Advantages:
Coolant level sensing can reduce the chance of engine
damage caused by loss of coolant.
Disadvantages:
Programming this parameter to Yes when there is no
coolant level sensor installed can cause false logging of
coolant level faults.
Recommendations:
✔ Cat recommends programming to Yes if the OEM
has installed a Coolant Level Sensor.
