Group 20
Coolant
Volvo Penta glycol (antifreeze) mixed 45/55 with clean water
Anti-corrosion agent
Used only in markets where there is no risk of freezing, mixed with water
3)
The anti-corrosion agent must not be mixed with glycol or other types of anti-corrosion fluid as this could result in negative
consequences.
Water quality specification:
To avoid the risk of clogging in the cooling system, the coolant should be mixed with pure water to ASTM D4985.
If any doubt about the purity of the water, distilled water or ready-mixed coolant should always be used instead
