INJECTOR GP-FUEL 3264756 - Caterpillar

Your engine may not have the same gauges or all of the gauges that are described. For more information about the gauge package, see the literature that is provided by the OEM.Gauges provide indications of engine performance. Ensure that the gauges are in good working order. Determine the normal operating range by observing the gauges over a period of time.Noticeable changes in gauge readings indicate potential gauge or engine problems. Problems may also be indicated by gauge readings that change even if the readings are within specifications. Determine the cause of any significant change in the readings. Then, correct any cause of any significant change in the readings. Consult your Caterpillar dealer for assistance.Caterpillar requires one lamp in addition to the gauge package that is normally provided. The "DIAGNOSTIC" lamp is yellow or amber. The "DIAGNOSTIC" lamp will communicate the status of the engine's electronic system and the status of the Diesel Particulate Filter (DPF). The optional red "" lamp is also available. The red "" lamp warns the operator of engine problems.The following conditions are some examples of the engine problems:
Low oil pressure
High coolant temperature
Low coolant level
High inlet air temperature
High exhaust back pressure
Engine Oil Pressure - Typical oil pressure for an engine at rated speed with SAE 10W30 or with SAE 15W40 is 240 to 480 kPa (35 to 70 psi). A lower oil pressure is normal at low idle. If the load is stable and the gauge reading changes, perform the following procedure:
Remove the load.
Reduce engine speed to low idle.
Check the oil level. Maintain the oil level at the proper amount.The "DIAGNOSTIC" lamp will turn on if the oil pressure drops below 35 kPa (5 psi) at low idle rpm. The diagnostic code will be logged in the Engine Control Module (ECM).
Engine Oil Temperature - This gauge indicates the engine oil temperature. An oil temperature that is higher than normal indicates a heat problem in the lubrication system and/or the cooling system. This problem can damage the cylinder heads, the cylinder liners, the pistons, and the crankshaft bearings.
Jacket Water Coolant Temperature - Typical temperature range is 88 to 102 °C (190 to 215 °F). The maximum allowable temperature with the pressurized cooling system is 105 °C (220 °F). Higher temperatures may occur under certain conditions. The water temperature reading may vary according to load. The reading should never exceed the boiling point for the pressurized system that is being used. If the engine is operating above the normal range and steam becomes apparent, perform the following procedure:
Reduce the load and the engine rpm.
Inspect the cooling system for leaks.
Determine if the engine must be shut down immediately or if the engine can be cooled by reducing the load.
Tachometer - This gauge indicates engine speed. 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
