CAUTION
• Mix the coolant with water of acceptable quality. If you are unsure of the quality ofthe water, use a Volvo-recommendedpremixed coolant.
• Make sure the coolant mixture is 50%water and 50% coolant.
• Only use coolants with corrosion protec-tion recommended by Volvo.
• To help ensure sufficient corrosion pro-tection in the system, only use new cool-ant when replacing larger components inthe cooling system.
• Never run the engine unless the coolingsystem is properly filled. An improperlyfilled cooling system could lead to hightemperatures and cracks in the cylinderheads.
• High levels of chlorine, chlorides andother salts may cause corrosion in thecooling system.
