No, overflow would dribble down in front of the pass front tire area. But if you cant find a leak, and you arent regularly loosing fluid, I wouldnt worry about a leak. So we have identified ONE issue...the missing Air dam. That part is AS important on highway speeds as your cooling fan. Please dont think that part is cosmetic or just 'helps a little'....its a MAJOR part of your cooling system at highway speeds. Dont even respond to this post until you replace that part. (OK, Im kidding about not responding but Im trying to drive the point home.....)

Have you checked to make sure it isn't from the heater core?

ok, i took out my thermostat and is now running w.o it, i replaced the fan with another slim electric fan hooked it up to a fuse that comes on with the key, so shes keeping cool, i have the air dam but the previous owner, seems to have lost the bolts to it, so i cant install it

Well, you probably shouldnt replace the radiator. Seeing how you have replaced everything else, why would you want to go and do that????

Are you running an aftermarket sensor, where is it placed, have you adjusted your timing lately?

The radiator is only a year old its in almost new condition that's y I haven't replaced it. It seems to be just a factory radiator. And it seems to work fine. She runs alright on the highway at around 230 degrees just a little hot but at redlights or city driving it just over heats
