INSPECTION
1. DRAIN ENGINE COOLANT
2. REMOVE AIR CLEANER ASSEMBLY
3. REMOVE GLOW PLUGS
(a) Remove the glow plug cap.
(b) Remove the 3 bolts.
(c) Remove the glow plug plate.
(d) Remove the glow plug stay.
(e) Remove the 3 glow plugs.
4. INSPECT GLOW PLUGS
Using an ohmmeter, check that there is continuity between the
glow plug terminal and ground.
Standard resistance at 20C (68F):
Approx. 0.22 Ω
If there is continuity, replace the glow plug.

ON–VEHICLE INSPECTION
1. MAKE THESE VISUAL CHECKS:
(a) Leakage of grease from the clutch bearing
(b) Signs of oil on the pressure plate or rotor
2. INSPECT MAGNETIC CLUTCH BEARING FOR NOISE
(a) Start the engine.
(b) Check for abnormal noise from the compressor when the
A/C switch is OFF.
If abnormal noise is being emitted, replace the magnetic clutch.
3. INSPECT MAGNETIC CLUTCH OPERATION
(a) Disconnect the connector.
(b) Connect the positive (+) lead from the battery to the termi-
nal 3 on the magnetic clutch connector 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.
4. INSPECT COMPRESSOR LOCK SENSOR RESIS-
TANCE
(a) Disconnect the connector.
(b) Measure resistance between terminals 1 and 2.
Standard resistance: 65 – 125 Ω at 20C (68F)
