MAINTENANCE AND SERVICE

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.
