Most instructions, including the service book for the Lada Kalina car, describe the method for replacing the stove by dismantling the dashboard. This causes a lot of trouble and inconvenience. We will also describe the replacement of the stove without removing the Lada Kalina panel, which is more practical, faster and will allow even a complete beginner to cope with the task.
[i] It is worth noting that in the previous article two ways to replace the fan were described in detail: according to the service manual and the folk method.
Preparatory work
As mentioned above, the method that we will present does not require the dismantling of the dashboard, which means that it will require far fewer tools and materials to implement it. By and large, you will need a ratchet, a set of sockets, a pair of screwdrivers (phillips and flat), and a new stove.
With the latter, we would not recommend rushing, especially if you have little experience in car repair. The thing is that obvious malfunctions of the stove that seem at first glance may turn out to be problems in completely different nodes. Therefore, first remove the old stove and make sure that it is it that is out of order, and after that go to the store to buy a new one.
It is best to buy VAZ stoves, since small savings due to the purchase of stoves from other manufacturers often result in high costs due to the low quality of their products, as well as the almost complete absence of a guarantee.
Algorithm for replacing the stove with Lada Kalina
Replacing the stove without removing the Lada Kalina panel is a real find for the younger generation of car owners. To learn this method, you should carefully read the following step-by-step instructions and be sure to clearly follow everything that is written in it. So let's get started.
Step 1: The first step is to remove the steering wheel column.
Step 2: Next, you should take the pedals. To do this, pull the pedal out about halfway and turn it to the side. Thanks to this manipulation, you will be able to free up the area that will be used to dismantle the radiator. To make this even easier, you can slightly bend the reverse tongue, which serves to create a stop for the sensor.
Step 3: Remove the stopper shaft. Unfortunately, in this case, you will not be able to achieve visual contact, so you will work by touch.
Step 4: Pull out the metal casing, cut it and mount it in its original place.
Step 5: Now you should carefully inspect the radiator. The thing is that it can become clogged, which will require you to clean it with special solutions. In some cases, you may find that it is damaged, requiring you to purchase a replacement.
Step 6: dismantle the valve of the heating system of the car and, as in the case of the radiator, carefully inspect it, clean it, and, if necessary, replace it with a new one.
Step 7: Now you just have to clean the remaining elements of the heating system, carefully inspect them and replace them if necessary. It is important to note one small but very significant detail: radiator hoses are very difficult to put in place, especially if you decide not to change them, therefore, if you have the financial opportunity, then it is better not to save on them. This also applies to tubes, but in their case there is one more important detail - they must have absolutely identical length.
Step 8: Assemble everything in the reverse order and do not forget to add antifreeze to the system, since during the repair process most of it will be lost.
Step 9: Check that your car's stove is working.
Instead of a conclusion
The method described above, although simple and practical, has a number of significant drawbacks compared to the classical technology, which is usually used as an answer to the question of how to change the stove on Kalina. The thing is that with such a partial disassembly of the machine, you will not be able to inspect all the components of the stove well enough, and you will not be able to replace some of them if necessary. Therefore, we recommend resorting to the method of replacing the stove on Lada Kalina without removing the dashboard, only in extreme cases, and when you are sure that either the faucet or the radiator is to blame - two elements that will definitely be in your hands, and you will definitely you can determine the degree of their wear.
I would also like to note one more important nuance regarding the “simple” method of repairing the Lada Kalina stove. Without disassembling the instrument panel, you still cannot avoid contact with it, so proceed very carefully so that its elements do not burst. Also, do not forget about the spilled antifreeze, which must be constantly collected with rags so that it does not spoil the interior of your car.
Cars of the Lada Kalina family are distinguished by an extremely inconvenient location of the heating installation - behind the instrument panel. Therefore, the market value of a seemingly elementary operation is multiplied compared to the “tens” and “priors”.
The leaky heater radiator on Kalina should be replaced immediately - after all, the heat exchanger is located in the cabin above the engine control unit! Obvious symptoms indicating a radiator failure can be:
- antifreeze on the driver's mat;
- adhesive-coated interior panels and glass;
- the smell of antifreeze in the cabin;
- a sharp decrease in the level of coolant in the expansion tank.
