thumb and forefinger at the centre of the run
between the auxiliary shaft sprocket and the
camshaft sprocket. Using this method it
should just be possible to twist the belt
through 90º using moderate pressure.
55To adjust the tension, loosen off the
tensioner pulley nut then insert two rods (or
screwdrivers) into position in the pulley holes
and position a lever between them.
56Gently lever the tensioner pulley in the
required direction to set the tension as
described, then initially tighten the pulley nut
to lock the tensioner in the required position.
57Remove the tools from the tensioner,
recheck the tension and then tighten the
tensioner pulley nut securely.
58Rotate the crankshaft clockwise through
two complete turns using a socket or spanner
on the crankshaft pulley nut, then recheck the
belt tension. To avoid the possibility of
unscrewing the pulley nut, remove the spark
plugs to enable the engine to be turned over
easier.
59If further adjustment is required, repeat
the previously mentioned procedures. If in
doubt, err on the slightly tight side when
adjusting the tension. If the belt is set too
loose, it may jump off the sprockets resulting
in serious damage.
60Remove the crankshaft pulley retaining
nut, fit the timing belt cover, then refit and
tighten the pulley nut to the specified torque
setting.
61Refit the remaining components in the
reverse order of removal. Tighten the retaining
nuts/bolts to the specified torque settings
where given. Adjust the tension of the
alternator drivebelt as described in Section 8.
Adjustment using FIAT special
tools
62Assemble the special tools and fit them to
the belt tensioner pulley as shown in
Fig. 13.16. When fitted, the tool rod must be
as vertical as possible and it is important to
note that no sliding weights must be attached
to tool No. 1860745100.
63Slacken the tensioner pulley nut, if not
already done. Rotate the crankshaft clockwise
through two complete turns using a socket or
spanner on the crankshaft pulley nut. The
special tool rod may move from the vertical asthe engine is turned over, in which case the
joint will need to be re-adjusted to return the
rod to the vertical and the operation repeated.
64With the two revolutions of the crankshaft
completed, tighten the belt tensioner pulley
nut securely and remove the special tools.
65Remove the crankshaft pulley retaining
nut, fit the timing belt cover, then refit and
tighten the pulley nut to its specified torque
setting.
66Refit the remaining components in the
reverse order of removal. Tighten the retaining
nuts/bolts to the specified torque settings
where given. Adjust the tension of the
alternator drivebelt as described in Sec-
tion 8.
Camshaft front oil seal -
renewal#
67The camshaft front oil seal may be
renewed with the engine in the vehicle, and
the camshaft in situ, as follows.
68Remove the timing belt and the camshaft
sprocket as described previously in this
Section.
69Punch or drill a small hole in the centre of
the exposed oil seal. Screw in a self-tapping
screw, and pull on the screw with pliers to
extract the seal.
70Clean the oil seal seat with a wooden or
plastic scraper.
71Lubricate the lips of the new seal with
clean engine oil, and drive it into position until
it is flush with the housing, using a suitable
socket or tube. Take care not to damage the
seal lips during fitting. Note that the seal lips
should face inwards.
72Refit the camshaft sprocket and thetiming belt as described previously in this
Section.
Camshaft, housing and
followers -
removal and refitting
#
Note: The engine must be cold when
removing the camshaft housing. Do not
remove the camshaft housing from a hot
engine. New camshaft housing and camshaft
cover gaskets must be used on refitting.
73If the engine is still in the vehicle,
disconnect the battery negative lead.
74Refer to paragraphs 3 to 7 in this part of
this Section for details and remove the
camshaft cover.
75Remove the camshaft sprocket and timing
belt as described previously in this Section.
76Remove the three securing nuts and the
single securing bolt, and withdraw the upper
section of the rear timing belt cover.
77Unscrew the camshaft housing securing
bolts. There are seven bolts which are
accessible from outside the camshaft
housing, and five shorter bolts which are
accessible from inside the housing (these
bolts are normally covered by the camshaft
cover). Note that each bolt is fitted with two
washers (photo).
78Carefully lift the camshaft housing from
the cylinder head. Be prepared for the cam
followers to drop from their bores in the
camshaft housing as the camshaft housing is
lifted, and ensure that the cam followers are
identified for position so that they can be
refitted in their original positions (this can be
achieved by placing each cam follower over
its relevant valve in the cylinder head).

