The problem is the low level sensor.It is just below the radiator fill neck.About 3 or 4 inches down on the passengers side.It is held in by a wire clip.The best way to replace it is to let the cooling system cool down so there is no pressure build up.There is an o-ring for a seal.What I do is lube the o-ring seal before installing the sensor so it goes in easier and the o-ring will not slide off.You can partially drain the coolant just below the sensor level or just remove the sensor and install the new one.You will loose a very slight amount of coolant if your quick enough.You should be able to get one at any part store and it should not cost to much.You can call ahead to the part stores and tell them your make and model number along with the engine size.I hope this helps and good luck.

SOURCE: Low Coolant Light Staying on
This car has sensors on it. If the coolant tank is full and the system is working properly, then one of the sensors is bad.
Have the cooling system presure tested to make sure you have no leaks. If test is good, then look to the sensors.
GM has different systems for each car depending on configuration, so it is hard to point to the one that may be bad.

Your thermostat may need replacement - they need changing every 2 years. Here is a link http://www.jagservice.net/jaguar_v8_secondary_tensioners.htm

the sensor is bad but you cant disconnect it it will still keep the light in, you could try disconnecting the switch and run a jumper wire from one terminal to the other and loop it ,that might turn the light off,might
