Warning! The air conditioning system is under constant high pressure. Never disconnect refrigeration lines or remove any system components without first discharging the system. Discharging the air conditioning system must be done by an experienced technician in a car service workshop. Always wear safety glasses when disconnecting refrigeration lines!
When replacing air conditioning system components, a certain amount of replacement refrigeration oil will be required to fill the volume of the new unit. Use only oil suitable for use in R-134a systems (check the container label carefully).
Removal
1. Discharge the air conditioning system in a specialized workshop.
2. Disconnect the negative cable from the battery.
Warning! If the car stereo system is equipped with a security code, make sure you have the correct combination to activate the audio system before disconnecting the battery!
3. Remove the expansion tank of the cooling system (see Section Removal and installation the radiator and expansion tank of the cooling system).
4. Disconnect the electrical wiring from the cooling and air conditioning fans (see Section Checking the condition of the cooling system fans and their switching circuits; replacement of fans). Remove the radiator with the fan assemblies attached to it with their shrouds.
5. Remove the bolts and disconnect the condensing and discharge lines from the condenser. Immediately plug the open ends of the lines and fittings to prevent dirt and moisture from entering the system.

6. Remove the condenser mounting bolts.
7. Remove the capacitor.
Installation
1. Installation is carried out in reverse order.
Note: The sealing rings must be replaced without fail (before installation, lightly lubricate the new rings with R-134a refrigeration oil).
2. Charge the system and check for leaks in a specialized workshop. When replacing the capacitor, add about 25 ml of refrigeration oil to the system.
