l\coolant light

[ppost]

I need advice The low coolant light goes on even when coolant is full

Is the coolant tank and sensor tube covered with rust scum?

The sensor is in the overflow cap. They fail regularly. If the bottle is full, then no need to worry about the actual cooling system. If the light is on, but the bottle full, just unplug the sensor. Try cleaning it, otherwise time to replace it.

Mine had enough rust scum to keep the floaty thing from moving, cleaned it and has worked ever since

I have replaced the tank and unit the is inside the tank. I know the tanks full it's just very annoying. I have unplugged it.
