pulley squeak

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?

5 years, 58,000 miles. Original accessory drive belts.

Do a search on belt squeal. From what I found the water pump pulley can cause this. I think there's an updated pulley available. I've had this problem for the past year including replacing the belt and it's still there, although worse in the winter. I'll get it looked at eventually.
