    Default 6.6L Noise/Squeal

    Approx. 45,000 miles
    at around 1,300 rpm ( lasts only approx 50 rpms )
    I get a squeal / squeak. It seems to be in the area of top rear/right side of engine.
    Any ideas would be greatly appreciated

    The idler/belt tension pulleys have produced these sorts of problems. Remove the belt, and check all of the belt-driven accessory bearings for smooth turning. The belt tensioner though is the likely suspect.

    Squeal / Screech Noise:

    This noise is noticable in Park accelerating thru 1300 rpm, and drive conditions. This is the only time the noise is noticable. I used a stetiscope around pulleys and all of them sound different.

    Has the belt gotten wet lately? When mine gets wet it squels. Just my 2 cents.

    It sounds like the noise is in the turbo area.
