Why a copper radiator for the VAZ 2109 stove is an excellent choice

What aspects to pay attention to

In what cases does the heating system of a car interior fail? What aspects should you pay special attention to?

Insufficient opening of the heating tap

The real problem in most cases occurs in VAZ cars with front-wheel drive. To check, it is necessary to compare the temperature conditions of the two pipes, namely the inlet and outlet. If there is a difference in temperature, the valve is not open enough. In order to carry out the adjustment, it is necessary to tighten the cable designed to control the valve to the maximum open state. In this case, you should carefully monitor the condition of the entire structure, since the valve is a weak point and sooner or later its switching will no longer be possible. A drastic solution may be to remove the valve from the system or install a ball valve, but in both cases there will be a problem with the easy adjustment of the fluid used to cool the interior.

Insufficient tightness of air ducts

The air that is pumped by the fan of the stove used can partially escape into the cracks. At the same time, the temperature in the car interior decreases. It is imperative to seal the connections of the entire structure, since only in this case will the optimal air temperature be maintained.

Air pockets in the radiator

Another reason why the heating regulator cannot work at full capacity is the presence of air pockets. A manifestation of the problem may be cold air coming from the deflectors. In this case, the vehicle must be placed on a hill with its front wheels, then the heater tap must be fully opened and gassed.

In 99% of cases, the switch that controls the operation of the stove can be successfully adjusted

The most important thing is to understand what principles need to be followed and how you can increase the efficiency of heating equipment in a VAZ car

Antifreeze or antifreeze?

Of course, green or red antifreeze is much better than Soviet antifreeze, since it contains many additives that increase the service life of both the liquid itself and all elements with which it comes into contact. In particular, the pump is lubricated much better and its service life becomes longer. Antifreeze is also greasy to the touch, but cannot ensure maximum quality of operation of the mechanisms.

Heater radiators

Brand name – LRh – Luzar Radiator heater

Heating radiators (also known as heater radiators, also known as heater radiators) are heat exchangers that use the heat generated by the engine to heat the vehicle interior. They allow you to maintain a comfortable temperature and prevent the car windows from fogging up.

For reference: different names of this node have equal rights of use. For example, “heating radiator” and “stove” come from the function of this heat exchanger, “heater radiator” and “stove radiator” - from the installation location.

LUZAR manufactures hundreds of heater radiators for a wide range of cars presented on the Russian market. They can be purchased in partner stores throughout Russia or online.

Many models of heater radiators are supplied to car factories in Russia and Ukraine - both for passenger cars and for trucks and buses.

The production range of manufactured stoves is constantly increasing; New types are being developed for the most popular cars in Russia.

Powerful R&D allows us to conduct research in the field of improving heat exchangers and create new designs that provide increased performance properties of heater radiators. Main areas of research:

• use of different types of tubes
• changing the location of the tubes
• change in the “fillability” of the core
• use of turbulators-swirlers
• use of various aluminum alloys
• testing of solders with different characteristics
• improving the corrosion properties of metal
• ... and many other R&D areas.

Design of heating radiators from LUZAR

LUZAR heating radiators are available in three types:

1. Tubular-plate, prefabricated, aluminum. It consists of aluminum plates through which aluminum tubes pass, inside which coolant runs. The tanks on such radiators are made of plastic. Heater radiators of this type are used for heating small-sized salons due to limited heat transfer; have the best rigidity and light weight, as well as the lowest price.
2. Tubular-tape, non-assembled (brazed), aluminum. The corrugated aluminum tape in such a radiator is located between aluminum flat-oval tubes. Radiator tanks of this type can be made of either plastic or metal. The design of non-assembled (brazed) aluminum devices is the most universal, allowing the creation of heat exchangers with any specified characteristics. Aluminum stove radiators are lightweight and relatively high rigidity, as well as optimal prices.
3. Tubular-tape, non-assembled (soldered), copper-brass. The design is very close to type 2 - between the copper flat-oval tubes there are copper strips folded in the form of an “accordion”. At the same time, the tanks on such heating radiators are made of brass - in order to increase the overall rigidity of the structure. Copper heating radiators - due to the high specific heat capacity of copper - have excellent heat transfer rates. However, due to the high softness of copper, heating radiators made of this metal are forced to have a narrow tube and a large interval (step) between the tubes, which imposes serious limitations on maximum efficiency. Also, copper heater radiators have the highest cost and the lowest rigidity to torsion, fracture and internal pressure. In this regard, copper heater radiators are “outdated” and are gradually falling out of use.

