Re: 98 deville low coolant level message
If the coolant is at the tank seam line (midseam) and the "Check Coolant Level" message shows, then the float is stuck or the sensor (reed switch) in the bottom of the surge tank is dead. A 2-pin plug in the bottom of the tank. Check it. If the coolant remains at the midseam and the message still shows, then you might be in the tank replacement business - Amazon Automotive - about $60 shipped, including the sensor.
Remember - the proper coolant level, cold, is NOT "full"; it's at that tank midseam line.
