My coolant level low light just started to glow dimly as soon as I start driving. I've check the level several times and the overflow tank is full to the proper level. Temperature gauge shows that all is well in that area. Could this be a bad sensor, or should I look farther?

Thanks,

You will have to replace the coolant level sensor. If the level is full, the sensor has started to leak internally.

Good luck.
