Coolant specifications
The engine cooling system is supplied from
the factory with a specially treated mixture of
water and at least 40 % of the additive G13
(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 considerably rai-
ses the boiling point of the coolant.
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
G13 or G12 plus-plus (TL-VW 774 G) additive
(both are purple) to obtain an optimum anti-
corrosion protection

. The mixt
ure of G13
with G12 plus (TL-VW 774 F), G12 (red) or G11
(green-blue) engine coolants will significantly
reduce anti-corrosion protection and should
therefore be avoided
