At idle, from outside the vehicle, I sometimes think I'm hearing a noise like a squeaking idler pulley from my 6.0. It's tough to be sure because of all the diesel racket.

Is there an idler pulley or two that are known to be short-lived on six-liters?

Is the 6.0 an engine that "just makes that noise," similar to the Chevy 350 whistle?

Old thread, yes. but same problem. I have a squeak but it comes and goes. Some times soft I can only hear it when I walk in front of the truck sometimes I can hear it in the cab. I replaced the belt about 3k miles ago but problem still shows up. It shows up more when it is wet/damp outside. Truck sitting still or driving.

Any ideas on which pulley is most likely the culprit? the tensioner seems to have good tension.
Thanks in advance!
