During operation, a car engine inevitably gets hot, and to prevent its parts from overheating, a cooling system is used. One of its most important parts is the radiator, in which the coolant cools to optimal temperatures. This prevents excessive heating of the power plant parts. Without cooling, the engine will inevitably overheat and fail.
Replacing a Priora radiator with halla air conditioning
With the onset of cold weather, car owners begin to use the interior heater.
Lada Priora is a fairly warm car with a well-designed interior heating system. But there are times when, with the onset of cold weather, the interior is cold and the culprit for this is the heater radiator, which is what will be discussed in this article. Priora is a car with an increased level of comfort. In the “luxury” configuration it is equipped with a climate control system with Halla air conditioning. This installation is quite reliable and easy to maintain.
It is necessary to monitor the condition of the heater and keep it clean. To do this, you need to change the cabin filter in a timely manner to protect the heater radiator from contamination. You can read how to properly replace the cabin filter here.
Connecting the air conditioner to the on-board network
After installing all the elements and pipes of the air conditioner, it must be connected to the car's electrical network.
Here's how it's done. A pressure sensor included in the air conditioner kit is mounted on the high-pressure pipe. A relay unit is mounted in any free space in the engine compartment
Its wiring is connected to the air conditioner in accordance with the diagram supplied with the device.
The common wiring harness is pulled into the passenger compartment, where the contacts are connected to the vehicle's electronic control unit, to the heater control unit and to the air conditioning buttons.
Particular attention should be paid to the air conditioner fuse. It is located in the mounting block under the steering column. In the diagram it is designated as F9
In a Priora without air conditioning, this fuse is responsible for the condition of the standard heater. After connecting the air conditioner, it will also be responsible for the recirculation unit
In the diagram it is designated as F9. In a Priora without air conditioning, this fuse is responsible for the condition of the standard heater. After connecting the air conditioner, it will also be responsible for the recirculation unit.
Radiator replacement
The first thing you need to do before replacing the heater core is to prepare the tool.
Required tool:
- Screwdriver "" or "-";
- Ratchet with a “13” head or a “13” spanner;
- Sealant;
- Antifreeze 5l;
- Container for draining antifreeze;
After preparing the tool, you can start working
If the radiato is clogged from the outside:
Replacing a radiator on a Prior with Halla air conditioning
It happens that when using a car without a cabin filter, excess debris may fall onto the radiator of the heater, which under the influence of the heater fan can clog it.
In order to eliminate this ailment, it is enough to remove the radiator and wash it.
Fan doesn't work
But sometimes another problem occurs with the Priora stove. The driver turns the heater switch, and in response there is silence. The electric motor is not working. What is the reason. There may be several of them:
- The fan motor burned out.
- The heater control unit has failed.
- The fan speed resistor has burned out.
- Broken electrical wiring.
The easiest way to determine if a resistor is broken. In this case, only the maximum speed is turned on, and the stove does not respond to other positions of the handle.
Video of replacing the heater radiator on a Priora without air conditioning
With the onset of cold weather, the driver's interest in the operation of the heater increases sharply. The motorist checks the stove for various faults. In some cases, a radiator failure is detected. How is the radiator of a Priora stove replaced? As a rule, this component cannot be repaired and must be replaced. Having opened the dismantling manual, the driver may discover that the parts in his Priora are located differently than in the instructions. It's all about the air conditioner. The process of removing the heater radiator in older versions of Priora without this option differs from dismantling it in new cars where air conditioning is already present. We will look at both options.
Modern Priors are equipped with Halla or Panasonic air conditioners. There are differences in the operation of the two models, but the location of their installation does not differ, depending on the air conditioner brand, so the process is the same. As an example, we will consider a Priora with Halla air conditioning.
Air Conditioner Installation Guide
Before you complete this task, you need to decide which option you will use. There are quite a lot of manufacturers of air conditioning units on the market today, so the purchased unit must meet the requirements and characteristics of the car. The device must have a long service life, resistant to vibrations that are typical for cars used to drive on our roads. It's no secret that our car enthusiasts are more inclined to trust Conder cars and products in general from foreign manufacturers.
How to replace the cooling radiator on a VAZ 2170-VAZ 2172?
