Remove the bolts. and disconnect the discharge line
and the condenser line from the condenser.
NOTE: Plug or cap the lines immediately after dis-
connecting to avoid moisture and dust contamina-
tion into the system.
DISCHARGE LINE
Remove the two mounting bolts, then lift out the
condenser as shown.
NOTE: Do not damage the radiator and condenser
fins when removing the condenser.

Install in the reverse order of removal. and:
. if you're installing a new condenser, add refriger-
ant oil (ND-OIL 8: P/N 38899 - PR7 - A01) (see
page 22-21t,.
. replace the O-rings with new ones at each fitting,
and apply a thin coat of refrigerant oil {ND-OIL 8:
P/N 38899 - PR7 - A01) before installing them.
NOTE: Be sure to use the right O-rings for HFC-
134a (R-134a) to avoid leakage.
a do not damage the radiator and condenser fins
when installing the condenser,
. 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 24!.

A/G System Service
Evacuation
Only use service equipment that is U.L.-listed and is cer-
tified to meet the roquirements of SAE J2210 to remove
HFC-134a (R-134a) lrom the 8ir conditioner system.
CAUTION: Exposulo to 6ir conditioner refligorrnt and
lubricani vapor or mi3t crn i.ritato 9y33, noaa and
thrort. Avoid bratthing ths .ir conditionor rsfrigorrnt
snd lubricsnt vtpor or mist.
lf accidental system discharge occurs, ventilate work
area before resuming service.
R-134a service equipment or vehicle 8ir conditioner sys-
tems should not be pressure tested or leak tested with
compressed ait.

1. When an Ay'C System has been opened to the atmo-
sDhere, 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 be
replaced.l
2. Connect a R-134a refrigerant Recovery/Recycl-
ing/Charging System to the car, as shown, follow-
ing the equipment manufacturer's instructions.
NOTE; lf tow pressure does not reach more than
93.3 kPa (700 mm Hg, 27.6 in'Hg) in 15 minutes,
there is probably a leak in the system. Partially
charge the system and check tor leaks {see Leak
Test).

1. Connect a R-134a retrigerant Recovery/Recycling/
Charging System to the car. as shown, following
the equipment manufacturer's instructions.
NOTE: Be sure to install the same amount of new
refrigerant oil back into the A/C system before
chargtng.
2. Open high pressure valve to charge the system to
about 98 kPa (1.0 kgf/cm', 14 psi), then close the
supply valve.
3. Check the system for leaks using a R-134a refriger-
ant leak detector with an accuracy of '!4 g {0.5 oz)
per year or better.
4. 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.
5. Aiter checking and repairing leaks, the system must
be evacuated (see System Evacuation gn page 22-
38).
