Recharge the system through the low-pressure port, which has a cap that sticks up next to the radiator, near the battery. Fig. 1

It is best to stay away from the high-pressure port completely because of the likelihood of injury if the refrigerant should erupt from that side of the system.
One end of the charging hose snaps over the low pressure port. The other end of the hose screws down tight on top of the refrigerant container. The thumb screw at the container is screwed in to pierce the container seal, and then backed off to allow the refrigerant or the esther oil out. If adding oil, the can is held upside down. If adding refrigerant, right side up. Fig. 3
