1 General description
The Uno is an all steel, welded Hatchback
of unitary construction available in three- or
five-door versions.
Various levels of trim and equipment are
available depending upon model.
Factory fitted options include a sunroof,
central door locking and electrically-operated
front windows.
2 Maintenance-
bodywork and underframe
1
The general condition of a vehicle’s
bodywork is the one thing that significantly
affects its value. Maintenance is easy, but
needs to be regular. Neglect, particularly after
minor damage, can lead quickly to further
deterioration and costly repair bills. It is
important also to keep watch on those parts
of the vehicle not immediately visible, for
instance the underside, inside all the wheel
arches, and the lower part of the engine
compartment.The basic maintenance routine for the
bodywork is washing - preferably with a lot of
water, from a hose. This will remove all the
loose solids which may have stuck to the
vehicle. It is important to flush these off in
such a way as to prevent grit from scratching
the finish. The wheel arches and underframe
need washing in the same way, to remove any
accumulated mud, which will retain moisture
and tend to encourage rust. Paradoxically
enough, the best time to clean the underframe
and wheel arches is in wet weather, when the
mud is thoroughly wet and soft. In very wet
weather, the underframe is usually cleaned of
large accumulations automatically, and this is
a good time for inspection.
Periodically, except on vehicles with a wax-
based underbody protective coating, it is a
good idea to have the whole of the
underframe of the vehicle steam-cleaned,
engine compartment included, so that a
thorough inspection can be carried out to see
what minor repairs and renovations are
necessary. Steam-cleaning is available at
many garages, and is necessary for the
removal of the accumulation of oily grime,
which sometimes is allowed to become thick
in certain areas. If steam-cleaning facilities are
not available, there are some excellent grease
solvents available which can be brush-applied; the dirt can then be simply hosed off.
Note that these methods should not be used
on vehicles with wax-based underbody
protective coating, or the coating will be
removed. Such vehicles should be inspected
annually, preferably just prior to Winter, when
the underbody should be washed down, and
any damage to the wax coating repaired.
Ideally, a completely fresh coat should be
applied. It would also be worth considering
the use of such wax-based protection for
injection into door panels, sills, box sections,
etc, as an additional safeguard against rust
damage, where such protection is not
provided by the vehicle manufacturer.
After washing paintwork, wipe off with a
chamois leather to give an unspotted clear
finish. A coat of clear protective wax polish
will give added protection against chemical
pollutants in the air. If the paintwork sheen
has dulled or oxidised, use a cleaner/polisher
combination to restore the brilliance of the
shine. This requires a little effort, but such
dulling is usually caused because regular
washing has been neglected. Care needs to
be taken with metallic paintwork, as special
non-abrasive cleaner/polisher is required to
avoid damage to the finish. Always check that
the door and ventilator opening drain holes
and pipes are completely clear, so that water

speakers, central door locking or power
operated windows, the electrical leads must be
disconnected and withdrawn through the
flexible duct before the door hinges are
unbolted. Disconnection will require removal of
the door trim panel as described in Section 11.
5It is recommended that the door is unbolted
from the hinge, leaving the hinge attached to
the body pillar.
6Refitting is a reversal of removal, but leave
the bolts finger tight until the door has been
gently closed and its alignment checked.
7The door can be moved up and down or
sideways using the travel provided by the
elongated bolt holes.
8If the door is not flush with the adjacent
body panels then shims should be inserted
under the hinges.9Adjust the striker to provide smooth
positive closure (photo).
14 Tailgate-
removal and refitting

1Open the tailgate and have an assistant
support it.
2From the upper ends of the struts, prise out
the locking wedges from the ball cups and
disconnect the struts (photo).
3Disconnect the washer tube.
4Unscrew the hinge mounting bolts from the
tailgate and lift the tailgate from the car
(photo).
5Refitting is a reversal of removal, but ifre-alignment is required, then the rear section
of the roof lining will have to be removed and
the hinge to body bolts released.
6Adjust the position of the lock striker to
provide smooth positive closure. The rubber
buffers should be screwed in or out in
conjunction with the adjustment of the striker
(photos).
7On some models, a remote control tailgate
opening release lever is fitted. Removal and
refitting of the cable is similar to that
described in Section 8 (photo).

stands outside ready to catch it.
4Clean the body flange and fit the
weatherstrip to the glass.
5Insert a length of strong cord in the body
flange groove of the weatherseal so that the
ends of the cord cross over at the centre of
the bottom run and hang out a few inches.

7With an assistant pressing on the outside of
the glass, go inside and pull the cords evenly.
This will draw the lip of the weatherseal over
the body flange and seat the glass.
8Tap the glass with the palm of the hand to
settle it.
9If the weatherseal is in good condition then
it should prove waterproof, but if there is any
doubt, apply sealant with a gun between the
rubber and the glass and the rubber and the
body flange.

