WHEELS
AND TYRES
TYRES PRESSURE
Every two weeks and before long
journeys, check the pressure of each
tyre including the spare.
The pressure must be checked when
the tyre is rested and cold.
It is normal for the pressure to rise
when you are driving. If you have to
check or restore the pressure when
the tyres are warm remember that the
pressure value must be 0.3 bar above
the specified value.
SPARK PLUGS
The cleanness and soundness of the
spark plugs fig. 9are very important
for keeping the engine efficient and
polluting emissions down.
The appearance of the spark plug, if
examined by an expert eye, is a good
way of pin-pointing a malfunction even
if it has nothing to do with the ignition
system. Therefore, if the engine has
problems, it is important to have the
spark plugs checked at a Fiat Deal-
ership.The spark plugs must be
changed at the times
specified in the Service
Schedule. Only use the type of
plugs indicated: if the heat ratio
is less than required or the life
specified is not guaranteed, prob-
lems can arise.

holding.
WARNING

Windows
Use specific window cleaners to
clean the windows. Use very clean
cloths to avoid scratching the glass or
damaging its transparency.
Engine compartment
At the end of each winter season,
carefully clean the engine compart-
ment. Have this done at a garage.Detergents pollute wa-
ter. The car must there-
fore be washed in an area
equipped for the collection and
purification of the liquids used
while washing.
IMPORTANTThe car should be
washed while the engine is cold and
with the ignition key at STOP. After
washing the car, make sure that the
various protections (e.g. rubber boots
and various guards) have not been re-
moved or damaged. Outside plastic parts must be cleaned
following the usual car washing pro-
cedure.
Avoid parking your car under trees;
the resinous substances that often
drop will dull the paintwork and in-
crease the possibility of corrosion.
IMPORTANT Bird droppings must
be washed off immediately and with
great care as their acid is particularly
aggressive.

TECHNICAL SPECIFICATIONS
Motor and engineering enthusiasts as well as those
“in the trade” will probably start reading from this point
in the manual. This, in fact, is where a section jam-
packed with facts, figures, formulae, measurements and
tables begins. In a sense it is the Fiat barchetta’s iden-
tity card. A document that introduces the car and ex-
plains in technical jargon all the features that go together
to make the Fiat barchetta a model designed to give you
superlative driving satisfaction.IDENTIFICATION DATA ................................................ 136

FUEL SUPPLY/IGNITION
Integrated electronic injection and ig-
nition system: a single electronic con-
trol unit controls both functions. It
processes both the time the injection
lasts (for fuel metering) and the igni-
tion’s advance angle.
Type: Sequential in phase Multipoint
Air cleaner: dry-type with paper fil-
ter element; thermostatically con-
trolled intake.
Petrol pump: in-tank.
Injection pressure: 3 bar
Method of measuring the amount of
aspirated air by directly measuring the
maximum rate of flow with a hot wire
air flow meter.
“Closed loop” petrol metering (in-
formation about combustion provid-
ed by the Lambda sensor).Firing order: 1-3-4-2
Spark plugs:
– Champion RC10YCC
– NGK BKR6EZLUBRICATION
Forced-fed with gear pump with
pressure relief valve incorporated.
Oil purification by means of full-flow-
cartridge filter.
COOLING
Cooling system with radiator, cen-
trifugal pump and expansion tank.
“Controlled” by-pass type thermo-
stat on the secondary circuit for the
recirculation of water from the engine
to the radiator.
Electric fan for radiator cooling with
thermostatically-controlled on/off
switch on the radiator.
Modifications or repairs to
the fuel feed system that
are not carried out properly or do
not take the system’s technical
specifications into account can
cause malfunctions with the risk of
fire.
