6.6. 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
.

COOLAN SPECIFICATIONS
It is recommended use KRAFFT ACU 2300 CC 50% coolant or another coolant with similar
specifications. On the other hand, distilled water with an anti-freezing agent is also suitable. The
anti-freezing agent concentration according to operating conditions is specified in anti-freezing
agent package labels. It is advisable select the anti-freezing agent concentration based on a
temperature approx. 5ºC under the actual atmospheric temperature.
Other engine coolants may affect warranty coverage, cause an internal build-up of rust
and scale and/or shorten engine life.
Never mix different types of coolants. This may adversely affect the properties of the
engine coolant.
MAINTENANCE TASK. COOLANT CHECK
Allow the engine to cool. Release pressure from the cooling system before removing the
pressure cap. To release pressure, cover the pressure cap with a thick cloth and then slowly turn
the cap counterclockwise. Remove the cap after pressure has been completely released and
the engine has cooled. Check the coolant level at the tank, the level must be approximately 3/4
full.
