Drive Belt: Symptom Related Diagnostic Procedures
Description
The following are symptomatic noises of the accessory drive belt system:
1. Chirping:
^
A high pitched noise that is usually heard once per revolution of a pulley or a belt.
^
It is most common on cold, damp mornings.
^
Verify this condition by squirting water onto the belt. The noise will momentarily stop.
2. Squeal:
^
A loud screeching noise That is caused by a slipping belt (this is unusual for a multiple ribbed belt).
^
The noise occurs when a heavy load is applied to the belt, such as an air conditioning compressor engagement, snapping the throttle, or
slipping on a seized pulley.
3. Whine: A high pitched continuous noise that may be caused by a failed component bearing.
4. Faint Cycle Rumbling: A low frequency noise heard once per revolution of the belt.
5. Pilling:
^
The random accumulation of rubber dust in the bottom of the multi-ribbed belt grooves.
^
A small amount of pilling is normal.
^
Operation of the drive belt system will not be effected unless the buildup exceeds one third (1/3) of the belt groove depth.
NOTE: Multiple ribbed, accessory drive belts wear evenly with their pulleys. Unusual wear indicates a correction is needed. The following diagnostic
tables will aid in diagnosing drive belt system problems.
