SOURCE: im receiving a check coolant
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.

SOURCE: 99 Cadillac Deville Coolant Leak
Most likely a cracked block or free plug that came out or loose. Other options are hozes, which I believe the dealer would have fixed. A third option is the water pump itself.

SOURCE: 99 deville head gasket leak?
A head gasket leak is usually indicated (among other things) by continous overheating of the motor, and subsequent loss of coolant.
It can also be indicated by the presence of engine combustion gas bubbles in the coolant resevoir.
Ensure the coolant system has no external leaks, such as faulty hose/s, radiator etc.
Ensure motor tune or other motor mechanical condition is not the cause of overheating.
I assume the motor is actually running hot.
Check cooling fans are operating ok (as necessary when car warms up):- if not check
2) relay operation,
3) heat sensor switch.
Check/replace the thermostat,
Check the coolant pressure cap is serviceable & of correct rating,
Ensure cooling system is correctly filled, bleed off any airlocks as necessary when re-filling,
Ensure radiator hose on suction side of waterpump is not collapsing at engine revs above idle (due softening),
If the motor has been severely overheated, the head gasket could be blown - look for combustion gas bubbles in the coolant resevoir.
