I drive a 98 grand marquis, the temp gauge keeps going from the middle all the way to
Red (H) then boucing back down and up and the red temp light is on but its not smoking, doesn't smell
And is driving fine... Is there a change the gauges are messed up and its not overheating or is this
The call before the storm?

There is always a chance your gauge is bad, small chance. Have you checked your overflow tank, or your radiator? Start with the simple easy steps.

Make sure the air is purged from the system.

Check the temp sensor and the thermostat
