Viburnum heater diagram of the movement of air through the ducts. Cold air blowing stove on Lada viburnum

The heater device Lada Kalina allows you to most effectively use the functions of the car. Lada Kalina belongs to the family of domestic small cars. At the AvtoVAZ plant, production began in 2004. For the first time, the engine was equipped with electronically controlled fuel injection. The car is equipped with anti-lock brakes, airbags, electric power steering. On the new Lada Kalina model, front door windows appeared, an improved heating device was developed that allows heating the front seats of the driver and passenger.

The Lada Kalina heating system makes it possible to maintain a comfortable temperature regime of the air in the cabin.

What is the heater

The principle of operation of the Lada Kalina heater is simple. Scheme of the heating system supply and exhaust.

The heater consists of:

• ventilation and heating filter with a filter element;
• air duct;
• radiators, air distributor;
• electric fan.

The interior is heated by a heating system, which is installed under the dashboard. At the time of operation of the car engine, heated liquid passes from the cooling device through the radiator, warm air flow is distributed throughout the cabin. The amount of incoming heat is regulated by the damper control knobs. It is possible to direct heat by turning the guide blades of the ventilation grilles located on the dashboard.

The air flow enters the cabin through the intake device, which is located in front of the windshield on the hood of the car. The air streams pass through the cleaning filters and are distributed throughout the car with the help of a fan.

The ventilation device operates in four speed modes, the rotation speed is regulated by the operation of resistors. The fan speed is set using the ventilation and heating device control unit located on the dashboard.

Diagnostics of the heating system Lada Kalina

Before diagnosing a heating system, it is necessary to carefully consider the device diagram. The check must only be carried out with the engine running:

1. Turn the knob of the air temperature regulator to the extreme left position.
2. To check the fan speed, it is necessary to switch the control starting from the first speed. In the absence of a malfunction, the airflow strength should increase.
3. When checking the operation of the dampers, it is necessary to turn the heat regulator to the extreme left position, put the fan control knob on the fourth speed.
4. Working condition of dampers. Turn the damper control knob to observe the change in airflow direction.
5. Checking the thrust of the heater dampers is carried out on an engine warmed up to operating temperature. Make sure there is no malfunction. Turn the heat regulator to the extreme right position. Hot air will come out of the duct.
6. Checking the temperature sensor, which is located in the lighting lamp under the ceiling panel. Its performance is determined by the temperature of the air that enters the car interior.

Heater malfunctions

In the event of a heating malfunction, you must first check for the presence of coolant, fuse, additional resistor, switch, power circuit.

If the air flow is low, the air filter should be replaced. When the air temperature does not change when the engine is warmed up to operating condition, it is necessary to check the unit that controls the operation of the ventilation and heater.

When the temperature sensor goes out of operation, only hot or cold air will come out of the nozzles located on the control panel.

Depressurization of cooling is a common cause of failure of the heating system. In this case, the coolant comes out gradually. You can detect a malfunction by the characteristic smell that appears in the cabin.

Every car owner knows how important the operation of the heating system is, especially in cold winter conditions. If the stove fails, this will at least bring considerable inconvenience to the driver and passengers, so the performance of this unit must be at the highest level. You can learn more about how the stove is replaced on Kalina and in what cases it is required from this material.

Possible malfunctions of the heater and ways to eliminate them

If the stove blows very weakly or in the current mode it basically refuses to blow air, then there can be several malfunctions, as well as troubleshooting methods:

1. The heating system hoses are worn out. As a rule, if the stove does not heat up or not, this may be due to wear on the nozzles. To solve this problem, it is necessary to make a thorough diagnosis of each of the nozzles. Through cracks, as well as other damage to them, coolant can escape.
2. Out of order . If the stove control valve is broken, this can be indicated by traces of consumable leakage in the vehicle interior.
3. There were malfunctions in the operation of the control unit. If the problem lies in the unit, then first of all it is necessary to check the quality of its connection to the on-board network. If it is connected correctly, then most likely the problem lies precisely in it. It is better to entrust the repair of the block to specialists.
4. Wiring faults. Perhaps the unit does not turn on the heating system due to the lack of contact with the on-board network. In this case, the problem is solved by stretching the chain to find the broken section.
5. The auxiliary resistor has broken. This device is used to control the heater fan, so if the stove on Kalina does not heat up, you also need to check the performance of this element. If it doesn't work, then it will need to be changed.
6. The Kalina stove regulator, located in the passenger compartment, does not work. If the heater blows only hot, and when it is switched from hot to cold air, it does not react in any way, then most likely the regulator installed on the center console has failed.
7. The radiator of the heating unit broke. This problem is considered one of the most common on domestic cars, it is especially relevant for Kalina. You can try to repair this device or change it yourself. We will tell you more about how to shoot and how to replace the device below (the author is the Interesting video channel).

