2005 Cadillac DeVille Question: check coolant light keeps coming on

coolant level checked-found to be okay light keeps coming on -
Answer 1
The coolant level sensor is in the coolant reservoir and is a fairly high-failure item. Temporarily unplug the sensor and see if the light goes out. If it does and comes on when connected and with the reservoir full, I would bet on the sensor. Unfortunately, I think you have to buy the reservoir to get the sensor. -
