Note: Radiator catalog number (capacitor) air conditioner see here.
Capacitor: A – receiver-dryer
The right side of the condenser has a built-in receiver-dryer, which has a filter for cleaning the refrigerant from impurities.
Condenser (air conditioner radiator) multi-flow type is located in front of the engine cooling system radiator. It is attached to the radiator tanks of the cooling system using brackets. The condenser honeycombs are made of flat thin-walled aluminum tubes with internal longitudinal partitions for rigidity and external fins to improve heat exchange. Aluminum tanks with flanges for connecting pipelines. The tanks are divided into sections along their height, so when passing through the condenser, the flow of refrigerant changes direction several times. In the condenser, the condensation of the refrigerant vapors compressed by the compressor occurs and the heat released during this process is removed into the surrounding air.
When the air conditioner is turned on, the engine control unit turns on the power supply circuit of the electric fan of the engine cooling radiator, which improves heat exchange in the condenser and reduces the pressure in the air conditioning system.

Recommendations
At least once a year, preferably before the start of summer operation, wash the fins A of the condenser honeycomb from adhering dirt, dust and anti-icing reagents B. This will improve heat exchange, reduce the pressure in the system and increase the service life of the system elements.
Do not use high-pressure water jet cleaners to clean the condenser. This may result in damage to the thin-walled fin plates. Even with regular cleaning, the need to replace the condenser arises much more often than you would like. The fact is that it is the first to receive the flow of anti-icing reagents, dirt and pebbles from the road. And the walls of its tubes are thin... In most cases, the condenser is damaged by corrosion in the third or fourth year of operation.
If the condenser's seal is damaged due to corrosion, it will be more expensive to repair it. Even if the argon welding master manages to patch the hole, a leak may soon appear in another place. By the way, the pressure in the system on hot days can reach 25-28 bar.
In addition, the complex structure of the condenser tube should be taken into account: it is divided into channels by partitions along the length, so there is a high probability that after welding some of the channels will be blocked. Accordingly, the dissipated power will drop and the air conditioner will perform worse, especially in traffic jams and in hot weather.
After each experiment with patching the condenser, you will need to pay for removal and installation, welding of the condenser and filling the system with refrigerant. So it is better to install a new condenser immediately. Instead of an expensive original one, it is quite possible to buy a cheaper condenser from authorized manufacturers of spare parts.
You can replace the air conditioner radiator yourself, but if you do not have special equipment, it is better to have the subsequent air conditioner refilled at a service station.
Removal
Place the vehicle in the work area (or a two-post lift), apply the parking brake and disconnect the ground wire terminal from the battery (10 mm spanner).
Drain the refrigerant from the vehicle's air conditioning system (see here).
Note: If the system is depressurized due to through corrosion of its parts, then there is no need to discharge it.
Raise the vehicle to a height convenient for performing the work.
Remove the front bumper (see here).

Having lifted the capacitor on the right side, we remove the capacitor bracket from the holder on the radiator of the cooling system. Similarly, we bring out the bracket from the left side of the capacitor...
Remove the capacitor from the vehicle.
Installation
Before installation, add compressor oil to the condenser in the amount according to Table 5-1 (compressor oil Sanden SP-10, measuring container).
Place the capacitor into the opening of the radiator frame and install its supports in the mounting points in the radiator body, Figure 5-3 (flat head screwdriver).
Remove the plugs from the pipelines and the condenser, install new sealing rings on the pipelines. Apply Sanden SP10 compressor oil to the sealing rings.
Replace the tube sealing rings with new ones.
Connect the pipes to the condenser fittings and secure with bolts, Figure 5-2.
Tightening torque of pipeline fastening bolts - 8 Nm (0.8 kgf·m) (replaceable head 13, ratchet and extension, torque wrench).
Install the air deflector, Figure 5-1.
Install the front bumper.
Perform a vacuum degassing of the air conditioning system and load the system with refrigerant (refrigerant R134a, loading rate - 475±35 g).
Check the air conditioning system for refrigerant leaks (leak detector).
Check the operation of the air conditioning system.
