I have the reverse problem. My 02 runs a 190* I think and in the winter it throws a lot of heat in the cab. But in the summer while towing it runs hot. 195* and when you step into it on a hill it will climb over 210*. If your not paying attention I have seen it in the red of the stock gauge! I run a edge attitude and tow on level 3 because 4 and 5 can't pull hills with this heat issue.
