be adjusted so that the snail fits exactly into the body and does not protrude beyond the radiator stops located on the middle part.

This stage of work requires special attention, since the body is too large and will not allow the stove to be installed in its normal place. After careful adjustment, making sure that the dimensions of the new body are correctly selected, all joints are coated with sealant.

All that remains is to tune the air ducts. For this purpose, you can use commercially available plumbing cuffs and hoses. Holes corresponding to the outer diameter of the cuffs are cut on both sides and in the bottom of the new stove body. Plumbing hoses are inserted into them - the side ones are connected, respectively, to the left and right air ducts, while the bottom ones are designed to remove warm air away from the feet, otherwise they will be excessively heated by the direct air flow.

To warm the feet of rear passengers, you can additionally install an additional pair of longer hoses. The power of the snail and the amount of heat given off by the stove radiator are quite enough for everything. The connection points between the hose and the side air ducts must also be carefully sealed to prevent leaks of warm air.

Such tuning, done by yourself, will increase its efficiency by 2-3 times, both in terms of heating the interior and in terms of the quality of glass blowing. After all, it is precisely the insufficient flow of warm air that does not prevent fogging of the windows of VAZ 2107 cars. At the same time, modernization does not require significant costs and is accessible to everyone.

It should be remembered that installing a snail, just like replacing an engine, requires replacing the switch. In addition, you need to make sure that the fuse installed in the stove circuit has a rated current sufficient for the operation of the modernized stove. Before the final installation of a do-it-yourself structure, it is recommended to turn on the electrical equipment of the stove directly to make sure it is working and connected correctly.

How to make a VAZ 2101 stove

Let's not make any big background stories, but let's get straight to the point. Previously, when I had already come across similar articles, the good advice there was to seal all existing connections in order to avoid air loss. This is partly good advice, but partly not, it doesn’t always just help. What to do in this case?

I would like to tell you about the improvement of the source of that very air supply, namely the fan. The radiator itself gives off more heat; there is simply not always enough air to heat the entire interior of the car. To solve this problem, it is worth operating the engine from the heater fan on a VAZ 2108 or VAZ 2109.

This is due to the fact that the standard VAZ heater engine produces only approximately 3000-3200 rpm and consumes a current of 4.5 A, and the “chisels” have, in some respects, more powerful engines that are capable of delivering approximately 4000 rpm minute, but also consume significantly more - 14 A.

As you can see, the consumption is very large, but at the same time the air flow is completely different, which is the fundamental issue in our case. What are we doing?

We disassemble and modernize the VAZ 2101 - 2107 stove

First, let's take everything apart. Next, you need to cut off the comb and then replace the fan speed control resistor. Why was it necessary to cut down the comb? This is explained by the fact that the dimensions of the chisel engine are larger than the usual classic ones. So, in order to completely cover the foot heating, it needs to be cut down. According to calculations, the result may be approximately a couple of times more air.

First, we drill a hole on the impeller with a diameter of approximately 7 mm. To do this, you should put the impeller on the shaft of the “seventh” engine as tightly as possible, it is advisable to experiment until the noise and vibration are completely eliminated. Before installation, do not forget to perform a test run and only then continue to work.

A question may also arise in terms of “why was it necessary to replace the resistor to switch speed modes?” The answer is simple (it is replaced after testing) with its help a greater air flow is supplied. You also need to remember to replace the fan rotation mode switch, since it is simply not designed for high current and often simply melts.

It is connected according to the usual scheme from a VAZ 2108, in short, you get a regular 3-speed switch, which is activated when the ignition is active.

How to improve the stove VAZ 2101 - 2107 (video)

Warming up of the interior is carried out much faster and, accordingly, the windows thaw faster; with an increase in efficiency, the interior immediately becomes warmer, even in such a large interior as in the VAZ 2104 there is rarely a need to turn on the heated rear window. There is, of course, a minus - the noise increases when such a fan operates, but this is understandable and tolerable. You can also flush the stove radiator, this will significantly improve its heat transfer.

