Thanks anthonyb,
I had already been thriugh most of those posts and replies, and found some useful information, but as I was trying to get the 8mm allen into the fan pulley I noticed that the ribbed part of the belt had a cut right the way across it and am going to order that and the service manual cd before I go on.

Thanks again, and happy motoring.

Cheers,

94teener
