Remy Alternator P/N:91530
Remy 12918 alternator for the 2008-2009 Pontiac G8 V6 3.6L charges the battery and powers the electrical system while the engine runs. This remanufactured Remy alternator has an internal regulator and an internal fan.
Dimming headlights, a battery warning light or a battery that keeps going flat can mean the alternator is weak. With the engine off, look over the drive belt and the battery cables for looseness or corrosion before you replace it, because a worn belt or a poor connection may be behind the symptoms. A shop can test the charging system itself.
