Notes:
1) Unleaded fuel only. Can be run on 91 octane unleaded . • RON stands for Research Octane Number, and is a measure of the ability of the fuel to withstand knocking. MON stands for Motor Octane Number, another way of measuring the same property .
(R+M)/2, also called AKI (Anti Knock Index) is a combination of these two measurements . 95 RON is equivalent to 91 (R+M)/2. 91 RON is equivalent to 87 (R+M)/2 .

Since aluminum 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 and is the only
coolant
warrantied by Volvo,
•
Never top-up with water alone, Use genuine Volvo
coolant diluted
with clean water in proportions of 50/50,
• Under normal conditions the coolant will not need to be
replaced, However, after larger repairs requiring draining
of coolant, refill with new coolants, as the old will have
been exposed
to oxidation and contamination ,
• Clean cooling system with solvent (PIN 1161328-8)
prior to
filling new coolant.

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 .
