Hmmm, I don't think you are going to do a good job of *changing* the
coolant this way.  you may be able to drain it by doing it hot (ouch!
warning, nice 220 degree water spilling all over!) but then the
thermostat might close, etc etc. (good for burping it though)

to *change* the coolant you gotta pull the thermostat.  It is a lot more
fun to do with a cool/cold engine.

And don't poison the kitty cat. (meant literally)
