Default Why does the "LOW ENGINE COOLANT LEVEL WARNING LIGHT" keep going off

This light keeps going on and off, the car is not overheating, however when I look right infront of the driver side front tire where the revervoir drains, its wet and smells like anti freeze, I keep adding water just to be safe, but I think I might be fillin up the reservoir too much. The problem with that is that even if I leave the reservoir alone after driving 100+ miles the light will keep going off, without the extra water in the reservoir, what is happening and how do I fix it. Will an flushing the radiator help, there are no visible leaks anywhere in the cooling system.

If the radiator cap is old, try replacing that first. May need a new sensor if all else is correct.

I'm not positive if it works on the LS, but on the SC's just unplug the sensor and the light will never come on again.
