The stove on the VAZ 2114 does not heat well: we find out the reasons and fix the problem

In winter, driving without interior heating is a dubious pleasure. But VAZ 2114 owners often encounter this situation, because their stove stops working.

Today we will understand the structure of the stove, consider the main causes of malfunctions and ways to eliminate them. Alas, the stove may not heat for a whole list of different reasons. Your task as a car owner is to find these causes and eliminate them. Do it yourself or with the help of car services, decide for yourself.

car heater

What is a stove and its functions

In the engine cooling system, the heater takes part of the heat, directing it into the car interior and maintaining the desired temperature there.

It is a whole chain of interconnected parts:

1. Pipes.
2. Stove radiator.
3. Tap for adjusting the antifreeze level.
4. Dampers with air ducts that control and direct air flow.
5. Electric fan.

The combination of these elements ensures an uninterrupted supply of air to the car interior and maintains the desired temperature in it. What to do if the VAZ 2114 stove does not heat well, the stove has completely stopped working? We will indicate the main causes of the malfunction.

What does the VAZ 2114 car heating system consist of?

Its details:

1. Radiator.
2. Special pipes with circulating liquid.
3. A valve responsible for adjusting the optimal level of circulating fluid.
4. Special dampers that control the air.
5. Air duct.
6. Electric fan.

When working properly, the air flow should move freely through all nodes of the above-described system.

Why the stove does not heat well on a VAZ 2114, or the stove either heats or does not heat, you will find out further.

Cylinder head gasket

Sometimes the cause of the malfunction is hidden in a burnt-out cylinder block gasket.

You can determine whether the gasket is intact by these signs:

1. Antifreeze smells like gasoline and contains exhaust gases.
2. When the engine is running, white smoke comes out of the exhaust pipe.
3. There is a light mixture on the dipstick and oil filler cap.

If at least one of these signs is detected, you need to urgently check the condition of the gasket and replace it if necessary, otherwise the problems will be much more serious.

Thermostat

When the stove on a VAZ 2114 does not heat well, the thermostat may be the cause. The valve does not open, which causes a disruption in the circulation of the coolant. The engine boils quickly, and the heater doesn't work well or doesn't work at all in winter. You need to check if the valve is working. With the engine warm, touch the upper and lower hoses of the main radiator; they should be hot.

If one of them is cold, the valve is faulty. Or remove the thermostat and heat it in a container of water. Before the water boils, the valve must open. Does not open, needs to be replaced with a new one. The thermostat is inexpensive. Experienced car enthusiasts advise changing them according to the time of year, guided by the fact that the colder it is outside, the lower the valve opening temperature.

The first thing I would do is check the heater valve and the cable that opens it. Maybe it's not fully open. You can simply use a warm engine and with the tap open, feel the pipes that go to the heater radiator in the cabin (under the panel on the passenger side). They must be hot! Well, check the coolant level. And then put the cardboard behind the bars) roll up the branch

That's why our mechanic kept talking about his Mazda. Allegedly, he removed the cabin filter from it and put it in the trunk. But since he has a Mazda, this does not mean that tag has a similar device. I, too, on our Surgut forum, heard about opening the faucet. Supposedly you pull the valve. and the faucet does not open until the gallery. Autonasheprom headache. Okay, I'll take a look.

Thanks to everybody, you're free.

aaaaaaaaaaaaa. here's another thing. I heard that instead of cardboard, a tourist rug can be thicker if you roll up a branch

I had a 99, the stove didn’t work well on it, so I accidentally came across a half-closed faucet, and then everything worked well, although not for long)))) a month or two and I crashed the car

Any additional device that is installed in a car is designed to enhance the power of a stationary unit, which alone is unable to function as the motorist desires. The same rule applies to the second heater, which is often installed in the interior of domestic vehicles. The second stove, which will be located inside the VAZ-2114 interior, will be able to optimize the process of warming up the car, especially in cases where it is incredibly cold outside. In the material below we will consider the types of various additional heaters that can be installed in the VAZ-2114. We will learn about the advantages and disadvantages of this type of insulation, which is quite possible to do with your own hands.

Radiator

The reason could be the radiator. Over time, its honeycombs become clogged with debris and dirt, causing the supply of warm air to become weak. In this case, the radiator is washed with appropriate solutions. It happens that honeycombs are damaged mechanically, which impairs the circulation of coolant.

Radiator for VAZ 2114

This radiator cannot be repaired. And you only need to buy new, not used. To replace, you must disassemble the front panel and console. Drain the antifreeze from the radiator through the tap into a container. Then remove the pipes from it and unscrew the fastening bolts. After installing a new one, fill in antifreeze. It is recommended to pour into the expansion tank in small portions to avoid the formation of air pockets. Fill 200-300 ml. You need to wait a few seconds and add more until the system is full.