LUZAR: TESTED BY TIME AND ROADS

LUZAR radiators have been awarded the “Radiator of the Year” award several times

How to choose a really excellent radiator for the VAZ 2109 stove.

When I went to an auto parts store, I found out that there are several types: factory aluminum, non-factory aluminum and copper.

After consulting with friends who have been driving for several years and have encountered such a problem, I learned:

• A copper radiator costs 2 times more than an aluminum one, but the heat is not very hot.
• A factory radiator costs around 1000 rubles and it’s worth taking this one, because... It is reliable and heats as expected. Its design is stronger than the original VAZ radiator and has swirlers that slow down the coolant, which contributes to more heating of the radiator. With such a radiator, you will begin to feel warmth in the car already at 60 degrees of the engine.
• A non-factory radiator costs 500 rubles, but it’s not worth buying. Firstly, it doesn’t heat up, and secondly, it can leak immediately after replacement. Thirdly, it doesn’t have swirlers, so the antifreeze flies through the radiator without having time to heat it up.

Having learned all this, I went to the store and bought an original DAAZ radiator, price 750 rubles. It looks like this:

Types of radiators

Radiators differ in case material, its quality and assembly method:

• Prefabricated . The very first and cheapest cooling elements that used a mechanical method, where the components were connected mechanically. No expensive material was used and the work was not particularly difficult.
• Brazed copper . The more expensive analogue of the previous type of spare part is practically no different in operation, but it is many times better quality and stronger than the prefabricated one. The main advantages of this type of radiator are good heat conductivity and the possibility of its repair: damaged areas can be soldered and used further. The price ranges from 1000 to 3000 rubles .
• Aluminum welded . It has a one-piece body and design where the latest welding methods are used. They are the most reliable and durable compared to other types. The obvious disadvantage of an aluminum radiator lies in its material, because, as you know, aluminum is not the best heat conductor, but has better heat transfer. And they cope with this by increasing the area of ​​the radiator itself. The price is almost no different from the price of an aluminum radiator.

Radiator pipes VAZ 2114

Next comes the upper radiator inlet pipe, connecting the radiator to the engine block head.

This hose goes to injection engines. Its internal diameter is 32mm, see catalog number 21082-1303025.

The next one is the lower radiator outlet pipe, which connects the radiator to the engine cooling system thermostat.

Its catalog number is 21082 – 1303010, internal diameter is 32 mm.

“Angle” pipe for connecting the thermostat to the water pump (pump).

Catalog number – 2109-1303093-01. This pipe fits almost all front-wheel drive VAZ models.

The expansion tank pipe is popularly called the “filler pipe.”

It serves to connect the expansion tank to the thermostat. Through it, antifreeze enters the cooling system when the system is filled or topped up through the expansion barrel. See catalog number 21082-1303080 for its number.

Stove pipes VAZ 2114

The pipe that connects the heater to the block head is often called “big goose” in everyday life because of its resemblance to this bird.

The hose supplies coolant from the block head to the heater radiator. We look at the catalog number 2114 – 8101206.

These considered rubber hoses are reinforced, except for the throttle heating hoses and antifreeze steam exhaust hoses.

The goose curve hose is located under the hood of the car and serves to drain coolant from the heater radiator to the water pump.

Catalog number of the crooked goose 2114- 8101208, factory BRT.

The “short” pipe connects the thermostat to the engine block head.

Shorty catalog number 2108-1303082, BRT plant.

The “small” cabin pipe of the stove supplies coolant to the radiator of the stove, through the tap, from the “crooked goose”.

Its VAZ catalog number is 2114-8101200 from the BRT plant.

The cabin “large” outlet pipe is designed to drain coolant from the heater radiator through the “big goose” hose to the water pump.

Catalog number 2114-8101204 from the BRT plant.

Under the hood, the “big goose” supplies coolant to the heater radiator through a tap. And it takes the liquid to the pump from the radiator of the “goose curve” stove through the “large” cabin hose. For example, thanks to a set of rubber pipes, coolant circulates through the heater radiator.

