Replacing the heater radiator Lada 2108 (VAZ 2108) with your own hands

Design and purpose of the heating system

The design of the VAZ 2108 stove and the principle of its operation are quite simple. The heated coolant enters the heater radiator located under the dashboard. In order for the liquid to circulate between the heater radiator and the cooling system, rubber pipes are installed, secured with metal clamps for a tight connection.

In the interior of the VAZ 2108, there are several holes for the release of warm air. Since the radiator is located in the center of the dashboard, and the holes are also located at the edges, a special heater motor is used for uniform air circulation. It has a built-in fan that circulates warm air throughout the cabin, ensuring rapid heating.

The stove motor is considered one of the most important parts of the entire system. The scheme of its work includes:

additional resistor;
electric motor rotating the fan;
switch for the current operating mode.

All these systems, when assembled, provide uniform heating of the interior of the VAZ 2108 car.

Replacing the tap in the heater of a VAZ 2109 cannot always solve the problem of heating the interior, like its brothers - models 2108 and 21099. The system responsible for heat in these cars has many similarities, so let’s look at the problems and troubleshooting using their example.

What is hidden under the panel in the car interior?

The “refrigerator effect” becomes most noticeable if you still continue to use old VAZ models with front-wheel drive: 2108, 2109, 21099. Let's try to figure out whether there is any possibility of replacing the heating system yourself. Despite the visual identity of the car models, there is still some difference in these VAZ units of the 8th and 9th models.

The interior is heated by air, a radiator connected to the engine cooling system is responsible for heating it, and the heater itself is located under the instrument panel in the car, which is higher in the VAZ 21099 due to some design features of the stove.

With the help of connected air ducts, heat flows into the interior.

Radiator in the engine cooling system

To force heated air into the cabin, a fan is located at the top of the heater, which rotates using an electric motor. The easiest way to access it is from the engine compartment.

The heater radiator, mentioned above, is located in the VAZ 2109, 2108 and 21099 models near the heater itself.

It has a seal in the form of a polyurethane foam gasket and consists of two plastic tanks, cooling plates and tubes arranged in two rows.

Since heating is connected to the car’s cooling system, fluid circulation through the radiator occurs using the pump of this system.

You can regulate its flow using the heater tap and various levers that affect the position of valves and dampers.

Warm air enters the cabin through two central and two side nozzles, inside of which there are dampers that regulate the intensity of heating. The direction of flow is also changed by blades-blinds using levers in the cabin.

After the air in the cabin is heated, it is necessary to circulate it and maintain the set temperature. It is necessary to release the waste stream outside.

Dismantling process

After draining the antifreeze, you can begin replacing the radiator itself.
Remove the screws that hold the front panel in place.
Unscrew the fasteners located on the rear wall of the glove compartment.
You also need to remove the screw, which you will find near the side mirror on the passenger side.
Once these fasteners are removed, the front panel will move freely up and down on the passenger side.
To make your work easier, lift the panel as high as possible and insert something like a wooden block into the resulting gap. Usually you need a stopper about 7 centimeters thick.
Lie on your back on the floor on the passenger side, unscrew the three fasteners that hold the heater in place. Get her out. The radiator has been removed.
Apply a rubber seal to the new unit and insert the device in place of the old radiator. Don’t forget to clean the unit’s landing site first.
Reassemble the unit.
Fill the system with old or new coolant. This is an excellent reason to change the antifreeze if the old one has been in use for a long time.

Antifreeze should be added sequentially. First add fluid to the reservoir up to the MAX mark. After this, you need to start the engine so that it runs for about 15 minutes. The antifreeze level will drop, and you can add the missing amount.

The work is completed. The old radiator is recycled, the interior is tidied up and you can enjoy the result.

