6. Next, you need to remove the serpentine belt. Loosen the two alternator bolts. A 12 mm and a 14 mm bolt need to be removed. Loosen the bolt that tightens the serpentine belt. Now, you can push the alternator down and remove the serpentine belt.
7. Remove the alternator. The electrical connector should be disconnected at this point.
