Duramax Sixth Generation: 2017-2019 (L5P)
I have a 17 Crew with 44k on it , truck just started squealing. Dealer has changed belt and all moving pullys. They say it's not the fan either... They have scoped everything for the noise, they can duplicate it, but it goes away to quick. I have a video of it , not sure how to add it. Any help...