Repair work

Knowing the structure of the stove, it is easy to repair. Before starting repairs, it is necessary to remove the wire from ground and drain the coolant.

Repair consists of the following steps:

1. First you need to remove the instrument panel and carefully disconnect the air pipe through which air enters the cabin.
2. Next, you should check the electrical system: resistor wires, electric motor, fan. In addition, you need to check the outlet and inlet hoses of the faucet.
3. Next, you should unscrew the two nuts from the shield that secure the faucet.
4. Then you need to remove the seal from the tap pipes.
5. Next, the nuts are unscrewed, with which the stove is attached to the body.
6. Now you can remove the stove.
7. Having completed the necessary repairs and adjustments, the heater is reinstalled in the reverse order.

After repairs, you should check the operation of the heating system. It should turn on as soon as the engine starts.

Airlock

Another reason why the 2114 heater does not heat well at idle may be airing in the system. After turning off the engine, air sometimes enters the radiator from the expansion tank and remains in the area of ​​the thermostat. And the next time you start the engine, air will circulate instead of liquid. As a result, the engine heats up quickly and the heater does not work.

Air lock on VAZ 2114

To get rid of this trouble, loosen the coolant pipe clamp and slowly fill in antifreeze to the desired condition. It should be remembered that the liquid must be used of the same brand; mixing is strictly prohibited. You can try driving up a steep slope in front, remove the cap from the expansion tank and wait about 5 minutes. Usually the system itself pushes unnecessary air out.

Unable to adjust temperature

Often, owners of domestic cars (including VAZ-2114) are faced with the impossibility of setting the air temperature on the control unit. The stove blows equally hot or cold, regardless of the position of the main lever of the automatic control system (in the photo below - located in the center).

In this case, experts note a malfunction of the dampers or malfunctions in the operation of the control unit itself. The temperature sensor is also diagnosed. It is located next to the light control lamp on the ceiling. Rotate the position of the lever several times. The heating of the air should change tactilely. If the temperature changes only when the sensor is in the extreme position, the element must be replaced.

Prevention

And in order not to wonder, sitting in a cold car, why the stove stopped working, you need to regularly inspect all the heating elements of the car. Clean periodically. Change antifreeze more often. From time to time, check the condition of the pipes and tap leading to the radiator for leaks. If you notice cracks on a part, it is better to immediately replace it with a new one. It is recommended to completely flush the system at least once every 2 years.

Why does the stove heat poorly or not heat?

Below are the main reasons for a poorly functioning or non-functional stove, as well as ways to solve the problem.

1. The stove fan does not turn on. The heater fan (interior heater) does not work.
2. Thermostat not working. If the thermostat is not working, then it constantly circulates coolant in a large circle, which does not have time to heat up, and as a result, the stove does not heat. You need to check the thermostat and replace it: How to check the thermostat? How to replace the thermostat?
3. Airlock. An air lock is formed as follows: after the engine is running, when the coolant cools, air penetrates into the upper part of the radiator, from where it moves to the thermostat. In the morning we start the engine, and the pump circulates air into the interior heater radiator. To remove an air lock, use the corresponding article: How to remove an air lock?. There is also another way: we drop the pipe onto the stove, and slowly add antifreeze there until it is full.
4. The stove faucet does not open completely. In 90% of problems with a poorly heating stove, the problem lies precisely in this. In this case, you do not need to tighten the cable of the stove faucet. You need to bend the cable from the gas pedal; when you bend over, you will see it. You just need to use pliers to pull the cable to increase its tension. If the stove faucet does not open, then most likely it has soured and needs to be replaced: How to replace the stove (heater) faucet? If you still try to open it, there is a chance that you will rip it off and flood everything with coolant.
5. The heater radiator is clogged. In this case, you need to remove the heater radiator and thoroughly blow it out or install a new one: How to replace the heater radiator?
6. Fan impeller. If the heater radiator is hot, then the problem is most likely in the fan impeller. There is a multidirectional impeller.
7. Poor quality heater radiator. The fact is that there is a Ukrainian-made heater radiator. This radiator simply does not provide for high heat transfer to the interior by design. Therefore, it is better to use a DAAZ radiator.
8. The pump does not create the required pressure. If, for example, the stove does not heat up at idle, and the stove only heats up at speed, then the problem is with the pump. The bottom line is that the pump does not ensure normal circulation of coolant and then the fluid is weak. Similar symptoms are also accompanied by low coolant levels. Instead they put in a duralumin pump, Belmag. There have been a lot of fakes of HEPU lately, so I don’t advise you to use this manufacturer.
9. Low coolant level. The coolant level should be at the max mark or a finger higher (in winter).
10. There is an option to add an electric pump from Gazelle.
11. The cylinder head gasket has burned out. If oh. the liquid smells like gasoline or exhaust; The engine oil smells wow. Liquid; Thick white smoke is coming from the muffler, then the cylinder head gasket has most likely broken.
12. The cabin heater filter is clogged. Replace the filter by following the link: How to replace the stove cabin filter?

