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.

– Replace the coolant reservoir cover.
– Turn off heating start device.
– Start engine and maintain an speed of about 2000 rpm for ap‐

prox. 3 minutes.

– Run engine until the radiator fan starts.
– Check coolant level and, if necessary, replenish. With engine

hot, the coolant level shall be on max. marking; with engine

cold, it must be between the max. and min. marks.
