CAUTION
Do not ingest the contents. May cause
•
damage to organs (kidneys).
Use premixed coolant according to
•
Volvo's recommendations. If concen-
trated coolant is used, make sure that
the coolant 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
coolant when replacing larger compo-
nents in the cooling system.
Never run the engine unless the cool-
•
ing 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.