Instructions for replacing the stove

Before removing all the necessary parts, cables and other components from Kalina, prepare a new radiator, pipes and clamps. Branch pipes will be required in case the old ones are worn out or they have never changed over the years of work. As practice shows, hoses are most subject to wear during temperature changes, so in any case they need to be changed from time to time.

Instructions on how to change the radiator are presented below:

1. We begin the replacement procedure in the engine compartment. First you need to substitute a container under the drain hole and drain all consumables from the radiator. If you notice that the coolant is already old and has worked out its service life, which can be understood by its color and deposits, then it is also better to change the antifreeze.
2. You need to provide the most convenient access to all pipes and hoses of the radiator assembly in the engine compartment. To do this, dismantle the air filter housing of the power unit, the battery, as well as its platform. Next, you need to disconnect all lines from the radiator device in the engine compartment. Having done this, using a wrench, you can unscrew the nut that fixes the metal casing to the motor shield. This nut is located next to the pipes that go into the interior of Kalina.
3. Next, we move to the interior of the car. You need to dismantle the gas pedal, to do this, unscrew the three nuts. As for the brake pedal, it will not be possible to dismantle it, so just take it to the side as far as possible.
4. Now you have to cut the steel casing as shown in the photo, and then cut the tubes of the radiator assembly. Having done this, you can dismantle the device from the pedal side, but this will also require unscrewing the bolts that fix it.
5. Before installing a new radiator device, it will be necessary to carefully sand its tubes with sandpaper. Please note that they should be as even as possible. After all surfaces are ready, a line with an expanded end is put on the upper tube, and a narrower end on the lower tube. The remaining outputs must be connected in the engine compartment instead of the old ones. Also note that from the side of the Kalina cabin, it is advisable to treat the exit point of the highways to the engine compartment with soundproofing material.

Issue price

The range of radiator units for Kalin is not very large. On average, the prices for radiators are the same.

The air stove Lada Kalina is considered one of the best in terms of heat in the VAZ family, but far from the most reliable in operation. Problems begin almost in a car dealership, as many motorists talk about. But most of the problems are completely solvable, and often even without the involvement of car service specialists.

Common faults

The stove itself on Kalina is well conceived, but due to the poor quality of the manufacturing of elements and parts, various troubles constantly happen to it. Even the latest models with climate control have different “diseases”. The list of the most common faults is as follows:

• the heater core is leaking;
• jamming or not fully opening the damper of the stove;
• failure of the fan or control unit;
• breakdown of the motor reducer;
• the temperature sensor or the heater resistor has become unusable;
• the cabin filter is clogged.

To find out where this or that element of the heating system is located, it is worth looking into the instruction manual, there is always a corresponding diagram there.

The design of the Kalina stove without climate control is such that the air sucked in by the fan passes through the air filter and enters the heater radiator. There it is heated and fed to different areas of the cabin through adjustable grilles and openings. The dampers are controlled and the fan speeds are switched manually. Such a heating system is more reliable, since it does not have any electronics.

On the Lada Kalina with climate control, the dampers are controlled by a gearmotor at the command of the electronic unit. The latter receives signals from a temperature sensor located in the passenger compartment and reacts accordingly to changes in the microclimate. The controller interacts with both the heater and the air conditioner.

Diagnosing and Troubleshooting

The easiest way to solve the issue concerns the cabin filter. For the first time, a thorough purge of the element will be enough, but then it is better to replace it. The real trouble is a radiator leak or a fan failure, and an expensive replacement of the unit cannot be avoided. An equally high price will have to be paid for a new control unit.

