106 Attention
Particular care should be
taken

when working in the engine
com­
partment!

•
Switch off engine, remove ignition key.

•
Pull handbrake on firmly.

•
Move gear lever into neutral or
"P"
position.

•
Allow engine to cool off.

•
As long as the engine is at op­
erating temperature:

-
Do not put your hand into the radiator fan, it could switch on

suddenly.

-
Do not open the radiator cap be­
cause
the cooling system is

under
pressure.

•
Avoid causing short circuits in
the electrical system - particular­ ly at the
battery
-.
•
If tests have to be
carried
out

with
the engine running,
there
is
an additional danger
present

from rotating parts - e.g.
V-belts,
generator, radiator fan etc. - and
from the high voltage ignition
system.

Attention must be paid to the warnings given in this Instruc­
tion Manual and to the generally
applicable
safety regulations.
When topping up fluids one
should
ensure
that
they are not mistaken,

one
for the other, under any
circum­

stances,
otherwise serious
func­

tional defects
will
result.
So
that
leaks
are quickly de­
tected
the ground underneath
the vehicle should be checked
reg­

ularly.
If spots as caused by oil or

other
operating fluids can be seen, the vehicle should be
taken
to the
workshop for checking.

oils. Due to their limited
i-scosity
ranges these oils are not generally
j_::eptable for all year round use. "erefore these oils should only be used in

-
:reme climatic
zones.

•
When using SAE 5 W-30 multigrade oil, xntinuous high engine speeds and engine

seeding
should be avoided. This restriction
::es
not apply to multigrade-improved lu-
r city oils.
Checking
oil
level

Every
engine uses a certain amount of oil.

The
oil
consumption
can be up to 1.0
litres per 1000 km - see also page 80. The
engine oil level must therefore be checked
at regular intervals, preferably when filling
the tank and before a long journey.

The
location of the dipstick is shown in the illustration.

The
vehicle must be on a level surface when
checking
the oil level. After stopping engine
wait a few minutes for the oil to drain back
to the sump.

Then
pull the dipstick out, wipe it
with
a
clean
cloth and insert again.

Then
pull dipstick out again and check the oil
level:

ATF.

Schedule.
Because of the disposal

the
special

necessary
and the
specialist
knowledge
re­
quired,
the ATF
changing
should

preferably
be
done
by a
Volkswagen
dealer.

Notes

•
When
there
is no
lubricant
in the
manual
or
automatic
gearbox,
the

engine
must
not be
started
and the
vehicle may only be
towed
with

driving
wheels
lifted.

• No
additives
may be
mixed
with
the lubricants.

Checking
coolant
level

The
expansion tank
is in the
engine
com­
partment on the bulkhead
-
see Fig.

The
correct coolant level
is
essential
to
the satisfactory operation
of
cooling system.
For
this reason, the coolant level should
be

checked
regularly,
and
this
is
best done
when refueling.

The
level
can
only
be
checked properly
when engine
is
not running.

The
coolant level must be between the MIN
and
MAX marks
on the
expansion tank
when engine
is
cold
and can be
slightly
above
the MAX mark when
it
is warm.
When
the
coolant level
is too low on ve­

hicles
with
an automatic coolant level moni­
toring device,
it is
indicated by the coolant
temperature/coolant level warning lamp
flashing continuously (see page 47).

Coolant
losses

Coolant
loss normally indicates leaks in the

system.
In
this
case
the
cooling system
should
be checked by a Volkswagen dealer

without
delay.
It is
not sufficient merely
to

add
coolant.
In
a
sealed system
losses
can only occur
if

the boiling point
of
the coolant is exceeded
as
a
result
of
overheating, and coolant
is

forced out
of
the system.
Overheating can occur
if:

• the flow
of
cooling air is reduced, e.g.
by
a
radiator
muff,
very
dirty
radiator fins
(leaves,
dust, insects)
or
additional driving
lights
in
front
of
the cooling air intake.
• the boiling point
of
the coolant has been lowered by an incorrect mixture
-
see previ­

ous
page.
•
the
radiator
fan is not
working
- see
"Fan"
on next page
-
or, • the vehicle
is
driven up
a
long hill
in too

low a gear
with
engine speed very high and
at very high ambient temperatures
-
see
"Fan"
on
next page.
If
the
cause
of the
overheating cannot
be

found
and
eliminated, contact
a
Volks­
wagen dealer
as
soon
as
possible other­

wise
serious damage may
be
done
to the
engine.

Topping
up
coolant
Switch
engine
off
and let
it
cool down. Then

cover
expansion tank cap
with
a
cloth and

turn
cap carefully
to
the
left
and remove.

Attention
Do
not
remove
expansion
tank

cap
when
engine
is
hot
-
Danger
of scalding.

System
is
under
pressure.

If, in an
emergency only water
can be

added,
the
correct mixture concentration must be restored
with
the specified coolant
additive (see previous page)
as
soon
as
possible.

DO-IT-YOURSELF
- Wind jack arm up by turning the crank handle
until
the jack
just
goes under the

vehicle.

- The claw of the jack must fit round the vertical rib on the side member so
that

the jack cannot slip when vehicle is
lifted

- see illustration.
- If the ground is soft, place a large strong
piece
of packing under the jack base
plate.
- Align jack and at same time wind claw up
further
until
it contacts the vertical rib on
side
member. •
Lift
vehicle
until
the defective wheel is

clear
of ground.
• Remove wheel bolts and place them on
a
clean surface (hub cap, cloth, paper) next
to the jack and take the wheel off.
• Fit spare wheel and lightly tighten all bolts. The wheel bolts must be clean and

easy
to
turn
- do not under any circum­

stances
use grease or oil!
• Lowervehicleand fully tighten bolts indi- agonal sequence.
• Refit the wheel trim.
•
Place
defective wheel in spare wheel carrier and secure it - see page 119.

Notes

• Pay attention to the following after changing a wheel:
- Check the
tyre
pressure immediately on the spare wheel which has been fitted.
- Have the tightening torque of the wheel bolts checked
with
a torque wrench as

soon
as possible. The torque for steel
and alloy wheels is 160 Nm. If it has been established when changing
the wheel
that
wheel bolts are corroded and hard to screw in, they must be renewed be­
fore checking the tightening torque.
Until these checks have been carried out
one should, for safety reasons, only drive at

a
moderate
speed.

• The defective wheel should be repaired
as
soon as possible.

Attention
If the
vehicle
is to be
subsequent­
ly
fitted
with
wheels
or
tyres

which
differ
from
those
fitted
by
the
factory,
it is
essential
to
read

the
remarks
in the
centre
and
right
hand
columns on
page
113.
