This document is a scanned underhood decal showing serpentine drive belt installation/routing for Ford 5.0L and 5.8L V8 engines, presented in both English and French. The diagram illustrates the belt path around seven labeled pulleys: alternator (ALT.), tensioner (TENDEUR), A/C or idler (CLIM. OU POULIE FOLLE), fan (VENTILATEUR), power steering (P/S / DIR.), air pump (POMPE À AIR), and crankshaft (VILEBREQUIN). An illustration of a hand with a wrench on the tensioner accompanies the instruction to 'LIFT COUNTERCLOCKWISE USING IDLER PULLEY BOLT TO RELIEVE TENSION,' with the equivalent French instruction printed alongside. The bottom captions read '5.0L & 5.8L DRIVE BELT INSTALLATION' and the French 'PARCOURS DE LA COURROIE MOTEUR 5 L OU 5,8 L' (partially obscured by a torn corner). A Ford-style part number ending in 'TA-8B656-BA' is printed vertically along the right edge, though its prefix is cut off. A reader can learn the correct serpentine belt routing order for these engines and how to release belt tension using the tensioner bolt when installing or replacing the belt. The decal is undated and does not name a specific model year or vehicle.