The rubber pipe, the so-called injection “breather”, serves to connect the valve cover of the block head with the “snail” (2111) for supplying air to the engine.

The upper catalog number of the factory breather is 2111-1014058-10.

All connections presented in the video are located under the hood and in the interior of the VAZ 2114 car, related to the cooling system. In addition to the large breather pipes, small breather pipes and volutes, which serve for the passage of air.

The car also contains well-known gas supply hoses, brake hoses, a vacuum hose, as well as windshield washer fluid supply and others. They will also need to be viewed on video and described in the article.

All rubber hoses in a car need constant replacement, as they are exposed to aggressive liquids and gradually lose their properties. They lose their elasticity, become tanned, crack and sometimes break when used for a long time without replacement.

Therefore, it is recommended to periodically review their condition and replace them if any malfunction is detected.

This video ends the review; I hope that the video will be useful to someone both for information and when servicing their car.

How to remove the stove on a VAZ 2109

Have you ever heard of a stove radiator? Well, if you have a car, you've just heard. Personally, I learned about the stove radiator only after two years of operation of my VAZ 2109 in 2001

Almost all this time I noticed that when the heater in the car was turned on, it smelled of a special smell, but did not pay attention to it

It was summer and when I got my dampness. “After winter the water will dry up.” I thought, but I was wrong. Then I noticed that the antifreeze began to leave the coolant barrel, and that was the last straw of my patience. All this time I was afraid to realize that I had a radiator.

How to choose a truly excellent VAZ 2109 radiator stove

When I walked into an auto parts store, I learned that there are several types: aluminum factory, aluminum not factory, and copper.

After consulting with friends who had not ridden for several years and were faced with the same problem, I learned:

• A copper radiator costs 2 times more than an aluminum radiator, but it does not get very hot.
• The factory radiator costs about 1000 rubles, and is worth getting because it is reliable and stays warm as expected. Its design is stronger than the original VAZ radiator, and has swirlers that slow down the coolant, which contributes to more heating of the radiator. With this radiator, you will begin to feel the warmth in the car as early as 60 engine degrees.
• A non-factory radiator costs 500 rubles, but it’s not worth buying. First of all, it doesn't get hot; secondly, it may leak immediately after replacement. Thirdly, it does not have swirlers, so the antifreeze passes through the radiator.

Radiator replacement steps

To replace the radiator of the VAZ 2109 stove, you do not need to remove the entire panel, since it is written with many instructions, I will tell you how to do this hemorrhoids a lot and with little time. So, let's begin:

If you have a Vaz 2109

, you need:

1. Drain the antifreeze.
2. Remove the panel trim.
3. Remove the panel part from the speedometer.
4. Remove the furnace trim (which is located under the gear handle).
5. Remove the panel mounting screws.
6. Pull the panel with the help of the assistant from the left edge.
7. Unscrew the clamps that secure the nozzles to the faucet (be careful so that any remaining antifreeze can flow)
8. Remove the 3 screws holding the heater cover in place (3 screws will be the problem.) Have a helper pull the panel more firmly
9. That's all. You just need to take out the old radiator, which just goes into the space between the glove box and the store shelf, put the new one in and put everything back together)

And finally, some tips:

1. Don't wait until winter, it's better to do it this summer.
2. Before installing the new stove radiator, glue it to the edge with foam rubber, since the old one was inserted.
3. After replacing the heater core, it is better to go to the overpass and stand up. Thus, there is less chance of a gateway in the radiator.

High Panel Radiator Replacement with Dashboard Removal

Replacing the radiator on a VAZ-2109 with removing the dashboard will take a little longer than without, but the shelf for magazines will remain intact.

Progress

1. Move the front passenger seat as far back as possible.
2. Find the dashboard fasteners on the right and unscrew them.
3. Pull the instrument console towards you and insert a spacer into the resulting gap; you can use a block of wood for these purposes.
4. Close the heater valve and place rubber mats or old rags where coolant may leak.
5. Open the hood and unscrew the expansion tank cap. To reduce pressure, close the lid.
6. The radiator is located between the glove compartment and the lower shelf. To avoid spilling the coolant, perform all actions very quickly. In addition, you will need 2 rubber plugs or champagne corks to plug the holes in the hoses.
7. Place your hands through the gap in the retracted instrument panel towards the part that needs replacing.
8. Remove the lower pipe and immediately plug its hole with the thumb of your left hand, then insert the plug into the hose with your right hand.
9. Drain the coolant from the pipe into a prepared container.
10. Disconnect the heater element and replace it with a new one. Remove the part carefully: first lift it up, then move it a little and pull it down. This will make it easier for you to remove it.

