Detailed Description

WAI builds the 21393N as a new alternator assembly for vehicles that require dependable charging output and consistent electrical support. The unit uses an internal regulator and clockwise rotation, with a pulley already included for installation on the specified applications. Its 150 amp rating and serpentine belt compatibility make it a practical replacement for charging-system service on Volkswagen Atlas and Volkswagen Atlas Cross Sport models.

This part cross-references Gates (e.g., 21393) for the same application.

Common Uses
