ALTERNATOR / FAN BELT
Adjust alternator/fan belt tension when belt
slackness exceeds the spec below, and when
belts are replaced.
To adjust alternator/fan belt tension:
1. Loosen bolt (B).
2. Turn adjusting bolt (A) to move alternator away
from the engine until a force of 22 lbs. (100 N)
deflects belt 5/16 to 1/2 inch (8 to 12 mm) at
mid-span between fan pulley and alternator
pulley. Over-tightening will result in alternator
damage.
3. Tighten bolt (B).
4. Recheck tension after tightening bolts to ensure
no movement occurred during tightening.
Readjust as necessary.
NOTE: When installing new belts,
• Always replace belts as a set.
• Use genuine OEM belts.
• Never pry belt over pulley. Loosen necessary
hardware and adjust belt tension.
• Re-adjust tension of a new belt after a short
run-in period. (About 5 hours.)
