Thanks guys, problem solved, Cliff at PartAgents supplied me a new pulley, he is a pleasure to deal with. My car only had 108K on the clock when it let go, tell tail sign was heavy steering and poor A/C cooling (condenser fan was U/S too)
I replaced both belts at the same time, got them from Repco, the local dealer did not have them in stock would you believe?
Man, what a job to replace the air con consenser fan assy though! The pulley was easy to C/O. Still I know a lot more about my X5 now.
