TERREPOWER formerly BBB Industries Alternator P/N:8266
TERREPOWER 13970 alternator for the 2001-2006 BMW 325Ci 6-cylinder 2.5L and other vehicles is a remanufactured unit that charges the battery and powers the electrical system while the engine runs. It is driven by the engine's serpentine belt.
A battery warning light, dim headlights or a battery that keeps going flat can point to a charging problem. These signs alone do not prove the alternator is at fault, since a worn drive belt is another common cause.
TERREPOWER 13970 is listed for a wide range of BMW models, including the 2001-2006 BMW 330Ci 6-cylinder 3.0L and the 2001-2006 BMW X5 6-cylinder 3.0L.
