I am not a car guy, but my low coolant light just came on in my Saturn Vue. I checked the owners manual and it said I should add anti-freeze/coolant. If you go to a car parts store (NAPA, Auto Zone, Pep Boys), they can tell you what type of coolant to add. If the problem repeats, you probabaly have a leak in your cooling system. Good Luck!
With an OBD2 scan tool.
The light will be on the left side of your dash. It will look like a box with a wavy line towards the top (to reperesent a liquid)
Check coolant level in coolant recovery tank and radiator
Its a bad low coolant sensor. Common on these Chevy models.
Replace brake light switch.
The check gauge light on the 1994 Chevrolet Caprice comes on because there is something on the gauges that requires attention. It is a good idea to take the vehicle to a mechanic when this light comes on.
There is a sensor either in the coolant recovery jug or the radiator side tank that is defective.
bad coolant level sensor in either side or bottom of plasit coolant resivoir,
Under the instrument panel..Its a 15 amp one...
There is a low level sensor in the side of the radiator. They do go bad.
Check the brake light switch. It is defective or out of adjustment.
Check your coolant first, if it's not low then replace coolant level sensor
