Well it could be a leaky thermostat housing. That is usually removing two or three bolts and a gasket and change the thermostat while you're in there. If you want to really be sure buy an ultraviolet leak detector.You pour a packet of special dye into the coolant. Run the car for a few trips then, when the engine cools down, plug the light onto your battery and start looking. Any external leaks will glow bright neon green. Even leaks that are so small that they dry up when you shut off the car can be found this way.

Add coolant 2002 s class


When engine cold , find coolant reservoir , usualy of white or yellowish container with black top and cap.
It has marks on it FULL and LOW.
Fill it up to FULL level and you done.
If it does'n have any coolant in there , then fill it up and run the engine for few minuts with open reservoir cap. Keep filling it up if level goes down , once it's stop or start to going up, close the cap and drive it around the block ,cause they have self bleeding cooling system.

Warning light?


That is the low coolant level indicator. Check the coolant level in your radiator and or reservoir. Add a 50/50 mix of antifreeze and distilled water. If you want to get an owners manual go here and sign up. http://www.gm.com/gmownercenter/gm/?campaignId=&vin=

Does the arrow point down. I think you are describing the low coolant level light. Add some antifreeze.

Blue low engine coolant temperture indicator light is on


I also recently bought a 2002. According to the owner's manual the blue light does not indicate a problem unless it stays on after the car warms up. If you have an automatic it will not shift into fourth gear until the coolant warms up at which time the light should go off. Have only had the car for a week and notice the blue light goes off after a mile or two of driving in temperatures in the teens to 30's. I don't know how much outside temp affects it.

2002 oldsmobile alero coolant light and fuel


You must always check the coolant hot, expansion will cause a big change in level, how low was it? top it off hot and then drive a few days and recheck the level, I don't think you have an issue here.
