Engine squeeling after high idling or under load.
When truck has been high idling for say 10-15 minutes in hot weather and I leave it sounds like the engine fan is on and then when I accelarate it makes what seems to be a metal on metal squeeling or even a loose belt noise. I have also heard this noise when towing and fan comes on then if I accelarate the squeeling noise starts again. It does not make noise for long maybe 5-10 seconds. Any suggestions ?

Hmmm, I've let mine idle that long but I'm in WV...not exactly a hot weather haven, and have not experienced that kind of problem.
How many miles do you have on yours?
I've got an 03 F250 6.0 King Ranch crew cab, auto, 4x4, 3.73 16" wheels with 45K miles on it....no sunroof and mines Emerald Green w/tan.

Sounds like the electro-mechanical clutch to me. I have the same noise and am taking it in soon. Only happens when fan is partially engaged huh.

I think I've got the same problem. I'm pulling 18,000 lbs of fifth wheel. When I get in the hills, here's what happens:
The truck downshifts.
The fan clutch kicks in.
As I get to the top of the hill, the truck shifts back into overdrive (5th).
The fan is still running.
Right before the fan stops, it sounds like an old-fashioned telephone ringing somewhere under the hood.
When the ringing stops, the fan clutch has disengaged.
This only happens when I'm running up and down hills with the trailer. The gauges never move to indicate any overheating condition or even a rise in temperature at all.
I'm thinking fan clutch or idler pulley?
