Overhaul
L Pull out the Ay'C thermostat sensor from the evapo-rator fins.
2. Remove the self-tapping screws and clamps fromthe housing.
3. Carefully separate the housings and remove theevaporator.
4. lf necessary, remove the expansion valve.
NOTE: When loosening the expansion valve nuts.use a second wrench to hold the expansion valve orevaporator pipe. Otherwise, they can be damaged.
Assemble in the reverse order of disassembly, and:
. feplace the O-rings with new ones at each fitting,and apply a thin coat of refrigerant oil (ND-OIL 8:P/N 38899 - PR7 - A01) before installing them.NOTE: Be sure to use the right O-rings for HFC-134a {R-134a) to avoid leakage.. install the expansion valve capillary tube withthe capillary tube in contact with the suction linedi.ectly, and wrap it with tape.. reinstall the Ay'C thermostat sensor to its originallocation.

Glutch Inspection
Check the plated parts ot the pressure plate tor color
changes. peeling or other damage. lf there is dam-
8ge, replace the clutch set.
Check the pulley bearing play and drag by rotating
the pulley by hand. Replace the clutch set with a new
one if it is noisv or has excessive play/drag
Measure the clearance betlveen the pulley and the
pressure plate all the way around. lf the clearance is
not within specified limits, the pressure plate must be
removed and shims added or removed as required.
Jollowing the procedure on page 22-33.
Clearrnce: 0.50 t 0.15 mm {0.02 i 0.01 inl
NOTE: The shims are available in three thicknesses:
0.1 mm, 0.3 mm and 0.5 mm.

A/C System Service
Leak Test
Only use 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: Exposura to air condition ratrigerant and
lubaicant vapor or mist can irritato oyes. nose and
throat. Avoid br€athing tho sir conditionsr reftigolant
and lubricant vapor or mist.
lf accidental svstem 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
comoressed air.
@ some mixturos ot air and R'13'la have
b.6n shown to b€ combustible at glsvated pressur€s
and can result in firo or sxplo3ion causing iniury or

Additional health and satetY information may be ob-
tained from the refrigerant and lubricant manufactures'
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).
