GM Genuine Parts 23279588 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

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.

Like new was a challenge. I ordered one that was in the original box but was damage. When I received the item. The plug was broken. So I returned and they sent me a replacement. A low a behold this plug was broken on this one. So I decided I would try one last time. The third time was the charm. It was in perfect condition and almost half the price. You may have to buy another battery also. My truck is back in top shape. I'm happy.

While I trust ac delco brands, this was not packaged correctly, and I received it with a broken connector, had to return.

Works great on my Acadia! I am not giving 5 stars, because the item arrived with no hardware -- you need to use your old rusty bits to reassemble. The old nut which holds the power wire in place, is not a perfect match for the threads on the new alternator. When I reinstalled it, the nut "felt" tight to me, but did not properly seat, causing intermittent charging. After troubleshooting, I finally got it fully tight. This caused a lot of frustration, and I almost returned the unit before discovering the issue. Fifteen cents of fresh hardware would have saved me a lot of trouble....

Lasted longer than the buick did.

Exact fit and NEW, not remanufacured. Restored proper charging system operation. Great price!!!

Unit installed and working well.

Muy buena calidad, OEM
