• Diagnostics, refueling and repair of the Mitsubishi Lancer X car air conditioner

A car air conditioner is a fairly reliable device that maintains a certain temperature in the car interior. This unit operates in difficult conditions - sharp temperature changes, constant exposure to vibrations and other factors dramatically reduce the service life of some parts and components of the air conditioner. Therefore, the repair of car air conditioners is a fairly popular service.

The specialists of the technical centers of the JapAuto company provide a full range of services for diagnostics, repair and refueling of Mitsubishi Lancer X autoconditioners. All work in the technical centers of JapAuto begins with diagnostics - the repair of air conditioners is no exception. Diagnostics with the help of special equipment indicates problems - refrigerant leaks, malfunctions of HVAC units.

Most often, repairing an air conditioner consists in restoring the tightness of the unit. This problem can be solved in two ways. The first way is to install new spare parts instead of out of order parts, the second is to eliminate the depressurization using argon-arc welding and powder-plasma spraying.

Our specialists will repair Mitsubishi Lancer X car air conditioners of any complexity. We carry out repair and manufacture of highways, manufacture of rear air conditioner circuits. We refurbish evaporators and condensers using argon arc welding and powder spraying.

Our masters carry out disinfection of evaporators, replacement of bearings and complete repair of compressors of automobile air conditioners. Also here you can flush the air conditioning system, purchase spare parts for the repair of units of this type, buy new and used compressors.

One of the most difficult cases is a compressor breakdown. In this case, most often it is necessary not only to change this entire unit, but also to carry out a number of additional procedures - to replace the receiver-dryer and flush the entire system.

After graduation renovation works the unit is being refueled. Before refueling, an additional check of the tightness of the cooling system is carried out. To check the tightness, use special equipment- leak detector. Also, the check can be carried out using a vacuum. The air conditioner is examined, the parameters of its operation are measured, after which the refueling itself is already carried out, which usually takes no more than half an hour.

Refueling of Mitsubishi Lancer X car air conditioners is carried out by our specialists with particular care - the operation of the entire cooling system depends on the correct refueling. If the pressure in the system after refueling is increased, the air conditioner may fail, if the unit is underfilled, then its operation will be ineffective, therefore, when refueling, it is necessary to strictly follow all the manufacturer's recommendations.

Work aimed at restoring the working capacity of climatic equipment requires large financial costs. To avoid them, it is recommended to diagnose the unit at the technical center at least once every two years. It is also recommended to turn on the device for a short time and in winter time too - this will help to avoid some breakdowns.

Mitsubishi Lancer X car has established itself as a modern reliable vehicle... The operation of the car air conditioner is not satisfactory. However, like most systems, it requires maintenance and timely maintenance.

The main reasons for extraordinary repairs are:

ATTENTION! Found a completely simple way to reduce fuel consumption! Don't believe me? An auto mechanic with 15 years of experience also did not believe until he tried it. And now he saves 35,000 rubles a year on gasoline!

• damage to the integrity and malfunction of the radiator of the Lancer X air conditioner;
• failure of the air conditioner compressor bearing;
• the need to refuel and clean the air conditioning system;
• decrease in compressor performance;
• depressurization of the system;
• malfunction of the pressure and temperature sensors of the air conditioning control system;
• the climate control unit does not work;
• damage to electrical wiring.

Causes and elimination of malfunction of the main units of the Lancer 10 air conditioner

The cause of the malfunction may be damage to the radiator structure due to the ingress of foreign objects, parts of a broken fan blade, or a traffic accident.

When choosing and buying a radiator, you need to pay attention to the conformity of the design of the joints of the air conditioning system pipes installed in the car.

The original radiator of the Lancer 10 air conditioning system is quite expensive. Restoration of the integrity of the radiator structure is possible only in case of minor damage. It is cheaper to replace with non-original models. The table shows the approximate cost of the original and the radiator and its counterparts from various manufacturers.

Manufacturer	vendor code	approximate price
Termal	1760614	RUB 2 800, 00
Luzar	2069556	RUB 4,800.00
AVA	737280	RUB 5,000.00
Nissens	349017	RUB 6,000.00
Mitsubishi original	7812A165	RUB 25,000.00

Check the conformity of the standard sizes and seats on the official website of the manufacturer.

The choice of a specific model of air conditioner radiator depends on the material resources. If you plan to produce self-replacement radiator, it is better to make a choice in favor of a non-original model, especially since it is not difficult to replace the radiator technologically.

Compressor bearing failure

The compressor bearing in the air conditioning system is under constant mechanical stress. In this regard, it wears out quickly enough, especially since it is not located in better conditions exploitation. Key signs of wear:

• extraneous high-frequency sound in the area of ​​the compressor;
• mechanical knocking;
• heating of the compressor during operation.

If the first signs of bearing wear appear, it must be replaced. Sequence of work on replacing the bearing:

The cost of analogs of bearings Lancer 10 1.8 B ranges from 400 to 1,000 rubles. Some models from different manufacturers are shown in the table.

