Body

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 classics. The stove and ventilation provide a favorable atmosphere in the car. In VAZ 2107, air is supplied from the street. Air, through the gaps in the hood of the car, gets inside the car. At the same time, depending on the setting, it heats up or cools down.

Air intake box - located in the back of the engine block, air is cleaned of moisture. The box is protected from the engine by special (rubber) gaskets. Moisture - goes outside, 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 the devices located above the dashboard.

The device of the heating system VAZ 2107.

The heating case is located in the passenger compartment. The heater is fixed on the partition with the engine.

Components of the stove:

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

The stove radiator is equipped with an inlet and outlet channel. Channel data, tubes connected to the system, to cool the engine of the machine. A heating cock is built into the inlet tube. The valve regulates the supply of liquid for cooling. On dashboard, there is a lever for controlling the flow of fluid into the vehicle's ventilation system.

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

The air outlet to the VAZ is designed in such a way as to distribute it throughout the cabin. Therefore, air is released into the interior of the car, onto the windshield and side windows. With the help of dampers, it is possible to control the air supply in 2107.

Frequent malfunctions of the VAZ stove.

Violation of the tightness of the radiator or heating tap.
Fan controller failure.
Wires damaged by oxidation.
Fan motor failure.

Improvement of the stove vaz 2107.

Owners of the VAZ 2107 know that the sound of the stove does not mean that it works well. Therefore, we will make its improvement with our own hands. On this moment, the owner of vases, is given a lot of advice on modernizing the stove. Not all of them give the desired result. You can independently seal the air outlets or adjust the air flows. But, in this case the general situation in the cabin does not change. To increase the temperature in the cabin, it is necessary to increase the heat supply by the radiator. The manufacturer's fan 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 fan from the eight. The frequency of its rotation is much higher. At the same time, it requires the least amount of energy.

The procedure for upgrading the heating system VAZ 2107:

In the cabin, remove the shell of the lower part of the heating. On this part, there is a regular fan.
Remove the stock fan. In the future, we will not need it.
We cut off the comb that supplies air to the floor of the car. This requires refinement, on the figure eight the motor is a little longer.
We 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 fix the structure in its new place.
For a quieter operation of the fan, we change the resistor. New fan, overtakes a large amount of air and is quite noisy. For this purpose, a resistor from the eight is also suitable.
The buttons and controls of the fan are replaced with new ones. We use from VAZ 08. The standard button from 2107 will quickly become unusable due to the current difference. The work has been done.

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

Caring for the stove VAZ 2107.

As a result long-term operation, the stove radiator is 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 significant effort and is easy to do with your own hands.

Materials:

Pair of clamps
Pair of rubber seals
Spanners

Operating procedure.

Before starting, you must wait until the engine has completely cooled down.
Under all the tubes, we put gaskets (you can use a cloth).
Remove the clamps securing the inlet and outlet hoses to the engine compartment.
We remove the hoses from the tap (we substitute the container for the liquid).
We unscrew the fasteners and remove the seals.
We remove the radiator.
We replace all rubber seals.
Remove the faucet and clean the inlet hoses.
Using coolant, flush the radiator.
We assemble the heating system in the opposite order and check the serviceability of its operation. Carefully check the tightness of all components!
If a leak is detected, increase the pressure on the clamps.

Be especially careful when upgrading your vehicle's heating system. Furnace upgrade classic vase, a fairly simple, but very productive procedure. If you approach the matter responsibly, you will definitely get the desired result! Regularly look after the stove and clean the radiator. Happy upgrading!

Efficient operation of the car heating system is important at any time of the year, but especially in winter period. The occurrence of malfunctions will negatively affect the comfort of driving in general. Refinement of the stove on the VAZ 2107 is relevant for this car model, since the operation of the heater in them is weak point.

Scheme of the heating unit VAZ 2107

Three levers are used to control the heating system:

The top one is designed to supply refrigerant to the radiator assembly. This slider is connected to the faucet via a cable. It is mounted on the input line. In the extreme left position, the device does not work and the heating unit does not heat. If it is transferred to the right state, it will open and the refrigerant will enter the radiator device.
In the middle position, the air flow dampers can be controlled. If the slider is moved to the left state, the air supply from the street is blocked. It will only circulate inside the car. When moving to the extreme right position, air enters from the street into the car.
In the lower state, the damper is controlled, which is designed to distribute the air flow to the blowers. In the extreme left position, the flow enters side deflectors and in the center, and in the right - on the windshield.

