Every car enthusiast wants to have an air conditioner in their car when it is very hot outside. So, on the Lada Kalina, this function is not provided by the manufacturer. But the popular “Kulibins” figured out how to install air conditioners, and some manufacturers picked up the idea and began producing universal cooling systems for the interior.

How to install an air conditioner
Proper installation of an air conditioner is not only about connecting hoses and cables, but also mechanically installing all components. In order to integrate the device into the car systems correctly, the technician needs to know:
- engine capacity;
- year of manufacture of the car;
- power steering;
- number of valves;
- sometimes - VIN code.
Without this data, he will not be able to accurately select components and guarantee correct operation of the device. In addition, with the purchase of an air conditioner, the owner bears a whole burden of worries about the condition of the air conditioning system. The device requires annual maintenance, constant checking of the integrity and tightness of all connections. Regular cleaning and refilling of the car air conditioner is carried out if necessary. And this is also an additional expense.
Unfortunately, you won’t be able to save money on installation here. The device is too complex to install with your own hands, and no one can guarantee the quality of the system during self-installation. Companies that do this provide a warranty on the device from one to three years, depending on the status of the company. So it’s better not to save money if cool and clean air inside the car is important in any heat.
Climate control: definition and purpose
This is complex equipment that includes air conditioning, temperature and humidity sensors, a heater, an electronic control unit and a filtration system. The main goal of the climate system is to create a microclimate in the car interior that is comfortable for the driver and passengers, as well as to maintain it. The following conditions are considered suitable for humans: temperature – from +22 to +25°С, humidity – from 65 to 80%. Climate control analyzes these indicators and then heats the air in the cabin (using a stove) or, on the contrary, reduces its temperature (thanks to air conditioning).
Is it possible to install an additional climate system?
In almost all modern cars, climate control is included in the list of basic equipment. This system is equipped with various types of vehicles - from cars and buses to self-propelled vehicles and special equipment.
You can install the system additionally - as a rule, many car enthusiasts refuse air conditioning in favor of it. However, it should be remembered that installing climate control is not possible on all cars, because this requires a stove of a certain configuration that would allow the installation of a servo drive and wiring under the “dashboard”.

How to fill it yourself?
Before you start refueling, you need to get rid of moisture and air using a vacuum pump.
Filling the climate system with freon consists of the following sequence of actions:
- The car needs to be put on the handbrake and put in neutral.
- Before connecting the filling kit hose to the low pressure port, it must be cleaned of dirt.
- When the hose is connected, you need to start the engine.
- The second hose should be connected to the freon cylinder.
- During refilling, you need to press the gas pedal so that the refrigerant is evenly distributed throughout the air conditioning system. Cooled air should enter the cabin.
- When refueling is complete, remove the hose from the low pressure port and screw on the cap.
This completes freon charging. Now you need to turn on the car air conditioner and check how it works.
Every car enthusiast wants to have an air conditioner in their car when it is very hot outside. So, on the Lada Kalina, this function is not provided by the manufacturer.

This video will help you understand how to install an air conditioner on a car and will give you recommendations and advice.
In order to install air conditioning on the Lada Kalina, you will have to buy a few spare parts. So, what do we need to feel comfortable on the road on hot days:
- Compressor.
- Air conditioner radiator.
- Receiver.
- Evaporator.
- Control unit and sensors.
- Copper or aluminum tubes.
- Service valves.
All these spare parts can be purchased separately or all in one package. For Kalina, such a kit will cost the owner an average of 15,000-20,000 rubles. But you have to pay for pleasure.

Preparing for work
Experts, car owners, as well as manufacturers of car air conditioning systems do not recommend installing an air conditioner in a car yourself. This is connected, first of all, with security, and secondly with the technical side of the issue. That is why, on the instructions you can find the following note: “It is not recommended (prohibited) to install the system not at a car service center.”
Installation diagram of the air conditioning system on Kalina
If, nevertheless, the car enthusiast decides to install it, then it is necessary to study the instructions in detail and lay out the parts in sequence on the asphalt or ground. Make sure that the equipment is complete, and also design and install mounts on the car.
The process of installing an air conditioner on a Lada Kalina
Now let's get to work. Let's start installing the air conditioner on the Lada Kalina:
- It's best to remove the hood too.
- We will assemble the entire system on an open surface to make sure that everything is there.
