Installation Notes

Verify the vehicle’s original alternator amperage, pulley style, plug orientation, and mounting-ear clock position before installation. This Bosch AL0193N uses a clockwise rotation, internal regulator, and 6-groove pulley configuration, so matching the OE setup is important for proper installation. Confirm fitment against the vehicle’s build date where noted, especially for 2015 Volkswagen Beetle and Jetta applications with June 2015 cutoff requirements.
