10Apply suitable sealant to the threads of
the drain plug, then refit and tighten the plug.
11Dispose of the drained coolant safely, or
keep it in a covered container if it is to be
re-used.
12If required, the system can be flushed
through as described in Section 2 of Chap-
ter 2.
13Before attempting to refill the cooling
system, make sure that all hoses have been
reconnected, that the hoses and clips are in
good condition, and that the clips are tight.
Also ensure that the cylinder block drain plug
has been refitted and tightened. Note that an
antifreeze mixture must be used all year round
to prevent corrosion of the engine
components - refer to Section 3, Chapter 2.
14Open the bleed screw in the top of the
expansion tank (photo).
15Remove the expansion tank cap, and fill
the system by slowly pouring the coolant into
the expansion tank to prevent air locks from
forming.
16Top up the coolant until liquid free from air
bubbles emerges from the radiator bleed
screw orifice, then close the bleed screw.
17Continue topping up until the coolant
reaches the Maximum mark on the expansion
tank.
18Start the engine and run it until it reaches
normal operating temperature, then stop the
engine and allow it to cool. Normal operating
temperature is reached when the cooling fancuts into operation. Feel the radiator top hose
to ensure that it is hot. If cool, it indicates an
air lock in the system.
19Check for leaks, particularly around
disturbed components. Check the coolant
level in the expansion tank, and top up if
necessary. Note that the system must be cold
before an accurate level is indicated. There is
a risk of scalding if the expansion tank cap is
removed whilst the system is hot.
Radiator (and cooling fan)
- removal and refitting Á
20Disconnect the battery negative lead.
21Detach the wiring connectors from the
cooling fan and the fan switch located in the
radiator (photos).
22If preferred, the cooling fan unit can be
removed separately from the radiator, by
undoing the attachment bolts and carefully
withdrawing the unit upwards from the
vehicle. Take care not to damage the radiator
core as it is lifted clear (photo).
23Drain the cooling system as described
earlier in this part of the Section, but note that
it will not be necessary to remove the cylinder
block drain plug.
24Undo the retaining screws and remove
the front grille panel.
25Loosen off the retaining clips and detach
the upper coolant hose and the expansion
hose from the radiator.26Note their direction of fitting, then prise
free the radiator retaining clips. Carefully lift
the radiator from the car.
27Refitting is a reversal of the removal
procedure. Ensure that as the radiator is
lowered into position, it engages in the two
rubber location grommets.
28With the radiator (and cooling fan) refitted,
top up the cooling system as described earlier
in this Section (photo).
Thermostat -
removal and refitting Á
Note: A new thermostat cover gasket must be
used on refitting.
29Drain the cooling system as described
earlier in this Section, but note that there is no
need to drain the cylinder block.
30Disconnect the coolant hoses from the
thermostat cover (situated at the gearbox end
of the cylinder head).
31Unscrew the two thermostat cover
securing bolts, noting that the left-hand bolt
may also secure the HT lead bracket, and
remove the thermostat/cover assembly.
Recover the gasket (photo).
32If faulty, the thermostat must be renewed
complete with the housing as an assembly.
33If desired the thermostat can be tested as
described in Chapter 2.

removal and refittingÁ
Note: A new coolant pump gasket must be
used on refitting. If the pump is found to be
worn it must be renewed as a complete unit as
dismantling and repair is not possible.
37Disconnect the battery negative lead.
38Drain the cooling system as described
earlier in this Section.
39Remove the coolant/alternator drivebelt
as described in the next sub-Section.
40Unscrew the four coolant pump securing
bolts, noting that two of the bolts also secure
the alternator adjuster bracket, and withdraw
the pump from the housing (photo). Recover
the gasket.

Coolant pump/alternator
drivebelt - checking,
renewal and tensioning
Á
45At the intervals specified in Section 3 or
“Routine maintenance” at the beginning of
this manual (as applicable), the drivebelt
should be checked and if necessary
re-tensioned.
46Access to the drivebelt is made from the
underside of the car on the right-hand side.
Loosen off the front right-hand roadwheel
retaining bolts, then raise and support the car
on axle stands at the front. Remove the front
roadwheel on the right-hand side.
47Remove the underwing shield from the
right-hand wheel arch by drifting the
compression pins out from the retaining
clips. Prise free the clips and remove the
shield.
48Additional, though somewhat restricted,
access can be obtained from above by
removing the air cleaner unit on the non-Turbo
ie-engine (photo).
49Check the full length of the drivebelt for
cracks and deterioration. It will be necessary
to turn the engine in order to check the
portions of the drivebelt in contact with the
pulleys. If a drivebelt is unserviceable, renew it
as follows (photo).
50Loosen the alternator mounting and
adjuster nuts and bolts and pivot the
alternator towards the cylinder block.51Slip the drivebelt from the alternator,
coolant pump and crankshaft pulleys.
52Fit the new drivebelt around the pulleys,
then lever the alternator away from the
cylinder block until the specified belt tension
is achieved. Lever the alternator using a
wooden or plastic lever at the pulley end to
prevent damage. It is helpful to partially
tighten the adjuster nut before tensioning the
drivebelt (photo).
53When the specified tension has been
achieved, tighten the mounting and adjuster
nuts and bolts (photo).