Heating system elements

The stove diagram clearly shows the location of its main functional elements. It should be noted that the design of the stove on the VAZ-2108, 2109 and 21099 models is the same. Many car owners know that the heater in these models is not fully developed. As a result, the interior is not heated properly, so a decision is made to modify the stove with your own hands.

Just in this case, it is important to know the design of the heater so as not to confuse anything

Components:

The design of the stove of the VAZ-2109 car, whether it is a high panel or a low one, is absolutely identical. Therefore, the information presented will be useful to owners of this model with any instrument console.

Knowing the main points and what is located where, you can already try to independently deal with the problems that arise and fix the malfunctions that appear, while saving money and time on trips to the service station.

Disassembling the panel

The simpler the repair, the better. Therefore, it is worth following the path of least resistance. The fact is that the instruction manual requires complete disassembly of the torpedo. But in reality this is extra work, and it is better to avoid it. If you look at the location of the radiator on the right side, you can see that it is enough to raise the panel a few centimeters. This means that you are required to do the following:

1. Empty the glove compartment and unscrew the screws in it.
2. On the right side of the panel, remove the plug that covers the main fastening bolt. It is located at the level of the rear view mirror.
3. Unscrew the two screws that secure the “beard” (the middle part of the torpedo).
4. Carefully inspect the entire surface of the panel; in the lower part along the perimeter there are four self-tapping screws that are used to fasten it to the car body.

Injection system VAZ 21099

The main elements of the injection system are shown in the diagram:

Diagram of the injection system of a VAZ 21099 car

Positions on the diagram:

• 1 – air filter;
• 2 – air flow sensor;
• 3, 4,10, - system hoses;
• 11 – electronic control unit;
• 13 – fuel filter;
• 14 – fuel tank;
• 18 – pressure regulator;
• 20 – injector ramp;
• 21 – nozzle;
• 26 – cylinder head.

How to properly wash the injector on a VAZ 2109 car

To clean the fuel injectors from tarry deposits that appear due to poor quality fuel poured into the gas tank, it is sometimes enough to wash the injector on a VAZ 2109. This can be done in a specialized workshop or with your own hands. The work process is as follows:

Purchased: flushing fluid, syringe, set of new candles.

Advice: It is better to do the work with an assistant who will press the accelerator pedal to maintain the required engine speed.

• Mix 1.5 - 2 liters of gasoline, which is usually poured into the tank, and flushing liquid.
• The hood opens.
• On the hose connecting the intake manifold and the vacuum brake booster, the rubber adapter tube is disconnected.
• Using a syringe, the prepared mixture of washing liquid and gasoline is poured into it.
• About 20 minutes is enough for all the growths inside the device to come off.
• The assistant gets behind the wheel and the engine starts. The accelerator pedal must be held down, otherwise the engine will not maintain speed due to the tube being disconnected.
• The mixture is injected.

Tip: High pressure in the tube can cause the syringe to be pulled inward, so you need to gently press it, and the liquid will flow into the tube itself.

There is no need to pay attention to the black pieces of garbage flying out of it and the emanating puffs of white smoke. All this may be accompanied by various sounds, especially in VAZ 2109 cars, injector cleaning, which have not been carried out for more than three years

Tip: You need to pour in the washing mixture in small portions, this will wash the device better.

• When all the mixture is finished, the engine is turned off and time is given to cool down.
• A new set of spark plugs is installed.
• The engine workplace is wiped with a dry cloth.
• The hood closes.

For VAZ 21099, how to flush the injector is clearly shown in the video. If the injectors are covered with a crust of dark-colored varnish, it is difficult to clean by simple washing. Therefore, for prevention, it is necessary to fill the gas tank with cleaning additives after 5,000 - 6,000 kilometers. The price of the cleaning product is affordable; one bottle is enough for 60 - 89 liters of fuel. This method is more often used to clean injectors on new cars.

