Now you need to install a ball valve, and you need to find a convenient place for it, since with the onset of the warm season of the year, you will have to turn off the additional heater.

The valve is installed on the direct supply hose of the second heat exchanger. We mount the frill.

This completes the modernization of the Nexia heating system. Now the car interior will be warm even in the most severe winter. Among all the features of carrying out the procedures described above, it is necessary to note the possibility of their independent implementation without any experience. renovation works.

I plugged it in, everything works ... but the wires are warming up near the stove motor, which is normal. Disconnected the additional pump, they are also warming up. So it is not because of the pump that they warm up.

How to install an additional pump in the heating system of Daewoo Nexia

I did not give an additional load to the motor wires. Found a hole that would lead the wire into the salon. We cut the hose at the bend, preliminarily clamping the branch pipe before and after the cut so that the antifreeze does not drip.

We put on the pipes on the pump, remove the previously worn ties. We attach the pump itself to the ties to the air conditioner tube. Hoses should be connected to the radiator sockets, tightening them well with clamps. Next, it is necessary to glue the entire perimeter of the additional heat exchanger installed in the system with foil-clad isolon.

This will reduce heat loss due to the fact that the radiator will not give it to the nearby metal elements. Using tees, we connect the hoses of the additional radiator to the hoses of the main heat exchanger.

To do this, in any most convenient place, the main main hose is cut and a tee is inserted, on one of the sockets of which there is a hose coming from the additional heat exchanger. The connections of all hoses are well tightened with clamps.

The valve is installed on the direct supply hose of the second heat exchanger. We mount the frill. See also: How to fix a leak in the heating system of a private house. This completes the modernization of the Nexia heating system.

Our country has always been famous for its harsh winters. In this regard, many owners of Daewoo Nexia have to experience constant discomfort while driving a car in the cold season, since the interior heater simply cannot cope with its work and cannot provide a comfortable temperature. For this reason, most motorists resort to various technical tricks and modernize the stove. The most acceptable option for tuning the interior heating system is an additional pump for the Nexia stove, since the pump provided by the design cannot fully perform its functions, providing unsatisfactory circulation of antifreeze, due to the increased length of the pipes.

In the design of the machine heater, an additional pump is installed on the branch pipe through which the antifreeze circulates, in series with the main one and strengthens it. The pump drive is connected through a stove resistor. Due to this, the additional pump will be turned on when the maximum position of the temperature regulator is set on the stove control panel, and will continue to work when it is further switched to a lower position.

Such modernization of the heater allows the car interior to warm up much faster. As car owners note, after it is carried out, warm air from the deflectors begins to blow at a warm temperature power unit up to about 50 degrees. As for the pump itself, you can install a part of both domestic and foreign production on a car. Despite the differences in design and price, they will work equally well.

In the case of carrying out such a procedure as installing an additional radiator for the stove, it is necessary to mention its disadvantages:

1. A car with an additionally installed heater heat exchanger will not have a cabin filter.
2. We'll have to sacrifice a recirculation flap.

Let's talk about how to independently install an additional stove radiator on the Nexia. Before carrying out this procedure, it is necessary to purchase the heat exchanger itself (an element from the VAZ-2109 is suitable), a ball valve, hoses, 2 tees, clamps, a piece of foil isolon and a tap fitting.

Let's describe the sequence of self-assembly of an additional radiator:

• Having opened the hood, it is necessary to dismantle the frill in the area of \u200b\u200bthe right windshield wiper.
• We remove the recirculation damper, which we no longer need, and in its place, previously closed with foil isolon, it is necessary to install an additional radiator.
• A small podium must be built for the new heat exchanger. Due to this, the air will blow over it well, constantly warming up by the heat of the heated coolant inside the channels.
• The lower part of the installed radiator must be laid with a sealant. This will help to block the access of cold air to the heat exchanger.
• Hoses should be connected to the radiator sockets, tightening them well with clamps.
• Next, it is necessary to glue the entire perimeter of the additional heat exchanger installed in the system with foil-clad isolon. This will reduce heat loss due to the fact that the radiator will not give it to the nearby metal elements.
• Using tees, we connect the hoses of the additional radiator to the hoses of the main heat exchanger. To do this, in any most convenient place, the main main hose is cut and a tee is inserted, on one of the sockets of which there is a hose coming from the additional heat exchanger.

• The valve is installed on the direct supply hose of the second heat exchanger.
• We mount the frill.

This completes the modernization of the Nexia heating system. Now the car interior will be warm even in the most severe winter. Among all the features of carrying out the procedures described above, it should be noted that they can be performed independently without any experience in repair work. In addition, the completion of the heater will not take much time, and the effect of the procedure performed will be very noticeable. In addition, an additional pump or stove is not whimsical to maintain, and therefore it is recommended for installation on cars operated in areas with cold climates.

The best prices and conditions for the purchase of new cars

The Nexia stove is not distinguished by good interior heating - in severe frosts, cool air blows from the air duct deflectors, although the stove regulators are set to maximum heating.

By analogy with the installation diagram below, you can install a Bosch pump on the Nexia. It costs more than a Gazel pump, but unlike a Gazel pump, it does not start to leak over time.

Catalog number of the "Bosch" pump for ordering in Exist.ru:

• 0 392 020 024 - productivity is 500 l / hour, the cost is from 1700 rubles.
• 0 392 020 034 - productivity 750 l / h, cost from 1600 rubles.
• 0 392 023 004 - productivity 850-1050 l / h, cost from 2800 rubles.

