Many owners of Daewoo cars often encounter the fact that the Lanos stove does not heat well. Here it must be said that on new machines it works quite effectively, but over time the quality of operation of this unit decreases significantly. The owners share their experience on how to solve this problem. Among the reasons, some highlight the fact that the Korean car was initially designed for milder climatic conditions, and certainly not for the Russian winter. Even the dimensions of the radiator on all modifications of Lanos are significantly smaller than on models from VAZ. And if those who are faced with this problem replace the part with a more efficient one, then nothing will come of it. There is simply no room to install a thicker heater radiator in the Lanos. Naturally, you can try and install it, but you will have to remove the dashboard and the ventilation system. Also, all this will not work without depressurizing the air conditioning system. In addition to dismantling all these components, the internal structure of the stove box will have to be reworked. The entire system needs to be completely redesigned.
Radiator clogged from outside
This problem can be diagnosed by the same temperature of the stove pipes and a lower air flow coming out of the diffusers. In this case, the blockage does not occur instantly, but over a long period of time - a decrease in the flow force cannot be noticed immediately. It is best to check the flow strength in comparison with a working model. On a Lanos of any production, be it a Daewoo, Chevrolet or ZAZ, there is no cabin filter. The heater radiator, and with it the evaporator for the air conditioner, are easily clogged with various debris - it can be fluff, leaves, anything. Naturally, such a blockage does not allow air to pass through the radiator freely. And as a result, the Lanos stove does not heat well, and it becomes very uncomfortable in the car.
Air in the radiator
This is another reason why the stove does not heat well on the Chevrolet Lanos and other modifications of this model. With this malfunction, the temperature of the stove pipes will vary significantly, the fan will turn on more often, and the thermostat will open. In this case, removing excess air from the radiator is not an easy task. It is located in the ventilation system box at a certain angle. If you do not intentionally remove air, then at first the Lanos stove does not heat well, and then it may stop working altogether. You can try to remove the airiness entirely. To do this, you need a slide where the car can be placed at an angle of 30 degrees or more. It should be remembered that after some time the air pockets will return again, so the procedure should be repeated over time. This case is due to a jet falling into the expansion tank from the throttle heating system. When this same jet falls, air bubbles dissolve in the antifreeze and eventually spread throughout the system. Many whose Daewoo Lanos car's heater doesn't heat well have noticed that the problems started after the first year of owning the car. This malfunction can have two main causes - coolant, which was kindly added during assembly of the car, or bubbles.
What to do if the Chevrolet Lanos stove does not heat?
Unlike other brands in the budget segment, the Chevrolet Lanos is equipped with an autonomous heating system. Heating of the windshield and interior with a flow of warm air together with the air conditioning system. This design has advantages and disadvantages. Let's take a step-by-step look at why the stove on a Chevrolet Lanos does not heat well.
Principle of operation
The standard Lanos heater is located in the central part of the front console of the car. During the circulation process, heated air is supplied from the heating radiator. For maximum efficiency, the Chevrolet Lanos interior heating system must be sealed and without damage. Heating begins when the car engine is started. The heat exchanger and evaporator are installed in one block.
The driver activates the control lever, adjusts the speed and temperature indicators. An air flow of a given degree is supplied for heating through channels and deflectors.
Heating system elements
- Radiator: warms up the air flow by circulating cooling system fluid inside the heat exchanger.
- Electric drive – supercharger: takes air flow into the car interior. Sometimes it is called an impeller or a motor. The preset regulator allows you to mechanically select the optimal position and number of revolutions.
- Heater damper: air flow regulator, with its help we increase or decrease the air temperature inside the cabin.
- Distribution regulators: adjust the airflow to a specific area or the interior as a whole.

Causes of poor heating
Chevrolet Lanos car owners sometimes encounter the fact that the heater blows cold air. The reasons for this “behavior” are different. To correctly identify, you will need experience in servicing the equipment. Otherwise, you risk causing harm with unprofessional intervention. Visit a service station for preventative measures.
