Coolant
WARNING!
All coolant is hazardous and harmful to the
environment. Do not consume. Coolant is flammable.
IMPORTANT:
Always use the same type of coolant that is already in
the engine.
Different types of coolant must not be mixed with each
other.
Risk of reduced cooling function and performance by
clogging and isolation.
Coolant shall be based on Organic Acid
Technology (OAT).
Follow the mixing recommendation on the
product.
The coolant should be mixed with distilled, deionized
water. For Volvo Penta specified water requirements;
refer to Water Quality, page 105.
NOTICE! Always use “Ready Mixed” coolant if water
quality cannot be determined or if it does not fulfill
ASTM D4985.
NOTICE! Never mix more than 60% concentrated
coolant with water. A greater concentration provides
reduced cooling effect with the risk for overheating and
reduced freeze protection.
