Inspect and Adjust Alternator/Fan Belt

Replace if worn or damaged. (See procedure in Service section.)

NOTE: Run engine for five minutes to warm a cold belt. Let a hot belt cool for 15 minutes before adjustment.

Check tension by pressing belt midway between pulleys. Belt should deflect about 19 mm (3/4 in.) at 89 N (20 lb force).

IMPORTANT: Pry against alternator frame only.

Adjust tension by loosening cap screw (A) and mounting bolt (B). Apply force to alternator frame (C) until belt tension is correct. Tighten cap screw and bolt.