1) Before you start work, drain all the coolant from the radiator (How to drain the liquid, read “here”) and proceed to removing the electric fan (If you don’t remove it, you simply won’t be able to pull out the radiator), to do this, first disconnect the negative terminal with the battery, loosen the bolt that secures it, then remove the air filter housing because it will interfere very much (Read “here” how to do this), well, you can start removing the electric fan, first disconnect the wiring from each other, wiring the electric fan has a connector and block on the side (see photo 1), then unscrew (it’s most convenient to use a wrench) two bolts that secure the electric fan to the casing on the left and four nuts, two of which are located on the top and two below (see photos 2 and 3 below) and then remove the electric fan by pulling it to the top and putting it aside.
2) Next, remove the sound signal, because it will not allow you to remove the radiator (For information on how to do this, read the article: “Replacing the signal on the Lada Priora”) and then loosen all the clamps that secure all the supply pipes to the radiator (see. photos 1 and 2, pay attention to photo 1, there is another pipe indicated by an arrow, so don’t miss it) and disconnect them, immediately after which unscrew the two nuts that secure the radiator to the body (see photo 3) and then remove a holder that keeps the hose from dangling from the hole in the cross member of the engine compartment (see photo 4), and that’s it, you can safely then tilt the radiator towards the car engine and then pull it out of the engine compartment.
Look again at photo 1 above, there the arrow indicates the upper hose, unlike the pipes, it is attached not with a worm clamp, but with a tape clamp, tape clamps are not convenient and after the first unscrewing, it is already difficult to secure the hose with them so that it holds just as tightly, Therefore, replace this clamp (If you have a band clamp) with a worm clamp, it is much more convenient and can be tightened with a wrench or a screwdriver!
Before installing a new radiator or re-installing an old one (if you solder it), check for the presence of two cushions on which the radiator stands (see photo 1), they sometimes still remain in the mounting pins, so look everywhere for torn or lost elasticity cushions, replace them with new ones , as well as remove and check the rubber-metal bushings; if necessary, they are also replaced with new ones.
If you still decide to install the old radiator (Perhaps you simply removed it in order to gain access to other parts), then before installing it, rinse it outside with a stream of water and dry it thoroughly, and by the way, before connecting the pipes back to the radiator, Lubricate them with sealant, a small layer, otherwise the pipes may begin to leak, which will cause you a lot of inconvenience and problems with the constant purchase of coolant!

replacing the cooling radiator on the previous one The cooling radiator enters the cooling system when the engine is running, the coolant moves in a circle, and most of it is in the cooling radiator; when moving at speed, the radiator is cooled by the air flow, so the liquid is cooled and the engine does not heat up much.
To change the radiator in a car, this is useful: you will need all the wrenches that you have in your arsenal, as well as screwdrivers, containers into which you will drain the coolant (or one large tank), and stock up on the last coolant as you need will drain the old one, if it is in poor condition, then it is better to pour good fresh fluid into the radiator and expansion tank after assembly!
Where is the cooling radiator?
It is located in the front part of the body, secured with nuts, they are attached to the TV (the TV is the headlights; it still connects the bumper and side elements), removing the radiator from it is not difficult. Priority, because there is enough space to crawl with your hands, but However, if you stock up on the right keys, the replacement process will be completed even faster, and the collar will be just that, and the hat goes to it.

When do I need to change the radiator?
If it has leaked, the radiator should be replaced to make it easy in the summer, just pay attention in the winter to the coolant, and to be more precise, before its level, if it starts to drop, the entire cooling system will need to be checked and to detect the leak, so to recognize that the radiator is leaking in a certain way, you can only use the best ultraviolet light (this makes the coolant very visible) or by removing it and placing it in a huge water tank (by removing the radiator, you can very accurately determine whether there is hole), before placing it in the radiator, you will need to pump compressed air through the coolant fill hole in the radiator (this hole simply does not need to be submerged in water or plugged well than any other holes to prevent the air from passing 100% and), For more information on how to perform this test, watch the video below:
If the holes in the radiator are not huge, then you cannot change it at all, but simply solder it carefully and for a short time, but if you want to install the radiator and, as they say, forget about it, then it is better to buy a new one, as is usually the case, it is not hermetically sealed, it lasts for a long time, and if a pebble gets into this place, the soldering immediately flies away (this depends on how well the radiator is soldered)!
