Maintenance
Cooling system
The cooling system ensures that the engine works at the right temperature. It is a closed system and must there-
fore always be filled with a mixture of at least 40% concentrated coolant and 60% water, to offer protection from
interior corrosion, cavitation and frost bursting.
We recommend that you use “Volvo Penta Coolant, Ready Mixed” , or “Volvo Penta Coolant” (concentrated)
mixed with pure water acc. to the specification, please refer to “Coolant. Mixing”. This grade of coolant is the only
one that is developed for and approved by Volvo Penta.
The coolant should contain a good grade of ethylene glycol and a suitable chemical formula for full engine protec-
tion.
The use of only an anti-corrosion preparation is not permissible for use in Volvo Penta engines. Never use
water by itself as the coolant.
IMPORTANT! Coolant fluid should be used all year round. This also applies in areas where there never is
any risk of frost, to give the engine full corrosion protection.
Future warranty claims related to engine and accessories may be refused if an unsuitable coolant has been
used, or if the recommendation for coolant mixture has not been observed.
NOTE! The corrosion protection additives become less effective as time passes, which means that the coolant
must be changed. Please refer to the “Maintenance Schedule”. The cooling system should be flushed when the
coolant is changed, please refer to “Cooling system. Flushing”.
“Volvo Penta Coolant” is concentrated coolant that
should be mixed with water. It has been prepared to
work best with Volvo Penta engines and offers excel-
lent protection against frost and cavitation damage,
plus frost bursting.
“Volvo Penta Coolant, Ready Mixed” is ready-
mixed coolant, 40% “Volvo Penta Coolant” and 60%
water. This mixture protects the engine from corrosion
damage, cavitation damage and frost bursting down to
-28°C (-18.4°F).
