Maintenance
Ready Mixed
Ready mixed coolant contains 40% Volvo Penta Cool-
ant / Volvo Penta Coolant VCS and 60% water. This
mixture protects the engine against internal corrosion,
cavitation and bursts due to freezing down to –28°C (–
18 F).
Coolant, Mixing
The concentrated coolant must be mixed with pure
water (distilled or de-ionized water) according to spec-
ifications; refer to Water Quality page 84.
WARNING!
All coolant is hazardous and harmful to the environ-
ment. Do not consume. Coolant is flammable.
IMPORTANT!
Different kinds of coolant must not be mixed with each
other!
Mix: 40% concentrated coolant and 60% water
This mixture protects against internal corrosion, cavi-
tation and bursts due to freezing down to –28°C (–
18°F). A 60% glycol admix lowers the freezing point to
–54 °C (–65 °F).
Never mix more than 60% concentrate in the coolant.
A greater concentration provides reduced cooling
effect with the risk for overheating and reduced anti-
freeze protection.
It is extremely important that the system be filled with
the correct coolant concentration. Mix in a separate
clean vessel before filling the cooling system. Make
sure that the liquids mix.
