Low coolant light

[tkelly35]

Mt low coolant warning light came on. Coolant was not low. I replaced the sensor. The warning light is still on. Any ideas about what to try next will be appreciated!

my 21 at 65k did the same with the light, my buddy's 19 did the same thing around the same miles. It resolved for both of us by adding a small amount to the reservoir. Sounds like you have more going on if that was already done and you replaced the sensor.
