Cooling system Engine coolant specifications The engine cooling system is supplied from
the factory with a specially treated mixture of
water and, at least, 40 % of the additive
G 13
(TLVW 774 J). The engine coolant additive is
recognisable by its purple colour. This mix-
ture of water and additive gives the necessa-
ry frost protection down to -25°C (-13°F) and
protects the light alloy parts of the cooling
system against corrosion. It also prevents
scaling and considerably raises the boiling
point of the coolant.
To protect the engine cooling system, the
percentage of additive must always
be at
l e
ast 40 %, even in warm climates where an-
ti-freeze protection is not required.
If greater frost protection is required in very
cold climates, the proportion of additive can
be increased. However, the percentage of ad-
ditive should not exceed 60%, as this would
reduce the frost protection and, in turn, de-
crease the cooling capacity.
When the coolant is topped up, use a mixture
of distilled water and, at least, 40 % of the G
13 or G 12 plu

s-plus (TL-VW 774 G) additive
(both are purple) to obtain an optimum anti-
corrosion protection ››› . The mixture of G
13 with G 12 plus (TL-VW 774 F), G 12 (red) or
G 11 (green-blue) engine coolants will signifi- cantly reduce the anticorrosion protection
and should, therefore be avoided
››› .
WARNING
If there is not enough anti-freeze in the cool-
ant system, the engine may fail leading to se-
rious damage.
● Please make sure that the percentage of
additive is correct with respect to the lowest
expected ambient temperature in the zone in
which the vehicle is to be used.
● When the outside temperature is very low,
the coolant could freeze and the vehicle
would be immobilised. In this case, the heat-
ing would not work either and inadequately
dressed passengers could die of cold. CAUTION
The original additives should never be mixed
with coolants which are not approved by
SEAT. Otherwise, you run the risk of causing
severe damage to the engine and the engine
cooling system. ● If the fluid in the expansion tank is not pur-
ple but is, for example, brown, this indicates
that the G 13 additive has been mixed with
an inadequate coolant. The coolant must be
changed as soon as possible if this is the
case! This could result in serious faults and
engine damage. For the sake of the environment
Coolants and additives can contaminate the
environment. If any fluids are spilled, they
should be collected and correctly disposed
of, with respect to the environment. Topping up coolant
Read the additional information carefully
›››  page 32
Top up coolant when the level is below the
MIN (minimum) mark.
Checking coolant level – Park the vehicle in a horizontal position.
– Switch the ignition off.
– Read off the coolant level on coolant ex-
pansion tank. When the engine is cold, the
coolant level should be between the marks.
When the engine is hot, it may be slightly
above the upper mark.
Topping up coolant – Wait for the engine to cool down.
– Cover the coolant expansion tank cap with
a cloth and carefully unscrew it to the left
››› .
– Top up the coolant only if there is still cool-
ant in the expansion tank, otherwise you »
