I live in Socal, so not super hot weather here, and my gauge seems to run
about 1/3 up, well below the red light. Is that normal? Is my van running
too cold? It will go up to half, over the light, in city driving, or if
stopped for a while. The thermostat was replaced not long ago. Also, I
recalled when I was driving on a trip through a colder area, say 10-20
degrees F, the needle would be way down there, almost nothing, is that
normal or is my thermostat not working right? or was it due to me having the
heater on?