Removing and replacing the heater radiator on VAZ 2108, 2109, 21099

Hello, from this article you will learn the reasons for the failure of the heater radiator and how to replace the heater radiator on a VAZ 2108, 2109, 21099 yourself. The heater radiator, like the cooling radiator, has its own service life and cannot last forever. Firstly, it can become clogged with various dirt or rust, this happens especially quickly if you do not change the coolant in the cooling system for a very long time. Secondly, due to age or poor quality material from which the radiator is made, it may leak. You can notice this by the smell of antifreeze or antifreeze in the cabin and a puddle of coolant in the passenger’s feet. There is no point in welding or somehow repairing the stove radiator; it is not expensive, so it is better to immediately replace it with a new one, especially since the new stove radiator should have excellent heat dissipation and the car, especially in winter, will become even warmer than earlier. Before you start removing the heater radiator itself, you need to drain the coolant from the system; by the way, you can change it at the same time, then there will be even more heat in the car. The heater radiator is located on the left at the passenger's feet. We unscrew the bolts on the hose clamps and disconnect them from the radiator (be careful, most likely all the coolant has not drained and it will flow from the hoses, so prepare rags or some kind of container in advance

After this, you need to unscrew the three screws that secure the heater radiator to the heater body

Then all that remains is to pull out the heater radiator, but the cable for adjusting the windshield defroster gets in the way, so we just unscrew its fastening, move it a little to the side and remove the heater radiator from the housing

Installation of a new heater radiator is carried out in the reverse order of removal. We also pour coolant into the system and check how the new radiator heats. At first there may be no heat, this means that there is air in the system; you just need to drive the car to warm up the engine to operating temperature, or you can unscrew the cap of the expansion tank and compress the cooling system pipes. This method also helps: you can stand on a hill so that the front of the car is looking up and accelerate.

You can also watch a video about replacing the heater radiator on a VAZ 2108, 2109, 21099:

How to change the heater radiator on a VAZ 2109

Most often, when there are problems with the heater core, we are talking about detecting a leak. This situation implies replacement of the unit.

How to change the heater radiator on a VAZ 2109

Most often, when there are problems with the heater core, we are talking about detecting a leak. This situation implies replacement of the unit.

Troubleshooting

To find the source of a leak in the heater radiator, pay attention to the following points:

The primary sign of a leak in the interior heating system is an increased frequency of adding antifreeze to the expansion tank. At the same time, it is impossible to guarantee that the problem is in the radiator itself;
Examine the condition of the heater valve and pipes;
If the culprit is a faucet, it is not difficult to determine . If there are no unpleasant sweetish odors inside the cabin and the floor is not covered with traces of coolant, then this is definitely not it. The presence of such signs indicates that the stove tap needs to be replaced;
The presence of deformations and cracks in the pipes can only be determined by visual inspection. Therefore, dismantling work will have to be carried out;
Having discarded the options with pipes and tap , there is only one option left - damage to the heater radiator itself.

You should not delay repairing the radiator, since this will first lead to the need to spend extra money on antifreeze (moreover, you yourself will breathe in the antifreeze vapors, which can lead to poisoning). A liter of coolant costs about 100 rubles. And over time, the problem will worsen, antifreeze will fill the interior, begin to corrode the floor covering, and cause a lot of other troubles.

Which radiator to buy

When choosing a new radiator for the stove of your VAZ 2109, you should understand what exactly you want to achieve and what budget you have.

Today, consumers are offered two types of radiators to choose from:

Radiator type	Peculiarities
Aluminum	A relatively inexpensive radiator option, which is characterized by high thermal conductivity. However, such a device cannot be repaired, which is its main drawback. But in practice, repairs are not carried out so often, so few people pay attention to this disadvantage
Copper	If necessary and a leak is detected, the copper radiator can be repaired - soldered. Thermal conductivity indicators are slightly higher when compared with aluminum analogues. But at the same time, the price is quite high - both for repairs and for the radiator itself.

Due to unprofitability and high cost, most VAZ 2109 owners choose aluminum radiators. But it all depends on your personal decisions and preferences. When actively using a car in harsh winter conditions, a copper radiator is fully justified.

Replacement

Before you begin replacing the device, be sure to evaluate the condition of the new unit.

Replacing the heater core can be done using two methods:

With the removal of the instrument panel , removing the panel, the work is easy and quite convenient. But you will have to spend at least 6-8 hours on this, depending on your level of preparation.
Without removing the dashboard . The second method does not require removing the panel, which makes the procedure more complicated. But it literally takes 2-3 hours to work.

Most car owners want to do everything quickly, but efficiently. The process of dismantling the panel takes a lot of time and requires careful fiddling with each fastener. Therefore, the best option for most is without removing the dashboard.

To work you will need:

Ratchet;
Set of heads;
Set of screwdrivers (flat and Phillips);
Container for draining antifreeze with a volume of 8-10 liters;
Rubber gloves for protection;
Spanners;
Garage with a pit.

