pulley/overload safeguard. If no bulges are visible on ribbed belt pulley/overload safeguard, it may yet be possible that the A/C compressor has
locked-up. Another indicator is abraded rubber material in the area of the ribbed belt pulley.
‹› The A/C compressor is equipped with a protected oil supply, this prevents A/C compressor damage in the event that the system is empty. This
means that approximately 40 to 50 cm of refrigerant oil remains in the A/C compressor.
‹› The engine may only be started when the refrigerant circuit is installed correctly. 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
‹› A/C Compressor Regulator Valve (N280) is not activated when the refrigerant circuit is empty and the A/C compressor idles with the engine.
‹› If it is necessary to start the engine with a discharged refrigerant circuit:
‹› Refrigerant circuit must be fully assembled.
‹› At least 1/4 of the prescribed refrigerant oil must be in the A/C compressor.
‹› No not rev engine higher than 2000 rpm.
‹› Let the engine run only as long as is absolutely necessary, maximum 10 minutes.
Note the following when starting engine for first time after filling refrigerant circuit:
Start the engine with the A/C compressor switched off ("ECON " on or "AC" off) and wait until the idling speed stabilizes.
Open an instrument cluster vent.
Select temperature preset "Lo" on A/C Control Head (E87).
Now switch A/C compressor on ("Auto" mode) and allow engine to run for 5 minutes at idling speed.
‹› Make sure alignment bushings - 3 - are seated correctly.
‹› Pay attention to notes for installing A/C compressor. Refer to => [ A/C Compressor ] See:
