I just went out and started the truck and let it run for about 10-15
minutes. I removed the radiator cap and stuck a meat thermometer in to
check the temp. The temp is sitting right around 190 degrees which is what
the gauge is showing. I can also see the coolant clearly moving through the
tube. This tells me that at least the pump is pumping the water, the t-stat
is opening to allow the flow, and the temp sensor is at least showing the
correct temp right now. Not sure what to check next.
