Cummins 6.7 engine squeal/squeak on startup
I'm starting to get a constant high pitch squeak after just starting the engine. It seems to go away after driving for some time, as I don't hear it after stopping from driving to our destination. ...

Mine has been doing the same thing since new. I had it back to Cummins and they replaced the Serpentine belt, as well as using a special laser belt alignment tool. Unfortunately neither helped. It is now more than 100K miles, and it still does the same exact thing. It always starts up squeaking, but it goes away after a few miles. It is annoying, but I have learned to live with it. I carry a spare serp belt just in case. 2010 Discovery
