Ford Fiesta Serpentine belt Problem

Do you have a belt tensioner? Serpentine belt? Check for a cut-out in tensioner or the arm, maybe 3/8 or 1/2 inch cut-out. If so use a rachet or break-over in the cut-out and pull to release tension.

This must be Ford export because my US database doesn't list a ford fiesta. I don't have information on this vehicle.
