If you change correctly and on time air filter in car Daewoo Nexia, the engine will work without interruption, and its resource will increase significantly. In addition, the air in the cabin will become much cleaner, the furnace will work better and stop moving the windows. You should not forget that the polluted filter is the place of reproduction of mold and bacteria.

The term of replacement of the air purifier for any car is individual and depends on those conditions in which the machine is operated. In case you predominantly drive around the city, clean and not dusty roads, you need to change every 15,000-200,000 mileage kilometers. But if the car is operated on the ground rural roads, the replacement period is better to reduce to 6000-8000 kilometers.

The air barrier on Daewoo Nexia is needed to purify the air, which is served in the power unit during operation. An ordinary air purifier is a layer of special paper, which is folded into the harmonica and placed in a plastic rectangular case.

A good air barrier is capable of catching even the smallest particles that are in the air, but during long-term use it is clogged, its throughput is reduced. Subsequently, this can lead to a reduction in power and interruptions in its work. So that this does not happen, you need to change the air cleaner in a timely manner. The process is very simple and any car enthusiast will cope with it.

Air filter location

Air filter in the car Daewoo Nexia is on the left of the engine, if you stand in front of the hood.

The body is fastened with three supports. Inside the case is a filter material. The filter element has a flat rectangular shape and is distinguished by a large filtering surface.

Special tubes are connected to the housing, by means of which air flow occurs.

Instructions for replacement

The replacement of the air barrier, probably, is the simplest work in the car service and even in an inexperienced motorist will take no more than 15-20 minutes.

Instruments

To change Daewo Nexia, we will not need any special tools, only the usual screwdriver, directly the barrier itself and the old pure rag.

Stages

1. First of all, you need to put a car on a flat surface. When you open the hood, the filter box is on the left of the engine in the corner.
2. The sensor is on the lid. To disconnect it, you need to raise the lock.
3. Next, disconnect the intake air duct, release a slightly clamping clamp.
4. Decorate four locks on the lid of the box.
5. Remove it.
6. Remove the old filter element.
7. Rafting wipe the box.
8. We put a new one.
9. We put the lid and latch the clamps.
10. Connect all the nozzles and fasten them.

If you want the engine of your car to work for a long time and smooth, listen to some recommendations of experienced car owners.

• Sometimes you need to extract the filter and brush it from the accumulated dust and dirt. To do this, it is enough to simply shake it or blow with compressed air. Important! This is done in the opposite direction of air movement when the filter element is installed on the engine.
• Sometimes inspect the filter in order to identify possible damage, cracks, scuffs, either just strong pollution. In case of detection of such faults, replace the barrier urgently.
• In mandatory, during the replacement, clean the inner surface of the housing from the dirt and dust on its walls.
• It is impossible to start the motor if the filter housing is removed or if the filter element is removed from it. It may entail dust particles and dirt in cylinders power aggregate And the subsequent failure of these nodes.
• In case the machine is operated in a very dusty area, the filters must be changed more often.

If there is a stove in a heavy frost on a passenger car, for the driver it will not end with nothing, especially if he managed to leave far from home. This applies to all machines, and "Daewoo Nexia" - no exception. Is it possible to avoid breakdowns exist whether typical malfunctions The stoves on "Nexia" and how to eliminate them yourself?

Principle of operation of the heating system "Daewoo Nexia"

The heating system in the car is arranged as follows. The engine of the machine in the process is heated. It uses antifreeze, filled into the cooling shirt of the motor. This liquid heats up with the engine, and heated, goes to the main radiator of the car. From there on the system of nozzles, hot antifreeze enters into a small stove radiator, covered by a small fan. Heat from there through special air duct enters the salon and heats it. In the rear doors of the car there are exhaust holes required for salon ventilation. Through them, excessive heat goes out.

Scheme of the main elements of the heating system at Daewoo Nexia

Here it should be noted one feature heating system "Daewoo Nexia": it can work independently of the air conditioner. Such constructive solutions for passenger cars There are quite rare. The heater "Daewoo Nexia" not only heats the salon, but also prevents brake frost, and it can work with air conditioning. This feature is useful if the driver wishes to reduce the air temperature in the cabin to several degrees without turning off the stove.

Engine heater

The heater electric motor is installed behind the furnace radiator. This compact motor rotates a plastic impeller, creating a continuous flow of air passing through radiator tubes. The engine housing is metallic, inside the rotor with copper winding and the central shaft on ball bearings.

The housing of the electric motor of the stove on "Nexia" is made of instrumental steel

Metallographic brushes tightly adjacent to the rotor electric charge. Engine number in the catalog - 6841SB566905. It is compatible with other Daewoo cars (for example, with Daewoo Espero). Cost - from 5000 rubles.

