Do-it-yourself repair of a Chevrolet Lanos stove

In detail: do-it-yourself repair of a Chevrolet Lanos stove from a real master for the site my.housecope.com.

The main function of the stove in the car is to supply warm air to the passenger compartment and maintain the optimum temperature both during driving and during stops. Inside the stove there is a special liquid heated to high temperatures, it is thanks to it that the air heats up. If the tightness of the stove is broken, it will immediately fail, since cold air will begin to pass through. In the Chevrolet Lanos model, this happens relatively often, since the design of the stove for this car is not made in the best way. In this case, we need to replace the Lanos stove. In most cases, the radiator mounts fail, which can lead to the following problems:

malfunction of the thermostat;
leakage of working fluid;
foreign particles entering the radiator.

In order to understand what exactly happened in your Lanos, it is necessary to study the external manifestations of the malfunction. If the problem is in the thermostat, this will be indicated by the arrow on the instrument panel, which does not move even after the engine warms up. If there are spots and a noticeable decrease in the working fluid, the problem must be looked for in the pipeline. A break in the attachment, in turn, will lead to wiggling of the pipes. What to do if the stove fell on Lanos and how to fix it - we will consider in stages.

Repairing a Chevrolet Lanos stove in itself is not so difficult, it is more difficult to access the lower casing. In the standard variation, it is necessary to completely remove the torpedo, which takes a lot of time. However, there is an alternative - to get to the stove radiator from the bottom side by repairing the Lanos stove without removing the torpedo. To do this, you will need to do the following:

Video (click to play).

Remove both front seats;
Remove the pipeline hoses and drain the antifreeze or antifreeze into a separate container;
Loosen the clamp attached to the gearshift lever and unscrew the fastening bolt to the end;
Pull the lever shaft out of the link assembly. To make it easier for yourself the process of reassembling, mark the connection point of the axis and the node with a marker.

All these manipulations will add some workspace to us. However, the repair of the stove, or rather, its dismantling will be possible only after you remove the metal fasteners from the sides. These are the parts with which the floor and the console are connected.

IMPORTANT! Removing the Lanos stove should be done exclusively with a cold engine.

Next, we proceed to dismantle the lowest casing. Step by step, this process looks like this:

We unscrew all the screws of the casing. Since this will have to be done from the bottom side, you will need a special ratchet and an elongated head by 7. There are 8 of these screws, more precisely, 10, but since it is very difficult to remove the 2 that are near the motor partition, we will remove exactly 8. We unscrew it one by one. In parallel with this, we disconnect the cigarette lighter.
Remove the cover. The radiator is in front of us. Tip - By removing the glove compartment, you will provide yourself with a wider viewing angle.
We remove the latches and take out the heater from the holes. At the top, the case is held by a latch, at the bottom you will also need to unscrew the self-tapping screw.

ATTENTION! The top latch is attached to a fragile plastic bar. Try to be careful not to break it.

The body is assembled exactly the opposite - from item 3 to item 1. Let's clarify that the standard Lanos stove mounts, which are installed during the production of a car, fail very often. If possible, they should be strengthened on their own by making parts from a regular sheet of metal. During assembly, it is very important to avoid any gaps.Ideally, sealants should be used, especially at the joints. The body of the Lanos stove itself should also be checked for leaks before reassembling. Here the compressor will help us, with the help of which an air stream is supplied to the structure with plugged pipes. Working pressure - 0.1 MPa. The cushions of the lower supports, if they are excessively compressed or hardened, will also need to be replaced.

If the car is equipped with air conditioning, repairing the Lanos stove with your own hands will require several additional operations. Specifically, it will be necessary to remove the drain fitting through which the condensate comes out. This fitting is located in the area slightly to the left of the branch pipes. The part can be "identified" by the rubber hose in the shape of the letter G. The fitting will prevent us from removing the casing, since we will not be able to pull the latter towards us and, as a result, push it downward, removing the fasteners from the grooves.

The best solution to how to remove the stove on Lanos in such a situation would be to use a grinder or a hacksaw for metal. We cut off the choke as much as we can. After that, we remove the casing and cut the rest of the fitting. There is no pressure inside the choke, so all these processes do not pose any danger. At the end of the process, in order to save time, the best option would be to replace the fitting with your own hands with a regular tube of the corresponding diameter, which will also effectively drain the condensate.

We hope that this information has given you an idea of what the replacement of the Lanos stove looks like. If you have any advice of your own on how to repair this structure, share it with other motorists. Together we can always find the optimal solution to any of the problems.

The best prices and conditions for the purchase of new cars

Very often, many Lanos car owners are faced with such a problem as poor interior heating, which is especially relevant on the approach of the cold season. It becomes obvious that it is necessary stove radiator repair.

There can be many reasons for the need for such a repair, but in this case the problem is caused by the fact that the stove radiator has fallen off the mount, which is also indicated by the backlash of the outgoing pipes.

So, this video examines the removal and cleaning of the stove radiator without removing the torpedo with your own hands.

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.

