The Mirage usually sits at 192-197 normal operating temp. But today, it was dropping all the way to 165-168 at stop lights.
That is normal in these conditions but without any gauge you will never know it.
Lovely weather
I've noticed the same thing. Especially when I have my heater fan running. The engine isn't working nearly as much, so doesn't generate as much waste heat.
I'll keep my heater fan off as long as I can tolerate to get the coolant temp up on my short commute. I'll often turn on my heater fan at about 165℉ (74℃.) When I do, the coolant temperature drops.