Vacuum switch heater

Vacuum stove switch on the car "Daewoo Nexia" is located behind the glove compartment. It is this device that is responsible for the opening and closing of the outer air intake damper and the dampers of warm air recycling in the cabin.

The damper on the "Daewoo Nexia" opens using a vacuum switch

It is controlled by the buttons located on the heater control unit. Device number in the catalog - ER200347893. The cost of the vacuum switch in DEU branded stores is from 600 rubles.

Location of the heater fuse

The Safety Block "Daewo Nexia" is under the dashboard, above the pedals of the gas and clutch.

Chimney fuse "Nexia" is in the right lower corner Block: It is green

It is closed by a plastic lid on which there is a sticker with the location of all fuses and relays.

Safety block "Nexia" is located above pedals and closed by plastic lid

The fuse responsible for the heater is in the lower right corner of the block and is indicated as F19.

The fuse responsible for the "Daewoo Nexia" stove is marked with F19

In the same block there is a furnace fan relay used in situations when the stove motor works on low revs.

Major malfunctions of the heating system "Daewoo Nexia"

The reasons why the stove can stop heating the car interior, there are many. We list the most common.

Chimney clogging

The heater radiator, like any other item, comes in disrepair. It usually happens due to use non-quality antifreeze With an abundance of impurities. They form a layer of scale on the tubes of the radiator and its throughput begins to decline. In the end, the fluid ceases to enter the radiator and becomes cold in the cabin, despite the fact that the heater fan works in normal mode. The problem is eliminated by the replacement of the radiator.

In the grid of the radiator "Nexia", a thick layer of scale and dirt is clearly visible

Air plug in heating system

Usually, the breakdown occurs when the tightness of some pipe in the heating system disappears. When air is falling there, the circulation of antifreeze is broken, and it simply does not reach the furnace radiator. The solution is the complete drainage of antifreeze and the subsequent purge of the heating system with compressed air.

Due to the gaps of the duct nozzles in the heating radiator "Nexia", air traffic jams may occur

Vacuum switch breakage

The vacuum switch on "Nexia" - the device is reliable, but the fasteners on which it holds is quite thin and often break. This may lead to the fact that the air intake damper will simply stop opening and normal circulation of warm air in the cabin will break. To eliminate the problem, the driver will have to acquire a new vacuum switch, as the fastening strips are not sold for it.

The destruction of electromotor bearings

As mentioned above, the central shaft of the heating electric motor with an impeller is suspended on two ball bearings, which can eventually collapse over time. If this happened, the driver after turning on the stove will hear the characteristic creak, gradually turning into a loud grinding. You can solve the problem only with the replacement of the furnace electric motor, since the bearings are not sold to it separately.

Bearings on chimney electric motors "Nexia" often fail

The stove does not blow on the legs

Such a breakdown happens when a vacuum switch controlling dampers. After that, the flaps are lowered in the extreme lower position. As a result, hot air access to the feet of the passenger and the driver overlaps almost completely. The problem is solved by removing the glove box and replacing the vacuum switch.

Removing the stove control unit on Daewoo Nexia

Control of the stove and air conditioning on the car is condensed into one control module located on dashboard, to the right of the driver. The buttons of this module fail quite rarely. However, the need to remove the control unit may occur when the vacuum switch is taken, which was mentioned above. There is nothing complicated in the dismantling of the block, and only a flat turning will be needed for work.

Control unit dismantling sequence

To extract a broken device, to produce recommendations of experienced repairmen:

• From the central duct, which is above the control unit, two deflectors are manually removed, then the plastic frame of the air duct driven by two tags is removed.

  Frame and deflectors of the duct "Nexia" removed, there is access to the wires of the control unit

• Looking through the hand through the hole of the central air duct, you need to disconnect all vacuum tubes and flap cables from the control unit.

  After disconnecting the wires, the control unit "Nexia" can be pushed out of scaffolding and extract from a regular location.

• Now the control unit is approaching a flat scolding and removed from his niche.

Replacing the heater radiator by car "Daewoo Nexia"

As mentioned above, the oven radiator on "Nexia" can clog. In addition, it sometimes begins to leak. This happens when its central tubes finally destroy corrosion, resulting from the use of poor antifreeze. Since the regular chimney radiator on the "Daewoo Nexia" is made of aluminum, it is not possible to pour it without special equipment possible. So the car owner remains only one way out: replacement of the node.

Heating radiator replacement sequence

To perform work qualitatively, follow the proven algorithm:

1. All cooling fluid merges from the car. It takes a complete drain that is required for 8-10 minutes, so it is impossible to rush.
2. Next, the nozzles are removed from the radiator. They hold on steel clamps, to attenuate which should be used flat scolding.

