Welcome to 2CarPros.
Correct me if I'm wrong, but if you remove the spark plugs, coolant is coming from the engine/spark plug hole? If that is the case, either you have a crack in the head or engine block, or a blown head gasket. When running, are you seeing excessive white smoke from the exhaust?
Take a look through this link and let me know what you find.