Heater modernization

Every car owner knows that on a VAZ 2107, replacing the heater may be due to its poor performance. But not everyone decides to change the heater - most owners of the “Seven” decide to disassemble, repair, tune and remake the heater as a whole. There are many schemes for tuning and repair, but you need to take into account that it is not so easy to implement them at home. Without any problems, you can seal the joints of the system lines with nozzles with your own hands, and also redistribute the air flows according to need (the author of the video is VAZ 2101-2107 REPAIR AND MAINTENANCE).

However, such a modification of the stove will not improve the microclimate in the cabin. If you want the air in the cabin to be warmer, you will need to increase the air flow with a new radiator, since the factory device will not allow this idea. Fan replacement is also necessary in such cases. The best option would be to install a V8 electric motor.

So, the repair and tuning scheme for the heating system is as follows:

1. First you need to know how to remove the stove. You are required to dismantle the lower part of the structure, namely the casing on top of which the fan is installed; the latter can be dismantled.
2. After removing the fan, you should carefully cut off one of the so-called ridges that supply air flow to the feet of the front passenger and driver. This is done necessarily, since the electric motor from the “eight” is much longer.
3. The impeller is dismantled. Inside this element, it is necessary to increase the diameter of the hole into which the shaft must subsequently be carefully installed. Make sure that the new structure can fit into the installation location as securely as possible.
4. Before installing a new fan, diagnose its functionality.
5. The resistor should be replaced, since it is thanks to this element that the fan will operate much quieter. As practice shows, it is best to install a resistor from the same “eight”.
6. The vent switch should also be replaced. When the heating system is operating, another current will begin to flow to it. Accordingly, over time this button may fail.

Sorry, there are no surveys available at this time.

Instrument panel tuning

From this video, you will learn how you can make a backlight for the instrument panel of a VAZ 2107 car with your own hands.

Like other elements of the VAZ 2107, the standard instrument panel was ugly and, most importantly, not comfortable. After all, everyone knows perfectly well how the instrument panel is illuminated in foreign cars, everything flashes and sparkles in different colors.

And in this car, even at night you won’t be able to look at the speed at which you are moving, because you simply won’t be able to see it. Therefore, many car enthusiasts, after purchasing, decide to bring the instrument panel into decent shape.

For this type of transformation of the appearance of the car, you will need a few things that will not cost much. First of all, you will need to purchase LED flashlights in different colors, which you can choose to suit your taste.

An overlay for the instrument scale, it will certainly not cost you much. Arrows that will point you to a certain number. And basic tools, starting with a soldering iron. Everyone should know the fact that, first of all, it is worth disassembling the instrument panel.

The next step in remaking the instrument panel will be to remove the arrow. Here you need to be extremely careful, because this work is not so simple. The main task when removing the arrow is not to bend the pin on which the arrow should be located.

Next comes the simplest job, which is to unscrew the number scale. Next comes not a simple collaboration with a soldering iron, here you need to work carefully so as not to solder anything unnecessary.

After completing all the work, it is worth taking a closer look at the color of the diodes, because it may be too bright and noticeable when driving. If you suddenly don’t like it, you can adjust the whole thing by adding or subtracting spots of diodes and numbers.

Bumper tuning

Modernized bumper VAZ 2107
At first glance at the bumper, both rear and front, of this car, you can say that it is not durable, but it is. Not only is it not durable, but it also does not fit into the design of this car.

The bumper is made of simple plastic, on which a chrome plate is applied. The bumper also has a gap between it and the body, which is five centimeters. An excellent solution for the owner of a VAZ 2107 would be to purchase and install a new bumper, both new and old.

You can also improve it yourself, but it will take quite a long time and in the end nothing beautiful will come of it.

