    The temperatures up here are ridiculous atm, 40 degrees and humid etc. Car was fully loaded, few items on roof rack including spare wheel etc. Hard conditions for any cooling system.
    In my rig I have an in hose temp gauge fitted post thermostat, and an engine watchdog (sensor bolted to side of engine block). So I will give readings for these plus Nissan factory gauge position.

    At low speeds, town driving and 4WD high range dirt:
    Hose: 70 ish degrees
    Nissan: 1/4 - 1/3
    Watchdog: 80-90 degrees

    On highway, 90-100k's an hour, middle of the day with air-con on
    Hose: 80-86 degrees
    Nissan: 1/2 - just below 3/4
    Watchdog: 95-100 degrees

    In cooler conditions early morning etc the car runs cooler.

    I'm keen to hear how other peoples figures line up next to this, I feel like its running a little hot? But it could just be in my head and the fact that ambient temperatures are through the roof. If I start to push my speeds more than 90-100k's in the heat the gauges creep up instantly so I just tinker along at lower speeds. Then every now and again other GQ's also loaded up to the max go screaming past me with apparently no dramas whatsoever so am I just going mad with too many things to watch over haha?
    Today cruising back from Mildura fairly warm ambient temp driving at 110-120km/h my temps got to 105 with probe in top thermostat housing. If i dropped speed to 100km/h temp would be around 100 degrees or just under. Normally around town sits around the 80 mark +- 10 degrees.

    Cheers Sooty! You running a TD42 in your GU? Where does your factory gauge sit when temp is at 100ish out of interest?

    Yeah factory TD42T mate, non intercooled. Factory guage s sitting up 2/3 ish when around 100, but sits up 3/4 when around 105. Sits there quite stable and doesn't climb excessively quick. That was with the AC running too.

    Cheers mate! Thats what I was hoping to achieve as some of the 'easier' stuff tends to be covered in no detail which is daunting when youre having a first crack at something.

    Sorry to dig up an old thread but Wicked write up ashmccormick!
    Just doing an overhaul on my TD42T at the moment and was wondering what the go with the engine coolant sump is when putting it back in?
    Is it based on a torque setting? And if so what torque? Don't have the service manual so im not sure and when i went to take it out originally i could still see thread on the outer of the bolt; if that makes sense.
    TIA

    Todd, are you referring to the engine coolant drain plug?
    It will have thread showing because it's a tapered thread that you can't screw right in.
    I use a short stubby rachet to tighten mine with one hand after putting some RTV silicone on the thread.

    Hey jff45!
    Yer i was referring to the engine coolant drain plug. Ahh ok, so basically just make sure its in tight enough to create a seal - doesn't need to be torque specific.
    Thanks for your help mate, appreciate it.
