Opel genuine parts and
accessories
We recommend the use of “Opel genuine
parts and accessories” and conversion
parts released expressly for your vehicle
type. These parts have undergone special
tests to establish their reliability, safety and
specific suitability for your vehicle. Despite
continuous market monitoring, we cannot
assess or guarantee these attributes for
other products, even if they have been
granted approval by the relevant
authorities or in some other form.
“Opel genuine parts and accessories” and
conversion parts approved by Opel can be
obtained from your Op el Partner, who can
provide comprehensive advice about
permitted technical changes and ensure
that the part is installed correctly.
A note on safety
To avoid the possibility of injury, only carry
out engine compartment checks (e.g.
checking the brake fluid level or the engine
oil level) when the igni tion is switched off. Never carry out any re
pairs or adjustment
and maintenance work on the vehicle
yourself. This especially applies to the
engine, chassis and safety parts. You may,
out of ignorance, infringe the provisions of
the law and, by not performing the work
properly, you may endanger yourself and
other road users.
Checking and topping up fluids
To aid identification, the engine oil filler
cap, the coolant filler cap, the lid of the
fluid container for the windscreen washer
system and the handle of the engine oil
gauge (dipstick) may be coloured yellow.
9 Warning
The cooling fan may be operated by a
thermoswitch and can therefore start to
operate unexpectedly, even when the
ignition is switched off; risk of injury.
Electronic ignition systems generate very
high voltages. Do not touch the ignition
system; high voltage can be fatal.

Engine oil
Information on engine oils - see page 213.
Engine oil level and consumption
It is normal for every engine to consume
some oil, and it is sometimes necessary to
check and top up the engine oil level
between oil changes.
For this reason, the engine oil level should
be checked every 500 km (300 miles) or
before starting a long trip. The illustrations show checking and
replenishing the engine oil in the Z 24, Z 32
petrol engines and the
Z 20 diesel engines
respectively.
To check the level, remove dipstick from
the dipstick tube, wipe it clean and re-insert
it as far as it will go. After pulling the
dipstick out again, check the oil level,
ensuring it is between the lower and upper
(or MIN and MAX) marks. Engine oil level check and topping up
The engine oil level must be checked with
the vehicle horizontal and with the engine
(which must be at operating temperature)
switched off. Wait a few minutes before
checking the level to allow the normal oil
accumulation in the engine to drain back
into the oil pan.
9 Warning
Do not allow the engine oil level to drop
below the minimum level.

Self-help, vehicle care194
Engine oil change, oil filter change
Engine oil changes are to be carried out
depending on time intervals or kilometre/
mileage intervals, since oil loses its
lubrication properties not only through
engine operation but also through ageing.
We recommend that you use genuine Opel
oil filters.
Remember to reset the engine oil life
monitor 3 whenever the engine oil is
changed.
Engine oil life monitor 3
The engine oil life monitor lets you know
when to change the oil. Based on driving
conditions, the kilometre/mileage interval
at which an oil change will be indicated can
vary considerably.
For the system to work properly, it must be
reset every time the oil is changed. Consult
a workshop.
When the system has calculated that oil life
has been diminished, control indicator C
illuminates in the instrument panel -
see page 73. Engine oil needs changing
within approx. 1000 km (600 miles). Engine
power may be decreased.Diesel fuel filter
Drain diesel fuel filter of residual water at
every engine oil change.
Place a container underneath the filter
housing. Turn drain plug, located on the
left of the filter housing, anti-clockwise
using a suitable screwdriver, to drain off
the water.
The filter is drained as soon as diesel fuel
emerges from the port. Retighten the drain
plug by turning it clockwise.
With engine switched off, turn ignition key
to ON, wait approx. 5 seconds, and turn
key to LOCK to perform priming operation.
Perform this operation 3 times or more
while the engine is switched off, to avoid air
entering the fuel line.
9 Warning
Used engine oil filters and empty oil
containers should not be disposed of as
domestic refuse. We recommend that
you entrust oil and oil filter changes to a
workshop who is familiar with legal
requirements regarding disposal of used
oil and can thus help to protect both the
environment and your health.
Engine oil is a danger to health; avoid
prolonged contact with skin and wash
exposed areas thoroughly.

Self-help, vehicle care195
Check diesel fuel filter at shorter intervals if
the vehicle is subjected to extreme
operating conditions such as high humidity
(primarily in coastal areas), extremely high
or low outside temperatures and
substantially varying daytime and night-
time temperatures.
If there is water in the diesel fuel filter,
control indicator
N illuminates in the
instrument panel - see page 73. Drain the
water immediately.
Coolant
During operation, the system is
pressurized. The temperature may
therefore rise to over 100 °C.
The antifreeze provides excellent corrosion
protection for the cooling and heating
system, as well as freeze protection down
to -28 °C.
Certain types of antifreeze can lead to
engine damage. We therefore strongly
recommend the use of antifreeze that has
been approved by Opel.
Antifreeze and corrosion protection
Before the start of the cold weather season,
have the coolant checked for correct
concentration by a workshop. The amount
of antifreeze must provide protection down
to approx. –28 °C. If the antifreeze
concentration is too low, this reduces
protection from fr eezing and corrosion.
Top up antifreeze if necessary.
If coolant loss is topped up with
demineralised water, have antifreeze
concentration checked and more
antifreeze added as necessary. Coolant level
Hardly any losses occur since the cooling
system is sealed and it is thus rarely
necessary to top up the coolant.
The coolant level in the expansion tank
should be between the
MIN and MAX
marks when the system is cold.
9 Warning
Antifreeze is a danger to health: it must
therefore be kept in the original container
and out of the reach of children.

Self-help, vehicle care196
When the engine is at operating
temperature, coolant level rises. It falls
again when the system cools. If it falls
below the MIN mark when the system is
cold, the coolant must be replenished.
Top up antifreeze. If no antifreeze is
available, top up with clean tap water.
If tap water is unavailable, distilled water
can be used.
When you top up with tap water or distilled
water, add concentrated antifreeze and
possibly mix in antifreeze as well. Have the
cause of the coolant loss eliminated by a
workshop.
Too low a coolant level can cause engine
damage.
When closing, tighten coolant filler cap as
far as it will go. Coolant temperature
Control indicator
W illuminates when
coolant temperature is too high. Check
coolant level:
z Coolant level low:
Top up coolant. Pay attention to the
instructions given under "Antifreeze and
corrosion protecti on" and "Coolant
level". Have the cause of the coolant loss
remedied by a workshop.
z Coolant level OK:
Have the cause of increased coolant
temperature remedied by a workshop.
Brake fluid
Brake fluid level
9 Warning
Allow engine to cool down before
removing coolant filler cap. If steam is
visible, move away from the vehicle until
the engine is cool.
Remove coolant filler cap carefully so
that pressure can escape slowly,
otherwise there is a risk of scalding.
9 Warning
Caution - brake fluid is poisonous and
corrosive. Do not allow it to contact eyes,
skin, fabrics or painted surfaces; direct
contact may cause injuries and damage.