Competent replacement of the heater radiator with Lada Kalina according to the "factory" manual
The basic operating manual offers a heater repair technology for implementation, the initial stage of which involves work in the engine compartment:
- antifreeze drain (unscrew the plug first in the front of the cylinder block, then on the right end of the engine cooling radiator);
- removal of the battery from the engine compartment;
- dismantling the engine air filter housing together with the air intake and the L-shaped channel connected to the throttle assembly;
- loosening the clamps and disconnecting the pipes passing through the engine shield, which promote the circulation of antifreeze through the heat exchanger of the stove (made from below the car);
- dismantling the bolted connection that fixes the heating installation relative to the partition of the engine compartment (the nut is located on the engine side near the connection point of the cooling system pipes to the heater radiator);
- removal of the right side of the windshield lining;
- dismantling the cabin filter cover and the filter element itself.
The replacement of a defective heater radiator on Kalina is also preceded by “internal” work:
- removal of seats;
- dismantling of the central floor tunnel;
- removing the plastic casing of the steering column, disconnecting the pads of the steering column switches and the electric power steering;
- removal of the steering column assembly with the EUR (an alternative is to lower the unit to the floor, after removing the steering wheel and unscrewing 4 nuts securing to the body);
- complete dismantling of the dashboard assembly with the heater.
After removing the instrument panel from the seat, free access to the fixing elements of the heating element housing opens and all conditions are created for dismantling the damaged heat exchanger. The process of replacing a defective unit looks like this:
- on the left end of the center console, unscrew 3 screws fixing the heat exchanger casing and the metal bracket for the tube seal;
- dismantle the casing and bracket;
- take out the radiator;
- install a new heat exchanger, fix the casing and bracket.
folk method
The need to remove the dashboard has become an excuse to find an alternative method that excludes this time-consuming operation. Individual repair technology provides for a much smaller set of preparatory measures.
The list of procedures carried out under the hood is almost identical to the one described above, it is not only necessary to dismantle the windshield lining and cabin filter. The range of “internal” work that precedes the replacement of a worn-out heater radiator with one is fundamentally different both in terms of labor intensity and content:
- disconnect the cable from the gas pedal;
- dismantle the throttle foot lever itself;
- remove the sensor for turning on the brake dimensions near the corresponding pedal;
- release the brake pedal from the drive lever by removing the locking clip and the fastening pin to the drive fork;
- dismantle the steering column;
- remove the tunnel lining on the left end of the center console.
The basis of the technology for replacing the heat exchanger of a heating installation is formed by transitions:
- cut off the metal bracket for attaching the heater housing to the engine shield with a grinder (you can save the bracket by sawing off only the pin with a hacksaw blade from the passenger compartment);
- saw off the protruding radiator pipes with a hacksaw (from the side of the gas pedal);
- dismantle the cover for fixing the radiator to the body of the heating installation, having previously unscrewed three screws;
- take out the radiator;
- install a new, already modified heat exchanger;
- connect two hoses, install and tighten the clamps from the cabin side;
- soundproof the window through which the hoses from the engine compartment are fed.
Important! The purchased radiator is subject to modernization: the outlet pipes should be shortened by 2-2.5 cm, cleaned and formed by heating and subsequent deformation of new flanges.
Briefly about the modified factory technology for replacing the radiator
A transitional solution that slightly facilitates the process of replacing the heat exchanger is to dismantle only the dashboard. In this case, the heating installation opens, but remains in the standard location. First you only need to remove the gas pedal and the central tunnel. The ability to move the heater greatly facilitates the dismantling of the radiator.
As a result, we have the fact that the complexity of the repair is due to the inconvenient location of the heating installation - behind the center console of the dashboard. Independent replacement of the heater radiator with Kalina is possible in three ways:
- fundamental, according to which it is necessary to remove the entire instrument panel assembly with the heater;
- combined, involving the dismantling of only the dashboard (without a heater);
- folk, excluding the procedure for removing the dashboard.
