Question about 1994 Cadillac DeVille
How can I check if the pump is working or the air bags are leaking?
The stuts you call air bags is just a visual inspection
Push up the dust covers or boots to see any rust or leaking
The compressor you can unplug & jump to 12 volts or
jump at the relay to test it

SOURCE: Water Pump
If you have the NorthStar 4.6L engine this is going to be the easiest water pump you ever done and even if you have not. Auto Zone will be able to help they have a special tool for removing and replacing it. I would suggest replacing the hoses when you do this also. When you get the pump you will also need a O ring for the pump cover, and a new thermostat. get the proper antifreeze also.
Auto Zone should also have some instructions with pic's to help you.. email me if you have any questions.......

IT MEANS THAT A FAULT HAS OCCURED IN THE SYSTEM AND THE SYSTEM HAS BEEN DISABLED, TO FIND THE FAULT YOU MUST HAVE THE DEALER TEST IT FOR THE TROUBLE CODE THAT IS STORED WHEN THE LIGHT STAYS ON.

The coolant light means the car is low on coolant. You must have a small leak somewhere. Go to your Cadilac dealer, or an auto parts store and get a gallon of anti-freeze (coolant), mix 50-50 with water. Somtimes you can buy it premixed, but it usually costs more. Put a jug of it in the trunk and add some when the light comes on. The owners manual should show you how to do that, or have someone at the dealership show you where and how to add the coolant. You may want to have a mechanic check it for leaks.