Modernization of VAZ 2107 headlights

This tuning in this car will be more noticeable than all others, but only if it is done well. Most car enthusiasts completely replace standard headlights with newer, more beautiful and high-quality ones.

You can also simply change some parts of the factory headlights, and they will become more beautiful.

Fan replacement

Dismantling

The fan assembly procedure is as follows:

1. The lower heater regulator must be moved to the extreme position towards the passenger. The control panel and the glove box with shelf are removed. It is also necessary to remove the center console with the audio system.
2. Using a wrench, unscrew and remove the rod designed to control the damper. Unscrew the nut securing the system radiator skin, as well as the nut located behind the glove box.
3. Disconnect the air line attached to the casing of the radiator unit and remove the fan casing, as well as the device itself.
4. Pull out the rubber seals and disconnect the red cable.
5. Using a screwdriver, you need to remove the retaining ring, which is located on the drive shaft. You should also remove the fan impellers and adjusting rings.

Repair

A disassembled fan must be repaired or replaced with a new, more powerful one, but experts do not advise doing this, since the heating system will have to be completely improved. As for the repair itself, this procedure will not take much time, since all actions associated with it only involve removing and assembling the mechanism. In general, there is nothing difficult about this - if you need to replace the impeller or electric motor, this can be done without problems.

Assembly

How to assemble the device:

1. First, the adjusting rings are mounted along with the impeller.
2. The retaining rings are installed and the red wire is connected back.
3. The ventilation device is mounted at the installation site and secured with brackets.
4. The central part of the console with the audio system is connected.
5. The glove box, control panel, and shelf are put in place.

Features of modernizing the VAZ-2107 stove

VAZ cars, despite their age, are still popular among car enthusiasts. Based on the number of shortcomings of domestic cars, owners are forced to resort to improvement and modernization of certain elements of vehicles. This article will talk about tuning the VAZ-2107 stove, since it is the weak link of the vehicle.

Everyone knows how important the heating system of a car is for the comfort of the driver and passengers during cold winter periods. Freezing windows and cold in the car create great discomfort. Let's look at the main options for improving the vehicle's stove.

VAZ 2107: DIY suspension tuning

Today, tuning the “Seven” suspension is a hot topic, given the large number of owners of this car.

Owners of 2107 in most cases dream that their car’s suspension will become like a sports car.

To achieve a similar result, you will have to replace all the structural elements of the suspension with more modern ones.

The minimum task is to replace the standard shock absorbers and springs. At the moment, there are many spare parts from various manufacturers.

For example, many people prefer Koni, because its spare parts have a relatively low cost, while being of excellent quality

To install sports shock absorbers and springs, you don’t have to go through the hassle of modifying the standard ones, which eliminates many problems.

During tuning, you can think about silent blocks. Polyurethane is popular in this area.

A fairly stiff suspension, obtained by installing new sports shock absorbers and springs, can “destroy” old rubber bands and silent blocks in a short time.

As for polyurethane, in this case it will be able to show its best side, since it can withstand significant loads without problems, resists the effects of springs, and significantly improves the controllability of the machine.

At the end of the above operations, it is necessary to deal with the ball joint. Every car enthusiast knows that after installing polyurethane, the ball joint experiences quite a heavy load.

One of the solutions is the Plaza Sport ball, where sports functionality is optimally balanced.

Reasons for poor-quality heating of the VAZ-2107 interior

To solve the problem, it is necessary to eliminate its original source. Therefore, before we talk about options for improving the heating system of the seven, let’s look at the causes of problems with the heating of the vehicle.

The main reasons for poor-quality heating of the VAZ-2107 interior are most often:

1. Leaking heating system faucet;
2. Low level of air supply from the deflector;
3. Loud operation of the heating system engine;
4. Poor quality supply of warm air to the car interior.

Based on the above reasons for stove malfunctions, we can conclude that in order to improve its operation, it is important to modernize the faucet and baffles, troubleshoot the radiator and improve the operation of the fan.

