(1) Compressor
Operation of Magnetic Clutch
1. Turn off the A/C switch after starting the engine.
2. Check whether abrasion or abnormal noise is heard when only
the magnetic clutch pulley is running.
3. Check that the magnetic clutch (1) does not slip when the A/C
switch and blower switch are turned "ON" (when the air
conditioner is in operation).
4. If anything abnormal is found, repair or replace.

Stator Coil
1. Measure the resistance of the stator coil with an ohmmeter
across the 1P connector (1) of magnetic clutch and compressor
body.
2. If the measurement is not within the factory specifications,
replace the stator coil.

Adjusting Air Conditioner Belt Tension
• Be sure to stop the engine before checking air conditioner
belt tension.
1. Stop the engine and remove the key.
2. Apply 98 N (10 kgf, 22 lbf) pressure to the belt between the
pulleys.
3. If tension is incorrect, adjust the belt tension.
4. If belt is damaged, replace it.
