My 180 degree thermostat opens at 175 and my 185 on / 170 off fan thermostsat
kick the Viper fan on at 177 degrees. These temps are according to the
scanner readings (and it's a brand new sensor). Since the thermostat opens early
and the fan kicks on early, the coolant temp never exceeds 177 degrees on an 80
degree night. During the day in 92 degree weather, it will climb to 185
degrees. These are all with the Viper fan on low. It gets a little hotter when I
idle for a while.
I know there is an optimal operating temp. and if it doesn't reach it, it
will stay in open/closed loop or something. Can someone explain that to me
please?
Thanks,
James
