My brand new 2002 F-250 SD CC XLT 4X4 V-10 has developed a whistling noise in the engine compartment. It only happens on cold mornings Less than 40F). It appears to be coming from an accessory, not the engine proper. It starts and stops just like a train whistle and has a similar pitch. After about 6 miles of driving it disappears. On the evening commute home, there is no whistling sound. Any ideas?
I'm expecting Johnny Cash to start singing any moment.
power stroke goes into a preheat mode when it is cold. will kick out of this mode if the brake or throttle is touched. does it quit if you touch the pedel?

I don't know if it is relevant bu tthere are TSB concerning belt whine during cold starts on the V10's. Some are more pronounced than others. It could be the problem. I'd also check ALL the fluids, sounds like after it heats up (or fluids expand) it goes away.
Also, you may have got the optional train whistle that is included in the railroad package, for free.
I agree with NoMo, take it back...it ain't normal.
As a follow-up, the dealer determined that the whistling sound was due to overspray of paint on the surface of the idler pulley where the serpentine belt rides. I think they used some scotch-brite to clean it. The dealer used a FORD Hotline to come up with this fix. No whistling this morning, but then again we haven't had much cold weather here in southern NH.
The main reason I had brought the truck in was due to a leaking lower radiator hose. The clamp was not holding. I took a pair of channelocks to squeeze it open and attempt to reposition it, thinking that was a simple problem to fix. However, the clamp snapped. The material appeared to be very brittle. The dealer said they have had some problems with the hose clamps. Something to keep an eye on. Such a trivial component could put you in a world of hurt if it happened in the wrong place at the wrong time.

My top radiator clamp wasn't even ATTACHED when I brought mine home from the dealer How would a brand new FORD look stuck on the side of the road with steam pouring out of it and 25 miles on the odometer. The Chbby guys would have got a laugh over that one...but the hose held!
[updated:LAST EDITED ON 09-Mar-02 AT 07:13 AM (EST)]My truck made a whistleing noise similar to what you are describing on a very cold morning in Jan. it was about 5 degrees out. I thought it was a vacume leak it hasen't made it since although it wasn't a very cold winter here in Massachusetts this year.