As you can see, not very serious alterations can make it comfortable for passengers and the driver to stay inside the car. It is important that upgrading the stove does not require significant experience and can be carried out independently by the car owner without the help of professionals.

Do-it-yourself options for improving the VAZ-2107 stove

Let's look at how to improve the operation of the domestic seven heating system exclusively on our own.

We begin the modernization of heating elements by replacing the standard faucet with a more reliable product. The tap is located in the front part of the car in the passenger foot area. Sometimes, car owners find out about its location only in the event of a coolant leak. Leakage causes a lot of trouble for the owner, especially in cold weather. Antifreeze leaks out under the passenger's feet, and not only the carpets, but also the upholstery of the car has to be dried. Coolant also contains substances that adversely affect human health. It is important to fix the leak as soon as possible.

Replacing a conventional faucet with a similar new product helps solve the issue only for a short period of time. Experts advise several options for solving this problem. Alternatively, you can replace the standard tap of the machine with a curved sealed tube. Thus, leaks are eliminated, however, another inconvenience arises. The absence of a tap does not make it possible to shut off the supply of coolant to the heater radiator. In summer it will be very hot inside the car. A more acceptable solution to the issue is to install a conventional water tap to supply antifreeze to the heater radiator in the engine compartment of the car. The only inconvenience with such an upgrade will be the need to open the hood of the car to manipulate the tap.

Another drawback in the operation of the VAZ-2107 heating system is the poor quality of the deflector, which is located on the driver’s side. This causes the glass to fog up, which impairs the driver’s visibility and can cause an accident. To improve the performance of the deflector, it will be improved by installing a small fan in it. Most often, spare parts from computer equipment are used for this. For installation, you need to remove the deflector and prepare a place in it for installing the fan. It is better to connect the fan power supply to a separate button, which will be more practical to use.

The next stage of tuning is troubleshooting the radiator. On the VAZ-2107, oversized copper or aluminum radiators were most often installed. The reason for their poor performance can most often be the occurrence of blockages in the heating system. To improve heating of the vehicle interior, it is necessary to completely clean the radiator and parts of the cooling and heating system. It is important to use high-quality coolants for the car and not to use water instead of antifreeze. This way, you can protect your heating system from leaks and blockages.

The most radical and effective way to modify the VAZ-2107 stove with your own hands is to replace the standard fan with a similar product from the domestic eight. This option will increase the heat supplied to the vehicle interior by the radiator and improve its heating. Figure 8 fans are characterized by a higher rotation speed and low energy consumption. To install a new product, you need to disassemble the lower part of the stove to get to the fan and dismantle it. It will no longer be needed in the future. To install a figure-of-eight fan, you need to trim the ridge that is responsible for supplying air to the floor of the car. A more powerful figure-eight fan with five blades is installed in place of the standard product. It is very important to secure it securely. For correct operation of the fan, it is advisable to also replace the resistor and regulators with similar products from the VAZ-2108. And also the fan switch button must be replaced with a button from the VAZ-2108. The standard seven button can quickly burn out due to the difference in the current supply.

At this point, the modernization of the stove can be considered successfully completed.

How to install an additional stove on a VAZ-2107

In the winter season, the need to heat the car interior increases, and those who independently modify their cars decide to tune the heating system. If you install an additional heater on the VAZ-2107, the car will become much warmer, and it will take less time to warm up.

Where can I get another stove?

Since on domestic cars, for example, on the VAZ-2107, the heating system does not allow you to constantly maintain a comfortable temperature in the cabin due to the device itself, drivers can install an additional heater on the VAZ-2107. In fact, if the temperature outside is below minus 10, then the radiator is no longer doing its job well, and only two stoves in the VAZ-2107 can make heating faster.

Most often, for additional heating of the interior, a Chinese-made 12-volt device is used, with six channels on the right and six channels on the left (3 for each fan).

