If there is a risk of freezing
Use a mixture of 50% Volvo Penta antifreeze (gly-
col) and 50% pure water (according to ASTM
D4985). This mixture will protect against freezing to
a temperature of approx. –40°C and should be used all
year round.
IMPORTANT! Even if the temperature is never
as low as –40°C, the above mixture ratios must
be used. This is to ensure maximum anti-corro-
sion protection.
Mix the glycol with the water in a separate container
before filling the cooling system.
WARNING! Glycol is harmful to health (dan-
gerous if ingested).
IMPORTANT! Alcohol must not be used in the
cooling system.
If there is no risk of freezing
When there is never a risk of freezing, water may
(according to ASTM D4985) be used as coolant with
the addition of the Volvo Penta anti-corrosion agent.
However, we recommend that a mixture of Volvo
Penta glycol and pure water is used all year, re-
gardless of the climate.
Mixture ratio 1:30. Run the engine to operating tem-
perature after filling. This is to allow the additive to
work as efficiently as possible.
If the operation time exceeds 500 hours per annum,
the anti-corrosion agent for the coolant must be
complemented with ½ litre anti-corrosion agent eve-
ry 500 hours.
WARNING! Anti-corrosion agents are harmful
to health (dangerous if ingested).
IMPORTANT! Never mix antifreeze (glycol)
and anti-corrosion agents. The two combined
can produce foam and drastically reduce the
coolant's effectiveness.
