Engine coolant
The radiator coolant even protects against internal corrosion, cavitation, erosion and damage caused by
freezing. Different additives can also be mixed to improve the characteristics of the coolants.
NOTE
The standard supply includes
the following coolant: a mixture
of 30% antifreeze concentrated
in 70% water. This composition
allows coolant to withstand a
minimum temperature of -17.5
°C before freezing.
When changing coolant, make
sure
the
technical
specifications indicated in the
supplied manual of the engine
are complied with.
NOTE
The amount of concentrated
antifreeze to be mixed with
water must not exceed 60%.
Mixing over 60% concentrated antifreeze with water could reduce the efficiency of the heat exchange between
the engine and the coolant, thereby posing a risk of overheating the engine and resulting in less protection of
the liquid from freezing.
The coolant must be mixed with clear water: always use distilled deionised water. The water must always
conform to the requirements specified in the supplied use and maintenance manual of the engine.
NOTE
It is very important to add the
correct concentration of
antifreeze. The mixture should
be prepared beforehand in
another container before being
used to fill the radiator system.
Make sure that the liquids can
be mixed.
*Refer to the supplied manual of the engine where you will find further details for starting up the engine.
