Jason I know on the PA there is enough room to at least remove the PS reservoir cap.
If you dont want burns, only try to remove the cap when car is cold only.
If on the imp you can not get the cap off because of lack of room I dont know what to recommend.
I use a veterinary syringe ( guess it works on cows too) with a 14" long rubber hose attached to syringe to remove the old PS fluid. I found the fluid to be extremely dirty especially from the bottom of the pump. I filled with fresh PS fluid, started the car for a minute rotating the wheels back and forth and then suctioned out the fluid again.
The fluid came much cleaner on the 2nd suctioning and I refilled with lubegard PS fluid.
The pump immediately became very quiet as I expect the LubeGard synthetic removed most of the friction and it remains clean now at 20k miles since it was changed out.
