After fuel system maintenance such as changing the fuel filter, draining the fuel/water
separator, or replacing a fuel system component.
For this operation you must follow these steps:
1.
Loosen all injection pipes.
2.
Start the engine to blow air into the injection lines and injectors automatically.
3.
When the fuel overflows from one injection pipe, tighten it and wait for the fuel to
come out of another. Repeat until all injection lines are tight.
4.
After draining, clean up fuel spill.
When fuel overflows from the injection pipes, wipe thoroughly with a cloth. Spilled fuel is a fire
hazard.

Cooling system
The engine cooling system is based on coolant circulation controlled by centrifugal pump with
thermostatic control and heat exchanger, where the coolant is refrigerated by sea water. Moreover,
the exhaust manifold is cooled also by sea water.
