Will this fit my 2004 Outback H6 3.0L?

It is listed for Outback H6 3.0L models from 2001 to 2005. Confirm your engine and model year with the part finder before ordering.

Does it match the original alternator?

Yes. It replaces OEM part numbers 23700-AA401 and A003TB1891, with the same 100-amp, 12-volt output and six-groove pulley.

Is it new or remanufactured?

It is sold as a new alternator, not a rebuilt core.

What is the pulley setup?

It has a six-groove pulley with clockwise rotation, matching the factory belt drive.

Is it an upgrade over the stock alternator?

No. Output is the same 100 amps, so it restores stock charging rather than adding capacity for extra accessories.

Our take on the OEG Parts New Alternator Replacement for Subaru Outback H6 3.0L 01-05

This is a 100-amp, 12-volt replacement alternator for the 3.0L H6 Subaru Outback from 2001 to 2005. It uses an internal regulator and internal fan design with a clockwise six-groove pulley, matching the factory fitment and the OEM part numbers 23700-AA401 and A003TB1891. It is a direct-fit remanufactured-style unit for owners chasing a failed charging system, not an upgrade. Compared with dealer OEM units it is a budget alternative; the trade-off is that rebuild quality varies, so buyers should check the pulley and connections before installing.
