@drvgfwdblds: Duramax Belt Squeal FIXED! Sticky Belt Dressing Goo Disaster 😱 2006 Silverado Duramax with that awful squeaking/chirping belt noise. Pulled the belt off and found the pulleys coated in nasty old belt dressing goo + a sticky belt. Hit everything with brake cleaner, wiped it down, and the noise is (mostly) gone… for now 😂 Never using belt dressing again!#silverado2500hd #whatsthatnoise #Duramax #LBZ #pavementprincess
