Advice
When the coolant is topped up, use a mixture
of distilled water
and, at least, 40 % of the G
13 or G 12 p
lu
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.
Checking the coolant level and
topping up
Read the additional information carefully
›››
page 24
Before opening the bonnet, read and observe
the warnings ››› in Safety instructions on
working in the engine compartment on
page 166
.
Openin
g the c
oolant expansion tank
–
Switch off the engine and allow it to cool.
–
To prevent scalding, cover the cap on the
coolant expansion tank with a thick cloth
and carefully unscrew the cap ›››
.
Checking coolant level
–
Look into the open coolant expansion tank
and read off the coolant level.
–
If the level is below the “MIN” mark, top up
with coolant.
Topping up coolant
–
Only use new
coolant liquid.
–
Do not
fi
ll above the “MAX” mark.
Closing the coolant expansion tank
–
Screw the cap on again tightly.
The position of the coolant expansion reser-
voir is shown in the corresponding engine
compartment illustration ››› page 168.
Ensure the coolant conforms to the required
specifications. Do not use a different type of
additive if additive G 12++ is not available. In
this case use only water and bring the cool-
ant concentration back up to the correct level
as soon as possible by putting in the speci-
fied additive.
Always top up with new coolant.
Do not fill above the “MAX” mark. Otherwise
the excess coolant will be forced out of the
cooling system when the engine is hot.
The additive G 12++ can be mixed with the G
12+ in any proportion.
WARNING
Any work carried out in the engine compart-
ment or on the engine must be carried out
cautiously.
