Noticed it yesterday. Light kicks off once the engine is up to operating temperature.
Radiator and puke tank are both at proper levels. I haven't spotted any leaks. Bad sensor?

Thanks.

Probably not a bad sensor...just dirty. If the light annoys you, you can unplug the harness from the sensor.

Fixing it involves draining the radiator fluid, removing the sensor, cleaning it, refilling the coolant, etc.

The sensor was dirty in our old Regal GS and cleaning it solved it. The light was also on in our Firehawk but I just unplugged it since I don't want to drain the fluid and make a mess in the pristine engine bay/undercarriage.
