Replacement (cont'd)
9. Remove the bolts, the suction service valve and theO-ring from the compressor,
lf necessary, remove the compressor bracket as fol-lows.
. Remove the nut and the washer from the left frontmount. When tightening the nut to the left frontmount, make sure the washer is set p.operly onthe left front mount as shown.

1 1. Install in the reverse order of removal, and note thesertems:
lf you're installing a new compressor. drain all therefrigerant oil from the removed compressor. andmeasure its volume. Subtract the volume ofdrained oil from '140 ml (4 28 fl{,z, 4.9 lmpoz); theresult is the amount of oil you should drain fromthe new compressor (through the suction fifting).Replace the O-rings with new ones at each fining,and apply a thin coat of refrigerant oil beforeinstalling them. Be sure to use the right O,ringsfor HFC-134a (R-134a) to avoid leakage.
Use refrigerant oil {DENSO, ND-OtL8) for HFC-134aDENSO piston type compressors only.To avoid contamination, do not return the oil tothe container once dispensed, and never mix itwith other refrigerant oils.
lmmediately after using the oil, replace the capon the container, and seal it to avoid moisture
absorption.
Do not spill the refrigerant oil on the vehicle; itmay damage the paint; if the refrigerant oil con-tacts the paint, wash it off immediatelv.
Adjust the ly'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 itsperformance (see page 22-24!..

Compressor (DENSOI
Clutch Inspection
Check the plated parts of the pressure plate for colo.changes, peeling or other damage. lf there is dam-age, replace the clutch set.
Check the pulley bearing play and drag by rotatingthe pulley by hand, Replace the clutch set with a newone if it is noisy or has excessive play/drag.
Measure the clearance between the pullev and thepressure plate all the way around. lf the clearance isnot within specified limits, the pressure plate must beremoved and shim(s) added or removed as required,
following the procedure on page 22-41.
Clearanca:0.5 t 0.15 mm {0.020 r 0.006 in}
NOTE: The shims are availabte in three thicknesses:0.1 mm,0.3 mm and 0.5 mm.

. Check resistance of the field coil. lf resistance is notwithin specifications, replace the field coil.
Fiald Coil Resistanc€: 3.it to 3.8 O at 20.C l68.Fl

Compressor (DENSO)
Clutch Overhaul (cont'd)
Remove the screw from the field coil ground termi-nal. Remove the snap ring A with snap ring pliers.
then remove the field coil. Be careful not to damaoethe field coil and compressor.
SNAP NING AReplace.
Reassemble the compressor clutch in the reverseorder of disassembly, and note these rrems:
o Install the field coil with the wire side facingdown.
a Clean the pulley and compressor sliding surfaceswith non-petroleum solvent.. Install new snap rings, and make sure thev arefully seated in the groove.
. Make sure that the pulley turns smoothly afterit's reassembled.
. Route and clamp the wires p.operly or they canbe damaged by pulley.

Recover the refrigerant with a recovery/recycling/charging station {see page 22-27),
Remove the relief valve and the O-ring. plug theopening to keep foreign matter from entering thesystem and the compressor oilfrom running out.
Clean the mating surfaces.
Replace the O-ring with a new one at the relief valve.and apply a thin coat of refrigerant oil before install-ing it.
Remove the plug, and install and tighten the reliefvatve.
Charge the system (see page 22-46), and test its per-formance (see page 22-24),

Condenser
Replacement
1.Recover the refrigerant with a recovery/recycling/
charging station lsee page 22-271.
Disconnect the condenser fan connector from theAy'C wire harness, then remove the A,/C wire harnessfrom the condenser fan shroud.
Remove the bolts, then disconnect the dischargeand condenser lines from the condenser.
NOTE: Plug or cap the lines immediately after dis-connecting them to avoid moisture and dust con-tamination,

5. Install in the reverse order of removal. Make note ofthe following items.
. lf you're installing a new condenser, add refriger-ant oil (SANDEN, SP-10 or DENSO, ND-O|L 8)
\see page 22-22l.-
. Replace the O-rings with new ones at each fit-ting, and apply a thin coat of refrigerant oilbefo.e installing them.
NOTE; Be sure to use the right O-rings for HFC,134a (R-134a) to avoid leakage.o Be careful not to damage the condenser finswhen installing the condenser assembly.. Charge the system (see page 22-46), and test itsperformance (see page 22-24i.

A/C System Service
Charging
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 irritale eyes, nose and
throat. Avoid breathing the air conditioner retrigerant
and lubricant vaoor or mist,
lf accidental system discharge occurs, ventilate workarea before resuming service, Additional health and
safety information may be obtained from the refrigerant
and lubricant manufacturers.
Refrigerant capacityt 600 - 650 g 121.1 - 22.9 ozl
CAUnON: Do not overcharg€ the system; the comprcssor
will be damaged.
Connect a R-134a refrigerant recovery/recycling/charging
station to the vehicle, as shown, following the equipment
manufacturer's instructions.

Leak Test
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 io air conditioner refrigerant and
lubricant vapot or mist can itritats eyes, no36 and thtoat.
Avoid breathing the air conditioner refrigeranl and lubri-
cant vapor or mist,
lf accidental system discharge occurs, ventilate workarea betore resuming service.
R-134a service equipment or vehicle air conditioner sys-
tems should not be pressure tested or leak tested with
comoressed air.
@ some mixtures of air and R-134a have
been shown to be combugtibls at elevatgd prossures
and can result in tire or explosion causing iniuly orplopgrty damage. Nev€r usc compre33od air to pressure
test R-13'la servica oquipment or yohiclo air conditionor
systems.
Additional health and safety information may be obtained
from the refrigerant and lubricant manufacturers.
1. Connect a R-134a refrigerant recove rylrecycling/
charging station to the vehicle, as shown in the pre-
vious column, following the equipment manufactur-
er's instructions.
NOTE; Be sure to install the same amount of new
refrigerant oil back into the A,/C system before charg-In9.
Open the high-pressure valve to charge the system
to the specified capacity, then close the supply
valve, and remove the charging system couplers.
Rofrigerant capacity: 600 - 650 g (21.1 - 22.9 oz)
Check the system for leaks using a R-134a refriger-
ant leak detector with an accuracy of 14 9 10.5 ozlper yea. or better.
lf you find leaks that require the system to be opened(to repair or replace hoses. fittings. etc.), recover the
system according to the Recovery Procedure on page
22-27.
After checking and repairing leaks. the system must
be evacuated (see System Evacuation on page 22-451.
