GM Parts Newly manufactured as an exact replacement for your vehicle's original alternator

Fit perfect but a pain in the butt to install. But product otherwise was great . On the traverse I installed it in really needed 2 people. 2 hour install time

Unit installed and working well.

Muy buena calidad, OEM

4 Stars due to packaging. First unit arrived with multiple holes in the side of the box. Hardly any protection for the alternator. Upon closer inspection, I found that the protective plastic ring around one of the electrical connections was broken off (found it at the bottom of the box). Had to return that unit and order a new one. Second alternator came unbroken. Installation is a royal pain in the rear, but that's not the parts problem. I'm as shade-tree mechanic as they come and I did it successfully. I came at it from the top (they say that you can remove it via the right tire well, but I think that must be for non-AWD models). It takes some playing around with the geometry, but it will eventually work. I would HIGHLY suggest wrapping bungee or rope around the unit and having a second person keep tension while you remove the posts and bring it out of the engine. New unit has worked fine for a month now. Should be an easy fix, but Chevy can't allow that!!!!

Installed in a 2012 Chevy Traverse. Takes about 2 hours, first time doing this job. Old alternator can be removed by passenger side fender, remove tire and internal fender guard. You will need to play a little Tetris but it comes out, no need to remove coolant reservoir or power steering cables like in some YouTube videos that removed from the top of engine.
