Its pretty simple once you figure out how the bottle works. The bottle has a small top that you unscrew (leave the blue sleeve intact!). This reveals a smaller diameter nipple. I screwed it onto the fill nipple on the passenger side of the car (easiest to reach). When you screw the bottle onto the fill nipple, nothing happens.... You must push down on the bottle itself. That releases the fluid. It went in without spilling a drop. A master piece of design work for this nasty product!
