What should a 2001 BMW 740iL (Japan imported) in the UAE be fitted with to bear an average 47 Celsius?

BMW's "hot weather package" on my old 318ti included fully opened air inlets on the bumper (instead of partially closed), bigger battery (to run the electric cooling fan) and not much else.But common sense items I can think of to check would be radiator, a/c condenser, fans...
