Refilling coolant
Follow the instructions on the coolant package when refilling. 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 are any signs of leakage from the cooling system, do not start the vehicle and have it towed to help prevent engine damage. Signs of leakage include coolant under the vehicle, steam from the coolant system, or if more than 2 liters (about 2 quarts) are needed when refilling.
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.
Open the cap in the plastic covering.
Unscrew the expansion tank cap and fill coolant as needed. The level should be between the MIN and MAX marks on the expansion tank.
Put the components back in place in the reverse order.
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.
