REFRIGERANT LINES, DISCONNECTING AND CONNECTING AT A/C COMPRESSOR, Vehicles with 2.0L: Notes
The A/C compressor without an A/C Clutch -N25- is always driven when the engine is running. If the vehicle has an A/C compressor without an A/C Clutch -N25-, then the vehicle may only be started when the refrigerant circuit has been properly assembled. For example; if the refrigerant lines are not connected to A/C compressor, when the engine is running the A/C compressor may heat up (via internal heat generation) so much that the A/C compressor will be damaged. Such internal heat generation results from the fact that - even with delivery near 0% - the A/C compressor is confronted with a fixed resistance (sealed circuit).
An A/C compressor with an A/C Clutch -N25- is installed as a running change on certain 4-Cylinder vehicles from MY 2012. Refer to BELT PULLEY, REMOVING AND INSTALLING, A/C COMPRESSOR WITH A/C Clutch -N25- . The A/C clutch turns off the A/C compressor drive completely under certain conditions (for example "ECON"). The correct Climatronic Control Module -J255- version must be installed and coded correctly so that the A/C Clutch -N25- can be activated by the Climatronic Control Module - J255- display and control head. Using the Vehicle Diagnostic Tester in the "Guided Fault Finding " function.
Close open lines and connections on A/C compressor using suitable caps (to prevent possible penetration of dirt and moisture).
