Practical tips
increased, but only up to 60 %; otherwise
antifr
ee
ze protection will diminish and this
will worsen cooling.
When the coolant is topped up, use a mix-
ture 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 leading
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 coolants which are not ap-
proved 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 po
ssi-
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 collected and correctly dis-
posed of, with respect to the environment.
