Quite often, the owners of this model have to find out why the Chevrolet Lanos stove does not heat well. At first, we note: the heater works great, without any complaints from the owner. However, after the season, problems begin, traditionally identified with the onset of cold weather.
It is dangerous to put up with them 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 view, and their constant scrubbing distracts from the road, which is fraught with hit into an accident. It is urgent to deal with the heater, and I would like to - at no extra cost. First of all, you need to find out what caused his abnormal behavior.
Why does the Chevrolet Lanos stove heat up badly? and how to eliminate sabotage on its part, we will describe below.
Coolant and problems with it
There may be 2 options:
The coolant is not picking up the desired temperature... The most common culprit for this is the thermostat: it breaks down quite easily. It is not difficult to identify it in this capacity: firstly, when the engine is warmed up, the coolant temperature gauge crawls extremely lazily to the right place, and it stops without reaching the desired mark. Secondly, you can touch the pipes connecting the radiator and thermostat. In the event of a malfunction of the latter, they either heat up almost instantly (the stove is up to 70 ° C, according to the devices, is not yet heated), or they will remain cold. There can be only one repair here: replacement of the thermostat.
An article on the topic "".
Weak coolant flow through the radiator... It is also determined by touch: the outlet and inlet hoses have a sharp temperature difference (although it can be observed for other reasons). One of the factors causing a drop in coolant pressure in the system is channel blockage. In this case, you can try flushing the radiator. The simplest way is considered to be the way in which the pipes are removed, the pump is connected, and with the help of a bucket, the flushing solution is chased in a circle. If the matter is not in clogged channels, but directly in the radiator, it will have to be repaired or changed.

Airing the radiator can also hinder the circulation of the coolant - it cannot break through. Symptoms are the same as in the previous paragraph. The treatment is most simple: drive your Chevrolet Lanos up a hill so that your nose lifts up at least 20 °, twist with expansion tank cork and gas several times - the cork should disappear.
Individual feature
Probably, only this model has a tendency to break off the radiator mount, which is a bracket that presses it to the air duct. After such an incident, cracks appear, and cold street air begins to flow into the cabin, bypassing the heated radiator. You can check the assumption by moving the radiator pipes under the hood - they must be stationary, otherwise you have the indicated situation.
Chevrolet orders the removal of the torpedo to eliminate the accident. However, many owners complain: such actions, in addition to being laborious in themselves, often lead to problems with the reverse installation of removed elements. The complaints about the return of the air ducts are especially strong. Craftsmen have developed a technique that makes it possible to dispense with a minimum of dismantling.
The new stove heats up perfectly, but during operation, the fastener often comes off - a bracket that presses the radiator of the cabin stove to the air duct. As a result, unheated, cold air begins to flow into the formed slots, bypassing the radiator. The efficiency of the car's heating system drops from 50% to 90%. They also happen as a breakdown option: a clogged stove radiator or the thermostat does not close completely. Any of the cases is easily diagnosed, for example, if the radiator of the stove is clogged, then in the engine compartment, the inlet pipe will be hot, and the outgoing pipe will be cold or barely warm. In case of violation thermal conditions engine operation due to the fault of the thermostat, it is enough to visually analyze the coolant temperature indicator on the instrument panel, after the engine warms up, the arrow does not rise to the middle for a long time. In the event of a break in the radiator mount (bracket), the easiest way to check is by swaying the stove pipes from the engine compartment. As you might guess, the wiggling of the pipes means that the stove radiator has fallen. In my case, this is exactly what happened, probably after the "good pit", I did not even guess at first, I noticed the disorder only with the onset of cold weather. According to the instructions for troubleshooting, you need to remove the torpedo (instrument panel). But fortunately, by nature, I am very lazy and jealous of the money spent on cars between service intervals. The first solution found in the vastness of the Slavic peoples is the replacement or the ability to fix the stove radiator on Lanos with "some kind of difficult Makar" without disassembling the torpedo. People who described this miracle of action complained about the complex, fragile and flawed assembly process for the stove itself. Broken plastic of the stove body in places. Somewhere you need to specially saw off, and then, when assembling, sit the sawn-off plastic on the sealant. It is difficult to insert the air ducts into place during reassembly, due to the plastic behavior caused by the temperature ...
