Low coolant light
         Yesterday the low coolant light came on
I stopped and check the coolant level, unplugged and replugged the sensor. Light turned off
Last night again low coolant light came on and started blinking and sounds bib. Bib. Bib….
I checked the sensor and again unplugged and cleaned it. Still no change except the engine light with a wrench came on. I bought a new sensor and plugged in still same problem. Coolant level in hot and cold engine has not been low at all.
Any input will be appropriate.
