    If anyone that has a Scanguage II would please tell me what their coolant temp. is running on a 2010?

    On my 2007 the Scanguage at highest was 181-2 degrees, now with my 2010 the Scanguage shows 191-3 degrees, does this engine run about 10 degrees hoter than the 2004-09's?

    I would appreciate any input, thanks.

    If that's all you saw, you likely had a broken thermostat (one that constantly remained open). 191-3 was the normal high you should have seen.

    191-5 is the norm for the 2010 model.

    Thanks that is what I wanted to know. It is possible the 2007 was wrong because that is the highest it ever got and that was a few months after I bought the 2007 and bought a Scanguage II.

    Happy to know the 2010 is running in the right range.

    Rarely exceeded 185 degrees in my '05.

    I'm now regularly seeing between 190 - 198 degrees in my new one.
