i got a response last question about this. It whistles when i turn the engine off, just for about 15-20 seconds and then stops. The truck only has 50 miles on it and hasnt been used except for me. Ive heard its the AC equalizing things. This isnt something to worry about is it? everything normal?
 
The ac system equalizing sounds feasible. If you have any doubts, ask the service manager at the dealer you purchased it from.
 
if you can duplicate it every time take it to ford just to be sure, they can listen and check diagnostics at no charge to you. does it have a turbo? does it do it when good looking gals pass by?
