Detailed Description

Installation Notes and Tips

Verify the original alternator amperage rating and build date before ordering. For this listing, the 2011 Corolla application is noted from 12/2010, so production timing matters. Confirm belt alignment, electrical connector style, and mounting points against the removed unit before installation. Part number N11577 should be matched to the vehicle’s charging-system specification, especially on Toyota Corolla and Toyota Matrix models.
