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.
What to do if MTU 12V4000M73 has pump fault?
A pump fault occurs if the drive motor's overload protection is triggered due to excessive current, such as from a blockage or dry-running. The solution is to reset the motor protection relay.
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.
What causes exhaust back pressure to be too high in MTU Engine?
If the exhaust back pressure is too high in your MTU Engine, it could be due to the SCR substrate being clogged with soot or ash. To resolve this, briefly connect the engine load to blow off SCR substrates. If the exhaust back pressure does not fall, contact Service.
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.
What to do if the MTU 12V4000M73 Engine coolant escapes at intercooler?
If engine coolant is escaping at the intercooler, it indicates a leaky intercooler with major coolant discharge. Replace the intercooler.
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.
