Thanks guys, I really do appreciate your comments. - I fixed it. It turns out that it was not overheating at all. I replaced the temperature sensor and that did it. I guessed at that. If the guage was reading 240, then dropped to 220, than ran back up to 240 and stayed there then the new thermostat had to have opened. It opens at 195. so... It is now reading 200 or under consistently.
