Cooling system
The cooling system must be filled with a coolant that protects the engine against internal corrosion and from
freezing if the climate requires it. Never use water alone.
The anti-corrosion additives become less effective over time. The coolant must be therefore be re-
placed. On the condition that Volvo Penta coolant recommendations are followed, the following re-
placement intervals apply.
Volvo Penta coolant (glycol mixture)
with coolant filter
Volvo Penta coolant (glycol mixture)
without coolant filter
Volvo Penta anti-corrosion agent
Every 4 years or at least every 10.000
hours
Every other year or at least every
5000 hours
Every year
IMPORTANT! The cooling system must be flushed through when the coolant is replaced. See under
heading “Cooling system Flushing”. The coolant filter (accessory) must not be changed at the same time
as the coolant. It must be replaced 6 months after the first coolant replacement and then every six
months. See under heading “Coolant filter. Replace”.
Coolant. General
IMPORTANT! To avoid blockage and / or dam-
age caused by freezing / corrosion to the en-
gine and cooling system the following recom-
mendations must be followed:
Water quality
Always use clean water which fulfils the require-
ments in ASTM D4985. If these requirements are not
fulfilled, the cooling system will become blocked
again with diminished cooling effect as a direct re-
sult. If water cannot be cleaned so these require-
ments are fulfilled, distilled water or ready mixed
coolant must be used.
