Low coolant light comes on for a few seconds during driving then goes off

Recommend filling coolant reservoir (plastic jug) to proper level .. That should be something you can do.

Hello, Just to add to that, please DO NOT open the coolant reservoir or radiator if the vehicle is warm. This can scar you for life. There is nothing scary about it, just add coolant or distilled (bottled) water in the morning before the engine has been run. Safe and sound. I recommend adding distilled water instead of coolant so you don't have to observe the grade. Besides, a little bit of dilution will hurt nothing. If you find the coolant reservoir continuously loses fluid, just take it into one of the certified shops in your area for diagnostics. http://repairpal.com/chevrolet-within-10-miles-of-atlanta-georgia-30345
