Coolant
Since aluminium is used in the engines, active corrosion
protection is necessary in the
coolant to help prevent corro­
sion damage.
Use genuine Volvo coolant type C (blue-green) diluted
with clean water in proportions of 50/50. 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 25,000 miles
(40,000
km) since the corrosion-protective additives in
the coolant lose their effect in time.
• Clean cooling system with solvent (P/N 1 161 328-8)
prior to
filling new coolant.
• If tropic type radiator is filled add 0.6 (0.6) to above.
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 .
