CAUTION
•
Do not ingest the contents. May cause
damage to organs (kidneys).
•
Use premixed coolant according to Vol-
vo's recommendations. If concentrated
coolant is used, make sure that the cool-
ant mixture is 50% coolant and 50%
water of acceptable quality.
•
Do not mix different types of coolant.
•
To help ensure sufficient corrosion pro-
tection in the system, only use new cool-
ant when replacing larger components in
the cooling system.
•
Never run the engine unless the cooling
system is properly filled. An improperly
filled cooling system could lead to high
temperatures and cracks in the cylinder
heads.
•
High levels of chlorine, chlorides and
other salts may cause corrosion in the
cooling system.
