Removal (AWD Models)
1. Disconnect the battery cable from the negative terminal.
2. Remove power steering oil reservoir tank from the bracket.
3. Remove the clips (A) and the hose clamp (B) from the harness
bracket (1).
4. Remove engine front undercover, using power tools.
5. Remove alternator and power steering oil pump belt. Refer to
EM-16, "
DRIVE BELTS" .
6. Remove alternator mounting bolt (A) and alternator stay mount-
ing bolt (B) using power tools, then remove alternator stay (1).
7. Remove alternator mounting bolt (C), using power tools.
8. Pull and turn alternator, and then remove the harness bracket
bolts (A).
9. Disconnect alternator connector (1).
10. Remove “B” terminal nut (2).

Alternator Pulley Inspection
Perform the following.

Make sure that alternator pulley does not rattle.

Make sure that alternator pulley nut is tight.
Installation
Installation is the reverse order of removal.
CAUTION:
Be sure to tighten “B” terminal nut carefully.

Install alternator, and check tension of belt. Refer to EM-16, "Checking Drive Belts" .

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 sys-
tem operation inspection should be performed after replacing the alternator, and then make sure that the
system operates normally. Refer to SC-29, "
Power Generation Voltage Variable Control System Operation
Inspection" .