When ordering a second stove for a Chinese-made VAZ-2107, you must take into account the location of the outlet pipes that feed into the system. The position of your new heating system during installation will depend on them.

The system allows air to be drawn from the passenger compartment using two fans. Speed ​​control is usually found in every device, and it is better to choose a three-stage control.

Furnace systems can have not only two, but also one fan with three outlets. Even such a small additional stove can warm up the interior to plus 25 in 2–3 minutes.

Installation of a Chinese stove

Installing an additional heater on a VAZ-2107 is very simple. In the additional stove, only the fans are powered. One wire (usually black) must be connected to ground. The fans are located in a plastic case and do not come into contact with the hardware of the box itself.

We throw a wire to the relay, which allows you to switch the speed. It is usually three-stage, and is located on the instrument panel. The pump and speed switch buttons are also located there. In general, nothing complicated, the main thing is to find a place on the instrument panel where you can install your stove.

Another pump

An additional pump for the VAZ-2107 stove can also improve heating in the car. The pump is usually installed next to the battery and hoses. When installing, you need to remove one hose that comes directly from the unit. Connect this hose to the additional pump. The hose should go from the block to the bow of the pump, and the outlet hose should go to the stove.

Power for the additional pump is taken from the heated rear window button. There is only one positive wire coming from the additional pump motor, and the housing itself is ground.

Powering the pump is simple:

1. The very first plug with wires is removed, and the second gray wire, responsible for heating the rear window, will be our basis.
2. We wind the power from the pump to it and bring it under the hood.
3. To keep the wire more secure, you can solder it.
4. After installing the plug back, you can say that the pump is ready for use.

Sometimes an additional pump is installed on the VAZ-2107 stove due to poor air circulation. In addition, at low idle speeds there may be no circulation at all, and the flow of antifreeze to the stove is poor.

Based on the results of operation, the additional heater on the VAZ-2107 will turn on every time the rear window heating is turned on.

But you can connect the pump in another way. To do this, you will need a connector from the injectors/knock sensor from the VAZ. It can be purchased at any auto parts store.

It is necessary to solder two wires to the ends of the connector of the part, after which everything is hidden in the corrugation and sealed with electrical tape.

Separately we bring out the wire for connecting the ground. We find it on a bracket nearby. We carry the harness up, connect the heater resistors to the block, where the plus was taken from.

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

Possible difficulties

If you don’t want to deal with a VAZ pump, you can look at a pump from a foreign car. Suitable, for example, is BOSCH 0 392 020 034, with a capacity of 750 l/h. And at the same time it’s worth buying 10 meters of thin tubing (corrugations) and clamps.

Be sure to drain all antifreeze from the system. The difficulty of installing the pump is primarily due to the discrepancy between the diameters of the pipe and the pump fittings: the diameter of the pipe is 16 mm, and the diameter of the pump is 20 mm. If the pipe is a little elastic, you can try to pull it onto the outlet fitting.

To insert the fitting into the pipe, it is necessary to lubricate it with oil. It is difficult to work in confined spaces, so it is necessary to secure the pipe with a self-locking clamp, and fix the clamp on the screed to the engine support. This will make your work easier. It is better to secure the pump with ties to the air conditioner pipe.

Content

Despite a decent number of shortcomings, VAZs remain loved by our compatriots. Today, we will tell you how to improve the operation of the stove on the classic. The heater and ventilation provide a favorable atmosphere inside the car. In the VAZ 2107, air is supplied from the street. Air, through gaps in the hood of the car, enters the inside of the car. At the same time, depending on the setting, it heats up or cools down.

The air intake box is located in the rear part of the engine block; the air is purified from moisture. The box is protected from the engine by special (rubber) gaskets. Moisture comes out, and the air flow enters the heating system. The gaps in the box are closed with a special partition (lid). When driving, part of the air flow exits through devices located above the dashboard.

