When driving on the expressway Temp is about 190 to 200 Temp in stop n go traffic is about 205 to 210 90 degree day. I have 180 TStat 185 fan switch sensors fans work fine and are new. 3 Row radiator Engine runs strong. Really only thing left to change is to Rebuild the t body. Maybe a bad head gasket? No leaks of any kind. Kind of at a loss
