Water pump engine mount 440

Yup its overheating. I thought I had it all figured out because it would just run a 195 for awhile then it started getting hot again and overheating. Sometimes the temp will slowly creep up and up and sometimes it doesnt even slow down. I've changed the thermostat i've changed the radiator cap, purged all the air and it still does it. It will over heat driving or idling. I just don't know what else there is without tearing it apart!
