Rotational whine after engine turned off
I didn't notice this till a raptor owner brought it to my attention a few months ago when he asked me if I had this whining noise after I shut off my engine. I said i didnt or atleast I didnt think i did. When I shut off the truck sure as **** there it was. It last's maybe a second or 2 more then the actual engine running and it is definitely something rotating. It sounds more like a whistle then a whine. Im going to try and get it recorded so people understand what I mean. Also, this is going to sound absolutely crazy. But while going through a short tunnel and under acceleration I heard a loud whistling coming from the engine, similar to the whistle of a turbo and it changed pitch as I gave it gas or let off the pedal. Now i have no clue if the 2 noises are related or not.
Lastly i've started to experience an antifreeze odor coming from the engine at idle. I've checked all hoses, hose connections, reservoir and cap and cannot find any leaks whatsoever. I've never had this issue since owning with 4 miles on it, 24k on it now.
Truck is a 2014 f150 5.0.

Have you taken it to the dealer for these issues?

Radiator cooling fans (?). *Though they usually spin-down soon after the ignition is turned-off.
