Hi, sorry I cannot help with your quest for knowledge but I would question whether you need to fit one, unless you are in Australia or somewhere equally as hot. I've taken my P3 up some pretty serious climbs and long motorway trips in very hot weather and never felt the need for more cooling. You might just need to get your radiator re-cored. Best of luck whichever way you go.
