Coolant - level
The coolant cools the internal combustion
engine to the correct operating temperature.
The heat that is transferred from the engine to
the coolant can be used to heat the passen-
ger compartment.
The coolant level must lie between the
MIN
and MAX marks on the expansion tank.
Checking the level and topping up
When topping up the coolant, follow the
instructions on the packaging. Never top up
with water only. The risk of freezing increases
with both too little and too much coolant con-
centrate.
WARNING
Coolant can be very hot. If the coolant
requires topping up when the engine is at
operating temperature, unscrew the
expansion tank cap slowly to gently
release the overpressure.
For capacities and for standards regarding
water quality; see Coolant - grade and vol-
ume (p. 416).
Check the coolant regularly
The level must be between the MIN and MAX
marks on the expansion tank. If the system is
not filled sufficiently, high temperatures could
occur, causing a risk of damage to the
engine.
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
cooling system components, flush the
cooling 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. Otherwise,
temperatures that are too high may
occur resulting in the risk of damage
(cracks) in the cylinder head.
