when i start my f250 it makes this super loud high pitch squeal from 2-10 seconds and then goes away. i would not have realized anything if it wasent making a noise cause everything seems ok but it only does it some times.

thanks so much for any help or input!!!!!

TSB = Technical Service Bulletin - It's a write up to tell the technicians how to address an issue.

The squeal is probably caused by the belt slipping on a pulley. Eventually, it will wear out the belt. The squeal goes away when the pulley and belt are moving at the same speed.

If the truck is still under warranty, I'd have Ford fix it!

Mine would do it all the time, the dealer changed the belts and now it is fine. The only time it chirps now is after it has been sitting in the hot sun for hours and hours. It was really bad on mine before they changed the belts. There are two, one main drive belt, and one just for the A/C compressor pulley.
