Pressure too high on both low
and high pressure sides
No air bubbles seen through the
sight glass even when the engine
rpm is lowered Unable to develop sufficient per-
formance due to excessive refrig-
eration system

(1) Clean condenser
(2) Check cooling fan with fluid
coupling operation
(3) If (1) and (2) are in normal
state, check amount of refrigerant,
and charge proper amount of re-
frigerant

PRECAUTION
1. DO NOT HANDLE REFRIGERANT IN AN ENCLOSED
AREA OR NEAR AN OPEN FLAME
2. ALWAYS WEAR SAFETY GLASSES FOR EYE
PROTECTION
3. AVOID YOUR EYES AND SKIN TO CONTACT WITH
LIQUID REFRIGERANT
If you get the liquid refrigerant in your eyes or on your skin:
(a) Wash out the area with lots of cold water.
CAUTION:
Do not rub your eyes or skin.
(b) Apply clean petroleum jelly to the skin.
(c) Go immediately to a physician or hospital for professional
treatment.
4. NEVER HEAT CONTAINER OR EXPOSE IT TO NAKED
FLAME
5. DO NOT DROP CONTAINER NOR APPLY PHYSICAL
SHOCKS TO IT.
6. DO NOT OPERATE COMPRESSOR WITHOUT
ENOUGH REFRIGERANT IN REFRIGERANT SYSTEM
If there is not enough refrigerant in the refrigerant system, oil lu-
brication will be insufficient and compressor burnout may occur.
To avoid this, always keep enough refrigerant in the refrigerant
system.
7. DO NOT OPEN HIGH PRESSURE MANIFOLD VALVE
WHILE COMPRESSOR IS OPERATING
If the high pressure valves opened, refrigerant flows in the re-
verse direction and could cause the charging cylinder to rup-
ture, so open and close the only low pressure valve.
8. DO NOT OVERCHARGE REFRIGERANT SYSTEM
WITH REFRIGERANT
If refrigerant is overcharged, it causes problems such as insuffi-
cient cooling, poor fuel economy, engine overheating etc.

COMPRESSOR AND MAGNETIC
CLUTCH
ON-VEHICLE INSPECTION
1. INSPECT COMPRESSOR FOR METALLIC SOUND
Check there is abnormal metallic sound from the compressor
when the A/C switch is ON.
If abnormal metallic sound is heard, replace the compressor as-
sembly.
2. INSPECT REFRIGERANT PRESSURE
(See page AC-3)
3. INSPECT VISUALLY FOR LEAKAGE OF REFRIGER-
ANT
Using a gas leak detector, check for leakage of refrigerant.
If there is any leakage, replace the compressor assembly.
4. INSPECT COMPRESSOR LOCK SENSOR RESIS-
TANCE
(a) Disconnect the connector.
(b) Measure resistance between terminal 1 and 2.
Standard resistance:
570 - 1,050 W at 20°C (68 °F)
If resistance is not as specified, replace the compressor.
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 the compressor when the
A/C switch is OFF.
If abnormal noise is being emitted, replace the rotor of magnetic
clutch.
8. INSPECT MAGNETIC CLUTCH OPERATION
(a) Disconnect the connector.
(b) Connect the positive (+) lead from the battery to terminal
3 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.
