Average running engine temperature?

I would like to know what the average temperature my coupe should be running? Recently I developed a leak in the radiator and after getting it fixed, I find myself watching the coolant temperature more often. What would you say is normal for driving approx. 100 miles on a hot summer day (around 100 degrees or so)? I have noticed that it runs usually between 189 to 198. However, when I am stopped at a red light, etc. it goes as high as 210. Is this normal or did they not fix the problem??

that is about what mine runs. your engine temperature is greatly affected by your speed (or lack there of) and how
hard you are working it. the outside temperature doesn't affect it nearly as much as those other two factors. if you
are at a stop there is not a s much air going through your car's radiator which prevents it from operating at full
potential. and naturally if your floorin it at high rpm's the engine will be hotter then it probably enjoys.

i have a 2008 Chevy Cobalt LT Coupe and it ranges from 185 to 198 as well(today was a hot day, mid 80s).  It went up to 205/207 in park.  I was wondering the same thing. I thought my car was overheating(I'm used to seeing a "Needle", like on my '96 cavalier). Good thing I'm not the only one.
