To maximize the engine performance, inspect the
belt for wear and for cracking. Replace the belt if the
belt is worn or damaged.

The belt must be replaced if the following conditions
are present.
• The belt has a crack in more than one rib.
• More than one section of the belt is displaced in
one rib of a maximum length of 50.8 mm (2 inch).
During replacement of the belt check the automatic