- We install the radiator. It is installed in front of the main cooling radiator. Installation of the Kalina air conditioner radiator
- Now we install a compressor that will spin from the generator. It is best to replace the alternator pulley. If the condition is good, then it can be left the same. The second option is to install the belt directly on the crankshaft, but we do not recommend it. To install the compressor, there are special aluminum plugs on the block that can be unscrewed with a screwdriver.
- The evaporator can be mounted under the hood or in the cabin, but it works best next to a firewall.
- We attach the dryer to the body mudguard under the hood.
- Laying the pipes. Connecting the air conditioner dryer to Kalina
- We cut the air conditioning system into the ventilation system and connect the air flow regulator.
- If the air conditioning system has an electronic controller, then it must be connected to the system itself and also powered.
- We check the correct connection and tighten the connecting bolts.
- Now, you need to fill the system with freon using a special device for refilling air conditioners.
- We are testing the system.
If everything is connected correctly, then the interior of the Lada Kalina will become cool, and if not, then you need to look for a fault.
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.
The car owner may not immediately understand that the Kalina interior heater, the circuit of which is simple, is damaged. You constantly add antifreeze in small quantities, and the carpet in the cabin is dry and there is no smell of antifreeze. A stove leak does not appear immediately, and the main thing is that the liquid can evaporate. The radiator on Kalina does not have pipes leading into the cabin that could leak.
Factors influencing the choice of air conditioner in a car
If you have found a specialist who is ready to begin installing a car air conditioner, the next mandatory step is choosing a device that would suit all parameters for your car model. As a rule, such information is indicated in the manual (operating instructions), in the section on additional devices. The type of air conditioner should be chosen based on the power of your power unit. Any auto store specializing in the sale of car air conditioners will provide you with a fresh catalog of climate systems, from which you can easily select a device that fully matches the characteristics of your vehicle.
It is important to check how complete the equipment of the selected car air conditioner is. A typical air conditioning system should include:
- compressor with belt;
- evaporator;
- condenser (popularly this unit is usually called the air conditioner radiator);
- receiver-dryer;
- connecting tubes, interfaces, sensors, safety valves;
- device control unit;
- other necessary components present in the inventory of the purchased kit;
- Installation instructions for car air conditioning in Russian.
Note that if your car was manufactured after 1993, the filling fluid for it will be R134a freon, otherwise you need to fill the system with R12 freon. It is also necessary to decide which type of air conditioner to give preference to: manual or automatic. The former are single- and multi-zone; automatic devices that cool one zone are extremely rare.
The operating principle of the air conditioner on Kalina and the refrigerant flow diagram
The cooling system of the Lada Kalina 8 cl and other models is similar in design. The compressor that ensures the operation of the system is located on the BC of an engine with 8 cells, etc., and operates when the belt rotates. The temperature in the cabin is regulated using a special knob on the climate control panel.
The car air conditioner, both for 8 cl engines and for others, is a sealed system that is filled with refrigerant. The unit operates by rotating the belt. The freon in the compressor heats up greatly due to the high pressure and flows through the pipeline into the air conditioner heater, where it cools. The gas is cooled thanks to the fan, which begins to work together with the compressor.
Having cooled, the freon condenses and turns into a liquid state, and then enters the receiver-dryer. The refrigerant then passes through the expansion valve and enters the evaporator. Here it turns into gas and cools greatly. At the same time, it cools the evaporator. Thanks to the fan, cooled air is blown from the evaporator and enters the cabin. The cold refrigerant returns to the compressor. So the process is repeated in a circle (the author of the video is L0RlC).
ODS device of Lada Kalina
Kalina 1 and Kalina 2 cars use a liquid cooling system. It consists of an engine jacket, radiator, electric fan, pump (water pump), expansion tank, thermostat and connecting hoses. The coolant moves through two circulation circuits. In a small circle, antifreeze circulates only through the engine jacket, while in a large circle, the liquid passes through the radiator.
Expansion tank
Used to pour liquid into the system. It is made of heat-resistant plastic of a translucent color to allow you to control the level of antifreeze. There is a special pipe on the top through which the tank is connected to the radiator steam outlet.
The tightness of the entire system is ensured by the valve cover, which has inlet and outlet valves. The latter is designed to maintain pressure in the SOD above atmospheric pressure. Due to this, losses in the form of steam are reduced, and the boiling point of the working fluid increases. The exhaust valve of the cover opens when the pressure rises to 1.1 bar, and the inlet valve opens when the pressure drops to 0.13 bar and the engine cools down.
water pump
This is a centrifugal pump with blades. It is belt driven from a crankshaft pulley and is included in the gas distribution system. The pump is made of aluminum. This unit cannot be repaired; if it fails, it can only be replaced. Rotation occurs due to a double-row non-separable bearing; its high-temperature lubricant is designed for the entire service life. There is a toothed pulley at the front and an impeller at the rear.
