Section 5 Cooling System
5.2 Water-Cooled Exhaust
Manifold
Each marine generator set has a water-cooled exhaust
manifold. The coolant solution circulates through the
manifold, reducing the amount of heat radiated from the
exhaust into the surrounding area.
The engine thermostat is located in the water-cooled
exhaust manifold. See Figure 5-2. See Section 1 for the
water-cooled exhaust manifold torque spec.

5.3 Closed Heat Exchanger
In a closed cooling system, seawater circulates through
separate chambers within the heat exchanger to cool
the engine coolant.
The seawater then mixes with
engine exhaust and ejects out of the exhaust outlet. See
Section 1 for coolant capacity, thermostat and pressure
cap ratings.
Note: Coolant solution.
A coolant solution of 50%
ethylene glycol provides freezing protection to
--37
°
C (--34
°
F) and overheating protection to
129
°
C (265
°
F). A coolant solution with less than
50% ethylene glycol may not provide adequate
freezing and overheating protection. A coolant
solution with more than 50% ethylene glycol can
cause engine or component damage. Do not use
alcohol or methanol antifreeze or mix them with
the specified coolant.
Consult the engine
manufacturer’s operation manual for engine
coolant specifications.
5.4 Check and Fill Coolant
Note:
Do not add coolant to a hot engine.
Adding
coolant to a hot engine can cause the cylinder
block or cylinder head to crack. Wait until the
engine has cooled.
Maintain the coolant level in the coolant recovery tank at
approximately 1/4 full. Before filling the cooling system,
close all petcocks and tighten all hose clamps. Use a
solution of 50% ethylene glycol and 50% clean,
softened water to inhibit rust/corrosion and prevent
freezing.
Add coolant, as necessary, to the coolant
recovery tank. Periodically check the coolant level on
closed systems by removing the pressure cap. Do not
rely solely on the level in the coolant recovery tank. Add
fresh coolant until level is just below the overflow tube
opening.
Note: Coolant solution.

the specified coolant.
Consult the engine
manufacturer’s operation manual for engine
coolant specifications.
