You're welcome! My advice: Check the bleeder screw on the t-stat housing, make sure it's not stuck shut. New ones are available from Rock Auto or your local parts store: Dorman Part # 902112 (pk of 2)

To drain the radiator, just take off the lower radiator hose. Don't bother with the drain valve, they usually break anyway.

To refill the cooling system, I always remove the t-stat housing and t-stat, and pour the coolant/distilled water mix into the lower intake manifold. That way, it refills the radiator at the same time, and helps keep air pockets out of the cooling system.

Hopefully your radiator is ok, but at this point it wouldn't hurt to replace it if you have the cash. You'll need to make that call once it's out.
