Drive Belt Tensioner: Description and Operation
Drive Belt Tensioner-Automatic
The drive belt tensioner will maintain correct belt tension if the correct length drive belt is on the engine. To verify that the drive belt tensioner is
working correctly, check to see that the belt length indicator mark on the drive belt tensioner is between the minimum and maximum marks. Remove
the drive belt and rotate the tensioner to verify that the tensioner does not stick, grab or bind. If the tensioner exhibits any of these conditions, install a
new tensioner.
