Ok is the coolant drain the one closer to the pass side??Behind that bracket that holds up a small wire harness coated in green locktight i guess??
From what you are describing that sounds right because I remember it is just above and behind a bracket holding an electrical connector. It is on the firewall side, closer to the passenger wheel and up higher than I would have suspected. It is also a brass plug which stands out if you can get a flashlight on it.
