Additional stove for the interior of the VAZ 2107

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.

I decided to make the car warmer. I spent a long time studying the design of a standard stove. I came to the conclusion that there was nothing to catch here. Having removed the stove valve, it became clear that without a radical alteration of the stove, nothing worthwhile could be achieved from it.

Well, I remembered: once, having disassembled the stove, I, in addition to a bucket of dry leaves, found there a barely open damper, tightly rusted in a loop, and a cable torn from it. Having thought about it (yes, like Stirlitz when hit by an explosive bullet in the head), I removed this shutter. The air “by gravity” began to fly into the stove much better; at a speed of >60 km/h, you don’t have to turn on the fan, it blows quite strongly. But this is only enough for a little cold...

Independent production of an additional auto stove

For those who do not want or cannot purchase a “factory” heater for the cabin, we can recommend making the device themselves. To do this, you will need an old computer power supply, a couple of strips of ceramic tiles, powerful wiring, and nichrome springs for the heater.

Step 1. Select a working power supply

This device perfectly warms up the interior of a small car such as a Hyundai or Daewoo. The main thing is not to overdo it with the calculated power, because it is powered by a battery or generator.

Types of additional heating device

If the owner of a Russian vehicle is thinking about how to install an additional heater on a VAZ-2110, then, first of all, he should know that the practical majority of currently existing designs fit directly into the standard cooling system of the power unit. The heated air flow is distributed throughout the cabin by a built-in electric fan.

Additional stove purchased at the store

An additional stove for the interior of the VAZ-2110 can be purchased at the store, however, in order to save money, such a unit can be made with your own hands. In fact, car dealerships sell completely different types of additional heaters. Depending on the budget and preferences of the motorist, you can choose both small and fairly large designs. True, not all presented models can be placed in the top ten without compromising passenger comfort. There is not much free space in a domestically produced car, so when choosing a unit, you should first decide on the location of its future installation.

If the car owner decides to install an additional heater under the passenger seat, then the purchased device should not be wider than 33 cm, higher than 20 cm and have a depth not exceeding 25 cm.

If you choose the optimal location for an additional heater, you should stop in the area of the car located between the seats (the unit will take the place of the tunnel), or directly under the front passenger seat.

Preventing the operation of the stove in the cabin

In order for the car heater to work at full capacity and not let the driver down at the most crucial moment, you need to follow a few simple tips for its operation:

The radiator must be kept clean. The procedure for cleaning light contaminants can be carried out using a vacuum cleaner, and blockages and deposits in the internal channels can be removed by flushing the engine cooling system.
It is necessary to use good antifreeze, which is considered the key to high-quality and long-term operation of not only the stove, but also the car engine.
You need to change the cabin air filter more often. If you do not change it in time and do not remove contaminants, it will create problems when warming up the interior, and, in addition, ventilation and air conditioning in the car interior will not work at full capacity. This procedure is especially recommended for drivers and passengers suffering from allergies.

How to change the stove in a VAZ 2107

Having found out that the heater needs repair, it will require complete or partial dismantling. If there is a problem with the motor, then it is enough to remove the lower part of the assembly. If there is a problem with the radiator, you must first drain the coolant from the engine cooling system. To carry out repair work you will need the following tools:

Phillips and flathead screwdrivers;
set of open-end and socket wrenches.

To replace the stove you will need a set of keys and screwdrivers

Heater removal

After the coolant has drained and the necessary tools have been prepared, you can begin disassembly. It is carried out in the following order:

Remove the negative terminal from the battery.
In the engine compartment, loosen the two clamps that secure the hoses to the heater pipes. When the hoses are pulled together, a small amount of antifreeze will leak out.

Unscrew the clamps and pull the hoses off the radiator tubes

Unscrew the screws and remove the rubber seal

To remove the shelf located under the glove compartment, unscrew the fasteners in the form of screws

To remove the panel with the clock and cigarette lighter, you will need to unscrew the corresponding screws

Disconnect the wires from the cigarette lighter and clock

It is necessary to disconnect the right and left air ducts from the heater

Using a 7 key, unscrew the cable fastener

To remove the lower part of the heater you will need to pry off 4 latches with a screwdriver

After dismantling the lower part, access to the heater fan opens

To remove the radiator, simply pull it towards you.

