2010 Nissan Altima 2.5s perfect replacement.
The TRQ Alternator was the perfect replacement for my OEM alternator if 219k miles. Battery stays consistently charged and no more gurgling sound heard from inside the car when driving at near idle speeds.

Ive had it in got about two weeks now and haven't had any issues. I bought a used '09 Altima that was in rough shape, and I've used 1Aauto and TRQ brand suspension and ignition, and even some fuel system parts since i started working on this car a year ago, and Every Single Part has been reliable and quality material. I recommend this website and products to everyone i talk to! 15/10

So I don't have to use tension when removing the belt?
You have to relieve tension from the tension pulley. There is a bunch of YouTube videos that can show you how.
