Note
Use only purple-colour Additive -G12- for the cooling system,
♦
in compliance with TL VW 774 F.
The Additive -G12- and the additives for the cooling system
♦
which indicate "compliant with TL VW 774 D" , prevent dam‐
ages due to corrosion, freezing or mould formation, further
increasing the boiling temperature of the coolant. For this rea‐
son, the cooling system should always (all the year round)
contain the described antifreeze and anti-corrosive product
mixture.
The purple Additive -G12- (as per TL VW 774 F) can be mixed
♦
with the previous red Additive -G12- !
Because of its high boiling point, the coolant improves engine
♦
reliability under heavy loads, particularly in countries with trop‐
ical climates.
Antifreeze protection must be ensured to approximately -25 °
♦
C (in arctic climate countries, to approximately -35 ° C).
The coolant concentration must not be reduced by adding wa‐
♦
ter during hot seasons or in countries with hot climates. The
antifreeze proportion shall be at least 40%.
If because of climatic conditions, greater antifreeze protection
♦
is necessary, the percentage of Additive -G12- may be in‐
creased; however, only upto the limit of 60 % (anti-freeze
protection up to -40 °C). Where the proportion is greater, the
cooling capacity and antifreeze protection will diminish.
♦ When replacing the radiator, heat exchanger, cylinder head or
cylinder head gasket, used coolant should not be reused.
Recommended mixture proportions:
Antifreeze pro‐ Antifreeze pro‐
tection until portion
-25 °C
-35 °C
2) The coolant volume may vary according to the equipment on each vehicle.
– Close the cooling system drainage plug.
– Connect cooling fluid hose to oil radiator.
– Install engine noise insulation ⇒ Rep. Gr. 50
With Cooling system supply unit -VAS 6096- :
– Install the Engine cooling system tester -VAG 1274- adapter,
according to the vehicle, in the coolant reservoir.
– Fill the cooling system circuit with the Cooling system supply
unit -VAS 6096- ⇒ Operation instructions for the Cooling sys‐
tem supply unit -VAS 6096- .