The vehicle's heating system must be working properly. It is not difficult to achieve uninterrupted operation of the stove if you know the device. The heater creates a comfortable stay in the car, creating an overview for the driver.
The device of the stove provides for the use of options for small-class machines. 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 models of Lada Kalina were developed, which were already equipped with additional options:
- Electric lifts of glass doors.
- Reliable heater.
- Heated seats.
- Cabin air conditioning unit.
The Lada Kalina heater device is designed for heating and cooling the car interior. If the car is not heated, the windows fog up, you feel discomfort, then you need to test the performance of the heating system. Understand the functioning of the stove on Kalina.
The general layout of the Kalina stove
The location of the stove was designed for easy installation of an air conditioner. The system is simple, but at the same time quite reliable.
- Left side stream outlet.
- Left duct.
- Heated side glass.
- Air flow splitter.
- Stove.
- Right ventilation duct.
- Right side exit threads.
- Lower heating duct.
- Cabin heating duct.
- Central outlet for ventilation flows.
The supply and exhaust principle is used. The air masses inside the car are heated by a special fluid that simultaneously cools the engine. The principle of operation of the Kalina stove is based on the fact that the liquid warms up the radiator, where heat exchange takes place, and the heated air passes into the cabin through the air ducts.
If you analyze the Kalina heater, they will differ in equipment. The first option is a simple and reliable design. And in the other - full electronic control. The air passes through the filter into the air intake, and then the fan blows further through the system. The engine is running and warmed up. Antifreeze moves through the system in which the stove radiator is involved.
The amount of air that is heated by the stove radiator is regulated by a damper. It controls the operation of the fan and dampers by a block located on the central panel.
Heating device control unit
- Temperature controller. Change the heating of the air flow by turning the knob. The blue zone produces cold air, the red zone produces warm air.
- Tumbler. Turning the knob clockwise adjusts the intensity of the air flow. Choose from 4 fan speeds.
- The selector of division of air streams. Distributed in specific areas:
Streams pass through the upper part of the cabin.
The air is directed downward.
Air flows are directed to the windshield and down.
Air flows are concentrated in the area of \u200b\u200bthe windshield, as well as side ones.
- The handle that controls the recirculation of cabin air. Turn on the mode when driving off-road or in a traffic jam. It is used for a short time, the glasses fog up.
- The switch of a mode of a warming up of back glass.
We regulate the direction and saturation of air flows through aerodynamic devices. We turn the guide vanes and change the position of the dampers to achieve the desired air direction.
Interior ventilation Lada Kalina
Outlet pipes are located in the body plumage of the car under the trunk. The heater is located under the dashboard. The air flow enters the interior of the car through the intake, which is designed in front of the windshield in the engine compartment. Air enters through the filter and accelerates through the cabin under pressure, which creates a fan.
1. Branch pipes for supplying air to the rear of the cabin.
2.Side ventilation nozzles.
3.Blowing the side windows.
- Windshield blower nozzle.
5-6-7. Central deflectors for the flow into the passenger compartment.
We direct the supply air through the deflectors by turning the handwheel. If we turn up, the damper opens and vice versa. You already understood how the stove on Kalina is arranged.
- Mode switch.
- Resistor.
- The electric motor of the stove.
- Egnition lock.
A. To power supply.
Checking ventilation and stove Lada Kalina
Car owners claim that the Kalina heater heats much better than previous VAZ models. It sometimes breaks down and needs repair. Run a full system diagnostic to make sure it works.
- We start the car engine.
- Turn the left knob counterclockwise and place it in the blue area.
- We put the fan speed switch in turn in each of the 4 positions. If the fan does not rotate in one of the positions, then we check the power supply circuit of the device.
- Set the speed controller to maximum.
- With the right handle (flap control), we check the redirection of air flows. If we notice that there is no change, then the damper actuator needs to be repaired.
- Warm up the engine to 90°C. Turn the left knob to the extreme position of the red zone.
- The air that comes out of the panels should blow warm air.