How to remove the heater radiator on a Priora without air conditioning
Since the beginning of production, AVTOVAZ has installed a heater from the “ten” on the Priora (catalog number: 21110-8101012). The disadvantage of this design was that the heater radiator is removed towards the vacuum brake booster, which allows this to be done. As a result, the heater assembly has to be dismantled.
- Remove the wipers.
- Remove the frill (wind flap).
- Remove the soundproofing of the engine shield.
- Disconnect a bunch of connectors with wires.
- Unscrew the heater mountings.
- Divide the heater into two parts (left and right).
- Remove the right side of the heater (in the direction of travel).
- Move the left side to the side to gain access to the heater radiator.
- Drain the antifreeze.
- Replace the heater radiator.
The whole procedure took several hours. This is shown in more detail in the video:
There is another way to replace it. To gain access to the heater radiator, instead of the heater housing, it is necessary to remove the vacuum brake booster along with the brake pedal. This allows access to the left side of the heater (in the direction of travel) and to the radiator itself.

Difficulty of choice
If it has become noticeably cold inside the car, it is worth checking the car's heating system. Most likely, the problem will be detected in the heater radiator and you will soon have to buy a new one.
The Internet is full of advertisements for the sale of heater radiators for Lada Priora, but how to choose a quality product and not “run into” a fake?
The first thing that should indicate the originality of a part is its price. High-quality spare parts cannot be cheap; manufacturers of original radiators will not allow this.
Second. The original radiator of the car heating system has small cells, i.e. the distance between the vertical slats is minimal, only factory equipment can provide this. Factory equipment “works” only with high-quality metal; the honeycombs should not be too soft.
Manufacturers of counterfeit products save on small things; they do not install “liquid swirlers” in counterfeit radiators, plastic parts that increase the heat transfer of the coolant in the radiator of the heating system. To check their presence, you should shake the part; a specific sound will indicate their presence or absence. If they are made of soft material, this method is useless.
Once the radiator has been selected, it is time to change it. Replacing an old one or installing a new radiator in a Priora requires certain actions.
How does the radiator in Priora work and what functions does it perform?
How does the heater work on the Lada Priora
? As stated above, in the Lada Priora and other domestic and foreign cars the cooling radiator optimizes the temperature of the liquid. Note that the radiator does not have any effect on the cooling system when the so-called cold engine is started. It does not start working at all until the car engine is sufficiently warmed up.
When the temperature reaches a certain point, in particular on the domestic Lada Priora this figure is 85-90 degrees, the thermostat opens and the filled antifreeze circulates through the cooling system. When the “engine” operates at high speeds, in particular, when the car is moving at low speed, and the cooling radiator is unable to cope with its task, and the temperature of the power plant begins to rise again, and then the fan turns on, which forcibly cools the antifreeze, located in the radiator at this moment.
The basic radiator on LADA Priora is made of parts made of brass. This material has high thermal conductivity. The core of the device and its middle part are a kind of plastic structure through which special tubes pass, which are connected to the plates by soldering. The coolant passing through the core of the device is distributed into several streams that run separately. This system allows antifreeze to be cooled much more efficiently.
The radiator tanks are connected to the system by pipes made of rubber. The lower reservoir is equipped with a tap, which makes it easier to drain old antifreeze during replacement. There is also a special tap on the cylinder block. From here the coolant can be drained from the water jacket of the power unit. In general, the design of the heat exchanger is quite simple, but very effective.

Check the tightness of the Lada Priora radiator by plugging its pipes and lowering it into a container of water, supplying air to it at a pressure of 0.1 MPa (1 kgf/cm2). No air bubbles should appear from the radiator for at least 30 seconds. If the radiator does not fit completely into the container, check it sequentially from all sides. 16. Install the priora radiator in the reverse order of removal, first placing the lower mounting pads on the radiator pins and inserting the upper mounting bushings into the brackets.
Helpful advice To eliminate the possibility of coolant leakage in the future, before connecting hoses to the VAZ 2172 radiator, lubricate the radiator pipes with a thin layer of sealant.
17. Install the electric fan and all removed parts in the reverse order of removal. 18. Fill in coolant (see “Replacing Prior coolant”).
Features of repair and overcooking of the VAZ 2112 underbody
What to do if the cooling radiator leaks? a few simple ways
The bottom of all modifications of the family was made of rolled steel. Additionally, to increase strength, stiffening ribs are made.
