If its running at 205, that's normal and there's nothing to worry about. if its going hotter though you need to fix it. After all that cooling system work you've likely got air trapped in the cooling system. it can be tricky getting it out. if using the bleeder valve won't do it you may need to drain and refill again. Sometimes doing it with the nose pointed uphill helps. Sometimes you need a shop with the proper vacuum equipment to do it for you. And of course, make sure the cooling system is full. Its easy to overlook the obvious sometimes.
