Clois Harlan,
Thanks for the swift reply. I am running a serpintine belt but the pulley set up was installed by the previous owner and I wanted to check that counter clockwise was correct. I suspect as you suggest it might be air in the systen so I will try removing the temp sender. It's late now in the middle east so I'll try your suggestion tomorrow morning. I'll let you know the result.

Thanks,

Ian
