Alternator Denso or OEM Nissan

Replaced with OE spec brand new ones TWICE and it didn\u2019t fix the problem. Ended up buying a brand new Denso OEM on Amazon or eBay. I don\u2019t remember which and it fixed the problem for five years now.

Just replaced the original alternator on mine last weekend. Battery light came on while running errands, managed to get it home without issue. The next day battery was completely drained. Charged it up, as soon as I reconnected the battery terminals I had a 10 amp draw (car was off) and the alternator started smoking. Put a reman Denso in and all is well a week later.

Reman Denso from Advance thru WorldPak 210-1054. Same day, maybe 30 minute install. Never looked back and better than a used one with unknown history IMO!

just get a denso reman.

If you can go Denso, just go with that regardless of reman or new. The ACDelco will probably be fine, too.

Replace the alternator. The battery light indicates the battery is not being charged (due to bad alternator), losing power steering is also a sign of bad alternator as it provides the power for it to function. O'Reilly battery test also confirms this as battery should read 13-14V if it's being charged by the alternator. Recommend going with OEM alternator or name branded aftermarket like Denso which is the OEM supplier for reliability reasons. This should fix most of your issues.

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.

Your Denso alternator lasted 22+ years. It’s way better quality than cheap reman alternators out there.

I suggest either getting your OEM DENSO alternator rebuilt at a shop (costs like $60?) or picking up a low mileage used DENSO alternator from a junk yard (or eBay). The Amazon new ones are probably junk and can cause trouble down the line.

Could just be a crappy parts store alternator. I use Denso only for replacement.