Tip: There is no need to clean a contaminated injector with solvent. Dirt deposits can travel through the fuel lines from the gas tank to the rail and injectors, which can completely clog the intake channels and settle on injector filters made of nylon. Solvent is ineffective for removing such deposits, so its use is not only dangerous, but also a wasteful exercise.

It is better to clean the injector using special equipment using adapters to the injector ramp. In this case, the instructions suggest:

• Disconnect: fuel filter, fuel lines, gas tank.
• Turn on the engine and let it run for 40 - 50 minutes with a special flushing mixture supplied under a pressure of approximately 6 atmospheres. This time is enough for the flushing agent to remove dirt from the injectors, ramp, valve and combustion chamber.
• Install new spark plugs.
• To remove any remaining flushing mixture from the engine fuel system, you need to drive the car for several kilometers at high speed.

Using this method, you can wash the injector on a VAZ 2109 car relatively inexpensively. It does not require much effort to dismantle the ramp and injectors, and the effect of the cleaning compounds is good. How to clean the injectors is shown in the photo.

Cleaning VAZ 2109 injector nozzles

Each car owner decides for himself when to flush the VAZ 2109 injector; the only condition is that the work is completed in a timely manner. Then the guarantee of proper operation of not only the engine, but also all components of the VAZ 2109 car increases.

What is a stove fan

A car heater, which is popularly called a stove, is designed to perform a simple and at the same time important function - heating the interior. In addition, the device helps eliminate fogging of windows in cold and damp weather.

During normal operation of the heating system, the temperature in the interior of the “nine” should be maintained at +20 ˚С with the same indicators outside, but only with a minus sign. In the legs, with maximum heating mode, the value should be maintained at +25 ˚С. One of the important components of the stove, in addition to the radiator, is the fan. The purpose of this device, its malfunctions and repairs should be considered in more detail.

Purpose of the device

The purpose of the motor is to increase the efficiency of the heating system and air circulation in the car. Its operation is based on air intake from outside and its subsequent supply into the cabin through the radiator. As a result of the air flow passing through the heat exchanger, the air enters the cabin already warmed up.

Heater operation diagram: a - VAZ 2108; b - VAZ -2108–01: 1- fan impeller; 2 — air duct for heating the windshield; 3 — windshield heating flap; 4 — damper for heating the driver’s feet; 5 — central nozzle flap; 6 - central nozzle; 7- radiator; 8 — heater control damper; 9 — driver’s foot heating window; 10 - internal ventilation duct

Where is the motor located on the VAZ 2108/09

The heater motor on the VAZ 2108/09 is installed in a niche in the engine compartment in front of the windshield, which is radically different from the design of the heater of classic Zhiguli cars, which have a fan installed in the cabin. The unit is an electric motor with an impeller mounted on it, through which air is pumped into the cabin.

Connection diagram

To make it easier to find possible faults with the fan, an installation diagram may sometimes be required, the main components of which are:

• fuse mounting block;
• egnition lock;
• additional resistor;
• fan motor;
• operating mode switch.

The heater motor connection diagram consists of a fuse mounting block, an ignition switch, an additional resistor, a fan motor, and an operating mode switch

Heaters old and new

Finally, we note that the VAZ-21099 of several years of production used heaters with certain design features, which concerned the angle of the radiator and the location of the main shock absorber.

In the so-called old-fashioned stoves (on cars before 1998), the radiator was installed almost vertically, and the main damper was located under the heat exchanger. There was a partition between the rear wall of the case and the radiator, which formed a channel that ensured air flow through the case.

When the damper was open, the air flow moved through the radiator, where it was heated and supplied to the air ducts. In ventilation mode, the main door closed the heat exchanger, forming, together with the front wall of the housing, another channel through which the flow went directly into the air ducts.

Newer model heaters (on 1998 vehicles) had a much smaller radiator angle than older heaters, which are believed to provide a larger area of ​​airflow contact for heat transfer.

The position and shape of the main flap changes (it becomes arched). It began to sit above the radiator. In the closed position (ventilation mode), the damper ensures air movement along the shortest path to the air ducts. In heating mode, it blocked the cold air supply to the air ducts and directed the flow down into the housing, from where it was directed to the heat exchanger.

