NOTE
Mix the washer antifreeze and water before
filling the reservoir.
TIP! Clean the wiper blades when topping up
washer fluid.
Checking and topping up the coolant
When topping up the coolant, follow the
instructions on the packaging. It is important
that the mixture of coolant concentrate and
water is correct for the prevailing weather con-
ditions. Never top up with water only. The risk
of freezing increases with both too little and too
much coolant concentrate.
IMPORTANT
•
A high content of chlorine, chlorides
and other salts may cause corrosion in
the cooling system.
•
Always use coolant with anti-corrosion
agent as recommended by Volvo.
•
Ensure that the coolant mixture is 50%
water and 50% coolant.
•
Mix the coolant with approved quality
tap water. In the event of any doubt
about water quality, used ready-mixed
coolant in accordance with Volvo rec-
ommendations.
•
When changing coolant/replacing cool-
ing system components, flush the cool-
ing system clean with approved quality
tap water or flush with ready-mixed
coolant.
•
The engine must only be run with a well-
filled cooling system. High tempera-
tures may occur, causing a risk of dam-
age (cracks) to the cylinder head.
For capacities and for standards regarding
water quality, see page 280.
Check the coolant regularly
The level must lie between the MIN and MAX
marks on the expansion tank. If the system is
not filled sufficiently, high local temperatures
could occur, causing a risk of damage (cracks)
to the cylinder head. Top up the coolant when
the level falls to the
MIN mark.
WARNING
Coolant can be very hot. If the coolant
requires topping up when the engine is at
operating temperature, unscrew the expan-
sion tank cap slowly to gently release the
overpressure.
NOTE
The engine must only be run with a well-
filled cooling system. High temperatures
can occur, causing a risk of damage
(cracks) to the cylinder head.
