Accessory Drive Belt Inspection

WARNING!

• Do not attempt to inspect an accessory drive belt with vehicle running.
• When working near the radiator cooling fan, disconnect the fan motor lead. The fan is temperature controlled and can start at any time regardless of ignition switch position. You could be injured by the moving fan blades.
• You can be badly injured working on or around a motor vehicle. Only do service work for which you have the knowledge and the proper equipment. If you have any doubt about your ability to perform a service job, take your vehicle to a competent mechanic.

When inspecting accessory drive belts, small cracks that run across ribbed surface of belt from rib to rib, are considered normal. These are not a reason to replace belt.

However, cracks running along a rib (not across) are not  normal. Any belt with cracks running along a rib must be replaced. Also have the belt replaced if it has excessive wear, frayed cords or severe glazing.

Conditions that would require replacement:

• Rib chunking (one or more ribs has separated from belt body)
