When I changed the DCCV and fixed a leak in the coolant mainfold, I disconnected the hoses that go to the intercooler to make it easier to work. Not much coolant came out and when you remove the bleed screw the coolant is mostly full with the engine off.
Hard to know if you really need to do it but its easy enough to assure that their is no air in the SC circuit. Basically, just remove the plug while the engine is running, the coolant will slowly riseup and start to leak then reinstall. I just did it to be sure after a standard coolant flush just to be sure.
Requires a pretty big allen wrench to get to it so I just used a bolt head that fits with two nuts tightly thread on it. Stick the head in the plug and use a normal wrench to loosen.

When I did my coolant exchange I simply drained the main radiator and then the the intercooler by removing the hose from the pump at the bottom. Then to fill it I used the hose at the top of the intercooler along with a funnel to fill that portion of the system. It will self bleed into the expansion tank simply by having the pump on via the ignition key.
I did this as the very last step because I was using the successive dilution of the cooling system method with distilled water in order to effect a mostly complete coolant exchange without getting at the block drains. I imagine that those are difficult to access? Once the main system had been flushed enough I drained it one last time and added the proper amount of pure coolant and then any water as needed based upon the system's capacity.
The intercooler got filled separately with a 50/50 mix.
I never had to touch the plug this way.

For those of us who need an excuse for a new tool, it is a 19mm wrench; about 17 bucks from McMaster -Carr:
