Do you know why my coolant low light comes on? The fluid is full. It does not come on all the time.

This is due to a faulty sensor most likely. I am attaching the process on how to replace this sensor. Let's run through this and let us know what happens after you replace the sensor.

Basically if the coolant is not low in the bottle but the low light comes on then the sensor is faulty. So it is in the bottom of the bottle and needs to be replaced. Thanks
