REFRIGERANT LINES, DISCONNECTING AND CONNECTING AT A/C COMPRESSOR, Vehicles with 3.0L and 3.2L: Notes

NOTE:

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).

Close open lines and connections on A/C compressor using suitable caps (to prevent possible penetration of dirt and moisture).

The following procedure describes removing and connecting of the refrigerant lines on a vehicle equipped with a 6 cylinder TDI engine. Vehicles with a 6-Cylinder gas engine, may have a few differences, but the refrigerant lines are removed and installed in the same manner.
