Drive Belt: Description and Operation

Drive Belt Tensioner:

A single serpentine belt is used to drive all engine accessories formerly driven by multiple drive belts. All belt driven accessories are rigidly mounted with belt tension maintained by a spring loaded tensioner.

Inspect
^ Routine inspection of the belt may reveal cracks in the belt ribs. These cracks will not impair belt performance and therefore should not be considered a problem requiring belt replacement.
^ The belt should be replaced if sections of the belt ribs are missing or if the belt is outside of the tensioner's operating range. See illustration.

Important
^ Belt tension is maintained by the tensioner and is not adjustable.