There should be an easy solution to the problem of fixing the stove radiator. Yes there is! A very quick and easy way to secure a fallen stove radiator back into place is to insert spacers between the radiator and the stove body. To do this, cut out a 10x10 cm hatch in the lower housing of the radiator duct with a hot knife on three sides and fold it down (heating the plastic at the bend). There is no need to completely cut it out, otherwise after inserting the stove spacers, it will be extremely difficult to insert the cut-out plastic of the hatch into place. To treat the fastening of the radiator of the Lanos stove, you will need: a knife, a gas burner (a lighter with a constant torch is suitable), a sealant, a rubber hose (about 30 cm), glue a second.
The photo turned out more clearly, there was a camera at hand mobile phone... For convenient access to the lower part of the radiator, it is enough to remove the lower air duct directing hot air to your feet by unscrewing 3 self-tapping screws. When removing the air duct, the clamping of the wires hanging on the clips will prevent it, one right is enough to pry it out with a screwdriver from the hole. You also need to first unscrew the screws, push back the plastic of the center console, the one between the seats. Move the gearshift lever to the 2nd or 4th gear position, thereby pushing the plastic of the center console as far back as possible.
Heat the knife on a gas burner and simply stick the tip of the blade into the plastic, slowly cutting it along the contour of the intended hatch. Do not push the knife deeply, if you overdo it and insert the blade deep into the air duct housing, you can damage the radiator itself. In the process of cutting the hatch, you will have to repeat the heating of the blade several times, since the knife cools down during the cutting process. The very movement of a red-hot knife in plastic goes like butter. After cutting and bending the hatch, cut off a piece of rubber hose by measuring, making a v-shaped cut on one side with a knife, which will abut against the edge of the radiator reservoir. I inserted a short screw or bolt into the inside of the hose to prevent deformation of the hose itself from high temperature. He filled the remaining internal void of the hose and liberally smeared the segment at the ends with sealant and inserted the resulting spacer between the duct housing (in which the hatch was partially cut out) and the upper part of the stove radiator.

Info tags: the stove does not heat, car stove repair, cold in the car.
A comfortable microclimate in the cabin of any car is maintained by a heating system or a stove. Another function of this system is to prevent the glass from fogging and freezing. The central element of the stove is the radiator. Any malfunction of it can lead to very unpleasant consequences, especially in the cold season.
Functions, device and principle of operation of the stove radiator
The radiator (convector, heat exchanger) of the stove is the most important unit of the interior heating system of any car. The stove ensures the creation and maintenance of a comfortable temperature for the driver. This is especially true during the cold season. In addition, the heater prevents fogging of car windows.
The heating system consists of the following units and parts:
- frame;
- stove radiator;
- heat exchanger pipes;
- control valve;
- fan;
- fan electric motor;
- air ducts and distribution dampers.
The heating system heats up the air entering the passenger compartment
The role of the coolant is played by antifreeze circulating through the cooling system. When power unit warmed up and the temperature of the coolant (coolant) reaches 50 ° C, it can be used to heat the passenger compartment. Depending on the position of the tap, a certain amount of hot antifreeze is supplied to the radiator. The fan directs the air flow from engine compartment to the salon. This air passes through the honeycomb of the radiator, receiving heat from the heated antifreeze. The more antifreeze passes through the heat exchanger, the more heat is transferred to the air. The flow of heated coolant in the radiator can be controlled by a tap.
The radiator of the Chevrolet Lanos stove has a rather simple device.
Depending on the car model, the air temperature in the cabin is regulated different ways- adjusting valve, fan speed and position of air dampers. The heated air flow is regulated and distributed in different directions. By directing warm air to the windshield and front side windows fogging can be prevented. With the help of dampers, air can be directed to the area of the legs, face and to certain places in the side windows. Blowing windshield It is also necessary to create a slightly increased pressure so that dust and dirt from the street does not get into the cabin. Thus, the most comfortable microclimate is provided for the driver and passengers.
The design features of the heater somewhat limit its operation. So, the stove cannot be turned on on a cold engine. Wait until the coolant reaches 50–60 ° C. Otherwise, the engine will warm up much longer, especially in severe frost. In addition, due to the increased humidity in the cabin, the windows will start to fog up. Therefore, water and air heaters are sometimes installed as additional ones. It depends on the design features heating systems specific model car.
Features of the interior heating system Chevrolet Lanos
The device of the Chevrolet Lanos stove is similar to most other car interior heaters. Its design provides for both independent and joint heating of the passenger compartment with air conditioning.
The radiator is installed under the cover of the middle part of the center panel, located between the driver and passenger.
In Chevrolet Lanos, the heater radiator is located under the cover of the middle part of the center panel, located between the driver and passenger.
There is no control valve, therefore, when the engine is running, the antifreeze constantly heats the heat exchanger.
The device and operation of the stove
The heating system of the Chevrolet Lanos includes the following components.
- A damper that distributes the air flow to the passenger compartment or to the glass.
- Upper air distribution flap.
- Stove radiator.
- Air damper that regulates the air flow temperature.
- Air conditioner evaporator radiator.
- Fan with electric motor.
- Damper for changing the air supply mode (position A - recirculation mode, B - outside air supply).
- Lower air distribution flap.
- Air duct for heater and air conditioner.
- Windshield blow-off pipes.
- Side windows blowing channels.
Heating system Salon Chevrolet Lanos can work in different modes
The amount of air entering the heat exchanger is controlled by an air regulating flap (4). Its position determines that part of the air flow that passes into the radiator (3) and heats up. In addition, the fan electric motor (6) also has several modes of operation, increasing or decreasing the intensity of the air flow. Mixing in a certain proportion, heated and cool air creates a comfortable temperature for the driver.
Stove controls
The heater is controlled by the following switches and controls located on the center panel.
- Intake air temperature regulator.
- Fan operating mode regulator.
- Air flow distributor handle.
- Electric heating switch button rear window.
- Slider that controls the fresh air damper and recirculation.
- Air conditioner on / off button.
A comfortable microclimate in the passenger compartment is set using six regulators of the control unit
Fan operating modes are selected independently of the positions of other regulators. The dampers are adjusted using the cables connected to them.
Diagnostics and troubleshooting
Since all elements of the heating system are interconnected, it is sometimes quite difficult to find out the cause of the malfunction. Similar symptoms may occur when different reasons... In the cold season, the main symptom of a defective stove is poor heating - cold or slightly warm air enters the cabin. This can happen for the following reasons.

Replacing the heater radiator
The stove radiator is the main problem of the incorrect operation of the Chevrolet Lanos interior heating system. The easiest way to solve this problem is to replace the radiator. The work is quite complicated, labor-intensive and expensive. When replacing a radiator, specialists in a car service completely disassemble the dashboard in the cabin.
However, the work can be done with your own hands, without removing the dashboard. This will require a viewing pit or overpass and the following tools:
- a set of wrenches and caps;
- Phillips and slotted screwdrivers;
- stationery knife;
- glue "Moment";
- platypuses.
To replace the radiator, you will need a standard set of plumbing tools
The device and fastening of the stove body does not depend on the presence of an air conditioner in the car. Therefore, for all Chevrolet Lanos models, the procedure for replacing the stove radiator is the same.
Installing a new or washed stove radiator is performed in the reverse order.
The radiator can be replaced in another way. To do this, you will need to remove and remove the dashboard from the passenger compartment. This operation can be done on your own in half an hour without removing the front seats. The torpedo is removed from the passenger compartment along with the stove body, opening access to the elements of the interior heating system.

Choosing a new heater radiator for Chevrolet Lanos
For Chevrolet Lanos, a stove radiator from Chevrolet models Sens, which has the same dimensions. Heat exchangers with strip or plate cooling fins are available. In addition, on the market you can find strip-plate prefabricated and tubular-strip brazed aluminum radiators of such manufacturers as NISSENS, AVA, NRF, DAC, GROG, KMC with the number of trunk pipes from 16 to 22. The cost of products can vary greatly depending on design, workmanship and manufacturer.
