2001 Buick Century Question: Sensor light for coolant levels
The coolant reservoir sensor may just be stuck. I would try flushing out the coolant reserve tank to free up the sensor, if that does not work, you can get a new sensor from GM for about $50. - dandd
I changed out the waterpump but now the "low coolant" light comes on at starting and will not go off til run awhile then shut off and restarted. Coolant level is right up in rad and overflow conta...
If it is a sensor where is it located on the cooling system
Coolant light comes on quite often but the radiator is full. Also the radiator has slime around the neck. I thought i WOULD TRY and do a flush and see it that helps. The car never runs hot.
