Cooling system
The genset 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.
Coolant specifications
It is recommended use Solé Diesel 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 genset coolants may affect warranty coverage, cause an internal build-up of rust and
scale and/or shorten genset life.
Never mix different types of coolants. This may adversely affect the properties of the genset coolant.
Maintenance task. Coolant check
Allow the genset 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 genset
has cooled. Check the coolant level at the tank, the level must be approximately 3/4 full.