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 the power unit is warmed up and the coolant (coolant) temperature 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 the engine compartment into the passenger compartment. 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.

Depending on the car model, the air temperature in the cabin is regulated in different ways - with an adjusting valve, fan speed and the position of the air dampers. The heated air flow is regulated and distributed in different directions. By directing warm air to the windshield and front side windows, you can prevent fogging. With the help of the flaps, you can direct the air to the area of the legs, face and to certain places in the side windows. Windshield blowing 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 high 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 of the heating system for a particular car model.

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 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 temperature of the air flow.
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.

The heating system of the Chevrolet Lanos interior can operate in various 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.

The heater is controlled by the following switches and controls located on the center panel.

Inlet air temperature regulator.
Fan operating mode regulator.
Air flow distributor handle.
Rear window heating switch button.
Slider that controls the fresh air flap 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.

Since all elements of the heating system are interconnected, it is sometimes quite difficult to find out the cause of the malfunction. Similar symptoms can occur for a variety of 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.

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 locksmith 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 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.

For Chevrolet Lanos, a stove radiator from the Chevrolet Sens model is suitable, 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, it is quite simple to repair and replace the radiator of the stove of a Chevrolet Lanos car, consistently following the instructions of professionals. All you need is free time and a standard set of plumbing tools.If during the operation of the Chevrolet Lanos car you are faced with the problem of poor stove operation, do not rush to go to the service center. Replacing the radiator and setting up the heating system can be done with your own hands without large financial and time costs. The main thing is to find the problem in the system and fix it using step-by-step instructions.In the Lanos model, the stove is located under the central part of the torpedo. The device supplies warm air to the passenger compartment, thereby maintaining a comfortable temperature while driving or parking a car. The air is heated by the circulation of a working fluid with a high temperature; the entire system must be completely sealed and not damaged.Unfortunately, the design of the stove itself is not very reliable. Most often, the radiator mounts break, which leads to the passage of cold air. The nominal temperature drops and even with the extreme position of the regulator, cool air blows. Known issues include the following:

the radiator is clogged;

leakage of working fluid;

malfunction of the thermostat.

Determining damage in the pipes is quite simple. If spots appear and the amount of working fluid in the expansion tank decreases, you need to completely inspect the pipeline. If the low efficiency of the heating system is associated with an inoperative thermostat, then the arrow on the instrument panel will be in the extreme position even with a warm engine.

The heater radiator heats up the air that is supplied to the passenger compartment

Advice: before starting repairs, try to exclude all possible factors that affect the operation of the stove. This will allow you to pinpoint the cause of the problem.

The main difficulty faced when repairing a stove is access to the lower casing. For the classic dismantling of this element, you will need to remove the entire torpedo, which will take quite a long time. Pulling out the radiator is easier and faster if you work from the bottom.First, we do the preparatory work:

For convenience, we remove both front seats.
We remove the pipeline hoses and drain the working fluid into a previously prepared container. We remove the branch pipe and drain the working fluid from the heating system
We loosen the clamp that holds the gearshift lever, and completely unscrew the mounting bolt. We unscrew the bolt and remove the clamp for the subsequent dismantling of the lever
We pull out the axle of the gear lever from the traction unit.

We now have free space to work with. But in order to remove the radiator itself, you will need to dismantle the side metal elements that connect the floor and the console.

Remove the side mounts that connect the console to the floor

The bottom cover can now be removed:

We unscrew the 8 screws of the heater casing. This is not easy to do, you need a special wrench (ratchet and an extended head by 7), since you have to work from below. To remove the casing, you will need to unscrew 8 bolts
We remove the casing and get access to the radiator.
We open the latches and take out the heater from the grooves.

The assembly takes place in the reverse order. It is worth noting that factory radiator mounts often break down and it is better to modify these elements from scrap materials. You can use products made of sheet metal with a diameter of 2 mm.

Metal mount holds the radiator well and does not break

Tip: When assembling, all elements must be set in place and securely fastened so that there are no gaps. Insulating materials can be used at the joints. Otherwise, the stove will not work efficiently.

Replacing the radiator in models with air conditioning is somewhat more difficult. It's all about the condensate drain fitting, which interferes with the removal of the heater. There are two ways to solve this problem:

By applying physical force, pulling the casing towards you and lowering it down.

Cut the union with an ordinary hacksaw for metal.

