This document is a scan of a factory underhood serpentine drive belt routing decal for Ford 5.0L and 5.8L V8 engines, printed in both English and French. It shows a schematic diagram of the accessory drive belt path around seven pulleys: alternator (ALT.), belt tensioner (TENSIONER/TENDEUR), fan (FAN/VENTILATEUR), A/C compressor or idler pulley (A/C OR IDLER / CLIM. OU POULIE FOLLE), power steering pump (P/S / DIR.), air pump (AIR PUMP / POMPE À AIR), and crankshaft (CRANKSHAFT / VILEBREQUIN). An illustration with a red arrow at the top shows a hand with a wrench on the tensioner, with instructions to lift counterclockwise using the idler pulley bolt to relieve belt tension when installing or removing the belt. The decal is titled '5.0L & 5.8L DRIVE BELT INSTALLATION' (Parcours de la courroie – Moteur 5 L ou 5,8 L). A Ford part number, E87TA-8B658-BA, is printed vertically along the right edge. A reader can learn the correct serpentine belt routing for an air-pump-equipped 5.0/5.8 engine and the correct method for releasing tensioner pressure during belt replacement.
