1.lf the compressor is marginally operable, run the
engine at idle speed, and let the air conditioner
work for a few minutes. then shut the engine off.
Disconnect the negative cable from the battery.
Recover the refrigerant with a recovery/recycling/
charging station (see page 22-27l..
Remove the bolts, then disconnect the suction and
discharge lines from the compressor.
NOTE: Plug or cap the lines immediately after dis-
connecting them to avoid moisture and dust con-
tamination.

10. lnstall in the reverse order of removal. Make note of
the following items.
. lf you're installing a new compressor, drain all
the refrigerant oil from the removed compressor,
and measure its volume. Subtract the volume of
drained oil from '130m? 14 1/3 tl'o2,4 6 lmp'oz);
the result is the amount of oil you should drain
from the new compressor (through the suction
fifting).
. Replace the O-rings with new ones at each fit-
ting, and apply a thin coat of refrigerant oil
before installing them
NOTE: Be sure to use the right O-rings for HFC-
134a (R-134a) to avoid leakage
. Use refrigerant oil (SP-10) for R-134a Sanden and
Hadsys spiral type compressors only'
o 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
absorption.
. Do not spill the refrigerant oil on the vehicle; it
may damage the painu if the refrigerant oil con-
tacts the paint, wash it off immediately
. Adjust the Ay'C compressor belt (see page 22-43)
and the power steering pump belt (see section 17)'
. Charge the system (see page 22-46), and test its
oerformance (see Page 22-241

Tips and Precautions
Bef ore Troubleshooting
. 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 disconneqted, otherwise you
will damage the alternator diodes.
. Do not attempt to crank the engine with the battery
ground cable loosely connecled or you will severely
damage the wiling,
Handling Connectois
. Make sure the connectors are clean and have no loose
wire terminals.
. Make sure multiple cavity connectors are packed with
grease (except watertight 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 pulltype lock.
Some mounted connectors cannot be disconnected
unless you first release the lock and remove the con-
nector from its mount bracket.

-Starter Test
NOTE; The air temoerature must be between 59 and
100'F (15 and 38"C) before testing.
Recommended Procedure:
. Use a staner system tester.
. Connect and operate the equipment in accordance
with the manufacturer's instructions.
. Test and troubleshoot as described,
Alternate Procedurg:
. Use the following equipment:- Ammeter, 0 - 400 A
- Voltmeter, 0 - 20 V (accurate within 0.1 volt)
- Tachometer, 0 - 1,200 rpm
. Hook up a voltmeter and ammeter as shown.
NEGATIVETERMINAL
NOTE: After this test, or any subsequent repair. reset
the ECM/PCM to clear any codes (see section l1)
Check the Start€r Engagemont:
1. Remove the No. 44 (15 A) fuse from the under-hood
fuse/relay box,
2. Turn the ignition switch to START (llll with the shift
lever in E or E position (rVT) or with the clutch pedal
depressed {M/T). The starter should crank the engine.
. lf the starter does not crank the engine, go to
step 3.
. lf itcranksthe engineerraticallyortooslowly, go
to "Check for Wear and Damage" on the next
page.
Check the battery. battery positive cable, ground,
starter cut relay, and the wire connections for loose-
ness and corrosion, Test again.
lf the starter still does not crank the engine, go to
step 4,
Unplug the connector (BLK,/WHT wire and solenoid
terminal) from the starter,
Connect a jumper wire from the battery positive (+)
terminal to the solenoid terminal.
The starter should crank the engine.
. lf the starter still does not crank the engine,
remove it, and diagnose its internal problem
. lf the startercranksthe engine, goto step 6.
Check the ignition switch (see page 23-891.
Check the starter cut relay and clutch interlock switch
(see page 23-86,87).
Check the A/f gear position switch (see page 23-154).
Check for an open in the wire between the ignition
switch and starter.

Starting System
Starter Test lcont'dl
Ch€ck tor Wear and Damage
The starter should crank the engine smoothly and
steadily, lf the starter engages. but cranks the engine
erratically, remove it, and inspect the starter drive gear
and torque converter or flywheel ring gear for damage.
. Check the drive gear overrunning clutch for binding
or slipping when the armature is rotated with the
drive gear held,- lf damaged. replace the gears.
Check Cranking Voltsge and Curr€nt Draw
Cranking voltage should be no less than 8.5 volts.
Current draw should be no more than 350 amperes.
lf cranking voltage is too low, or current draw too high,
check for;
. dead or low batterv.
. open circuit in starter armature commutator seg-
ments,
. starter armature dragging.
. shorted armature winding.
o excessive drag in engine.
Check Cranking rpm
Engine speed during cranking should be above 100 rpm,
lf speed is too low, check for:
. loose battery or stanerterminals.
. excessively worn starter brushes,
. open circuit in commutator segments.
o dirty or damaged helical spline or drive gear.
. defective drive gear overrunning clutch.
Check Siarter Disengag€ment
With the shift lever in El or @ position (A/T) or with the
clutch pedal depressed (M/T), turn the ignition switch to
START (lll), and release to ON (ll).
The starter drive gear should disengage from the torque
converter or flywheel ring gear when you release the
Key.
lf the drive gear hangs up on the torque converter or fly-
wheel ring gear, check for:
. solenoid plunger and switch malfunction,
. dirty drive gear assembly or damaged overrunning
clutch.
Starter Solenoid Test
1. Check the hold-in coil for continuitv between the S
terminal and the armature housing (ground). The
coil is OK if there is continuitv,

lnstallation:
NOTE: Before you install the distributor. bring the No. 1
piston to compression stroke TDC.
1. Coat a new O-ring with engine oil, then install it.
2. Slip the distributor into position
NOTE: The lug on the end of the distributor and its
mating grooves in the camshaft end are both offset
to eliminate the possibility of installing the distribu-
tor 180" out of time.
3. Installthe mounting bolts, and tighten them lightly.
