Alternator OEM Volvo or AC DELCO

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.

Personally the AcDelco would be my top choice here with these options going new and not a reman.

If those are your only options you're gonna go with, Remy or ACDELCO. Keep in mind the ACDELCO is not made by ACDELCO and is just rebranded. But has a warranty and decent support.

I know my 2005 S60 alternator has a chip in it that is necessary to talk to the car's ECU so be careful buying aftermarket.

Honestly, even the AC Delco quality is questionable.

ACDELCO because if I get another API alternator that’s defective I’m going to kill somebody

I got this message when the mechanic replaced my alternator with a non-OEM unit that didn't have a voltage regulator.
