Coolant expansion tank.
Open the cap in the plastic covering.
Unscrew the expansion tank cap and fill
coolant as needed. The level should not
exceed the yellow MAX mark inside the
expansion tank.
Put the components back in place in the reverse
order.
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.
