4-cylinder diesel engine (2.0 l engine, 4 valve) - Edition 02.2011
Note
Use only coolant additive G 12 plus-plus in accordance with
♦
TL VW 774 G.
G 12, G12 plus and G 12 plus-plus must not be mixed!
♦
It is only permissible to use distilled water for mixing.
♦
G 12 plus-plus prevents frost and corrosion damage, scaling
♦
and also raises the boiling point of coolant. Therefore, the
cooling system must be filled all year round with frost and cor‐
rosion protection additives.
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 for climatic reasons greater frost protection is required, the
♦
amount of G 12 plus-plus can be increased, but only up to 60
% (frost protection to about -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 mixing ratios (use only distilled water for mixing):

The quantity of coolant can vary depending upon the vehicle
equipment.
– Install lower coolant hose and secure with retaining clip
