| Bad squealing.... I hear bad squealing after I turn the truck on. 08 3500HD Sierra. Keeps on squealing loud for a few minutes, then gets quieter, but I still hear it. Belts? What to look for? New to diesel. Thanks.

| I had the same problem recently. Was doing it for a few weeks, hoping it would go away. I changed the belt, and now I'm squeak free.

| I'd say belt, but you can check by just putting a dab of break fluid on the inside of the belt after it has run and with the truck turned OFF, then start it again, if it calms the noise you need a new belt. |

| If you do replace the belt, always include a new tensioner and idler pulleys as well.  They're cheap, belts aren't.

| Resolution to the problem. It was a belt. Got new one on and all squealing gone.
