Product Questions & Answers

Q:Will it fit in a 2012 Buick lacrosse hybrid?
Tony
A:BEST ANSWERHi Franchot, I'm glad to assist you. No, it is incompatible. It is a universal type of alternator, not a direct-fit vehicle-specific part. You forgot to mention the engine size as well, which is very important to help determine the matching alternator. For us to check carefully and be accurate on the part you need, please provide the complete details of your vehicle (year, make, model, submodel, 2WD/4WD, and engine size). Still, it is best to call our parts specialist (for real-time, live, and immediate assistance) on our toll-free number, 1-866-529-0412 (Monday through Sunday). Show less
