So before I left to go offshore last month, the truck started making a whine-like noise when stepping on the gas and decelerating. I got home yesterday after a 500+ mile trip and popped the hood, I couldn’t believe it: my drivers side pulley wheel (sorry don’t know what to call it) on serpentine belt was not moving! The belt had been running over it through the grooves but no spin. I loosened the nut just a little (15mm size socket) and just a touch of wd40 on the bolt/washer. Cranked her up and still have the noise, despite the pulley wheel now spinning freely. Taking it to the dealership today to try to diagnose it since all systems seem fine on dash/onstar. At least goin to get a new belt put on and buy a spare to keep in the truck.
TLDR: weird noisecoming from engine. Thoughts or insights welcome.