One of the weak points of domestic cars is the stove, which constantly breaks down. Thus, this article covers the topic - the VAZ 2114 stove does not heat well. As a rule, there are dozens of reasons that lead to this malfunction, however, some of the factors are the most common. This article will look at just such reasons.

The most common reasons:

1. Air lock. 2. Problems with the stove faucet (leaking, incomplete opening). 3. The fan (impeller) does not work. 4. Radiator clogged (poor quality radiator). 5. The pump does not create the required pressure.

Air lock - solution:

As a rule, air pockets form after the engine is running, at the moment when the antifreeze cools down. Air enters the radiator and enters the thermostat. If you then start the engine, the pump expels air into the heater radiator. In order to get rid of an air lock, you must perform the following steps:

• Disconnect the hose from the carburetor fitting. • Open the cap of the expansion tank and blow forcefully until antifreeze flows out of the fitting. • Reconnect the hose to the fitting.

Problem with the stove tap - solution:

Quite often the problem lies in the stove faucet, which either leaks or does not open completely. In this case, the range of solutions is quite wide, including replacing it with a water ball valve. Thus, it is recommended to act according to the situation, if possible try to preserve the original part:

• If the faucet does not open completely, then the part may be soured. You can try to tighten the cable, bending it from the gas pedal side, using pliers. You must act carefully so as not to rip off the tap. • If the faucet is completely out of order, it is recommended to contact a service station or try to replace the part yourself.

The fan does not work - solution:

Often the problem is hidden in the fan. Sometimes there is a situation when the radiator is hot, then, most likely, the fault is hidden in the impeller (sometimes there is a multidirectional option). In cases where the fan does not work, you can think about replacing it or looking more carefully for the cause of the malfunction.

Radiator clogged - solution:

The vast majority of VAZ car owners are well aware that the radiator must be periodically cleaned of lime, dirt, etc. Some motorists even have their own recipes for cleaning the radiator. However, inexperienced beginners are recommended to solve the problem at a service station.

The radiator is clogged - what to do:

• It is necessary to stock up on cleaning liquid and appropriate tools (screwdrivers, keys, basins, etc.). • Carefully push the fluid through the radiator. • It is advisable to use good quality cleaning products.

The pump does not create the required pressure - solution:

In such situations, when the stove does not want to heat up at idle, but works normally during stable operation, the reason most likely lies in the pump. In this case, the pump does not provide the necessary circulation of coolant, resulting in a weak flow. Similar symptoms are observed with low levels of antifreeze. The solution to the problem may be to replace the old part with an aluminum pump. It is advisable to use a high-quality option.

Among other things, the stove may not work well for reasons such as low antifreeze levels, a burned-out cylinder head gasket, a poor-quality radiator, or a malfunctioning thermostat. Having found out the cause, it will not be difficult to fix the malfunction yourself or at a service station.

If the stove on a VAZ 2114 does not heat, then this is a big problem in the winter season. Let's consider the main causes of device failure and ways to eliminate them.

Stove valve malfunction

All cars use a valve that shuts off the flow of coolant through the heater radiator. It is he who is controlled by the “heat - cold” switch on the center console in the cabin. For various reasons, the faucet may not open all the way. In this case, the stove does not heat up at idle speed, since not enough hot antifreeze enters the radiator.

The solution is simple - the faucet must be replaced. We advise you to choose high-quality spare parts, since cheap taps quickly fail and jam in the closed or open position.

