How to fix Detroit Diesel Engine cooling system that is losing coolant?
If your Detroit Diesel Engine's cooling system is losing coolant, look for external coolant leaks and repair the leaking component. Replace the radiator cap if it is leaking. Have an authorized dealer replace the air compressor head or cylinder head gasket if they are damaged.
Why Detroit Diesel MBE4000 Engine exhaust is black?
If the exhaust from your Detroit Diesel Engine is black, check the air filter and intake air system for clogs, and clean the system and replace the air filter if necessary. Have an authorized dealer check the exhaust brake valve for malfunctions. Check that the intake air preheater is not staying on all the time. Ensure the valves are properly adjusted by checking the valve lash. For damage to the fuel system, a damaged charge-air temperature sensor, or internal engine damage, bring the vehicle to an authorized dealer for service.
What to do if Detroit Diesel MBE4000 Engine coolant temperature is above normal?
If the coolant temperature of your Detroit Diesel Engine is above normal, check for coolant leaks and repair as needed. Tighten or replace the poly-V belt if it is loose. If the radiator is damaged or dirty, clean or replace it. Have an authorized dealer replace the coolant pump or thermostat if they are damaged. For issues with the coolant temperature gauge or sensor, or if the fan is not operating properly, bring the vehicle to an authorized dealer for service.
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.
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.
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.
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 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.
