Coolant
Location of the coolant reservoir
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.
See page 364 for information on cooling sys-
tem capacities.
CAUTION
•If necessary, top up the cooling system
with Volvo Genuine Coolant/Antifreeze
only (a 50/50 mix of water and anti-
freeze).
•Different types of antifreeze/coolant
may not be mixed.
•If the cooling system is drained, it
should be flushed with clean water or
premixed anti-freeze before it is refilled
with the correct mixture of water/anti-
freeze.
•The cooling system must always be
kept filled to the correct level, and the
level must be between the MIN and
MAX marks. If it is not kept filled, there
can be high local temperatures in the
engine which could result in damage.
Check coolant regularly!
•Do not top up with water only. This
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.
•Do not use chlorinated tap water in the
vehicle's cooling system.
WARNING
•Never remove the expansion tank cap
while the engine is warm. Wait until the
engine cools.
•If it is necessary to top off the coolant
when the engine is warm, unscrew the
expansion tank cap slowly so that the
overpressure dissipates.
Brake fluid
Location of the brake fluid reservoir
Checking the levelThe fluid reservoir is concealed under the
round cover at the rear of the engine compart-
ment. The round cover must be removed first
before the reservoir cap can be accessed.
