I had a problem with my coolant leaking.Corrected that problem but the Low Coolant light still comes on after the car is started and runs for a minute. What else needs to be done.

Could be your low coolant sensor is bad, or you could have air in the cooling system. If air is in the sysytem it will need to be purged. Good Luck to you
Thank you ProChevy can you tell me where the Sensor is located. I replaced the Radiator Coolant Sensor and we have bled the hose to try and get the air out.
