Note quite today, but over the past couple of days, it did a couple of thousand klms 
I'd love to say trouble free, but not entirely the case.
One slow leaking tyre put a slight dampener on the places I wanted to check out.
Other than this one tyre car was trouble free.
Still running without my fan cowl(at all!) and no issues with engine/coolant heating up.
Ambient was over 40° for a lot of the way too, and it got humid at some times too.
I recently used the CEM flush treatment stuff, flushed and re added the treatment again.
Now with A/C on and over 40° I'm no longer seeing over 100°C coolant temps.
Did get into the mid to high 90's, but once in the high 90's it came back down .. so that was good to see.
I generally don't run the A/C anyhow, except on dusty/gravel roads(windows up, A/C and recirc on) just to minimise dust on my gear.
The flat started just outside Cobar on the very easy, but large gibberish road to Mt Grenfell Historic are.
Could have changed it, but felt way too lazy, as I was on an easy drive .. so wanted to keep the annoyances to a minimum.
Thought that I could get it fixed in Wilcania, but couldn't find anyone to do it. So had to keep going to Broken Hill.
Was losing about 10psi every 50klms, so I just stopped for a breather every half hour-ish .. set the compressor to fill it to about 50psi and continued on till the next spot.
I have a TPMS to keep an eye on tyres, so it wasn't as dodgy as it sounds
While it appears to have been an annoyance, I generally stop at most spots anyhow .. just the annoyance of getting the compressor out and stuff.. no biggie.
The major annoyance was that I wanted to get up into the Paroo nature reserves and check out those places. (Didn't want to risk any more damage tho).
The number of feral goats is amazing.
Anyhow, with fan cowl still at home, cooling isn't the issue that many seem to think it would be having deviated from 'design specs'.
With A/C off on the 1000°C bitumen!!! coolant was running mainly at 85°, IR temp check of head showed 85° at most spots, a few near the back showed 88-90 .. Oil temp stayed mainly at about 70-ish.
With A/C on, at 80k/h I was seeing high 80°'s.. maybe 90°. At 95k/h it was hovering in the mid 90°s. Did see 100° on a few medium climbs, where EGT topped 700° tho .. so I still need to keep an eye on it.
One slight off road track tho, with engine at about 2K RPM, steep incline 1st(high) so a bit of a load on the engine, but not a massive load, coolant in the low 90's, EGT high 500's with A/C on.
I could have dropped into low range, but the track was short and 1st high was fine.
All in all tho, I think this CEM flush has helped massively .. so a rad clean/check replacement is next on the list of things to suspect, once I've done a few more flushes.
I'm thinking if it does in fact clean the scale in the engine, I want to do more flushes before I fix the rad .. don't want to flush engine clean and have it clog up a new rad.. clean engine first, then once that's as clean as it will get, then do rad.
As it is now, tho, a far cry from the 100° + temps I was seeing even as low as 80k/h on a hot day.
As to drive it home again!!!! .. the temp gauge needle didn't budge a micron in all this time between 80° to the 100° I momentarily saw on the coolant gauge.
Oh!... and A/C works brilliantly even in 40°C ambients.

All these discos are giving me a heart attack!
