3. If any of the accessories are damaged, or have a worn or damaged bearing or internal torsional resistance above normal. All accessories should be
rotatable by hand in the unloaded condition. If not, inspect the accessory.
4. If fluid gets on the drive belt. This includes power steering fluid, engine coolant, engine oil or air conditioning system lubricant. If fluid does get
on the drive belt during service, clean the drive belt with soap and water and thoroughly rinse with clean water. The drive belt does not have to be
replaced if no apparent damage has occurred.
5. If the drive belt is too long. A drive belt that is too long will allow the drive belt tensioner arm to go all the way to the arm travel stop under certain
load conditions, which will release tension to the drive belt. If the drive belt tensioner is resting on the stop, replace the drive belt.
NOTE: The drive belt tensioner arm should rotate freely without binding.
6. If the drive belt tensioner is worn or damaged.
