radiater flush

I am trying to drain my radiater. I can not see or feel the drain spout. Is there something I need to remove so that I can see it or can I drain it by loosening the lower the lower hose? It is a 1999 with a 350.

Thanks in advance

Guessing you found it by now. On my '87 the drain cock is located on the lower right hand side of the radiator, on the rear of it. It's kind of hard to see because of the plastic shroud on the back of the radiator. I reach in through the fan blades to get to mine if I remember correctly. Of coarse that's with the engine off.
