2004 Impala SS - SC 3.8l engine.
I'm running a 180 degree thermostat and have the fans setup as in the photo. (Sorry for quality)
But I occasionally notice in traffic, etc the temps climb upwards for 212-215ish. Yesterday I managed to pull over when they were at 214 and neither fan was on. (AC off). Turning the AC on does make the fans turn on.
Is there some wonkyness with the settings in here?
