Refilling coolant
When refilling coolant, follow the instructions on the package. Never fill the cooling system with only water. The risk of freezing is increased with too 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 (about 2 quarts) of coolant has been added to the system, there could be something wrong with the cooling system and starting the vehicle could damage the engine. Call a tow truck and do not attempt to start the engine.
Warning
The coolant can be very hot when the engine has been running. Always let the coolant cool off before unscrewing the cap to refill.
When refilling – carefully unscrew the cap to release any excess pressure.
Unscrew the expansion tank cap and fill coolant as needed. The level should be between the MIN and MAX marks on the expansion tank.
Important
- Coolant is harmful if swallowed and may cause damage to organs.
- Only use coolant of a grade approved by Volvo. If concentrated coolant is used, make sure that the coolant mixture is 50% coolant and 50% water of acceptable quality.
- Hard water and water with high levels of chlorine, chlorides and other salts or contaminants may cause corrosion in the cooling system.
- Do not mix different types of coolant.
- When replacing larger components in the cooling system, always replace all coolant with new coolant.
- Only operate the engine when the cooling system is filled to the correct level. A too-low coolant level can lead to overheating and engine damage.
