Add Coolant light keeps coming on..
Like the title says, that damn light keeps coming on, a couple of days ago i turned on the car and took off the radiator cap to add more coolant but then collant level only went downan inch, the reservoir was completely full also. I waited about 15 minutes while revving up to 2000 rpms occassionaly. The temp gauge has also never gone above 210 since the light started coming on 3 weeks ago. Anyone have any advice? Thanks

Mine has not freaked out, yet.
I pulled the sensor when I was doing a flush. The sensor had all kinds of crusty crap in it. I just cleaned it out. From what I have heard on here, that helps also.

Yeah I figured it was a sensor since i have kept an eye on the temp gauge mainly and it has acted normal, I'll probably just unplug it or try cleaning it for now. thanks for the help.

Sensor is located a few inches below the radiator cap. GM PN is 10096163 and dealership list is $65 so I'd look elsewhere. My car didn't come with one, not sure what year GM took them off the F body.

I want to try. when I bought my car there was crusty stuff all in on the coolant level sitck and I bet that is the culprit. I flushed the coolant but I bet some good cleaning would do wonders.

My bad sensor came out perfectly clean. Here's an interesting article: http://www.wellsmfgcorp.com/pdf/Counterpoint2_2.pdf It does mention that sludge can cause coolant sensors to mis-read, however I think mine was a thermal failure.
I'm assuming our level sensors are probably just a simple on/off temperature sensor set to a very very low temperature? If so, that would be in line with how mine failed. It would start to work when the engine reached a certain temperature. Over time, that "happy" temperature rose to a higher and higher point until it wouldn't work at all.