When everything is ready and you are ready to work, you can start:

Get into the hole under the car, having previously turned on the handbrake, placing supports under the wheels and removing the negative terminal from the battery. All in the name of safety.
Drain the coolant from the radiator by unscrewing the drain plug.
Next, after draining the antifreeze from the radiator, you will fill the container with approximately 2 liters. Let's move on to the drain plug on the engine. Antifreeze is drained in the same way as from a radiator. A hose with a diameter of 1 cm and a length of about 1 meter can help. All work on draining the coolant must be performed with the engine cooled down and wearing gloves.
The plug for draining coolant from the engine is unscrewed with a 17 key.
Loosen the pipe clamps and drain the remaining antifreeze from the stove system. Here you will have to lie down in the cabin with your head towards the engine, since the pipes can only be reached from the passenger side.

Radiator Maintenance

Clean the outside of the radiator of dirt, leaves and other debris. Inspect it carefully for any coolant leaks. If you find any leaks, it is advisable to replace it. If everything is fine, rinse it with a descaling agent (available at any hardware or auto store). If such a remedy is not available, use whey or a weak solution (3 - 5%) of sulfuric or hydrochloric acid. Pour the product into the radiator until it is completely filled. Perform this work wearing rubber gloves and safety glasses.

Remember that the chemical reaction will cause the product to bubble a lot, so work carefully. Cleaning time using whey 20 – 40 hours

Cleaning time using ready-made descaling agents or acid solutions is 5 – 10 minutes. After which the liquid must be poured out and the radiator thoroughly rinsed with clean water.

Step-by-step process for replacing a stove radiator

So, how to replace a radiator using the example of a VAZ-2109? The work can be carried out using two methods – with removal of the dashboard and without dismantling the device.

The first option involves an easier process that will take about 6 hours. In the second, everything will be somewhat more complicated, but the time spent will not exceed two hours. It's quick or easy - it's up to you. We will tell you how to replace it without disassembling the car dashboard.

To get started, prepare the following tools:

two screwdrivers - cross and flat;
ratchet with a set of heads;
any container with a volume of up to 8 liters so that the coolant can be drained;
rubber gloves to avoid chemical burns;
spanners.

It is recommended to carry out work in a garage with an inspection pit.

After everything is prepared, you can begin replacing the heater radiator on a VAZ-2109 car. Following our recommendations, the process will not seem so difficult.

Let's start:

Put on gloves and climb into the inspection hole. Unscrew the radiator cap and drain the liquid into a container. To simplify the process, take a hose 1 m long and 1 cm in diameter.
After all the liquid has been drained, it should be about two liters by eye, it is necessary to drain the coolant from the engine cooling system. To do this, just find the appropriate plug on the engine and do everything in the same way as with the radiator. The button is unscrewed using a key with a diameter of 17 mm.
At the next step, the pipes of the clamps are lowered and the remaining antifreeze is drained from the heating system. To do this, you need to get to these nodes from the salon and carry out this procedure. It's easier to do this from the front passenger seat.
After draining all the antifreeze, proceed to dismantling the radiator. First, remove the screws that hold the front panel in place.
The next step is to remove the screw on the back wall of the glove compartment and the screw located next to the passenger side rear view mirror.
Once all the screws are removed, the front panel should move up/down freely. To simplify the work, lift it up to the maximum and place a 7 cm block under it.
Place your back on the passenger seat mat and unscrew the 3 screws that hold the heater in place and remove it.
At this stage, cover the new radiator with rubber band and put it in place. Be sure to clean this area before installation.
Final step: Reassemble the entire system in reverse order. This should no longer cause additional difficulties.

How to remove the radiator for 2108 – 21099 and 2113 – 2115

Cars of the Samara 2 family - VAZ 2113 - 2115 are copies of the Samara 1 family that have been restyled. Therefore, the technology for replacing the radiator for these machines is the same. To remove the heater radiator, you will need:

plumbing hose from the mixer;
basin;
small containers to place under the radiator;
a set of keys;
normal-sized flathead and Phillips screwdrivers;
wooden block 5 - 7 cm wide;
flat and Phillips screwdrivers with short blade.

