2010 Buick LaCrosse Alternators

Genuine GM alternators for the 2010 Buick LaCrosse, at wholesale prices. Alternator output rating varies by electrical load, so a truck with a tow package or upfit wiring takes a different unit. Epsilon II from 2010 to 2016 and a lighter redesign from 2017 to 2019.

When to replace

A battery light, dimming headlights at idle, or a no-start after a short drive. On a full-size car, trim and package content split these part numbers in ways a diagram will not show.

Why order factory

• We catch the wrong part before you do. VIN verification is free on every alternators order.
• Fast out the door. In stock alternators ship within hours, not days, from Dallas.
• No hassle returns. If the alternators is not right, send it back.
• Warranty intact. OEM alternators keep coverage that an aftermarket part can void.
• Wholesale pricing. Most alternators numbers land well below dealer list.

Avoiding the wrong part

Materials and coatings are specified, not approximated, which is why factory parts last through more heat cycles. Check the VIN before ordering anything that has to bolt to something else. Shipping is calculated on real weight and distance, which usually beats a padded flat rate.
