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.
