I tried to take the plug out of the Hornet (see my sig). I tried a breaker bar with a 6' snipe, and I also hammered for about 30 seconds with a 3/4" impact wrench we have in our shop. Nothing was getting the plug loose.

 

Rather than have the threads come out with the plug, I just gave up. I bought an inline block heater and put it inline with my heater core hoses. It's an 800W heater, which should be good enough. If it's not enough, though, we have a 1500W heater for a tractor laying around as well. That would be overkill, though.

 

Inline block heater is my vote.

Air chisel it. Put a notch into the flat part on one edge by pushing straight toward the plug, then when a good notch is dented in push the gun left a bit against the edge of the notch to loosen it. from there the 1/2" gun should remove it.
