DRIVE BELT ROUTING 1991-92 ENGINE COOLING BELT ROUTING BELT ADJUSTMENT Tensioners may be used to automatically adjust belt tension to specification. Check belt for fraying. If fraying exists, ensure both belt and Fig. 1 . Tensioners may contain a belt-wear indicator. See Fig. 2 . If tensioner reaches travel limit, as indicated by marks on tensioner, replace belt. Ensure serpentine belts are properly installed. See Fig. 3 - Fig. 7 . On models without tensioners, ensure belt tension is within specification. See BELT ADJUSTMENT SPECIFICATIONS table.
