Depending on the configuration, the layout of the Lada Kalina stove may vary. In one case, the design of the ventilation and heating system is simple and reliable, in the other, temperature control in the car interior is controlled by automation and electronics. Let's look at the operating principle of the Lada Kalina heater in different modifications.

Elements of the heating system LADA Kalina

The ventilation and heating system of the car interior is a supply and exhaust system, while the temperature of the liquid heated above 90 °C from the engine cooling system is used to heat the interior.

Heater parts: 1 — filter housing for the interior ventilation and heating system; 2 - filter element; 3, 4, 5, 6, 7 — air ducts; 8 — radiator casing and heater air distributor; 9 — heater radiator; 10 — casing of the electric heater fan; 11 — electric heater fan

Summary

The Lada Kalina car is available with a ventilation and heating unit or with an air conditioning unit. For the first option, it is impossible to provide a cabin climate whose temperature will be lower than the ambient temperature.

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

Heater fan (stove)

When the door windows are closed, air is supplied to the cabin by an electric fan. The intensity of the air supply is regulated by the rotation speed of the electric fan impeller. The fan electric motor has four speed modes (lower speeds are provided by an additional resistor with two windings).

Cabin filter

Air intake is carried out through an air intake installed under the windshield frame. To clean the air entering the cabin, a filter element made of non-woven synthetic material is installed at the heater air intake. The exhaust is carried out due to the vacuum that occurs near the rear of the body when the car is moving.

Heater radiator (stove)

When the engine is running, heated fluid from the cooling system circulates through the heater core, heating the air passing through it. The amount of air passing through and around the radiator is set by the central heater damper, depending on the position of the temperature control knob installed on the instrument panel.

The air distribution throughout the cabin can be adjusted by rotating the control knob for the air distribution flaps, as well as by turning the flaps and guide blades of the instrument panel ventilation grilles.

How to change a radiator

The operation is very labor-intensive, for which the car service center will charge you a hefty sum. But there is another, slightly barbaric, but fast and widely practiced method. The work flow diagram is as follows:

Drain the antifreeze, disconnect and remove the battery, and then disconnect the hoses from the heater pipes.
Unscrew the nut located near the fittings in the engine compartment. It holds a steel plate that will interfere with the removal of the heater.
Remove the gas pedal and pull out the steel brake pedal shaft. Unscrew the decorative panel and behind it the plastic panel covering the stove radiator.
To remove it, cut an opening in the plastic frame that allows you to pull the radiator towards the driver.
Install the new element and reassemble in the reverse order. The cut opening can be sealed with plastic and decorated in any suitable way.

When performing the operation, it is worth moving the controller located directly under the stove to another place. Antifreeze dripping from it can damage sensitive electronics. Also, with the radiator removed, it is easy to change a faulty heater valve or gear motor, because access to them will be open. The gearbox is a single unit with a damper position sensor and can also be changed entirely.

Interior ventilation of LADA Kalina

Exhaust deflectors are built into the body panels under the rear bumper. The interior is heated by a heater installed under the instrument panel.

1 - air supply ducts for passengers in the rear seat. 2 - side nozzles for supplying air to the driver and passenger on the front door or on the windows of the front doors. The air flow is controlled by grilles (in the vertical direction and flaps in the horizontal direction. 3 - glass blowing nozzles. 4 - windshield blowing nozzles. 5 - upper air supply nozzle. 6 - central supply nozzles to the cabin.

Control unit for ventilation and heating system LADA Kalina

1 — air temperature regulator;
2 — fan operating mode switch; 3 — air flow distribution regulator; 4- air recirculation control lever; 5 — rear window heating switch The intensity of the air supply into the cabin is regulated by turning the handle of the fan operating mode switch. This turns on one of four fan speeds. By turning the switch handle clockwise, we increase the fan rotation speed.

How the Lada Kalina stove works

The vehicle's heating system must work properly. It is not difficult to achieve uninterrupted operation of the stove if you know the structure of the Lada Kalina stove. The heater creates a comfortable stay in the car interior, creating visibility for the driver. The stove design provides for the use of small-class machine options. The production of Kalin cars began over ten years ago. The following options are included for the base model:

Anti-lock braking system.
Airbags.
Electric power steering.

New Lada Kalina models were developed, which were already equipped with additional options:

Electric door window lifts.
Reliable heater.
Heated seats.
Interior air conditioning device.

Checking ventilation and stove Lada Kalina

Car owners claim that Kalina’s heater heats much better than previous VAZ models. It sometimes breaks down and requires repair. Do a full system diagnostic to ensure it's working properly.

We start the car engine.
Turn the left handle counterclockwise and place it in the blue zone.
We place the fan speed switch in each of the 4 positions one by one. If the fan does not rotate in one of the positions, then check the power supply circuit of the device.
Turn the speed controller to maximum.
Using the right handle (damper control) we check the redirection of air flows. If we notice that there is no change, then the damper drive needs to be repaired.
Warm up the engine to 90°C. Turn the left handle to the extreme position of the red zone.
The air that comes out of the panels should blow warm air.
Return the left stick to the blue zone. Cold air will come out of the nozzles again.
If the temperature of the air flow does not change due to a change in the position of the regulator, then the control of the central damper drive is faulty.

Possible heater malfunctions

Your stove is not working or is not heating well. Look for the cause of the problem. The fan does not work or the heater radiator is leaking - obvious breakdowns that occur at any time.

Stove control unit:

The engine was warmed up, but warm air did not enter the cabin.
The damper drive cables may have come off. The only solution is to remove the console.

Dampers . Partially open or close. The rubber seal has come off in the air duct or foreign objects have gotten into it.

Antifreeze circulation . Start the engine and check the level in the expansion tank, and also check for any disturbances in the normal flow of antifreeze. Possible reasons:

Pump. Cannot be repaired, only replaced.
The cooling system is clogged. Clean or rinse.

Checking the thermostat . Warm up the engine to 75°C. If the upper pipe is cold, then the thermostat does not work correctly and does not allow coolant to move in a large circle. Replace the device.

Air lock . Remove the plug from the vehicle's engine cooling system.

Temperature sensor . Constantly blowing cold or hot air. If cleaning the contacts does not help, then replace the non-working temperature sensor.

Air filter . If the air flow is weak and there is no desired temperature, then replace the filter. Be sure to check the heater resistor, which controls the rotation of the fan and is located under the glove compartment.

Electric fan . The device does not turn on regardless of the selected mode. Check the fuse that controls operation. If the fan is turned on and its operation is accompanied by strange sounds, clean or replace it.

Dampers . It is difficult to determine the breakdown unless you replace the dampers themselves.

The cause of a heater malfunction may be a depressurization of the car's engine cooling system. The types of breakdowns described above cause malfunctions in the operation of the Lada Kalina car's stove. Such breakdowns do not require special knowledge; they are easy to understand and repair.

The main reasons why the stove on Kalina does not work

Of course, the stove on Kalina heats just fine, but, like any mechanism, it tends to wear out. And problems begin: the fan doesn’t spin, or it just doesn’t blow well. Or the stove is blowing cold air.

But don’t be upset, because this can all be fixed. Let's look at the main reasons why the stove does not heat well and blows cold air.

Stove fan

If necessary, it must be replaced, and if possible, repaired. But first check the fan fuse in the mounting block, it may have simply blown.

Coolant level

If necessary, add coolant level

Airing the system

Remove the air and be sure to find where this air may be getting into the system.

Heater radiator

Of course, changing a stove radiator is still a pleasure. And the price for repair work is not low. Well, what to do if it’s cold in the cabin and you know for sure that the reason is in the radiator.
