I have a 2013 F-150 3.5L Ecoboost with a squealing noise I'm trying to determine what it is. It doesn't always happen but sometimes does when I first start the truck and seems to be coming down from the initial high-idle and sometimes a quieter sounding one when I'm driving and at pretty light throttle. I have a video of it where you can hear it around the six second mark.