Each of the listed levers can be set to any state, this will achieve optimal functioning of the heating unit.

Disadvantages of the heater in the VAZ-2107

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

Poor rear airflow. Because of design features, warm air hardly reaches the passengers sitting in the back. It will take time to effectively warm up the entire interior of the car.
From the left deflector device on the "sevens" there is a weak air flow.
The electric motor of the heating unit is too loud.
The faucet of the radiator device is also considered a weak point. With prolonged use, it leaks, which leads to a decrease in the amount of antifreeze in the system.

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:

alter the side ventilation of the windows;
make a damper upgrade;
to refine the system of blowing the legs in order to increase its efficiency;
improve the operation of the rear compartment heating system;
modify the thermostat;
improve the functioning of the steam outlet line;
install an additional water pump.

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

Improved side ventilation

It is necessary to modify the side ventilation system after purchase additional fan. The device is mounted in the left line, which will force the air flow to the deflector.

The tuning procedure looks like this:

At the first stage, the deflector device is dismantled from the highway. To perform this task, you need to use a screwdriver. The deflector in the cabin is hooked and removed, it must be pulled forward. Similar actions are performed on the other side of the stove.
The dismantling of the device is carried out carefully so as not to leave traces of damage on the center console.
If the deflector is removed, it is necessary to remove the holder device from the dashboard. This element is mounted in the center console using special antennae. The essence of this modernization lies in the fact that a classic computer fan is mounted to force the air flow into the heating system.
To mount the ventilating device, the element must first be tried on to the deflector body. After applying to the plastic with a marker or pencil, markup must be applied. Using a clerical knife, a cut is made in the plastic on the deflector.
If the dimensions are accurately marked, the ventilator will fit snugly into the housing. This is important, since such installation will prevent the part from dangling 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 there are problems, the device is adjusted. If necessary, the blades can be cut a little.
To ensure efficient airflow and no reverse thrust the entire structure must be sealed. Therefore, using a sealant or plastic remnants that appeared after the deflector was cut, the slots are clogged.
If all actions are completed, the ventilating device is installed in the highway area, after which it is 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 circuit to the conductor where the current appears when the ignition is activated. This option is more convenient. It is allowed to connect the device to the heating unit control cable.

damper retrofit

Refinement of the VAZ 2107 stove, which consists in upgrading the lower damper of the system, is the easiest option to implement. If all actions are performed correctly, then the device will not randomly open or close when the car is driving over bumps. This will ensure efficient and equal blowing of both windows.

The upgrade procedure is as follows:

It is necessary to visually assess the body of the heating unit. In its corner, there is a hole of the required diameter for performing work. If it is not there, then it is drilled. For this, a drill with a diameter of 6 mm is used.
A bolt is inserted into the hole made from the inside. The shutter itself closes.
After that, using the same drill, a hole is drilled directly into the handle of the device. It is necessary to drill so that the hole is located at the level of the bolt installed earlier. In this case, the length of the screw must be such that by lifting the shutter, the element can freely enter the hole made.
If everything is done correctly, then the bolt is tightened with a nut. It is recommended to use a black part, then it will be difficult to see.

About the features of traction refinement air damper said the user Nail Poroshin.

Rear Seat Heating Upgrade

To upgrade the heating system rear seats you will need to install an additional "snail", which can be used from the VAZ 2108:

First you need to make a body to fix the "snail". To accomplish this task, you need to cut the plexiglass.
Using regular hair dryer, it is necessary to carefully make bends on the glass so that it turns out as shown in the photo.
Then, with the help of a hair dryer, you must carefully change the shape of the body. It is necessary to act carefully, otherwise the "snail" may not be in the landing site.
When performing a task, you can remove the device stub with a utility knife. This will reduce the dimensions of the part by about 3 cm.
Then the side walls of the structure are made. To do this, you can use duralumin or other similar material. The wall thickness should be 1.5 mm.
The next step is to remove all the cracks. For this, the joints of the device must be sealed with adhesive-sealant or other means.
Then you need to work with the channels through which the air will flow to the holes of the blowers. These elements are recommended to be collapsible. For manufacturing, it is desirable to use a similar material.
In order to reduce the amount of resistance and remove turbulence, the turns of the air channels must be smooth. They can be made from duralumin.
At the next stage, it is necessary to build slots that will be used to heat the legs. We are talking about the front airflow - for the driver and passenger. Slots must be equipped with dampers. You can optionally install a variable resistor device that will be used to control the speed of the electric motor. This element can be put instead of a resistor designed to change the brightness of the backlight.
The main stage in this modernization is the construction of an effective heating system for the legs of passengers sitting in the back. To do this, it is necessary to additionally install several branch pipes of greater length. The radiator device is quite powerful and its power will be enough to supply the air flow back. All connecting points of lines and blowers are sealed to prevent leakage of warm air flow.

