So I just installed a new thermostat, and while idling the truck, new thermostat installed, I did not see the temp gauge coming up at all. I plugged in my computer and could see I was operating at 180 degrees and the gauge still read dead cold. The thermostat is installed correct (spring side down). I have no leaks at all, the heater core hoses are both hot and the upper radiator hose is cold.
Any thoughts?
