Drive Belt Tensioner Diagnosis

INSPECTION PROCEDURE

IMPORTANT: When the engine is operating the belt tensioner arm will move. Do not replace the belt tensioner because of movement in the belt tensioner arm.

NOTICE: Allowing the drive belt tensioner to snap into the free position may result in damage to the tensioner.





1. Remove the drive belt.
2. Position a 3/8 inch drive wrench on the drive belt tensioner arm and rotate the arm counterclockwise.
3. Move the drive belt tensioner through its full travel.
^ The movement should feel smooth.
^ There should be no binding.
^ The tensioner should return freely.

4. If any binding is observed, replace the drive belt tensioner.
5. Install the drive belt.
