Detailed Description

Bosch AL4322X alternator is engineered for Subaru charging-system replacement where the original unit has failed or output has dropped. This remanufactured alternator is built around a 180 amp design with a 12-volt electrical system, internal voltage regulation, and clockwise rotation. The included pulley and 6-groove configuration support the specified belt setup for the listed vehicles.

This part cross-references Subaru OE numbers 23700AA91A and 23700AA91B for the same application. It is a practical replacement choice for drivers searching for a remanufactured alternator for 2015-2020 Subaru WRX, 2015 Subaru Outback, 2015 Subaru Impreza, 2015 Subaru Legacy, 2015 Subaru XV Crosstrek, and 2017 Subaru Outback applications.

What It Helps Address

  • Battery warning light caused by alternator output loss
  • Low charging voltage during driving or idle
  • Dim lights or unstable electrical performance
  • Battery drain from a failing charging system
  • Noise or belt-related issues tied to a worn alternator assembly

Installation Notes and Tips

Verify pulley groove count, rotation direction, plug clock position, and mounting-ear orientation before installation. This AL4322X uses a rear-view main mounting ear position at 6 o’clock and a 5 o’clock plug clock reference, so matching the original unit is important for proper fitment. Confirm belt alignment and charging-system connections during replacement.
