NOTE:

Depending on the condenser manufacturer, the receiver/dryer version is different. On some versions for example the receiver/dryer is integrated in the condenser. The integrated receiver/dryer has a dryer cartridge that is no longer available as a replacement part. Therefore, if there is a complaint regarding a vehicle with a condenser with an integrated receiver/dryer, it may be necessary to replace the entire condenser after correcting the complaint. Refer to the Parts Information and Refrigerant Circuit (vehicle-specific Service Information).

Condensers with an integrated receiver/dryer or dryer cartridge that cannot be replaced separately or is not available as a replacement part, the condenser must be replaced after flushing (with the dryer cartridge installed). Refer to Refrigerant Circuit (vehicle-specific Service Information) and the Parts Information.