To completely remove the stove, you need to unscrew 4 10mm wrench bolts.

When the fasteners are unscrewed, remove the upper part of the stove body

Catalytic mini heater

What other ways are there to keep warm inside a car? For example, there are very convenient mini-heaters that will help warm your hands. They are also produced by Kovea. They are very economical and safe and in such catalytic burners heating occurs without flame.

Video about how a catalytic mini-heater works:

The Zippo flameless hand warmer has also proven itself quite well. It is the size of a large lighter from the same company, but it heats well. Interestingly, it was also used by soldiers in the First World War to avoid freezing in the trenches.

Installation locations, connection diagrams

You can purchase an additional stove for the VAZ-2107 or make it yourself. The design of such a heater includes a radiator, which is connected to the cooling system through pipes, and a fan that creates air flow.

If you decide to install an additional heater radiator, first of all decide on the installation location. There are three optimal locations for installing equipment:

Under the front passenger seat
Below the front panel under the glove compartment.
On the center tunnel between the front seats

The location should be selected based on the overall dimensions of the stove.

The next important condition is the connection diagram. You install the additional radiator in series with the standard one (the drain pipe of the standard one acts as an inlet for the additional one). The disadvantage of this connection is the weak heat transfer from the other heat exchanger, since it will receive antifreeze, which has already given off some of the heat.

An additional stove can be connected in parallel to the standard heater (the supply and drain of the second radiator cut into the corresponding pipes on the main stove). The negative side here is the likelihood that the main flow of liquid will flow only to one radiator; in this case, the second one will heat poorly.

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

You can improve the operation of the heating system on the “seven” in the following ways:

redo side window ventilation;
modernize the damper;
modify the foot airflow system to increase its efficiency;
improve the operation of the rear cabin heating system;
modify the thermostat;
improve the functioning of the steam exhaust line;
install an additional water pump.

User Egor Panther spoke about options for upgrading the heating system in VAZ 2107 cars.

Improved side ventilation

The side ventilation system needs to be modified after purchasing an additional fan. The device is mounted in the left line, which will allow forced air flow to the deflector.

The tuning procedure looks like this:

At the first stage, the deflector device is dismantled from the main line. To perform this task you need to use a screwdriver. The deflector in the cabin is pryed up and removed; it must be pulled forward. Similar actions are performed on the other side of the stove.
Dismantling the device is carried out carefully so as not to leave any traces of damage on the center console.
If the deflector is removed, it is necessary to remove the holding device from the dashboard. This element is mounted in the center console using special antennae. The essence of this modernization is that a classic computer fan is installed to force air flow into the heating system.
To install the ventilation device, the element must first be fitted to the deflector body. After applying it to the plastic with a marker or pencil, you need to apply markings. Using a utility knife, a cut is made in the plastic on the deflector.
If the dimensions are marked accurately, the ventilation device will be tightly installed in the housing. This is important, since such installation will prevent the part from loosening while driving.
After completing the installation of the fan, you need to make sure that its blades rotate normally and nothing interferes with them. If problems arise, the device is adjusted. If necessary, the blades can be trimmed a little.
To ensure efficient air flow and no backdraft, the entire structure must be sealed. Therefore, using sealant or the remains of plastic that appeared after cutting the deflector, the cracks are clogged.
If all steps are completed, the ventilation device is installed in the main line area, and then mounted on the body of the deflector element.
After completing all the installation steps, you need to work with the electrical component. It is recommended to connect the fan electrical circuit to the conductor where the current appears when the ignition is activated. This option is more convenient. It is possible to connect the device to the heating unit control cable.

Types of additional heaters

The driver can choose the most suitable option from several types of heaters. They differ in installation method, energy consumption, cost and appearance.

Electrical devices

The simplest type of additional heating. It is plugged into the car's cigarette lighter and is most often mounted on the front panel. For its low cost, young motorists love it. More experienced drivers try to use it less often, and only as a hair dryer to warm up the glass.

