5. Install in the reverse order of removal, andl
install the field coil with the wire side facing
down (see above).
clean the pulley and compressor sliding surfaceswith non-petroleum solvent.
check the pulley bearings for excessive play.
make sure the snap rings are in the groove prop-
efly.
apply locking agent to the threads of the center
bolt, and tighten it securely.
make sure that the pulley turns smoothly after
it's reassembled.
Relief Valve Replacement
Recover the refrigerant with Recovery/Recycling/
Charging System lsee page 22-221.
Remove the relief valve and the O-ring. Plug the
opening to keep foreign matter from entering the
system and the compressor oil from running out,
NOTE:
. Do not let the compressor oil run out.
. Make sure there is no foreign matter in the sys-
tem.
RELIEF VALVE13.2 N.m (1.35 kgf.m,9.76lbtft)
3. Clean the mating surfaces.
4. Replace the O-ring with a new one at the relief
valve, and apply a thin coat of refrigerant oil (ND-
OIL 8: P/N 38897-PR7-A01AH or 38899-PR7-A01)
before installing it.
5. Charge the system (see page 22-39), and test itsperformance (see page 22-241.

these items;
. lf you're instslling a new condenser, add refriger-
ant oil (ND-olL 8: P/N 38897-PR7-A01AH or 38899- PR7 - A01) (see page 22-211.
. 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-
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
performance (see page 22-241.

A/C System Service
Evacuation
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 svstem.
CAUTION: Exposure to air conditioner refrigerant and
lubricant vapor or mist can irtitate eyes, nose and
throat. Avoid breathing the air conditioner refrigerant
and lubricant vapor or 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.
!@@l some mixtures ot air and R-t3ita have
been shown to be combustible at elevated pressures
and can result in fire of explosion causing injury orproperty damage. Never use compressed air to pressure
test R-134a service equipment or vehicle air conditionet
svstems.
Additional health and safety information may be obtained
from the refrigerant and lubricant manufacturers.
When an A"/C Svstem has been ooened to the atmo-
sphere, such as during installation or repair, it must
be evacuated using a R-134a refrigerant Recovery/
Recycling/Charging System. (lf the system has been
open for several days, the receiver/dryer should bereplaced, and the system should be evacuated for
several hours.)
Connect a R-134a refrigerant Recovery/Recycling/
Charging System to the vehicle, as shown, follow-
ing the equipment manufacturer's instructions.
NOTE: lf low pressure does not reach more than
93.3 kPa (700 mm H9,27.6 in.Hg) in 15 minures,
there is probably a leak in the system. Partially
charge the system, and check for leaks (see Leak
Test).

@ 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

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.
R€frigerani capacity: 700 1o g 124.7 llroz)
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
HFC-134a (R-134a) from the air conditioner system.
CAUTION: Exposure to air conditioner r€frigsrant and
