    Radiator and Thermostat have been changed (Ended up finishing in the moonlight.. was somewhat soothing). I've taken her for a drive and everything looks great.

    Obviously ambient is only 15-18 degrees so not a massive test... but I was overheating today with 22 degrees ambient temp within 3-4 minutes of driving.

    I'll know more tomorrow when I pickup some New Tyres.

    So, was it the radiator or the thermostat that fixed the overheating?

    Well thats the question. I always replace them as a pair anyway (because Thermostats are soo cheap) that I don't know....

    Guys:
    Curiosity got the better of me and I decided to Crack open the Plastic Header Tanks at the Top and Bottom of the Radiator.

    Top of Radiator had about 50-60% of the Vents closed with gunk. Bottom looked suprisingly ok... but I guess thats because the cleaning gunk could run up and around freely.

    Would suprise me if the insides of the Vents in the Radiator were clogged in some cases as well.

    So I'd probably think the Thermostat is ok... although in saying that I'm binning it anyway

    For around $30 it's not worth the risk (and time) to keep the thermostat.

    I have t-hatted the engine, new water pump, radiator, thermostats and guess what above 35 engine starts to get hot. I think the heat coming from the condenser when aircon also plays a role even when the cooling system is in good order. Turning the aircon off on those really hot days solves the engine cooling issue just not the occupants

    I'm actually looking forward to a 35 Degree day again now myself... just to see if I have actually solved the issues or not
