340 Overheat / Radiator Geyser

UPDATE...I have not had the time or motivation to look at the most recent replies. Why? because I was told on Thursday night that my squatter left the property to stay with a friend and the Sheriff Deputies told him he can't come back. I closed on the property Friday morning. When I went there the next morning HE WAS STILL THERE and he told me never left on Thursday and had been there the whole time. This is just a very small part of this whole story, but the most important one. Civil suit and complaint to the TN real-Estate Committee are both started.
