TERREPOWER formerly BBB Industries 8318 alternator for the 2004-2008 Ford F-150 4.6L / 5.4L and other vehicles is remanufactured to charge the battery and power the electrical system while the engine runs.
Dimming headlights, a battery warning light or a whine from the alternator can point to a failing charging system. Before you replace the alternator, rule out a worn serpentine belt, a weak battery and loose or corroded cable connections, since any of them can mimic a weak alternator.
A 2004-2008 Ford F-150 4.6L / 5.4L takes one. This direct-fit replacement alternator also fits the 2006-2008 Lincoln Mark LT 5.4L and the 2007 Ford F-250 Super Duty 5.4L.
