2016 Seat Leon 5D coolant reservoir

The essentials
even in warm climates where anti-freeze pro-
t ection i
s
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 ››› in Topping up cool-

. The mixture of G13 with
G12 plus (TL-VW 774 F), G12 (red) or G11
(green-blue) engine coolants will significant-
ly reduce anti-corrosion protection and
should therefore be avoided ››› in Topping
