Drive Belt: Diagrams

SERPENTINE DRIVE BELT REPLACEMENT
Maintain the serpentine drive belt and pulleys can extend the normal life of a drive belt.
PULLEY INSPECTION
Examine the pulleys for chips, nicks, tool marks, cracks, bent sidewalls, corrosion or other damage.
1. Place a straightedge or position a cord across the two pulleys so they touch at all points.
2. Turn each pulley one half revolution and recheck with a straightedge or cord. Full contact at all points must be made. If contact is not made at all points, the pulley may be warped or its shaft could be bent. Replace any parts found to be damaged.
DRIVE BELT INSPECTION
Replace a frayed or cracked belt. Do not use drive belt dressings to extend belt life.
