In there is no of risk of freezing
When there is never a risk of freezing water may be
used as coolant with addition of Volvo Penta anti
corrosion agent.
Mix according to the instructions on the packaging.
Warm up the engine after filling to allow the additive to
work as efficiently as possible.
If operating hours exceed 600 hours per annum the
coolant anti corrosion must be complemented with ½
liter anti corrosion agent every 600 hours.
WARNING! Anti-corrosive agents are harmful to
health (dangerous if ingested).
IMPORTANT! Never mix antifreeze (glycol) and
anti-corrosive agents. The two combined can
produce foam and drastically reduce the cool-
ant’s effectiveness.
Coolant level. Checking and topping up
WARNING! Do not open the engine coolant
system filler cap when the engine is still hot
except in an emergency. Steam or hot coolant
may spray out.
Turn the filler cap to the first stop and let any pressure
escape from the system before removing the cap. Top
up coolant if necessary. The level should lie between
the filler neck lower edge and the level spur (1).
Reinstall the filler cap.
If a separate expansion tank is installed (optional
extra), the coolant level should be between the MAX
and MIN levels on the extra expansion tank.
IMPORTANT! When filling a completely drained
system the coolant level must be checked after
an hours use because the system is self bleed-
ing. Top up if required.
Maintenance: Freshwater system
