This is a photograph of the factory serpentine drive belt routing decal mounted on the fan shroud/engine area of a Ford truck, uploaded to a 1988 Ford Bronco gallery. The bilingual (English/French) label shows the accessory drive belt routing diagram for the 5.0L or 5.8L engine, as stated in the French caption 'MOTEUR 5, L OU 5,8 L'. The diagram identifies the pulleys in the belt path: alternator (ALT.), idler pulley (IDLER / POULIE FOLLE), fan (VENTILATEUR), A/C or idler, crankshaft (VILE-BREQUIN), air pump (POMPE À AIR), and belt tensioner. Red instructional text explains how to release belt tension: in French, 'POUR DÉTENDRE LA COURROIE, AGIR SUR LE BOULON DU GALET TENDEUR ET SOULEVER DANS LE SENS INVERSE D'HORLOGE' (to slacken the belt, use the tensioner pulley bolt and lift counterclockwise). The English equivalent is partially cut off but references turning the tensioner pulley bolt counterclockwise to release tension. An illustration shows a hand using a wrench on the tensioner bolt. A rusted blue circular cap obscures the center-right portion of the label, hiding part of the routing diagram and caption.