External tuning of classic VAZ

What we offer for external tuning of VAZ 2101, 2102, 2103, 2104, 2105, 2106 and 2107:

• radiator grilles and bumper grilles;
• side mirrors (including electric ones) and covers for them;
• door handles and door trims;
• eyelashes and overlays for lamps;
• spoilers;
• door moldings;
• alternative optics;
• bumpers;
• and other.

There are many roads, but there is only one way. Mine! Good luck in choosing your direction!

The classic has proven itself well on Russian roads and will probably not go into a well-deserved retirement any time soon. This car is usually used by people with average income. It is quite inexpensive to maintain and has good technical characteristics. It has minor factory defects, which were probably noticed by everyone who operated this car. It is enough to place several people in the cabin, and the car sag noticeably. This indicates a very weak and unfinished suspension.

Of course, it is better and more convenient to do tuning of the VAZ-2107 suspension in specialized workshops, where they can offer various ways to solve this problem. But the main problem, as you know, is finances, so here everyone needs to decide for themselves what to do, depending on their capabilities. Basically they try to do the tuning of the VAZ-2107 suspension with their own hands. In other words, they want to see good results for little money. And in principle this is justified.

It is advisable to do tuning of the VAZ-2107 chassis at the same time. That is, not parts that are aging and will no longer harmonize with new parts. It is better to thoroughly prepare for this matter and strengthen the suspension of your vehicle.

The design of the heating system of the VAZ 2107.

The heating housing is located inside the car. The heater is mounted on a partition with an engine.

• Fan shell.
• Radiator housings, with air supply cover.
• Air distributor.
• Before entering the cabin, the air is heated. This happens with the help of a radiator located inside the case.

The heater radiator is equipped with an inlet and outlet channel. These channels are connected by tubes to the system to cool the machine’s engine. A heating tap is built into the inlet pipe. The tap regulates the supply of cooling liquid. On the dashboard, there is a lever to control the supply of fluid to the car's ventilation system.

The heating system fan is located at the bottom of the radiator. It is equipped with a small engine located inside the body. Thanks to a special device, the fan has the ability to adjust the speed. The onboard fan has two speeds. Switching is done using a switch on the dashboard.

The air exhaust on the VAZ is designed in such a way as to distribute it throughout the cabin. Therefore, air is released into the car interior, onto the windshield and side windows. Using dampers, you can control the air supply to 2107.

Frequent malfunctions of the VAZ stove.

• Violation of the tightness of the radiator or heating tap.
• Malfunction of the fan regulator.
• Wires damaged by oxidation.
• Fan motor malfunction.

Improvement of the VAZ 2107 stove.

Owners of a VAZ 2107 know that the sound of the stove does not mean that it works well. Therefore, we will improve it ourselves. At the moment, the owner of the vase is given a lot of advice on upgrading the stove. Not every one of them gives the desired result. You can seal the air outlets yourself or adjust the air flow. But, in this case, the general situation in the cabin will not change. To increase the temperature in the cabin, it is necessary to increase the heat supply from the radiator. The fan is from the manufacturer and needs to be replaced. The fact is that it is too small and not productive for the VAZ 2107. Refinement takes place using heating parts from 2108.

To reconstruct the heating system, we need a figure eight fan. Its rotation frequency is much higher. At the same time, it requires the least amount of energy.

The procedure for modernizing the heating system of the VAZ 2107:

• In the cabin, remove the shell of the lower part of the heating. On this part there is a standard fan.
• We remove the standard fan. We won't need it in the future.
• We cut off the ridge that supplies air to the floor of the car. This requires improvement; on the eight, the motor is a little longer.
• Remove the fan with two blades. Its function will be performed by a fan with five blades.
• Before installing a new fan, we connect and check it.
• We install a new device in place of the old one. It is necessary to securely fasten the structure in its new location.
• For quieter operation of the fan, change the resistor. The new fan moves a large amount of air and is quite noisy. For this purpose, a resistor from a figure eight is also suitable.
• We replace the fan buttons and controls with new ones. We use one from VAZ 08. The standard button from 2107 will quickly become unusable due to the current difference. The modification has been completed.