   Nozzles are removed from both the expansion tank "Nexia" and from the heating radiator

3. After removing the nozzles of the radiator tube, it is necessary to shut something so that the remnants of antifreeze do not flow into the floor. It is best to do this with the help of pieces of vet.

   Tubes on the oven radiator "Nexia" should be pushing a rag

4. Next weakened steel fastener clamps, holding the cover of the furnace radiator. After that, the housing locks are rejected by hand, and the radiator is removed through motor compartment.

   Remove the radiator of the heater "Nexia" better through the engine compartment

5. A defective radiator is replaced by a new one, after which the heating system is reverse assembly.

Installation of additional furnace pump at Daewoo Nexia

Since the heating system on the brand under consideration has never been the high power, many owners make additional efforts to insulate their car. One way to increase the power of the heater is to install an additional pump. As a rule, the pump from the gazelle is installed.

As an additional pump on "Nexia", the pump from Gazelle is installed

Additional pumping sequence

Device installation procedure: Basic elements that need to be considered by connecting an additional pump on "Nexia"

Now it is necessary to open the hood and find the nozzle coming from the heater to the motor. The hose is cut at the scene of the bend (but it is desirable to overcertrine it with steel clamps before and after the place of the cut, so that the antifreeze does not flow). The ends of the cut pipe are put on an additional pump. Clamps holding antifreeze are removed.

Additional pump "Nexia" successfully connected to antifreeze nozzles, it remains to be powered

Additional pump connected with nozzles is attached to the air conditioner pipe with a plastic clamp. In order for the pump does not flutter the air conditioner tube, it is recommended to put a small piece of thick rubber under it.

Pomp is screwed by a plastic clamp to the nozzle of the "Nexia" air conditioner; the pump relay is best installed on the contact block at the duct

The positive contact that is responsible for including this relay will start to the salon on a separate button (the power to which is most convenient to spend from the ignition lock).

Video: We put an additional pump on Nexia

The heater by car "Daewoo Nexia" is difficult to call the perfect device. The stove is able to deliver a lot of problems to the driver, especially if it is operated for a long time. Fortunately, most of them can be solved on their own without resorting to expert services of the service center.

If in the car of the Daewoo car, the stove stopped to warm - it is necessary to clean the air system and drive the air out. Is not difficult process, and taking advantage of the advice of professionals, you can easily cope with this problem yourself.

Air Helling System

There are liquid, air and combined cooling systems of various parts of the engines. The first is a closed view system, in which heat from the hot engine is carried out using fluid flow. The second, open type, uses the air flow, the third is the synthesis of the previous ones.

In addition to cooling the engine, these systems have another purpose:

• they heat the air in the heating system,
• do not overheat the oil used for lubrication,
• enjoy liquid and air.

Performance of work begins with removal of protection, then heating the engine to the level necessary for work, and turn off. In this case, you do not need to unscrew the plug on expansion tank, Just remove the hose from the heating of the throttle. We'll have to wait a bit to start leak antifreeze, then return the hose to the fitting, and we collect everything that disassembled.

What if the plug remains? Sometimes it happens, although basically the method works correctly. We leave the hose alone, unscrew the plug, then twist again and repeat the entire cycle again.

It is important to comply with security measures. It is necessary to protect their hands from the burn, as antifreeze heats up to the ninety degrees, so do not forget to wear protective gloves.

Third method

There is another way to remove air from the stove. The simplest but not enough effective.

We heat the car on the slide to make the top cover of the radiator with the highest point of the cooling system. In this position, you must remove the same plug, start the motor and heat up to about 90 degrees. When antifreeze goes into the system, it is poured to the desired level. To enhance the flow, increase the rotation of the machine motor. The operation stops when bubbles do not go from the return.

Another modification of the third solution of the problem is how to drive out the air from the stove of Nexia. The car must be put on the slide, the level of inclination of which is thirty degrees. To this end, you can use the departure from the underground parking lot. We put the car to the handbrake and start. Then raise the hood cover, remove the cover from the expansion tank, pour antifreeze above the maximum level. The next step: Raise the speed (for the cable), approximately 3000-3500, the second hand you need to pump the pipe that goes to the stove. Carefully look at the level of antifreeze / antifreeze in the tosel, when you decline, we fill in the tank. The plug will be completely removed when the level of antifreeze becomes stable.

Questions of motorists

Beginner motorists often ask questions how to accurately find a air stopper or not, and how to drive the air from dEU stoves Nexia.

Drivers with experience advise after buying a car to replace antifreeze, especially in the winter. To determine the presence of a traffic jam, you need to test equipment. We begin with the determination of the level of antifreeze or antifreeze, fill up to the maximum. Run the motor and turn on the stove. Ten minutes later, we click the temperature of the main nozzle and the returns, which goes to the stove. If the nozzles have become warm, and the remaining tubes in the cooling system are hot, it means making a radiator. If the nozzles are hot, you can conduct preventive work on the insulation of the furnace.

