Recovery
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 system.
CAUTION: Exposure to air conditioner refrigerant and
lubricant vapor or mist can irritate eyes, nose and
throat. Avoid brqathing the air conditioner retrigerant
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 arr.
@@ some mixtures of air and R-134a have been
shown to be combustible at elevated plessures and can
result in fire or explosion causing iniury or property dam-
age. Never use compressed air to pressure tect R-134a
service equipment or vehicle air conditioner systems.
Additional health and safety intormation may be obtained
from the refrigerant and lubricant manufacturers.
'1. Connect a R-134a refrigerant recove rylrecycling/
charging station to the vehicle, as shown, following
the equipment manufacturer's instructions
2. Measure the amount of refrigerant oil removed trom
the A,/C system after the recovery process is com-
oleted. Be sure to install the same amount of new
refrigerant oil back into the AVC system before charg-
inq.

ly on the left front mount as shown.

10. Check the idler pulley bearing for play and drag,
and replace it with a new one if it's noisy or has
excessive play or drag.
lnstall in the reverse order of removal. Make note of
the following items,
. lf you're installing a new compressor, drain all the
reJrigerant oil from the removed compressor, and
measure its volume. Subtract the volume of
drained oil trom 130 m/ 14 U3 fl'o2,4.6 lmp'oz);
the result is the amount of oil you should drain
lrom the new compressor (through the suction fit-
trngl.
. Replace the O-rings with new ones at each fit-
ting, and apply a thin coat o{ refrigerant oil
before installing them. Be sure to use the right
O-rings for HFC-134a (R-134a) to avoid leakage.
. Use refrigerant oil (SP-10) for R-134a KEIHIN spi-
ral type compressors only.
. To avoid contamination, do not return the oil to
the container once dispensed, and never mix it
with other refrigerant oils.
. lmmediately after using the oil, replace the cap
on the container. and seal it to avoid moisture
aDsorprlon.
. Do not spill the refrigerant oil on the vehicle; it
may damage the paint; if the retrigerant oil con-
tacts the Daint, wash it off immediately.
. Adjust the Ay'C compr'essor b€lt (see psge 22-69)
and the power steering pump belt {see section
17t.
. Charge the system (see page 22-611, and test its
performance (see page 22-56]-.

Troubleshooting
Tips and Precautions
Bef ore Troubleshootin g
. Check applicable fuses in the appropriate fuse/relay
box.
. Check the battery for damage, state of charge, and
clean. and tight connections.
. Check the alternator belt tension.
CAUTION:
. Do not quick-charge a battery unless the battery
ground cable has been disconnected, otherwise you
will damage the alternator diodes.
. Do not attempt to crank thc engins wilh the battery
ground cable loosely connected or you will severely
damage the wiring.
Handling Connestors
. Make sure the connectors are clean and have no loose
wire terminals,
. N4ake sure multiple cavity connectors are packed with
grease (except water-tight connectors).
. All connectors have push-down release type locks.
Some connectors have a clip on their side used to
attach them to a mount bracket on the body or on
another component. This clip has a pull type lock.
Some mounted connectors cannot be disconnected
unless you first release the lock and remove the con-
nector from its mount bracket.
LOCKINGPAWL ONOTHERHALF OFPulltodisengage
LOCKING TAB
CONNECTORBRACKET
Never try to disconnect connectors by pulling on
their wires; pull on the connector halves instead.
Alwavs reinstall olastic covers.
Before connecting connectors, make sure the termi-
nals are in place and not bent.
. Check for loose retainers and rubber seals.
RETAINER
The backs of some connectors are oacked with
grease. Add grease if necessary. lf the grease is con
taminated. reolace it.
