1. Remove the evaporator core (see page 21-78).
2. Remove the bolts (A) and expansion valve (B).
3. Install the expansion valve in the reverse order of
removal and note these items:
 If you’re installing a new expansion valve, add refrigerant oil (SP-10) (see page 21-7).
 Replace the O-rings with new ones at each fitting, and apply a thin coat of refrigerant oil before
installing them. Be sure to use the correct O-rings
for HFC-134a (R-134a) to avoid leakage.
 Immediately after using the oil, reinstall 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 paint; if the refrigerant oil
contacts the paint, wash it off immediately.
 Make sure that there is no air leakage.
 Charge the system (see page 21-92).

7. Remove the mounting bolts and the A/C
compressor (A). Be careful not to damage the
radiator fins when removing the A/C compressor. 8. Install the compressor in the reverse order of
removal, and note these items:
 Inspect the A/C lines for any signs of contamination.
 If you’re installing a new A/C compressor, you must calculate the amount of refrigerant oil to be
removed from it (see page 21-7). A new A/C
compressor comes with a full charge of oil.
 Replace the O-rings with new ones at each fitting, and apply a thin coat of refrigerant oil before
installing them. Be sure to use the correct O-rings
for HFC-134a (R-134a) to avoid leakage.
 Use refrigerant oil (SP-10) for HFC-134a SANDEN spiral type A/C compressor only.
 To avoid contamination, do not return the oil to the container once dispensed, and never mix it
with other refrigerant oils.
 Immediately after using the oil, reinstall 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 paint; if the refrigerant oil
contacts the paint, wash it off immediately.
 Charge the system (see page 21-92).

A
1. Check the armature plate for discoloration, peeling,or other damage. If there is damage, replace the
clutch set (see page 21-86).
2. Check the rotor pulley bearing play and drag by rotating the rotor pulley by hand. Replace the
clutch set with a new one if it is noisy or has
excessive play/drag (see page 21-86).
3. Measure the clearance between the rotor pulley (A) and the armature plate (B) all the way around. If the
clearance is not within specified limits, remove the
armature plate (see page 21-86) and add or remove
shims as needed to increase or decrease clearance.
NOTE: The shims are available in four thicknesses:
0.1 mm, 0.2 mm, 0.4 mm, and 0.5 mm. 4. Check the thermal protector for continuity between
the A/C compressor clutch connector terminals
No. 1 and No. 3. If there is no continuity, replace the
thermal protector (see page 21-87).
NOTE: The thermal protector will have no
continuity above about 122 to 128 °C (252 to 262 °F).
When the temperature drops below about 116 to
104 °C (241 to 219 °F), the thermal protector will
have continuity.
5. Disconnect the field coil connector (A). Check resistance of the field coil. If resistance is not within
specifications, replace the field coil (see page
21-86).

1. Remove the center nut while holding the armature plate (A) with a commercially available A/C clutch
holder (B).
2. Remove the armature plate (A) and shim(s) (B), taking care not to lose the shim(s). If the clutch
needs adjustment, increase or decrease the
number and thickness of shims as necessary, then
reinstall the armature plate, and recheck its
clearance (see page 21-85).
NOTE: The shims are available in four thicknesses:
0.1 mm, 0.2 mm, 0.4 mm, and 0.5 mm. 3. If you are replacing the field coil, remove the snap
ring (A) with snap ring pliers, then remove the rotor
pulley (B). Be careful not to damage the rotor pulley
and A/C compressor.
4. Remove the bolt and holder (A), then disconnect the field coil connector (B). Remove the snap ring
(C)withsnapringpliers,thenremovethefieldcoil
(D). Be careful not to damage the field coil and A/C
compressor.
5. Reassemble the clutch in the reverse order of disassembly, and note these items:
 Install the field coil with the wire side facing down, and align the boss on the field coil with the
hole in the A/C compressor.
 Clean the rotor pulley and A/C compressor sliding surfaces with contact cleaner or other
non-petroleum solvent.
 Install new snap rings, note the installation direction, and make sure they are fully seated in
the groove.
 Make sure that the rotor pulley turns smoothly after it’s reassembled.
 Route and clamp the wires properly or they can be damaged by the rotor pulley.

refrigerant to the atmosphere, determine and correct
the cause of the excessive system pressure, then
replace the relief valve.
1. Recover the refrigerant with a recovery/recycling/ charging station (see page 21-90).
2. Remove the relief valve (A), and the O-ring (B). Plug the opening to keep foreign matter from entering
the system and the A/C compressor oil from
running out.
3. Clean the mating surfaces.
4. Replace the O-ring with a new one at the relief valve, and apply a thin coat of refrigerant oil before
installing it.
5. Remove the plug, and install and tighten the relief valve.
6. Charge the system (see page 21-92).

Refrigerant Recovery
A
C B
 Air conditioning refrigerant or lubricant vaporcan irritate your eyes, nose, or throat.
 Be careful when connecting service equipment.
 Do not breathe refrigerant or vapor.
NOTE:  If accidental system discharge occurs, ventilate the work area before resuming service.
 Additional health and safety information may be obtained from the refrigerant and lubricant
manufacturers.
1. Connect an R-134a refrigerant recovery/recycling/ charging station (A) to the high-pressure service
port (B) and the low-pressure service port (C), as
shown, following the equipment manufacturer’s
instructions. 2. Measure the amount of refrigerant oil removed
from the A/C system after the recovery process is
completed. Be sure to put the same amount of new
refrigerant oil back into the A/C system before
charging.
