The answer is that temp gauge led is first and foremost an "over
temperature warning" led.

The coolant level warning aspect was added on later as a secondary
function of the same led.

Also the coolant gauge temp sender is absolutely NOT the Temp 1 sensor.

The Temp 1 sensor is in the AFM to tell the ECU the intake air temp.
