Product Q&A

If ordering alternator, how do I get a refund for the core charge?Janice D.Mar 16, 2022
Best Answer:Hi Janice, thank you for reaching out. Once you order the part, you will have a 30-day leeway to give us a call and set up a return forthe core. You will shoulder the shipping cost. Refund will take effect after the manufacturer finishes inspecting the core. You can use the link below to order the alternator while it's on sale. Have a good one. <a href="https://www.carparts.com/alternator/quality-built/mpa15431?can=cpab2020_20220316" target="_blank">https://www.carparts.com/alternator/quality-built/mpa15431?can=cpab2020_20220316</a>

Customer Reviews

Very pleased with the product. Fit perfectly and actually one of the easiest fix’s I’ve done. The only down side is I got charged for a the old core, they said they would provide instructions on how to send the old one back to them but no instructions were given on how to do so or where to send the old core.

Oe Replacement Qb Premium Alternator, Remanufactured
New like quality, fair price, great instructions.
Ordered one for my f150 almost a month ago and installed it a few weeks back. It was the easiest install for someone who’s never changed an alternator. Came in a nice clean box with labels and instructions. Nice quality and works like a charm. My truck runs and drives like it should. Definitely recommend this one for anyone who’s looking for a fairly priced alternator and doesn’t mind installing it themselves to save some money. I saved over $1000 by doing it myself. If anything changes I’ll be sure to update if anything changes.
