DIAGNOSIS

1. If legible, inspect the part number on the alternator compressor drive belt.
   • If the manufacturer is Bando or the part number is 38920-P8F-A04, go to REPAIR PROCEDURE.
   • If the manufacturer (Bando) or the part number is not legible, go to step 2.
2. Warm up the engine to operating temperature (cooling fans cycle twice), and turn on the A/C at its lowest setting. Let the engine idle.
   1. If you hear a buzzing noise from the area of the alternator when the A/C compressor runs, go to REPAIR PROCEDURE.

• If the buzzing noise is coming from another area, continue troubleshooting.

 

REPAIR PROCEDURE

1. Move the auto-tensioner to relieve tension on the alternator-compressor belt, and remove the belt.

 

2. Loosen the two alternator mounting bolts. Torque the 10 mm bolt to 39 to 43 N^.m (29 to 32 lb-ft) and the 8 mm bolt to 20 to 22 N^.m (15 to 16 lb-ft).

NOTE: Use these torque values only to address this problem. For all other work, use the torque specifications in the service manual.

 

3. Install the new belt.
4. Warm up the engine to operating temperature (cooling fans cycle twice), and turn on the A/C at its lowest setting. Let the engine idle, and when the A/C compressor runs, make sure that the noise is gone.