Thermostat
Designed to redistribute coolant flows, it contains a temperature-sensitive element and two valves. When the engine cools down, one of the thermostat valves is in the closed position, and fluid circulates through the motor jacket - only a small circuit is used. As the temperature reaches 85 degrees, the second valve begins to open slightly, allowing antifreeze into the radiator and closing the bypass channel. Full opening occurs at a temperature of 100 degrees. In this case, all the liquid begins to pass through the cooler.
Engine radiator
The heat exchanger can be monolithic aluminum, tubular, or plate type. Its device uses two plastic tanks that are connected by tubes. The upper one is inlet, and the lower one is outlet, through which the cooled liquid is sent back to the engine. Near the first there is a steam outlet connected to the expansion tank. The radiator on Kalina is complemented by an electric fan. There is a drain plug at the bottom of the outlet tank.
The cooling system is complemented by a heater radiator, which is integrated into the ODS and is used to heat the air in the cabin, since hot antifreeze also passes through it. The controller monitors the coolant temperature using a sensor that is installed in the cylinder head and transmits readings to the instrument panel. To transmit a signal to the controller, a sensor installed on the exhaust pipe, near the thermostat, is used.
Differences between modifications with air conditioning
Some configurations of the Lada Kalina are complemented by air conditioning, which is part of the climate control system and is used to cool the air in the cabin. The device cannot operate if the outside temperature is below 5 degrees, the engine is not running, or the heater fan is on. The air conditioning compressor is driven by the engine, and this is the main disadvantage of the installation.
About refilling the air conditioner
You need to pump 500 g of refrigerant into the Priora air conditioner. Until 1995, R12 freon was pumped into air conditioners, but it was considered toxic due to its high fluorine content. Therefore, R134A freon is now in use. Preparing for refueling looks like this:
- special cleaning foam from a can is pumped into the air conditioner radiator;
- the radiator closes. The car engine starts and idles. At the same time, the air conditioner turns on. It must run for at least 15 minutes so that the foam passes through the entire recirculation system;
- vacuum is performed. A pump is connected to the air conditioner, which removes air from the system along with foam and moisture.
Refueling
To refill the air conditioner, the driver must purchase a metrology station and a can of freon.
High pressure hoses in the station are always red, low pressure hoses are always blue
The station is a system of hoses, adapters and pressure gauges connected to the air conditioner.
- The station hose is connected to the low pressure fitting on the air conditioner pipeline (it is usually painted blue or has the English designation “low”).
- The engine starts and idles, and the number of revolutions per minute should not be lower than 1400 (for this you will have to fix the gas pedal with something, or ask someone for help).
- When the engine is running, maximum recirculation of the air conditioner is turned on, then the low pressure valve at the station smoothly opens.
- The freon cylinder is turned upside down, after which the tap is opened on it.
- The refrigerant begins to flow from the cylinder into the system. At the same time, the driver controls the pressure using a pressure gauge - it should not exceed 280 kPa.
- When the air in the cabin warms up to a temperature of 10–15°C, refueling stops.
"Pitfalls" of using an air conditioner
On a Lada Kalina with a station wagon body and a 1.4 liter engine, the use of air conditioning gives rise to many problems. When the car is fully loaded with passengers in urban conditions and the air conditioning is running at full power, the engine loses its dynamics so noticeably that it may stall when the car starts moving. Fuel consumption in this situation reaches 15 liters per 100 km. However, the air conditioner can be used in other ways, which will give the engine more freedom.
Firstly, you can turn on the air conditioning not when it has already become hot, but at a normal temperature in the cabin, but when the outside air begins to warm up. Ideal if you left in the morning and have to spend a few more hours on the road in the afternoon. A comfortable temperature in the car will be maintained throughout the trip, and engine power will drop slightly.
Diagram of operation of a car air conditioner
It is not necessary to turn on the air conditioner immediately after parking the car outdoors. It is best not to start moving immediately, but to stand for a while with the doors open. Only after this can you close the windows and start the engine. Turn on the air recirculation mode, and after 5 minutes the temperature in the cabin will become comfortable, after which the air conditioner should be switched to minimum mode.
