Refilling coolant
Coolant helps keep the gasoline engine at theproper operating temperature. The heat transfer-red from the engine to the coolant can be usedto warm the passenger compartment.
When refilling coolant, follow the instructions onthe package and use the recommended amountof coolant. Never fill the cooling system withwater only; this could lead to freezing, corrosionand engine damage.

WARNING
If the engine has been running, the coolantwill be very hot. Allow the engine to coolbefore opening the coolant expansion tank. Ifthis is not possible, open the cap very slowlyto allow pressure to dissipate.
Coolant expansion tank
Lift the rubber strip by pressing it inward inthe engine compartment.
Remove the plastic cover by folding out thecatch and lifting the cover upward.
Unscrew the expansion tank cap and addcoolant. The level should be between theMIN and MAX marks on the tank.
Put the other components back in place in thereverse order.
CAUTION
•High levels of chlorine, chlorides andother salts may cause corrosion in thecooling system.
•Only use coolants with corrosion protec-tion recommended by Volvo.
•The ratio of coolant to water is 50/50.
•Mix the coolant with tap water of drinka-ble quality.
•If maintenance is performed on the cool-ing system or if the coolant is replaced,flush the cooling system with clean waterbefore adding new a new coolant/watermixture.
•The engine may only be operated with aproperly filled cooling system. Otherwise,high temperatures and cracks in the cyl-inders may occur.
