Well the code is another problem. Remove the coolant overflow bottle and clean it out good with hot water and some soap you should notice that there is a sensor in side of it and on some older cars over time they get gumed up and wont read right try this first if it wont work you will have to buy a new one.

1998 buick century low coolant light keeps flashing after I filled overflow container-radiator is full

Change the low coolant sensor. It is located on the radiator. It might be a good idea to get the radiator flushed too.

My low coolant light flashes on and off then it will stay on.I have checked my coolant level it is good what could be the problem? 1999 Buick regal

Make sure you are checking the coolant level in the radiator as well as in the overflow tank. The sensor is located in the radiator, so if the level in the overflow tank is good, it could still be low in the radiator.

I have a 1992 Buick Regal, and my coolant light was on the other day, and after I added some fluid to the overflow tank, it is still on. How do I add the coolant to the radiator itself? because I think...

3.1 liter?

If so the level sensor is in the reservoir. Sometimes the level gets stuck if the coolant gets low. Some gentle whacking of the reservoir with a rubber mallet is usually enough to get the light to turn out.

3.8 liter?

When the car is cold remove the radiator cap on the passenger side of the radiator. Add coolant until full.

My low coolant light is flickering on and off. I flushed the system today. No other symptoms. no overheating or leaks. this is on a 1995 Buick Regal Custom V6.

It could be that the low coolant sensor is just dirty. You should be able to follow a wire to the top part of your radiator, to the sensor, or it might be in the overflow tank, take it out and clean it, and see if that will do it, if not, replace it.

Low Coolant light flashing on 1996 Buick Regal 3.8

The low coolant sensor should be located in the passenger side radiator tank, You need to take it out and clean the sludge off of it for it to work right. Or you can just unplug it and forget about it, the light will go out and it won't cause any problems.
