Specs At A Glance

Good To Know

Q: How do I know my alternator needs replacing? A: A battery warning light, dimming lights, or a battery that keeps draining points to a failing alternator. A charging system test confirms the diagnosis before ordering.

Q: Does the belt need to be replaced at the same time? A: Inspecting the serpentine belt is wise whenever the alternator is swapped. A worn belt can slip on the new 6-groove pulley and cause charging issues.

Slight variation in finish or dimensions may occur between production runs, and fit can depend on serial number, so confirm compatibility before ordering.
