Guys this is driving me nuts! While driving something is squealing horribly. Only does it when Its running and I have the truck at a idle or at a stop light. As soon as I apply the gas pedal it goes away. I have already replaced the alt, tensioner, belt and Idler with no luck. How ever after I changed the tensioner it went away for a couple of days then started back up again!

Please help me out! 2002 3.0 with 92,000 on the clock

 

Search the forum for cam syncro. It can make a variety of noises.

 

why don't you try checking the belt tension, its possible that you didn't tighten the tensioner enough and it loosened, mine did that before and thats all it was, it would do it when i tuned and alittle bit when i idled, and now that its cold again its doing that again and the belt is a little loose

 

Same as what he said, but with the Idler. you should make sure everything is tight.

 

Could be the belt is a little too long as well. When I was doing the belt dance during my supercharger install. Just a 1/2" could be too long and it would squeal at start up and idle.

 

The belt could be to loose or to tight if u didnt get the right tenison on it. It will squeal and make sure u have everything tight that u replace

 

THIS!!! Check it soon!

 

more like NOW!!! that's around the mileage they go bad, and will take your oil pressure with it!!!!

 

check 2 make sure your crank pulley aint coming apart mine was doing that & lastnite the metal ring slid off the rubber & was almost into the crank sensor
