Nicole.03.Civic

I'm not sure if this is the right place to post this...
Anyways, I have a 2003 Honda Civic. I was recently having some overheating issues. I had the thermostat changed and that did not work. I then had the radiator changed as the mechanic said it was clogged. There were no overheating issues after that for about a half of a week. I took my car from Phoenix to Flagstaff, which is about 150 miles. Once I got there I sat with the car idling and turned on my heat. It blew ICE COLD air and once I started driving again the heater remained blowing cold air, but the temperature gauge went completely hot. I checked the fluids this morning and there wasn't any room to put coolant in the radiator itself, but the overflow tank was completely empty.

id check that rad again crap could have flowed down from your lines and plugged it again.

Check for a blown head gasket as these engines are notorious for it.
