Coolant, Mixing
WARNING!
All coolant is hazardous and harmful to the environ-
ment. Do not consume. Coolant is flammable.
IMPORTANT!
Different types of coolant must not be mixed with each
other!
Mix: 40% "Volvo Penta Coolant" (conc. coolant)
and 60% water
This mixture protects against internal corrosion, cavi-
tation and frost bursting down to –24°C (–11°F). At
60% glycol concentration, the freezing point is lowered
to –46°C (–51°F).
Never mix more than 60% concentrate (Volvo Penta
Coolant) in the coolant. A greater concentration pro-
vides reduced cooling effect with the risk for overheat-
ing and reduced frost protection.
The coolant must be mixed with distilled, deionized
water. The water must fulfil the requirements specified
by Volvo Penta; refer to Technical Data page 132.
It is extremely important that the system is filled with
the correct coolant concentration. Mix in a separate
clean vessel before filling the cooling system. Make
sure that the liquids mix.
