The V ribbed fan belt used in your engine requires the tension be
adjusted more accurately than is required with conventional V belts.
Inappropriate tension could cause the belt to make noise or break.
When the fan belt is damaged, electricity is not properly generated
or becomes a cause of engine overheating. You must check the
tension of the fan belt carefully.
