This is a bilingual (English/French) underhood data/specification decal from a Ford vehicle equipped with the 4.6L engine, photographed on what the uploader identifies as a 1998 Mercury Grand Marquis. The label contains four cautionary sections and a serpentine belt routing diagram. The air conditioning caution specifies an R-134a refrigerant system with a maximum operating charge of 1.08 kg (2 lb 6 oz), refrigerant oil meeting Ford spec WSH-M1C231-B, and compliance with SAE J639, warning that service should be done only by qualified personnel. A second section explains the vehicle has electronic fuel injection with a fuel pump shut-off (inertia) switch that can prevent starting or cause stalling if tripped, directing readers to the Owner Guide for reset instructions. A warning section prohibits tampering with air bag system wiring. The right side shows the 4.6L drive belt installation diagram, with the belt routed around the alternator, idler pulley, water pump, tensioner, A/C compressor, crankshaft, and power steering pump. The bottom bears the Motorcraft/Ford branding recommending Motorcraft spark plugs, filters, and tune-up parts, with a partial part number beginning F5AE-19. A reader can learn the A/C refrigerant charge spec, oil spec, and correct serpentine belt routing for the 4.6L engine.
