ADDITIONAL
OPERATIONS
Every 1000 kmor before long jour-
neys, check and if necessary top up:
– engine coolant fluid level
– brake/hydraulic clutch control fluid
level
– power steering fluid level
– windscreen and headlamp washer
fluid level
– tyre pressure and conditions.
Every 3000 kmcheck and if necessary
top up the engine oil level.
The use of FL Seleniaproducts is rec-
ommended which have been designed
and made expressly for Alfa Romeo cars
(see “Refuelling” in the “Technical
Specifications” chapter).
ANNUAL INSPECTION
PROGRAMME
For cars with an annual mileage
of below 20,000 km (for exam-
ple about 10,000 km) the follow-
ing yearly inspection programme
is advised:
– Check tyre conditions/wear and if
necessary adjust the pressure (including
spare wheel)
– Check operation of lighting system
(headlights, direction indicators, hazard
warning lights, boot, passenger compart-
ment, glovebox lights, warning lights,
etc.)
– Check operation of windscreen wiper
system, spray jet adjustment
– Check position/wear of windscreen
– Check front disk brake pad conditions
and wear– Sight check for conditions of: engine,
gearbox, transmission, pipes (exhaust -
fuel supply - brakes), rubber parts (boots
- sleeves - bushes etc..), brake and fuel
supply system hoses
– Check for bonnet and boot lock clean-
ness, lever cleanness and lubrication
– Check battery charge
– Sight check for conditions of various
drive belts
– Check and if necessary top up fluid
levels (engine coolant, brakes, wind-
screen washer, battery etc. )
– Change engine oil and engine oil filter
– Change pollen filter.

CHECKING LEVELS
Never smoke while
working in the engine
compartment; gas and
inflammable vapours may be pre-
sent, with the risk of fire.
When topping up take
care not to confuse the
various types of fluids:
they are incompatible with one
another and could seriously dam-
age the vehicle.fig. 1 - 1.8 T. SPARK version

ENGINE OIL (fig. 4-4a-5-6)
The engine oil should be checked with
the vehicle on a level surface a few min-
utes (about 5) after the engine has been
switched off.
Remove the dipstick (A), clean it, put it
back in completely, remove it and check
that the level is within the MINand
MAXmarks on the dipstick. The interval
between the MINandMAXmarks cor-
respond to about one litre of oil.When the engine is hot,
take care when working
inside the engine com-
partment to avoid burns.
Remember that when the engine
is hot, the fan may cut in: danger
of injury.
Do not add oil with spec-
ifications (classification,
viscosity) other than
those of the oil already in the
engine.

If the oil level is near or even below the
MINmark, add oil through the filter neck
(B), until reaching the MAXmark.
IMPORTANTIf a routine check
reveals that the level is above the MAX
mark, contact Alfa Romeo Authorised
Services to have the correct level restored.
IMPORTANTAfter topping up the oil,
before checking the level again, run the
engine a few seconds and wait for a few
minutes ater stopping it.

Used engine oil and filter
contain harmful sub-
stances for the environ-
ment. Contact Alfa Romeo
Authorised Services to have the
oil and the filter changed, as they
are equipped to dispose of the
waste oil and filters respecting
nature and the law.
SELESPEED TRANSMISSION
OIL
(fig. 7)
The Selespeed transmission oil should be
checked with the vehicle on a level sur-
face and with the engine stopped and
cold.
To check the level, proceed as follows:
– turn the ignition key to MAR;
– disconnect the breather tube and
remove the cap (A) checking that the
level corresponds with the MAXmark on
the dipstick integrated with the cap;
– if the oil is below the MAXmark, top
up to reach the correct level;Do not add oil with spec-
ifications other than that
already in the gearbox.

A0A0197b
Used gearbox oil con-
tains dangerous sub-
stances for the environ-
ment. For changing the oil we
advise contacting Alfa Romeo
Authorised Services who are
equipped for disposing of used oil
respecting nature and the law.
Be very careful working
inside the engine com-
partment if the engine is
hot: danger of burns. Remember
that the fan may cut in if the
engine is very hot: danger of
injury.
Engine oil consumption
Max engine oil consumption is usually
400 grams every 1000 km.
During the initial period of use the
engine settles, therefore engine oil con-
sumption may be considered stabilised
only after the first 5000 ÷ 6000 km.
IMPORTANTEngine oil consumption
depends on the way of driving and the
conditions of use of the vehicle.– after refitting the cap, insert the
breather tube firmly on the housing on the
cap and turn the ignition key to STOP.

