Installation Notes and Tips

Verify the original alternator amperage, pulley style, connector type, and plug clocking before installation. This AL8782X uses a 6-groove pulley, clockwise rotation, and a rear-view main mounting ear position at 6 o’clock, so matching the original unit is important for proper fitment on Chevrolet Silverado 1500, GMC Yukon, and related GM applications.

Inspect the belt, battery condition, and charging cables during replacement to avoid repeat failures. Confirm the vehicle’s original equipment notes, especially on 2005-2007 GM trucks and SUVs with 160-amp alternator specifications.

Quality Assurance

Bosch remanufactures this alternator to support dependable charging performance and consistent electrical output. The unit is boxed for service replacement and built with the construction details needed for OE-style fitment on the listed GM applications.
