hi, welcome to our site. There are quite a few reasons for overheating; low coolant level to begin with, old radiator, bad cap that doesn't hold pressure, are a few that come to mind. Have your cap checked, flush the system and refill. Those are two things that don't cost much and could solve your problem. The second problem could be a leaky cylinder. Take off the drum and look at the backing plate, is the stain from the cylinder down? If so, that's your answer.
