Lift off the rubber strip by pressing it
inward in the engine compartment.
Detach the flap in the plastic cover by
folding out the release catch and turning
the flap upward.
Screw off the cap and top up with coolant
if necessary. The coolant level must lie
between the MIN and MAX marks on the
expansion tank.
IMPORTANT
Harmful if ingested. May cause organ
•
(kidney) damage.
Use ready-mixed coolant as recom-
•
mended by Volvo. If concentrated liq-
uid is used, make sure that the ratio is
50 % coolant to 50 % water of an
approved quality.
Do not mix different coolants.
•
Only new coolant should be used
•
when replacing major cooling system
components to ensure the system has
sufficient corrosion protection.
The engine must only be run with a
•
well-filled cooling system. Otherwise,
temperatures that are too high may
occur resulting in the risk of damage
(cracks) in the cylinder head.
A high content of chlorine, chlorides
•
and other salts may cause corrosion in
the cooling system.