Cylinder head
(1372 cc ie engine) -
removal and refitting
#
Note: The following instructions describe
cylinder head removal and refitting leaving the
camshaft, manifolds and associated items in situ
In the head. If required, these items can be
removed separately. When removing the
cylinder head the engine must be cold - do not
remove the head from a hot engine. A new
cylinder head gasket and any associated gaskets
must be used during reassembly. FIAT specify
that the main cylinder head bolts should be
renewed after they have been used (ie tightened)
four times. If in any doubt as to the number of
times that they have been used renew them as a
precaution against possible failure.
Warning: Refer to the beginning
of Section 9 before starting any
work.
102Depressurise the fuel supply system as
described in Section 9 of this Chapter.
103Disconnect the battery negative lead.
104Drain the engine coolant as described in
Section 8.
105Remove the air cleaner unit as described
in Section 9.
106Remove the timing belt as described
previously in this Section.107Disconnect the crankcase ventilation
hose from the cylinder head and the SPi
injector unit.
108Disconnect the accelerator cable at the
engine end.
109Detach the engine idle speed check
actuator lead, the inlet manifold vacuum
sensor lead, the coolant temperature sensor
lead, the injector supply lead, the throttle
position switch lead and the distributor cap
(with HT leads). Position them out of the way.
110Disconnect the brake servo hose from
the manifold.
111Disconnect the coolant hoses from the
thermostat and the inlet manifold.
112Slowly release the fuel supply and return
hose retaining clips and detach the hoses
from the injector unit housing and
connections. Catch any fuel spillage in a clean
cloth and plug the hoses to prevent the
ingress of dirt and further fuel loss.
113Unbolt and detach the exhaust downpipe
from the manifold.
114Loosen off the cylinder head retaining
bolts in a progressive manner, reversing the
sequence shown in Fig. 13.17. When all of the
bolts are loosened off, extract them and
collect the washers.
115Check that all fittings and associated
attachments are clear of the cylinder head,
then carefully lift the head from the cylinder
block. If necessary tap the head lightly with a
soft-faced mallet to free it from the block, but
do not lever it free between the joint faces.
Note that the cylinder head is located on
dowels.116Recover the old cylinder head gasket and
discard it.
117Clean the cylinder head and block mating
surfaces by careful scraping. Take care not to
damage the cylinder head - it is manufactured in
light alloy and is easily scored. Cover the coolant
passages and other openings to prevent dirt and
carbon from falling into them. Mop out all the oil
from the cylinder head bolt holes - if oil is left in
them, hydraulic pressure, caused when the bolts
are refitted, could cause the block to crack.
118If required the cylinder head can be
dismantled and overhauled as described in
paragraphs 129 to 131 of this Section.
119The new gasket must be removed from
its protective packing just before it is fitted.
Do not allow any oil or grease to come into
contact with the gasket. Commence refitting
the cylinder head by locating the new gasket
on the cylinder block so that the word “ALTO”
is facing up (photo).
120With the mating faces scrupulously
clean, refit the cylinder head into position and
engage it over the dowels. Refer to the note at
the beginning of this part of the Section, then
refit the ten main cylinder head bolts and
washers. Screw each bolt in as far as possible
by hand to start with. Do not fit the smaller
(M8 x 1.25) bolts at this stage (photos).
121The bolts must now be tightened in stages
and in the sequence shown in Fig. 13.17. Refer
to the specified torque wrench settings and
tighten all bolts to the Stage 1 torque, then
using a suitable angle gauge, tighten them to
the second stage, then the third stage (photos).

Ensure that the mating faces of the exhaust
manifold-to-downpipe are clean and fit a new
gasket when reconnecting.
124Ensure that all wiring connections are
cleanly and securely made.
125Top up the engine oil and coolant levels
as required on completion.
Cylinder head
(1372 cc Turbo ie engine)
- removal and refitting
#
126Proceed as described in paragraphs 102
to 125 above for the non-Turbo model, but
note the following differences.127The cylinder head cannot be removed
and refitted with the manifolds and
turbocharger fitted. It is therefore first
necessary to detach and remove the inlet
manifold, then the turbocharger and the
exhaust manifold as described in Section 9.
128The ignition distributor is mounted on the
side of the engine, not the rear end of the
cylinder head as on the “ie” engine. It is
therefore only necessary to disconnect the HT
leads from the spark plugs.
Cylinder head - inspection
and renovation¢
Note: Refer to a dealer for advice before
attempting to carry out valve grinding or seat
recutting operations. These operations may
not be possible for the DIY mechanic due to
the fitment of hardened valve seats for use
with unleaded petrol.129Use a straight-edge to check the cylinder
head gasket surface for distortion. If it
exceeds the specified tolerance, it must be
resurfaced by a FIAT dealer or automotive
engineer.
