10. lnstall in the reverse order of removal. Make note of
these rtems:
) lf 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{ 14 2/3ll.oz,4.93 imp.oz);
the result is the amount of oil you should drain
from the new compressor (through the suction
{itting).
r Replace the O-rings with new ones at each fit-
ting, and apply a thin coat of refrigerant oil
before installing them.
NOTE: Be sure to use the right O-rings for HFC-'t34a (R-134a) to avoid leakage.
. use refrigerant oil (ND-OlL 8: P/N 38897 PR7-
A0IAH or 38899 - PR7 - A01) 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.
. lmmediately after using the oil, replace the cap
on the container, and seal it to avoid moisture
aDsorDt|on.
. Do not spill the refrigerant oil on the vehicle; it
may damage the paint; if the refrigerant oil con-
tacts the Daint, wash it off immediately.
. Do not damage the radiator fins when installing
the condenser fan shroud and the compressor.
. Adjust the Ay'C compressoi belt {see page 22-36J
. Adjust the power steering pump belt (see section
17J.
. Charge the system (see page 22-39) and test its
performance {see Page 22-24).

before installing them.
NOTE: Be sure to use the right O-rings for HFC-
134a (R-1344) to avoid leakage.
a Do not damage the radiator and condenser fins
when installing the condenser.
o Be sure to install the condenser mount cushions
securely into the holes.
. Charge the system {see page 22-39) and test its
