mine will run 180-195 all day long in traffic bumper to bumper maybe it'll hit 195 on a 100 degree day. also water wetter does seem to help a little. and i only use the electric fan when i turn it off......... i do belive there is another type of water wetter stlye stuff on the market its the color of antifreeze waater wetter is pinkish red............ if all else fails take out the thermostat and use a thick washer constant flow with some restiction
