Why Detroit Diesel MBE4000 Engine exhaust is blue?
If the exhaust from your Detroit Diesel Engine is blue, adjust the oil level if it is too high, and then have it checked by an authorized dealer. Have an authorized dealer replace the turbocharger if it's leaking oil, replace the valve stem seals if they are loose or damaged, or replace the piston rings if they are worn.
Why Detroit Diesel Engine starts only after cranking for a long time?
If your Detroit Diesel Engine starts only after cranking for a long time, the fuel tank may be low or empty, so add fuel and bleed the fuel system if necessary. Check the fuel lines for leaks and repair them if needed. Replace the fuel filter element if it's clogged. If the fuel line, pre-filter, or screen in the fuel tank is blocked, clean and bleed the system, and have the fuel lines and filters checked by an authorized dealer. Ensure the camshaft TDC sensor and crank angle position sensor are correctly adjusted by pushing both sensors into their holes as far as they will go, and if that doesn't work, take the vehicle to an authorized dealer. Other fuel system problems or damaged sensors will also require dealer assistance.
Why Detroit Diesel Engine starts, but dies?
If your Detroit Diesel Engine starts but then dies, the fuel tank may be low or empty, so add fuel and bleed the fuel system if necessary. Replace the fuel filter element if it's clogged. If the fuel line, pre-filter, or screen in the fuel tank is blocked, clean and bleed the system, and have the fuel lines and filters checked by an authorized dealer. Ensure the camshaft TDC sensor and crank angle position sensor are correctly adjusted by pushing both sensors into their holes as far as they will go, and if that doesn't work, take the vehicle to an authorized dealer. Malfunctioning constant-throttle valves or other fuel system problems will also require dealer assistance.
Why Detroit Diesel MBE4000 Engine will not crank?
If your Detroit Diesel Engine won't crank, it might be due to several reasons. The batteries could be weak or damaged, requiring a test and possible replacement. The ignition switch might be faulty and need replacement. Damaged or corroded battery cables should be replaced. A damaged or worn starter should be replaced by an authorized dealer. If the clutch or transmission is damaged, or if there's internal engine damage, take the vehicle to an authorized dealer for service.
How to fix Detroit Diesel MBE4000 that turns over slowly?
If your Detroit Diesel Engine turns over slowly, the batteries may be damaged or weak, requiring a test and possibly replacement. The ignition switch might be damaged and need replacement. Damaged or corroded battery cables should be replaced. A damaged or worn starter should be replaced by an authorized dealer. Also, ensure that the engine oil and transmission fluid meet the correct specifications; if not, change them to the correct type.
What to do if Detroit Diesel MBE4000 performs poorly, and does not develop full power?
If your Detroit Diesel Engine performs poorly and doesn't develop full power, check the air filter and intake air system for clogs, cleaning the system and replacing the air filter if necessary. Have an authorized dealer check the exhaust brake valve for malfunctions. Replace the fuel filter element if it's clogged. For other fuel system problems, or issues with the coolant, fuel, or engine oil temperature sensors, or the charge-air temperature sensor, bring the vehicle to an authorized dealer for service. Ensure the valves are properly adjusted by checking the valve lash. Internal engine damage or problems with the PLD or VCU control unit also require dealer assistance.
Why Detroit Diesel MBE4000 brake performance is poor?
If your Detroit Diesel Engine brake performance is poor, replace the switch if the engine brake control switch is damaged. Have an authorized dealer check the operation of the valve if the exhaust brake is not operating properly. Bring the vehicle to an authorized dealer for service if the constant-throttle valves are malfunctioning or if components of the PLD or VCU control unit are damaged.
What to do if there is coolant in the Detroit Diesel MBE4000 Engine oil?
If there is coolant in the engine oil of your Detroit Diesel Engine, have an authorized dealer replace the head gasket if it is damaged, or replace the heat exchanger if the oil/water heat exchanger is leaking. For an internal coolant leak, bring the vehicle to an authorized dealer for service.
What to do if Detroit Diesel MBE4000 fan doesn't work?
If your Detroit Diesel Engine fan isn't working, replace the fan hub if it's damaged. Repair the fan wiring if it's damaged. Have an authorized dealer reprogram the control unit if the parameter settings in the PLD or VCU control unit are incorrect.
What to do if Detroit Diesel Engine oil pressure is low?
If your Detroit Diesel Engine oil pressure is low, bring the vehicle to an authorized dealer for service if the oil pressure gauge or sensor is not reading correctly, or if there is fuel in the oil. Replace the filter element if the oil filter is clogged. Replace the bypass valve if the oil filter bypass valve is damaged. Have an authorized dealer replace the oil pump if the oil pump or relief valve is damaged.