It will cost a little less to install a new temperature sensor, a gearmotor or a Kalina heater resistor. Moreover, the malfunction still needs to be correctly diagnosed, which can be quite difficult. A burnt resistor is easily detected - the fan only runs at maximum speed. It is more difficult to check the sensor hidden in the lighting dome. Symptom - Hot or cold air flows from one or more grids, regardless of the position of the regulator knob.

It is more difficult to find out how well the mechanical controller of the stove is functioning. To do this, you need to get to it by disassembling part of the front panel. In the same way, the correct operation of the air dampers is clarified.

To diagnose problems, it is better to start with the most accessible elements, and only then proceed to disassembly.

How to change the radiator

The operation is very laborious, for which a car service will charge you a round sum. But there is another, slightly barbaric, but fast and widely practiced way. The scheme of work is as follows:

1. Drain the antifreeze, disconnect and remove the battery, then disconnect the hoses from the stove pipes.
2. Unscrew the nut located near the fittings in the engine compartment. She holds a steel plate that will interfere with the dismantling of the heater.
3. Remove the gas pedal and pull out the steel axle of the brake pedal. Unscrew the decorative, and behind it the plastic panel covering the stove radiator.
4. To remove it, cut an opening in the plastic frame to allow the radiator to be pulled out towards the driver.
5. Install new element and assemble in reverse order. The cut opening can be sealed with plastic and decorated in any suitable way.

When performing an operation, it is worth moving the controller located directly under the stove to another location. Antifreeze dripping from it can damage sensitive electronics. Also, with the radiator removed, it is easy to change a faulty heater tap or gearmotor, because they will be accessible. The gearbox is a single unit with a damper position sensor and also changes entirely.

Fan Replacement

It is most convenient to get to the unit from the side of the passenger seat, which will have to be dismantled so that you do not have to do acrobatics inside the cabin. The runners of the chair are held by 4 nuts measuring 13 mm, it will not be difficult to unscrew them. Further work on replacing the fan is carried out in the following sequence:

1. Remove the cabin filter, remove dirt and dust from the opening.
2. Unscrew 4 self-tapping screws located on the back wall of the glove box, and one more - under the right heater grille.
3. Remove the plastic trim from the rack and unscrew the 2 screws that secure the panel and the blower unit.
4. Dismantle the blower assembly, lift the plastic panel and loosen the 2 fan fastening nuts located under it.
5. Move the torpedo as far back as possible and fix it. The turbine must be removed from below, from a prone position.

You should not rush to change the fan when it only works at speed 1 and the stove switch is at maximum. This is a sure sign that the resistor located below the glove box has failed. The part is a small green plastic panel with a connector for connection. Replacing the stove resistor is carried out without any disassembly, you just need to disconnect the connector and unscrew the 2 screws that attach it to the body.

Basically, troubleshooting the Kalina stove is a simple, but very time-consuming job. To change a small part, you need to spend time disassembling to get to it.

"I will never buy Kalina for myself just because of this procedure" (c) Igor09, site E1.ru

three screws for fastening the radiator and three wrench nuts for 10 fastening the gas pedal

To all owners of Kalin! It is better to immediately pull the ECU out of its regular place and place it anywhere, as far as the wires allow, but not under the stove body

Two bolts secure the pad, it is Velcro, it’s safe to tear it off and you will be pleasantly surprised by the number of nuts and screws under it :-)

These screws do not need to be loosened.

It's all to tear or tear, dump a slide into a corner

To unscrew the tunnel screw, you must first loosen one handbrake fastening bolt and unscrew one completely

This bolt of fastening the body of the stove does not need to be unscrewed until you remove the torpedo panel

Then it will be much more accessible.

We also unscrew this bar after removing the torpedo

We keep spinning

Removing the dash panel

Now you can move the stove body and remove the radiator

We fold the bolts and screws carefully so that later we don’t forget which one was unscrewed from where and where to screw it later during assembly

We did NOT have enough three screws and two nuts :-) I had to get it from stocks

By the way, in order to deploy the stove body, you must first get the air duct from the motor to the stove body

Before that, halving the motor housing

robinzon66, site E1.ru

I am adding pictures of a more correct, according to the manual, way to replace the stove radiator at Kalina.

We take out the saddles, unscrew the EUR with the relay shaft from the panel and move the entire panel

One way to remove the heater core involves removing both front seats, tunnel, electric power steering column and pulling out the entire front panel.

