You are lucky, I have been to two Ford and two Lincoln dealers and also
talked to a tech on Ford's factory hot line and was told this is normal.
I have the same fan clutch as in your 06 and mine sounds like a jet
aircraft when starting out in the morning, it will go away in about 30
seconds and this is on a cold engine. Lately our temps have been in the
high 90's to over a 100 degrees and that fan just drives me nuts. My
neighbor has a Chevy 4X4 SUV and it makes the same noise only louder.
The new engines run hotter and need larger fans and fan clutches.
