Any attempt to clean
the air cleaner may
cause serious engine
damage.
If they are not carried
out correctly and with
the due precautions, the
operations involving cleaner re-
placement described herein may
compromise the safety of the
car. This operation should be car-
ried out by Alfa Romeo Autho-
rized Services.
AIR CLEANER
The air cleaner is connected to the tem-
perature and air flow sensors which send
the electrical signals needed for correct
operation of the injection and ignition sys-
tem to the control unit.
It must therefore always be in perfect
conditions to ensure correct operation of
the engine, low consumption and exhaust
emission levels.When the car is habitu-
ally driven in dusty ar-
eas, the cleaner should
be changed at shorter intervals
than those given in the Pro-
grammed Maintenance Schedule.
IMPORTANT When topping up use
the special detergents available in the
shops ensuring that they contain antis-
cale and antifreeze properties.
If in doubt contact Alfa Romeo Autho-
rized Services who will be able to recom-
mend the most suitable products.
Do not travel with the
windscreen washer
reservoir empty: the action of the
windscreen washer is fundamental
for improving vision.
