If it's coming from the housing, it is probably a cracked housing or bad gasket.
does the 2000 ZX3 have this plug?
what replacement parts should i have on-hand if i am going to attempt a fix?
I don't think it has the plug. but i could be mistaken.
New housing, gasket and thermostat (Hoses to, depending on how bad yours are degraded). Take the housing off and verify it is not cracked. Take care to check the gasket for any abnormalities.
That's how I would start.
