I read through the posts again and was trying to think a bit more about your problem. If your just getting hot and not really overheating by that much and your pushing more coolant than you should back to the resevoir to the point where you are loosing it then it would make sense that only a bad radiator cap would cause that, also the cap might be fine but the inner surface of the radiator where the cap pushes against might be messed up somehow.
One of the things I did for testing which might help you is pressure testing your system another way. Use a bicycle pump connected to a schrader valve and some pipe fittings including a T and a pressure gauge then attach this to the heater hose. That way you can watch the pressure of the system including the radiator cap. If when you pressurize the system you see your coolant in the reservoir start increasing before you hit the cap rating of 16psi then you would have your answer and know that the rad cap or sealing surface is the culprit.
I highly recommend not just replacing things unless you have a good idea that that's the problem. I created lots of problems and aggravation for myself by not following this advice.