Positive properties:

low cost of the device;
simple installation that does not require the involvement of third-party specialists from the station;
power comes from a battery or generator, without wasting fuel;
ready for use immediately after switching on;
has neutral colors and discreet shapes, which makes it easy to fit into salons of any color;
Available at almost any auto store.

Negative properties:

there are a large number of low-quality cheap fakes that can be dangerous during operation;
in high modes it consumes a lot of electricity, and with prolonged use of the battery it can quickly discharge it;
negatively affects electrical wiring, so it is recommended to connect it directly with more powerful wires.

Autonomous heaters

Most often, such an additional stove in the cabin is installed on minivans, minibuses, residential vans or trucks. Its power comes from fuel. The stove is equipped with an independent combustion chamber and exhaust pipe. Because of this, it is mounted outside the passenger compartment in the engine compartment. The operation of the device does not depend on the motor and is therefore called autonomous.

Positive properties:

the performance of the unit does not depend on the degree of heating of the power plant;
there is the possibility of adjustment from the cabin;
does not change the interior of the car;
ready to work immediately after startup;
high recoil power.

Negative properties:

more complex installation is required than when installing an electric heater;
additional fuel consumption occurs when the heater is operating;
the cost is higher than that of an electric heater;
additional noise appears from the operation of the device.

Additional radiator

Many people install another radiator in the rear of the cabin. It is connected as a serial device in the cooling circuit together with a standard stove. To do this, pipes are passed through the cabin, and then a radiator with a fan is attached.

Repair and replacement of individual heating system elements

In addition to the radiator, the heating system includes a fan with an electric motor, a tap and a control unit.

Drivers who have been driving Zhiguli cars for many years often say that the VAZ 2107’s stove sometimes does not heat well. The most common cause of malfunctions in a system such as the VAZ 2107 stove is a leak in the radiator, as well as in pipes, taps and connections located directly between them. To this can be added switch failures for electric fan modes, damage to the device wires or oxidation of their components.

Fan motor

The electric motor of the stove is considered one of the weakest points of the VAZ 2107. This is due to the material of the bushings on which the rotor rotates. When these bushings wear out, the fan operation is accompanied by a characteristic whistle. This happens after two to three years of using the car. The electric motor can be brought back into working condition by cleaning and lubricating. However, after a short time the whistle from the stove fan will appear again. In such cases, experts recommend replacing the standard electric motor with a new one - a bearing one . As a result, the whistle will disappear, and the reliability of the unit will increase. The replacement process is associated with certain difficulties, since the electric motor is located in a rather inaccessible place. Nevertheless, after installation, the bearing motor is guaranteed to work for several years.

Heater valve

The heater valve is replaced when it jams, leaks, or in other cases when repair is impossible. Experts recommend installing a ceramic faucet in this case.

The metal heater valve usually opens in the fall and closes in the spring. During periods of inactivity, it can sour, become covered with scale and simply fail. The result can be extremely unpleasant for the car owner. These disadvantages do not exist with a ceramic faucet. There is practically no scale accumulation on ceramics, and it is not subject to corrosion. As a result, even after a long period of inactivity, the heater valve will be in working order.

Installation of an additional stove in the interior of a VAZ-2110

Before installing a new heating element in the vehicle interior, you should decide on the sequence of actions to be performed. The installation process of an additional stove can be divided into several main steps:

securing the heating unit under the front passenger seat;
depressurization of the power unit cooling system;
connecting the durite hoses of the installed device to the section of the engine cooling system (it is important to follow one rule: the hoses of the new stove should not come into contact with the muffler pipe and steering parts);
drilling two small holes in the engine shield, about 19 mm in diameter (this is necessary for the pipes of the new heater);
location of the heater pipes in the cabin under the floor covering;
removal of pipes close to the seat frame for the passenger;
installation of fasteners that help fix the pipes on the auxiliary heater;
filling the expansion tank with about a couple of liters of antifreeze or antifreeze;
removing the air lock from the engine cooling system;
creating a button on the dashboard through which the car owner can remotely control the new heating element.

To install an additional heater VAZ-2110 it will take about 4 hours

If an additional pump is installed along with the new stove, this will help make the heater more productive, because the additional stove uses the flow of antifreeze, which is pumped only by the standard pump.

As a rule, it will take about four hours to install a purchased or homemade additional heater for a VAZ-2110.

