4-cylinder injection engine (2.0 l direct injection engine, turbocharger) - Edition 02.2011
– Remove spring-type clip -2 and detach bottom coolant hose
-1- from radiator -3-.
Note
Observe environmental regulations for disposal.
Filling
Note
G 13 is used as the anti-freeze in series production.
♦
Only demineralised / distilled water to standard VDE-0510
♦
may be used for mixing. Tap water does not have the required
quality to ensure the coolant's function.
Only G 13 and G 12 plus-plus in accordance with TL VW 774
♦
G may then be used as coolant additive.
G 13 Plusplus prevents frost and corrosion damage and scal‐
♦
ing and also raises the boiling points. Therefore, the cooling
system must be filled all year round with coolant additive.
Because of its higher boiling point, the coolant improves en‐
♦
gine reliability under heavy loads, particularly in countries with
tropical climates.
Frost protection is required down to about -25°C (in countries
♦
with arctic climates down to about -35°C).
The coolant concentration must not be reduced by adding wa‐
♦
ter even in warmer seasons and in warmer countries. The
coolant additive concentration must be at least 40%.
If a stronger anti-freeze mixture is necessary due to harsher
♦
weather conditions, the percentage of G 13 and G 12 Plusplus
can be increased. But only to 60% (frost protection to approx.
-40°C), otherwise frost protection and cooling effectiveness
are reduced again.
If radiator, heat exchanger, cylinder head or cylinder head
♦
gasket is renewed, do not reuse old coolant.
The refractometer -T10007- is recommended for determining
♦
the current anti-freeze density.
Recommended mixture ratios:
Frost protection Anti-freeze
to ratio
-25°C 40%
-35°C 50%