Thus, repair and replace the stove radiator Chevrolet car Lanos, consistently following the instructions of professionals, is quite simple. All you need is free time and a standard set of plumbing tools.
I have been doing copywriting for 6 years, for the last 4 years I have chosen this direction of work for myself as the main one. I have an impeccable command of Russian, I know English at an intermediate level. During this time, thousands of texts have been written on a variety of topics.
I have been using Daewoo Lanos for the first year, or rather the first winter, and faced the problem that the stove does not heat well, or rather, one might say it does not heat at all. I would like to clarify this a common problem this car, or specifically, that something is wrong with my Lanos.
Answer:
In general, the design of the stove Daewoo lanos not quite bad and in most cars it does not cause problems. In case it is poorly or not served at all warm air into the passenger compartment, obviously the problem exists in the heater control unit. To make sure that the diagnosis is correct, I recommend removing the unit with regulators and checking the cables that go from the control handles to the dampers. Most likely this is the problem. Also check the electric motor of the stove, whether it works in all modes, it happens that due to a breakdown of the switch, the motor runs at minimum speed and warm air is poorly supplied to the passenger compartment. In addition, some Lanos owners are faced with the problem of loosening the fastening of the stove motor, due to this, its fan does not supply the entire portion of air to the cabin, therefore, stove Daewoo Lanos does not heat well.
The reasons why the Daewoo Lanos stove does not heat well. Video
After all, it is much more practical to warm the already warm air than cold air from the street. Otherwise, I would not put it back in any way.
lost heat in Lanos what to do how to fix it? Thanks. | # but as before ...
But hypothetically, this is useful:
The expander at this time was barely warm. With it, the engine will not overheat, you do not need to worry about this, because the thermostat will begin to open at degrees Celsius. Then he pulled both front seats out of the passenger compartment and put a fan heater in the passenger compartment - an ordinary home one, from an outlet.
Most owners try to flush radiators and mains with phosphoric acid solutions, descaling agents, even Coca-Cola. And sometimes these methods help, but more often rinsing does not work. As a result, the Lanos 1.5 stove is not an exception anyway. In a garage or at home, the process of flushing the stove radiator is carried out using three lengths of hose and a warm solution of citric acid.
In addition, antifreeze test can be performed under these conditions. 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. The radiator is clogged from the 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 time - a decrease in the flow force cannot be noticed immediately.
It is best to check the flow strength against a healthy model. The heater radiator, and with it the evaporator for the air conditioner, are easily clogged with various debris - it can be fluff, leaves, whatever.
Move the gearshift lever to the 2nd or 4th gear position, thereby pushing the plastic of the center console as far back as possible. Not a tricky tool Warm up the knife on a gas burner and just stick the tip of the blade into the plastic, slowly cutting it along the contour of the intended hatch.
Do not push the knife deeply, if you overdo it and insert the blade deep into the air duct housing, you can damage the radiator itself. The very movement of a red-hot knife in plastic goes like butter. After cutting and bending the hatch, cut off a piece of rubber hose by measuring, making a v-shaped cut on one side with a knife, which will abut against the edge of the radiator reservoir.
I inserted a short screw or bolt into the inside of the hose to prevent deformation of the hose itself from high temperature. Because my family flew in a closed state in the cold - and I stupidly threw him out of his regular place after drinking a liter of wine and freezing in the process, and it was necessary to disassemble a half-drive of the timing belt, then I drove without a thermostat for a while. And later I plugged in a remote thermostat with valve motor Nexia. I bought Luzar rubles for something - plastic, non-separable ... Well, okay!
Whether this gave more heat to the stove - I did not understand. Because the thermostat is at least just now - and this is better than when it is not there: But I am for simplicity, for convenience. And for removing, as far as possible, all unnecessary "Opelcadet" constructive jambs from the car. Here are a couple of links on the topic: Moreover, in summer and autumn everything was still bearable.
