Total coolant loss

[Jus]

Hey guys!
I have a major problem here, well at least i think i do. I was making a liquor run last night and all of a sudden i have this huge cloud of white smoke behind me and the whole car smelt like coolant. I limped the car back to the college parking lot (it was less then a 1/4 mile) lifted the hood and of course everything was wet. checked the hoses for cracks nothing. I put some coolant in it and it poured out all over the ground.

So my question is what would brake or crack or fall out of the bottom or side of the engine that would cause me to lose all my coolant?
I'm thinking frost plug but is there anything else?

yeah could be frost plug/knock sensor, or your rad is cracked..did you run over anything?

I found it. The block heater fell out. I'm going to order a new one in the morning. What a PITA to get at.

looks like who ever installed it over tightened it. the brass piece on the back broke. good thing it stayed on the screw
