Radiator drain petcock
How do I get the drain plug/petcock out to drain the radiator? I want to do a coolant flush, but I can't figure out how to get the plug out of the radiator. It's a weird, white plastic plug with no tabs or ears to grab onto in order to twist it out.
What I was planning on doing was running a flush chem like prestone, then hooking up a flush adapter to the heater hose with the tstat out and run it with the water running.

If it opens, a 1/4" ratchet head will fit inside and turn it. Still a pain to open and it takes FOREVER to drain... The Delphi replacement radiator I bought doesn't even have a drain...
I would say just pull the lower radiator hose