Improving the efficiency of blowing the legs

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

The upgrade procedure is as follows:

The first stage is carried out in the car. It is necessary to dismantle the lower part of the heating unit. A standard ventilation device is installed here.
The fan is being removed. It is no longer needed, it can be disposed of.
Then the plastic comb is cut, which supplies airflow to the floor of the machine. On the "eight" units, the fan motor is larger in size.
The ventilating device equipped with two blades is being dismantled. Instead, a node with five elements will be used. Before installing a new device, it is necessary to diagnose the quality of its work. To do this, the node is connected and tested.
If the device works correctly, then it is installed instead of the old one. After installation, the assembly must be properly fixed. This will prevent the negative impact of vibrations during movements and the rapid failure of the device.
In order for the ventilation unit to function more quietly, it is necessary to replace the resistor element. This is due to the fact that the device allows you to overtake a larger volume of air flow and operates more noisily. Therefore, a resistor element is being installed, which can be used from the VAZ 2108.
The buttons, as well as the regulatory components of the ventilation device, must be replaced with new ones. It is allowed to use parts from the VAZ 2108. The regular key from the "seven" is suitable in size and fastening. But it quickly fails as a result of a large difference in the magnitude of the current. At this stage, the modernization procedure can be considered completed.

Refinement of the thermostat

Thermostat from a Chevrolet Niva car

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

First, the refrigerant from the cooling system is drained. The car engine warms up, a container is placed under it and the liquid is drained.
opens engine compartment, the thermostat is dismantled with the lines connected to it. It is necessary to disconnect the outlet pipe located below, it goes from the radiator device to the element to be replaced. The bypass line is disconnected, it is installed on top, as well as the hose going from the thermostat to the pump. The condition of these pipes is assessed. If they are worn out or damaged, then new ones must be prepared.
The refrigerant outlet pipe and the copper pipe are disconnected. The last element is unscrewed from the pump, for this you need to unscrew the two nuts and dismantle the flange from the studs.
The lower removed line is taken and the middle part is cut out of it. The length of the segment should be about 7-9 cm.
A new thermostatic device is being installed. Its connection is made using a pipe with a water pump. The hose must be bent a little in advance.
Then a thick pipe from the VAZ 2108 is taken and adjusted to the place where the lower regular hose was installed. From the two ends of the element, you need to cut off the same parts and connect it to a new device. In principle, the installation of a standard line is also allowed, but this option is simpler.
The upper hose is being installed, we are talking about a standard pipe.
Instead of the dismantled line, a plug is made; it went from the heating unit to the water pump. To do this, you need a copper tube, a connecting flange is soldered from it. A sealing element is made of rubber, then the surface of the pipe is treated with a sealant. The design is screwed back to the water pump.
The next step is to connect the refrigerant outlet pipe from the heating device with an input on the thermostat. To complete the task, a dismantled copper hose is taken, the excess part is removed, then it bends a little.
A bracket is being made that will be used to fix the nozzle to the outlet manifold device.
The outlet line from the heating unit with the hose, which was previously disconnected, is connected. The output from the stove remains the same, and the input will go not to the pump, but to the thermostat.
The end of the line with the corresponding inlet is connected to the thermostatic device; this will require a shorter and curved pipe. It is used to remove refrigerant from the cylinder head to the heating unit. This element must be adjusted in advance in length. Difficulties may arise when using an aluminum thermostat, since the walls of such devices are thicker. This means that the line must be used with a large diameter.
The thin pipe of the heating system of the inlet manifold device is fixed to the thinnest outlet of the thermostat. You must first disconnect the end leading to the lower line from the heating device to the water pump. The pipe is measured, if necessary, the excess part is sawn off. The junction is treated with a sealant. To prevent leaks, the amount of adhesive must be large.
Then the junction of the nozzles and the thermostat is pulled together with clamps. The heating system is filled with refrigerant. The engine is being started. If the system has formed airlock, then it must be removed.

Valery Imenov spoke in detail about installing a thermostat from a Lada Granta car on classic VAZ models.

Installing an additional pump

Mounting another pump on the heating unit will provide better interior heating in the car. Usually this device is installed next to the battery and pipes in the engine compartment. When performing the task, it is necessary to dismantle one line coming from the cylinder block. This pipe is connected to an additional pump. From the cylinder block, the line should go to the front of the water pump, and the outlet pipe will be connected to the heating system.

