If your going to hang a radiator that sits over the cockpit do this so it won't spray you even incase of a boil over, then you can leave it up in the air..
both inlet and outlet have a section of pipe that makes all the hose connections to a point that would blow water down and away from passengers.
Also I wish I had taken a picture. If your hanging upside down in the car..lol which i was the maiden day. ( locktight on that rack-pinion set screw ok )
The head breather if mounted on top the head will allow oil to run out and down your neck...which could burn..