Common reasons:
- the critical fuse has blown: the electric motor does not start, no current flows;
- air lock in the system: an obstacle is created to the natural circulation of antifreeze through the channels. The heat exchanger does not receive the required temperature, the air flow does not warm up, so the Lanos stove heats poorly;
- breakage of the standard radiator fasteners: the cause is either mechanical damage, an accident, a collision, or a natural factor. Lanos models produced after 2000 are “endowed” with a similar defect. The radiator moves to the side, the main flow passes by the honeycomb, so the stove does not heat well. Prompt repair of the Lanos stove and cooling system radiator is required;
- clogged antifreeze supply channels: the word “garbage” should not be taken naturally. In relation to cars, we are talking about sediment, the presence of third-party impurities in the composition of the liquid. Poor manufacturing or natural aging leads to the formation of subsidence and cloudiness. A large amount of “garbage” contributes to the formation of clots that block the antifreeze supply and circulation channels;
- mechanical cable break: the last, but most common malfunction due to which the stove does not work. The disadvantage of the design of the Chevrolet Lanos heating system is the absence of an autonomous tap that would shut off the centralized supply of coolant to the heater. Systematic contact with hot antifreeze leaves a negative imprint on the service life. Due to the formation of fossils, the cable's travel is limited and it breaks under force.

How to solve the problem of poor heating
If the Chevrolet Lanos stove does not heat up, then you can eliminate the defect in two ways: by contacting a workshop or by yourself modifying the Lanos stove yourself. Each owner chooses stove repair methods based on financial capabilities and availability of free time.
Troubleshooting algorithm
- The car is in transport position, open the hood and check the level of antifreeze in the cooling system. If necessary, add to the o.
- We start the engine, activate the heater lever, check the uniformity of heat flow through the channels (hoses).
- We start from the upper radiator supply circuit and gradually move into the interior. If the hoses are uniformly warm and there are no cold sections, then the heater radiator is clogged and needs to be cleaned. You can dismantle the radiator without disassembling the torpedo. We remove the gearbox rocker and the central tunnel. We wash the product and install it in the reverse order.
- If the motor does not start: check the integrity of the fuse in the block. Replacing it with a new one will not be a problem. Exceeding the permissible current contributed to burnout.
- The worst option is a break in the heater damper cable: there is nothing to recommend other than complete dismantling and disassembly.
Cable replacement process
- remove the plastic trim on the central part of the dashboard, in the area of the radio;
- carefully remove the insert made of polymer material on which the mechanical levers of the stove regulator are installed;
- From the inside, remove the cable end from the attachment point. We carry out a similar procedure in the lower part of the stove heater, near the damper. It's inconvenient, but it can be removed;
- pull out the damaged cable, insert a new one, and assemble in the reverse order.
We visually diagnose adjacent parts and mechanisms for damage. If necessary, we replace with new spare parts. With this simple preventative measure we restore the functionality of the stove heater. Do not forget to carry out technical inspection of the car in a timely manner, this will extend its service life.
Fighting air pollution: insertion into the system
This situation can be dealt with - to do this, move the return hose of the throttle heating system under the expansion tank. Then a tee is cut in there and the coolant is replaced. To avoid problems with the stove, this is done as soon as possible after purchasing the car. If the stove on a Chevrolet Lanos does not heat well, it is better to eliminate the reasons for this immediately. The outer diameter of the large pipe should be approximately 20 mm. The size of the small fitting should be about 10 mm. As for the length, these are 6 and 3 cm, respectively.
Tire size on Kalina (factory)
According to the manufacturer's data, three tire sizes can be installed on the Lada Kalina. It depends on the year of manufacture of the car. So, let's look at what options exist for installing tires on the Lada Kalina:
- The most common size option is 175/70R13 . This is the standard size of “Zhiguli” tires, which takes its history back to the “Classics”.
- The second most popular size on a VAZ, but the most common on Lada Kalina is 175/65R14 .
Standard version of wheels for Lada Kalina in LUX configuration: 6.0×15 4*98 ET 35 dia58.6
All other tire size options are non-standard and are not recommended for installation on the Lada Kalina.

. Considering that winter is just around the corner. This is enough.
Weak tightness
This is one of the common phenomena that the stove does not heat well (Chevrolet Lanos is no exception). The reason lies in the lack of tightness of the seams in the ventilation duct, and this is most evident in the winter.
