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? 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
Assuming your coolant level isn't actually low, it's most likely a bad sensor
Coolant level low or level sensor malfunction.Coolant level low or level sensor malfunction.
If it's overheating, it cold be thermostat, radiator or possibly other problems. If it's not overheating it could be the coolant level sensor.
Sometimes the sensor will go bad but try removing it first and cleaning the inside of the sensor. They sometimes get filled with crud from not flushing or old coolant, etc. It's located in the tank on the passenger side so removing the battery first helps.
The engine is overheating. The check engine light is not on because you have no problem with the emissions system which this light monitors.
Factory manual says that the light should go out on its own after three cycles of warm-up and cool down. If it doesn't then check the coolant level when it's cold and fill to the "full cold" mark on the coolant recovery tank.
it sounds like your primary coolant fan has quit and when you turn your A/C on it causes your secondary coolant fan to turn on and then cools the coolant in your radiator!
Mine went nut. After I filled up the coolant reservoir, the D light stopped flashing. Good luck!!
The coolant light should be going out when the system is filled. The sensor itself or the float system is probably bad.
There is a sensor in the side of the radiator that is most likely defective.
Add coolant to the reservoir. If the low coolant light still stays on, replace the low coolant sensor.
Reservoir light? You mean low coolant light. Low coolant level means the reservoir is low of coolant.
Low on coolant? defective sensor should be located on back side of radiator approx. 1/3 down from top
