1. ADJUST COMPRESSOR OIL
(a) When replacing the cooler compressor assembly with a new one, gradually discharge the inert gas (helium) from the service valve, and drain
the following amount of oil from the vents indicated by the arrows in the illustration before installation.
HINT: The drain bolt and washer can be reused.
Standard:
(Oil capacity inside a new compressor and pulley: 130 + 15 cc (4.6 + 0.51 fl.oz.)) - (Remaining oil amount in the removed
compressor and pulley) = (Oil amount to be removed when replacing the compressor)
NOTICE:
-
If a new compressor is installed without removing some oil, due to the oil remaining in the pipes of the vehicle, the oil amount will be too
large. This prevents heat exchange in the refrigerant cycle and causes refrigeration system failure.
-
If the volume of oil remaining in the removed compressor is too small, check for oil leakage.
-
Be sure to use ND-OIL 8 or equivalent for compressor oil.
2. INSTALL COMPRESSOR AND PULLEY
(a) Install the bracket with the bolt.
(b) Using an E8 "TORX" socket, install the compressor and pulley with the stud bolts.
