no visable leaks, I will check the carpet, do these cars blow head gaskets?

500 miles - since what?
a 2000 is ready for a heater core - check both sides.
If you just replaced fluid, hoses, or radiator you may just be having some trapped air working it's way out.

You may have a leak at the head gasket. But check under the overflow reservoir where the bottom hose connects to the tank. Hopefully you just have a bad rubber hose.
