fluid. These may leave an oily film on the

NOTICE

Never mix suitable cleaning agents with
other cleaning agents. This can cause the
ingredients to separate and block the
washer jets.
Coolant
Introduction to the topic
Do not work on the cooling system unless
you are familiar with the task, aware of the
general safety procedures and have the cor-
rect equipment, service fluids and suitable
tools. Failing to carry out work correctly can
cause serious injuries → page 315. The work
should be carried out by a qualified workshop
if you are uncertain. Volkswagen recom-
mends using a Volkswagen dealership for this
purpose.
Information on warning and indicator lamps
that light up can be found in the trouble-
shooting sections at the end of the chapter
WARNING
Coolant is toxic.
·
Coolant should only be kept in sealed
original containers in a safe place.
·
Never store coolant in empty food con-
tainers, bottles or any other non-original
containers as people finding these con-
tainers may then drink the coolant.
·
Coolant must be stored out of the reach
of children.
·
The amount of correct coolant additive
used must be sufficient for the lowest
ambient temperature that you expect
the vehicle to be exposed to.
·
Coolant can freeze at extremely cold
outside temperatures, causing the vehi-
cle to break down. Vehicle occupants
with inadequate winter clothing could
then freeze to death as the heating will
also no longer function.
Coolant and coolant additives can pol-
lute the environment. Spilt service flu-
ids must be collected and disposed of proper-
ly and in an environmentally responsible way.
Coolant specification
Please refer to , and on page 309
and at the start of the chapter on page
The cooling system is filled at the factory
with a mixture of specially prepared water
and at least 40% coolant additive.
Inform yourself at a qualified workshop about
which coolant is suitable for your vehicle.
Volkswagen recommends using a Volkswagen
dealership for this purpose.
The proportion of coolant additive must
al-
ways
be at least 40% to protect the cooling
system. If greater frost protection is required
in very cold climates, the proportion of anti-
freeze additive can be increased. However,
the percentage of coolant additive should not
exceed 55 %, as this would reduce the frost
protection and the cooling effect.
The coolant additive is dyed purple. The mix-
ture of water and a coolant additive offers
anti-freeze protection down to -25°C (-13°F),
protects the alloy parts in the cooling system
against corrosion, prevents limescale depos-
its and significantly increases the boiling
point of the coolant.
When refilling the coolant, a mixture of dis-
tilled water and at least 40% of the suitable
coolant additive must be used in order to ob-
tain the optimum corrosion protection
