IMPORTANT:
I. Part replacement as preliminary work fur further repair work and part
replacement based on gradual leakage
(minor leak, e.g. hairline crack)
Procedure:

- Carry out part replacement
- Replace removed refrigerant fluid and additionally top up with new
refrigerant fluid according to
components replaced:
- Compressor: refer to NOTES ON REPLACING COMPRESSOR
- Evaporator: 10 ml
- Capacitor: 20 ml
- Desiccant insert/dryer flask: 20 ml
- Each replaced refrigerant line: 10 ml
- Capacitor with integrated dryer: 40 ml
- Safety pressure switch and seals: no additional refrigerant fluid
- EVACUATE AND FILL A/C system