Such events should be carried out at your own peril and risk. But if everything is done carefully, then the casing will not receive critical damage, perhaps the edges are slightly deformed.To replace the radiator of the stove in Lanos, it is not necessary to completely remove the torpedo. You can carry out repairs from below, simply by removing the front seats and the gearshift lever. Using the instructions, you can replace the heater with your own hands and save on car service services.If you have been driving Lanos for several years, then you know what problem he has with the heating system. I bought Lanos a couple of years ago and am well aware of its shortcomings. The stove heats here very badly, and sometimes does not heat at all. I must say that many Lanos growers have such a problem, which means that manufacturers do not want to solve this problem and, probably, forget in which country the car is operated. After all, there are almost six months of frost here.Although the car is cheap and I agreed on the lack of special comfort, but I want it to be warm in the cabin! There are many options on the Internet on how to make a Lanos stove heating. but if a person is not very well versed in technical terms, then it will be difficult to extract something useful from this information. I offer you a simple and effective option, which I performed myself, on my car.First, we will need to properly glue the temperature control dampers. After that, you will have to modify the fasteners of the stove radiator. Then we change the standard thermostat to a "hotter" one, plus we also install a remote thermostat. Replace the expansion tank return hose and stove radiator hose.We install a jet in the heating return of the throttle valve. Then it will be necessary to insulate the engine compartment and interior. We flush the entire cooling system, including the stove radiator and install an electric pump from the Gazelle. If you do all this, then the cabin of Lanos will be much warmer. And you need to start work in the summer, so as not to suffer from the cold in the winter.In fact, Lanos is adapted for Russian conditions, you just need to put a hand in its modernization and then there will definitely be no problems. Last winter showed me how warm and comfortable it is. Of course, I was modifying not only the heating system, but also the engine with suspension, but the presence of heat in the car gives me the desire to upgrade something further. Although, some Lanos owners have no problems with the heater and, I hope, you are one of them.Why does the Chevrolet Lanos stove not heat well? We eliminate the reasons ourselves 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 not heat well? and how to eliminate sabotage on its part, we will describe below.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 warm, 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.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 the nose lifts at least 20 °, twist the plug from the expansion tank and gas it several times - the plug should disappear.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 the fact that they are 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. From the side of the engine compartment, a thick steel wire is wrapped in a circle of pipes near their very base and stretches down the body near the right (on the passenger side) of the spar - there the crankcase protection is fixed. When the pipes are pulled down, the stove itself moves up; The cover between the front seats is removable; With a Phillips screwdriver with a "seven" head, 3 screws are screwed together, the lower distribution cap is removed, which is responsible for redirecting warm air to the legs; The 6 bolts holding the bottom box are removed. Its front part is lowered down; A metal strip (preferably aluminum) is taken 8 cm long, 1.5 - wide and 3 mm thick. It bends like an old doorknob. A hole with a section of 7 mm is drilled in it, through which a bolt with a solid thread is inserted and fixed with a nut with a nylon stopper. A sleeve with an external thread and a sufficiently wide washer is screwed behind it; A hole is made in the lower box - a diameter of about 9 mm - in front of the front wall of the radiator and strictly in the center; With clamping tweezers, the created structure is pushed inside, and the end of the sleeve that appears from the outside is fixed with a nut; The retaining plate is similarly oriented parallel to the radiator tank and by rotating the end of the bolt, located outside, abuts the radiator.

Is the stove blowing with either cold or lukewarm air? Sooner or later, every motorist faces such a problem. The stove, like any other part of the car, cannot last forever, sometimes it requires replacement or repair. Replacing the Chevrolet Lanos stove is a procedure, although not difficult, but not always necessary, because why buy a new one if you can repair the old one?

If you have already decided that the stove needs to be changed, that it cannot be repaired, then you need to buy a new one, or look for and buy a used one, but a working one. We certainly recommend buying a new one. So you will have a guarantee that you will not have to change it in the near future? How to replace? Here's a replacement for a Chevrolet Lanos stove video:

Take a look and do the same.The main reason why the stove does not work is a faulty radiator. We will talk about this now.First you need to remove the front passenger seat, then disassemble the plastic tunnel on the floor. These actions will make it possible to remove the gearbox drive together with the lever. But before removing, do not forget to loosen the clamps on the gearbox pull under the hood. Next, we go back to the salon and unscrew the bolts securing the gearbox lever. As a result, you will be able to pull out the entire mechanism completely.This clamp must be loosenedNow we unscrew the four bolts and nuts in order to remove the sidewalls intended for attaching the console to the floor.And we take out the casing for the distribution of air flows.Flow distribution housingFrom this moment, the most difficult thing begins! You will need to unscrew all the screws securing the heater shroud. Only he closes access to the radiator. It is held by as many as ten screws! The screws holding the shroud near the motor bulkhead are extremely difficult to unscrew. Below there is a photo of the cover already removed, on which all the fastening screws are marked.After unscrewing the screws, you need to remove the casing. But there are also nuances here. If your car is without air conditioning, then there will be no problems, but if the stove is replaced on a Chevrolet Lanos with air conditioning, you will have to tinker a lot, because the condensate drain from the air conditioner interferes with removing the casing. Here you have two options for solving the problem. First, cut the fitting with a hacksaw for metal and calmly remove the casing. The second is less vandal, but no easier to implement. You will have to use all your strength, that is, at the same time lower the casing and pull it towards you. It is advisable that someone help you with this. This is all that differs the replacement of the radiator of a Chevrolet Lanos stove with air conditioning from a model with a poorer complete set.After completing all of the above steps, your gaze will open the very same heating radiator, for the sake of which all this was done. After replacing the radiator, you need to assemble the entire structure extremely carefully so that there are no gaps left.And here's another video for you on replacing the stove radiator on a Chevrolet Lanos video:
