I have two bonnes that both display low coolant. The coolant is not low in either of them.Anybody else dealt with this issue? And is there a solution to make the warning go away?

Did you check the coolant level in both the overflow tank, and the radiator?

Yes, the 93 has a warning that comes on right away and stays on,the 90 after warming and driving it for a while it goes away but still come on every morning only when it frosty out.

Could be your low coolant sensor had gone bad. Not sure where yours is.
What make and model do you have...year

to better help you, could you please update your siggy to reflect your cars info

Thanks.

That'* what I was thinking as well. But I can't remember where it'* located.

Ok did the siggy thing.Thanks

Here'* what I foundSometimes if the jar gets low on coolant, an air pocket will develop on the sensor which could be in the plastic reservoir or the radiator tank. Sometimes you can tap lightly on the sensor to dislodge the air bubbles and the light will go out.

And be sure the coolant is filled to the top of the radiator and the coolant bottle is filled to the proper level.
