1. Before installing the gearbox, slide the rack all the
way to right.
2. Pass the right side of the steering gearbox above
and through the right side of the rear beam.
3. Hold the steering gearbox and slide the rack all the
wav to the left.
4. Raise the left side of the steering gearbox above
and through the left side of the rear beam.
5. Install the pinion shaft grommet and insert the pin-
ion shaft up through the bulkhead.
NOTE: Align the tab on the pinion shaft grommet
with the slot in the valve bodv.
6. Install and tighten the gearbox mounting bolts.
NOTE: After installing the gearbox, check the air
hose connactions for interference with adjacent
pans.

7.Center the steering rack within its stroke.
Make sure that the cable reel of the SRS is centered
as follows:
. Turn the steering wheel left approx. 150 degrees,
to check the cable reel position with indicator.
. lfthe cable reel is centered. the yellow gear tooth
lines up with the alignment mark on the cover.
. Return the steering wheel right approx. 150
degrees to position the steering wheel in the
straight ahead position.
ALIGNMEi'IT MARK
Slip the lower end of the steering joint onto the pin-
ion shaft (line up the bolt hole with the groove
around the shaft), and tighten the lower bolt.
NOTE:
. Connect the steering shaft and pinion with the
cable reel and steering rack centered.
. Be sure that the lower steering ioint bolt is se-
curely in the groove in the steering gearbox pin-
ion.
. lf the steering wheel and rack are not centeted,
reposition the serralions at lower end of the
steering joint.

NOTE; The original radio has a coded theft protection
circuit. Be sure to get the customer's code number
before- disconnecting the battery.- removing the No.32 (7.5 A) fuse from the under-
hood fuse/relay box.- removing the radio.
After service, reconnect Dower to the radio and turn it
on. When the word "CODE" is displayed, enter the cus-
tomer's 5-digit code to restore radio operation.

Description
Outline
The air conditioner system delivers cooled air into the passenger compartment by circulating refrigerant through the sys-
tem as shown below.
CONDENSOR
This car uses HFC-134a {R-134a) refrigerant which does not contain chlorofluorocarbons Pay attention to the following
service items:
. Do not mix refrigerants CFC-I2 (R-l21 and HFC-134a (R-134a) They are not compatible'
. Use onty the recommended potyatkytenegtycol {PAG) refrigerant oil (ND-OIL 8: P/N 38899-PR7-A01) designed for the R-
134a compressor. Intermixing the recommended (PAG) refrigerant oil with any other refrigerant oil will result in com-
pressor tailure.

. Use a halogen gas leak detector designed for refrigerant R-134a'
. R-.12 and C-l34a refrigerant servicing equipment are not interchangeable. Only use a Recovery/Recyclins/Charging
System that is U.L.-listed and is certifLd to meet the requirements of sAE J2210 to service R-134a air conditioning sys-
rems.
. Always recover the refrigerant R-134a with an approved Recover/Recycling/Charging System before disconnecting any
A,/C fitting.

A/C System Service
Leak Test
Only use 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: Exposura to air condition ratrigerant and
lubaicant vapor or mist can irritato oyes. nose and
throat. Avoid br€athing tho sir conditionsr reftigolant
and lubricant vapor or mist.
lf accidental svstem 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
comoressed air.
@ some mixturos ot air and R'13'la have
b.6n shown to b€ combustible at glsvated pressur€s

Additional health and satetY information may be ob-
tained from the refrigerant and lubricant manufactures'
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).
