Repair procedures
Replacement
1. Discharge refrigerant from refrigeration system.
2. Replace faulty tube or hose.
CAUTION
Cap the open fittings immediately to keep moisture or dirt out of the system.
3. Tighten joint of bolt or nut to specified torque.
CAUTION
Connections should not be torque tighter than the specified torque.
4. Evacuate air in refrigeration system and charge system with refrigerant.
Specified amount: 510 +- 25g (17.9 +- 0.88oz)
5. Inspect for leakage of refrigerant.
Using a gas leak detector, check for leakage of refrigerant.
6. Inspect А/С operation.

Repair procedures
Removal
1. If the compressor is marginally operable, run the engine at idle speed, and let the air conditioning work for a few minutes, then shut the engine off.
2. Disconnect the negative cable from the battery.
3. Recover the refrigerant with a recovery/charging station.
4. Loosen the drive belt.
(Refer to EM group - "Drive belt")
5. Loosen the mount bolts and then remove the under cover (A).
6. Remove the bolts, then disconnect the suction line (A) and discharge line (B) from the compressor. Plug or cap the lines immediately after disconnecting them to avoid moisture and dust contamination.
7. Disconnect the compressor clutch connector, and then remove mounting bolts and the compressor (B).
Installation
1. Make sure of the length of compressor mounting bolts, and then tighten it A†’B†’C†’D order.
Tightening torque: 20.0~32.9N.m (2.04~3.36kgf.m, 14.7~24.3lbf.ft)
2. Install in the reverse order of removal, and note these items.
Be sure to use the right О-rings for R-134a to avoid leakage.
Inspection
1. Check the plated parts of the disc & hub assembly (A) for color changes, peeling or other damage. If there is damage, replace the clutch set.
2. Check the pulley (B) bearing play and drag by rotating the pulley by hand. Replace the clutch set with a new one if it is noisy or has excessive play/drag.
3. Check operation of the magnetic clutch. Connect the compressor side terminals to the battery (+) terminal and the ground battery (-) terminal to the compressor body. Check the magnetic clutch operating noise to determine the condition.
Disassembly
1. Remove the front left tire (A).
2. Loosen the mount bolts and then remove the under cover (A).
3. Remove the engine side cover (A).
4. Remove the wheel house (A).
5. Remove the center bolt (A) while holding the disc & hub assembly with SST( 09977-29000).
Tightening torque: 10~15N.m (1.02~1.53kgf.m, 7.37~11lbf.ft)
6. Remove the disc & hub assembly (A).
7. Loosen the drive belt.
(Refer to EM group - "Drive belt")
8. Disconnect the retainer ring (A) and then remove the pulley (B).
NOTE
9. Remove the retainer ring (B) and then remove the field coil (C). Be careful not to damage the coil and compressor.
10. To prepare work space, loosen the compressor mounting bolts.
11. Disconnect the connector and ground screw and than remove the field coil (A).
12. Reassemble the compressor clutch in the reverse order of disassembly, and note these items:
