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.
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.
The procedure is as follows:
- 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.
Replacing the heater radiator on a Priora with air conditioning
After some time, the manufacturer began to equip its cars with air conditioning (climate control), for example, HALLA or Panasonic (article: 21703-8101012). The design of the new Priora heater from a maintenance point of view turned out to be much more convenient. Now, to replace the stove, you do not need to dismantle the frill, windshield wipers, heater or vacuum brake booster.
It is only necessary to: remove the sound insulation of the engine shield, remove the engine air filter hose and the seal in the area of the heater radiator hoses. All! Drain the antifreeze and remove the radiator towards you, towards the engine.
Video instructions are attached:
Thus, replacing the radiator of a Priora stove depends not only on the type of heater, but also on the chosen method of replacing it. How did you remove the heater radiator on your car? Which method suits you best? Let us remind you that solutions to other problems with the stove can be found in this article.

A customer arrived with a complaint about leaking antifreeze. He told me that somewhere along the way, they changed the pipes going to the heater radiator, but nothing changed. Since antifreeze flows down the engine shield, it is either the return pipe or the heater radiator itself. In our case, the heater radiator leaked.

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.
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.
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.
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.
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.
Replacing the radiator of the Priora stove
To work, you will need a standard set of tools, which includes socket wrenches 10 and 13, side cutters, a Phillips screwdriver, and a wrench 8. In both cases, you will have to disconnect the heating system hoses; the remaining coolant will pour out of them, so immediately place containers under the pipes heater Then the liquid can be returned to the system.
With air conditioning
- First of all, we need to remove the rubber seal of the windshield to gain access to the parts;
As you can see, dismantling the radiator in a Priora with air conditioning does not require draining the antifreeze. Coolant will only come out of the expansion tank and the heat exchanger itself. Removing the radiator in a VAZ 2170 with Panasonic air conditioning follows the same scheme, only a few fasteners may differ. Now you can replace your worn-out heater with a new one!
Without air conditioning
- Work begins by disconnecting the negative terminal of the battery. We remove the windshield trim along with the windshield wiper arms, as these elements will interfere with operation;
- The next step is to remove the coolant supply pipes to the engine injectors;
- The windshield trim is held in place by seven screws. Unscrew it to completely remove the element;
- Now we move on to the hood seal, in its center you will find a tightening screw - unscrew it;
- The engine noise insulation closes the passage to the heater system - pry up the plugs with a flat screwdriver and unscrew the plugs;
- We unscrew the screws and dismantle the sound insulation. Remove both covers;
Clean the heat exchanger and inspect it for damage. If cracks are found on the plastic elements, then you will no longer be able to repair the part - only replacing the stove radiator on a Priora, which is done in the reverse order, will help here.

Enter the text of the comment: the climate control does not work, not old, not new, the heater damper opens and closes all the way to the MMR, I change it every year in the spring, the damper does not close, I have to remove the MMR in the fall, everything is new on the computer, the regulator works
I unscrewed the 4 screws that hold the plastic plate near the heater radiator pipes, but for some reason it does not come out of the heater. Priora with Panasonic. I would be grateful if you could tell me.
You definitely won’t be able to repair the radiator yourself, as this requires special tools and skills. However, you can definitely remove and install a new one. Our instructions will help you achieve your goal. By following consistency in work, you can easily dismantle and replace the radiator.
How to replace a Priora radiator
First you need to prepare the following tools:
- head for key 10;
- Phillips screwdriver;
- pliers;
- container for liquid.
Next you need to proceed according to this scheme:
- First you need to drain the antifreeze into a prepared container. To do this, open the expansion tank and unscrew the plug.
- The fan shroud is then removed to disconnect the wires.
- The signal is removed.
- Then you need to loosen the clamps and disconnect the compression and outlet pipes.
- Unscrew the radiator mount to the body.
- Disconnect the fastening element.
- Loosen the tie clamp and remove it.
- Pull out the radiator and mounting bushings.
After this, it must be inspected for cracks and deformations in order to understand why it has ceased to function properly. Replacing the radiator follows the same procedure. You can purchase a new heater radiator at a specialized store. There are a large number of companies producing such devices, so you should trust proven ones.
For example, high-quality devices are produced by Halla and Panasonic. You must understand that without air conditioning, the car engine will overheat and eventually burn out. Replacing a motor is very expensive, so you shouldn’t allow such breakdowns. The radiator on a car with air conditioning must always work smoothly to avoid serious problems. Also, be sure to purchase high-quality grilles for this appliance.
If you understand your iron horse, try installing a new radiator yourself. But it’s better, of course, to ask for help from specialists who will do the job faster and better. Today, in every city there are service centers where craftsmen offer their services at affordable prices.
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.

Replacing the PRIOR radiator replacing the PRIOR radiator HOW TO REMOVE ENGINE COOLING RADIATOR ON PRIOR LUX HALLA
The radiator must be replaced if a coolant leak is detected from it. In a workshop that has special equipment, the VAZ 2170 radiator can be checked and repaired. You will need: a 10" wrench (a socket head is more convenient), a screwdriver with a Phillips blade, and pliers with long thin jaws.
1. Drain the coolant (see “Replacing the coolant”). 2. Remove the electric radiator fan for the Lada Priora (see “Removing and installing the electric radiator fan with casing”). 3. Remove the horn (see “Removing, installing and adjusting the horn”).
4. Loosen the clamp securing the supply hose to the radiator.
5. . and remove the hose from the radiator pipe of the VAZ 2172.
6. Similarly, disconnect the outlet hose from the radiator.
7. Unscrew the two nuts securing the radiator to the body of the VAZ 2171.
8. Remove the steam hose holder from the hole in the upper cross member of the engine compartment.
9. Tilt the radiator towards the engine. Loosen the strap clamp of the steam exhaust hose...
10. . and remove the hose from the VAZ 2170 radiator fitting.
Helpful advice Tape clamps for fastening hoses are inconvenient to use and are difficult to re-ensure the tightness of the connection. When disconnecting the hoses for the first time, we recommend replacing the band clamps with commercially available worm-type clamps.
11. Lift the radiator up.
12. Remove the two lower mounting cushions from the radiator if they remain on the radiator mounting pins or remove them from the holes in the cross member if they remain on the body of the VAZ 2171. Replace the torn or lost elastic cushions.
13. Remove the rubber-metal bushings from the radiator brackets. Replace torn or loose rubber bushings. 14. Rinse the outside of the radiator with a stream of water and dry. If there are cracks in the plastic radiator tanks, replace the Lada Priora radiator. 15. 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”).

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)!
