Changing coolant
Normally, the coolant does not need to be
changed. If the system must be drained, con-
sult a trained and qualified Volvo service tech-
nician.
NOTE
Do not top off with water only. This reduces
the rust-protective and antifreeze qualities
of the coolant and has a lower boiling point.
It can also cause damage to the cooling
system if it should freeze. Top off with Volvo
Genuine Coolant/Antifreeze only (a
50/50 mix of water and antifreeze)
CAUTION
The cooling system must always be kept
filled to the correct level. If it is not kept filled,
there can be high local temperatures in the
engine which could result in damage. Dif-
ferent types of antifreeze/coolant may not
be mixed.
WARNING
Never remove the radiator cap while the
engine is warm. Wait until the vehicle cools.
