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.
Nissan use to be good
The alternator quit on my 2020 Nissan Sentra, and there were NO aftermarket options for it. The dealership wanted $900, JUST for the alternator, so I can actually believe their price.
Had one do this on me and it was the alternator.
Alternator stopped charging while driving and it slung grease all over the engine bay and hood.
oddly enough, I've only ever been completely stranded by failed alternators. once in my '98 Jetta GLX VR6 and once in my '09 Outback 3.0R
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.
4 aftermarket alternators in a Volkswagen Vanagon… after the last shit the bed i insisted on a factory one. That solved the charging system issue.
When I finally bought another car and started preparing the Bora for sale, the alternator failed. The only real issue it ever gave me.
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.
