what is the trick(code) to shut off the low coolant light on a 2000 century buick/
The light is connected to a sensor in the coolant tank under the hood, if the tank is full the light should be out, if it is full and the light is still on then the sensor is stuck closed, to fix it properly you will have to replace the sensor, if you just want to get by for a time just unplug the sensor connector right at the tank, but keep watch on the coolant level, you don't want to loose an engine due to no coolant.
