Alternator AC DELCO or OEM Nissan

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.

Z1 Offroad has an OEM Nissan remanufactured for a good price, that's I what I went with.

Most of my experience is from the Infiniti side of the family, but I replaced an alternator on all my higher mileage vehicles. In general, the diode packs in Nissan alternators go out after about 150k miles or so.

If you don\u2019t have huge power requirements and are happy with the standard amperage then just grab an NA Z32 alternator from a wrecker and modify the tensioner bolt to suit.

I always get AC Delco from RockAuto... never had one bad out of the box... Can't really speak to any other brands.

My car started experiencing the same issue as yours. Randomly lose power, no acceleration, give jump start, two days later, the same issue. Had to have it towed to Nissan. Yes, long story short, it does need a genuine OEM Alternator and OEM Battery! For some reason, the 3rd party parts are not as effective in the product. Once placed in my Nissan, it was commented there have been no issues.

On rock auto I see new alternators from ac delco. Not sure about any of those brands.

I ended up replacing the alternator but it wasn\u2019t a genuine Nissan part and it didn\u2019t work.

So I go to get some iced coffee because Dunkin just came out with pumpkin and the car doesn't start. Sputters. So I call roadside assistance for a jump. They tell me it can't be jumped and it's probably my starter. Real kicker is I then call for a tow, tow guy shows up and jumps it???? So I HESITANTLY drive it to the dealer who determines it's a bad alternator.
