Welcome to the forum. It sounds like you could have an external head gasket leak, leaking coolant.

Sounds like that to me. I just changed the head and gasket on my 95, and it took us 14 hours over 2 days to get it done. It might possibly be a crack in the head as well, the older 2.3's are well known for cracking heads.
