Ah yes... had that problem. My fan belt broke and I had trouble renewing it. When I did get it (it wasn't the same size as that quoted in the manual), I bought a spare. The next time the fan belt broke, I asked the Automobile Association to come and repair it (we were out on the road) and they insisted on bringing the quoted fan belt with them. I told them it wouldn't fit but still they tried.... After about 20 minutes I suggested they try my spare, which fitted perfectly. Not only did they try to charge me for their fanbelt (which I'd told them wouldn't fit) but they tried to charge me for the one I supplied!!