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

To power the pump, do the following:

The first connector with conductors is being dismantled. Several electrical circuits are connected to it. Conductor gray color designed to activate the heated rear window, this is the main cable.
This wire connects the power cable from the water pump. The cable itself is led into the engine compartment through a technological hole.
For a better fixation of the conductor contact element soldering is recommended.
Once the shoe assembly is complete, the optional water pump is ready for testing and operation.

About installation and connection features additional pump on classic models VAZ told the channel "Autoheating".

If necessary, the connection of the water device can be made by another method:

To complete the task, you will need a block from injectors or a knock controller. This item is purchased at any auto shop.
Two conductors are soldered to the ends of the block, and then the cables are installed in the corrugation and wrapped with electrical tape.
Then the electrical circuit is output to connect the ground, you can use any conductor available on the bracket near the installation site.
The harness itself is installed upwards, the resistor elements of the heating unit are connected to the connector where the positive contact was taken. This will automatically activate the water pump, which draws about 1.5 amps during operation. This connection method allows you not to use additional relays and connect with the positive output in the connector directly.

Many car owners install not "VAZ", but "foreign" pumps on cars. You can use the device model 0392020034 from the manufacturer BOSCH. The performance of such a pump is 750 liters per hour, but additional clamps must be purchased, as well as about 10 meters of corrugation. Before performing the task, be sure to drain the refrigerant from the system.

The complexity of installing a branded water pump lies in the fact that the diameters of the hose and fittings of the device do not match. The first is 1.6 cm, and on the pump it is 2 cm. Therefore, it is recommended to use more elastic hoses. This will allow you to pull the line onto the fitting. For better passing the element can be treated with motor fluid.

The heating and ventilation system in the car is used to create a comfortable microclimate in the car. Ventilation and heating of the VAZ 2107 interior is provided by air taken from outside. It enters the system itself through the openings of the hood in the form of a lattice.

In the air intake box, which is located at the rear of the motor compartment and is isolated from it by a rubber seal, air is separated from rainwater. The latter flows out, and the air passes into the heater. The hole in it is closed with an air inlet cover. When the car is moving, part of the air is diverted through the air duct from the box to the central air diffusers located on.

The device of the stove in the VAZ-2107

The heater itself is located in the VAZ 2107 cabin and is attached to the partition of the engine compartment with 4 studs. The junction with the car body is sealed with a rubber seal. The oven consists of:

fan shroud,
radiator casing having an air intake cover,
fan casing with air distributor cover.

The air passing through the heater is heated, if necessary, liquid radiator, which is located in the casing. read how to replace the heater valve.

It has branch pipes: inlet and outlet. They are brought to the engine compartment and connected to the cooling system. car engine. rubber seal the opening of their output is sealed. It is secured with two screws. The heater valve is built into the inlet pipe. It regulates the flow of coolant. And it can be controlled by flexible traction from the lever in the control unit of the ventilation system. The latter is located on the instrument panel.

A VAZ 2107 stove fan is installed under the radiator. Its electric motor with an impeller is mounted on 2 elastic cushions, which are placed in a guide casing. An additional resistor is built into the motor power circuit. It provides a two-speed fan rotation mode, which can be turned on by a switch on the instrument panel with three positions of operation.

Air ducts extending from the stove fan casing direct air not only to the deflectors blowing the side windows, but also to the air duct blowing the windshield.

You can control the air flow by closing and opening the covers and dampers of the heater. The air intake cover itself and the air duct dampers are controlled by rods from the levers on the control unit. But the air distribution cover of the casing is controlled by a lever that is located on it.
The diagram of the device of the stove is shown in photo 1.

Among the main malfunctions of the VAZ 2107 heating system:

leakage of the radiator, faucet, branch pipes or connections between them;
malfunction of the switch of the available operating modes of the electric fan,
damage to the wires of the device or oxidation of their connections;
breakdown of the electric fan.

With more complex faults may be required.

Modernization of the heater VAZ 2107

All motorists know that the VAZ 2107 stove does not heat well, and it works noisily. Therefore, it is often upgraded. Lots of tips for improvement this device with photos and videos are available on the Internet. Most car owners tried to improve the operation of the stove with their own hands. However, this did not produce the desired effect. For example, you can do it yourself:

seal the joints of air ducts with nozzles,
redistribute air currents.

