i thought i heard this yesterday when i left work but i was tired and said its in my head, THEN i go to leave right now and sure enough its a real sound
you can hear it very well through the front grill and then if you turn the volume up you can hear a ticking sound ever half a second or so, it also speeds up when i was pulling on the throttle cable. And after the truck fully warms up it goes away.......

 

im having a horrible time with Comcast internet right now, Tinypic and photobucket keeps freezing half way through my upload and i cant just use my iPhone since the app doesnt allow you to uplaod video and pictures

 

Once you get the video up we will have a better idea, Possible its one of the accessory's, you might have to take off the belt and see if it still does it..

 

Something is wrong with this crap comcast..... I'm using my phone to answer you's cuz the internet at my house isn't working. My video will show you how loud it is, at first I'm outside standing in front of my truck and you hear TICK TICK TICK

Well both tinypic and photo bucket froze again, I'll have to wait until tomorrow morning when all the kids are back in school, I guess comcast can't keep up LOL

Its really hard to tell in the vid but it sounds like a belt chirp to me..

 

yeah i would take the belt off and fire it up and listen again... could be a pulley, or the belt. i would try that.

 

are you talking about the slow click click click noise or the background engine noise that sounds like a diesel? that's how my engine sounds. are you having performance problems?>

 

sounds like a idler pully to me.

 

In the beginning of the video when I'm in front of the truck with the camera looking at the grill you can clearly hear a metal sounding TICK TICK TICK that's steady ever 1/2 second or so. I know when I open the hood it's harder to hear cuz of the fan pushing air all over but you can still hear that TUCK TICK TICK and when I pull the throttle cable it moves faster with the motor.

I put a brand new OEM belt on this August, and the idler pulley is the small 2" one that sits right above the belt tensioner that doesn't move or anything correct?
And tomorrow I'll take the belt off and fire it up what if the TICK goes away? Do I just put a new idler pulley and maybe a new tensioner on also? How do you figure out if the idler pulley is bad if all it is is a sealed bearing?

Use a spray gun. Spray only one of the pulley's and see if that changes it. That should help you to zero in on which one.

Just a few squirts.

 

If the noise goes away after you take off the belt, you can spin each pulley and tell if one is on its way out..