1 Introduction
Since its introduction in 1983, the FIAT Uno
has had a number of modifications and
improvements including the fitting of a twin
choke carburettor, low profile tyres, tinted
windows and remotely-controlled central door
locking.
The major mechanical change was the
introduction of the FIRE (Fully Integrated
Robotised Engine) on 45 and 45S models to
be followed by a new 1108 cc “FIRE” engine
on the 60S model from 1989 on.
A 1301 cc Turbo ie engine model wasavailable for a short period. This model had a
Bosch LE2 Jetronic electronic fuel injection
(ie) and a turbocharger to give added
performance. To uprate the braking to suit,
disc brakes were fitted to the rear in place of
the original drum type brakes.
A 1372 cc engine model was introduced in
1989. Two versions were initially available. A
Bosch Mono-Jetronic single-point fuel
injection (SPi) system, as found on the 70 SX
model and Bosch L3.1 or L3.2 Jetronic
multi-point fuel injection (MPi) systems were
fitted to Turbo models. L3.2 MPi system
models were equipped with catalytic
converters, to improve exhaust emission. All
fuel injection engines are fitted with electroni-
cally controlled engine management systems.
A new style instrument panel, switchgearand a revised facia layout was introduced in
1989.
During 1992, SPi fuel systems were fitted to
the 999 cc and 1108 cc engines, along with
catalytic converters for improved exhaust
emissions.
Five speed transmissions were introduced
to 999 cc models in 1993.
It is recommended that this Supplement is
always referred to before the main Chapters
of the Manual.
Project vehicles
The vehicles used in the preparation of this
supplement, and appearing in many of the
photographic sequences were a 1986 Uno
45S FIRE, a 1988 1301 cc Uno Turbo ie and a
1991 1372 cc Uno SXie.

100Disconnect the battery negative lead.
101Remove the bonnet as described in
Chapter 12.
102Remove the wiper arm and blade as
described in Chapter 9, then unscrew and
remove the pivot nut.
103Undo the air inlet grille retaining screws
noting that two are not fitted with washers.
Where applicable, remove the washer
reservoir filler cap from the reservoir neck
protruding through the grille. Carefully prise
free and lift the air inlet grille clear of the body.
As it is lifted, invert it and detach the washer
hose from the washer nozzle.
104Syphon any remaining washer fluid from
the reservoir, then disconnect it and partiallywithdraw it from the recess in front of the
windscreen so that the wiring connection and
the washer supply hoses (to the windscreen
washer and the rear screen washer nozzles)
can be detached from the pump unit. Remove
the reservoir from the vehicle.
105Refit in the reverse order of removal. If the
washer pump unit was detached from the
reservoir, use a new seal washer when refitting
it. Top up the reservoir and check the screen
washers for satisfactory operation before
refitting the grille panel and the wiper arm/blade.
Tailgate wiper motor
(later models) -
removal and refitting
Á
106Although the tailgate wiper motor differs
in appearance, its removal and refitting
procedures are much the same as those
described for the earlier models in Section 27
of Chapter 9 (photo).
Radio
107All later models are now equipped with
power supply and speaker leads for radio
installation.
108Installation of the standard FIAT aerial
mounted on the windscreen pillar is shown
(photos).
Check control system sensors -
description
109The locations of the sensors referred to in
Chapter 9, Section 34 are given in the
following paragraphs, and their construction
differs according to their individual function.
Brake fluid level sensor
110This is mounted in the master cylinder
fluid reservoir cap, and comprises a pair of
reed switches in a glass bulb, and a magnet at
the end of a float.
111When the fluid level is correct, the
magnetic flux closes the switches. In the
event of a leak in the system, the magnet
moves away, the switches open and the
warning lamp comes on.
Brake disc pad wear sensor
112This is basically a circuit wire embedded
in the pad friction material. As the pad wears,
the wire is eventually exposed and contacts
the disc, whereupon the warning lamp comes
on to indicate that pad renewal is necessary.
Coolant level sensor
113This is located in the cooling system
expansion tank, and is of the reed switch
type, which operates in a similar way to that
described for the brake fluid sensor.
Engine oil level sensor
114This is located at the end of the dipstick,
and comprises a pair of switches at the end of a
bi-metallic strip, heated by electrical resistance.
115The heat is dissipated by the immersion
of the dipstick in the engine oil, so preventing
the bi-metallic strip from curving so much that
the switches would open.
116If the oil level drops, the heat is no longer
dissipated, the switches open, and the
warning lamp comes on.
