Unplug the temp sensor and ground it. Then turn the key on without starting it.
The gauge should go full hot. due this just to see the gauge raise. If the gauge
does go to full hot replace the temp sensor. Be sure that you did burp the cooling
system.

Remove any air in the cooling system. Otherwise you won’t have solid water
from air pockets and it can affect sensor readings.
