Hi, guys.. Thanks for all of the help and suggestions. Actually it turned out to be the temp sensor. The brand new one ( UroParts ) was off by 7'C from the actual temp of the engine. We put the original back in, and temp stays at 85'C all the time regardless of the speed or outside temp. My next step would be to run it with AC on.. I will let you know what I find...

Thanks again to every one who tried to help..

Mark
