Why would a low coolant level light stay on on a 1998 buick skylark?

There can be two reasons for this problem:
1. The magnetic reed switch has gone bad. (this part goes up from the connector at the bottom of the tank into a column molded into the plastic tank.)
2. The tank interior has gotten clogged with rust or debris and the magnetic float isn't moving with the level.
Take the reed switch out and test it with an ohmmeter. The ohms should go from 0 to infinite as a magnet is moved past the switch.
