I have the same noise. I am afraid it may be the Timing chain tensioner but its odd that its only upon startup in cold weather. I cant get it to last long enough to diagnose it at all
Wow, I'm so happy to hear that, well, maybe I should not say that, I'm not happy you have the same sound, I'm happy to know I'm not the only one, and/or I'm not hallucinating.I have the same noise.

I think you are hearing the cooling fan at start up. A lot of noises you hear are normal, and if your not sure what normal is go to a dealer and listen to several Frontiers at cold start up.Has anybody had issues with the tensioner on the serpentine belt or premature failure of a water pump?
In the morning with it being in the teen and twenties here when I start the truck up I'm getting a noise that seems to whine and howl. It's not the noise one gets when a V-belt slips, and it is clearly not a valve head or cylinder noise. It sounds to me more like a bearing is not happy about being spun at such a cold temp temp.
Of course after the truck runs a while the noise goes away. I have taken it into the dealer but they could not replicate the noise as the engine really needs to sit all night and get stone cold.
Any body have any thoughts about what it might be?
That is exactly what I'm talking about! I have listened and listened and I'm having a very difficult time trying to figure out exactly WHERE it is coming from. Bottom line, my brand new truck sounds like a piece of old used-up crap and it is a bit disheartening.Mine does it, its gotta be below 20 degrees or so...
When I start the truck, it quiet, then slowly that eeeeeeeeeeeeeeereerreeerr noise fades in and after a few minutes it disappears. It's not anything I can see or really pinpoint by looking under the hood while it makes that sound.

It's like a heat wave here, oh my, all the way up to 36 degrees this morning at 6:30.
I started the truck up as normal this morning, absolutely NO NOISE AT ALL.
What ever this thing is, it is absolutely cold temperature dependent, which means I really need to figure this out because my truck is only my WINTER daily driver, once warm weather hits I have a CRX-Si, an S2000, and a VFR and the Frontier will sit in the driveway. So if this noise is causing harm, my truck is going to be subjected to it for a good portion of its life; a thought that does not please me...
What exactly are you going to try? I assume spraying silicone on the tensioner?http://www.clubfrontier.org/forums/f8/weird-sound-54371/
Check this out. Sounds like it might be it. Ill let you guys know tomorrow when I try it
