2. INSPECT COMPRESSOR OIL
(a) When replacing the compressor and magnetic
clutch with a new one, after gradually removing the
refrigerant gas from the service valve, drain the
following amount of oil from the new compressor
and magnetic clutch before installation.
Standard:
(Oil capacity inside new compressor and
magnetic clutch:
225 + 15 cc (7.6 + 0.5 fl.oz.)) - (Remaining oil
amount in the removed compressor and
magnetic clutch) = (Oil amount to be
removed when replacing)
NOTICE:
• When checking the compressor oil level,
observe the precautions on the cooler
removal / installation.
• Because compressor oil remains in the pipes
of the vehicle, if a new compressor and
magnetic clutch is installed without removing
some oil inside, the oil amount becomes
excessive, preventing heat exchange in the
refrigerant cycle and causing refrigerant
failure.
• If the remaining oil in the removed
compressor and magnetic clutch is too small
in volume, check for oil leakage.
• Be sure to use ND-OIL 8 for compressor oil.
3. INSPECT COMPRESSOR AND MAGNETIC CLUTCH
(a) Disconnect the connector from the compressor and
magnetic clutch.
