Question about 2001 Cadillac DeVille
2001 Deville info for me to check coolant; I've added a little to the resovour tank which satisfies the info system, however, this added amount will usually be expelled when driven at operating speed. Could this be a bad sensor or computor adjustment problem?
Are you saying you need to add coolant often? If so you need the leak found and repaired.

First, provided their are no visible coolant leaks and/or loss of coolant with no signs of leaks, I would thoroughly flush cooling system and replace coolant, then check and/or replace thermostat (you can place thermostat in boiling water to check for proper function), if you have tried these 2 steps and still are experiencing overheating you may need to replace your water pump which can be a tricky job if you're unfamiliar and try to do it yourself, however, I could walk you through it if necessary. Also visually check your radiator hoses for bulges, wear ,etc along with heater hoses etc. You may want to also check radiator fins to see if they are dirty/obstructed and clean if necessary. Let me know if I can assist you further and how it works out

No the light is linked to a sensor. There is a coolent sensor that tells you that the level is low. It sounds like the sensor has gone bad. And the sensor is located in the coolent tank. If it is bad from my understanding you have to replace the whole tank. But take a paper clip with the engine off and disconnect the wire harness from the sensor and jump the wires and see if the light goes off.
