    His Gu doesn't have a pollen filter, I can confirm this as I helped inspect his heater box as a/C drain was blocked. I believe in Australia some on the y61 patrols were never released with pollen filters...

    yeah my 2011 gu didnt have a pollen filter so i just bought one and cut the slot out where it goes and it just slides into position . there have been posts about it in the past as others had done it as well . i just thought it might be a posibility as to why mb's heater dosent work ,and on that , how did the heater core look . others in the past have have said that theirs have blocked up and they have cleaned them , some by removing them completely from the car and some whilst it is still in the car although i can't recall how.

    Nah Ive tried four different brand stats. Same result. currently using a Tridon Hi flow one as it seems to cool faster is the warmer months.

    It is my belief too that old diesel donks seem to prefer running hotter than 76.5C coasting along at best I’m experiencing this winter.
    Our 8.3 work Cummins sits all day on 85C and so too I believe our Louisville tipper.

    I will be interesting to see the results if you decide to change it.

    Back home now to Family GU Land. Certainly was cold Acco 8.3L swagging western goldfields last nights -2C. Coupe clear stars morning dunny dumping buckets froze a 5mm crust :-)
    Appears we’re jumping back up into double digit ambient temps finally back here but will still find time next week to muck around with the TD27 88C as first test

    A quick pot test on the TD27 88C.
    (21200-05D12)
    Interesting results, isn’t fully open until 98C and fully closed again until 83C.
    Was expecting the 83C shutdown (5C below setting) but 97-98C until full open is right up there Russia :-)




    On the way back down now to 83C fully closed again.

    Installed results are in now for the TD27 88C thermostat folks.
    A quick snippet below of ambient temps again for not confusing here hot climate TD42 owners.

    Most noticeable was letting it idle for 1 hour after being installed.
    It sits exactly on 88C whereas prior would winter idle at 60C as per my previous posts pictures.

    Coasting down big hills here the lowest it would get was 86C whereas previously it could get as low as 56C found.

    Giving it an absolute flogging at horrible 550EGT’s up our biggest hills the highest I could get it was 94C.

    Basically cruises along at 100kmph flatish highways at these ambient temps hovering between 88C <>90C depending on pedal load and recovers incredibly quick to 88C.
    Heater is insanely good now and I swear this old truck has more responsive power than before up here in this fresh mountain air

    FWIW: Tested the removed tropical 76.5C thermostat earlier whilst letting the new 88C get up to idle temperature.

    Ever so slowly started opening at 77C.

    By 84C still had a long way to go.

    Appeared at its max open by 91C

    Cooling down was still a long way open at 71C

    Didn’t really look fully shut until sub 68C.


    I do have a new spare summer 76.5C that I will test to see its results for comparison ASAP.

    Just ran the pot test on a brand new OEM tropical 76.5C.
    Nearly identical movement on the rising temperatures as per above although quite interesting that it was at full shut again at 74C unlike the old one at 68C shut!

    Just goes to show I guess there’s more to thermostats than being black and white issues like full open or shut stuck!
    Quite the 6C variance in closing times found here :-(

    FWIW: Just ran a final pot test on the TD42 OEM 82C. Dare I say this one might end up being my southern regions winter & summer all rounder choice hopefully

    Seemed to start opening a whisker late at 84C.

    Half open by 88C.

    Full open by 92C.

    On its way down half open by 80C.

    Full closed by 77C again as apparently should be OEM 5C below manufactured opening set temps I believe?
