232freeze protection of temperatures down to approx. -40°C. However,the
concentration of anti-freeze must not exceed 60%, as the anti-freeze protec-
tion would then drop and the performance of the coolant system would suffer.
Vehicles for countries with cold climates (e.g. Sweden, Norway and Finland)
have factory-filled anti-freeze protection for temperatures down to -35°C. In
these countries, the concentration of anti-freeze should always be at least
50%.
Caution
•It is advisable to have the cooling system checked before the winter
season to make sure that the antifreeze concentration is adequate for the
conditions to be expected. This applies particularly if you intend to take the
car into a colder climate zone. If necessary, have the antifreeze concentration
increased to 50 - 60% as required.•Use only anti-freeze G12++ , an additive meeting the “TL-VW 774G” spec-
ification. Other anti-freezes may give considerably inferior corrosion protec-
tion. The damage caused by the use of these anti-freezes may lead to a loss
of liquid coolant, causing serious damage to the engine.•The anti-freeze G12++ can be mixed only with anti-freeze additives G11,
G12 and G12+.
Checking the liquid coolant level
The liquid coolant level can be checked at a glance.– Switch the ignition off.
– Check the coolant level on liquid coolant expansion tank ⇒fig. 181 . When the engine is cold, it should be between the
“min” and “max” marks. When the engine is hot, it may be
slightly above the “max” mark.Its location is shown in the corresponding general overview of the engine
compartment.
The liquid coolant level should be checked with the engine switched off.
The liquid coolant level is monitored by a warning lamp in the instrument
panel ⇒ page 78. However, we recommend that it should be checked occa-
sionally.

Technical Data
Liquid coolant losses
Any loss of liquid coolant normally indicates a
leak in the cooling system. In
this case the cooling system should be inspected by a specialist garage
without delay. It is not sufficient merely to top up the liquid coolant.
If there are no leaks in the system, a loss of liquid coolant can only occur if
the coolant boils and is forced out of the system as a result of overheating.
Caution
Radiator sealants must not be added to the liquid coolant. Such additives
could seriously impair the function of the cooling system.Topping up the liquid coolant
Be careful when topping up with liquid coolant.– Switch the engine off.
– Wait for the engine to cool down.
– Cover the cap on the expansion tank ⇒page 232, fig. 181 with a
cloth, and carefully unscrew the cap anti-clockwise ⇒.
– Add liquid coolant.
– Screw on the cap tightly.Make sure that the liquid coolant meets the required specifications
⇒page 231, “Liquid coolant”. Do not use a different type of anti-freeze if
anti-freeze G12++ is not available. In this case, use only water and bring the
anti-freeze concentration back up to the correct level as soon as possible.
Always top up with new liquid coolant. Do not fill above the “max” mark. Excess liquid coolant is forced out of the
system through the valve in the filler cap when the engine gets hot.
If a lot of liquid coolant has been lost, wait for the engine to
cool down before
putting in cold coolant. Failure to do so could result in serious engine
damage.
WARNING
•The cooling system is under pressure. Do not unscrew the cap on the
expansion tank when the engine is hot. Failure to comply could result in
burns.•The anti-freeze and liquid coolant can be a health hazard. Therefore,
the anti-freeze should be stored in the original container in a safe place out
of reach of children. Failure to comply could result in poisoning.For the sake of the environment
Drained off coolant should not be used again. Drain off the used coolant into
a suitable container and dispose of it in the proper manner (observe environ-
mental regulations).Radiator fan
The radiator fan can start running spontaneously.The auxiliary fan can continue to run for as long as 10 minutes after stopping
the engine – even after the ignition is switched off. It may also start running
suddenly ⇒ after some while if•stored heat raises the coolant temperature, or•the hot engine compartment is additionally heated up by the sun.
