Coolant, Mixing
WARNING!
All coolant is hazardous and harmful to the environ-
ment. Do not consume. Coolant is flammable.
IMPORTANT!
Volvo VCS coolant (yellow in color) must not be used
in Volvo Penta engines.
Different kinds 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 –28 °C (–18 °F). At
60 % glycol concentration, the freezing point is lowered
to –54 °C (–65 °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 fulfill the requirements specified
by Volvo Penta; refer to Water Quality page 98.
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.
Coolant Level, Checking and
Topping Up
Checking the coolant level
WARNING!
Do not open the coolant filler cap when the engine is
warm, except in emergencies, this could cause serious
personal injury. Steam or hot fluid could spray out.
The coolant level must be about 5 cm (2") below the
expansion tank pressure cap sealing surface.
If a separate expansion tank is fitted, the coolant level
must be between the MIN and MAX marks.
Where necessary, top up coolant in accordance with
the instructions below.