The main reasons for the ineffective operation of the heating device

1. The device fan does not turn on. To understand that the fan is not working, you need to turn on the heater at 1-3 intensity with the car running. If no extraneous noise occurs, then the element does not work. It could fail due to a blown fuse, loose contacts in the mounting block, stuck ignition relay, etc. 2. Faulty thermostat. The stove on a VAZ 2114 also does not heat well if the thermostat does not work. The liquid that it circulates does not have time to heat up - hence the problems. 3. Air lock. The reason why the stove on a VAZ 2114 does not heat up may be a traffic jam. It occurs when air enters the radiator and then into the thermostat after the engine has stopped running. When the ignition is turned on, air enters the heater core. The device is not operating at full efficiency. To eliminate the air lock, just add antifreeze. 4. Problems with the faucet. In most cases, the problem of why the stove on a VAZ 2115 does not heat well is hidden in a malfunction of the faucet. If it does not open, then it is necessary to replace it, as it has soured. Attempts to open it may result in coolant flooding the interior. 5. The radiator of the device is clogged. You need to remove it to clean it or replace it with a new one. If the device is clogged, it is enough to blow it out under pressure. 6. Fan impeller problems. A multi-directional impeller reduces the efficiency of the heating device. 7. Low quality heating radiator. It is not recommended to purchase Ukrainian radiators, since the distribution of heat into the interior from them is not provided for by the design. It is better to choose the DAAZ model. 8. Lack of required pressure. If the stove heats only at high speed, then the problem is in the pump. This element does not organize the normal circulation of the liquid, which affects the flow of the liquid. It is enough to change the pump to normalize the flow of coolant. 9. Cooling fluid level is low. If the stove on a VAZ 2114 does not heat well, then you need to check the level of cooling fluid. It should be set at maximum or higher. 10. The cylinder head gasket has burned out. The reason why the stove on a VAZ 2114 does not heat well may be a violation of the integrity of the cylinder head gasket. This is easy to recognize: the coolant begins to smell like gasoline, and white smoke comes out of the muffler. 11. Cabin filter clogged. The filter is used to purify air coming from the street. It is located in the engine compartment. Not all cars come with a filter. To check whether it is there or not, you need to press on the stove casing. It is recommended to change the filter only when the air flow into the vehicle interior is very low.

In a number of domestically produced cars, one of the main, frequently encountered problems during the cold season is the poor functioning of the heating system. Experience shows that there are more than a dozen reasons that lead to such a problem. In our article we will look at the main points and factors leading to poor performance of the heating system. The reasons for poor performance of the VAZ-2114 heater are similar to the reasons for the VAZ-2109. You can read more in the article: The VAZ 2109 stove does not heat well. And now more details about the fourteenth.

WE FIX THE PROBLEM OURSELVES

This also happens - at high speeds the stove “breaks through” and it starts to heat up, but at idle speed the fan blows cold air. Why doesn't the VAZ 2114 heater heat up at idle? We immediately note that if you are the owner of a VAZ 2113 or VAZ 2115, then all solutions to problems with the lack of heating of the interior will be similar to the solutions with the 2114 model. So, we are trying to find simple solutions to the problem ourselves:

1. Insufficient coolant level. Add antifreeze; if the stove breaks, the problem is solved.
2. Airlock. How to check? In the area of ​​the heater radiator, the characteristic murmur of antifreeze is heard, the temperature sensor on the instrument panel shows almost maximum (almost boiling), one of the main radiator pipes is cold. You need to remove the expansion tank cap, press on the pipes and “gas” the engine. Perhaps the plug will break. It happens that the valve itself in the tank plug is to blame; you can try replacing it. It is also often advised to park the car on a hill, with the plug removed, “gas” the engine, and then add antifreeze when the plug “breaks”.
3. Also, if one of the pipes is cold and the temperature on the sensor goes off scale, a faulty thermostat is to blame. It's easy to check. We remove and place the thermostat in a container of water, heat the water and see at what temperature the thermostat valve begins to close. It should open at engine operating temperature (90-95ºC). The faulty part needs to be replaced.
4. The head gasket begins to burn out. With such a malfunction, an air lock is created in the cooling system, but it will not be possible to expel it using all known methods. The gasket will have to be changed. True, not every car enthusiast can do such work with his own hands.

Removing the thermostat

Causes

The main reasons why the stove does not heat well:

• Airiness of the system.
• The stove faucet has failed. Leakage or incomplete opening.
• Fan failure. There is no warm air supply.
• Defective radiator unit or clogged.
• There is no necessary pressure created by the pump.

Airiness of the system

As the antifreeze cools after the engine is running, air pockets may form. The next time you start the engine, the pump expels air into the radiator unit of the heating system.

To resolve this issue, you must do the following:

• Disconnect the hose from the carburetor fitting.
• Remove the cap of the expansion barrel and thoroughly blow it out so that antifreeze flows out of the fitting.
• Connect the hose to the carburetor fitting.

Work to eliminate air pollution has been carried out.

Broken faucet

The presence of a faucet leaking or its incomplete opening often creates a malfunction of the vehicle’s stove heating system. In such cases, the variety of solutions is very wide. To solve this problem, in some cases, even replacing the ball valve is required.

