Owner reviews for alternator

I recently purchased parts from NAPA. Got a Denso reman alternator, water pump, and belt tensioner.

Original starter and alternator

Buy off rockauto and go with denso brand

First gen Expedition- I'm not a Ford fan, but some of those old Expeditions were amazing. Definitely seem to be hit or miss, either bulletproof or a nightmare with no in between. My father had a 98 that he bought new and scrapped in 2019 with just shy of 500k miles, absolutely beat the living shit out of that truck and it just wouldn’t die, only ever needed an alternator, 2 shifter cables, a brake hose and 2 ignition coils.

Alternator is easy. OEM or Denso for sure. It’s a super easy job.

FWIW when I had to replace the alternator on my 2008 last summer, the dealer only had OEM Toyota remans. The first one had a bad regulator or something and was clicking like crazy out of the box. They exchanged it no questions but said that's nearly never happened. Next one has been fine.

Get a denso reman or be prepared to replace it again in a year.

Duralast are shit alternator. See it time and time again people buy them and have more problems afterwards.

I have a Porsche 924 2.0l 125hp NA. I had already upgraded it to a Ridex 90ah alternator but it died within a few months.

My alternator in my 2007 V6 RAV4 died just under 2 years ago (Dec 2023), and I got it replaced at a local Toyota dealership. Now, about 20k miles later, I needed a jump start 2 days in a row, and O'Reilly Auto Parts battery tester said the alternator is dead again. Most sources say replacement alternators should last 5-10 years.
