What to do if coolant leaks at charge-air cooler in MTU Engine?
If you notice coolant leaks at the charge-air cooler of your MTU Engine, it indicates that the intercooler is leaky, resulting in major coolant discharge. To fix this, replace the intercooler.
What to do if my MTU 12V4000M73 has black exhaust gas?
Black exhaust gas from the engine can be caused by overload, a clogged air filter, or a defective injector. You should reduce the load and check the signal ring position of the service indicator. Also, replace the air filter.
Why MTU 12V4000M73 does not reach rated speed?
If the engine isn't reaching its rated speed, possible causes include engine overload, a clogged air filter, a clogged fuel prefilter, a clogged easy-change fuel filter, faulty engine cabling or a defective injector. Try reducing the load, checking the service indicator's signal ring position, replacing the air filter, draining water and contaminants from the fuel prefilter, and replacing the filter element.
Why is there white smoke in MTU Engine room?
If you observe white smoke in the engine room of your MTU Engine, it is likely due to the initial start-up. To resolve this, wait, maximize ventilation, and leave the area.
What to do if MTU Engine shows pre-alarm?
If the differential pressure exceeds 1.3 bar in your MTU Engine, it triggers a pre-alarm. To resolve this, replace the coalescer filter element.
Why urea solution escapes from SCR system repeatedly in MTU Engine room?
If urea solution repeatedly escapes from the SCR system in the engine room of your MTU Engine, it could be due to urea solution efflorescence or leaks/cracks in the urea solution system. To resolve this, check the peripheral equipment and replace as necessary, and check for leakage and replace components as necessary.
What causes MTU Engine to fire unevenly?
If your MTU Engine is firing unevenly, it could be due to faulty engine wiring, a faulty injector, or a faulty Engine Control Unit. To address this, check the engine wiring, replace the injector, or replace the Engine Control Unit. If problems persist, contact Service.
Why MTU Engine does not reach nominal speed?
If your MTU Engine does not reach nominal speed, it could be due to excessive load, a clogged air filter, a clogged fuel prefilter, a clogged easy-change fuel filter, faulty engine wiring, a faulty injector, or excessive exhaust back pressure. To address this, reduce the load, check the signal ring position of the service indicator, replace the air filter, drain the fuel prefilter, replace the fuel filter element, check the engine wiring, replace the injector, or check the SCR system. If problems persist, contact Service.
Why are there white crystals on plug connections or urea solution system of MTU Engine?
If you see white crystals on plug connections or the urea solution system of your MTU Engine, it indicates leaks or cracks in the urea solution system. To resolve this, check for leakage and replace components as necessary.
What to do if MTU 12V4000M73 fires unevenly?
Uneven firing can be caused by faulty engine cabling, a defective injector, or a faulty Engine Control Unit. Check the engine cabling and replace the injector. Contact Service.
