when car idle coolant goes to 200+ degrees

[N9QGS]

OKay I appreciate it, like I sad its been in the 50's and It can creep up stopped at a long traffic like to the point the fan kicks on (200), and I just thought it was odd that turning the air on would being it back in check, never been in heavy stop and go traffic, just a random light shortly after driving the car for 10 minutes that day or after 2 hours on the highway and coming up to a light it does it, I wont pursue it. but now that I know the fan is coming on then I know why its cooling down. and that Im not at a high level even at 200 degrees to be concerned with, so Im glad to hear those reports. Glad to know after 135,000 I still can't find anything to repair on the vehicle besides my normal maintenance items. hahaha
