It is easy enough to test the gauge circuit with $1 pack of resistors
from RadioShack. Then you will know if the cluster  or some part of it
is the problem. I will help any owner do this testing on their own van
if they will get the resistors and send me a photo of them holding them
in front of their van.

100 ohm, 1/2 watt
part number 271-1108 for a 5 pack

After he installed the new sensor the gauge on the dash pegged on the high end and the red light is blinking.  He replaced the thermostat and used the thermal gun to check the temps and all the numbers check out just fine, despite what the gauge is indicating.