Access to the heater radiator of these cars is from the passenger compartment, from the passenger seat. Therefore, first of all, remove the front passenger seat, this will free up space for work and save you from having to work in very cramped conditions. Then disconnect the battery. This procedure is required because part of the electrical wiring runs next to the radiator. Then place a basin for coolant on the ground under the engine and use the handle on the instrument panel to open the heater tap (turn the handle to maximum heating mode). There are two options for draining the liquid. In the first option, the drain plug on the cylinder block is unscrewed and the liquid pours down somewhere, flooding the engine protection and splashing the engine compartment. In the second option, a plumbing hose from the mixer is quickly screwed into place of the drain plug. Its thread matches the thread of the drain plug, so this operation does not cause any difficulties. The hose is passed through the holes in the engine protection and directed into the basin.

Despite some differences in the dashboard of different models, most of the subsequent steps are performed in the same way, with all differences indicated. First of all, you need to unscrew the screws on the console trim. Then pull out and disconnect the radio, remove its mounting socket and unscrew the screw that secures the panel. It is also necessary to remove all stove control knobs. To do this, you need to insert a long thin screwdriver under them, this will help to separate the handle latch and the lever. On cars of the Samara 1 family (2108 - 21099), it is necessary to remove the heated glass deflector grille on the right side and unscrew the self-tapping screw securing the panel to the body. On the right side of the panel (torpedo), you need to unscrew two screws (on some models, self-tapping screws are installed instead of screws) securing the panel to the body.

Having completed all this, pull the right edge of the panel towards you, moving it 5 - 7 cm and place a block to fix the torpedo. Now you can start removing the radiator. It is located next to the right side of the body just below the instrument panel. You can identify the radiator by the rubber hoses that fit to it. Place a small container under the radiator to prevent coolant from spilling onto the floor. Using a small screwdriver, unscrew the clamps and remove the rubber hoses from the radiator tubes. Unscrew the two screws that secure the radiator and remove it out.

Replacing the Radiator Heater VAZ 2108 Low Panel

If during a routine inspection of a tank with coolant VAZ 2108 2109 21099 you saw that it became smaller, increased to its usual level, and after a few days the level dropped again. This means that there are some leaks in the cooling system. It is sought through a visual inspection: the attachment points of the hoses, clamps, and the absence of cracks in the hoses are checked. If during the inspection you find that coolant is entering the passenger compartment, this indicates that VAZ 2108 2109 21099 is leaking from the heater radiator. With this malfunction, you begin to drip antifreeze onto the accelerator pedal and connect with it on the driver’s shoes. Antifreeze. corrosive liquid, so you can ruin good shoes. In addition, the antifreeze itself costs money; a liter tube of antifreeze costs about 5. Therefore, since antifreeze begins to leak from the radiators of the VAZ 2109, you need to look for this leak and fix it. What do you need: a replacement heating radiator (stove) for a VAZ 2109 . But it is not easy to approach him. Our client is still in control of the vehicle, saying he needs to disassemble the entire front panel. Of course, without this it will be even more convenient to change the radiator, but it will take you about 3 hours, we are not talking about reassembly. Therefore, the method for replacing the VAZ 2108 2109 21099 heater radiator without removing the front panel is given below. But first you need to drain all the antifreeze from the engine cooling system. Only a VAZ 2109 filled into the cooling system circulates about 8 liters. antifreeze, so prepare tanks where you will pour it in advance. Wear rubber gloves because it is best not to touch antifreeze with bare hands. It will also be useful to have a couple of liters. , because perhaps a little, however, it will shed. Open the coolant reservoir cap and find the cap at the bottom of the radiator.

Prepare a hose about a meter long and a centimeter across. Insert one end into antifreeze. Remove the radiator cap and push the 2 ends of the hose to the radiator outlet. In a VAZ 2108 2109, the radiator 21099 usually holds about 2 liters. antifreeze. When the antifreeze does not leak out, unscrew the plug. Now you need to drain the antifreeze from the small cooling circuit. The engine has a special limiter for discharging antifreeze. This is the vehicle's lowest cooling point.

Drain plug VAZ 2109 for the cooling system

Prepare several plastic bottles (preferably 5 liters), cut off their necks to make it easier to drain the antifreeze. Open the heater mixer in the cab (closed in the picture) to allow all the antifreeze to flow out of the radiator.

Open the VAZ 2109 heated radiator mixer

Unscrew the plug with a 17 key and again press the hose to the drain hole in the engine. Waiting for all the antifreeze to come into contact with the small cooling circuit. Then insert the plug into the area.

Now you need to remove and loosen the clamps on the heater radiator. Unless, of course, you are a very thin person, remove the passenger seat. There will be more than just maneuvers. If you don't want to take photos, move them as far back as possible. We rise to the place where the heater radiator is attached to the hoses of the heating metering system.

What is hidden under the panel in the car interior?

This difference is not fundamental. It’s just that in the process of evolution, unnecessary air ducts were removed from the design, the shape of the damper and the location of the radiator were changed. But this does not change the principle of operation. The interior is heated by air, a radiator connected to the engine cooling system is responsible for heating it, and the heater itself is located under the instrument panel in the car, which is higher in the VAZ 21099 due to some design features of the stove. With the help of connected air ducts, heat flows into the interior.

Radiator in the engine cooling system

To force heated air into the cabin, a fan is located at the top of the heater, which rotates using an electric motor. The easiest way to access it is from the engine compartment. The heater radiator, mentioned above, is located in the VAZ 2109, 2108 and 21099 models near the heater itself. It has a seal in the form of a polyurethane foam gasket and consists of two plastic tanks, cooling plates and tubes arranged in two rows.

Since heating is connected to the car’s cooling system, fluid circulation through the radiator occurs using the pump of this system. You can regulate its flow using the heater tap and various levers that affect the position of valves and dampers. Warm air enters the cabin through two central and two side nozzles, inside of which there are dampers that regulate the intensity of heating. The direction of flow is also changed by blades-blinds using levers in the cabin.

After the air in the cabin is heated, it is necessary to circulate it and maintain the set temperature. It is necessary to release the waste stream outside. In this regard, on VAZ 2108 models, hot air flows out through holes located in the central body pillars. On 9-model cars, these holes are located in the corners of the rear side windows and have rubber valves that prevent atmospheric air from entering the air ducts.

Troubleshooting

To find the source of a leak in a stove radiator, pay attention to the following points:

The primary sign of a leak in the interior heating system is an increased frequency of adding antifreeze to the expansion tank. At the same time, it is impossible to guarantee that the problem is in the radiator itself;
Examine the condition of the heater valve and pipes;
If the culprit is a faucet, it is not difficult to determine. If there are no unpleasant sweetish odors inside the cabin and the floor is not covered with traces of coolant, then this is definitely not it. The presence of such signs indicates that the stove tap needs to be replaced;
The presence of deformations and cracks in the pipes can only be determined by visual inspection. Therefore, dismantling work will have to be carried out;
Having discarded the options with pipes and tap, there is only one option left - damage to the heater radiator itself.

You should not delay repairing the radiator, as this will first lead to the need to spend extra money on antifreeze. A liter of coolant costs about 100 rubles. And over time, the problem will worsen, antifreeze will fill the interior, begin to corrode the floor covering, and cause a lot of other troubles.

Progress

Remove the lower console, which goes from the interior heating control levers to the gearbox housing.
Move both front seats as far back as possible. If, in addition to the heater radiator, you also want to replace the faucet, then you will need to remove the plastic trim from the thresholds and lift up the carpet.
File the magazine shelf under the glove compartment on one side; you can screw it back using self-tapping screws.
After which you will see that you can easily remove the part into the resulting gap without any problems.
Turn off the heater tap and prepare plugs that you will use as plugs and a container for the remaining coolant to prevent the remaining antifreeze that has accumulated in the radiator itself from spilling.
Unscrew three bolts on each side of the radiator.
Loosen only those clamps that fit directly to the radiator, but do not tighten them.
Now the hardest part is that you need to drain the remaining antifreeze from the radiator. To prevent coolant from spilling on the floor, place waterproof mats or an old cloth under the faucet, at the front passenger's feet, and under the radiator.
Pull off the pipes from the radiator, the first one to remove is the bottom one, which is located below on the tap; it is closed. Place a container and drain the coolant from the radiator. Keep the cork ready. About a liter of liquid may leak out. You may need to drain the liquid several times, so you will most likely have to plug the pipe with a plug.
Remove the outlet pipe from the radiator, but do not lower it down, as coolant may pour out of it, keep it at the level of the attachment to the radiator. There is no need to drain the liquid, just plug the pipe with a plug.
Now you can pull out the radiator itself.
Replace it with a new one.
Plug in the top outlet pipe.
Then the bottom one.
Tighten the clamps.
If necessary, remove the air lock.