Cars of different body types have different overall dimensions. At the same time, the wheelbase of all modifications is the same - 2,492 mm. The size and shape of the bottom on all machines also has no fundamental differences.
Family service experience indicates that most often - in 9 cases out of 10 - repairing the underbody of a VAZ 2112 begins with checking the condition of the body side members. Corrosion processes require their strengthening.
When performing work, take into account that the components of the bottom are:
- support platform;
- composite panels;
- threshold extensions;
- amplifiers of side members and cross members;
- connectors.
To digest a separate area, the patch is prepared in advance. Further work is carried out in the following sequence:
- the area is polished, the iron element is welded;
- welds are processed;
- the element is primed, sanded, and coated with an anti-corrosion compound.
Partial replacement is possible only in 1 case out of 10. If the option of individual elements is not suitable, a complete replacement of the bottom is carried out.
If the air conditioner does not turn on
Sometimes the air conditioner categorically refuses to turn on after installation. Here's why this might happen:
- problems with electrical wiring. It is necessary to carefully inspect the wires for damaged insulation and short circuits. You should also check the latches on all terminal blocks. Some of them, being new, do not always fit tightly into place, which leads to an open circuit;
- error when assembling the electrical circuit. This is another common option. Each air conditioner model has its own basic assembly diagram. It is difficult to make a mistake when assembling it, since all the important wires have insulation of different colors. However, an error cannot be ruled out. The solution is obvious: check the instructions again and find the error;
- The fuse has blown. Usually the same F9 that was mentioned above is lit. This can happen due to a short circuit in the electrical wiring, or due to an incorrectly assembled circuit. If the air conditioner does not turn on, you need to remove the fuse and inspect it. If it fails, the thread in it will be broken, and its body will be slightly melted. This fuse must be replaced. Then you should carefully check the wiring. And only after that you can try to start the air conditioner again.
Operating principle of the air conditioner
Radiator cooling fan does not turn on
In a sealed air conditioning system, a refrigerant, freon, continuously circulates, which is mixed with a special lubricant that is resistant to freezing. A compressor is responsible for moving freon through the system, which builds up pressure in the heat pipes. After turning on the air conditioner, freon ends up in the heat exchanger located under the dashboard of the car. The internal structure of this device resembles a honeycomb. Once there, the refrigerant begins to take heat from the hot interior. At the same time, it quickly heats up and turns from a liquid into steam. Since the compressor continuously pumps up pressure in the system, the steam goes into the blown radiator, where it cools, again becoming a liquid, which again ends up in the heat exchanger.
Is it possible to install air conditioning on a Priora?
The Priora initially provides the design possibility of installing an air conditioner. A car owner who decides to install this device on his car will not have to make any modifications. All the necessary holes and buttons are already on the dashboard, and space for heat pipes and electrical wiring is also provided. Thus, installing an air conditioner on a Lada Priora is completely legal, and government officials will not have any questions for the driver.
Symptoms of a problem
The Lada 2170 model received a liquid heater, which is connected to the engine cooling system. The radiator is a heat exchange device; due to this component, the air entering the Priora’s cabin is heated. Coolant constantly circulates through the radiator; this part of the heater is subject to wear.
It is worth checking the radiator in the following cases:
- The stove stopped heating properly.
- The coolant level drops.
Once you disassemble part of the heater system, you will see a rusty and most likely leaking radiator. There may also be leaks in hoses, pipes and the junctions of these elements. You should check the heat exchanger of the stove only after you have made sure that there are no defects in the operation of the gearmotor and damper.
Radiator malfunctions and their consequences
A broken device poses a great danger to the entire cooling system, since its instability can lead to overheating of the power plant. The Lada Priora uses a standard combined cooling system, when the liquid system is supplemented by an air system. Thanks to this combination, it is possible to more effectively maintain the optimal engine temperature under various loads and operating modes.
There are not many malfunctions of this element as such. The main problem with the radiator is the occurrence of coolant leakage. This happens due to a violation of the integrity of the tubes caused by damage to the radiator. Another common problem is clogging of its inner surface. This can be determined due to the constant operation of the forced cooling fan.
The temperature drops, but rises quickly and causes the ventilation unit to turn on again, even when driving at high speed. This is due to the fact that the oncoming air flow cannot cool the coolant due to dirty plates. Contaminants can also be deposited on the inner walls of the radiator tubes, which will impede the circulation of antifreeze. And, as a result, the engine will begin to heat up excessively.
