Thread: Driving in the heat

We did the same route to Fraser over Xmas holidays. Hot as well. My 90 performed awesomely but being on the 35s and doing 110-120 all the way my fuel consumption wasnt great. Got 350km to a tank. I wish 90s came with larger tanks

I haven't done this trip for quite a few years now , and was surprised by the growth in B doubles . It was very hot , looked like parts of the road were melting . We had the air running all the time . My fuel consumption was about 14.5 to 16 lts per 100km . I'm thinking about cruse control , the old right foot got very hot . The 110 didn't miss a beat very pleased with it . I don't envy truck drivers that do this for a living . They have my admiration !!.. Jim

What speed were you doing? It gets very hot in the cab if we do over 100km hr in either the 90 or the 110 when towing. There is a reason just can't remember why.

Out on the open Hwy sat on 110 often drifted up to 120 . I found it hard to sit at the speed limit That was NSW where the speed limit is 110 km . Vic and Queensland Max is 100 km . I suppose we all suffer the same problem of adjusting our speed down when we come to towns and dropping to 50 km There must be a name for it . My brain and eyes have to adjust . 50 km seems as though you are driving at walking pace after hours of higher speed .It was very hot up in the high 30s everything was hot even the windscreen and side windows . One of the first things I did when I brought my Defender was fit a raised air intake , there's no doubt these help , pulling air from down by the wheel is poor design . As for foot-well getting hot ? I think it just heat from the engine and gearbox . Lets face it they don't have the best insulation . Next time I do a trip like this I'll be looking at extra insulation , Maybe some carpet underfelt ? The thing is if you leave it in and it gets wet , it rots out and stinks . As for fuel I suppose I could have saved some $$ by driving slower . I found driving at the same speed as everything else , I didn't have B doubles overtaking me , It just seemed to work better . My Defender sat very comfortable towing at 110 km revving at 2.3 rpm . Jim

I lagged the exhaust on the Puma for those trips through spinifex country as it gets packed behind the exhaust which crosses the vehicle. We had it starting to smell as if it was just about to burst into flame on one trip and that made me decide to lag it.
It's also helped keep the cabin cooler as the floor doesn't heat up nearly as much on long runs.
Of course our D4 doesn't suffer from such things......

I would just like to stop the hot air coming in through the handbrake, but I wonder if this would help move the aircon around the footwear better.

I noticed the footwell, gearbox side was quite hot when doing long runs in heat. I was thinking about lagging my exhaust too. Makes a big difference?

Alan that's good advice , I suppose we all suffer a hot floor especially driving when the temp is up in the high 30s . That's both foot wells !!.. Jim
