Question: radiator drain plug

Just swapping my thermo today and wanting to replace the coolant. I can’t figure out how that drain plug comes out. If it screws out, the wings on the nut hit my crossbar so that’s not going to work w/o something else happening. Does it pull out?
ALso, anyone use one of those coolant flush kits? YOu know the ones where you splice a t connector into your heater line, connect a water hose and flush it out while its running?
Just curious, I’ve done this with good results on american vehicles but wanted to know where to splice into on the Teg.

thanks,
js

hmm its supposed to screwout… maybe your Xmember might have been bent in that area? and yah the coolnat flush works the ame for all cars. which reminds me… i need to do that
