Low coolant alarm going off

Inside the plastic surge tank is a ring with a float. The low coolant sensor sits in a pocket not touching the coolant it reads the ring. They go bad and get stuck on the bottom so the sensor thinks it is low on water. Can't get to it have to replace the plastic surge tank. Just had to do this on my 2010 Granite that I drive daily. It would also derate the motor. Very annoying.

 Cheers.

Not sure about the max on our kenworths all you have to do is pull out the plug and the light will go off I don’t recommend it but it will get you through until you have time to fix it .. Bob