- Return the left handle to the blue area. Cold air will come out of the nozzles again.
- If the temperature of the air flows does not change from changing the position of the regulator, then the control of the central damper drive is faulty.
To understand that the Kalina interior heater, the scheme of which is simple, is damaged, the car owner may not immediately. You constantly add antifreeze in small quantities, and the carpet in the cabin is dry and there is no smell of antifreeze. The leak of the stove does not appear immediately, and most importantly, the liquid can evaporate. There are no outlets to the interior of the radiator on Kalina that can leak.
Possible malfunctions of the heater
Yours or weakly warms. Look for the cause of the malfunction. The fan does not work or the heater radiator flows - obvious breakdowns that occur at any time.
Stove control unit :
- The engine warmed up, but warm air did not enter the cabin.
- It is possible that the throttle control cables have come off. The only solution is to remove the console.
dampers . Open or close partially. A rubber seal has come off in the air duct or third-party objects have fallen.
Antifreeze circulation . Start the engine and check the level in the expansion tank, as well as for any violations of the normal movement of antifreeze. Possible reasons:
- Pump. Cannot be repaired, only replaced.
- The cooling system is clogged. Clean or rinse.
Thermostat check . Warm up the engine to 75°C. If the upper pipe is cold, then the thermostat does not work correctly, does not open the movement of the coolant in a large circle. Replace device.
Airlock . 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 supply is weak and there is no desired temperature, then replace the filter. Be sure to check the stove 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 is responsible for the operation. If the fan is on and its operation is accompanied by third-party sounds, clean or replace.
dampers . It is difficult to determine the breakdown, unless you replace the dampers themselves.
The reason for the malfunction of the heater may be the depressurization of the cooling system of the car engine. The breakdown options that are described above cause malfunctions in the operation of the stove of the Lada Kalina car. Such breakdowns do not require special knowledge, it is easy to understand and repair.
Summary
The car Lada Kalina is produced with an installation for ventilation and heating or with an air conditioning system. For the first option, it is impossible to provide a cabin climate, the temperature of which will be lower than the environment.
Information on how to change the stove on Kalina on your own is very popular for all motorists who have ever encountered malfunctions of this VAZ 2118 unit.
The heating and ventilation system of Kalina itself is quite simple, but it is very difficult to get to its elements hidden behind the front panel (dashboard). Therefore, issues related to malfunctions of the cooling system in general and the stove radiator in particular deserve detailed consideration.
Cooling system problems
Most often, owners of a Lada Kalina car have to deal with such malfunctions:
- engine overheating due to untimely switching on or failure of the main fan;
- the stove fan fails;
- the stove tap or the radiator itself is leaking, which leads to a complete replacement of the Kalina heater;
- the VAZ 2118 power unit does not warm up to operating temperature due to the fact that the fan is constantly running.
The forced cooling of Kalina is controlled by the electronic control unit (ECU), focusing on impulses, which transmits the temperature sensor for turning on the fan. When the antifreeze in the upper pipe heats up to 103-105 ° C, this sensor sends a signal to the computer, which starts the impeller through the relay.
If the fan switch-on temperature is reached and the cooler is not started, then the malfunction lies in the sensor itself or in the relay contacts.
When the cooling fan does not work, this threatens to overheat the engine, leading to the replacement of the piston group. But if the impeller is constantly spinning, regardless of temperature, then you must immediately open the block relay. In one of them, which is responsible for the operation of the cooler, the contacts are probably stuck. A decrease in fluid temperature or overheating of the engine can also be caused by a jammed thermostat, which must only be replaced.
Also, only replacing the stove on Kalina can correct the situation when a leak appears in her radiator. The reason is that factory elements are made of aluminum and cannot be soldered. It often happens that the heater fan does not withstand harsh operating conditions and fails. Here, too, only the replacement of the stove motor will help.
The trick is that the first group of faults after the correct diagnosis is eliminated quite easily. It is not difficult to change the fan switch sensor or clean the relay contacts. Installing a new thermostat will take a little more time, but replacing the stove fan or its radiator is another task.
