    Yes it sure put the monikers on an otherwise very pleasant trip, I recon I lost 3kg in sweat

    I have done a bit of "Tinkering" over the last few days and have managed to take the Titan rear drawers out of the D2a and fit them sideways on the navara, i have wired up the spotties, fitted a couple of led reversing/work lights, fabricated a back rail on the tray and have given the truck a service.
    I have yet to replace the oil in the diffs, transfer case and gearbox and fit a blanking plate in the EGR to stop the usual Navara "smoke ring" on acceleration.
    I also have yet to fit the second battery and fit the 160w solar panel with 2x standalone 125AH batteries with solar regulator to power the 2x 12v fridges.
    I should have everything done by the new year and intend to head up to the mouth of the Fortescue river for a few weeks fishing in Jan-Feb

    My daughter has volenteered to detail my D2a for me, God bless her and I have organised the rear end repairs to be done at Whyatts and am now awaiting the approoval from my insurer for the windscreen and plenium to be done at Whyatts as well.
    I will refit the 2nd row seats and fit the new lower temp thermostat and take the old girl out on the tracks as soon as everything is fixed

    I'd be curious as to what temp the Navara(coolant) will sit on when towing a 1.5t load in 40C heat too.

    I dare say it'll be a bit over 100C(if my memory serves me correctly).
    Cheers,

    I'm not sure as I haven't towed in that sort of heat yet But my nephew has the same model/year Navara and he regularly tows a 16 foot fiberglass boat (Which is heavier than my 5.4m trailcraft ali boat) and hasn't had any overheating problems with his during our 40c+ summers.
    The Disco is 15 years old with 270,000k's on the clock and the Navara is only 7 years old with only 100,000ks on the diesel motor so it has a much better chance of surviving the boat towing work.
    The Disco Can do the job But it IS getting a bit long in the tooth and I don't want to kill her by making her work harder than she has to and there is no way on earth I am going to suffer having to run the heater in 40c+ conditions ever again just to keep the engine temp down.

    I could do the inline thermostat mod to the D2a which would be great But I am unwilling to put anymore money into an already very expensive project that has cost me well in excess of $10,000 in repairs over the last 3 years.
    The Disco will be used and enjoyed But it is No longer my front line 4WD unfortunately.

    I think there should be a clear differentiation between 'overheating' and running hot!
    Most modern engines do run quite hot nowadays .. apparently for better emissions or something.

    Before brother bought his Td5, he had a Patrol(4.8lt) and it ran consistently at just a wee bit over 100C towing his 500kg trailer(in 40+ degree heat).
    Granted it did finally burst hoses and stuff, and caused him(more so myself) grief on one trip .. but that turned out to be more about a non working viscous hub, than overheating due to normally high operating temp.

    The D2a was getting up to 105c-106c and only when I turned the heaters on and dropped my speed to 80kph did it drop to the high 90's.
    The outside temps were 44c-47c and the 79 series we took on the trip didn't bat an eyelid towing a 2.5t 20 foot van and the tray loaded up to the hilt.
    There comes a time in every cars life when some TLC and cotton glove treatment is needed to keep it running and for my D2a that time is now.
    Running an aluminium block at consistently high temps has Never been a Great idea and the old 4l rover V8 petrol engine with its liner slipping characteristics is much more prone to failure than a newer steel block diesel engine running in adverse conditions.

    I am almost certain that if I took the D2a on another 10,000k trip up the top end it would be its last "Hurrah" and I don't want that to happen to her

    I understand the frustration with the D2, but you don't say what temp the troopy was at too tho.
    That is, you fear 100c temps on the LR, but I'm quite sure the troopy would have been as close to those temps, if not higher.

    My now thankfully gone Holden Frontera(3.2l Isuzu V6) would run well into the 105's on a hot day(35+) .. not towing.
    Never caused the motor any issue either.

    When you rebuilt the V8, did you rebuild the block too.. ie. stuff like top hat liners and so on.

    For me, 100-110C coolant temps on a very hot day isn't an issue .. you just accept that. I can't imagine any vehicle under load in such conditions not running such high coolant temps.
    Closer to 120C for me is my worry, as this is too close to the boiling point of the coolant under pressure.

    If you don't have an OBDII type plug in doodad, I suggest you try one. I got mine years and years ago when I had my Frontera(ABS codes issue) and gives you a good insight as to what's going on up front there.
    Just get a cheapie one of ebay, more likely to work than not .. hook it up to Torque Lite app on a phone, and it should give you some gauges to work with on the troopy and navara.

    ps. the reason I question your comments is that I have run my old aluminium blocked RRC many years ago .. consistently at high temps .. but unknowingly, not deliberately.
    On one trip, to the Rock, car ran fine and dandy all the way up. Next day after a sleep, it decided to 'run hot' .. LR temp gauge right at the start of the red zone .. we all know .. means engine is toasted!
    Anyhow, changed thermostat .. nothing. pulled thermostat .. nothing. Still had near on 5000 klms to get home.
    Ran home some of the way with the bonnet partially open, ran cool. No worries I thought. got to Pt Augusta(maybe Marla) I could sense it was running cooler. so removed the box wedge propping the bonnet up .. that was 'getting me home'.

    So getting home, first thing was do do some checks .. remove spotties, etc, viscous fan .. all manner of stuff, car still ran at the red zone line. Mechanics found nothing. tested the sender, changed the sender .. basically found nothing wrong.
    2 years later, with the RRC still running at the red zone line!!! .. one day I was doing stuff, and accidentally rubbed my hand/arm against the rad .. expecting the usual cuts and grazing, but instead got plenty of copper dust!
    Rad was done and dusted. Rad was supposedly checked by the mechanic 2 years ealier, and given the OK!
    Anyhow, fitted a new rad, coolant gauge now back into the normal middle zone!.
    I ran the poor old RRC at the red line for over two years .. engine never complained.
    Mind you I'd estimate that the issue started at about the 400+K klm mark .. I had to park the RRC up many years later with just over 650K klms up(I had marked the 100K units inside the dash pod) .. engine was original from the factory.
    Other than the odd seal here and there, I'd never touched that motor.

    ps. it was finally put to rest only due to the massive rust in the driver footwell. Say under a tree once it was parked up, waiting for me to do something with it, but dad chopped another tree down, and parts of the other one fell on the RRC, smashed rear, etc.
    Cheers,
    Arthur.

    Because my initial engine problems were caused due to overheating I fitted a low coolant alarm AND an OBD2 device so that I could monitor the engine temp in real time Not that bloody useless factory temp gauge.
    The D2a IS Old But it isn't dead yet and that's the way I want to keep it

    ....
    Hearing 'ya re the temp gauge.
    I fitted a VDO sensor and gauge for my Tdi.
    basically: from roughly 70-ish up to about 115C .. needle sits at the same spot about half way.
    At 117(hottest temp I've seen yet) it nudged up about 1-2mm .. to just over half way.
    I only ran it up to 117 for about a min, maybe less .. more so to see where it'd go .. wasn't game to see it at 120!

    backed off, A/C off, and it cooled quickly back to under 100 .. maybe a min or less.

    Never lost a drop of coolant tho. All day, up between Cobar and Broken Hill 40-43C, very dry heat too(I think is much worse than humid heat) .. but after I got home, checked stuff(oils, coolant etc.) and all good.
    Just found one leak from the annoying vacuum pump design, one welsh plug, filled that over with some silicon goo .. and it's held well since.
    Cheers,
    Arthur.
