Cleaning and anti-corrosion
treatment
of
engine compart­ ment

Attention Before doing any
work
in the en­
gine compartment it is essential
to read the notes on page 95!

The
engine compartment and
the
outside
surface
of
the power
unit
are given anti-cor­
rosion treatment
at the
factory.
In
the
winter when
the
vehicle
is
being
driven frequently
on
salted roads, good
anti-corrosion treatment
is
very important.
For
this reason
the
entire engine compart­
ment should
be
thoroughly cleaned before
and after
the
salting period
and
then pre­

served
so
that
the
salt cannot have
a
dam­
aging effect. The
ignition must be switched off
before washing the engine.

To
prevent damage to the system
the jet from the cleaning appliance must not be directed into the
intake

openings
for the heating and venti­lation. The openings are located
above the air cleaner.
If
the engine compartment is cleaned
at
any
time
with
grease removing solutions1'
or if

one has the engine washed, the anti-corro­
sion
compound is nearly always removed as

well.
It is
therefore essential
to
ask
for
dur­

able
preservation
of all
surfaces,
seams,

joints
and components
in the
engine com­ partment
to
be carried out. This applies also
when corrosion protected parts
are re­
newed.

Volkswagen
dealers have stocks
of the
high-quality cleaning and preservation ma­
terials recommended
by the
factory
and
have
the
equipment necessary
to
apply
them.
Because
when
washing
the en­

gine
petrol,
grease
and oil de­

posits
are
washed
off, the
dirty
water
must
be
cleaned
by an oil
sep­

arator.
For
this
reason
engine
wash-
11
Only
the
correct
cleaning
solutions may
be
used
-
on no account petrol
or
Diesel.

agen dealers takes into account
to a
large
extent
the
individual annual mileage

e-ed and helps thus
to
keep
the
operating
:osts
as
low as possible.

Regular maintenance helps to

-J
ensure
that
the emissions - and
thus the environmental burden are

kept
as low as possible.

The
Inspection
Service
is
required
every
12
months
or
every
30 000 km,

. nichever occurs
first.

so and
the
Service Schedule.
~ie Service Schedule also shows what »rk
is
done
at the
Inspection
and Oil

Inange
Services.
In
arduous
operating
conditions, e.g.
extremely low ambient temperatures, very
dusty conditions etc. certain service oper­
ations should be carried
out
between the in­
tervals specified.

This
applies
in
particular
to:

• Changing
the
engine
oil

• Cleaning
or
changing
the air
cleaner
el­
ement
• Draining water from
or
renewing the fuel
filter
on the
Diesel engine

The
service operations should be carried out by
a
Volkswagen dealer because this work
requires specialist knowledge, workshop
equipment and special tools. Furthermore
this work must
be
done
in
accordance
with
out instructions.

Complete
proof
of
servicing
by a
Volks­
wagen dealer can be one
of
the stipulations
for
the
upholding
of any
warranty claims during
the
one year warranty period.

Attention
Safety
regulations
place
very

strict
limits
on the
amount
of re­

pairs
and
adjustments
to
engine

and
running
gear
parts
which
can
be
done
by the
owner.
By
tinker­
ing
with
parts
which affect
the

safety
of a
motor
vehicle
one can

endanger
oneself
and
other road users.

Altering the engine settings is detrimental to the
exhaust

emissions.
This means
that
the envi­
ronment is burdened unnecessarily
and the
fuel
consumption
also
in­
creases.

The disposal of old oil, used brake

fluid,
dirty
coolant, defective
bat­

teries or worn-out tyres etc. must be
done according to environmental
protection regulations. It is even
better
if old operating fluids and parts are used
again
and
do not become a burden on the envi­
ronment. Through "recycling" valu­

able
raw-materials and
energy
are
saved and at the same
time
it re­ lieves the load on the toxic waste

dumps.
Volkswagen dealers collect
all reusable materials and parts and

passes
them
on to the correct
agency
for recycling.

•
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.

Engine oil
T

Viscosity and
specification

A
special,
high quality multigrade oil is put in
the engine at the factory and this can be
used
all the year round - except in very cold

climates.

As
a good engine oil is a prerequisite for
trouble free operation and long engine ser­

vice
life, only a correspondingly high quality oil may be used for topping up and at oil

changes.

The specifications shown on this page must be marked either separately or together

with
other specifications, on the containers.
When topping-up, the oils can be mixed

with
one another.
The viscosity class of the oil must be se­ lected in accordance
with
the illustration. If
the ambient temperature exceeds the given range briefly, the oil does not need to be

changed.

Important
note

Quite naturally engine oils are also being
continually developed. For this reason the statements in this Instruction Manual are
only in line
with
the current state at the time
of going to press.

Volkswagen
dealers are kept up-to-date by the factory regarding changes. For this
rea­
son
the oil change should preferably be
done by a Volkswagen dealer. F

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:

Topping
up
engine
oil Unscrew the cap from oil filler opening and
pour oil in 0.5 litres at a time. Then check
level with the dipstick.
On no account must the oil level be
above area C. Otherwise oil can be drawn into the engine via the crankcase breather
and escape into the atmosphere via the ex­ haust system. On vehicles fitted with a
catalytic converter, the oil could burn inside
the converter causing it damage. Attention
When topping up the oil, do not spill it onto hot engine compo­nents - danger of fire.
Carefully close the filler cap and push the oil
dipstick in as far as possible, this will pre­
vent oil spill when the engine is running.

Changing engine
oil Not only does the engine oil deteriorate due
to use when the engine is running, but also to ageing. The engine oil change intervals depend therefore on the mileage and also
on the time elapsed.
Petrol engines
Change engine oil every 15 000 km or every 12 months (whichever comes first).
Diesel engines
Change engine oil every 7500 km or every 12 months (whichever comes first).
For further details, see Service Schedule. For petrol and Diesel engines
If the vehicle is used continuously in ar­
duous conditions, the engine oil must be
changed at shorter intervals - see also page

93.

Recommended oil and viscosity classes -
see page 96.
Attention
Old oil must be stored out of reach of children until it is dis­
posed of in the correct manner.

ojfcj
On no account must oil be
earth.

Because of the disposal
problems,
the necessary special tools anc
specialist knowledge required the engine oil and filter changing shoulc
preferably be done by a Volkswagen
dealer.

Engine

additives

No additives should be mixed with
the engine oil.
Any damage caused by the use o
such additives will not be coverec by the warranty.

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.

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.
