1983 FIAT UNO tailgate

Buying spare parts
Spare parts are available from many
sources, for example, FIAT garages, other
garages and accessory shops, and motor
factors. Our advice regarding spare parts is as
follows:
Officially appointed FIAT garages -This is
the best source of parts which are peculiar to
your car and otherwise not generally available
(eg complete cylinder heads, internal gearbox
components, badges, interior trim etc). It is
also the only place at which you should buy
parts if your vehicle is still under warranty;
non-FlAT components may invalidate the
warranty. To be sure of obtaining the correct
parts it will always be necessary to give the
partsman your car’s engine number, chassis
number and number for spares, and if
possible, to take the old part along for positive
identification. Many parts are available under
a factory exchange scheme - any parts
returned should always be clean. It obviously
makes good sense to go straight to the
specialists on your car for this type of part for
they are best equipped to supply you. They
will also be able to provide their own FIATservice manual for your car should you require
one.
Other garages and accessory shops - These
are often very good places to buy material
and components needed for the maintenance
of your car (eg oil filters, spark plugs, bulbs,
drivebelts, oils and grease, touch-up paint,
filler paste etc). They also sell accessories,
usually have convenient opening hours,
charge lower prices and can often be found
not far from home.
Motor factors - Good factors stock all of the
more important components which wear out
relatively quickly (eg clutch components,
pistons, valves, exhaust systems, brake
pipes/seals/shoes and pads etc). Motor
factors will often provide new or reconditioned
components on a part exchange basis - this
can save a considerable amount of money.
Vehicle identification
numbers
Modifications are a continuing and
unpublicised process in vehicle manufacture
quite apart from major model changes. Spareparts manuals and lists are compiled upon a
numerical basis, the individual vehicle
numbers being essential to correct identifi-
cation of the component required.
The chassis type and number plate is
located on the wing valance under the bonnet.
The identification data plate is located on the
radiator top rail. The engine type and number
is stamped on the cylinder block. The
paintwork colour code is given on a label
stuck to the inner surface of the tailgate.
