TERREPOWER formerly BBB Industries Alternator P/N:11045
TERREPOWER 8303 alternator for the 2003-2004 Ford Expedition V8 4.6L or 5.4L and other vehicles charges the battery and supplies power to the electrical system while the engine runs. This remanufactured alternator is designed for dependability through the service life of the vehicle.
Dim headlights, a battery warning light or a battery that keeps going flat can mean the alternator is weakening. Before replacing it, look over the belt for cracks and glazing and the battery cable ends for corrosion, with the engine off. The engine takes one alternator.
It is a direct-fit alternator replacement for the 2003-2004 Ford Expedition V8 4.6L or 5.4L and the 2003-2004 Lincoln Navigator V8 5.4L.