9 Fuel and exhaust systems
Warning: Many of the
procedures in this Section
require the removal of fuel lines
and connections that may result
in some fuel spillage. Before carrying out
any operation on the fuel system refer to
the precautions given in ‘Safety first!’ at
the beginning of this Manual and follow
them implicitly. Petrol is a highly
dangerous and volatile liquid, and the
precautions necessary when handling it
cannot be overstressed.
Caution: On fuel injection
models, the system is
pressurised, therefore extra
care must be taken when
disconnecting fuel lines. When
disconnecting a fuel line union, loosen the
union slowly, to avoid a sudden release of
pressure that may cause fuel to spray out
and have a container and cloth ready to
catch spillages. Fuel pressure checking
must be entrusted to a Fiat dealer, or other
specialist, who has the necessary special
equipment.
PART A: GENERAL
Unleaded fuel
Note: On models with catalytic convertersonly unleaded petrol must be used - the use
of leaded petrol will destroy the catalyst.
1It is possible to use unleaded fuel (minimum
95 RON) in the following models with the
indicated serial numbers.
Engine Serial number
903 cc 146A.000
146A.046
146A.048
999 cc 156A2.00
1108 cc 160A3.000
1116 cc 138B.000
138B.046
146A4000
146A4.048

146A2.000
1372 cc 146C1.000
146A8.000
160A1.046
2On all except the 903 cc engine, the use of
unleaded fuel is conditional upon the
avoidance of constant high speeds and
sudden acceleration.
Air cleaner - modified types
3The air cleaner on later models is of the
automatic temperature controlled type. The
need to move the intake control lever to winter
or summer positions is no longer required.
4The air cleaner on the 999 cc engine is ofrectangular shape and the element is
removed for renewal after prising back the
toggle type clips (photos).
5To remove this type of air cleaner,
disconnect the cold and hot air intake hoses
and the large and small breather hoses
(photos).
6Unscrew the nut from the upper casing
section and then release the lower toggle type
clip and lift the air cleaner from the carburettor
(photo). Note the sealing ring between the air
cleaner and the carburettor. Unless the ring is
in good condition, renew it.
7If the thermostatically-controlled cold air
flap opener in the air cleaner casing is faulty
(checked by holding a mirror against the cold
air intake when the engine is warm), renew the
opener (single fixing screw); no repair is
possible (photo).

8The air cleaner on the 1116 cc and
1299/1301 cc engine is of circular type.
Access to the element is obtained by
extracting the three cover nuts and lifting off
the lid (photos).9The air cleaner casing can be removed after
unscrewing the four nuts which hold it to the
carburettor and the single nut on the camshaft
cover bracket. As the casing is withdrawn,
disconnect the hoses from it (photos).10The thermostatically-controlled cold air
flap opener is similar to that described in
paragraph 7.
11The air cleaner on the 1372 cc ie engine is
of rectangular shape. The element can be
removed after releasing the spring clips at the
front of the unit, followed by the two screws
from its top face. The air cleaner end cover
can then be withdrawn and the element
removed. The air cleaner unit on the 1372 cc
Turbo ie engine is located in the front
right-hand corner of the engine compartment.
Prise free the four clips to release the top
cover and expose the element.

12The fuel pump is mechanically-operated
via a pushrod which is in contact with an
eccentric cam on the camshaft. The pump is
of sealed, disposable type - no repair or
cleaning being possible.
13To remove the pump, disconnect the
flexible hoses and unbolt the pump from the
cylinder head. Retain the pushrod and the
insulator block.
14Refitting is a reversal of removal, use new
gaskets, one on each side of the insulator
block.

