Normally, the coolant does not need to be changed. If the system must be drained, use the following
procedure:
1 Remove the expansion tank cap.
2 Move the temperature adjustment control to max. heat. Open the drain cocks at the rear left of the
engine block and at the bottom right corner of the radiator.
3 Disconnect the lower right radiator hose.
Filling:
4 Close the drain cocks and reconnect the hose.
5 Fill the expansion tank to the MAX mark or slightly above.
6 Run the engine until hot. Check the cooling system connections for tightness. Recheck the coolant
level.
Capacity: Approx. 7.6 US qts. (7.2 liters)
Turbo-charged models - 7.4 US qts. (7.0 liters)
Coolant: Volvo Genuine Coolant/Antifreeze only
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.
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.
