10.10 GENERATOR COOLING SYSTEM
10.10.1 Closed oil coolant
In the closed cooling system, the seawater circulates through separate
chambers within the oil exchanger or manifold to cool the engine coolant.
The seawater then mixes with the engine exhaust and exits from the
exhaust outlet.
Consult the generator manual for the location of the protective anodes in
the cooling system. Check the anodes at the intervals prescribed in the
generator manual. The anodes protect the cooling system from corrosion
damage; if the anodes are wasted away, corrosion protection will cease.
See the Sacrifical Anodes section in the MAINTENANCE chapter in this
manual.
Coolant Check and Filling
See manufacturer’s manual.
Flushing and Cleaning Procedure
See manufacturer’s manual.
Impeller Inspection and Replacement Procedure
See manufacturer’s manual.
Sacrificial anodes
The generator has internal zinc anode(s) to help prevent internal
corrosion. Consult the generator manual for instructions on checking and
replacing the anode(s). Failure to replace the zinc anode at the
recommended service intervals will cause internal corrosion of the
generator’s cooling system.