Manufacturer	The code	Description	Price, rub
Cargo	250129	35x55x20	450
SNR	ACB35X55X20		600
Febest	WF35550020		750

In some models of compressors, the standard size 35x50x20 can be installed, so before purchasing a bearing, dismantle the unit.

Refueling the air conditioning system

The air conditioning system requires periodic refrigerant charging. Lancer X official service centers fill the air conditioner with refrigerant HFC-134a, 480-520 grams of bulk density.

Refueling is necessary in the following cases:

• violation of the tightness of the system after repair;
• loss of refrigerant during long-term operation, leaks;
• if necessary, carrying out routine maintenance.

If the air conditioner control unit detects a value less (or more) than the critical value using the pressure sensor in the system, it gives a signal to block the engagement of the air conditioner clutch. Thus, if the system is not charged correctly, the air conditioning system will not work. For high-quality refueling, special equipment is required, the presence of appropriate certificates. Self-refueling is not recommended.

Cleaning the evaporator of the air conditioner

It is carried out when foreign odors appear in the passenger compartment when the system is switched on. You can do it yourself special means, For example:

Bacteria can accumulate in the condensate drain container, which helps to destroy this agent. Better to pour this product inside drainage system through the drain hole. Good illumination is required to inspect cavity contamination.

Elimination of errors of the air conditioner control unit

To eliminate errors in the control unit, it is necessary to carry out computer diagnostics. After fixing and decoding the error code, you should not immediately change the sensors or other devices that the scan shows. It is necessary to check the serviceability of the electrical wiring of the air conditioning system according to the diagram. For this, it is better to use the services of an auto electrician.

Timely and high-quality service of the air conditioner system is a sure guarantor of its constant performance.

Mitsubishi Lancer 10. Heater and air conditioner - part 2

Compressor 7 (Fig. 12.3) is installed on the engine and is driven by a poly V-belt to drive auxiliary units. Compressor of axial piston type, variable capacity. The compressor shaft is installed in an aluminum casing on two needle

bearings and sealed with an oil seal on the side of the drive pulley. The compressor has seven pistons with Teflon O-rings. Lobe type valves. The capacity regulator is integrated into the compressor housing. Drive pulley installed

on a double-row ball bearing and with the engine running, it constantly rotates. When the air conditioner is turned on, the torque from the pulley to the compressor shaft is transmitted through a friction clutch with an electromagnetic drive. Compressor

circulates the refrigerant through the system and builds up the pressure required to allow refrigerant to flow through the expansion valve opening.

Condenser 5 multi-flow type is installed in front of the radiator of the engine cooling system. The honeycomb is made of flat, thin-walled aluminum tubes with internal longitudinal baffles to ensure rigidity. Aluminum tanks with flanges for connecting pipes. The tanks are divided into sections according to their height. Passing through the condenser, the refrigerant flow changes direction several times. In the condenser, the vapors of the refrigerant compressed by the compressor are condensed, and the heat generated during this is removed to the ambient air.

Receiver-drier 3 is installed on the left side of the condenser. The body of the receiver-drier is made of aluminum alloy. Inside there are a filter element and a cavity filled with desiccant granules (silica gel). The liquefied refrigerant passing through the receiver is cleaned of possible impurities of dirt and moisture.

Thermostatic valve 12 of the block type is located under the hood near the engine panel, has flange connections... The pressure of the compressed refrigerant after passing through the throttling hole in the valve body drops sharply - it begins to boil. A regulating element is installed in the valve body that changes the flow area of ​​the throttling hole depending on the pressure and temperature of the refrigerant.

The evaporator 11, located in a common housing with a heater, is made of aluminum tubes with fins to improve heat transfer. Passing through the tubes of the evaporator, the boiling refrigerant actively absorbs heat from the air blowing over the outer ribbed surface of the tubes. The air is cooled and the fan 10 is supplied to the passenger compartment.

The elements of the air conditioning system are interconnected by pipelines into a single sealed circuit. The pipelines are made of aluminum alloy. To connect the moving elements of the system, pipelines in some sections are equipped with flexible inserts made of synthetic materials. In places of connections individual elements systems installed o-rings round section made of neoprene. The pipelines also have two service valves 4 and 9 for connecting the diagnostic and filling equipment... The valves are closed with screw caps to keep dirt out.

Rice. 12.3. Schematic diagram air conditioning systems: 1 - combined pressure sensor; 2 - pipeline section high pressure; 3 - receiver-dryer; 4 - service valve of the high pressure line; 5 - condenser; 6 - fan of the condenser and radiator of the cooling system; 7 - air conditioner compressor; 8 - pipeline section low pressure; 9 - service valve of the low pressure line; 10 - heater fan; 11 - evaporator; 12 - thermostatic valve

It is forbidden to press the spools of the service valves in order to check the presence of refrigerant in the system!

