318 Low Coolant Warning Light On Always

Coolant light comes on with ignition and stays on. Coolant is at correct level and the temp gauge reads normal when driving. Any ideas?

There you go. The magnet on the bottom of the float dropped off.

Test this theory by removing the level sensor and keep it plugged in outside of tank. The light should go off. If so, you live with it and monitor frequently, or you get a new tank...an OE tank...and refund on old one!