We recommend that you take steps to fix this problem without replacing the original faucet:

• The reason for poor opening of the faucet may be the formation of a build-up on it, which led to oxide on the part. Try tightening the cable by bending it with pliers from the side of the driver's door. Act very carefully so that the tension does not lead to the faucet breaking.
• If the faucet completely fails, we recommend contacting an auto repair shop or replacing it yourself.

Heater fan failure

A fairly common reason for the lack of normal heating of the car interior is poor operation of the fan or its failure. If you observe strong heating of the radiator, we advise you to first pay attention to the impeller, or rather to the presence of multidirectionality in it. If the fan completely fails, try to determine the reason that caused its inoperability, or replace it

Radiator block clogged

Any radiator cylinder needs periodic cleaning to remove lime and dirt deposits. Many car enthusiasts even have a personal recipe for cleaning the radiator block. For all beginners, if such a problem occurs, we recommend contacting a car service center.

If you want to clean the radiator block yourself, you need:

• Have a container, a set of wrenches, cleaning fluid and screwdrivers available.
• It is necessary to carefully pass the liquid through the radiator block.
• Use a cleaning fluid that is reputable and of high quality.

Poor pressure in the engine cooling system

If the stove does not heat well at idle, and if there is normal functionality while moving, pay attention to the performance of the pump. In these cases, the pump does not ensure normal circulation of antifreeze. There may also be a lack of antifreeze in the system. To solve this problem, it is necessary to either add antifreeze to the appropriate level, or replace the outdated pump with a duralumin pump

Deterioration in the performance of stove heating can also be observed due to: burnout of the cylinder head gasket, failure of the thermostat, insufficient amount of antifreeze and defective radiator unit. After determining the cause, it will not be difficult for you to eliminate it yourself or by contacting a service station.

Let's consider one of the most common problems in VAZ 2114 2113 2115 cars - the stove does not heat or does not heat well.

The stove works, but cold air blows on the glass.

In rainy weather, the windows constantly sweat. The problem is that on the air temperature regulator (cold-hot), the damper that cuts off the cold air flow does not close completely, as a result, cold air enters the glass and sometimes into the side air ducts. At the same time, warm/hot air is blown into the legs and into the central air duct. It's all about the cable that is attached to the damper, this is what it looks like:

It is located under the plastic trim to the right of the driver. The problem with it can be solved very simply with the help of ordinary round nose pliers. Here is a real example of such a problem in the video:

The stove doesn't work, the air doesn't blow.

If the heater motor is working properly, but warm or cold air does not flow through the air ducts, then most likely the “heater relay” is faulty; it is located under the steering wheel on the left and can be easily changed. It looks like this:

What you should pay attention to if the stove in a VAZ 2114 2115 2113 does not heat well

:

1. First of all, look at the coolant level; if it is minimal, the stove will begin to heat up the interior poorly. This malfunction is quite easy to fix; just add coolant to the required value. Just wait until the engine has cooled down before opening the expansion tank cap.

2. Check that the thermostat is working properly. When it doesn't work properly, the heated antifreeze doesn't reach the heater, resulting in a cold car.

3. A clogged cabin filter can affect the flow of warm air into the cabin, resulting in poor heating of the windows.

4. In severe frosts, place cardboard on the radiator; this is a simple but very effective remedy in severe frosts.

Installation of additional components

Owners of the domestic VAZ-2114 most often decide to install a second heating device because the standard device is not of very high quality. The VAZ-2114 stove is small and, importantly, not airtight. The valves do not function entirely correctly; the faucet is not able to open to full power. If a car owner wants an exceptionally comfortable temperature in the cabin during the cold season, he will have to constantly open and close the tap, and most likely the pump will soon fail. The optimal additional pump for the VAZ-2114 stove is a turbo version with greater performance. You can install a Bosch pump (it must be installed at the outlet of the stove).

If the heater radiator on a VAZ-2114 car fails, a copper unit can be installed in its place. In foreign-made cars, an electric hair dryer is installed that preheats the air, due to which the antifreeze quickly heats up and streams of warm air begin to flow into the cabin almost instantly. As for the VAZ-2114, its small-volume heater “forces” cold air flows to pass through the radiator, which is why the antifreeze itself cools down greatly.

Instead of thinking about replacing the cabin filter, it is more prudent to install an additional radiator in the car that can warm up the air coming from the street in advance. You can purchase a radiator that comes with an air conditioner. It is best to buy a unit that is ideally sized. After installing the new device, everything should be laid with isolon, which will guarantee complete tightness.

