2017 Seat Leon 5D coolant reservoir

The essentials
To protect the cooling system, the percentage
of a
d
ditive 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 ››› 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

Always be aware of the danger of injury and
scalding as well as the risk of accident or fire
when working in the engine compartment
(e.g. when checking and refilling fluids). Al-
ways observe the warnings listed below and
follow all general safety precautions. The en- gine compartment of the vehicle is a poten-
tia
l

ly hazardous area ››› .
WARNING
● Swit c

h the engine off, remove the key from
the ignition and apply the hand brake. If the
vehicle has a manual gearbox, place the lever

place the selector lever in position P. Wait for
the engine to cool down.
● Keep children away from the engine com-
partment