But the temperature in the cabin as a whole will remain at the same level. But in order to become warm and comfortable in the cabin, an increase in the amount of heat supplied with the help of a radiator is required. The whole problem lies in the factory stove fan, which is too small and does not create the desired airflow. As a result, the fan needs to be replaced.

If we compare the fans of two car models, we can see that the motor of the VAZ 2107 stove, when rotating at a frequency of 3000 rpm, consumes a current of about 4.5 A. The fan motor on the VAZ 2108 consumes 14 A at 4100 rpm. next:

The lower part of the stove is removed in the cabin - a casing on which a conventional fan is fixed on top.
The standard electric fan is completely removable and will no longer be needed.
One of the aerodynamic ridges is carefully cut off, which supplies air to the legs of the driver and passenger, since the motor from the 2108 model is much longer.
The impeller is removed, and all functions are given to a standard five-bladed fan.
The hole in the impeller slightly increases in diameter, it is carefully inserted into it new shaft. It is important to ensure that new design became secure in the new place.
Before installing a new fan, you need to connect it directly and check its operation.
The built-in resistor is replaced, the main task of which is to ensure relatively quiet operation of the fan. New fan due a large number distilled air creates loud noise. The best option replacements - a resistor installed on a VAZ 2108 car.
The fan switch is replaced with a model from the same car as the whole structure. Reason is during long work the stove is supplied with a completely different current, as a result of which after a while the standard power button will simply melt.

The noise from the updated device will be a little more than the factory one, but this drawback in the cold winter time is almost imperceptible after the heater has been finalized.

Operation and maintenance of the VAZ 2107 stove radiator

During the autumn-summer period of operation of the car, scale accumulates inside the heater radiator. As a result, the efficiency of the system is reduced. But this problem can be fixed. It is enough to disassemble the stove and clean it. You can do this simple repair yourself.
For this you will need:

2 new worm clamps;
2 rubber new gaskets;
wrenches;
coolant;
vessel for collecting used coolant.

The order of work is as follows:

The engine must be turned off and allowed to cool.
A rag or cloth is placed under all nozzles.
The clamps of the outlet and inlet coolant hoses in the engine compartment are loosened.
The hoses are removed from the nozzles and the faucet, you must first substitute a container under them.
With a socket wrench for 7, the screws of the seal fasteners are unscrewed, which subsequently must be removed.
Disconnect the drive rod of the stove tap and the fan casing.
Radiator pipes are removed from the hole in the bulkhead of the engine compartment.
With a 10 spanner wrench, the bolts of the radiator outlet pipe are unscrewed, after which the pipe itself is removed.
Replaced with a new rubber gasket sealing the flange joint. 11. After removing the tap, clean the pipes, hoses and the tap itself.
Flushing the radiator can be done in the way shown in the video.

12. All removed gaskets and clamps are replaced with new ones.

Assemble the heating system in reverse order. Heater valve before filling up to required level new coolant is transferred to the right extreme position. After topping up the liquid, check the tightness of all connections. If a leak is found, tighten the clamps.

Trying to refine the VAZ 2107 heater without the necessary knowledge base, it is impossible to achieve an effective result. Many motorists are trying to redistribute the air flows or, for example, seal the joints of the air ducts, but the result remains the same - the temperature in the cabin does not change. To feel comfortable, you need to act drastically and increase the supply of hot air through the stove radiator.

But there is a small nuance: too small a fan is installed on the VAZ 2107, therefore, it is problematic to create an impressive air flow, which means that you need to install a fan more power. The best option when finalizing the heater, use a fan from the VAZ 2108.

Let's get to work and start with careful preparation. We remove the lower part of the stove from the passenger compartment of the VAZ 2107 car. We permanently remove the standard electric fan. In order for the motor from the eighth model to fit snugly on the casing, it is necessary to cut off one of the aerodynamic ridges (which directs air to the legs).

We turn to the finalization of the impeller. Functions given element will have to be assigned to a standard five-blade fan. We increase the hole in the impeller and put the shaft from the new electric motor into it. Pay attention to the fact that the whole structure is in place.

Before you modify the heater, do not forget to directly supply power to the motor and check its performance. Final stage- the solution to the problem with the resistor. It is necessary to ensure the quietest operation of the stove, because the improved heater supplies too much air, resulting in a hum. The problem is solved simply: we change the standard resistor to an analog from the eight. It is also worth installing from the VAZ 2108 and an electric fan switch.

In winter, you will immediately feel the benefit of the improved VAZ 2107 stove, simple revision and what is the result.
