overheating
Well I was just wondering if there’s any minor leaks’ coming from the radiator. But if there aren’t any leaks, check the expansion tank cap. This may not be the problem, but check and make sure the return hose to the expansion tank isn't clogged. Because it sounds like you have some kind of leak/restriction somewhere, maybe it’s so minor that you can't tell. And the leak may not be leaking out coolant but pressure from the system. The best way is to have it pressure tested.

Re: over heat
check your fan clutch or aux fan (but i dont belive you havean aux fan) runn car to opearting temp and stop fan you can use your hand but make sure you stop it before it starts to over heat. once stoped hold inplace with fingers flat on blade and wait you may want another person to monitor temp and make sure your not overheating the car if car is getting warm and the fan has not engaged(pulled away from your fingers with fource ) if this dosnt occure then your fan clutch is bad and will need to be replaced
