Coolant sensor is shot. Replace with new one.
AnswerThe reed switch may be stuck. My 98 Grand Am coolant tank ran dry last week when my lower intake manifold gasket started to leak. Fixed the leak and refilled the tank only to see the coolant light still on. Tapped the switch/sensor on the bottom OS the tank with a rubber mallet so the magnetic float could loosen up and float back up. Sure enough, turned on the ignition and light was out.When the low coolant warning light comes on and the car has enough coolant, it usually means there is a problem with the coolant level sensor system. The sensor may need to be replaced.
Low coolant level.
when u have low coolant
Low coolant
Low coolant? Bad sensor?
its a dance party
change your thermostat.
Perhaps a defective sensor?
Check to coolant level in the coolant recovery tank and radiator when engine is cold
low antifreeze , or faulty coolant sensor .
I'm having to guess it's the low coolant light? Possible coolant switch in the overflow bottle is dirty or defective., Is it low on coolant? Possible wiring issue to sensor.
have you filled up your coolant if so its the computer chip unplung your battey cable for fifteen minutes
