    Default Engine Temp, what's normal

    Was out driving around most the afternoon in 104-deg heat with 60% humidity. Hot for sure.
    A lot of stop-n-go driving, waiting in lines at bank, etc. A/C going full blast the whole time.

    I noticed the temp gauge would rise to about 210 F at idle when sitting still for longer periods, not just a stop light, but would return to around 180 F when moving around. It does have a 180 F thermostat installed (very recently).

    Could this be considered normal for the conditions, or does it indicate some possible problem?

    Of course, 104 with A/C and sitting idle is about as rough as it gets.

    I would not worry about that at all, if the temp were to crepe up around 225-240 deg then id starts doing something.
