• Description:

  This genuine Ford accessory drive belt, base number 8620, transfers power from the engine crankshaft pulley to the belt-driven accessories on current-generation E-Series Super Duty vans, turning components such as the alternator and other engine-driven equipment. The belt wraps the pulley system and must grip without slipping so the accessories spin at their designed speed and the charging and accessory functions stay reliable. As a wear item that flexes through millions of cycles, it stiffens, cracks, and glazes over time, which is why a worn belt squeals, slips, or frays. Owners replace this belt when they hear belt noise on start-up or under load, see cracking or missing ribs on inspection, notice charging or accessory problems traced to belt slip, or are performing scheduled maintenance. Built to Ford specifications for this engine and accessory layout, the belt provides the correct length, rib profile, and construction for proper tracking and grip. This belt fits the configuration without dual alternators, so confirm the engine and accessory arrangement before ordering, since belt routing and length vary with those features. Inspect the tensioner and idler pulleys while the belt is off and replace them if worn, route the new belt per the diagram, and confirm correct tension and tracking. After installation, run the engine and verify quiet, slip-free operation across the accessory drive.
