Verification and replacement
If for weather reasons further protection is
necessary, the pr
oportion of additiv
e 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 syst
em, the engine may fail lead-
ing to 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 cool
ants which are not ap-
proved by SEAT.
●
If the fluid in the expansion t
ank 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 envir
onment. If any fluids ar
e spilled,
they should be collected and correctly dis-
posed of, with respect to the environment.

Top up coolant when the level is below the
(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 drive system is
cold, the coolant level should be between
the marks

Fig. 161. With the drive system
hot, the level may be slightly above the top
mark.
Topping up coolant
–
Allow the drive system to cool.
