DOES THE GAUGE CYCLE QUICKLY OR SLOWLY IF IT'S SLOW THAT IS NORMAL AS THE COOLING FAN CYCLE ON AT 220 -225 AND OFF AT 190
I had the same problem and it eventually let to a blow head gasket. The solution is to change the air filters that are in a compartment inside of your dash. I know this sound silly but open your glove compartment and there is a place on the back that opens up. Do this and you will find 2 filters inside and if they are anything like mine they will be full of pine needles and leaves and all kind of other debree. Now my temperature hand does not hardly move even when idled (It used to get in the red at a drive thru) and my air freezes me at 1. Hope this helps.
