Well when i start my truck"98 jimmy 4dr 4x4" in the morning i have a squeak coming from under the hood, Goes away in about 15 seconds usually then it will be gone all day. Now today it went on for about 5 min then gone, But has come back almost every time i start up my truck. In the video i caught the noise pretty good, There is some other noise caused by the fan, But you can hear it pretty good. Around 1:30 the noise stops and is gone. Any idea's let me know, Thanks ahead of time.

take your belt off and spin each pulley by hand, the pully that makes the squeek when spun by hand is the cause of the noise. im guessing the idler pulley. while your in there, it wouldnt hurt to replace the belt.

 

^ I second that

 

^^^^xx2 for sure something to do with the belt lol

 

Well i got around to checking out what the problem was today since i was off work, Sure enough it was the belt. I was thinking the squeak was gonna be from the p/s pump, The belt was a dayco only had about 3000 miles on it, Changed it after i put in the new motor so i didnt think it was bad already, But I replaced it with a Gates kevlar belt and the noise is gone. Thanks for the help and Dont buy a dayco belt.
