AIR CLEANER GP 6I2399 - Caterpillar

Illustration 1 g00665205
Engine Coolant Temperature (1) - This gauge indicates the engine coolant temperature of the tractor. Also, the gauge can show the engine coolant temperature of the scraper. When the Caterpillar monitoring system is operating in the tractor mode, the Caterpillar monitoring system will display the information for the tractor engine. When the Caterpillar monitoring system is in the scraper mode, the Caterpillar monitoring system will display the information for the scraper engine. When there is a problem with the engine coolant temperature of the tractor or scraper, the gauge will show data for the system that is experiencing trouble. When the temperature is above 111° (225°), the needle will be in the red zone. If the needle is in the red zone, stop the engine immediately and investigate the cause of the problem.

Engine Coolant Temperature Gauge    
Minimum Displayed Value    
45 °C (113.0 °F)    
Midpoint Value    
84 °C (183.2 °F)    
Red Zone Value    
111 °C (224.6 °F)    
Maximum Displayed Value    
122 °C (251.6 °F)    Do not operate the machine until the cause of the problem has been corrected.
Torque Converter Oil Temperature (2) - This gauge indicates the torque converter oil temperature of the tractor. Also, the gauge can show the torque converter oil temperature of the scraper. When the Caterpillar monitoring system is operating in the tractor mode, the Caterpillar monitoring system will display the information for the torque converter for the tractor. When the Caterpillar monitoring system is in the scraper mode, the Caterpillar monitoring system will display the information for the torque converter for the scraper. When there is a problem with the torque converter oil temperature of the tractor or the scraper, the gauge will show data for the system that is experiencing trouble. When the temperature is above 129 °C (264 °F), the needle will be in the red zone. If the needle is in the red zone, reduce the load on the machine. If the needle stays in the red zone, stop the machine and investigate the cause of the problem.

Air Supply Pressure (3) - This gauge indicates the air pressure in the air tanks. When the Caterpillar monitoring system is operating in the tractor mode, the Caterpillar monitoring system will display the information for the tractor air reservoir. When the Caterpillar monitoring system is in the scraper mode, the Caterpillar monitoring system will display the information for the scraper air reservoir. If the air pressure drops below 517