The pressure sensor 1 of the combined type is installed on the section of the high pressure pipeline in the engine compartment. The sensor forcibly turns off the air conditioner compressor when the system is depressurized (pressure is less than 0.17 MPa, or 1.7 kgf / cm2 and in case of an emergency increase in pressure in the system)

system (pressure is more than 2.5 MPa, or 25 kgf / cm2 in order to protect the compressor from overloads. At a pressure of 1.7 MPa (17 kgf / cm?), the sensor turns on the power supply circuit of the fan 6 of the engine cooling radiator, as a result of which condenser and the pressure in the air conditioning system decreases.

The system is charged with R 134a refrigerant. A special oil has been added to the refrigerant to lubricate the compressor.

Notes (edit)
When the air passing through the evaporator is cooled, the water vapor contained in it condenses. Across drain tube condensate is drained under the vehicle underbody. At high humidity ambient air under the car may form a puddle of water - this indirect sign serviceability of the air conditioning system.

In connection with specific features repair of the air conditioning system (see the warning above) in this subsection only works on the removal and installation of the control unit for the ventilation, heating and air conditioning system are described, since to remove the remaining elements of the heating and air conditioning unit (including the heater radiator), complete removal is required node from a car with depressurization of the air conditioning system.

Replacing the filter for the air entering the passenger compartment is a routine maintenance job and is described in Sec. 4 "Maintenance" (see "Replacing the cabin filter ventilation systems, heating

And air conditioning ", p. 81).

Everyone knows what an air conditioner is and what functions it performs. The air conditioner is one of the components of the driver's comfort while driving. In this article, we will talk about what malfunctions a Mitsubishi car air conditioner can have and how to refuel it.

[Hide]

Common breakdowns

So, what malfunctions are typical for the climate control systems of the Mitsubishi Pajero CL, Lancer 10 or other models:

1. Leaky tubes. Aluminum tubes over time, Lancer 10 or Pajero XL become unusable as a result of rust. However, in this regard, not only tubes are brought in, but also other components car air conditioner eg rubber gaskets and seals. As a result of long-term operation, as well as exposure to various temperatures and careless assembly and disassembly, the seals can harden. But, as a rule, it is the pipes of the climate control system that leak on the Pajero XL or Lancer 10. In addition to the pipes, the problem of lack of tightness can lie in the cracks that form on the compressor. To prevent this, regularly inspect all elements of the system and change the tubes in time.
2. Defective compressor or radiator. Such a breakdown is one of the most unpleasant, since it entails large labor and material costs. As a rule, problems associated with a radiator or compressor on the Pajero XL, Lancer 10 or any other Mitsubishi model are associated with depressurization and lack of proper maintenance. If the car owner does not pay attention to diagnosing and checking the system in time, then dust and moisture can get into it, which leads to corrosion. Failures in the operation of climate control can be associated with insufficient cooling of the radiator. If the radiator fan fails, first of all you need to check the contacts - they may have oxidized. But if everything is in order with the radiator fan, it is possible that dirt has accumulated between the radiators, which prevents the system from functioning normally.
3. Electrical breakdowns. If the air conditioner Lancer 10 or another model does not work, it may be due to electrical faults... Typically, in this case, again, it comes about contacts. They oxidize, rot, so from time to time it is necessary to diagnose and replace them.
4. Obstruction of the system. In some cases, the air conditioner on Lancers 8, 9, 10 does not work for this reason. Usually we are talking about a thermostatic expansion valve - dirt can simply get there. Flushing can solve such a problem in the functioning of the air conditioner - as a rule, after that the climate system works normally.
5. The pressure is too high. It may appear as a result of too much freon poured into the system or from too weak cooling of the radiator.
6. Inoperative air dampers or clogged cabin filter element. Often owners of Lancers 10 and other Mitsubishi models with air conditioning are faced with this. It happens that the climate control works properly, but cold air does not enter the passenger compartment. There is a possibility that this is due to a breakdown of the air damper actuator.
7. Problems in the operation of the climate control unit. In principle, if problems have arisen with the "brains", then it will not be possible to solve them without equipment. Such a malfunction will be solved only by flashing the unit.

How to fill with your own hands?

To refuel with your own hands, follow these steps:

1. Put on gloves to start. Depending on the refueling kit you will be using, reassemble following the instructions in the instructions.
2. According to the service book for your car, you need to find a hole in the low pressure system. Usually the pipe that comes with the refueling kit is only suitable for this outlet, so you should not be mistaken. In Mitsubishi, the high pressure port is different in shape from the low pressure port.
3. Before opening the hole, thoroughly clean the area around it. This is to prevent accidental trash from entering the system.
4. Next, connect the refueling kit hose to the hole found.
5. Put the car on the parking brake, engage the neutral speed. Start the engine and carefully, slowly, unscrew the valve of the can of freon for refueling. Sit in the driver's seat and gasp a little - this will allow consumable in the most optimal way to disperse through the system. Gas until you feel that cool air has appeared in the cabin from the air dampers. Then just shut off the engine and unscrew the charge hose.

The request returned an empty result.

Be careful, the filling of the household and car air conditioner is different. The car air conditioner is filled with oil, different freons. Experts recommend changing the dryer at least once every two years, otherwise the compressor will fail, it will drive off the aluminum shavings and you will still have to flush the system. It is better to do it with specialists!
