Is there a chance that it was damaged from the prior owner. I wonder if he was trying to fill the radiator via the overflow bottle. Regardless, since you have it out, replace the thermostat, and flush out the engine block and heater core. That way you will know the system is clean and there are no blockages as rasmataz recommended checking.
Let me know how things go for you or if you have other questions.
