v8 Serpentine Belt Noise."wuw wuw wuw wuw"

[Robgw]

Excuse the demonstration again... but on tick over I have a

"wuw wuw wuw wuw wuw wuw wuw" noise quite loud too! coming from the front of the engine. If i increase the rev's from idle it goes away but again at lights etc if comes back.

Seems to be coming from the Tensioner. Should I replace the pulley wheel or just the bearing? How can I be sure it's just that Pulley?

Alternator and AC are quiet. Viscous Fan OK too..

Interesting Iv'e just been playing in that area on my td5, personally I would replace the tensioner as I have found in mine, that after replacing a lot of other ancillary parts, I have some slipage of the belt and after removing the fan cover I can see a pulsing of the tensioner at idle. Bought one on ebay for $125 in Aussie but could have got one from UK for less than half that, just didn't want to wait--best of luck:D
