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).

Alternator Replacement
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 powet to the radio and turn it on.
When the word "CODE" is displayed, enler the cus-
tomer's 5-digit code to restore radio operation.
1 . Disconnect the ground cable from the battery nega-
tive (- ) terminal.
2. Disconnect the alternator connector from the al-
rernaror.

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
nur.
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,
NOTE: lf necessary, adjust the P/S pump belt (see
section 17) and A/C compressor belt (see section
22t.
