Our take on the New Alternator For Subaru Legacy 2.5L 2010-2012, Outback 2.5L 2010-2012 11409n

This is a 110-amp replacement alternator for the 2.5L four-cylinder Subaru Legacy and Outback from 2010 to 2012. It uses a clockwise rotation and an S6 six-groove pulley, matching the factory belt layout on those engines. It is a direct-fit option for owners facing a failed or weak original alternator, and it cross-references Subaru part numbers A003TG6191 and A003TG6191ZC. Compared with a dealer remanufactured unit, it is a straightforward swap for the same mounting and wiring, so the main thing to confirm is engine size and model year before ordering.

Questions and answers

Will this fit my 2011 Outback 3.6R?
No. It is listed only for the 2.5L four-cylinder Legacy and Outback from 2010 to 2012. The 3.6R six-cylinder uses a different alternator.
How do I confirm it matches my original alternator?
Check that your car is a 2.5L from 2010–2012 and that the original unit has a six-groove pulley and clockwise rotation. The part cross-references Subaru numbers A003TG6191 and A003TG6191ZC.
Is 110 amps enough for added accessories?
110 amps matches the stock output for these 2.5L models. It handles normal loads, but a large stereo amplifier or winch may push it near its limit.
Does it come with a new belt?
No belt is listed. Reuse your existing serpentine belt if it is in good shape, or replace it while the alternator is off.
Do I need to disconnect the battery before installing it?
Yes. Disconnect the negative battery terminal first, then remove the belt and mounting bolts. Reconnect the battery only after the wiring is secured.
