Since aluminium is used in the engines, active corrosion

is necessary in the coolant to help prevent corro­
sion damage.
Use genuine
Volvo coolant, type C (blu e-green), diluted
with clea n water in proportions of SO/50. This mixture helps
to prevent corrosion and frost damage.
• Never top-up the cooling system with water alone. Use
genuine
Volvo coolant diluted with clean water in propor­
tions of 50/50.
•
The coolant should be changed every 40,000 km
(25,000 miles) since the corrosion-protective additives in
the coolant lose their effect in time.
• The cooling system should be cleaned using solvent
PIN 1 161 328-8 prior to filling new coolant.

Important: do not operate engine if cooling system is not topped-up. Failure to observe this may cause high local tem­peratures which could cause cylinder head to fracture .
