2015 Yukon Denali starter replacement 

Took me 2 hours. Forgot to unhook the battery. That was sparking. Thanks for the tutorial.

Mi gente nunca aprieten eso con la pistola de impacto es aluminio la base y si daña la rosca el trabajo va a ser el doble

Why would you pause the video where you removed the negative battery terminal? That's a KEY first step. Then you spliced it out of the video when you reconnected it. Gonna get someones hurt

Any issues with starting since replacing it? I'm experiencing the same issue on my 16 escalade. Changed the battery and negative cable. Thanks