You will have to remove the entire instrument panel, and this is a lengthy process. Therefore, information on how to change the Kalina stove without dismantling the dashboard is so important.
Removing the old and installing a new radiator
Before replacing a leaking stove radiator, you need to prepare all the necessary tools, namely:
- hacksaw blade for metal;
- a set of socket and open-end wrenches;
- pliers, screwdriver;
- a cut plastic canister or basin for antifreeze.
The first and main question: how to remove the stove on Kalina so as not to disassemble the entire dashboard? First you need to empty the cooling system by draining the liquid into the prepared container. Then the air filter is disconnected and removed along with the pipe, and the battery is also removed.
This opens access to the pipes going to the interior heater. They must be removed from the stove fittings by lowering the remnants of antifreeze into the basin.
Next to the fittings, you can find a nut that secures the protective plate located inside the cabin. It must also be unscrewed so that later the plate moves freely and does not interfere with the dismantling of the stove. Then you need to move to the salon and dismantle the following parts:
- Accelerator pedal. It is held on 3 bolts, first you need to disconnect the cable and bend the plate.
- Side decorative panel.
- Plastic side cover of the stove.
- Brake pedal. It is not necessary to remove it entirely, just remove the metal rod so that the pedal rises.
Since the stove fittings stick out in the engine compartment, and its frame does not allow the radiator to be pushed in the right direction, for freedom of action it is necessary to cut out a piece of plastic from the side.
For this, a hacksaw blade is used so that the cut is neat. After that, the stove moves back a little and towards the driver's door, being removed from the nest. A new heater is installed in the same way, and the opening is sealed with plastic that was cut out earlier. The rest of the assembly is done in the reverse order.
When the radiator is removed, it is possible to change the heater damper gearmotor in case of incorrect operation. The reducer and damper position sensor are made as one unit, attached with 3 screws. They must be unscrewed, disconnect the gearmotor and put a new one. Also, with the radiator removed, the stove tap is quietly replaced, if such a need arises.
Removing the blower motor
The stove fan is a fairly reliable unit, but when used in harsh conditions (heat, a lot of dust or high humidity), its electric motor may fail. It is more difficult and expensive to repair a blown motor than to buy a new one, therefore, in such a situation, the Kalina heater fan is replaced.
For the production of work, you need a standard set of tools, and even socket wrenches "under an asterisk". Such grooves have all the screws that will have to be unscrewed during the disassembly process. The latter begins with the removal of the outer plastic grille and the removal of the cabin filter.
All debris from the landing nest must be removed so that it does not fall on your head during the dismantling of the stove fan.
Replacing the heater motor will require you to take an acrobatic pose inside the Kalina cabin, if you do not remove the front passenger seat in advance. Its skids are fastened with 4 nuts, so this operation will not take much time.
Then you need to open the glove box, free it from things and unscrew 4 screws located on its back wall. Another screw is located outside, under the air grill, it must also be unscrewed.
Further, a decorative trim is removed from the right front pillar, 2 self-tapping screws for fastening the plastic panel and the airflow unit are found below it. They are unscrewed, the airflow unit is removed and the plastic panel is lifted (it is held on by Velcro).
There are 2 nuts under it, they should be loosened with a socket wrench. To remove the stove fan, you need to move the dashboard as far as possible and fix it in this position.
The last step is, lying on the floor of Kalina, remove the stove fan by disconnecting the electrical connector. It is necessary to rearrange its turbine to a new electric motor. Then the unit is installed in place, and then assembly work is carried out. The replacement process is shown in detail in the video.
Probably, every motorist, regardless of the cost, class and prestige of the car, faced various kinds of breakdowns. No wonder there is a joke about a well-known British brand whose cars can only move in the direction of a car service. But it's not about him now. The domestic auto industry also has problems that require immediate solutions. For example, if you have a Lada Kalina, replacing the stove radiator is inevitable.
