I have a 6V92 as you know Todd, so my experience may, or may not help. On the flat my 6V92 runs about 185-190, and when we climb a long grade it will get just over 200....that has been the norm for the 7 years we have owned the coach. I do clean my radiator every few months, or when I see the temps begin to run 4-5 degrees hotter than normal. I was told not to use Simple Green as it is not friendly to aluminum, but I do use a citrus based degreaser (can't think of its name right now) when I don't have access to a steam cleaner. The steam cleaning gets the best results.
