In the OK summer mine runs 200 (one mark below 210). Here lately it's been cooler and it doesn't get above the first quarter mark unless I run it hard.

I run over 200 in Florida heat while towing loads on the highway. Should I be worried ?

I live in AZ and my gauge was reading like 205* so i got worried about it and bought a Edge Juice with Attitude and the Edge moniter tells me it is running 189* while the temp gauge on the dash reads like 205*

my Edge tells me im running 175-200 most of the time, this time of year im seeing 180 most of the time

and agreed that the factory temp gauge is worthless, only really good as a dummy gauge....tonight my gauge said 180 and edge said 160 while i was still getting warmed up
