Why does the Lanos stove badly heat?

Many owners of Daewoo cars often face the fact that the Lanos stove does not heat well. Here it is necessary to say that it works quite efficiently on new machines, but over time the quality of this node's operation is significantly reduced. Owners share experiences on how to solve this problem. Among the reasons, some people emphasize that the Korean car was originally calculated for milder climatic conditions, and certainly not for the Russian winter. Even the dimensions of the radiator on all modifications of Lanos are much less than on the models from the VAZ. And if those who are faced with this disaster, replace the detail with more effective, then nothing will come of it. Places for installing a thicker radiator stove in the "Lanos" is simply not there. Naturally, you can try and install it, but you will have to shoot the torpedo and the ventilation system. Also, all this will not work without the depressurization of the air conditioning system. In addition to dismantling all these units, it is necessary to rework the internal structure of the furnace box. It is necessary to completely redo the entire system.

On the car "Lanos" bad heats the stove: the reasons

So, there are some typical malfunctions, which, in the opinion of the owners, can be the reasons for the inefficient operation of the regular heating system. Perhaps, not all are described here, but the list is made on the basis of the personal experience of the Lanosovods.

The heater radiator is clogged from the inside

If the car "Daewoo Lanos" bad heater heats, then it is worth checking this site directly. Hoses in the heating system give a completely different temperature. The thermostat opens more often than necessary. Also often turns on the radiator fan. Why is the radiator clogged? The reason for this may be in the antifreeze, which the drivers are pouring into the system. If the liquid is of poor quality, sediments begin to form inside the lines. Most owners are trying to wash the radiators and the main with solutions of orthophosphoric acid, scale agents, even Coca-Cola. And sometimes these methods help, but more often the washing does not give a result. In the end, it's still bad heating the stove ("Lanos 1.5" is not an exception). In garage or home conditions, the process of washing the radiator of the stove is carried out with the help of three pieces of a hose and a warm solution of citric acid. In addition, under such conditions, it is possible to test the antifreeze. Liquid is poured into two tanks. Then a little soda is poured into one of the vessels. A little bit of any acid is added to another container. If neither the first nor the second tank started any chemical reaction, then the Lanos stove does not warm badly because of the radiator - the antifreeze is of good quality.

Radiator clogged from the outside

Diagnose this problem at the same temperature of the stove nipples and a smaller flow of air coming from the diffusers. At the same time, the blockage does not occur instantaneously, but for a long time - the decrease in the flow strength can not be noticed immediately. It is best to check the strength of the flow in comparison with a working model. On the "Lanos" of any production, be it "Deu", "Chevrolet" or ZAZ, there is no salon filter. The radiator of the heater, and with it the evaporator for the air conditioner, is easily littered with various garbage - it can be fluff, leaves, anything. Naturally, such a blockage does not allow air to pass through the radiator without hindrance. And as a result - the stove "Lanos" badly warms, and the car becomes very uncomfortable. Also after a while, the air conditioner can start to "smell" in the absence of a salon filter. This happens because of the dust that accumulates during the operation of the machine. It settles on the evaporator, thereby creating favorable conditions for the development of various microorganisms and harmful bacteria. Garbage can easily be removed with an ordinary vacuum cleaner - to do this, remove the fan, insert the hose into the box without any attachments. It is recommended to blow the system through the diffusers together with this.

Disturbance in the radiator

This is another reason why the heater does not heat the Chevrolet Lanos well and other modifications of this model. With this malfunction, the temperature of the stove nipples will vary significantly, the fan will often turn on and the thermostat will open. To remove excess air from the radiator in this case is not an easy task. It is located in the box of the ventilation system at a certain angle. If intentionally not to deal with the removal of air, then first the Lanos stove does not heat well, and then at all it can stop working. You can try to remove the whole air. This requires a slide, where the car can be put at an angle of 30 degrees or more. It should be remembered that after a while 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 very stream falls, the air bubbles dissolve in the antifreeze and eventually spread throughout the system. Many who have a bad heater on the Daewoo Lanos car have noticed that the problems started after the first year of ownership of the car. This malfunction can have two main causes - a coolant that has been graciously filled in when assembling a car, or bubbles.

Combating air-blasting: inserting into the system

With this situation you can fight - for this under the expansion tank carry the return hose of the throttle heating system. Then the tee cuts into it and the coolant is replaced. In order not to have problems with the stove, it is done in the very near future after the purchase of the car. If the stove does not heat the Chevrolet Lanos, the reasons for this are better to be eliminated immediately. The outer diameter of the large pipe should be approximately 20 mm. The size of the small choke must be about 10 mm. As for the length, it is 6 and 3 cm respectively. Practice shows that it is possible to fight with airing without mounting the machine on the hills - even a level platform will do. The same is true of the airflow itself - the plugs are not formed from the jet from the collector heating system. Therefore, it is not necessary to cut the branch pipes. This is not an option. Also, you do not need to be afraid of air congestion.

Early opening thermostat

Experienced owners, if the heater does not heat well (Chevrolet Lanos and Zaz Sens), it is recommended to check the regular 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 heater on the Lanos badly heat? Yes, because the temperature of the cooling liquid is not yet sufficient, but it went over the engine through a small gap of the half-open thermostat. Antifreeze gets on the radiator of the stove unheated. This is clearly seen when the machine is still warming up and the thermostat opens for the first time - the supplied air becomes even colder. Much better the stove will heat the interior when the thermostat opens several times.

How to solve the problem of the thermostat?

Owners of these cars recommend buying another thermostat - for example, designed for a temperature of 92 degrees. With this node the motor will not overheat in winter, and the element itself will open on time. In general, with time, early opening sick of any products - therefore, after a while on the "De Lanos" the stove badly heats, and the owner is nervous.

Winter problems

In the winter, the owners of these cars turn to the service station with problems in the work of heating almost every day. Let's try to understand the problem, especially since in this case the reasons are slightly different.

Weak tightness

This is one of the frequent occurrences of the fact that the stove does not heat well (Chevrolet Lanos is no exception). The reason lies in the insufficient tightness of the seams in the ventilation duct and this is manifested most precisely in winter time.

It is checked very easily - if the frost is overboard, the regulator of the heater fan 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 vent box are connected . If in some areas it feels cold, then the salon is cooled by air from the street. Solve this problem by simply smearing the slots with a sealant. To obtain the maximum effect on the damper lever attach the corrugation - the part from the mirror adjustment knob perfectly fits.

Cold air ducts

Before you get into the radiator of the heater, air passes a long enough path in the duct system. In winter, the walls of the air duct are substantially cooled and lower the temperature of the air in the cabin. Inside it becomes very cold. To solve this problem, the ducts are insulated with any heat-insulating material (for example, splen). These works are recommended to be performed after the problem with tightness has been solved. The process is not difficult, but you may need to dismantle the panel.

Summary

If the car "Chevrolet Lanos" badly warms the stove, what to do in this case? Thoroughly check the heating system. Problems can hide in the most unexpected places. Well, be sure to enjoy the experience of experienced lanosovodov.
