Managed to do the job between showers this morning, It definatly a right hand thread on the fan. Thanks for that I'm used to fords with a left hand threads.
Only problem was securing the crank pulley to undo the bolt, In the end I used a piece of 3 x 2 about a foot long jacked up under the pulley while I broke the bolt.
The tensioner and idler pulley under the PS pump, Bearings don't seem very clever can the bearings be changed or is a case of replacing the whole units.
Thanks
Steve