The cooling system is
pressurised. If necessary,
replace the cap only with
another genuine one, otherwise
the system efficiency could be
compromised. Do not remove the
tank cap with the engine hot:
danger of burns.
The engine cooling sys-
tem uses antifreeze pro-
tective fluid PARAFLU UP.
For topping up use the same type
of fluid contained in the cooling
system. The PARAFLU UP fluid
cannot be mixed with any other
type of fluid. Should it occur,
never start the engine and contact
Alfa Romeo Authorised Services.ENGINE COOLANT FLUID
(fig. 8)
Do not remove the cap
when the engine is hot:
danger of burns.
The level of the coolant in the header
tank (reservoir) should be checked with
the engine cold and the car on a level sur-
face and it should be between the MIN
andMAXmarks on the tank.
fig. 8
A0A0240b
If the level is low, loosen the header tank
cap (A) and slowly pour a mixture of 50%
distilled water and 50% PARAFLU UP
FL Seleniathrough the filler neck until
nearing the MAXmark.
The antifreeze mixture of 50%
PARAFLU UPand 50% distilled water
guarantees protection down to –35 °C.

Oil consumption is very
low; if topping up again is
needed shortly after-
wards, have the system checked
for possible leaks by Alfa Romeo
Authorised Services.
VEHICLE MAINTENANCE

When loosening the
reservoir cap do not
allow the fluid to come
into contact with painted parts. If
it does, wash it off immediately
with water. Do not allow the power
steering fluid to touch hot
parts of the engine: it is
inflammable.

BRAKE AND HYDRAULIC
CLUTCH FLUID
(fig. 10)
Slacken the cap (A) and check that the
fluid contained in the reservoir reaches the
maximum mark.
POWER STEERING FLUID
(fig. 9)
Check that the level of the oil in the
reservoir is at maximum.
This operation should be carried out with
the vehicle on a level surface and the
engine switched off and cold.
Check that the level reaches the MAX
mark on the reservoir or coincides with the
upper notch (maximum level) on the dip-
stick (A) integral with the reservoir cap.
If the oil level in the reservoir is below
the specified one, top up only with one of
the products listed in the “Fluid and lubri-
cant Specification” table in the “Technical
Specifications” chapter proceeding as fol-
lows:– Start the engine and wait for the oil
level in the reservoir to stabilise.
– With the engine running, turn the
steering wheel lock to lock a few times.
– Top up to the MAXlevel notch, then
refit the cap.

VEHICLE MAINTENANCE
259
Do not travel with the
windscreen washer reser-
voir empty: the action of
the windscreen washer is funda-
mental for improving vision.
To avoid damaging the
pump motor, do not use the
windscreen/rearscreen
washers when the reservoir is
empty.
Some commercial addi-
tives for windscreen wash-
ers are inflammable. The
engine compartment contains hot
components which may set it on
fire.
IMPORTANTBrake and hydraulic
clutch fluid is hygroscopic (i.e. it absorbs
moisture). For this reason, if the car is
mainly used in areas with a high degree of
atmospheric humidity, the fluid should be
replaced at more frequent intervals than
specified in the Scheduled Maintenance
Programme.
WINDSCREEN/REARSCREEN
HEADLIGHT WASHER FLUID
(fig. 11)
Open the cap (A) and check the level in
the reservoir.
If necessary top up using a mixture of
water and TUTELA PROFESSIONAL
SC 35fluid as follows:
– 30% of TUTELA PROFESSIONAL
SC 35and 70% water in summer;
– 50% of TUTELA PROFESSIONAL
SC 35and 50% water in winter;
– in the case of temperatures below -
20°C use TUTELA PROFESSIONAL
SC 35fluid neat. Brake and clutch fluid is
poisonous and highly cor-
rosive. In the event of
accidental contact, wash the
parts concerned immediately with
neutral soap and water, then
rinse thoroughly. See a doctor at
once if the fluid is swallowed.
Theπsymbol on the
container indicates syn-
thetic brake fluid, distin-
guishing it from the mineral kind.
Using mineral fluids irreversibly
damages the special braking sys-
tem rubber seals.