The 1.4 8 cl engine on Kalina with the air conditioning on can sometimes sharply gain speed at a constant throttle position, or sometimes lose it, while the driver does not release or press the gas pedal. In some cases, for example when overtaking is necessary, this feature can become an unpleasant surprise. Therefore, when the air conditioning is on in Kalina, it is better to keep a greater distance from other cars.
Installation of foreign-made climate systems
Lada Priora air conditioner "August" is one of the most inexpensive options. If you want to buy a higher quality device, then you can opt for the Hull, Panasonic or Frost systems. In practice, the latest model is characterized by good compatibility with the Priora heating system, due to which the air flow filtration will be of better quality. As for the installation scheme, it is practically no different (the author of the video is Auto World).
But Frost also has its drawbacks: it happens that the installation gets very hot, does not cool the air well, and generally does not cope well with its assigned functions. But even if the unit works well, it will take longer to cool the interior. This is because the compressor itself is not particularly powerful. But despite the disadvantages, Frost also has advantages. When the air conditioning is turned on, it will generally not affect the functionality of the vehicle.
It should also be noted that the air conditioning units of this manufacturer were tested in African countries, and this says a lot. In particular, during testing, the installation cooled the interior well, while the engine of cars of various brands did not overheat. On sale you can find several variants of Frost condensers, which differ from each other only in the installation method
When installing the device, you will need to remove the heating system damper, but this will allow you to install an air filter, which is no less important.
In any case, when purchasing, you should focus on your preferences, as well as your budget.
If the device gets very hot, you need to pay attention to diagnosing all its components and components. As a rule, this problem is caused by the need to replace the radiator
In addition, during operation, one should not forget about refueling the system, as well as its periodic cleaning. We have already written in more detail about how to clean the air conditioner on your own using improvised means; you will find information about this here.
Installation
Frost and similar refrigeration units can be installed on Kalina with both a 16-valve and an 8-valve engine. The price of the equipment itself is 20-30 thousand rubles. They charge a considerable amount for installation on services. Is it possible to install the climate system yourself? You will have to disassemble almost half of the car and spend a whole day on it.
This step is mainly taken by those people who purchased a car when it was not equipped with air conditioning, or who did not have the money to purchase a Lada Kalina with an already installed refrigerator. This includes those who did not like the standard climate control system. To install an air conditioner on Kalina, you will need to remove the dashboard, but in some cases it is not necessary to completely disassemble the panel.
First, you can remove the glove compartment and bend the plastic plate hiding behind it. The stand plate is also removed after unscrewing the screws holding it using a screwdriver. Remove the dashboard and air filter housing in the engine compartment. Return to the cabin and remove the heater motor housing. To do this, you will have to tinker a little with the sound insulation that prevents you from unscrewing it. Bend back a small section of the soundproofing coating, unscrew what is needed with a ratchet, move the heater receiver, and remove the connecting air duct.
In order for the Shumka to fit under the air conditioner, it must be carefully trimmed. When you move the dashboard and remove the center console, you will see the very place where the evaporator of the cooling system fits perfectly. After this, you need to install a temperature sensor under the console. Some Kalinas may not have it, but you still have to install it. Be sure to seal the space between the engine compartment and the evaporator with a soundproofing coating.
Installation diagram of an air conditioner on a car
Particular attention should be paid to the installation of Kalina electrical wiring. It must be done in such a way that nothing interferes. It is possible that the crankcase protection will also have to be temporarily dismantled for this reason. Only after these operations are the pipeline laid and final assembly carried out.
How to fill it yourself?
For Lada Kalina, it is recommended to purchase R-134a freon. For refueling, use a special refueling kit, which has two hoses and a ball valve.
Filling the climate system with freon consists of the following sequence of actions:
- The car needs to be put on the handbrake and put in neutral.
- Before connecting the filling kit hose to the low pressure port, it must be cleaned of dirt.
- When the hose is connected, you need to start the engine.
- The second hose should be connected to the freon cylinder.
- During refilling, you need to press the gas pedal so that the refrigerant is evenly distributed throughout the air conditioning system. Cooled air should enter the cabin.
- When refueling is complete, remove the hose from the low pressure port and screw on the cap.

Video “Features of installing a condenser on a Grant”
The main nuances that should be taken into account when installing the air conditioning system in a Lada Granta car are shown in the video below (the author of the video is the Automotive Service channel).