As practice shows, an additional pump is needed solely to warm up the car when the power unit is activated. After some time has passed, it must be turned off, because pressure will be present in the system, and the antifreeze will warm up at that time. After installing the second heater in the VAZ-2114, it can be quite hot in the cabin; good ventilation of the cabin will not hurt. It would be prudent to install a faucet at the inlet of the second radiator.

CAUSES OF FAILURES IN VIOLATED

OPERATION STARTING OPERATION OF FAN IN HEATING ROOM When

SYSTEM of such a malfunction, the stove will have to be disassembled to find the breakdown. But before that, you need to start the car and turn on all three fan power levels one by one. If there is no additional noise, then it’s time to start disassembling.

VAZ in Also 2114 the stove does not heat if the thermostat is faulty. With such a breakdown, the cooling liquid circulates in a circle without having time to cool.

ACCUMULATED AIR CLOGGAGE

An air lock in the cooling system can form if the engine has already stopped running. At this moment, the temperature of the coolant begins to decrease. It is then that air can leak into the upper part of the radiator, and then the thermostat moves. Later, when starting again, the engine pump will drive the accumulated air from the radiator to the heating system thermostat.

Helpful advice: to easily get rid of the air lock, you need to remove the pipe and slowly fill in antifreeze to the maximum.

TAP marks

Attention, the most common nine. In ten cases, the reason is that the faucet does not open completely. There may be two reasons for this problem: it is completely out of order and must either be replaced; it is poorly secured and, due to the heater cable, it is located near the pedal assembly. The cable needs to be tightened a little by grabbing it with pliers.

If the stove does not supply hot air to the cabin at the same time, and the faucet is leaking, then the latter must be urgently replaced. At this point, a greasy coating forms on the glass, and the same stains may appear on the floor, and a pronounced smell of antifreeze and faucet hovers in the atmosphere of the cabin.

THE RADIATOR IS CLOGGED IN THE HEATING SYSTEM

If the heater radiator is clogged with dirt and debris, then the heater does not blow well and the warm air flow barely enters the cabin. unnoticeably especially unpleasant if there is decent frost behind the glass.

THE QUALITY OF THE RADIATOR IN THE HEATING SYSTEM LEAVES THE BEST

This kind of news about the performance properties of the radiator is most often received by car owners who have purchased a used VAZ 2114 before the onset. And until the cold weather in the summer, they don’t even suspect the problems ahead. Also, a bad radiator can be installed at a car service center. A gullible customer who did not control the results of the work of the master can become a victim of deception and negligence. In any case, the bad radiator will have to be replaced with a high-quality one. There is no radiator here.

heater options for VAZ 2114

Radiator replacement procedure:

• Disassemble the front panel and remove Drain.
• Console antifreeze into a special clean container (radiator) through either the drain hole.
• Remove the center panel, glove compartment, side panels.
• Unscrew the screws and bolts that secure the panel to the body and to the body.
• metal to remember the cables.
• Push the freed side into the dashboard.
• Remove the pipes.
• Take out the old one and replace it with a new radiator.
• Screw all other serviceable parts into their original places.

LOW If

PRESSURE There is not enough pressure in the heating system on the 2114 VAZ, the stove does not heat up at idle. This pressure is provided by the pump. It is easy to track and recognize this cause of a malfunction: while driving, heat enters the cabin. The way out of the situation is to replace, preferably, the pump with an aluminum one produced by Belmag.

Duralumin BELMAG pump for VAZ 2114

LOW ANTIFREEZE

On the 2114 VAZ, the stove does not heat well if there is a shortage of coolant in the heating system. It is necessary to check the antifreeze level here. Depending on the temperature and season outside, it can be different: in summer the coolant should be at least below the “max” mark, in winter – two fingers above the maximum scale. In any case, you just need to add antifreeze.

Topping up antifreeze on a VAZ 2114

BURNT CYLINDER HEAD GASKET

Signs of a burnt cylinder head:

• The coolant has a new unpleasant smell of gasoline and car exhaust.
• The engine oil began to smell like coolant.
• A thick white burnt sound suddenly poured out of the car muffler.

smoke, the cylinder head gasket needs to be replaced.

BROKEN MOTOR

The motor of the stove itself may also fail, or simply before. But before you start the procedure, it’s worth replacing it to make sure that the temperature switch is in working order and the operating mode of the ignition relay is in good condition. To do this you need to free yourself from the pipes. Pull out the old faulty stove and put a new one in its place. Make sure it works again and fill it with coolant.

The answer to a popular question from car owners about how to improve a VAZ with a 2114 stove is the prevention of breakdowns.

