Hi:
If you overfilled the coolant, yes it will come out of the overflow. If the level is staying above the add mark and not dropping, you should be fine. If you find that it continues leaking, let me know and I'll try to help you figure out where it's coming from. Just keep an eye on the temp gauge for awhile to make sure everything is ok.
