radiator fluid leaking help

5 speed

Going down the highway, car started over heating real bad.  I pulled it over and there was radiator fluid pouring out the bottom of the car.  Looking around to find where it was coming from, i found the leak, but i do not understand what it is.

It is coming out of the firewall out of a fitting in an elbow shape that is pointing straight down.  I looked around thinking a hose or something popped off, but there is nothing around.  When i put new fluid in, it just drains out of there like a faucet got turned on.

The only thing i could think of that is near there is the heater core, but i dont understand why there would be an elbow just draining all my fluid.

any help?

That's a typical heater core failure.  The hose cracks on the core and all the coolant pours out and runs through that drain tube.
