Hello, I found my 2012 Cruze to be extremely low on coolant. However, the instrument cluster never indicated that my coolant was low. I wonder if my coolant level sensor is broken.
What level of coolant in the tank will cause the coolant low message is triggered? Is there a way I can manually test my coolant level sensor to ensure that it's working? Can I just replace the sensor or must I get a whole new tank?
The attached photo shows the level of coolant in my tank which did not cause a low coolant message. Thanks for your input.
