Default Low coolant loght on @ DIC

My driver info center was saying low coolant yesterday while the radiator was full.
I added 1/2 bottle of water pump / anti rust lube and it went out.
Could it have been the switch or float sticking???

Apparently the one on my Bonneville has gone on a few times during the winter, I couldn't tell you first hand since it is my fiancÚ that drives it all the time. Seems that once it warms up it goes out. I am pretty sure that I have already changed the sensor. As long as your overflow bottle is full and your rad is full, you should be fine.

Default light

Still getting the light.
If I press the DIC button again it goes out after going through the checks?

Mine would do that also. Just something it does when you reset, I believe it resets some of the errors every time or so. When I was losing coolant [damn coolant leak], my warning light would come on once every three times or so.

Mine was doing the exact same thing.... esp on cold days (below 10c)..... replace the sensor and you should be fine.

I've heard that the sensors could get really dirty. Like calcium scales and rust and stuff forming on the sensors that could cause them to give a false reading??? Maybe just a simple pull and inspect and check the wiring connection too?

Default sensor

Thanks for the input.
I tried cleaning the connector so I guess the next thing would be to take it out and clean the tip. I hate to drain the radiator.
Is it hard to get out of the radiator?
I should have a warm day this week.
