Practical tips
Cooling system
Cool
ant specifications
The engine cooling system is supplied from
the factory with a specially treated mixt
ure of
water and at least 40 % of the additive
G12evo (TL-VW 774 J), purple. This mixture
gives the necessary frost protection down to
-25°C (-13°F) and protects the light alloy
parts of the engine cooling system against
corrosion. It also prevents scaling and con-
siderably raises the boiling point of the cool-
ant.
To protect the cooling system, the percent-
age of additive must always be at least 40 %,
even in warm climates where anti-freeze pro-
tection is not required.
If for weather reasons further protection is
necessary, the proportion of additive may be
increased, but only up to 60 %; otherwise an-
tifreeze protection will diminish and this will
worsen cooling.
When the coolant is topped up, use a mixture
of distilled water and at least 40 % of the
additive G12evo for optimal protection
against corrosion. Mixing G12evo with G13
(TL-VW 774 J), G12 plus-plus (TL-VW 774 G),
G12 plus (TL-VW 774 F), G12 (red) or G11
(green blue) engine coolants decreases pro-
tection again corrosion and should be avoi-
ded.
WARNING
If there is not enough anti-freeze in the
coolant system, the engine may fail lead-
ing t
o serious damage.
●
Ensure that the percentage of additive is
correct for the lowest expected ambient
temperature in the zone in which the vehi-
cle is to be used.
●
When the outside temperature is very
low, the coolant could freeze and the vehi-
cle would be immobilised.
CAUTION
The original additives should never be
mixed with coolants which are not ap-
pro
ved by SEAT.
●
If the fluid in the expansion tank is not
purple but is, for example, brown, this indi-
cates that the G12evo additive has been
mixed with an inadequate coolant. The
coolant must be changed as soon as possi-
ble if this is the case!
For the sake of the environment
Coolants and additives can contaminate
the environment. If any fluids are spilled,
they should be coll
ected and correctly dis-
posed of, with respect to the environment.
