the tubes.
(b) Install the liquid tube and suction tube on the expansion
valve.
(c) Using a knife, cut off packing paper of packing while peel
off the paper, as shown in the illustration.
HINT:
Leave the packing paper untaped on the tube side so that the
installation bolt hole for remains visible.

NOTICE:
When installing the expansion valve, take care so that the
packing is not jammed with the evaporator.
(g) Peel off the remaining packing paper and apply the pack-
ing to expansion valve.
4. INSTALL HEATER RADIATOR
(a) Install the heater radiator to heater case.
(b) Install the heater radiator pipe with 2 clips.

ON±VEHICLE INSPECTION
1. INSPECT COMPRESSOR FOR METALLIC SOUND
(a) Start engine.
(b) Check if there is a metallic sound from the compressor
when the A/C switch is on.
If metallic sound is heard, replace the compressor assembly.
2. INSPECT REFRIGERANT PRESSURE
See ºON±VEHICLE INSPECTIONº of AIR CONDITIONING
SYSTEM on page AC±3.
3. INSPECT COMPRESSOR LOCK SENSOR RESIS-
TANCE
(a) Disconnect the connector.
(b) Measure resistance between terminals 1 and 2.
Standard resistance: 65 ± 125 W at 20 °C (68 °F)
If resistance is not as specified, replace the compressor assem-
bly.
4. INSPECT VISUALLY FOR LEAKAGE OF REFRIGER-
ANT FROM SAFETY SEAL
Using a gas leak detector, check for leakage of refrigerant.
If there is any leakage, replace the compressor assembly.
5. CHECK FOR LEAKAGE OF GREASE FROM CLUTCH
BEARING
6. CHECK FOR SIGNS OF OIL ON PRESSURE PLATE OR
ROTOR
7. INSPECT MAGNETIC CLUTCH BEARING FOR NOISE
(a) Start engine.
(b) Check for abnormal noise from near the compressor
when the A/C switch is OFF.
If abnormal noise is being emitted, replace the magnetic clutch.
8. INSPECT MAGNETIC CLUTCH OPERATION
(a) Disconnect the connector.
(b) Connect the positive (+) lead from the battery to terminal
4 and the negative (±) lead to the body ground.
(c) Check that the magnetic clutch is energized.
If operation is not as specified, replace the magnetic clutch.
