BMW X5: Instructions For Opening And Replacing Parts In Refrigerant Circuit
WARNING:
- Avoid contact with refrigerant and refrigerant oil.
- Follow safety instructions for handling R 134a refrigerant.
- Follow safety instructions for handling refrigerant oil.
CAUTION:
- Always use new O-rings each time A/C connections are opened.
- Moisten O-rings with refrigerant oil prior to fitting.
- Seal all parts to be returned at openings to prevent ingress of
moisture or foreign bodies.
I. Opening refrigerant circuit without part replacement, as preliminary
work to further work
(e.g. engine removal):
Work sequence:
- Draw off A/C system, then determine drawn-off refrigerant oil quantity.
- Carry out main work.
- Replace removed refrigerant oil with new refrigerant oil.
- Evacuate and fill A/C system.
II. Part replacement and part replacement on account of insidious leak
(minor leak, e.g. hairline crack)
Work sequence:
- Draw off A/C system, then determine drawn-off refrigerant oil quantity.
- Carry out part replacement
- Replace removed refrigerant oil with new refrigerant oil
- Additionally replenish new refrigerant oil in accordance with replaced
parts:
- Compressor: refer to NOTES ON REPLACING COMPRESSOR
- Evaporator: 10 ml
- Condenser: 10 ml
- Desiccant insert / desiccant bottle: 30 ml
- Each replaced refrigerant line: 10 ml
- Condenser with integrated dryer: 30 ml
- Safety pressure switch and seals: no additional refrigerant oil
- Evacuate and fill A/C system.
III. Part replacement on account of sudden leak
(major leak, e.g. pipe break due to accident)
Work sequence:
- Draw off A/C system, then determine drawn-off refrigerant oil quantity.
- Carry out part replacement.
- Replace removed refrigerant oil with new refrigerant oil.
- Additionally replenish 25 ml new refrigerant oil and new refrigerant oil
in accordance with
replaced parts:
- Compressor: refer to NOTES ON REPLACING COMPRESSOR
- Evaporator: 10 ml
- Condenser: 10 ml
- Desiccant insert / desiccant bottle: 30 ml
- Each replaced refrigerant line: 10 ml
- Condenser with integrated dryer: 30 ml
- Safety pressure switch and seals: no additional refrigerant oil
