Alternator AC DELCO or Duralast

Possibly the alternator, mine did that so I bought a brand new duralast gold alternator and it solved so many of my problems.

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.

For hpw old your car is, and the price of these boys in the photo, id go to your local autozone and get their alternator, simply because they come with a lifetime warranty

IMO duralast doesn\u2019t last no where near as long as a good quality Bosch/Denso alternator.

Finally, ordered a duralast Alternator which is expected to be delivered tomorrow.

Believe it or not, though I installed a brand new alternator(Duralast gold) that turned out to be bad from the start and I had to replace it again(so I guess what I’m saying is check the tention on your belt, but don’t rule out the new alternator as - also - being bad), been 2 years since tho.

I purchased a Duralast 115A Alternator 14921 (remanufactured) which, once we moved the pulley and fan from old to new, it mounted up without a hitch. Once the battery was charged I connected everything up and she started right up. However, the voltmeter was hanging around 12V so we put a multimeter on the battery and only saw 12V+/-.

Wouldn't recommend AutoZone based on my experience. Had a duralast gold fail on me and had to get a replacement one.

Made the mistake of buying the duralast, first one lasted a couple months, and the second one is dying, only charging the battery at highway speeds, just like the first one before it died.
