My 04 does that, never could figure out what it was, sounded like a turbo whistle LOL, one mechanic told me he thought it could have been a small leak in the manifold that would go away when it got warm, just dont want it wo be something that I have to throw a pile of money at
My 04' 5.4 did it whenever it was below about 10. I live in Northern VT, and sometimes maybe once a year it will dip down to about -45 at night, it will start that cold, but its ear deafening the sound.
My 04 does that when it gets below zero out as well. Most vehicles make strange noises when it's that cold though, so I've never looked into it or thought it to be a problem.
@02LM7 Yeah it is, alternator bearings and cold, didn't get along. It hasn't done it since 2009. Past couple winters have been fine, even on the -17 day we had in January 2011.
@sstroh08 There are alot of engine differences between the 2v 5.4L and 3v 5.4L, '04+ 3v 5.4Ls have been the majority of whistle reports due to tensioner pullies.
@DarrenWS6 ive worked on both the only major difference is the heads obviously, the pcm is a little different and they have an electric rheostat throttle controls instead of the mechanical cable ones theres a few other very minor differences but i cant remember anymore of em lol, the belt and pullys are the same on these trucks, must have just been a bad set of bearings or something in 2004 idk
I don't know if you still have this problem? I had the exact same thing as you (check my video) It was my alternator which needed to be changed and the whistle sound never came back. I live in Canada and get around -30 at some points in the winter. It was embarrassing starting it up!!
@bonesofsteel Thats cool. Funny thing is after taking this video it never did it again. Past two winters has been fine. it must have been ice in a pulley somewhere.
oh wow man lol just bring a hair dryer along and a dc conveter so next time you can melt that crap lol jk, im sure they make a pulley that will fix that right?
@ThugSniperx Cause I didn't have a block heater. It gets cold in winter here. Cause I splashed through a slush spot before I parked. Never gonna happen again since I have a paved driveway now.
my 06 has a wistle when its cold and under load like driving down the highway. its at around 2500-3500 RPM. and it does it at idol too when its cold out. ive been to multiple dealerships and they all say its in the intake; one of the oxygen sensors, or the EGR valve
@amintha91 Some people on F150online have reported it to be a cold belt, a little ice causing a whistle, some with alot of demand from their battery needed to replace the alternator. In my case I think it was ice on the belt because I haven't heard it this winter.
I had the same exact noise. I changed the tensioner pulley and problem solved. With that said yours may be the idler pulley or the tensioner puller. Either way very easy to check.
dude i get the same wistle only when excelerateing when the temp is below 30 degrees and only when the engine is cold. and the wistle is much quicker then urs. u have any clue what causes it?
It's your rear alternator bearing. I had the exact same thing on my 04 F150. It only did it when it was really cold. I was worried my neighbors would yell at me because it was so loud!!! NEW ALTERNATOR! :)
well im up here in ny, mine doesnt wistle like the one in the video. well it does just not as loud. i have no clue what it does. but it only does it when its like 0 outside. it dosnt last long. i have a k&n fipk on mine so i dont know if its the filter
really. I noticed around my air filter tray there was some loose foam sealing around it. I'm thinking thats one of the causes because in those really cold mornings when it starts its at 1300rpm.
that doesn't sound so good... we had a 98 buick park ave that did that in cold weather like this with a 115k miles on it and it turned out that the lower pulley was broken and our clutch was fried
Mine does it too, but not that loud. Actually was louder when I first bought the truck in December. I've pretty much just resigned to live with it, it only does it for a minute or two and then it's gone. Doesn't seem to cause any other issues, so I'm just gonna see what happens.
yes, I always lea ve the head on Defrost/Overhead maxed out because I run it for 5 minutes before I drive. Dont like driving a cold truck, or riding in a cold interior.
I see, and wow, then why is it doing that?!, did you check with the dealer?, was it a recall?, or does it just not like the cold?, or it could be your belt pulleys seizing up in the cold?
Its just too cold I think, no recalls on my truck, nothings wrong with it, runs great as it always does, just doesn't like the very cold start ups, look at the top and someone mentioned to me about the heater being on
Fuck you. Nothing is wrong with my truck, its called cold belts dumb fuck, I have to deal with below zero temperatures in mid winter, so fuck off. I didn't need a 3/4 truck nor did I want a Chevrolet.
ight ight buddy no need to spaz!! my chevy starts every mornign in below zero weather TOO and guess wut it dont wistle !!! so u fuckk off , im just sayin iv had fords and just had bad luck maybe there were lemons , so sorry if i affended u im just a chevy guy , i apolagize

just throwin it out there but is your heat cranked? My old 89 kinda sounded like that with the heater cranked? probly not but maybe just an Idea...

I see, and wow, then why is it doing that?!, did you check with the dealer?, was it a recall?, or does it just not like the cold?, or it could be your belt pulleys seizing up in the cold?
