When topping up the coolant, follow the instruc-
tions on the packaging. Never top up with water
only. The risk of freezing increases with both too
little and too much coolant concentrate.
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.
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 recommendations.
•
When changing coolant/replacing cool-
ing 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, tempera-
tures that are too high may occur result-
ing in the risk of damage (cracks) in the
cylinder head.
For capacities and for standards regarding water
quality; see Coolant - grade and volume (p. 423).
Brake and clutch fluid - level
Brake and clutch fluid level should be between
the reservoir
MIN
and
MAX
marks.
Checking the level
Brake and clutch fluid have a common reservoir.
The level must be between the
MIN and MAX
marks that are visible inside the reservoir. Check
the level regularly.
Change the brake fluid every other year or at
every other regular service.
The fluid should be changed annually on cars
driven in conditions requiring hard, frequent brak-
ing, such as driving in mountains or tropical cli-
mates with high humidity.
For capacities and recommended brake fluid
grade, see Brake fluid - grade and volume
(p. 425).
WARNING
If the brake fluid is under the MIN level in the
brake fluid reservoir, do not drive further
before topping up the brake fluid. Volvo rec-
ommends that the reason for the loss of
brake fluid is investigated by an authorised
Volvo workshop.
