MAINTENANCE AND SERVICING
332
Engine compartment – coolant
Normally, the coolant does not need to be
changed. If the system must be drained, consult
a trained and qualified Volvo service technician.
Level check and filling
Location of the coolant reservoir
See Fuel tank volume – specification and volume
(p. 377) for information on cooling system
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.
•
If there is coolant under the vehicle, if you
detect coolant fumes or if it necessary to
top up with more than approx. 2 qts (2 lit-
ers) of coolant, engine damage could
occur if the vehicle is driven. Have it
towed to an authorized Volvo workshop.
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.
