Detailed Description
WAI part number 41002N is an OE-style alternator for Subaru charging system service where a direct-fit replacement is needed. It is built as a new unit with proprietary components and processes, and it uses a serpentine pulley setup with clockwise rotation, internal regulation, and a decoupled clutch pulley. This alternator fits 2017-2023 Subaru Impreza and 2018-2023 Subaru Crosstrek applications listed in the fitment data.
The 41002N is a practical choice when replacing a worn charging unit on a Subaru Impreza or Subaru Crosstrek and when the vehicle requires the specified DENSO-family configuration. The 130-amp output supports the electrical load of today’s vehicles while maintaining consistent charging performance.
What It Is Used For
- Restoring charging output when the alternator can no longer maintain system voltage.
- Replacing a unit with bearing noise, pulley wear, or internal electrical failure.
- Addressing battery warning lights caused by charging system faults.
- Correcting low-voltage conditions that affect starting and electrical operation.
Installation Notes and Tips
Verify pulley style, rotation direction, connector layout, and amperage rating against the original unit before installation. Confirm fitment by model year and charging system configuration for the Subaru Crosstrek and Subaru Impreza listed above. Part number 41002N should be matched to the vehicle’s original alternator specifications for proper installation and operation.
Quality Assurance
WAI states that this alternator is 100% new and manufactured with proprietary components and processes to support long service life and performance. Part number 41002N cross-references BBB Industries 41002 for the same application.
