The coolant light runs off a switch in the passenger side of the radiator. This switch corrodes quickly and turns on the low coolant light. Replace the switch. Runs about $60. You'll find that the probe on the switch is all corroded. Worked for me.........

Could be the Engine temp sensor is corroded as well. The alluminum block engines cause the temperature and level sensors to corrode rapidly.