Sometimes the owners say that - does not blow there. This problem is that the damper that is responsible for the supply of cold and warm air does not fully provide hot air.

Conclusion

Get rid of air traffic jams quite simply, if you know the structure of the car and certain workflows, as well as comply with the security technique. Follow simple advice, not even the most experienced motorist will not break your head over how to drive out the air from the Daewoo stove Nexia.

Ventilation, heating and air conditioning

Ventilation and heating

To regulate the air temperature, the mixing system of cold and hot air is used. This system provides minority air temperature regulation, which is practically independent of the velocity of the car. The intensity of air supply to the cabin is determined by the fan speed. Therefore, if necessary, the fan must be enabled even when the car moves. For heating zone of the location of passengers on rear seat Warm air is supplied by air ducts located under the rug.

Central deflectors

Air can enter the salon through both central deflector. The degree of air supply is regulated depending on the position of the air supply regulator placed between the grids. The direction of air flow from central deflectors can be adjusted at will, both in horizontal and vertical planes using levers that provide tilt and rotate deflectors.

Side deflectors

Air can enter the car interior through the left and right side deflectors.

Flooring nozzles of lateral windows

Cold or warm air comes on blowing both wind and lateral windows of the front doors (mainly in the zones that provide the visibility of the outer rear-view mirrors).

Salon air conditioning system

Ventilation, heating and air conditioning systems are a single functional complex designed to ensure the most comfortable conditions in the car in any season of the year, regardless of the weather conditions and ambient temperature. The cooling unit of the air conditioning system reduces the temperature and humidity of the air, as well as filtering from dust. The heating unit of the heating system provides an increase in air temperature in any operating modes depending on the position of the temperature regulator. The amount of air entering the interior depends on the fan operation mode.

Air conditioner switch

Run the engine, set the desired fan mode using the switch and press the air conditioner's power button. When you turn on the air conditioner, the control lamp will light up. To turn off the air conditioner, press the same button.

It should be borne in mind that air conditioner does not turn on if the fan operating mode switch is in the OFF position or the ambient temperature below 0 ° C.

If the air conditioning system works during the movement of the car on the protracted lines or in the conditions of intensive urban movement, follow the engine temperature. The operation of the air conditioner in this case may cause engine overheating. If the coolant temperature exceeds the allowed value, turn off the air conditioning system.

Air temperature regulator

The switch is designed to control the speed of rotation of the fan. A total of four fan operation modes.

Air distribution regulator

Air Recycling Mode Switch

Press the switch button when driving along a strongly dyed area or in a dense transport stream to avoid the dust and gas-based car in the cabin. This mode can also be useful for rapidly reduce or increase air temperature in the cabin. When the recirculation mode is turned on, the control lamp lights up and enter the outdoor air interior.

To turn off the recycling mode of the air and resume the ventilation of the car, re-press the same button. In this case, the test lamp will go out.

You should not use the air recirculation mode for a long time. This can lead to an increase in air humidity in the cabin and fogging. Movement with swoveling glasses is dangerous, as the visibility is worse and the likelihood of a road accident is increasing.

Maximum Salon Cooling Mode

Air conditioner switch: enabled.

Air temperature regulator: in the blue zone.

Two-level ventilation mode

If the air temperature controller is installed on the middle position (between the blue and red zones), the warmer air will go to the foot location zone, and the colder is in the top of the car's interior.

Air Recycling Mode: Off.

Air distribution regulator :.

Air temperature regulator: optional.

Switch modes of fan operation: optional.

In order to avoid fogging glass in rainy weather, set the air distribution regulator to the plugness position when the cold air is received from the outside (the heater is turned off). The difference in ambient air and windshield temperatures can cause moisture condensation on the inner surface of the glass and the worsening of the car.

If the car was parked in the right rays of the sun, before turning on the air conditioner, open the windows and ventilate the salon.

In order to clean the winding glasses from condensate in rainy weather, reduce the air temperature in the cabin, turning on the air conditioner. This reception is useful in the rainy season when air humidity is very high.

When driving around the city with an intense transport stream, the efficiency of the air conditioning system may decrease due to frequent stops and movement of the car at low speed

If the air conditioner is not used for a long time (month or more), it is necessary to include it once a week for several minutes, even in winter. Before turning on the air conditioner, run the engine. The periodic inclusions of the air conditioner contribute to the preservation of the lubrication layer on the components of the compressor and seals, and also extends the service life of the air conditioning system.

The air conditioning system compressor does not turn on if the fan switch is in OFF position or the ambient temperature below 0 ° C.
