Technical Data
Check hydraulic oil The hydraulic system of the power steering is filled with the hydraulic oil designated in the catalogue as G 002 000. Perform the inspection of the hydraulic oil level when the engine is cold and not running. The hydraulic oil level must be between the “MIN” and “MAX” markings ⇒ page 164, fig. 153
. If the level drops below the mark
ing “MIN”, it is necessary that
the power steering is checked by a specialist
garage. It is not sufficient to solely refill
with hydraulic oil.
Note
If the engine is not running (when towing) or
if the V-ribbed belt is torn, the power
steering does not operate. The vehicle is fully steerable however. There is however increased force required to turn the steering wheel.Cooling systemCoolant The job of the coolant is to cool the engine.The cooling system does not require an
y maintenance under normal operating
conditions. The coolant consists of water
with a concentration of coolant additive
of 40 %. This mixture not only provides
antifreeze protection down to -25°C but
also protects the cooling and heating system from corrosion. It also prevents the formation of scale and significantly increases the boiling point of the coolant. You must therefore not reduce the concentr
ation of antifreeze agent in the coolant
by adding water, also not during the summ
er months or in countries with a warm
climate.
The concentration of coolant additive in the coolant must be at least
40%. You can increase the amount of antifreeze
in the coolant if a higher concentration
of antifreeze is necessary for climatic
reasons but only up to 60% (antifreeze
protection down to approx. -40°C). The an
tifreeze protection tails off above that
concentration.
Vehicles exported to countries with a co
ld climate (e.g. Sweden, Norway, Finland)
are already factory-filled with a coolant which offers antifreeze protection down to about -35°C. In these countries the concentr
ation of coolant additive should be at
least 50 %. Coolant The cooling system is factory-filled with
coolant (purple in colour), which complies
with the specification TL-VW 774 G. We recommend that you use the same c
oolant additive - G12 PLUS-PLUS (purple
in colour) for topping up the system. Please contact a specialist garage if you have any questions regarding the coolant or if you wish to fill up with a different coolant. A specialist garage can also supply
you with the correct coolant additives.
Caution
•
Other coolant additives may cause operational problems which, in partic-
ular, involves significantly reducing the anticorrosion effect.•
Any faults or problems resulting from corrosion may cause a loss of
coolant and, as a consequence of th
is, result in major engine damage.
