Cooling System: Coolant

Since aluminum is used in the engine, active corrosion protection in the coolant is necessary to help prevent corrosion damage. Use genuine Volvo coolant, type C (blue-green) diluted with clean water in proportions 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 proportions 50/50. The coolant should be changed regularly since the corrosion-protective additives in the coolant loose their effect in time.
