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.

Additional health and safety information may be ob-
tained from the retrigerant and lubricant manufactures.
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).

lgnition Timing Inspection and Setting
1.Start the engine. Hold the engine at 3,00O rpm with
no load (A/T in S or E position, M/T in neutral) until
the radiator fan comes on, then let it idle.
Pull out the service check connector located behind
the right kick panel. Connect the BRN/WHT and BLK
terminals with the SCS short connector.
4. Adiust ignition timing, if necessary, to the follow-
ing specifications:
lgnition Timing:
16 t 2 BTDC (RED) at 75O 1 50 rpm in noutral
NOTE:
a Shift lever must be in neutral.
a All electrical systems should be turned OFF.DATA LINKCONNECTOR {3-P}NOTE: Do not attachthe jumper wire.

tion shown (toward the No. 1 cylindetl,
2.Align the index mark on the distributor housing with
the index mark on the end of the shaft.

1 . Check the condition of the wire terminals. lf any te.-
minal is corroded, clean it. and if it is broken or dis-
torted. reolace the wire.

Alternator Belt Inspection and Adjustment
Deflection Method:
Apply a force of 100 N (1o kgt, 22 lbJ) and measure the
deflection between the alternator and the crankshatt
pulley.
Detlsction:9-11 mm (0.35-O.43 inl
NOTE; On a brand-new belt {one that has be€n run
for less than five minutes), the deJlection should be
6-8 mm 1O.23-O.32 in) wh€n first measured. lf
the belt is worn or damaged, replace it.

lf adiustment is nocessarY:
1. Loosen the alternator adjusting nut and mounting

2. Move the alternator to obtain the proper belt tension,
then retighten the adjusting nut and mounting nut
to the specified torques.
3. Recheck the deflection ot the belt.
NOTE: lt necessary, adiust the P/S pump belt (see
section 17) and A/C compressor belt lsee section
22t.

Boh Tsnsion Gaug6 Mothod:
Foltowing the gauge manuJacturer's instructions, attach
the belt tension gauge to the belt and measure the
tension.
Tension: 340-49O N (35-50 kgl, 77-110 lbfl
NOTE: On a brand-new belt (one that has been run
for less than tive minutes), tension should be
690-880 N (70-90 kgt, 154- 198 lbJ) when tirst
measured. lf the belt is worn or damaged, replace it.
lf adi$tmsnt is nscaasary:
1. Loosen the alternator adiusting nut and mounting
nut.
2. Move ths ahernator to obtain the proper bslt tension,
then retighten the adjusting nut and mounting nut
to the specified torques.
3. Recheck the tension of the belt,