Major heating problems

Every car enthusiast runs the risk of encountering a situation where the heater controls are turned on full, but there is simply no thermal effect in the cabin. In this case, it is most likely impossible to do without disassembling the heating element. But before you start dismantling, you need to be fully aware of why you are doing it. Let's look at the main malfunctions of the stove.

1. Problems with the thermostat. They can be easily diagnosed by a side effect - the speed of warming up or overheating of the engine. If the thermostat is stuck in the open position, then the coolant will flow out in a large circle, causing the engine to warm up longer. And we get a situation in which the engine runs normally, seems to be fully supplied with fuel from the injector, but takes an awfully long time to heat up. If the thermostat gets stuck in the closed position, the opposite effect will occur (the stove will also not work).
2. Airing. Have you filled in new antifreeze and noticed that there is no heating in the car? There may be a traffic jam. Diagnosing a malfunction is not difficult: you just need to start the engine, let the car warm up, wait for the fan to turn on and touch the pipes connected to the tap fittings. If the temperature on one of them is different to the touch, the problem can be considered detected.
3. Radiator clogged. This problem occurs especially often after untimely replacement of antifreeze. The longer the old fluid is in the system, the more it will be deposited on the walls.

These are not all possible breakdowns. But no matter what happens to your stove, it needs to be removed and repaired.

We will talk further about how to do this, and also talk about the main nuances that need to be taken into account when removing the device.

PREVENTION METHODS

To avoid a repeat incident First:

• A preventive measure will be required - this is advance disassembly of the system and cleaning of each part.
• The presence of a clean cabin filter under the hood. As you are dirty, you understand that a clogged filter prevents the flow of hot air, and for the same reason the radiator becomes covered with a large layer of dirt.
• Fresh antifreeze. It needs to be changed regularly and maintained properly. Then. level, the air supply to the radiator through the thermostat will be uninterrupted.
• Hermetically fixed tap and this. You can check the radiator when the engine is well warmed up.

A functioning heating system will be confirmed by well-functioning, silent operation of the fan and a continuous flow of warm air even in a static position. Good luck.

Am I freezing in my Samara or why doesn’t the stove on the VAZ 2114 work and warm up? The relevance of this topic is more relevant than ever at a time when it’s the height of winter and cold weather outside, and not everyone’s car is warm. This problem is typical not only for used cars, but also for new cars. What plays a role here is the factor of poor quality assembly, and not the manufacturing defect of the part.

If such a breakdown occurs, you can fix it on your own, but not everyone knows about it, and sometimes there is no money or time to send it to a service center. To help many car owners quickly eliminate the cause of the breakdown, consider the article below with recommendations about the heating system.

Preventing the operation of the stove in the car

In order for the stove in your car to heat well and not let you down at the most inopportune moment, you need to follow a few simple tips.

1. Keep the radiator clean. Light contamination from the outside of the radiator can be removed with a vacuum cleaner. Flushing the engine cooling system, with which the heater radiator is inextricably linked, will help get rid of internal deposits and blockages in the channels.
2. Use good antifreeze . High-quality antifreeze is the key to long-term operation of not only the stove in the car, but also the engine. Remember this and do not forget to replace it in a timely manner.
3. Change the cabin filter more often . A clogged cabin filter will certainly create problems not only for the operation of the stove, but also for the air conditioning and cabin ventilation system as a whole. In addition, dust and pollen deposited in the filter can pose a serious health hazard (especially for allergy sufferers).

If, at an outside temperature of minus 25 °C, your car’s heater heats the interior to +16 °C from below and up to +10 °C from above, then it can be considered quite serviceable. To avoid problems, it is recommended to carry out preventive measures in a timely and responsible manner that will allow you to enjoy a comfortable ride in a well-warmed-up car.

And remember, the longer the service life of the machine, the more attention its heating system requires. This applies to all cars, regardless of country and manufacturer.

Common Causes

The stove on the VAZ 2114 does not work and does not heat, then find out the reason from the list below and fix the problem

:

• The heater cooler does not work. It may be broken or no electric current is supplied to it. It is necessary to ring the circuit with a tester and the source of the breakdown will become known;
• The thermostat is stuck. When not working, it will circulate only cold liquid in a circle, as a result of which the stove heater will not be able to heat up. In this condition, the thermostat cannot be repaired; most likely, prepare for a complete replacement;
• An air lock that forms after we turn off the engine. An air space is formed in the upper part, which at the next start is drawn in by liquid and moves into the heater radiator. This can be eliminated in the following way: loosen the clamp and remove the heater radiator pipe, add as much antifreeze as possible into the radiator through a watering can and put the structure back together. Antifreeze under pressure will squeeze out the air, and this way the circuit will be heated. The root cause was a low level of coolant in the radiator;

The list is certainly not exhaustive, but it lists the most basic ones so that the driver can immediately get his bearings and start searching. There may be situations where none of the above points apply, although this is unlikely.

