Alternator Pulley Inspection
Perform the following.
- Make sure that alternator pulley does not rattle.
- Make sure that alternator pulley nut is tight.

Alternator pulley nut: 118 Nm (12.0 kg-m, 87 ft-lb)

Installation
Installation is the reverse order of removal.

CAUTION:
Be sure to tighten "B" terminal nut carefully.
- Install alternator, and check tension of belt. Procedures.
- For this model, the power generation voltage variable control system that controls the power generation voltage of the alternator has been adopted. Therefore, the power generation voltage variable control system operation inspection should be performed after replacing the alternator, and then make sure that the system operates normally.