Dismantling the heater radiator on a VAZ 2110 – 2112

To remove the radiator, you will need the same tools as described in the previous section. During the preparatory steps, disconnect the battery and drain the coolant (the technology is the same as described above), then remove the frill and wipers. These operations are described in detail in the article repairing the windshield wiper trapezoid on a VAZ 2110. The radiator is located immediately behind the vacuum brake booster (VUT). To get to it, you need to remove the VUT. To do this, unscrew the two nuts securing the brake master cylinder (MBC) from the VUT and move the cylinder to the side. Then, from the passenger compartment (you may need to remove the driver's seat), unscrew the 4 nuts securing the brake pedal and pull out the VUT assembly with the pedal through the hood. Access to the heater radiator is open; it is located to the left of the place where the VUT stood. You can identify it by the rubber hoses that go with it. Unscrew the clamps and remove the hoses. Then unscrew the three fastening screws and pull the radiator to the right, remove it from the stove.

The stove doesn't heat well

If the stove does not heat well, and this can be due to several reasons.

This mainly happens due to the fact that the heater radiator itself is clogged, the method for flushing the radiator is as follows, the first method is to disconnect the heater hoses in the engine compartment and connect one of the hoses to the hose from the water supply, open the water as loudly as possible and let it flow through the heater radiator for a minute , then change the direction of water flow, connecting it to the other end of the radiator stove, and also let the water flow for about a minute.

The second method, swap the hoses connecting to the heater radiator so that the coolant begins to circulate in a different direction, also helps a lot, and the heater begins to heat well.

What is needed and when is it necessary to replace the radiator?

Repair and replacement of the VAZ 2109 heater radiator is required if:

The radiator is leaking, there is a smell of coolant in the cabin, stains, drips from it;
the radiator grille is clogged with dust, leaves, insects, as a result, air does not pass through it, and it is impossible to clean them;
scale, corrosion of the walls of radiator tubes, aluminum radiators are especially susceptible to this;
powder sealant, if used, may clog the system by getting into the coolant. In this case, thin radiator tubes are damaged and clogged faster than others.

Before replacing the heater radiator on a VAZ 2109, you need to check other elements of the system to see if there are any antifreeze leaks, cracks, or air pockets. But it is still recommended to change the pipes along with the radiator.

Tools, materials

Replacing the VAZ 2109 heater radiator requires a minimum of tools:

screwdrivers - Phillips, slotted, preferably a set;
wrenches and sockets, preferably in a set; if not available, you can get by with a socket head No. 10 and a deep socket, also 10;
ratchet handle, extension;
Rubber gloves, dishes for antifreeze, and the antifreeze itself are also desirable;
It’s most convenient if the car can be driven into a viewing hole.

Before replacing the heater radiator on a VAZ 2109, you need to select and purchase it. For the VAZ 2109, auto stores offer 3 types of radiators, these are:

Made from copper. Weighty, more expensive than standard ones (not much, the difference is about 700 rubles). They are distinguished by high reliability and long service life. Their main advantage is that they can be cleaned, restored, and if a leak is detected, such a radiator can simply be soldered. The only drawback is that it heats a little worse than aluminum, it warms up more slowly.
A standard VAZ aluminum radiator is sold complete with pipes and clamps, the cost of the entire set is around 1,000 rubles. It heats up quickly, transfers heat well, requires replacement in case of any malfunction, maintainability is zero.
Non-original radiators can cost up to 500 rubles; their low quality is not justified by the low price; in addition, due to less frequently placed plates, they heat worse.

After preparing all the tools, spare parts, materials, you can begin the repair.

Replacing the heater radiator on a VAZ 2109 with a high panel

1. The heater radiator is located at the feet of the front passenger, so it is better to remove the front passenger seat for work.

2. Find the bolts on the right side that secure the panel and unscrew them.

Location of the bolts that need to be unscrewed to replace the heater radiator on a VAZ 2108, 2109 or 21099

3. Pull the panel towards you slightly and insert a spacer into the resulting gap (a wooden block of the appropriate size will do).

When replacing the heater radiator on a VAZ 2109, you must be careful

4. Close the tap, place old rags in places where coolant leakage may occur.

5. Open the hood and the expansion tank cap on the radiator. To reduce the pressure in the system, close the lid.

The heater core is located in the area between the glove compartment and the lower shelf. Further actions must be performed very quickly

to prevent antifreeze from spilling. In addition, to plug the hoses coming from the radiator, you need two rubber plugs.

