Bosch Alternator P/N:AL4318X
Bosch AL8835X alternator for the 2006-2009 Chevrolet Impala V8 5.3L and other vehicles charges the battery and powers the electrical system. It is a remanufactured unit with a 6S pulley type.
A battery warning light, dim headlights or a battery that keeps going flat can mean the alternator is not charging. A weak battery behind the same symptoms is also common, so these signs alone do not prove the alternator is the problem. If the alternator is the cause, this unit replaces it.
This alternator is listed for a wide range of Chevrolet, Buick and Pontiac models, led by the 2006-2009 Chevrolet Impala V8 5.3L, the 2008-2009 Buick LaCrosse V8 5.3L and the 2008-2009 Buick Allure V8 5.3L. It is designed to be identical to the original equipment alternator in fit and performance. If your car is not named here, look it up in the "Vehicles it fits" section by year and engine.
