~ne layout of the warning lamps depends on
:ne model and the engine fitted. The sym-
: ols shown here are also on the actual warn-ng lamps.

This
lamp flashes for a few seconds as a
functional check when ignition is switched
on.
If the lamp does not go out afterwards or
flashes
when driving, either the coolant
temperature is too high orthe coolant level1'
too low:
Stop,
switch
engine
off and check
level.
Add coolant if necessary.
11 Only on vehicles
with
automatic coolant level monitor(see page 102).
Attention
• Be
careful
when
opening the
coolant
expansion
tank!
When
the
engine
is hot the cooling
sys
tem is
under
pressure -
Danger
of scalding!
Therefore
let
engine
cool
down
before
unscrewing
the cap.
• Do not
touch
the fan. The fan can
switch
on suddenly -
even
when
ignition
is
switched
off.
For
further details see pages 102 and 103.
If the coolant level is in order the trouble
may be due to failure of the radiator fan.
Check
radiator fan fuse and renew if
necessary-seepage
122.
If the warning lamp does not go out al
though coolant level and fan fuse are in order, do not
drive
on - call in expert as
sistance.
If the trouble is only caused by the fan and
assuming
coolant level is in order and tem perature warning lamp is out - one can drive
on to the nearest Volkswagen dealer. In
order to make good use of the air stream for
cooling,
do not let engine idle or drive very
slowly.

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.

nere are two marks
with
which the oil level
:an be
checked.
• Outside on container (Fig.) • Inside on dipstick attached to the cap. ~he oil level should always be between the
MAX."
and "MIN" marks. When the level
"as
dropped down below the "MIN" mark
:^e
power assisted steering should be
:necked
at a Volkswagen dealer. It is not
sufficient merely to top up
with
hydraulic oil.
Note
f the power assisted steering fails at any
: me or when engine is not running (vehicle on tow) the vehicle remains fully steerable cut more force must be used to
turn
the
steering wheel. Cooling
system
Under
normal conditions the cooling
sys
tem is almost maintenance-free.
The vehicle is
fitted
with
a hinged radiator
which can be folded forward when required
- see page 104.
The cooling system is filled at the factory
with
a permanent coolant which is not
changed.
The coolant consists of water and
a
40 % concentration of our coolant additive
G
11 V8B (anti-freeze on glycol basis
with
anti-corrosion additives). This mixture not
only gives the necessary frost protection
down to -25 degrees C but also protects the
alloy parts in the cooling system against cor
rosion.
In addition it prevents scaling and ra
ises
the boiling point of the coolant.
The concentration of the coolant therefore must not be reduced in the summer or in
warm countries, by topping up
with
plain
water. The
coolant
additive
propor
tion
must
be at
least
40 %.
If greater protection against frost is re
quired, the proportion of G 11 V8B additive
can
be increased, but only up to 60 % other
wise the anti-freeze protection is reduced
and furthermore the cooling effect is im
paired.
Vehicles
for export to cold countries -s~a .
have frost protection down to -35 decrees
C.
Only
our G 11 V8B or an additive v/rs :~e
specification
TL-VW 774 B (markea or
container) should be added to the coolant.
The additives can be obtained from
Volks
wagen dealers.
Other
additives
can be
very
detri
mental
to the
anti-corrosion
effect
in
particular.
The
subsequent
corrosion
damage
can
lead
to
coolant
loss
resulting
in
major
engine
damage.

GENERAL
MAINTENANCE
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.

The coolant additive and the coolant are a danger to health.
The additive must therefore only be stored in the original
con
tainer
well
out of reach of
children.
If the coolant has to be
drained at any
time
it must be
caught and also stored in a safe
place.
Drained

not nor-
W*
mally
be
reused,
it
must

regulations.
Fan
The radiator
fan is
driven electrically
and
controlled by a thermoswitch from the
cool
ant temperature (also from the engine
com
partment temperature on some models).
Attention
After the engine has been
switched off the fan can
con
tinue running for a
while
(up to
about 10 minutes)
with
the igni
tion off. It can also
start
to run
again suddenly
after
a short time, if the coolant temperature in
creases
due to
heat
build-up.
Special
care must therefore be
taken when working in the en gine compartment. Notes
•
If
the fan is not running although the
cool
ant temperature
is
very high,
the rse
should
be
checked
and if
necessary
re
newed
-
see page 122.
• The speed
of
the fan does not depeno
or
engine
speed.
The
cooling effect cannot
therefore
be
increased
by
changing down.
As
long as
the
engine runs smoothly and
a
gradient can
be
taken
without
a
large drop in speed
it
is not necessary to change down.
Driving in
winter
To
ensure
that
the
frost protection
is ad
equate, the coolant concentration should be
checked
and
if
necessary corrected, before
the cold
season
begins.
