Refilling coolant
When refilling coolant, follow the instructions on the package. Never fill the cooling systemwith only water. The risk of freezing isincreased with too low or too high amountsof coolant.
If there is coolant under the vehicle, smoke from the cooling system, or if more than2 liters (about 2 quarts) of coolant has beenadded to the system, there could be some-thing wrong with the cooling system and star-ting the vehicle could damage the engine. Calla tow truck and do not attempt to start theengine.
WARNING
The coolant may be very hot. Never unscrew the cap when the coolant is hot. Ifcoolant must be filled, unscrew the expan-sion tank cap slowly to relieve overpres-sure.
Coolant expansion tank, left-hand drive vehicle
Unscrew the cover in the plastic covering.
Unscrew the expansion tank cap and fill coolant as needed. The level should notexceed the yellow MAX mark inside the
expansion tank.
Put the components back in place in thereverse order.
CAUTION
Do not ingest the contents. May cause damage to organs (kidneys).
Use premixed coolant according toVolvo's recommendations. If concen-trated coolant is used, make sure thatthe coolant mixture is 50% coolantand 50% water of acceptable quality.
Do not mix different types of coolant.
To help ensure sufficient corrosion pro-tection in the system, only use newcoolant when replacing larger compo-nents in the cooling system.
Never run the engine unless the cool-ing system is properly filled. Animproperly filled cooling system couldlead to high temperatures and cracksin the cylinder heads.
High levels of chlorine, chlorides andother salts may cause corrosion in thecooling system.
