Check coolant level
The cooling system must be filled with coolant and not leak to operate at maximum efficiency. Check the coolant level
regularly. The level should be between the "Max" and "Min" marks on the expansion tank. The check should be made
with particular thoroughness when the engine is new or when the cooling system has been drained.
Do not remove the filler cap other than for topping-up with coolant. Frequent removal may prevent coolant circulations
between the engine tank during engine warm-up and cooling.
Changing coolant
Normally, the coolant does not need to be changed. If the system must be drained, use the following procedure:
Remove the expansion tank cap. Open the drain cock on the right side of the engine block and disconnect the lower
radiator hose.
Fill coolant through the expansion tank. The heater controls should be fully open when draining and filling.
Add coolant until the level is up to the MAX mark or slightly above.
Start the engine and run until hot. Check the cooling system connections for tightness. Also re-check the coolant level.
Capacity: See "Specifications"
coolant: Volvo Genuine Coolant/Antifreeze only
CAUTION
The cooling system must always be kept filled to correct level.
If it is not kept filled, there can be high local temperatures in the engine which could result in damage.
Different types of anti-freeze/coolant may not be mixed.
WARNING: If the engine is warm and you are going to top up coolant, unscrew the cap slowly in order to allow any
excess pressure to escape.
NOTE: Do not top up with water only. Water by itself reduces the rust-protective and anti-freeze qualities of the coolant
and has a lower boiling point. It can also cause damage to the cooling system if it should freeze.
