11. Install in the reverse order of removal. Make note of
the following items.
If you're installing a new compressor, drain all
the refrigerant oil from the removed compressor,
and measure its volume. Subtract the volume of
drained oil from 140 m
the result is the amount of oil you should drain
from the new compressor (through the suction
fitting).
Replace the O-rings with new ones at each fitting,
and apply a thin coat of refrigerant oil before
installing them.
NOTE: Be sure to use the right O-rings for HFC-
134a (R-134a) to avoid leakage.
Use refrigerant oil (ND-OIL 8) for R-134a DENSO
piston type compressors only.
To avoid contamination, do not return the oil to
the container once dispensed, and never mix it
with other refrigerant oils.
Immediately after using the oil, reinstall the cap
on the container, and seal it to avoid moisture
absorption.
Do not spill the refrigerant oil on the vehicle; it
may damage the paint; if the refrigerant oil con-
tacts the paint, wash it off immediately.
Adjust the A/C compressor belt (see page 22-85).
Charge the system (see page 22-89), and test its
performance (see page 22-76).
The PCM memory must be reset after reconnect-
ing the battery (see page 11-125).
Enter the anti-theft code for the radio, then enter
the customer's radio station presets.
