Under no circumstances should the accessory drive belt, tensioner or pulleys be lubricated as potential damage to the belt material and tensioner damping mechanism will occur. Do not apply any fluids or belt dressing to the accessory drive belt or pulleys.

Belt/pulley contamination
Incorrectly routed belt
Pulley misalignment or excessive pulley runout

Incorrectly routed power steering tubes (rubbing)

Eliminate all other non-belt related noises that could cause belt misdiagnosis, such as A/C compressor engagement chirp, power steering cavitations at low temperatures, variable camshaft timing (VCT) tick or generator whine.

If a concern is found, correct the condition before proceeding to the next section.

V- Ribbed Serpentine Belt With Piling

  1. Small scattered deposits of rubber material. This is not a concern, therefore, installation of a new belt is not required.
  3. Longer deposit areas building up to 50 percent of the rib height. This is not considered a concern but it can result in excessive noise. If noise is apparent, install a new belt.
  5. Heavy deposits building up al
