Chevrolet: light in the instrument panel?, camaro z28, pressure test

Question
I have a symbol that lights up in my 1996 Camaro Z28 instrument panel that didn't light up before. It looks like an arrow pointing down with a square around it and some wave currents beneath it. I don't know what it means. Thank you for any help you can give regarding this matter.

Answer
Hi Joseph. hope you had a gr8 day!
This light is triggerd by low coolant in the rad.There is a sensor 5 inches down on the passenger side that will trip when the coolant lever drops below this part.
You may have a leak in the rad or the coolant has burned off to the point where the liquid level is now below the sensor, and this is telling you to check the rad.. (****please do this when the rad is cold****)
Fill the rad up to top and this will clear the light..but getting a rad pressure test is the best way to find out where the fluid is going.
