Installation Notes and Tips
Verify the original alternator amperage, pulley style, connector style, and rotation before installation. This unit is listed for Bosch 150- to 160-amp applications in several GM truck and SUV platforms, with some listings supplied as 150 amp where the original vehicle used a 160-amp unit. Confirm the vehicle’s charging-system configuration against the fitment notes before ordering.
For best results, inspect the belt, battery condition, and charging cables during replacement. A worn serpentine belt or weak battery can affect alternator performance and diagnosis.

WAI states that this alternator is manufactured as a new unit using proprietary components and processes to support maximum life and performance. The 11075N is built for charging-system service in demanding GM truck and SUV applications, including Chevrolet Silverado, GMC Sierra, and Cadillac Escalade platforms.