When the device is broken, the power unit overheats.
Causes of malfunctions
The main factors causing problems with the radiator are the following:
- wear of elements of a natural nature (any part sooner or later wears out and fails);
- mechanical impacts leading to damage and deformation;
- operating the engine in violation of the manufacturer's requirements and recommendations.
Breakdown can be caused, among other things, by the use of low-quality coolant, mixing antifreeze with other types of antifreeze, and the use of all kinds of sealants that can clog the pipes and affect the circulation of the coolant (coolant). At the same time, the human factor cannot be ignored when, due to incompetence in matters of radiator maintenance and repair, a part has to be replaced.
Often, simple dirt and poplar fluff that clog the plates can cause the engine to heat up. Due to systematic overheating, the fuel in the cylinders begins to detonate due to the increased temperature of the coolant. As a result, the cylinder head burns out, the block itself becomes deformed from high temperatures, and cracks appear. And ultimately, the destruction of the piston group and crank mechanism completes the picture. It's not far from a major, expensive engine overhaul.
You need to carefully monitor the condition of the cooling system and the radiator in particular.
Signs of trouble
Even a beginner can determine that there are some problems with the radiator. This does not require special knowledge. It is enough to understand in general terms the principle of operation of the cooling system of the Lada Priora.
Troubleshooting
What are they related to?
Low coolant levels will also lead to rapid overheating. It is easy to find a leak by characteristic smudges on the surface, as well as by the presence of antifreeze or antifreeze where the car is parked.

Replacing a Priora Cooling Radiator with Panasonic Air Conditioning
Lada Priora radiator cooling system is being changed
When to change
On a Lio Priora, the radiator must be replaced if an antifreeze leak is detected. The general symptoms of this are: lack of engine cooling, coolant is rapidly decreasing, no traces of antifreeze are observed.
Please note that if you find a breakdown, then during self-repair you will need to replace the radiator, since repairs can only be carried out in specialized workshops with special equipment.
It is also not recommended to use sealants or similar products to seal leaks on Prior. When used, the cooling elements become clogged and future repairs will be more expensive.

(Lusar).
. then disconnect the expansion hose fastener from the front panel.
Note. To repair the radiator yourself, rinse it thoroughly and check for cracks in the plastic elements. If they do, it won't work. If not, connect the pipes and lower them into the water. Blow air to find the leak.
Also, of course, before attaching the hoses, apply a thin layer of sealant to prevent further leakage.
Features of replacing the radiator on a Lada Priore with air conditioning.
They installed 3 types of radiators on Priora: prefabricated alloy, for cars without climate control (software) and 5 types soldered for Hala and Panasonic air conditioners.
The heat losses of soldering radiators on a Lada Priora with air conditioning are 1.5 times greater. First, the condenser is cooled, which is placed in front of the radiator to cool the engine. Therefore, installing the wrong type of product will of course perform additional tasks to overheat the engine. It is also worth noting that the lack of cooling may be due to poor pump performance.
How does the radiator in Priora work and what functions does it perform?
As stated above, in Lada Priora and other domestic and foreign cars the cooling radiator optimizes the temperature of the liquid. Note that the radiator does not have any effect on the cooling system when the so-called cold engine is started. It does not start working at all until the car engine is sufficiently warmed up.
When the temperature reaches a certain point, in particular on the domestic Lada Priora this figure is 85-90 degrees, the thermostat opens and the filled antifreeze circulates through the cooling system. When the “engine” operates at high speeds, in particular, when the car is moving at low speed, and the cooling radiator is unable to cope with its task, and the temperature of the power plant begins to rise again, and then the fan turns on, which forcibly cools the antifreeze, located in the radiator at this moment.
The basic radiator on LADA Priora is made of parts made of brass. This material has high thermal conductivity. The core of the device and its middle part are a kind of plastic structure through which special tubes pass, which are connected to the plates by soldering. The coolant passing through the core of the device is distributed into several streams that run separately. This system allows antifreeze to be cooled much more efficiently.
The radiator tanks are connected to the system by pipes made of rubber. The lower reservoir is equipped with a tap, which makes it easier to drain old antifreeze during replacement. There is also a special tap on the cylinder block. From here the coolant can be drained from the water jacket of the power unit. In general, the design of the heat exchanger is quite simple, but very effective.