The branch pipe that goes from the stove to the engine is lifted up, we pass it above another pipe (which goes from the expansion tank). We cut the hose at the bend, preliminarily clamping the branch pipe before and after the cut (so that the antifreeze does not drip).

We put on the pipes on the pump, remove the previously worn ties

I installed the pump turn-on relay closer to the electrical block near the air duct. I took +12 V from the yellow wire on the block to turn on the pump

Plus to turn on the relay (in the diagram, photo No. 2, designated as "to the heater fan") was carried into the salon, and fed through a separate button to the plus from the ignition switch

The result exceeded all expectations! If you are still freezing, I strongly advise. A tangible effect on obtaining maximum heat from the stove will be if you also install a 92-degree thermostat on the Nexia, as well as modify and air the stove. Do not forget also after these procedures to expel air from the cooling system of the Nexia

Owners daewoo cars Nexia sometimes encounter the fact that the stove does not heat well. What problems caused the poor performance of the oven and why in Daewoo Nexia the heater does not heat up? We invite you to consider the main reasons for the lack of heat in the car, as well as find ways to solve them.

• stove radiator;
• fan;
• expansion valve;
• heater fan;
• evaporator radiator;
• nozzles for supplying antifreeze;
• cabin filter.

Removing the stove control unit

The control unit for the heater in the cabin is the panel with levers and switches located on the center console. When dismantling the stove, you will need to remove it. This can be done in a few minutes by following these steps:

How to increase the air flow in the stove

Sometimes car owners are faced with the fact that daewoo car Nexia stove does not blow in the legs. In this case, experienced motorists are advised to disassemble the control unit and find a rubber membrane. It will be damaged, most likely a small hole. The result is that the air is sucked in and cannot move the dampers. The hole should be sealed with any good glue for rubber, let it dry, then assemble the block.

Important! To ensure the simultaneous blowing of the legs and glass, it is necessary to block the damper or its drives in an intermediate position. In the second case, the movement of the actuator is limited to two positions: suction or extrusion. The first provides air flow to the legs, the second to the glass.

In the Nexia car, the stove blows weakly and when its channels are clogged or air bubbles begin to form in the heating system. The easiest way to get rid of them is to turn off the engine, open the expansion tank cap, then manually pour in antifreeze. The clogged channels are cleaned with cleaners for the cooling system and washed for seven to eight minutes.

Additional pump

If at first glance everything is working properly, but the stove is blowing cold air in the Daewoo Nexia car, this means that there is a factory defect. You should not be upset, everything can be fixed by modernizing the stove.

Some motorists install an additional electric pump from a GAZelle on the car; Bosch pumps are also suitable. The pump is installed so that the antifreeze returns from the stove to the engine, then the flow of heating air into the passenger compartment increases.

How to determine the cause of a malfunction

Fuse arrangement diagram

Without experience in servicing a technical device, it is extremely difficult to diagnose the source of a breakdown. For objectivity of the results, contact the workshop.

1. Check the mechanisms for the electrical component: the fan is stationary when the switch is activated, the fan is unstable, jerky;
2. Mechanical reason: Daewoo Nexia stove blows with cold air, insufficient airflow, weak air flow.

For repairs, we install the machine on a flat platform, or on an inspection pit for ease of diagnosis. We fix back row wheel chocks, squeeze the parking brake, move the rocker to the first gear position.

We start the engine, turn on the levers of the stove heating block one by one. By this action, we exclude (confirm) a breakdown in the electrical circuit. Let's assume the fuse is faulty.

We carry out the replacement ourselves, without going to the workshop. In accordance with the data in the operating manual, the fuse responsible for heating is located under the index "F12". We extract it, insert a new one, the work is completed.

The fuse module is located behind dashboard, on the left side. Access from the driver's seat.

Installing an additional pump on the stove

Another way to modify the stove is to install an additional pump. The water pump provides forced circulation of the coolant. The second pump will allow the antifreeze to circulate faster and more intensively to heat the interior.

Installing an additional pump on the stove can take no more than half an hour, so it is quite possible to do this work yourself.

A standard pump is installed as an additional

To install an additional pump you will need:

• the pump itself;
• metal clamps;
• a piece of hose 1 m long;
• a set of screwdrivers and wrenches.

The work is carried out in the following order:

1. A small circle of antifreeze circulation is assembled. For this, the pump is connected to two nozzles. A short piece of hose is connected to the fitting for the antifreeze outlet, and a longer one is connected to the supply fitting.
2. Coolant is drained from the system.
3. Antifreeze hose is removed from the heater radiator.
4. An assembled unit with a pump is connected to the place of the antifreeze outlet hose.
5. The pump is securely fixed behind the cladding panel, the reliability of the fastening of the hoses is checked.
6. IN expansion tank antifreeze is poured.
7. The engine starts and warms up to operating temperature.
8. The joints are checked for antifreeze leaks

Installing a second pump will increase the intensity of heating the passenger compartment.

If a small circle of liquid circulation works without leaks, then the efficiency of the stove will increase significantly. It is recommended to install a second pump on used Daewoo Nexia cars, since due to partial wear of the mechanisms, the stove may no longer cope with its work.

Thus, it is quite simple to diagnose and eliminate the malfunction of the heater of the Daewoo Nexia car on your own. Moreover, without resorting to the services of a car service, you can modify the heating system. In this case, the efficiency of heating the passenger compartment will increase significantly.

Our country has always been famous for its harsh winters. In this regard, many owners of Daewoo Nexia have to experience constant discomfort while driving a car in the cold season, since the interior heater simply cannot cope with its work and cannot provide a comfortable temperature.