The second method, described by me, involves dismantling the panel lining and pulling out the stove body.

Both methods are quite complicated, expensive and entail subsequent probable malfunctions of the wiring and some nodes. a lot of things need to be turned off and unscrewed.

The third method, which I propose for discussion, is distinguished by the fact that a minimum of nodes and connectors is removed, it takes many times less time, but it requires some refinement of the radiator and pipes. Well, of course, if less time is spent on repairs, then its price is also less.

We have Kalina with air conditioning and a leaking stove radiator. By the way, the advantage of this method is that I can’t even imagine what it will take to remove the entire panel if there are still tubes and an air conditioner evaporator (!) We DO NOT remove the panel here.

Saw off both tubes with a hacksaw. The length should be chosen according to the bead-thickening of the thick tube.

We heat the sawn ends with a lighter.

And resting on something strong and cold, we make new flanges so that the stove pipe does not slip when there is pressure in the cooling system

I won’t describe in detail the unscrewing and dismantling of the electric power steering column, the gas pedal and the brake and clutch pedal assembly, it’s not so difficult there, but still be extremely careful

And now we have cleared the space for violence

The next step is to saw off the pipes of the old radiator, unscrew the covering plastic and metal plates and the radiator can be freely removed

View of the opening for pipes from the engine compartment

In advance, you need to buy two pipes from the thermostat to the stove tap from nine. One fits perfectly in length, and the second must be shortened in place, BUT taking into account the fact that you have already sawed off part of the radiator pipes.

We insert our new castrated radiator, put on the pipes and tighten with clamps

We close with caps, plates, put the noise-thermal seal in place

The heating system in the cabin of the budget model Lada Kalina can significantly increase comfort for the driver and his passengers. It maintains the required temperature inside the car. Along with useful options such as:

• "ABS";
• airbag;
• electric power steering;
• electric front windows;
• front seat heating function,

The arrangement of the interior stove allows the manufacturer to achieve a fairly acceptable level of equipment, which is very worthy for a small class model Lada Kalina and makes it competitive among its rivals in this segment.

The composition of the heating system

The principle of operation of the heater in Lada Kalina is very simple. It is built on a supply and exhaust scheme. The heater circuit contains:

• cabin air filter;
• air ducts;
• heater radiator;
• electric fan;
• air flow control module and fan operation modes.

The interior stove device looks exactly like this, but is located behind the dashboard and only the system controls are present on its front surface in the Lada Kalina cabin. A running engine generates heat, which is removed from it by the cooling system. This circuit includes a heating radiator. The circulating fluid heats the honeycombs, from which the warm flow is directed into the passenger compartment by means of a fan. Adjustment of the required temperature, strength and direction of the air jet is carried out by means of the handles and dampers present in the cabin. Sometimes damper adjustment is required.

The air taken from the external environment initially passes through the intake element located on the hood at the bottom line of the Lada Kalina windshield. Further, the air rushes to the filtering component and is supplied through the fan into the cabin space.

The fan is capable of operating in 4 different speed modes. Adjustment is carried out by means of the corresponding knob on the tidy, and the switching itself is possible due to the presence of a resistor block in the control module.

How to diagnose the heating system in Kalina?

Before a diagnostic event, you will need to carefully study the diagram. Checking should only be done while the engine is running.

1. The temperature regulator located on the control unit in the passenger compartment is set in the leftmost position. We activate the fan and observe the hot air entering the cabin through the deflectors. By gradually shifting the handle to the right until it stops, we reach the exit of a cold air stream.
2. The speed test should be started by setting the appropriate knob to the minimum speed position. If the fan and its control module are in good order, then the force of the air jet should increase as the handle is moved to subsequent positions (and so on up to the 4th speed mode, corresponding to the maximum speed).
3. Checking shutters. Here, the temperature level control is shifted to the maximum to the left position. We move the fan speed switch to the position corresponding to the 4th speed. The check itself is reduced to the smooth movement of the damper regulator between the extreme positions. This should be done in order to feel the correction of the flow direction. By transferring the temperature mode regulator to various positions, we observe a change in the degree of heating of the incoming air.

List of faults in the heating circuit

If the owner of LADA Kalina suspects the presence of any deviations from the normal functioning of the heating system, then the following diagnostic procedures will be required.

