(b) Remove the 3 bolts and the w/pulley compressor assy.
9. INSPECT COMPRESSOR OIL
(a) When replacing the w/pulley compressor assy with a new one, after gradually \
removing the refrigerant gas from the service valve, drain the following amount of oil from the new w\
/pulley compressor assy
before installation.
Standard:
(Oil capacity inside new w/pulley compressor assy: 90 + 15 cc (3.0 + 0.5 fl. oz.) ) ± (Remaining
oil amount in the removed w/pulley compressor assy) = (Oil amount to be r\
emoved when replac-
ing)

NOTICE:

When checking the compressor oil level, observe the precautions on the cooler removal/instal-
lation.

Since compressor oil remains in the pipes of the vehicle, if a new w/pulley compressor assy
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 w/pulley compressor assy is too small in volume, check for
oil leakage.

Be sure to use ND±OIL 8 for compressor oil.
