Many owners of Daewoo cars are often faced with the fact that the Lanos stove does not heat well. Here it must be said that on new machines it works quite efficiently, however, over time, the quality of this unit is significantly reduced. Owners share experiences on how to solve this problem. Among the reasons, some highlight the fact that the Korean car was originally designed for milder climatic conditions, and certainly not for the Russian winter. Even the size of the radiator on all modifications of the Lanos is much smaller than on models from the VAZ. And if those who are faced with this disaster replace the part with a more effective one, then nothing will come of it. There is simply no place to install a thicker radiator stove in the "Lanos". Naturally, you can try and install it, but you have to remove the torpedo and ventilation system. Also, all this will not work without depressurization of the air conditioning system. In addition to dismantling all of these nodes, you will have to rework the internal structure of the stove box. It is necessary to redo the entire system.
On the Lanos car, the stove is not warming well: reasons
So, there are several typical malfunctions, which, according to the owners, can be the reasons for the inefficient operation of a standard heating system. Perhaps not all are described here, but the list is based on the personal experience of lanosovodov.
The radiator of the stove is clogged inside
If the “Daewoo Lanos” car does not heat the stove well, then you should check this unit directly. Hoses in the heating system give off a completely different temperature. The thermostat opens more often than necessary. The radiator fan also often turns on.
Why is the radiator clogged? The reason for this may be the antifreeze that drivers pour into the system. If the fluid is of poor quality, deposits begin to form inside the lines. Most owners try to flush the radiators and the main with
phosphoric acid solutions
, descalers, even Coca-Cola. And sometimes these methods help, but more often flushing does not give a result. As a result, the stove still heats badly ("Lanos 1.5" is no exception). In garage or home conditions, the
washing process of the
radiator of the stove is carried out using three pieces of hose and a warm solution of citric acid. In addition, under such conditions, an antifreeze test can be performed. Liquid is poured into two containers. Then a little soda is poured into one of the vessels. A little of any acid is added to another container. If no chemical reaction has started in either the first or the second tank, then the Lanos stove does not heat well due to the radiator - the antifreeze is quite high-quality.
Radiator clogged outside
This problem can be diagnosed by the same temperature of the nozzles of the stove and a smaller air flow leaving the diffusers. In this case, the blockage does not occur instantly, but over a long time - a decrease in the flow strength cannot be noticed immediately. It is best to check the strength of the flow compared to a working model. There is no cabin filter on the Lanos of any production, be it a Daewoo, Chevrolet or ZAZ . 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 freely pass through the radiator. And as a result, the Lanos stove heats badly, and it becomes very uncomfortable in the car.
Also, after a while, the air conditioner may start to “smell” in the absence of a cabin filter. This happens due to dust that accumulates during operation of the machine. It settles on the evaporator, thereby creating favorable conditions for the development of various microorganisms and harmful bacteria. The garbage can be easily removed using an ordinary vacuum cleaner - for this, the fan is dismantled, a hose is introduced into the box without any nozzles. At the same time, it is recommended to purge the system through diffusers.
Air in the radiator
This is another reason why the stove heats up poorly on the Chevrolet Lanos and other modifications of this model. With this malfunction, the temperature of the stove nozzles will vary significantly, more often the fan will turn on, and the thermostat will open. In this case, removing excess air from the radiator is not an easy task. It is located in the duct of the ventilation system at a certain angle. If you intentionally do not deal with the removal of air, then at first the Lanos stove heats poorly, and then it may completely stop working. You can try to remove the whole airiness. To do this, you need a slide where the car can be put at an angle of 30 degrees or more. It should be remembered that after some time the air jams 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 antifreeze and eventually spread throughout the system. Many people who have a bad heat in a Daewoo Lanos car have noticed that the problems started after the first year of owning the machine. This malfunction can have two main reasons - this is the coolant, which was kindly poured during the assembly of the car, or bubbles.
Airborne Control: Tie-In
You can deal with this situation - for this, the return hose of the throttle heating system is transferred under the expansion tank . Then a tee cuts in and the coolant is replaced. In order not to have problems with the stove, this is done in the very near future after purchasing a car. If the Chevrolet Lanos does not heat the stove well, the reasons for this are best eliminated immediately. The outer diameter of the large pipe should be approximately 20 mm. The size of the small nozzle should be about 10 mm. As for the length, it is 6 and 3 cm, respectively.
Practice shows that it is possible to struggle with airing even without installing the machine on the hills - a flat platform is also suitable. The same applies to airing itself - plugs are not formed from the jet from the collector heating system. Therefore, you do not need to cut the nozzles. This is not an option. To be afraid of air congestion is also not necessary.
Early opening thermostat
Experienced owners, if the stove does not heat well (Chevrolet Lanos and Zaz Sens, among others), recommend checking the standard thermostat. On what is installed in the car, its operating temperature is indicated (it is 86 degrees).
However, most often it opens and passes antifreeze much earlier. Why does the stove on Lanos not heat well? Yes, because the temperature of the coolant is not yet sufficient, but it went through the engine through a small gap in the half-open thermostat. Antifreeze gets on the radiator of the stove unheated. This is clearly visible when the machine is just warming up and the thermostat opens for the first time - the supplied air becomes even colder. It is much better that the stove heats the interior when the thermostat opens for several times.
How to fix the thermostat problem?
The owners of these cars recommend purchasing another thermostat - for example, designed for a temperature of 92 degrees. With this unit, the motor will not overheat in winter, and the element itself will open on time.
In general, over time, any products get sick with an early opening - therefore, after a while the stove at Deu Lanos does not heat well, and the owner is nervous.
Winter problems
In winter, the owners of these cars turn to service stations with problems in heating almost every day. Let's try to understand the problem, especially since in this case the reasons are slightly different.
Poor tightness
This is one of the frequent phenomena that the stove heats poorly (Chevrolet Lanos is no exception). The reason lies in the lack of tightness of the joints in the ventilation duct and this is manifested as much as possible precisely in the winter.
It is checked very easily - if there is frost outside, the heater fan regulator is moved to the fourth position, and the air flow is directed to the windshield. Then a hand is carried out in places where the parts of the ventilation duct are connected . If in some areas it feels cold, then the interior is cooled by air from the street. 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 - the part from the mirror adjustment knob is perfect.
Cold ducts
Before getting into the radiator of the heater, the air goes a fairly long way in the duct system. In winter, the walls of the duct are cooled significantly and reduce the temperature in the cabin. It gets very cold inside.
To solve this problem, air ducts are insulated with any heat-insulating material (for example, splen). These works are recommended to be carried out after the problem with tightness is solved. The process is not difficult, however, it may be necessary to dismantle the panel.
Summary
If the Chevrolet Lanos car does not heat the stove well, what should I do? Check the heating system thoroughly. Problems can be hidden in the most unexpected places. Well, you should definitely use the experience of experienced lanosovodov.
