If no oil pressure is indicated, STOP the engine. If maximum coolant temperature is exceeded, STOP the engine. Engine damage can result.
Engine Oil Pressure - The oil pressure should be greatest after a cold engine is started. The typical engine oil pressure with SAE10W40 is 350 to 450 kPa (50 to 65 psi) at rated rpm.A lower oil pressure is normal at low idle. If the engine speed and load are stable and the gauge reading changes, perform the following procedure:
Remove the load.
Stop the engine.
Check and maintain the oil level.
Jacket Water Coolant Temperature - Typical temperature range is 82° to 94°C (179.6° to 169.2°F). This temperature range will vary according to engine load and the ambient temperature.A 100 kPa (14.5 psi) radiator cap must be installed on the cooling system. The maximum temperature for the cooling system is 108° C (226.4° F). This temperature is measured at the outlet for the water temperature regulator. The engine coolant temperature is monitored by the engine sensors and the engine ECM. This programming cannot be altered. Derates can occur if the maximum engine coolant temperature is exceeded.If the engine is operating above the normal range, reduce the engine load. If high coolant temperatures are a frequent event, perform the following procedures:
Reduce the load on the engine.
Determine if the engine must be shut down immediately or if the engine can be cooled by reducing the load.
Inspect the cooling system for leaks. If necessary, consult your Caterpillar dealer for assistance.
Tachometer - This gauge indicates engine speed (rpm). When the throttle control lever is moved to the full throttle position without load, the engine is running at high idle. The engine is running at the full load rpm when the throttle control lever is at the full throttle position with maximum rated load.
To help prevent engine damage, never exceed the high idle rpm. Overspeeding can result in serious damage to the engine. Operation at speeds exceeding high idle rpm should be kept to a minimum.
Ammeter - This gauge indicates the amount of charge or discharge in the battery charging circuit. Operation of the indicator should be to the "+" side of "0" (zero).
Fuel Level - This gauge indicates the fuel level in the fuel tank. The fuel level gauge operates when the "START/STOP" switch is in the "on" position.
Service Hour Meter - The gauge indicates total operating hours of the engine.Indicator Lamps
Shutdown lamp
Warning lamp
Low oil pressure lamp
Wait to start lamp (Glow plug warning lamp)For information, refer to this manual, "Monitoring System (Table for the Indicator Lamps)" for the sequence of operation of the shutdown lamp and the warning lamp.The function of the wait to start lamp is automatically controlled at engine start-up.The function of the low oil pressure lamp is controlled by the engine ECM. If low oil pressure is detected, the lamp will be illuminated. The reason for the illumination of the low-pressure lamp should be investigated immediately.The glow plug warning lamp will flash to show that the engine is being held at low speed. This function will be performed at engine starting and the duration will depend on ambient temperature and engine temperature.The lamps will illuminate for 2 seconds to check that the lamps are functioning when the keyswitch is turned to the ON position. If any of the lamps stay illuminated, or a lamp fails to be illuminated the reason should be investigated immediately.Aftertreatment Lamps and gauges
All applications will require the following lamps and gauges:
Emission malfunction lamp
Action indicator lamp
Gauge for Diesel Exhaust Fluid (DEF)
Low warning lamp for DEF
Wait to disconnect lamp (optional)The wait to disconnect lamp will be illuminated during engine operation and will be extinguished approximately 2 minutes after the engine has stopped. Do not disconnect the battery disconnect switch during the period the lamp is illuminated. The diesel exhaust fluid system will be purged during this time. Also, during the 2 minutes the engine electronic control module is active storing information from the engine and aftertreatment sensors.Note: The wait to disconnect lamp will not be checked at key on.
