Alternator OEM Toyota or OEM Nissan

I just had to replace original alternator in my 213k mile 2017.

I legit daily drive an 03 camry, the only thing that needed changing in my 2 years of owning it was the alternator.

I did one on my Wife's 2011 Nissan Quest with the same engine as the Pathfinder.

Original one lasted around 130k miles, so can't really complain.

The one on the Quest wasn't great, but I think I got it done in about 4-5 hours.

Had to pull the lower bumper splash shield, and the passenger fender liner.

Then I unbolted the ac compressor and let it drop down (was able to leave all the refrigerant hoses connected so that was a plus).

The upper bolt was a pain to get to, probably the worst part of the job!

With it unbolted there was just barely room to get it out through the wheel well. If you had it positioned just right it would slip through the opening between the subframe and the frame rail.

For any other car it would be replace but it's a Camry, those items especially water pump and alternator generally needs replacing at 220k but as long as you replace them with OEM Toyota parts you'll be good for years to come.

I\u2019m 43 and only have had 3 cars in my life only Corollas and Camry. I get a new one around 250k miles. They are great reliable cars that run well with basic maintenance. Only wear and tear items have I ever replaced with the exception of an alternateer on one of my corollas at around 200k miles. As long as I can keep going to 250k I will keep buying them.

My last OEM Toyota alternator made it to 250K miles. My future non-Toyota ones failed because they were cheap remanufactured ones and later I found a failing harmonic balancer that was putting extra pressure on bearings of the alternator

Did this years ago in my 5th gen, not because of more Amps, but because for some dumb reason the Alternator for the Celica was $250 reman (back in 2014), but Camry's in the Junk yard with Good OEM Alternators were plentiful. That was after I had 3 reman alternators fail in less than 6 months, 2 being DOA!

And assuming that the alternator is the issue, hope you get an oem good part or a used one, on nissan altimas/maxima Remans are bad.

I've gone through 3 Nissan Value Advantage Alternators (through the Infiniti dealership - warranty) for my Q. All Infiniti offers for my year (2015) are Remanufactured Alternators. I'm tired of Remans.

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.
