KIT-GASKET 1648900 - 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 from 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 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.Electronically controlled engines require 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 electronic system for the engine. An optional "Warning" lamp is available. This red "Warning" lamp warns the operator of engine problems.The following conditions are some examples of the problems:
Low oil pressure
High coolant temperature
Low coolant level
High inlet air temperature
Engine Oil Pressure - Typical oil pressure for an engine at rated speed with SAE 10W30 or with SAE 15W40 is 207 to 310 kPa (30 to 45 psi) for the C-10 and the C-12. Typical oil pressure for an engine at rated speed with SAE 10W30 or with SAE 15W40 is 276 to 606 kPa (40 to 88 psi) for the 3406E, C-15, C-16and C-18. A higher oil pressure is normal with cold oil when the engine is started. 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 87 to 98° C (189 to 208° F). The maximum allowable temperature with the pressurized cooling system is 102° C (216° F) for the C-10 and the C-12. The maximum allowable temperature with the pressurized cooling system is 107° C (225° F) for the 3406E, C-15 C-16, and C-18. 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
