When topping up the coolant, follow the instructions on the packaging. Never top up with water only. The risk of freezing increases with both too little and too much coolant concentrate.
If there is coolant under the car, if there is coolant smoke, or if more than 2 litres (approx. 2 quarts) have been filled, always call for recovery to avoid the risk of engine damage due to a defective cooling system when attempting to start the car.
Warning
The coolant may be very hot. Never open the cap when the coolant is hot. If a top-up is required, unscrew the expansion tank cap slowly to allow any overpressure to disappear.
Lift off the rubber strip by pressing it inward in the engine compartment.
Detach the flap in the plastic cover by folding out the release catch and turning the flap upward.
Screw off the cap and top up with coolant if necessary. The coolant level must lie between the MIN and MAX marks on the expansion tank.
Important
- Mix the coolant with approved quality water. In the event of any doubt about water quality, used ready-mixed coolant in accordance with Volvo recommendations.
- Make sure that the coolant mixture is 50% water and 50% coolant.
- Always use coolant with anti-corrosion agent as recommended by Volvo.
- Only new coolant should be used when replacing major cooling system components to ensure the system has sufficient corrosion protection.
- The engine must only be run with a well-filled cooling system. Otherwise, temperatures that are too high may occur resulting in the risk of damage (cracks) in the cylinder head.
- A high content of chlorine, chlorides and other salts may cause corrosion in the cooling system.
