Squeaks

[Waterdog]

My truck makes a squeaking sound at start up. Sounds like A belt or pulley. I don’t think it’s all the time but I heard it twice now while the truck was idling.

I had experienced this at start up in cold weather. But it wasn't constant. There's another thread about it somewhere. Maybe its the same thing.

My truck makes a weird squeaking metallic type sound on start up too but I have read many posts on it and it all says normal. I think there was a TSB about the way mine sounds and GM said normal dont attempt repair. ITs the same sound I get when I am coming to a stop just on a larger scale.

Any resolve with this issue? Having the same problem and it’s driving me crazy.
