Reviews of AC DELCO alternator

ACDelco makes a brand new alternator for $95. They were the OEM for GM.

I went with RockAuto as well, but went with the AC Delco Gold Reman that was wound to have 135 Amp output instead of the OEM standard (~110 I think) I want to say it was around ~$170 with a $45 core deposit. AC Delco is a solid name in parts, and I believe was reman'd in Mexico.

I got 3 AC Delco remans from RA before they refunded my money and refused to send a 4th...The third they sent arrived fine but lasted 37 miles on the car before the front bearing locked up. Over a month of headache and ended up buying a Tuff Stuff alternator.

i had an equinox do that to me. Kept eating alternators. They were new AC Delco ones too. I just got a used OEM one and has been fine.

On that list, I'd only go with the AC Delco.

Only brand here I am confident with is ACDELCO, Wai I’ve installed due to customer already having the part but I cannot swear to its reliability.

AC Delco makes a good product. Alternator technology is really old, so it's not difficult to do right.

I have the acdelco in my old Comanche and it works great.

Honestly, even the AC Delco quality is questionable.

I got an ACDelco reman alternator from RockAuto, but it has a grinding feeling and bearing noise when I spin the shaft by hand. I'm not putting that "reman" alternator in the car only to have it fail a few weeks from now.
