Get a 3/8 hex extension and loosen but DO NOT remove the HX vent plug through the front grille upper left facing the car. Be sure the Extension fits well or you will strip the head. Now with the vent open also open your fill plug at SC, that should allow a gravity bleed. Close the HX vent and refill, repeat until full.

Or as mentioned get a reservoir. I have the MAC tool vacuum I paid 230 never used it as I have a lift so I just remove the speed clip on the lower pump HX line open my reservoir and SC fill plug and drain the whole thing into a bucket. Refill through reservoir until it begins to fill, then fill remainder through SC fill plug unit reservoir is full, run motor with reservoir open add fluid as needed.
