Cold Start Question

Dmax3133 · 11-06-2009, 08:12 PM

I recently put the new edge evolution on my truck, had it on level 1 for a few days then i put it on level three for a trip around the block got on it pretty hard and ever since have had a short squeal/chirp noise on cold start ups. It makes the noise when the truck is cold or hasnt been started for a few hours and doesnt do it right at start up, it does it a second or two later when the turbo cycles through. The noise will only last a second then it goes away.

Ive tried to listen to where its coming from and its almost impossible. Any ideas on where the noise could be coming from?

Does it sound like its coming from the serpentine belt? I know the tensioner pulls go bad which would squeal or squeak.

Well ive had someone start the truck while i was under the hood and it doesnt really sound like its coming from the belt. I have also laid under the truck and had someone start it and it sounds louder underneath the truck.

I just went thru and changed both of my idler pulleys and my tensioner. When it was colder out or raining my belt would make constant noise but but when it was warm out it wouldnt make a peep. It was louder whenever I started it up and the engine was stone cold, hope this helps a little.
