Engine Temperature

[hummerabia]

My '07 runs constantly up to the 3/4 mark during the Arabian summer however never gets any higher than that, and we are talking 48 degrees celcius ambient temp in town. Out in the desert it frequently tops about 55 celcius but very little relative humidity and so far have not experienced an AC shutdown owing to high engine temp.

Ran a test last year with my '06 H3 and a guy from GM in his H3 in a mad heat of 56 degrees all afternoon with the AC on with no overheating issues so I guess you can say they got it right with the cooling system.