This problem is most typical for VAZ cars, unlike foreign cars. But nevertheless, you can calmly deal with it and prevent it from reoccurring in the future.

Let's hope that our recommendation article on the topic of the stove on a VAZ 2114 not working and not heating will help you eliminate the cause, especially in 20 degree frost and on the road, so that you can continue your journey in warmth and comfort.

Probably one of the most unpleasant breakdowns that can happen to a car in winter is heater failure. The heating system takes on special importance in cold weather - no one dares to argue with this statement.

For what reason the stove in a VAZ-2115 car does not heat, and how exactly to eliminate such a problem, we will tell you in the article below.

Heater device

The stove installed on the VAZ-2115 injector is exactly the same as on the earlier “nine”. The main elements of the heating system are as follows:

• fan;
• radiator;
• air ducts;
• damper rods;
• heater valve;
• resistor;
• motor;
• thermostat.

Coolant, heated from a running 8-valve engine, enters directly into the radiator. The fan blows on the metal plates of the heat exchanger and the air heated in this way enters directly into the interior of the car.

Immediately after the heating circuit is turned on, the heating valve opens and supplies antifreeze to the radiator.

The rods regulate the air supply and the direction of its jets. With their help, you can provide heating to the windshield or direct hot air to frozen feet. By including a resistor in the circuit, it is possible to create a certain resistance, which allows you to regulate the operation of the heater. The thermostat ensures the movement of coolant through two circuits (small and large).

If the last device jams, then the movement of antifreeze occurs only through one of them, which increases the risk of overheating of the power plant. The heating of the car interior is organized through a large cooling circuit. That is, if the thermostat gets stuck on low, heating will not occur.

Often there are also problems with the fan motor. In this case, warm air will not be able to pass through the air ducts and deflectors in the cabin.

As you might guess, in general, the heating system is quite simple, and has previously been used in many other cars. New cars usually do not have any problems of this kind, but over time, as they are used, the chances of a breakdown increase significantly.

Lower nozzles

Next we will upgrade the leg ducts. When disassembling the panel, you will see that there is a large gap between the nozzles. We seal it with a corrugated tube. We take the standard air distributor out, and in its place we also install a corrugation.

The diameter should be 4 centimeters. This way, the air will be clearly directed to the feet, without leaks. As for the windshield blower, it is being modified in a similar way. Additionally, the owners fill the extra cavities with polyurethane foam in order to eliminate the creaking of the panel when moving (this problem has plagued the Samara since the first generation). Judging by the reviews, this method works.

Why did the stove start to blow poorly?

In reality, there can be many reasons why the heating system in the VAZ-2115 does not work. These include, in particular:

• burnout of the cylinder head gasket;
• thermostat jamming;
• fan motor failure;
• airlock;
• the pump located in the radiator for some reason does not create the necessary pressure;
• The heating tap did not open completely.

In the first case, there is usually a significant decrease in the coolant level. Repairs should not be delayed, as this will lead to overheating of the vehicle unit.

If the thermostat is jammed, the antifreeze begins to circulate only in a small circuit and does not have time to cool properly.

If the radiator is clogged, the air blows weakly from the deflectors. You will have to clean it or replace it with a new one.

The plug usually appears after the car engine is turned off - air accumulates in the cooling system. When the engine is started again, it is pumped into the radiator and makes normal coolant circulation impossible.

Incomplete opening of the heating tap, in turn, can occur due to the fact that it is clogged or as a result of weakening of the cables that drive it.

A breakdown of the pump leads to a loss of pressure, and, therefore, the stove does not blow at all, or very poorly.

The rods that open the dampers of the air ducts directed at the windshield or at the feet often become unusable. In this case, it happens that the system that does not allow cold air to enter the cabin has broken down. Here you will have to start regulating its drafts.

Video “Reconstruction of the VAZ heating system”

This video explains how to make the cabin warmer and therefore more comfortable (the author of the video is Alex ZW).

Owners of domestic vehicles, for example, such as the VAZ 2114, periodically encounter a problem that appears in winter - the heater stops functioning properly. Problems may result in the fact that warm air stops coming from the stove or the motorist will not be able to turn on the heating unit at all. Therefore, in such a situation, when the windshield of a vehicle is covered with a layer of dense ice “blanket”, which obstructs normal visibility, the motorist must know how to act correctly at such a moment. In view of this, if problems arise with the heater, you must first understand the structure of the system and know the circuit diagram of the unit, which will help find the cause of the malfunction.
