Could be a bad tensioner, belt, pulley, etc. Have you had anything inspected?

Then maybe just the temperature around that time of day exposes a weak component. Best to inspect the belt and such.

Whatever you do, don't use any of the old treatments for fan belts (soap, any lubricating spray, etc.). The new serpentine belts HATE being lubed, and if you are getting a belt squeel at any time, it is more related to a pulley being out of line, a tensioner being weak or one of those prematurely wearing the belt itself.
The noon thing is just related to the belt being warmer and for some reason slipping enough to squeel.

I would definitely get the pulleys inspected and check the belt.

So I just now poped the hood and listend to the sound it sounds like it is not coming from a belt it sounds more like it's coming from a driver side injector or back of the motor on that side

Have someone give the car gas while you listen under the hood. See if you can further pinpoint it or if the sound changes.

Possibly a leak somewhere then. Could be exhaust or vacuum. Exhaust might be more of a ticking though. The pressure or load increase can make it apparent or go away. Double check/trace all hoses and make sure everything is connected and tight.

Edit - Can someone confirm if the timing chains and pulleys are in the back of the engine or front?

Trying to look at this diagram but it doesn't specify - http://www.fixya.com/cars/t12736493-...7_timing_chain

I think it might be a timing pulley >.> the more i listen to it because it is coming from with in the motor i know that for a fact now. but it does not seem to be affecting performance... In fact since this started happening about 2 months now or so. I have been getting really good 0-60 times better than before it started to happen. <.<

That would suck if it was a pulley. I had one go out on my 3000GT while I was driving down the road. Luckily, the engine came out fine in the end and once I got the timing issue squared away, the car was good to drive again.

There's a thread on this somewhere here in the v6 section. A lot of people's cars do this on start-up, including mine. I think it my have been titled something like "squealing" or "screeching."

Here's one of the threads. I think there's another thread out there though.

Belt sound?

Have had the exact same problem since ~2k miles. Told the dealer about it and they explained that they couldn't help me if it wasn't reproduced with them. For me, it happens mostly in the morning when the humidity is slightly high. It goes away after 30 seconds and i have read a lot of other owners having the same problem so I'm not too worried about it.

my squelching happens at like 6 to 700 rpms only. and it only does it at certain temperatures. it's really weird and annoying, yet goes away when the car warms up. saw a lot of other people had the issue too. I've got a video of mine on YouTube here https://youtu.be/3e9BlVR7L8Q

Yup, does it to mine too. From what I've seen with other v6 owners, it seems like humidity plays a factor, though that's just a theory. It does seem to be a "normal" problem that resolves itself within 30 seconds to a minute. I drive in a parking garage at my job so I can hear it bounce off the walls pretty clearly when I leave, but still have no idea what causes it.