Please tell me if anyone has installed a regular vent air conditioner in a car. There is an idea to install Samsung 5 in a cargo-passenger GAZELLE. Which option is preferable: a 220 inverter or a 12 compressor?
100% 12 volt compressor, because... A 220 volt converter consumes a lot of current.
It won't have time to eat it, it will burn faster)))
Well, why be so categorical? A properly manufactured converter will live and work for a long time. The only thing that makes me happy is questions like - I want to feed the converter from a Zhiguli battery that consumes a current of 100 Amperes...
I just have experience in repairing converters, they take 800 W, and connect the kettle to 1.5 kW, and the reserve must be taken at least 2 times, otherwise you won’t survive))_) I’ve seen a maximum of 2.5 kW and it’s homemade, a pig in a poke))
Here, as they say, you can foolishly break your penis. There is just mass psychosis about these converters based on the illiteracy of the masses. 2.5 kilos is 100 amperes, I just wonder how many minutes it will take to discharge a 12 volt battery to zero. Even if you take a 24 volt battery, it won’t last long
What if you put a 24 in the generator and a pair of 12 in the battery, respectively?
Don't ask a question - just ask. You can also install an alkaline battery from a car, but there’s no need for it. It’s easier and cheaper and less troublesome to install a gas generator to generate electricity at 220 volts
cool)) the most interesting thing will happen if you calculate the economy:
compressor price+compressor installation+refrigerant line+system refillingVS gas generator price
besides, a generator is such a thing... as soon as it appears, you immediately find a lot of work for it)))
What if you stupidly take a compressor from a car with an air conditioner, put it on the engine, and connect the pipes to the window?
Either turn the compressor with an electric motor and put everything in the window housing, or even google 12v compressors and, of course, install a powerful generator.
just triple power loss. for what?
yes, the installation will just be removable “mobile”)))
I think that there will be losses due to the long length of the tubes. The compressor is under the hood and the air conditioner is near the cargo compartment.
There will be no losses, but it’s better to cool the freon after compression
we touched on a cool topic))) a bad thought has been drilling into the brain for a long time, if you take the smallest slab, and a small gas generator for it, the question is whether the slit will be killed by shaking (after all, a gazelle is not a Merc) and how long will the connecting tubes from the block to the atomizer last, or whatever he is...
look
Well, it’s a window unit, but I’m interested in a split unit, so that without major changes, an external unit for the roof under the fairing, an internal one for the interior under the seat
yes, in principle, this is the same split system, only for cars, but its price is sky-high...
Have you looked at the system in the German seven?
no, but in more detail...
thanks, I'll take a look now
well, about the outboard... its price is the same if from the Japanese, what kind of Kruzak thread to remove all the stray stuff is the same price... and again you need to stir up the compressor for the engine... but I’m wondering whether the split will be killed if you put it on the roof, it’s easier for me under Attach a mini petrol generator booth for 220 to the split rather than climb into the engine and remove the panel...

here it is, all you need to do is buy cars with air conditioning =)
At the time of purchase they were not with the 2008 A/C, if I'm not mistaken,
clear/understandable... mine is 12 years old, I took it right away with an air conditioner, even though we are in the far north, it’s more pleasant at +30 with an air conditioner =)
At the time of purchase they were not with the 2008 A/C, if I'm not mistaken,
What controls the operation of the air conditioner? ECU or climate control unit?
If the air conditioner is not standard, then the climate control unit has cables; for the air conditioner you need an electronic one, with motors on the dampers instead of cables. Therefore, the kit usually includes separate wiring with sensors and a knob-regulator. Also, the power button is connected to the computer, which controls the A/C clutch relay. This was done for: 1. Adjusting the ECU mixture when turning on the air conditioner and compensating the load 2. Disabling the clutch when “gas to the floor”, when the ECU believes that overtaking is in progress and frees up engine power for this.
It's clear. You can try to run it without the ECU...
Is there anything else I need to buy besides the kit? Well done. But does the controller firmware need to be changed? I changed the stove. Gas equipment was supplied. I installed the electric power steering, it's time to install the air conditioner. But I don’t want to change my car.
This is certainly a feat! If replacing a heater radiator on a Kalina is an initiation into Kalina waters, then installing a candik in a Kalina is the 80th level of coolness out of 80! Consider saving another 30,000 rubles. they wouldn’t have taken on installation for less money)))
HEALTHY BRO! Tell me, I want to clean the evaporator! How can I get to it without draining the froin? thanks in advance!
Hello, maybe we are talking about antifreeze?
