I have a 2001 Saturn sc2 that was overheating do to a heating hose needing to be replaced and low fluid in radiator light would not turn off. I bought a new hose and clamps and decided to flush out the radiator and fill with new dexcool antifreeze. I figured all would Be good, but now, the light continues to read low fluid in radiator and its full.
Ensure your radiator reservoir is also to the full line, this is the location your low coolant sensor is located not the radiator. Having this 'jug' filled should turn your light off, please write back with further questions. Hope this helps!!
There is a procedure to purge air from the cooling system.
I'm suspecting there is air in the system and there is no coolant in the overflow container - and you need to do your research on how to finish the flush correctly.

In the overflow reservoir there is a float that has probably gotten stuck. Tap on it and that should do it.

I would have the cooling system pressure checked. Also, most mechanics replace the thermostat after a vehicle has over heated. Once certain items in a system are damaged and replaced, especially items that could leak fluids or that are under pressure, it adds more pressure on existing items in the system which could create leaks elsewhere.

I am assuming the light you are referring to is the low coolant light. Many times the switch inside the reservoir will stick to the bottom of the reservoir. Sometimes tapping lightly on the reservoir (with your hand or a rubber mallet, do NOT use a hammer), it will be enough to get the switch to pop back up. Otherwise, the coolant reservoir may need to be replaced for the light to go out.
