First, I want to thank you for your patiences. If I was there, you could show me in two seconds. However, when doing the via the internet, it takes longer.
As far as the problem, I want you to check the radiator hoses to see if any of them are pinching shut. Check when the engine is both running (hot) and first shut off (hot). Also, let me know if you replaced the waterpump. The radiator is a concern to me, but if the engine only overheats when it gets low, then the radiator (if not leaking) is doing its job. I would hate to see you get a new one only to have the same problem. Maybe try to have it boiled / rodded out. I know where I live, there is a shop that does all my radiator repair work. They charge 40.00 to boil it, rod it out, repair any leaks, and repaint it. They look and work like new when I get them back. I only ever had one problem over the past 30 years I delt with them and they took care of it.
It's just an option for you.
Let me know.
