2010 5.4 squealing
Hi guys I've got a squealing noise coming from the engine on my 2010 F150 5.4 4x4 160k miles.
The noise happens anytime the engine is reved passed 3200 rpm. Hot or cold, driving or parked it doesn't matter, the noise sounds the same. I took the belt off, reved the engine and the noise went away. Belt dressing made no difference, but while flushing the radiator and getting the front of the engine wet, the noise went away until everything dried up.
The tensioners feel smooth, belt looks ok, power steering pump and alternator pulleys feel ok too but I can't really tell if they're good or not.
Here's a video of the noise. What do you guys think?

Thanks everyone!