Expansion tank and its plug

Well, it is impossible to single out the most important element of the system. Here every little thing plays almost a major role. Even the cooling system of the VAZ 2109, the carburetor if installed in the injection system, has one important part - an expansion tank and a plug. At the very beginning it was mentioned that constant pressure is maintained in the system, due to which circulation improves many times. But this is not the last advantage of the sealed type of cooling.

On a VAZ 2109 car, the cooling system works in such a way that the liquid at high pressure boils not at 100 degrees, but at a higher value. This means that it becomes more difficult to destroy the engine. And the expansion tank plug helps maintain pressure. It has two mechanical valves - for inlet and outlet. The first one is triggered when the pressure in the system drops to 0.13 Atm. And the second one opens when the pressure rises above 1.3 Atm. There are, of course, small errors; these are average values.

What does the price depend on?

First of all, you need to know that the cost of a radiator depends on the material from which it is made. But that's not all! Since the price also varies depending on the brand and country of manufacture . You need to know this because the types of car radiators depend on the type of engine and battery power.

Basically, copper radiators for a car are suitable if heating of the interior is also necessary. This will serve you for a comfortable ride. And aluminum ones have less weight and the possibility of its repair, as mentioned above.

Only high quality will allow you to use your iron horse comfortably and without problems without the risk of harming other parts, because their breakdown is a great inconvenience not only for your car, but also for you. Therefore, you need to buy a quality product with a guarantee.

How to make a car heater burn fiery in winter

Useful lifehacks

And, finally, a few useful life hacks to improve the operation of the stove in the Russian winter.

Closing the radiator

On some car models sold on the Russian market, electric cooling radiator shutters are installed as standard or plastic screens are applied, by installing which you can partially block the flow of incoming air to the cooling radiator. This is a simple and effective way to speed up the heating of the interior and improve the operation of the stove in extreme cold. If such devices are not available, you can make them yourself

However, it is important to take all precautions to prevent self-ignition of the screens - they should not come into contact with hot elements of the engine compartment

Reducing the air flow through the stove

In extreme cold, some car enthusiasts increase the air flow through the heater radiator to the maximum, and are surprised that the heater still does not warm up the interior well. The secret is simple: passing through the stove at high speed, impressive volumes of cold air simply do not have time to warm up. By reducing the speed of the motor, you will increase the heating of the interior.

Open the window slightly

In some cases, good heating of the interior is hindered by the design of the car itself, or more precisely, by an ill-conceived ventilation system. If the body ventilation valves are not working and the doors are well sealed, increased pressure is created in the cabin, and almost no air escapes outside. Every minute it becomes more and more difficult for the heater motor to pump oxygen into the car. By lowering one of the windows slightly, you will increase the flow of air through the heater and, possibly, improve the climate in your car.

Experiment and you will undoubtedly find the best way to improve the efficiency of the heater specifically for your car!

How to choose a really excellent radiator for the VAZ 2109 stove.

When I went to an auto parts store, I learned that there are several types. Aluminum factory. non-factory aluminum and copper.

After consulting with friends who have been driving for several years and have encountered such a problem. I found out :

• A copper radiator costs 2 times more. than aluminum. but it's not very hot.
• A factory radiator costs around 1000 rubles and is worth taking. because It is reliable and heats as expected. Its design is stronger than the original VAZ radiator and has swirlers that slow down the coolant, which contributes to more heating of the radiator. With such a radiator, you will begin to feel warmth in the car already at 60 degrees of the engine.
• A non-factory radiator costs 500 rubles, but it’s not worth buying. First of all, it doesn't heat up. secondly, it may leak immediately after replacement. Thirdly, it does not have swirlers, so the antifreeze flies through the radiator without having time to heat it up.

Having learned all this, I went to the store and bought an original DAAZ radiator, price 750 rubles. It looks like this:

Heater radiator: how to replace and choose a new one

The heater radiator in the VAZ 2109, no matter how long and how well it works, always starts leaking suddenly. Usually you notice either drops of antifreeze on the passenger mat, if it begins to flow along the seams at the edges of the radiator, or you find antifreeze under the mats, if it flows deeper - in the area of ​​​​the stove pipes or the faucet of the VAZ 2109 stove. If this happens, it’s time to think about replacing the radiator stoves, and also about which new stove radiator to choose. This is what we will talk about today. I’ll tell you based on my practical experience, since recently a similar fate befell my car - it started dripping onto the front passenger’s rug from somewhere on the left from under the panel. Looking there, we found leaks along the edges of the radiator. It should be noted that antifreeze flows from the edges of the radiator into the area of ​​the pipe clamps, so at first you might think that the connection between the lower pipe of the heater and the rubber hose is leaking. However, by tightening the appropriate clamp, we make sure that the leak does not decrease - which means it’s time to change the radiator.