PART B:
CARBURETTOR MODELS
Carburettor (Weber 32 TLF) -
description
Warning: Refer to the beginning
of this Section before starting
any work.
1This carburettor is used on the 999 cc
engine and is of the single venturi
downdraught type, with a manually-operated
choke (cold start).
2The unit incorporates an automatic
anti-flooding device, a full power valve and an
accelerator pump (photos).
3The throttle valve block, although
incorporating coolant hose stubs, is not in fact
coolant-heated.4A solenoid-operated idle cut-off valve is
fitted to prevent running-on (dieseling) when
the ignition is switched off.
Carburettor (Weber 32 TLF) -
idle speed and mixture
adjustment
¢
5If the car is not equipped with a rev counter,
connect one in accordance with the
manufacturer’s instructions.
6Have the engine at normal operating
temperature and idling. Turn the idle speed
screw on the carburettor until the speed
matches that specified (photo).
7The idle mixture is set in production, and
the adjustment screw is sealed with a
tamperproof cap. If, however, the idling is not
smooth or the engine or carburettor havebeen extensively overhauled, the mixture may
require adjusting.
8Prise out the tamperproof plug and connect
an exhaust gas analyser to the car in
accordance with the instrument
manufacturer’s instructions (photo).
9With the engine at normal operating
temperature and idling at the specified speed,
turn the mixture screw until the CO
percentage is within the specified tolerance
(photo).
10If an exhaust gas analyser is not available,
turn the mixture screw anti-clockwise to
obtain maximum idle speed and then turn it
clockwise until the speed just starts to drop.
Re-adjust the idle speed screw to bring the
idle speed to the specified level.
11Switch off the engine and remove the test
instruments. It is advisable to fit a new
tamperproof cap to the mixture screw if it is
intended to take the vehicle overseas. This is
required to meet legislation in certain
countries.
Carburettor (Weber 32 TLF)
- removal and refitting ª
12Remove the air cleaner.
13Release the clips and disconnect the fuel
hoses from the carburettor. Take extreme
care that fuel spillage is contained and that
there are no naked flames in the vicinity of the
work area. Do not smoke.
14Disconnect the distributor vacuum hose
from the carburettor.

16Slacken the throttle cable by releasing the
locknut and turning the adjuster sleeve, then
slip the cable nipple out of the notch in the
throttle spindle quadrant.
17Disconnect the lead from the idle cut-off
solenoid valve.
18Unscrew the two long mounting bolts and
lift the carburettor from the inlet manifold
(photo).
19Refitting is a reversal of removal, but
observe the following points (photo).
a) Use a new flange gasket at each side of
the insulator block.
b) Check that the choke cable is fitted so
that full choke can be obtained but the
choke is fully off when the choke control
lever is pushed right in.
c) Adjust the throttle cable so that there is
just a slight amount of slackness when the
accelerator pedal is released, but when
fully depressed, full throttle can be
obtained (throttle valve plate quadrant up
against its stop).
Carburettor (Weber 32
TLF) - overhaul¢
20It is rare for a carburettor to require
complete overhaul and if the unit has seen
considerable service and wear is detected in
the throttle valve spindle bushes, it is
recommended that a new or rebuilt carburet-
tor is obtained.21Normally, the following operations are all
that will be required to keep the carburettor
working perfectly. The unit need not be
removed from the manifold unless the throttle
block is to be detached; simply remove the air
cleaner.
22Periodically, unscrew the large hexagonal
plug adjacent to the fuel inlet pipe, extract the
filter and clean it. Refit the filter and plug
(photo).
23Obtain a repair kit for your carburettor
which will contain all the necessary
replacement gaskets and seals. Extract the top
cover and choke diaphragm assembly fixing
screws, remove the small plastic cover and
push out the bush, then lift the top cover from
the carburettor. Discard the gasket (photos).24Mop out fuel and sediment from the float
chamber.
25The various jets and calibrated bleeds can
then be removed and cleared by blowing
them through with air from a tyre pump. Do
not attempt to clear them by probing with
wire, as this will ruin the calibration.
26Check the tightness of the fuel inlet
needle valve. If necessary, remove the float
and its pivot pin so that a close-fitting ring
spanner can be used on the valve body. Take
care to support the pivot pin pedestals as the
pin is tapped out - they are brittle. The throttle
valve plate block can be removed after
extracting the screws (photos).
27As reassembly progresses, carry out the
following checks and adjustments.

Float level - checking and adjustment
28With the carburettor top cover held
vertically so that the float arm just touches the
fuel inlet needle valve ball, measure between
the float and the surface of the flange gasket
as shown in Fig. 13.36. If the dimension is not
within the specified tolerance, bend the float
tab which bears on the needle valve ball.
Fast idle - adjustment (requires
removal of the carburettor)
29Close the choke valve plate by moving the
control lever fully. Retain the lever in this
position with a rubber band.
30The throttle valve plate should now be
open to give a gap between its edge and the
progression holes as specified. Check the gap
using a twist drill of equivalent diameter.
31If adjustment is required, release the
locknut and turn the adjustment screw.
Retighten the locknut.
Automatic anti-flooding device -
adjustment
32Operate the choke valve plate lever fully.
33Move the control lever on the automatic
anti-flooding device downwards to simulate
vacuum pull-down. The choke butterfly
should open, leaving a gap (B - Fig 13.38) as
specified. Measure the gap with a twist drill of
equivalent diameter and make sure that the
choke valve plate is in the position shown. If
adjustment is required, turn the screw on the
diaphragm unit.
Carburettor
(Weber 30/32 DMTE) - general
34The carburettor is of twin barrel
downdraught type with a manually-operated
choke and an electronic fuel cut-off overrun
valve (photos).
35Periodically, remove the large hexagonal
plug from its location at the fuel inlet pipe
stubs, and clean any dirt from the filter gauge.
