Any pics?

For those of you making comments that your old MK or commodore had colder A/C...yes it would have as older cars used R12(ozone unfriendly) refrig gas that could regularly spit out 3°C. The ML & MN use R134a which is kinder to the environment but is far less efficient as it wont get as cold and runs at higher pressures for the same temp when compared to R12.
Having said that, I find my ML petrol triton doesnt have very good A/C whilst at slower speeds (ie in traffic or at idle) this is because the compressor isnt revving much(low rpm) and also the amount of air flow going through the condensor at front is also minimal until the viscous fan cuts in. To get the coldest air out of your triton I recommend: higher driving revs (2000rpm+), driving at speed(60kmh+), recirc on, low fan speed (1 or 2 max). Driving like this on a warm/hot day for 10 - 15 mins should still yield around 10°C or better depending on outside temp.
For those of you putting extra insulation on the low side(cold) pipes that will definitely help, if your insulation is melting, try aluminium/thermal tape wrap over it or also butyl or black cork tape(gooey sticky insulating tape) to keep the temps down.
The front electric thermo fan would definitely help but I have seen some people install these with the blades facing the wrong way. Depending on their design(curved or straight blades), it may be a better air pusher than puller and some dont like being turned the wrong direction depending on polarity or direction flow) Check install instructions carefully.
Finally, as previously suggested keep your condensor/radiator clean by reverse washing water or compressed air to clear any debris.
Hope this helps,
Cheers,
Ken

R134A has been around a long time, at least 10 years, when fitting air con to MK tritons, CE lancers etc we filled them with R134A, as far as commodores go you'd have to go back past VR (1993) or even further to find one with an R12 system, so it's still a fair comparison to say that older cars with r134a have had better air conditioners than new tritons

It was and still is an ozone depleting gas. R22 will go the same way eventually and there is plenty of not so old A/C units and other stuff using it (not in cars).
