My civic is having the exact same problem...I am going to go ahead and replace the thermostat, but don't know where to go from there. I was supposed to take a 600 mile trip this weekend, then this decided to put a cherry on the cake of my day. It could be on eof the sensors in the radiator maybe...I guess I'll find out Monday.

Feel your rad hoses and if the lower one is cold then its your thermostat. If there both warm then the thermostat has openned. Are you sure you have no leaks, check around the water pump. Did you bleed your coolant of air? If your fan is not working, then it should be overheating in traffic not on the freeway. My fan never used to come on and i was fine at high speeds, the temp guage would move up a little only when i was stuck in traffic.

the temp never goes up when im on the freeway it only goes up if im on the freeway for a half an hour or more then soon as i get off in traffic i know im not leaking any water and i just shanged the thermostat its been a while though ill pull it out and throw it in boiling water see if its still good but it still over heated right after i changed it before it never over heats only when i get on the freeway for a bit then get off thanks for the info
