Coolant temp gauge
Hi guys, I am new here looking for help.
I have a 2002 supercrew 5.4 triton. My coolant temp gauge is acting up. When it starts up its obviously in the cold range but when the truck begins to get up to temp, the gauge only goes up 1/4 full.
Any ideas as to what it can be?

Thermostat come quickly to mind.
The gauge is driven on a secondary basis by dash electronics.
The other possibility is the head temp sensor may be out of calibration.
Normal running temp is in the 195 to 200 degree range.
Good luck.
