What to do if the MTU 16V 2000 G23 does not turn when starter is actuated?
- C
  Christopher WilsonAug 16, 2025
  If the MTU Engine doesn't turn when you actuate the starter, there are several potential causes. It could be due to a low or defective battery, in which case you should charge or replace it. Defective cable connections can also be the reason, so check if they are properly secured. Issues with the engine wiring or starter itself could be the problem, so check the cable connections. Also, make sure that the assemblies or connectors are seated correctly by performing a visual inspection, and check for loose plug-in connections. If the running gear is blocked, preventing manual barring of the engine, it is recommended to contact Service.

Why MTU 16V 2000 G23 Engine does not reach nominal speed?
- R
  richardmurphyAug 19, 2025
  The MTU Engine might not reach its nominal speed due to several reasons. A clogged fuel prefilter or fuel filter could be restricting fuel flow, so replace them. A clogged air filter could also be the cause, so check the signal ring position of the service indicator. Other potential causes include a defective injector or injection pump, so replace them. If the engine is overloaded, it is recommended to contact Service.

What causes high charge-air temperature in MTU 16V 2000 G23 Engine?
- A
  aalvarezSep 3, 2025
  High charge-air temperature in the MTU Engine can result from a few issues. An incorrect coolant concentration could be the cause, so check it. Additionally, a high air-intake temperature could be the problem, so check the fans and air supply/ventilation ducts. If the engine is contaminated, it is recommended to contact Service.

Why is MTU 16V 2000 G23 Engine exhaust gas white?
- G
  gdavisSep 12, 2025
  White exhaust gas from the MTU Engine can occur for a few reasons. If the engine is not at operating temperature, run it until it reaches the correct temperature. Water in the fuel can also cause this issue, so check the fuel system on the fuel prefilter and drain the fuel prefilter. Leaking may be the cause, so it is recommended to contact Service.