6. Prepare one rubber plug and insert your hands through the allocated panel to the radiator.

7. Remove the lower pipe and QUICKLY plug the hole with your left thumb, then insert the plug into the hose with your right hand.

8. Take a container prepared in advance for the coolant, place it under the pipe, remove your finger and drain the coolant.

9. Repeat this operation with the upper pipe.

10. When the coolant has been drained, you can remove the heater radiator and install a new one. When removing the heater core, you must first lift it up, move it slightly, and then pull it down.

The procedure for removing and installing the heater motor on a VAZ 2109-2108

First of all, you need to open the car hood and unscrew the 5 bolts securing the plastic trim, as shown in the photo:

And remove it so that it doesn’t get in the way in the future:

Now you need to remove the hood seal:

To then easily pull off the protective cover, under which the heater motor on the VAZ 2109-2108 is located:

After which access to the fan is open:

As you can see from the picture above, you need to unscrew the two mounting bolts that are located on the sides of the motor:

Well, then you will have to suffer a little. The fact is that on the VAZ 2109-2108 the power wires are soldered directly to the motor, and the terminals are connected to the electrical wiring inside the car. To put it mildly, the decision is simply idiotic. Now, in the cabin, by putting your hand under the panel on the driver’s side, we find the positive wire plug and disconnect it:

In the same area there is a negative wire, and there are even more problems with it, since it is secured with a nut, and in order to unscrew it, you must first feel it with your hand, and then use a socket and a ratchet to do this work. Immediately from the passenger compartment, you can insert these wires through the rubber seal in the hole in the body - it is visible in the top photo - from there two wires enter the passenger compartment.

And now, from the outside, turning the heater motor at different angles, we find the most convenient position, and remove it through the right side (in the direction of travel of the car):

And finally remove it from the engine compartment, as shown in the photo below:

If the part needs to be replaced, you need to buy a new stove fan, the price of which for a VAZ 2109-2108 is about 500 rubles for one motor. And if you buy it complete with the case, the price will be about 1000 rubles. We carry out the installation in reverse order.

Today, no car can do without a heater in the cabin. The VAZ 2108 is no exception. This model was equipped from the factory with a stove capable of heating the interior up to 25 degrees, with a “+” sign. This is a pretty good indicator, considering that the G8 began production back in 1971.

Replacing the heater radiator on a VAZ 2108, 2109 or 21099 with a low panel

In general terms, the procedure for replacing the heater radiator on a VAZ 2109 with a low panel is similar to those for a high panel. In this case, it should take a little less time, since you can change the heater radiator without removing the passenger seat

. In addition, experienced car owners advise removing the steering wheel cover so that it is not damaged when the panel is bent.

Please note that upon completion of work, be sure to remove the coolant from your hands, as it is hazardous to health!

Hands must be washed and dried!

Part selection

Before replacing, the first thing you need to do is select a radiator and buy it. Aluminum and copper radiators are available on the market today.

Aluminum has the following features:

low price;
high thermal conductivity;
In the event of a breakdown, repair is not possible.

Copper radiators are characterized as follows:

unlike aluminum analogues, the thermal conductivity is higher;
If there is a leak, you can always solder the part;
the cost is slightly higher than that of aluminum analogues;
The price of repairs is also not cheap.

The high price of copper radiators, as well as low demand, makes copper radiators a rare item that cannot always be found in stores (a small number of manufacturers produce them).

Which one to choose is up to you. In this article you will learn only food for thought, on the basis of which you can make an informed choice. The main thing worth noting is do not buy painted radiators.

How to change the stove on a VAZ-21099? Features of device dismantling

Before removing the heater from the car, for example, in order to clean it, repair it or change the body of the VAZ-21099 heater, you need to let the car engine cool completely. This will save you from unintentional scalding with hot antifreeze.

Next, you need to determine the type of panel installed in the machine. There are two of them:

low;
high.

As a rule, on a high dashboard, the niche for installing the radio is located in the same plane as the instrument panel, and on a low one, it is located just under the controls.

Basic faults

Sometimes, there are cases when the heater motor fails. In order to determine that it is the motor that is broken, it is enough to know a number of characteristic symptoms of motor failure.

