SPRAY JETS (fig. 15-16)
If the jet of fluid is inadequate, firstly check
that there is fluid in the reservoir: see
“Checking levels” in this chapter.
Then check that the nozzle holes are not
clogged, if necessary use a needle.
If necessary, direct the jet of fluid work-
ing on the adjustment screw (A).

Driving with worn wiper
blades is a serious hazard,
because visibility is reduced in bad
weather.

HEADLIGHT WASHERS
Regularly check that the spray jets are in-
tact and clean (fig. 17).
If it is necessary to direct the jet, contact
an Alfa Romeo Authorised Service.
BODYWORK
PROTECTION FROM
ATMOSPHERIC AGENTS
The main causes of corrosion are:
– atmospheric pollution
– salty air and humidity (coastal areas, or
hot humid climates)
– seasonal environment conditions.
Not to be underestimated is also the abra-
sive action of wind-borne atmospheric dust
and sand and mud and gravel raised by oth-
er vehicles.
On your
Alfa 147 GTA, Alfa Romeo
has implemented the best manufacturing
technologies to effectively protect the body-
work against corrosion.
These include:
– Painting products and systems which
give the vehicle particular resistance to cor-
rosion and abrasion.
– Use of galvanised (or pretreated) steel
sheets, with high resistance to corrosion.
– Spraying the underbody, engine com-
partment, wheel arches and other parts with
highly protective wax products.
fig. 17
A0A0425m
– Spraying of plastic parts, with a protec-
tive function, in the more exposed points:
underdoor, inner wheel arch linings, etc.
– Use of “open” boxed sections to pre-
vent condensation and pockets of moisture
from triggering rust inside.
VEHICLE EXTERIOR AND
UNDERBODY WARRANTY
TheAlfa 147 GTAis guaranteed
against perf oration due to rust of any orig-
inal element of the structure or body. For the
general terms of this warranty, refer to the
Warranty Booklet.

ADVICE FOR PRESERVING
THE BODYWORK
Paint
The paintwork does not only serve an aes-
thetic purpose but also protects the under-
lying sheet metal.
In the case of deep scrapes or scores, you
are advised to have the necessary touch-
ing up carried out immediately to avoid the
formation of rust.
Only original products should be used for
touching up paint (see “Body paint identi-
fication plate” in the “Technical Specifica-
tions” chapter).
Normal paint maintenance consists in
washing at intervals depending on the con-
ditions and environment of use. For exam-
ple, in highly polluted areas, or if the roads
are sprayed with salt, it is wise to wash the
car more frequently.Do not wash the vehicle after it has been
left in the sun or with the bonnet hot: this
may alter the shine of the paintwork.
Exterior plastic parts must be cleaned in
the same way as the rest of the vehicle.
Where possible, do not park under trees;
the resinous substance many species release
give the paint a dull appearance and in-
crease the possibility of triggering rust
processes.
IMPORTANTBird droppings must be
washed off immediately and thoroughly as
the acid they contain is particularly aggres-
sive.
Windows
Use specific products to clean the windows.
Use clean cloths to avoid scratching or al-
tering the transparency of the glass.
IMPORTANTThe inside of the
rearscreen should be wiped gently with a
cloth in the direction of the filaments to
avoid damaging the heating device. Detersives pollute water.
The car should therefore be
washed in areas equipped
for the collection and purification
of the liquid used in the washing
process.
To correctly wash the car:
1) Remove the aerial from the roof to pre-
vent damage to it if the car is washed in
an automatic system.
2) Spray the vehicle with a low pressure
jet of water.
3) Pass a sponge moistened with a light
detergent solution, rinsing the sponge fre-
quently.
4) Rinse well with water and dry with a
jet of air or chamois leather.
When drying, take particular care with the
less visible parts like door surrounds, bon-
net and around the headlights where wa-
ter may stagnate. The vehicle should not be
taken to a closed area immediately, but left
in the open so that residual water can evap-
orate.

CLEANING LEATHER SEATS
– Remove dried on dirt with a lightly
moistened chamois leather or cloth with-
out pressing too hard.
– Remove liquid and grease stains with
a dry absorbent cloth without rubbing. Then
wipe with a soft cloth or chamois leather
with water and neutral soap. If the stain per-
sists, use specific products, carefully follow-
ing the instructions for use.
IMPORTANTNever use alcohol. Make
sure that cleaning products do not contain
alcohol and alcohol derivatives even at low
strength.
INTERIOR PLASTIC PARTS
Use appropriate products designed to pre-
serve the appearance of components.
IMPORTANTNever use spirit or petro-
leum to clean the instrument cluster. Engine compartment
At the end of the winter the engine com-
partment should be carefully washed, with-
out directing the jet against electronic con-
trol units. Contact a specialised workshop to
have this done.
INTERIOR FITTINGS
Periodically check that water is not trapped
under the mats (due to water dripping off
shoes, umbrellas, etc.) which could cause ox-
idisation of the sheet metal.
Detergents cause water
pollution. Therefore the en-
gine compartment should
be washed in areas equipped for
collecting and purifying the liquid
used in the washing process.
IMPORTANTThe vehicle should washed
with the engine cold and the ignition key at
STOP. After washing make sure that the
various protections (e.g. rubber caps and
various covers) have not been damaged or
removed.CLEANING SEATS AND FABRIC
AND VELVET PARTS
– Use a soft brush or vacuum cleaner to
remove dust. Velvet is cleaned better if the
brush is moistened.
– Rub the seats with a sponge moistened
with a solution of water and neutral deter-
gent.
Never use inflammable
products like fuel oil ether
or rectified petrol for cleaning inside
the car. The electrostatic charges
generated when rubbing to clean
may cause fire.
WARNING
Do not keep aerosol cans in
the car. They might ex-
plode. Aerosol cans must never be
exposed to a temperature above
50°C. The temperature inside the
car exposed to the sun may go well
beyond that figure.
