Refilling coolantCoolant helps keep the gasoline engine at the proper 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 on the 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 coolant will 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 in the engine compartment.
Remove the plastic cover by folding out the catch and lifting the cover upward.
Unscrew the expansion tank cap and add coolant. The level should be between the MIN and MAX marks on the tank.
Put the other components back in place in the reverse order.
CAUTION
• High levels of chlorine, chlorides and other 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.
