Help, coolant leak, Heater Core?

Ok, i have a 90 Z-24 3.1 lit. Driving home my low coolant light came on, shortly after that i smelled coolant and the temp gauge went up.
When i turned the engine off a mist came out of the vents. When the car cooled i checked the coolant level, Empty! I put more fluid in to check for the leak, it was leaking around the center bottom of the firewall. When i looked i could see an Elbow comming out of the firewall with the fluid comming out of it.

Should there be a house connected to this or is this a drain?
I've attaced a pic of the mystery elbow/hose? it was taken from the top of the motor.

thanks
Greg

There is no coolant drain that I know of on the firewall of any cavalier!

There should be 2 hoses that go into your heater core, they are side by side. If there is only one on yours, then you lost a hose. It looks to me like you lost a hose.

sweet, thanks guys , i just had my heater core blow too exact same symptoms on my 89 z24, i was not quite sure if i was just missing a hose on the engine side of the firewall cause it was draining out there also..
but i was 99% sure when the mist fogged up my windows, and my floor board was soaked..

thanks , i am more confident on how easy this will be to fix now..
perhaps ill take some pics on the repair... and post up.
