WinGD X92DF - Cooling Water System Without Bypass Cooling

3.2 For an engine without a bypass cooling water system (refer to Figure 8-2), and
when the liner wall temperature is between 60°C and 90°C (for example when
the engine is pre-heated or after engine full stop for a sufficient period), release
the unwanted air with a high flow rate as follows:

inlet)
3.2.1 Close the shut-off valves (001) in the cylinder liner supply pipes of the
first half of cylinders (for example cylinder 1 to 3 for a 5 or 6 cylinder
engine).
NOTE: This increases the pressure and thus the flow rate to the other
cylinders.
3.2.2 Let the cooling water flow through the other cylinder liners for
approximately ten minutes.
3.2.3 Open the shut-off valves (001) in the cylinder liner supply pipes of the
first half of cylinders.
3.2.4 Do Step 3.2.1 to Step 3.2.3 again for the second half of cylinders (for
example for cylinder 4 and 5 or for cylinder 4 to 6).
