Removal and Installation

1. | Disconnect the battery negative terminal first, then the positive terminal.

Tightening torque :
(+) terminal : 7.8 ~ 9.8N.m (0.8 ~ 1.0kgf.m, 5.8 ~ 7.2lb-ft)
(-) terminal : 4.0 ~ 6.0N.m (0.4 ~ 0.6kgf.m, 3.0 ~ 4.4lb-ft)

2. | Remove the VIS (Variable intake system) actuator and valve (A).

3. | Disconnect the A/C compressor switch connector (A) the alternator connector (B), and the cable from alternator "B" terminal (C).

4. | Remove the drive belt (A) after turning the drive belt tensioner (B) counterclockwise.

5. | Pull out the through bolt and then remove the alternator (A).

Tightening torque :
49.0 ~ 63.7N.m (5.0 ~ 6.5kgf.m, 36.2 ~ 47.0lb-ft)

6. | Installation is the reverse order of removal.

Disassembly

1. | Remove the alternator cover (A) using a screw driver after loosening the nuts (B).

2. | Loosen the mounting bolts (A) and disconnect the brush holder assembly (B).

3. | Remove the pulley (A) using the SST (09373-27000) (B).

4. | Loosen the 4 through bolts (A).

5. | Disconnect the rotor (A) and cover (B).

6. | Reassembly is the reverse order of disassembly.

Inspection

Inspect Rotor

1. | Check that there is continuity between the slip rings (C).

2. | Check that there is no continuity between the slip rings and the rotor (B) or rotor shaft (A).

3. | If the rotor fails either continuity check, replace the alternator.

Inspect Stator

1. | Check that there is continuity between each pair of leads (A).

2. | Check that there is no continuity between each lead and the coil core.

3. | If the coil fails either continuity check, replace the alternator.
