Yes. 12 month/ 12,000 mile warranty on the part only

Is it same with my alternator (hummer h3) : gm p/n 15946765. 14v. 120a. 2650682 0. 170220033434. tg12s047. valeo. ncc572bxdwa.

I really don´t know, but your VIN should allow you to see your parts description and from there you may ask if it corresponds.

Is this the right alternator for my Hummer H3 2007? Motor: 3.7 5 cilinders.

Cesar, I really don't know, I bought it for my Chevrolet Colorado, look for the part you need through your vehicle VIN

Fits 2007 Colorado

Fit my 2007 Chevy Colorado 2.9L 4cyl 2WD. Easy install. Install tip: remove the fan shroud and remove alternator by pulling toward the radiator. The fan shroud is only clipped on. Separate the clips with a long flathead screwdriver and remove the top half and ring of the shroud. De-tension the serp belt. Then unbolt the A/C hardline bracket. 2 screws in front, 1 on the side. Unbolt the alternator, all 3 on the side. You may have to GENTLY push the A/C hardline to the side to make room to extract the alternator past the fan blade. Wiggle around, it WILL come out with proper angling. Good luck to anyone going through this.

Works great, no issues

No problems at all. Charging correctly and quietly. Easy install. Recommend remove battery, battery box, fuse box and the bracket that holds the ac line in place. It's tight, but easiest way to remove and replace. 2007 hummer h3
