How to remove/replace 86 Low Coolant Sensor?
Stock 1986 Corvette Coupe: My radiator is confirmed absolutely full but the "coolant low" light comes on intermittently, around every 10-15 mins. I found this thread which helped clean the sensor connector:
http://forums.corvetteforum.com/c4-t...-light-on.html
But if the light persists how do I remove the sensor from the radiator to clean it and put it back? I tried to give it a twist but it only moved a millimeter or two, is there a specific technique required? Will coolant come flowing out if/when I am able to remove it?
Any help/advice would be appreciated,

You need to burp your radiator. You have trapped air pockets in your cooling system.
I use my ramps and put the front of the vette on the ramps. This makes my radiator a higher water level. With car at 180 degrees, I give it gas to about 1500 rpm's with the cap off. I fill the radiator then. Before letting rpm's drop put cap back on.

Forget about cleaning it, and replace it.

Finally, you need to burp your cooling system to purge the trapped air out from under the thermostat. See attached write-up.
