Can I remove my auxilliary belt to help identify a noise?

<< < (2/2)

Tel:
Power steering and aircon by the sounds of it spin each pulley by hand and see if you can hear one making a noise of feel one with movement you also have a tensioner pulley below the water pump 

Nick4X4:
try changing the belt  ;)
if you look at your one i bet you got tiny little stones in the belt :)

Trax99:
Could be the belt tensioner bearing - get replacements on ebay.
or like me it could be the alternator back bearing - squeals like a squeally thing. :'(

5 pulleys, you havn't said but I'm thinking this is a TDi, or am I wrong?

Squeeking is as siad often caused by the tensioner pulley, they are often a tiny bit out of line and some folks true them up by jamming a penny undeer one side of the tesnioner block as they fit it.

TDI has a separate belt for the air conn, if we are talking V8 then the belt set-up is differnet for with and without airconn, without the tensioner runs on the multi-vee side, is plastic and doesn't cause squeeks, the belt is noticably shorter.

Sorry - I'm expecting people to read my mind again - it's a Tdi.

The tensioner squeaks from cold and then stops when warm. The mystery whine starts about one minute after starting and then won't go away.

I'm going to buy a belt/bearing but I'm reasonably sure it's not those which are causing the noise.