Until the cabin smelled of antifreeze ... And two days later the windows began to sweat so much that neither the air conditioner nor the heated rear window helped. The stench became stronger, the heat from the stove went even less ... And all this - on the first snow, the first cold weather at the end of October. It all ended in general with a steam of antifreeze from the grilles on the dashboard!
Then I unhooked the hoses from the stove and started driving without a stove at all. In the meantime, I ordered a replacement radiator: The very design of the stove radiator mounts fails. High temperatures, low quality plastic and serious stress lead to the fact that the fixing bracket wears out, and the radiator gradually breaks off from the duct.
It is not difficult to imagine that then cold air enters the interior through the cracks. Here, as your stove will not try, there will be a glacier in the cabin.
Poor tightness
From there, some of the coolant heats the throttle, and the rest helps to heat the passenger compartment. This section has two obstacles that prevent the coolant from flowing normally: A hole comes out of the fitting that is too small for the coolant to exit. The location of this nozzle is the area of the first nozzle. A plastic tee on the back of the engine turns the coolant 90 degrees.
At the same time, the pump does not differ in special performance.
Consequently, after passing such obstacles, the coolant flows through the radiator at a lower speed. Therefore, the Chevrolet Lanos does not heat well the stove.
If, in front of the tank, a restrictor in the form of a cylinder with a diameter of ten millimeters, a length of 10 to 15 millimeters and a hole of 3 millimeters is placed in the throttle heating return hose, then the amount of coolant passing through the radiator and its speed will slightly increase. In this case, the limiter, if possible, is best made of stainless steel. In this case, an increase in the amount of coolant will occur through the radiator of the stove, but through the throttle heating system, its amount will slightly decrease, because the diameter of the standard limiter is 4 millimeters.
Regardless, throttle heating will be fine. The standard thermostat reads 86 degrees Celsius, but it often allows the coolant to pass through earlier, at about 80 degrees. This is because the thermostat fully opens at 86 C. Consequently, the coolant of normal temperature has not yet passed through the entire engine, but the thermostat has already opened and the coolant flow has gone into a small slot even before it is fully opened.
That is why it turns out that the Lanos stove does not heat well, because the coolant enters the stove subcooled. This reason is well manifested at the moment the engine warms up, when the first opening of the thermostat occurs, the air blows from the diffusers colder than before. The stove will work much better after several openings of the thermostat, because by that time the coolant will warm up to 87 degrees Celsius, and the fan of the main radiator will sometimes turn on.
To prevent the thermostat from opening early, you can set another one with a mark of 92 degrees Celsius.
With it, the engine will not overheat, you do not need to worry about this, because the thermostat will begin to open at degrees Celsius. Over time, any thermostats begin to open earlier, far from reaching the required temperature - accordingly, the stove begins to heat less and less. Partial passage of cold air past the stove radiator.
When the air flow is directed by the damper to the radiator or past it, the direction is incompletely overlapped, which leads to a partial ingress of cold air into the duct behind the radiator, which is insufficiently heated. Cool air begins to blow out of the diffusers, as cold air mixes with heated air.
The position of the lever determines the closing of the damper. The air duct from which it comes out is located in the glove compartment area on the left side. It is possible to get to it, but at the same time it is rather inconvenient.
But it's funny just because then the stink in the cabin will be like in the cabin of a LiAZ bus! Or maybe someone has no oil leaks, no antifreeze, no exhaust under the hood. Remove the stove radiator once and fix it normally. Swinging - it means that the mount fell apart for me, it was not obvious, I somehow had no idea to check it.
In my case, replacing the radiator was, of course, forced.

I admit that this is not always necessary. But it's better to put good radiator, to be sure.
Heat in Lanos part two
Doing once is okay to do it! Native radiators are shit. They are aluminum ... And my flow along the junction of one of the tubes with the wall to which the tank is attached. You can't trust her to anyone. Yes, in the service, to the heap, they will probably be reconnected for the removal and installation of a torpedo.
And if they break any plastic, they will keep silent, so they will collect it. Nothing complicated, this is the first time I've done such a job. Good luck to everyone on the roads and warm cars!
