The coolant additive is dyed purple. The mixture of water and a coolant additive offers anti-freeze
protection down to -25°C (-13°F), protects the alloy parts in the cooling system against corrosion,
prevents limescale deposits and significantly increases the boiling point of the coolant.
When refilling the coolant, a mixture of distilled water and at least 40% coolant additive - G 13 - or -
G 12 plus-plus - (TL-VW 774 G) (both of which are dyed purple) must be used in order to obtain the
optimum corrosion protection
⇒
.
Mixing - G 13 - with the coolant additives - G 12 plus - (TL-VW 774 F), - G 12 - (dyed red) or - G 11 -
(dyed blue-green) will significantly decrease the level of corrosion protection and should therefore
be avoided
⇒
.
WARNING
Insufficient anti-freeze in the coolant system can cause the engine to break down and cause serious
injuries.
ive used must be sufficient for the lowest
ambient temperature that you expect the vehicle to be exposed to.
Vehicle occupants with inadequate winter clothing could then freeze to death as the heating will
also no longer function.
NOTICE
Never mix genuine coolant additives with other coolants that have not been approved by
Volkswagen.
ts from mixing the purple
coolant additive with distilled water) but for example, brown instead of purple, - G 13 - has been
mixed with an unsuitable coolant additive. The coolant must be changed as soon as possible if this is
the case. Failure to observe this warning can result in serious malfunctions or damage to the engine
and cooling system.
Coolant and coolant additives can pollute the environment. Spilt service fluids must be collected and
then disposed of properly and in an environmentally responsible way.
