Bosch Alternator P/N:AL559N
Bosch AL4319X alternator for the 2014-2016 Subaru Forester H4 2.5L and the 2014-2018 Forester H4 2.0L is a remanufactured unit that charges the battery and supplies power to the electrical system while the engine runs.
Dim lights, a battery warning light or a battery that keeps running down can mean the alternator is not charging fully. Before replacing it, look over the drive belt and the battery terminals with the engine off, since a slipping belt or a loose, corroded terminal can look like a bad alternator.
This alternator fits the 2014-2016 Subaru Forester H4 2.5L and the 2014-2018 Forester H4 2.0L; each takes one, and the alternator is designed to be identical in fit and performance to original equipment parts.
