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

ChargingLeak Test
Use only service equipment that is U.L.-listed and is cer-
tified to meet the requirements of SAE J2210 to remove
HFC-134a (R-134a) from the air conditioner system.
CAUTION: Exposure to air conditioner refrig6rant and
lubricant vapol or mist can irritate eyes. nose and
throat. Avoid broating the air conditione. relrigerant
and lubricant vapor o; mist.
lf accidental system discharge occurs, ventilate work
area before resuming service.
R-134a service equipment or vehicle air conditioner sys-
tems should not be pressure tested or leak tested with
compressed air.
@ some mixtures of air and R-1348 have
been shown to be combustible at €levat€d pre3sures
and can rosult in fire or explosion causing iniury or
property damage. Never use compressed air to pressure
test R-134a s€rvics oquipment or vehicle air conditioner
Systems.
Additional health and safety information may be
obtained from the refrigerant and lubricant manufac-
rures.
Connect a R-134a refrigerant Recovery/Recycling/
Charging System to the vehicle, as shown in the pre-
vious column, following the equipment manufactur-
er's instructions.
NOTE: Be sure to install the same amount of new
refrigerant oil back into the A/C system before
charging.
Open high pressure valve to charge the system to
the specified capacity, then close the supply valve,
and remove the charging system couplers.

Check the system for leaks using a R-134a refriger-
ant leak detector with an accuracy of 14 g (0.5 oz)
per year or better.
lf you find leaks that require the system to be
opened (to repair or replace houses. fittings, etc.),
recover the system according to the Recover
Procedure on page 22-22.
After checking and repairing leaks, the system must
be evacuated (see System Evacuation on page 22-
38).
JUse only service equipment that is U.L.-listed and is cer-
tified to meet the requirements of SAE J2210 to remove
