I have a slow leak and about once a week the low coolant light would come on. I would add antifreeze-would only take about a glassful to fill it up- and then light would go off. But couple of days ago it started flashing off and on constantly, even if its full. Sensor going out maybe?

it could be the sensor. first find out if you have a loose wire, a short, or some bare wire. then find out what kind of sensors you have. their may be more than one on the coolant system. one will be a temp sending unit screwed into the block, usually on the side. the other may be attached to the water/thermostat cover. it should be near the top of the block and have the upper radiator hose connected to it. the sensor will be screwed into it and have wire and connector attached to it. remove the hose, and the thermostat cover from the block and check it for corrosion or build-up on the sensor. if it has a corroded or deposit build-up, replace the whole thing as well as the thermostat since you already have it uncovered.

Maybe.
Could be that it lighted up so many times it is wearing out or that the float is stuck. Drive it a few days and see if it goes out. If not, you could unplug the wire going to the float sensor but then you wouldnt have a warning when it gets low again....

Could be the sensor or it could be an air bubble trapped around the sensor.

you have an internal leak somewhere or you just might need to add coolant.If none of these and u have a computerized vehicle,take it to a shop and have it reset.

you need to fix the leak, fill the radiator and you will have no more problems

sounds like the temperature sending unit is acting up.