The first sign of a malfunction is that the motor that activates the fan stops working when switching from one mode to another. Usually, the cause of such a breakdown lies in the additional resistor. Since this part cannot be repaired, it just needs to be replaced with a new one.

The second sign is that when the electric motor is turned on, the corresponding fuse blows. In this case, you need to check the winding of the armature located on the ground. It often happens that it simply closes.

The third symptom is that the fan rotates slowly, regardless of the mode in which the stove motor operates. This, as practice shows, is a consequence of contamination, or worse, oxidation of the collector. To eliminate this malfunction, the collector must be thoroughly cleaned. If this procedure does not produce results and the fan still rotates slowly, then try replacing the bearings. They have probably reached a critical stage of wear and tear and are moving with great difficulty. Less commonly, the cause may be an interturn short circuit inside the armature winding. If the motor of the VAZ 2108 stove does not turn on at all and does not rotate the fan, then the reason is not in the design of the motor, but in a break in the circuit itself. To make sure of this, use a voltmeter and carry out diagnostics.

Maybe it's better to put cardboard in front of the radiator. In this case, changes in engine settings can be carried out by replacing the heater radiator VAZ 2108 low panel with a slight increase in the basic parameters, for example, for permanent use, so based on individual wishes when upgrading the car into a racing or similar car. And everything is very simple, there is nothing superfluous in it, and then through it it goes into the engine to the water pump. We feel to see if there is any tangible step in this place.

Its burnout may be due to the replacement of the alternator belt a day ago. A new brush is inserted, and it must pass through all points, just like the old design on recently produced machines.

If, while working at a tire shop, you forgot to tighten the nuts, but there are too few, I would like more, and with some pictures. We check the functionality of everything installed. Having done this, you can determine for yourself the frequency of oil changes in Kalina Cross. If there is wear, the bearings or generator covers must be replaced. Now we take the lubricant and apply it in a fairly generous amount to the inside of the hub. The fluid level has dropped slightly, so those who have these devices are proud of them and use them. After adding more brake fluid, welders and turners will provide all possible assistance to make your dream a reality. How does your genes get excited? As a result, during disassembly I saw an impeller that had fallen in half.

When you hit a police officer, if you don’t calculate it well, it hits the body hard, the same way when a wheel falls into a hole. It was able to fully meet the requirements of the road surface in Russia and was highly convenient for active users. Please note, move the exhaust to the side and thereby free up space under the trunk floor. Sand will not get into it; unscrew the bolt securing the strut to the rear beam from below.

The main thing is that they are in good working order and ready to work. When pulling out, the pump should be turned clockwise and tilted slightly so as not to accidentally damage the float part of the fuel sensor. Although very rarely, except from garage to garage. As for the connectors used, we need an eight-pin type mother, I found some in the garage, installed it, connected it, but it didn’t have enough strength. There is a plate on the right, I put it on the alarm and go home to sleep. I won’t describe here what and how, so as not to deviate from the main topic, if anyone is interested. This is such a drovalt, I drove it.

Features of replacing a radiator on various car models

When reinstalling the radiator, the following questions may arise:

Replacing the heater radiator on a VAZ 21099 with a high panel

If the radiator needs to be replaced, the high panel does not need to be removed. You will need to remove all the screws that secure the panel to the car body. Then the steering casing is removed and the right side of the panel is moved into the cabin.

Important! Before moving the panel to the side, you need to disconnect the ignition switch wires and the alarm system from it.

Replacing the radiator of a VAZ 21099 stove with a low panel

If the front panel is low, in order to replace the radiator, it must be completely removed. Then follow the previously described sequence of actions.

Replacing the radiator of a VAZ 21099 stove with a high panel without removing it

If you don’t want to remove the panel every time you replace the radiator, you can file it down and then reinforce it with self-tapping screws. In the future, they are unscrewed if necessary. When replacing the radiator on an injection VAZ 21099, you should be attentive to the relays located under the panel.

After replacing the radiator, it is important to check how the stove works. Those who have done all these simple manipulations, the next time problems arise with heating the car, will not have the question of how to independently change the heater radiator on a VAZ 21099. Everything is simple if you do everything correctly. The radiator service life is approximately 8 years. If used incorrectly, it will fail within 2–3 years. For preventive purposes, the radiator should be removed for cleaning twice a year. And then reliable heat is provided.