After reconstruction, the stove will not become quieter. But at the same time, the comfort in the cabin will increase significantly!

Modification of the heater VAZ 2107

Many car enthusiasts tried to improve the heating of the VAZ 2107 interior with little effort, but they never achieved an effective result. You can, for example, seal the joints of the air duct hoses with the nozzles or somehow redistribute the air flows, but in general the temperature in the cabin remains at the same level. In order for the VAZ 2107 cabin to actually become warm and cozy, you need to significantly increase the supply of hot air through the heater radiator.

But the fact is that the fan on the VAZ 2107 is too small, it cannot create the required flow of warm air into the cabin; it would not hurt to install a more powerful fan in its place, for example, from a VAZ 2108 car. If you compare the fans with each other, you can see: The fan motor from the VAZ 2107 consumes a current of 4.5 A at a rotation speed of 3000 rpm, and on the VAZ 2108 - 14 A at 4100 rpm. Before starting work, you need to mark out the work front for yourself in advance. We remove the lower part of the stove from the interior of the VAZ 2107; it consists of a casing with an electric fan attached to it. We will completely dismantle the standard electric fan; we will no longer need it. The motor from the VAZ 2108 is a little longer so that it fits tightly on the casing; one of the aerodynamic ridges that directs the air flow to the legs needs to be cut off. This will allow the bottom cover to slam shut completely. What to do with the impeller? We'll have to remove it and assign its functions to a five-blade fan, standard for classics. Its efficiency, compared to the “squirrel wheel” of the VAZ 2108, is lower, because its motor is three times more powerful, but the lighter, from an aerodynamic point of view, rotor of the new motor will rotate at a frequency higher than 4100 rpm.

We increase the diameter of the hole in the impeller and carefully insert the shaft from the new electric motor into it. At this stage, you need to ensure that the entire assembled structure falls into place. Before installing a modified heater on a car, you need to try to directly supply power to the motor, thereby checking its functionality. All that remains is to decide on the built-in resistor. Its task is to ensure a “quiet” operating mode for the stove, but as a result, the modified heater blows too much air, causing a strong hum. In this case, it makes sense to change the standard resistor to a resistor from the figure eight. We also install the electric fan switch from the VAZ 2108. The reason for the replacement is that the standard element is not designed for high current and during prolonged operation it will overheat and one day melt. During the cold season, you will immediately feel all the benefits of a modified stove. Attention! Since the air flow is increased by increasing the flow rate, operating the stove at maximum mode will be accompanied by a high noise level. However, when it’s minus thirty outside or even lower, you simply don’t pay attention to this drawback.

Caring for the VAZ 2107 stove.

As a result of prolonged use, the stove radiator becomes clogged. This entails incorrect operation of the heating system. To restore the functionality of the stove, it is necessary to clean it. This procedure does not require much effort and can be easily done with your own hands.

• Pair of clamps
• Pair of rubber seals
• Spanners
• coolant

Operating procedure.

1. Before starting, you must wait until the engine has completely cooled down.
2. We put gaskets under all the tubes (you can use fabric).
3. Remove the clamps securing the inlet and outlet hoses to the engine compartment.
4. Remove the hoses from the tap (substitute a container for liquid).
5. We unscrew the fasteners and remove the seals.
6. We remove the radiator.
7. We replace all rubber seals.
8. We remove the tap and clean the inlet hoses.
9. Using coolant, flush the radiator.
10. We assemble the heating system in the opposite order and check that it is working properly. Carefully check the tightness of all components!
11. If a leak is detected, increase the pressure of the clamps.

Be especially careful when upgrading your car's heating system. Improving the stove on a classic VAZ is a fairly simple, but very productive procedure. If you approach things responsibly, you will definitely get the desired result! Maintain the stove regularly and clean the radiator. Happy modernization!
