Part Description
This Grade A alternator was removed from a 2011 Buick Enclave equipped with the 3.6L V6 engine. The part was carefully extracted from a 120,000-mile donor vehicle and has been thoroughly inspected by our experienced technicians. This OEM alternator is currently on our shelf and ready to ship immediately upon order.
The alternator is a critical component of your vehicle’s charging system, responsible for converting mechanical energy from the engine into electrical energy to power your vehicle’s electrical systems and recharge the battery. Common alternator failures include worn brushes, faulty diodes, or bearing wear that can cause charging issues, dashboard warning lights, or complete electrical system failure. Replacing a failing alternator promptly prevents potential battery drain and stranding.
