Coolant specifications
The engine cooling system is supplied from
the factory with a specially treated mixture of
water and at least 40 % of the additive G13
(TL-VW 774 J), purple. This mixture gives the
necessary frost protection down to -25°C
(-13°F) and protects the light alloy parts of
the engine cooling system against corrosion.
It also prevents scaling and considerably rai-
ses the boiling point of the coolant.
To protect the cooling system, the percentage
of additive must always be at least 40 %, even in warm climates where anti-freeze pro-
tection is

not required.
If for weather reasons further protection is
necessary, the proportion of additive may be
increased, but only up to 60 %; otherwise an-
tifreeze protection will diminish and this will
worsen cooling.
When the coolant is topped up, use a mixture
of distilled water and at least 40 % of the
G13 or G12 plus-plus (TL-VW 774 G) additive
(both are purple) to obtain an optimum anti-
corrosion protection ››› in Checking the
c oo
l

ant level and topping up on page 194.
The mixture of G13 with G12 plus (TL-VW 774
F), G12 (red) or G11 (green-blue) engine cool-
ants will significantly reduce anti-corrosion
protection and should therefore be avoided

Removing and fitting the hubcap
● To remove, take the vehicle tool kit wire
hook and attac

trim ››› Fig. 50.
● Remove the trim by pulling it in the direc-
tion of the arro
w.
● To replace the hubcap, press the hubcap
agains

Fitting hubcaps
● It is necessary to press the hubcap against
the wheel so that
the space for the valve fits
over the tyre valve.
● Make sure that the hubcap is correctly fit-
ted all
the way around the wheel. If you are
using an anti-theft wheel lock, screw it in the
opposite position to the valve. Wheel bolt caps

● Remove the cap with the plastic clip.
The caps
protect the wheel bolts and should
be remounted after changing the tyre.
The anti-theft wheel bolt has a special cap
which is only compatible with anti-theft bolts
and cannot be used for conventional bolts. 37

If the wheel bo
lt is very tight, you may be
able to loosen it by pushing down on the end
of the wheel brace carefully with your foot.
Hold on to the vehicle for support and take
care not to slip.
Loosening wheel bolts
● Fit the wheel brace as far as it will go over

For wheels with full hubcap, the anti-theft
wheel lock must be threaded into position

se it will not be possible to mount the
entire hubcap.
● Take the adapter for anti-theft wheel bolts
out of the
vehicle tool kit.

Fig. 54. Push it on as far as it will go.
● Fit the wheel brace onto the adapter as far
as po

● Hold the wheel brace at the end and rotate
the bolt ap
proximately one turn anticlockwise
››› .Important information about wheel bolts
The wheel
rims and bo

lts have been de-
signed to be fitted to factory options. If differ-
ent rims are fitted, the correct wheel bolts
with the right length and correctly shaped
bolt heads must be used. This ensures that
wheels are fitted securely and that the brake
system functions correctly.
In some circumstances, wheel bolts from the
same model vehicle should not be used.
Wheel bolt tightening torque
The prescribed tightening torque for wheel
bolts for steel and alloy wheels is 110 Nm.
Have the tightening torque of the wheel bolts
checked as soon as possible with a reliable
torque wrench.
If wheel bolts are rusty and it is difficult to
tighten them, the threads should be replaced
and cleaned before checking the tightening
torque.
Never grease or lubricate wheel bolts or the
wheel hub threads. Although they have been
tightened to the prescribed torque, they
could come loose while driving. WARNING
If the wheel bolts are not fitted correctly they
cou l

d be released while driving leading to
loss of vehicle control and serious damage. 38
