FIAT UNO 1983 Service Repair Manual

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disconnected and withdrawn through the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
1
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).
15 Windscreen glass-
removal and refitting
5
1Remove the interior rear view mirror, the tax
disc and the wiper blade and arm.
2If the glass is intact, go inside the car and
pull the lip of the weatherseal downwards off
the body metal all along the top edge.
3Push the glass outwards while an assistant
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.
6Brush soapy water onto the edge of the
body flange and then offer the glass to the

body so that the bottom edge of the rubber
seal engages over the metal flange.
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.
10Refit the mirror, tax disc and wiper.
16 Tailgate glass-
removal and refitting

1The operations are very similar to those
described for the windscreen, but disconnect
the leads from the heater element terminals.

1The operations are similar to those
described for the windscreen in Section 15.
18 Opening side window
(three-door)-
removal and refitting
1
1Have an assistant support the glass and
then extract the screws from the hinges and
the toggle type fastener.
2Swivel the glass outwards and downwards
to remove it.
3Refitting is a reversal of removal.
19 Front seat-
removal and refitting
1
1Unbolt the seat front anchorage clamps
(photo).
2Slide the seat fully rearwards out of its
guide rails, but bend the end of the seatadjustment lever so that it passes over its
stop.
20 Rear seat-
removal and refitting
1
1The rear seat may be of one piece design or
split (60/40) depending upon the model.
2Either type of seat is easily removable once
the hinge bolts have been unscrewed and
removed (photo).
21 Centre console-
removal and refitting
1
1Pull the small black knobs from the heater
control levers.
2Extract the screws from both sides of the
heater control panel, remove the panel. As the
panel is withdrawn, disconnect the leads from
the cigar lighter and take care not to damage
the fibre optics.
3From inside the glove box, prise out the lid
stop block. Insert a screwdriver in the hole left
by its removal and unscrew the console fixing
screw (photo).

22 Facia panel-
removal and refitting
1
1Remove the instrument panel as described
in Chapter 9.
2Remove the steering wheel (Chapter 10). 3Disconnect the choke control lever and
cable from the facia panel as described in
Chapter 3.
4Remove the screws arrowed in Fig. 12.19.
5Remove the facia fixing screws, their
locations on the facia are shown in Fig. 12.20.
Screw (3) is inside the glove box (photos).
6Release the facia from the upper clips and
withdraw it.
7Refitting is a reversal of removal.23 Seat belts
1
1Seat belts are fitted as standard equipment
to both the front and rear seats.
2Regularly inspect the belts for fraying and if
evident, renew the belt.
3The front belt reel may be unbolted if the
seat is pushed fully forward and the reel cover
panel removed (photo).
4The rear belt reels are located at each side
of the luggage area (photo).
5When removing or refitting a belt from its
anchorage point, it is essential to maintain the
original fitted sequence of spacer, washer and
wave washer otherwise the belt anchor plate
will not swivel (photo).

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.
