Normally I drive on the faster dusty roads with A/C on, but due to the VC not working I didn't want to push my luck.
So to be sure engine stayed cool(er) I ran without A/C. hence dusty .. everything!
My last trip out Cobar/Broken Hill about 12+ months ago(I think), when I ran on a few dirt roads(80k/h or so) out Menindee/Pooncarie way, no problems .. I put up with the high 90's engine temp. I vaguely remember engine temp topped out in the high 90's down that way.
So I close windows, set recirc, A/C on .. no dust.
Drive across from Cobar to Broken Hill, there was one kind'a steepish hill just approaching BH, and engine temp peaked at 117! with A/C on. Only a very short time(30 sec or so).. backed off, A/C off and cooled down.
But that was just the climb section, for the 200 odd klms on the flat, it sat in the 90's. Ambient was about 43°C that day.
I didn't run with the A/C on all the way, just every now and then, mainly to see how hot the Tdi would run.
With the A/C on, and the temp sitting at about mid to high 90's, I'd turn off the A/C run for a good half hour and temp would eventually settle back into the low to mid 80's.
And yep! .. A/C electric fans both come on with A/C on .. and I assume they both push air in the right direction! (haven't actually checked tho).
