When a catalog match exists, replacement listings for this model year are linked through parts.autotk.com. This page does not invent compatibility.
The replacement link only appears when the catalog feed has at least one compatible product for this exact model year.
Mechanically related parts include starter, battery, serpentine belt. Similar symptoms can come from those parts or from the broader system, not only from a failed alternator.
Use the related-component links on this page when those combinations are published. A system-category NHTSA report is not proof that this specific part failed.
A failing alternator can be one of several causes of a battery warning light or a no-charge condition. That possibility is not a diagnosis of this vehicle.
Also consider battery and other system faults. Verify with testing rather than replacing parts from a list.
If the symptom remains after a alternator replacement, another cause — including battery — may still be involved, or the replacement may not have addressed the actual fault.
This is a diagnostic branch, not proof that the new part is defective or that the related part has failed.
