Unfortunately I have a funeral. Also the car is in to have the fuel tank dropped and hopefully the leak fixed.

I'm sure there is going to be an opportunity in our near future.

I just want to say, I cannot recall Brisbane ever having such a textbook copy of what it's like in Birdsville in October. Dry and hot. It would have been ideal for testing the AC and car cooling.

Still didnt beat 1957s record

And when did 38.7c become stupid hot? RH was down below 50% - would have felt like a nice day

So I have the car back again. Drove home and would like to confirm I'm convinced that the clutch fan is working more often.. as soon as the car goes over 90 it starts.. so then it's back below 90. I don't expect I'll see the 105 I saw on the last trip.

The AC meanwhile.. was working ok (6-7 vent temps moving, 8-10 ish stationary) today but wasn't that hot. The mechanic suspects it could be the chinese compressor I just had fitted.

Next wednesday I'm taking it to another AC mechanic purely for an evaluation.

So the update is the car went to another AC person yesterday. "European specialist". Good reviews.

They looked at the car. He said the system is operating perfectly. All the pressures etc are perfect. It's just lacks cooling capacity.

On the drive home it was sitting at about 7.5 and then every lights it would start creeping up pretty quickly.. typically it would get to 10 or more at a set of lights. If you let it sit idling it hits 13. The fan was running when I looked when idling at 13 degrees.

He suggested the new condenser is probably as good a place to start. It's a known weak point of the system. Massive cost, but I'm not sure what else can be done.

I just want to record this for my future reference.

Trip to pick up camper. Highway and light urban. Middle fan.

Morning. 7.5 deg to 9 Deg.

Afternoon (hot 31, 32). 9.5-11 Deg. Slower speeds- higher temp.

I tried high fan but then the temps went up to 13.

I bit the bullet. Twin fan parallel flow condenser on the way from the UK. The actually claim it's got enough capacity to run their second air conditioning head that they make that replaces the centre console box. Apparently the factory compressor and this condenser can run both the front AC and this one. Interesting Idea though. 3700 pounds if you're asking for the Box.

I suspect that IS the answer but we will see with just the condenser.

The weather forecast in Brisbane is 34 tomorrow, and then a couple of 36's before dropping to 30 and then heading back up. Another crazy hot spring week.

I do think trying to get the AC working is super important if you want to run these cars in this heat.
