Hi Chuck,

Thank you very much for your reply. I understand that the article was written quite some time ago, but I appreciate your time to reply. I will definitely look at the temperature swing in warmer weather between highway and idle speeds and if they are too severe, I will look at the 180 degree thermostat. It was interesting to hear from a local club member regarding the Tiger coling system. The person was talking to a very reputable radiator shop who believe that they can cure the cooling issues by a latest technology radiator and some pump modifications. If you are interested, I could find out some more information regarding the mods.

Regards, Robin.