It is very easy to check - if it is frosty outside, the heater fan control is moved to the fourth position, and the air flow is directed to the windshield. Then the hand is carried out in the places where the parts of the ventilation duct are connected. If some areas feel cold, then the interior is cooled with air from outside. This problem can be solved by simply coating the cracks with sealant. To obtain the maximum effect, a corrugation is attached to the damper lever - a part from the mirror adjustment knob is perfect.
Search for repairs
Having considered all possible ways to improve heating, we can conclude that all of them will be ineffective without a remote thermostat and an organized coolant intake from it. Possible reasons for poor operation of the heating system For a good understanding of this issue, we will highlight the main reasons for the unsatisfactory operation of the heater: The solution may be to simply add coolant slightly above the average limit of the expansion tank.
Before embarking on more serious activities, you should start with this method. This is the most common breakdown, why the Chevrolet Lanos stove does not heat well.
To determine the damage, it is enough to strongly move the heater hoses in different directions in the engine compartment. If instability is felt, then it can be assumed that the radiator mount is damaged.
Summary
If the stove on a Chevrolet Lanos does not heat well, what should you do in this case? Check the heating system thoroughly. Problems can hide in the most unexpected places. Well, you should definitely use the experience of experienced lanosovodov.
With the onset of cold weather, mechanics at service stations very often hear the same problem: the stove on a Chevrolet Lanos heats poorly or does not heat at all. Let us note right away that this is one of the “diseases” of this car. The heater on the car is not designed in the best way. Even a working stove does not heat quite as well as we would like. And all because the car was not designed for the harsh Russian winter.
So, in your Chevrolet Lanos the heater is blowing cold air, and you are freezing and constantly scrubbing the windows, you are nervous. Of course, the situation is disgusting, even dangerous, and requires immediate correction.
There are quite a few reasons why the stove does not heat up on a Chevrolet Lanos. Let's look at the most common of them.
The Chevrolet Lanos heater does not heat up: what to do?
The Chevrolet Lanos heater does not heat up - the problem is quite common, and almost every motorist who has owned one car for many years has inevitably encountered the fact that the heater began to heat poorly.
Chevrolet Lanos heater does not heat: reasons
The simplest reason why the Chevrolet Lanos heater does not heat well is the failure of the fan due to a blown fuse. In the same way, the electric motor switch can fail. All that needs to be done in this case is to change the fuse responsible for the electric motor or fan. They cost pennies, but they change on their own within three minutes.
The thermostat has failed
The second reason why the stove does not heat well on a Chevrolet Lanos is a broken thermostat. This device is quite fragile and easily breaks down. How to recognize that the thermostat is broken? When the engine is warm, the antifreeze temperature needle will rise very slowly and not reach the desired value. Also touch the pipes connecting the radiator and thermostat. They will either heat up very quickly (although the stove, according to the sensors, has not yet warmed up), or will remain cold. There is only one solution - replacing the thermostat.
Airiness of the system
The third possible failure is air in the system. Diagnosing this is also easy. In this case, in the engine compartment, the temperature of the inlet and outlet pipes of the heater radiator varies greatly. The fan turns on frequently. Removing air is not difficult. Go up the hill (by car, of course, at about an angle of 30 degrees), remove the expansion tank cap and press the gas pedal all the way down several times. Experts warn that after about a year, air may accumulate again, so carry out this procedure every autumn to avoid freezing in winter.
Maybe the radiator is failing?
The fourth reason is a clogged radiator. You can try flushing the channels. Most often this is done using a pump and a container with a washing solution. At home, this is warm citric acid.
How to rinse: remove the heater radiator pipes, connect the pump and run the solution in a circle several times. It helps, but not always. The problem may be in the radiator itself. Then it needs to either be repaired or, in general, replaced.
Failure of fastening
The fifth reason is the most interesting. The design of the heater radiator mounting itself fails. High temperatures, poor quality plastic and heavy loads lead to the fact that the fixing bracket wears out and the radiator gradually breaks off from the air duct. It is not difficult to imagine that cold air then enters the cabin through the cracks. Here, no matter how hard your stove tries, there will be a glacier in the cabin.
At service stations, the reason why the stove on Lanos does not heat well is encountered quite often. Therefore, experts advise not to let things get into trouble and to additionally secure the fastening with self-tapping screws or hooks in advance. Please note that everything must be done carefully so as not to break the honeycomb. Then, if the stove on Lanos starts to heat up weakly, you won’t have to worry about the fastening breaking off.
Now you know almost all the probable reasons why the stove on a Chevrolet Lanos does not heat well, and you understand the intricacies of the heating system of this car no less than an expert. Having checked all the points indicated in the article before the onset of cold weather, you can with almost 100% probability not be afraid that your “swallow” will let you down in winter.
Why does the Chevrolet Lanos stove heat poorly? We eliminate the reasons ourselves
Putting up with them is dangerous not only from the point of view of getting colds (which, by the way, is also unpleasant and always at the wrong time), but also from the point of view of traffic safety: the windows freeze, there is no visibility, and constantly wiping them off distracts you from the road, which is fraught with in an accident. The heater needs to be dealt with urgently, and I would like it to be done without extra costs. First of all, you need to find out what caused his abnormal behavior.
Why does the Chevrolet Lanos stove heat poorly?
and how to eliminate sabotage on her part, we will tell below.
There may be 2 options: the coolant does not reach the required temperature
. The most common culprit for this is the thermostat: it breaks quite easily. It is not difficult to recognize it in this capacity: firstly, when the engine is warm, the coolant temperature gauge crawls extremely lazily to the desired place, and then stops before reaching the desired mark. Secondly, you can touch the pipes connecting the radiator and thermostat. If the latter malfunctions, they either heat up almost instantly (the stove has not yet reached 70°C, according to the instruments), or they will remain cold. There can be only one repair here: replacing the thermostat.

It could be the radiator itself. Then it needs to either be repaired or, in general, replaced. Failure of fastening The fifth reason is the most interesting. This whole thing is located under the hood, in the engine compartment.
If both tubes are cold, you need to fix the problem.
Does the stove heat poorly on Lanos? Stove repair in Chevrolet Lanos - construction
This is done extremely. The main thing is that the stove does not warm the Chevrolet Lanos very well; do this carefully so as not to damage the honeycombs. In any case, in order for the stove to work more or less normally on a given car, it is advisable to check it at least from time to time for any of the malfunctions. Let's try to figure out what the causes of this problem are and how to deal with them. Poor sealing One of the most common reasons for low temperatures inside a car in winter is insufficient sealing of the ventilation duct seams.
It’s quite simple to check: If we feel cold in certain places, then you can be sure that the stove is not warming the Chevrolet Lanos well, that the interior is being strongly cooled by cold air from outside.
The problem is solved without much difficulty: During cold periods of the year, its walls are cooled to such an extent that they reduce the temperature directly in the cabin no worse than an air conditioner.
Ideally, this work should be carried out after the tightness problems have been eliminated. The process itself is simple, but requires preparation in the form of removing the panel. You can, of course, try to avoid these difficulties, but the result may be disappointing and you will have to do everything all over again.
Lack of tightness in the radiator itself. The reason that the heater in the Chevrolet Lanos heats up poorly may also be a defect in the radiator itself, namely insufficient tightness.
This is especially true for models where the stove does not warm the Chevrolet Lanos well; the inlet and outlet openings are located on one side. Normally, they should be separated by a solid partition, otherwise the air will simply move from the incoming fitting to the outgoing one, without increasing the temperature of the radiator itself.
It is easy to test for such a breakdown, but to do this you need to remove the radiator. Next, turning the radiator upside down with the fittings, fill it with water.
How to fix poor heating of the stove on a Chevrolet Lanos
After this, close the fittings, return the radiator to its original position and open one of the pipes. When all the water has flowed out, open the second pipe.
If the partition is without defects, a sufficient amount of water will still flow out of the second fitting. If the heater does not heat the Chevrolet Lanos properly, there is practically no more water. Improving the cooling system If you have eliminated all the points described above, but the stove in Lanos still does not heat well, then you need to move on to improving the cooling system.
