OPERATION
Engine Temperature
The normal engine operating temperature range is
180–225°F (82–107°C).
If the temperature exceeds 230°F (110°C), an ongoing
intermittent tone will be heard and the cab display module
(CDM) (A) w ill flash “ENGINE TEMP”. Stop the engine

the CDM (A) will return to normal when the temperature
drops below 225°F (107°C).
