I have cleaned the exterior of the radiator and since then the thermostat coolant temp never goes above 1/4, when cold it does return to the cold side on the gauge. I did check the dash cable and it did move the slider for the water valve and I did start the engine and watch to see that all of the buttons moved the linkage for the ac and defrost and the other buttons all worked. I also went and bought a infrared thermometer and I will check the temp tomorrow, I also turned on the engine block heater a couple of hours ago and the top of the radiator is warm to the touch but the heater hoses are still cold and I will go out in the morning and start the engine and check the heater hoses both at the engine heater shut off vales and at the heater.