Advantages of an additional stove

Experienced motorists note the fact that an additional heater installed in the cabin helps warm the space to a comfortable temperature 2 times faster. At the same time, the feet of passengers sitting behind will always be warm.

The additional heating device does not affect the beauty of the interior; the unit does not spoil the appearance or interfere with the passengers’ feet.

The additional heater does not interfere with passengers' feet

Disadvantages of a new heater

Although the updated heating makes the temperature inside the car higher than usual, it has some disadvantages. In particular, antifreeze or antifreeze begins to warm up more slowly, which occurs due to an increase in the heat capacity of the engine cooling system.

In addition, additional noise emitted by the new heater appears in the cabin, and dust on the floor rises up along with the flow of heated air.

In the summer, hot hoses located under the floor covering can be especially inconvenient, as they will begin to heat up the interior. True, the situation can be corrected by installing a small tap in the engine department, which should be carried out at the stage of “insertion” into the engine cooling system. It is worth noting that there is no such device (faucet) in the finished heater.

When installing a heater, additional noise appears in the cabin

If the speed of the additional heater is not adjusted, one part of the cabin will warm up more, due to which the passenger sitting in this place may feel discomfort.

Creating a homemade additional heater

You can make a homemade additional heater for a VAZ-2110 from an old heater radiator of any other car.

The stove has lost efficiency - reasons

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

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

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

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

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

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

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

Trouble-shooting

As practice shows, in most cases, a malfunction of a car’s heater is a consequence of problems with the thermostat, so drivers are advised to check it first and, if necessary, replace it with a new one. In other cases, if the stove is not working properly, you should do the following:

Check the antifreeze level in the expansion tank and add it if necessary.
Before driving, make sure there are no coolant leaks under the tank.
Sometimes exhaust gas analysis can help determine the location of an antifreeze leak. If the gas has a whitish tint, the leak may be coming from the exhaust pipe.
Check the operation of the fan with the engine running; if there is noise, have it inspected by a specialist.
If there are unfamiliar odors in the interior, you should check for antifreeze leakage inside the car.
You can also check the temperature of the radiator by touch; a cold radiator indicates that it is clogged.
If there is a climate control function, computer diagnostics should be performed.

Basic malfunctions and ways to eliminate them

The most typical malfunctions of the VAZ 2107 stove include:

Air entering the cooling system. This usually happens after the system has been filled with antifreeze. Removing the airlock normalizes the heating process of the interior.
When the heater tap is open, coolant does not flow into the radiator. This most often occurs when water is used as antifreeze. Scale forms in the system, clogging the faucet and impeding the passage of coolant. The problem is eliminated by dismantling the tap and then cleaning or replacing it.
Poorly functioning or failed water pump. If the pump does not pump coolant, this can lead not only to a lack of heating of the interior, but also to more serious problems, such as engine overheating. The water pump does not work, as a rule, when the generator belt breaks, as well as when it jams as a result of wear on the bearings.
Clogged stove radiator honeycomb. In this case, the supply pipe will be warm and the outgoing pipe will be cold. The radiator often becomes clogged when water is used as a coolant, as well as when oil or additive particles enter the system to eliminate leaks. Cleaning or replacing the radiator will help restore normal operation of the stove.
Displacement of the partition in the radiator. If both radiator hoses are hot, but warm air does not enter the cabin, then most likely the partition in the radiator has shifted. The only solution to the problem is to replace the radiator with a new one.

Method thirteen - well, this is absolutely for extreme sports enthusiasts!

If you often find yourself in situations where you have to fight the cold in the car (for example, you are a traveler), then you can take a regular wood stove with you on the road. If you don't believe me, look:

A real oven in the car

So how? Did you believe it? You can stock up on firewood or brushwood for free, for example, if your forced stop occurred in the forest or next to an old and dilapidated building with a lot of boards.

If your car stalls in winter, don’t despair. Armed with any of the heaters listed above and having studied all the tips described, you will not freeze and survive in harsh weather conditions. Even if you find yourself in a car at night, face to face with a cold and harsh winter, you can create all the conditions in the cabin that are similar to the comfort of home. So, don't worry, motorists!
