Perform the required daily maintenance and other periodic maintenance before starting the engine. Inspect the engine room. This inspection can help prevent major repairs later. See this Operation and Maintenance Manual (Maintenance Section), "Maintenance Interval Schedule".Walk-Around Inspection
Inspect for leaks. Clean up any fluid leaks (coolant, lube, fuel, or DEF). If leaking is observed, find the source and repair the leak. If leaking is suspected, check the fluid levels more often than recommended until the leak is repaired.
To obtain maximum service life for your engine, make a thorough inspection before starting the engine. Make a walk-around inspection of the installation. Look for items such as oil or coolant leaks, loose bolts, and trash buildup. Remove any trash. Arrange for repairs, as needed.
The guards must be in the proper place. Repair damaged guards or replace missing guards.
Ensure that the areas around the rotating parts are clear.
Air Inlet System
Ensure that the air inlet piping and the air filters are in place.
Ensure that all clamps and connections are secure.Cooling System
Inspect the cooling system for leaks or loose connections.
Inspect the cooling system hoses for cracks and for loose clamps.
Inspect the water pumps for evidence of leaks.
Check the coolant level. Add coolant, if necessary. For information on the proper coolant to use, see this Operation and Maintenance Manual, "Refill Capacities and Recommendations" (Maintenance Section).Driven Equipment
Note: If the engine is equipped with a system for external support, prepare the system before starting the engine. Perform all prestart checks for the control system.
If necessary, check the oil levels of the driven equipment. Perform any maintenance that is required for the driven equipment. See the literature that is provided by the OEM of the locomotive or the driven equipment.
If the engine is equipped with a clutch, ensure that the clutch is disengaged.Electrical System
Inspect the wiring for the following conditions:
Loose connections
Wiring that is worn or frayedInspect the alternator belt for cracks and for deterioration.Ensure that the grounds are secure.Fuel System
All valves in the fuel return line must be open before and during engine operation to help prevent high fuel pressure. High fuel pressure may cause filter housing failure or other damage.
Inspect the fuel lines for loose fittings and leaks. Ensure that the fuel lines are properly clamped.
Ensure that fuel is supplied to the engine.If the engine has not been started for several weeks, fuel may have drained from the fuel system. Air may have entered the filter housing. Also, when fuel filters have been replaced, some air space will be left in the filter housing. In these instances, prime the fuel system. For information on priming the fuel system, see this Operation and Maintenance Manual, "Fuel System-Prime" topic (Maintenance Section).Lubrication System

Oil level gauge
(1) "ADD" mark
(2) "FULL" mark
Excessive engine oil will increase oil consumption and result in excessive deposits in the combustion chamber. Do not overfill the engine with oil.
Note: Ensure that the engine has been stopped for a minimum of 45 minutes to prevent overfilling.
Check the engine crankcase oil level. Maintain the oil level between the "ADD" and "FULL" marks on the "ENGINE STOPPED" side of the oil level gauge. For information on the proper oil to use, see this Operation and Maintenance Manual, "Refill Capacities and Recommendations" (Maintenance Section).
Check for leaks at the following components: crankshaft seals, crankcase, oil filters, oil gallery plugs, sensors, and valve covers.
Inspect the tubes, tee pieces, and clamps on the crankcase breathers.Starting System
Inspect the instrument panel and the control panel for good condition.
Reset the shutoff and alarm components.Electric Starting Motor
Disconnect any battery chargers that are not protected against the high current drain that is created when the electric starting motor engages.Inspect the wiring, the electrical cables, and the battery for the following conditions:
Loose connections
Wires that are worn or frayed
CorrosionSCR System Inspection
SCR System
Ensure that the area around the SCR system is clear of flammable materials.
Inspect access panels.
Inspect DEF lance.
Inspect bulkhead fittings.
Ensure urea lines and air lines.
Inspect sensors.
Inspect wiring harness.Dosing Cabinet
Ensure that filter screens are in place.
Ensure that all lines are secure.
Check for fluid leaks. Ensure all fluids that have leaked are cleaned up and properly disposed of.
Check A/C power supply.
Check D/C power supply.