A little about the device
It just so happened that Russian winters are among the coldest, which means that cars should be produced taking into account this small feature. In such weather conditions, a powerful stove becomes an undoubted advantage of Kalina. It will not only bring the interior temperature to an acceptable minimum in a matter of minutes, but will also warm its owner with the warmth of a Russian automotive heart. However, there is a small minus in this device - over time, you begin to notice how the main heat source is leaking, forming oily drops on the rubber mats.
At this moment, it is worth starting to sound the alarm and think about the need to replace the stove radiator on Kalina. Antifreeze turns out to be oily drops, which can not only stain the rug, but also flood the electronic control unit, which, in turn, will bring a lot of problems.
How to find a radiator?
On Kalina, the stove radiator is located somewhat differently than on other cars of the VAZ family.
In order to get close to it, you need to remove the central panel just below the located audio preparation or radio and look to the right of the gas pedal. It is located slightly above the electronic control unit.
Causes of leakage
Often, the radiator leaks during the cold season, since it is made of materials that are unable to adequately withstand temperature changes. The solution is only to replace the stove radiator on Kalina. It will not be possible to insulate or protect it. The only thing that can be done to minimize losses is to wrap the control box in a film that does not allow moisture to pass through.
How to replace the heater core?
You can go one of the chosen paths.
1. Trust the professionals and hand over the car for service.
2. Try to solve the problem yourself by spending a whole day taking apart half of the car.
3. Without removing the panels, complete all work in half a day.
If you see the item "replacement of the stove radiator on Kalina" in the price list, the price is unlikely to pleasantly surprise you. The cost of the service is about five thousand rubles. After this, you will want to spend the whole day, invite friends and, having dismantled a considerable part of the car, replace the radiator yourself. But do not rush with this either.Replacing the radiator of the Kalina stove without removing the panel, although a rather laborious process, due to some inconveniences, is the fastest.
Without removing panels
There are many options for replacing the radiator, in which you do not remove the panel. Let's stop at one of them.
1. The first thing we need is enough room for action, namely the ability to fully open the driver's door.
2. After that, open the hood to disconnect the air filter along with the air duct, and also remove the battery along with the platform.
3. Drain the antifreeze.
Remember that it is under pressure while the engine is running. Therefore, perform all actions, first making sure that nothing threatens your health. Wait until the engine has completely cooled down.
4. Now you can dismantle the old radiator.
Disconnect the pipes attached to the engine fittings. Then we find the same fittings, but already on the stove radiator, and remove the pipes from them. Thus, we disconnected two hoses leading to the stove.
Having done these simple operations, you can see that there is a nut between the hoses, with which the metal casing is attached to the motor shield. It needs to be unlocked.
Replacing the stove radiator on Kalina is in full swing.
We remove the gas pedal and loosen the nuts on the brake pedal to move it a little to the side for ease of work. Why not remove the brake pedal? Firstly, this is not the first necessity, the pedal will not hurt much, and secondly, it will still not work to remove it.
So, we have completely freed up space and now we can remove the old radiator.
Remember that it is in a casing that will need to be cut a little. Since everything is very compact and there is too little space between the radiator and the panel, it will not be possible to easily remove the broken part. We ruthlessly cut off the tubes, release the radiator from the fasteners and take it out of its rightful place.
5. We install a serviceable part.
Picking up a new radiator, you will immediately understand that he does not want to get up in his original place. Interfere with plastic tubes attached to the structure.
What to do? Cut them off about an inch. When dismantling, we removed the hoses, which means that they need to be put in place. Before doing this, heat the plastic edges of the tubes with a regular lighter, and then press it against any surface, preferably metal, so that an obstacle forms and the hoses do not come off in the future.
Now you can install the heat exchanger in place. The whole procedure is performed in reverse order.
So the stove radiator ("Kalina") was replaced. The price of the materials used is several times lower than the cost of the service in the service.
The final step is to fill the antifreeze. Don't forget to release any air that has formed as well.
Results
After completing all the work and enjoying the warmth in the cabin, we can say that replacing the stove radiator on Kalina does not take as much time as it seemed. And the invaluable experience gained during the repair work allows you to be proud of yourself and your skills.
