Those are such a pain! That's why I like the hose. 12 is the min drain possition. The max it 9 o'clock possition. This is out of the manual:
The draincock stem is closed in the horizontal position, pointing to 3:00 o’clock. Draining takes place through the cooling
module’s lower right side insulator.
Do Not Use pliers to open draincock. CAUTION: Do not pull outward on the draincock flange while opening. Damage to the draincock body and O-ring seal may occur
(1) To open the draincock to the minimum drain position, turn the draincock stem countercolockwise to the 12:00 o’clock position. For the maximum drain position, turn draincock stem counterclockwise 180 degrees to the 9:00 o’clock position.
(2) Remove coolant pressure bottle cap and open the bleed valve.
PS If I recall correctly, AFTER the valve is turned, it can be pulled out...then it really flows, but see caution above before you try anything like this.