Choosing a stove radiator

There are several types of heater radiators for the VAZ 2109 - original aluminum, non-original aluminum and copper. A copper radiator is much more expensive than an aluminum one, but it can be soldered in case of a leak, and it is more reliable than aluminum. Also, according to reviews, it is colder, and it is not available everywhere. Now let's see how the original radiator differs from the non-original one. Firstly - the price. The original costs at least 750 rubles, while the non-original may well cost 450 rubles. Now let’s pay attention to the radiator plates: in the original they are located much closer to each other - there is a larger heat transfer area. Also, the edges of such a radiator do not bend so easily, and the design of the original VAZ radiator itself is stronger.

Above is the original DAAZ, below is Fenox for 450 rubles. The difference is obvious. The edges were wrinkled when removed from the stove body

Therefore, with an original radiator, the air from the heater nozzles begins to warm up already at a coolant temperature of 60 degrees, while with a non-original radiator the heat will only reach closer to 90 degrees - you will freeze during short trips. Also inside the original radiator there are coolant swirlers in the form of spiral ribbons in the radiator tubes. They increase its operating efficiency due to the fact that the coolant does not fly through the radiator under the pressure of the pump, but is slowed down by them and rotates, transferring heat to the radiator more efficiently.

I can’t say how to determine their presence in non-original ones, no one will let you disassemble the radiator when buying, but I think that they should rattle a little inside if you shake the radiator. Therefore, I recommend only the original. Its packaging looks like this:

Replacing the stove radiator

To replace the heater radiator on a VAZ 2109 according to the instructions, you need to remove the entire front panel. However, if you have a tall panel, many people do the following. You need to unscrew all the screws securing the panel to the car body, remove the steering casing and simply move the right edge of the panel into the cabin with the help of an assistant.

In this position, the heater radiator should pass just between the glove compartment and the glove compartment.

When using this method, I recommend moving the panel away carefully so as not to tear anything off; under the steering wheel there are bundles of wires from the ignition switch and alarm elements that can be attached to the panel; all this needs to be detached from it.

There is also this method, although you will have to cut up the instrument panel. You can make the bottom shelf removable, which prevents you from removing the radiator from the stove body. To do this, you can saw it off, and then attach it to self-tapping screws, and remove it later when replacing the heater radiator.

True, on injection machines, an additional block with a relay hangs under the bottom shelf, so the bottom shelf must be securely fastened. But changing the radiator is a pleasure!

What to do if the VAZ 2109 stove blows cold air. Modernization of a standard stove

Cooling system pipes VAZ 2114, 2115

Greetings, Lada VAZ car enthusiast on the RtiIVAZ website!

A YouTube channel subscriber came up with the idea to make a video about the rubber radiator pipes of the VAZ 2114 and the heater pipes of the VAZ 2114, just like his car. This video was filmed at the request of Boris Zverev, and the article was edited on the initiative of Albert Aukhadullin.

Let's start with the steam exhaust hose of the cooling system. This hose serves to remove steam from the radiator to the expansion tank. The length of this product is slightly more than one meter, the diameter of the internal hole is 8 mm.

This hose is installed on VAZ 2108, 2109, 21083, 2113, 2114 and VAZ 2115 models with injection and carburetor engines.

On models of the “ten” family, the same hose is installed as in the photo above, catalog number 2110-1303095.

Next we will consider the hoses installed to heat the throttle assembly.

These are inlet and outlet hoses for coolant. The diameter of the hose when measured with a school ruler is about 10 mm, and the length is 48 cm.

Stages of replacing a VAZ stove radiator

To replace the radiator of the VAZ 2109 stove, you do not need to remove the entire panel, as is written on many instructions; I will tell you how to do this without unnecessary hemorrhoids and with little time. So let's get started:

If you have a VAZ 2109, then you need:

1. Drain the antifreeze.
2. Remove the panel trim.
3. Remove part of the speedometer panel.
4. Remove the heater trim (which is located below near the gearshift lever).
5. Unscrew the panel mounting screws.
6. Pull the panel with the help of an assistant from the left edge.
7. Unscrew the clamps that secure the pipes to the faucet (be careful, the remaining antifreeze may leak)
8. Unscrew the 3 screws securing the heater radiator cover. (There will be problems with the 3rd screw. Ask an assistant to pull the panel harder)
9. OK it's all over Now. All you have to do is take out the old radiator, which just fits into the space between the glove compartment and the magazine shelf, install a new one and assemble everything in reverse order (Be careful not to tear off the wires from the ignition and alarm switch)

And finally, a couple of tips:

1. Don't wait until winter, it's better to do it this summer.
2. Before installing a new stove radiator, peel it off along the edge with foam rubber, just as the old one was covered.
3. After replacing the heater radiator, it is better to go to an overpass and stand so that the front is much higher than the rear of the car and rev it up. This will reduce the likelihood of an air lock in the radiator.

Video “Step-by-step replacement of the radiator on a VAZ 21099”

Learn more about how this process is carried out in the video below (the author of the video is the Engine Repair channel! And interesting!).

Heating of the interior of any car is provided by air, which is heated in the heater radiator. The VAZ 2109 heater radiator is connected in parallel to the main radiator, which is part of the cooling system of a car engine.

The heater itself is secured with four nuts in the passenger compartment under the instrument panel to bolts that are welded to the air supply box. The air heated in the heater is directed through an air duct system into the passenger compartment. The air ducts are attached to the instrument panel from below and sealed with gaskets.

Typical faults

As with any mechanism, problems can occur in the heating system (video author - Andrey Kuzemsky).

If the VAZ 2108 heater motor is broken, you can understand this by comparing some symptoms:

1. If the motor does not work when switching operating modes, the cause of the breakdown may be hidden in the resistor. When repairing, you need to replace the resistor with a new one, because it cannot be repaired.
2. If the fuse is blown, you need to check the insulation of the armature located on ground. There may be a short circuit.
3. If, when switching modes, the VAZ 2108 heater fan rotates at the same speed, this may be a consequence of contamination or oxidation of the collector. In case of repair, it is worth cleaning the collector and, if nothing has changed and the fan continues to act up, you can replace the bearings.

If the VAZ 2108 stove motor does not even show signs of life, then the reason is not in its design, but in a broken circuit. To find out if this is true, you can use a voltmeter.

Features of the fan and thermostat VAZ 21093, 2109, 21099

The electric fan includes an electric motor and a four-blade impeller, the blades of which have a variable angle of inclination and pitch to reduce noise levels. To increase efficiency, the VAZ fan system is equipped with a casing attached to brackets.

The electric fan is mounted on rubber bushings. The fan is triggered by a signal from a sensor installed in the radiator tank. In this case, the contact closure temperature is approximately 99'C, and the fan shutdown temperature is 94'C.

The system thermostat provides priority warming up of the engine and regulates the thermal regime. The optimal coolant temperature is within 90-98'C. The thermostat includes a body and a cover, rolled together with the valve.

Features of the VAZ injector cooling system

Cooling in cars 21093,2109,21099 is liquid, but you need to understand that the radiator is cooled by the flow of incoming air and a fan, which increases the cooling intensity. Also, part of the heat is removed by the car's interior heater radiator at low temperatures.

The expansion tank is designed to compensate for the volume of liquid when heating, to top up and control the level of antifreeze.

The temperature sensor provides control of the cooling system, allows you to monitor the engine temperature and regulate the operation of the fan.

The entire operating cycle of the cooling system is controlled using a power unit control system that takes into account all temperature parameters. It determines the optimal switching conditions and operating time of the structural elements of the system.

Some useful tips

Finally, here are some tips to ensure that your car heater serves you for as long as possible.

1. When deciding to replace the heater core, do not skimp. It is better to buy a high-quality original part once than to bother with its repair or replacement every year.
2. Never use products of dubious origin and composition as coolants.
3. Do not allow the radiator to remain idle for long periods of time without fluid. Even in summer, open the heater tap at least once a month to circulate coolant through it.
