My coolant level sensor is dead, too. Just like others have done, I disconnected it and I check the level manually.

i replaced my sensor does the same damn thing , i seriously doubt i got a bad replacemnet sensor but i have no clue why my light comes on , only when it warms up a bit checked level cold checked it hot always good//
I had the Low Coolant Level light come on today and upon inspection , the coolant level was fine. I cleaned off the metal rod on the sensor with a Q-tip and the light turned off. Lucky me. Thanks to those who posted about this quick fix.

I used C.L.R. (Calcium Lime Rust) cleaner on my sensor, worked great. Bought car used, light came on soon after, it's been off for over 2 years now. I believe there was a wire retainer holding the sensor in?
Mine came on last week. It is not "on all the time." What I mean to say is, after I start the car it takes about 5 to 10 minutes before it comes on. IS that the same problem the rest of you are having, or is your light on from the moment you start your car?
Thanks. Bob

I fixed mine, wasnt the sensor , rarely is from what i hear I got a huge funnel and placed in radiator started car and let it get hot and a couple heat cycles (fans kicking in ) and made sure it was topped off if any air trapped in system makes that sensor trigger , but mine would come on after 10 mins or so since i did that trick with big funnel to let it boil into have had zero issues

Mine comes on at startup when the car is cold. If I get to a stoplight when I am up to temp and turn the car off and on, the light doesn't come on. Also, if I drive on the freeway, with the light off, it will suddenly turn on after about 50 minutes of driving. GM could have designed this headache better.

1) removed cap and placed large funnel in radiator
2) started car and allowed to hear up
3) topped off level in radiator with car running
4) removed funnel and replaced cap
That's it?
