Bosch Alternator P/N:AL0801X
Bosch AL4303X alternator for the 2009-2010 Subaru Forester H4 2.5L and other vehicles charges the battery and powers the electrical system. This Bosch alternator is remanufactured.
A battery warning light, dim headlights or a battery that keeps going flat can mean the alternator is not charging, though a slipping belt or a corroded battery terminal can produce those symptoms too. With the engine off and cool, look over the belt and the terminals first; if the alternator is the cause, this one replaces it.
This alternator is listed for a wide range of Subaru models, led by the 2009-2010 Subaru Forester H4 2.5L. The same unit as an alternator for the 2006-2010 Subaru Impreza H4 2.5L and the 2005 Subaru Outback H4 2.5L is listed too, and each takes one. Open the "Vehicles it fits" section to check your exact model and engine. It is designed to be identical in fit and performance to original equipment parts.