1. The first step is to make sure that there is a sufficient amount of antifreeze in the cooling circuit.
2. Next, check the integrity of the fuse.
3. We make sure that the fan speed control is working properly.
4. A weak air flow penetrating through the deflectors hints at the need to check the condition of the filter component.
5. If a warm stream is not supplied to the cabin on a warm engine, then there may be air pockets in the cooling system or jammed dampers in the air ducts.
6. A faulty temperature sensor will cause only hot or vice versa cold flow to enter the cabin.
7. Among the common causes is the depressurization of the LADA Kalina cooling system. Sometimes the reason for this may be the loss of tightness by the heater radiator itself. At the same time, antifreeze will enter the salon, posing as a specific smell and a wet decorative floor covering. In order to detect a leak in a timely manner, it is required to control the level in the expansion tank with frequent intervals.

Summing up

The heating system is simple. Timely diagnostics can save the owner of LADA Kalina from unforeseen breakdowns, and the heater circuit will also help in this. Keep track of the level of antifreeze, change it according to the regulations, and the radiator of the system will serve its scheduled resource, delighting you with warmth and comfort in the cabin.

If you have a stove blowing cold air on Lada Kalina, but at the same time all the equipment is in good order, there are no air jams and all sensors are normal, then you should think about the fact that, most likely, the problem lies in the dampers of the car's heating system. It is quite difficult to identify this problem, usually the elimination method comes to it when all other elements of the heater have already been checked.
As part of this article, we will talk about what usually precedes the identification of problems with the heater dampers, as well as share information on how to fix such an unpleasant situation.

It is worth noting that there is a publication on our website that describes in detail a method that will allow even a complete beginner to cope with the task.

Signs of a malfunction of the dampers of the heating system Lada Kalina

Most owners of Lada Kalina cars note that even at a temperature of -25 degrees Celsius outside, it is enough to turn on the stove at first speed and it becomes warm in the cabin. At the same time, after a certain period of time, the intensity of heating begins to fall, and it becomes insufficient to start the heater at the first speed, you have to switch to the second, and sometimes even further.

The thing is that Kalina, like a number of other VAZ-made cars, has a native “disease” - even in the most extreme position of the temperature control knob (as hot as possible), the damper does not open completely. As a result, with minimal wear of the heater elements, the heating of the passenger compartment begins to decrease. To make sure that your car has such a problem, just look at the stove body from the driver's seat. You will be able to see the lever of this damper, which works with an incomplete amplitude, and the cable that fits it.

Fortunately, there is a method to fix this problem, but you will need to make some adjustments yourself, which we will cover in the following sections of this article, but first, we will explain how to make sure that this is the problem in your particular case.

We check the presence of a “disease” of the dampers on the Lada Kalina

So, your stove does not heat well, you suspect that the matter is in the dampers, but how can you determine this for sure? To begin with, you must bring the temperature sensor of the multimeter to the central deflector and measure the temperature at the first speed of the heating system. On a cold car, you should get a value of at least 46 degrees Celsius.

The next step, you must move the cabin air speed lever to the extreme right position. As a result, the temperature must rise. This will happen in any case, whether you have a problem with the shutters or you don’t have it, but if there is a problem, the multimeter readings will increase slightly - no more than 10 degrees, and maybe even lower.

What will be required to restore the normal operation of the stove?

If you have a situation with a slight increase in temperature when moving the lever from the first speed position to the maximum speed position, you will have to work on upgrading the damper system. For this you need quite a bit:
– spring of small length and medium stiffness
- pliers, which will allow, if necessary, to modify the length of the spring to the size you need

The procedure for upgrading the heater dampers Lada Kalina

The upgrade procedure is quite simple, but requires accuracy and concentration. You need to hook one end of the spring to the lever with which the dampers move, and the other to the protrusion that is on the body. That's all.
As a result of the refinement described above, the spring will begin to press the damper lever much more strongly, as a result, the amplitude of damper movement will increase to a maximum, and the quality of the car’s heating system will increase significantly.

What to Expect After a Damper System Upgrade Procedure

After you have finalized the damper system, you can forget about problems with them for a sufficiently long period, since their service life is very long. If after that, the stove stopped working for you again, then you can no longer pay attention to the dampers and look for a problem in completely different elements of the car’s heating system: tap, radiator, engine cooling system, and so on.
