Coolant-com position-warranty
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.
