Refilling coolant
Coolant helps keep the combustion engine at the right operating temperature. The heat trans-ferred from the engine to the coolant can beused to warm the passenger compartment.
When refilling coolant, follow the instructions on the package. Never fill the cooling system withonly water. The risk of freezing is increased withtoo low or too high amounts of coolant. If there is coolant under the vehicle, smoke from the cooling system, or if more than 2 liters (about2 quarts) of coolant has been added to the sys-tem, there could be something wrong with thecooling system and starting the vehicle coulddamage the engine. Call a tow truck and do notattempt to start the engine.
WARNING
The coolant may be very hot. Never unscrew the cap when the coolant is hot. If coolantmust be filled, unscrew the expansion tankcap slowly to relieve overpressure.

Unscrew the cover in the plastic covering.
Unscrew the expansion tank cap and fill coolant as needed. The level should not exceed the yellow MAX mark inside the
expansion tank.
Put the components back in place in the reverse order.
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.