130Refer to Section 39 in Chapter 1 for the
general details on dismantling and renovating
operations on the cylinder head but note that
there is a spring seat and a flat washer fitted
between the cylinder head and the valve
springs (photos).

the bolts retaining the gear linkage mounting
bracket and the clutch housing lower cover
bolts. Remove the cover from the clutch
housing.
135Unscrew the sump retaining nuts and
bolts, then lower and remove the sump.
136Unscrew the timing belt rear cover
retaining bolts.
137Move the timing belt rear cover towards
the front of the car to gain access to the
retaining bolt and then unscrew and remove
the three oil seal housing retaining bolts.
Remove the crankshaft front oil seal housing.
138Note the orientation of the seal in its
housing prior to its removal. Support the
underside of the housing and carefully drive
the old oil seal from the housing using a
punch or a tubular drift of suitable diameter.
An alternative method is to punch or drill a
small hole in the face of the oil seal (but take
care not to drill into the housing) and insert a
self-tapping screw into the seal. Withdraw the
seal by gripping the screw with pliers and
pulling the seal from the housing. If necessary,
fit a second screw into the seal on the
opposite side to provide an even pull.
139Clean the mating faces of the housing
and the front of the crankcase using a suitable
scraper.
140Drive or press the new seal into positionin the housing in the reverse order of removal,
but ensure that it is correctly orientated as
noted during removal (photo).
141Refit the oil seal housing with a new
gasket and tighten the retaining bolts to the
specified torque setting (photos).
142Refit the sump as described later in this
Section using a new gasket. Tighten its
retaining nuts and bolts to the specified
torque. Refit the clutch cover and the gear
linkage mounting bracket.
143Fit the new timing belt, adjust its tension
and refit the crankshaft pulley as described
earlier in this Section.
144Reconnect the remaining components
that were detached during removal in the
reverse order and top up the engine oil level to
complete.

149Refit all disturbed components.
Flywheel - removal,
inspection and refitting#
150If not already done, remove the clutch as
described in Chapter 5.
151Prevent the flywheel from turning by
jamming the ring gear teeth, or by bolting a
strap between the flywheel and the cylinder
block.
152Make alignment marks on the flywheel
and the end of the crankshaft, so that the
flywheel can be refitted in its original position.
153Unscrew the securing bolts and remove
the washer plate, then withdraw the flywheel.
Do not drop it, it is very heavy.
154With the flywheel removed, the ring gear
can be examined for wear and damage.
155If the ring gear is badly worn or has
missing teeth it should be renewed. The old
ring gear can be removed from the flywheel by
cutting a notch between two teeth with a
hacksaw and then splitting it with a cold
chisel. Wear eye protection when doing this.
156Fitting of a new ring gear requires heating
the ring to a temperature of 80ºC (176ºF). Do
not overheat, or the hard-wearing properties
will be lost. The gear has a chamfered inner
edge which should fit against the shoulder on
the flywheel. When hot enough, place the gear
in position quickly, tapping it home ifnecessary, and let it cool naturally without
quenching in any way.
157Ensure that the mating faces are clean,
then locate the flywheel on the rear of the
crankshaft, aligning the previously made
marks on the flywheel and crankshaft.
158Fit the washer plate, and insert the
securing bolts, then prevent the flywheel from
turning as described in paragraph 151 whilst
the bolts are tightened progressively to the
specified torque setting in a diagonal
sequence (photos).
159If applicable, refit the clutch as described
in Chapter 5.
Sump -
removal and refittingÁ
160Drain the engine oil from the sump as
described in Chapter 1.
161Disconnect the lead from the engine oil
level sensor in the sump.
162Unscrew and remove the bolts retaining the
gear linkage mounting bracket (where applicable)
and the clutch housing lower cover bolts.
Remove the cover from the clutch housing.
163Unscrew and remove the sump retaining
bolts and nuts and lower the sump from the
crankcase. Recover the gasket.
164Clean all traces of old gasket from the
sump, crankcase and both oil seal housing
mating surfaces.
165Commence reassembly by applying
sealing compound (FIAT No. 5882442 orequivalent) to the joints between the
crankshaft front and rear oil seal housings and
the mating face of the crankcase (photo).
166Locate the new gasket in position on the
crankcase then fit the sump. As it is fitted it
will need to be twisted to avoid fouling the oil
pump unit. Refit the retaining bolts and nuts
and tighten them to the specified torque
(photos).
167Check that the sump drain plug is refitted
and fully tightened. If the engine is in the car,
top up the engine oil level.
Oil pump - removal,
checking and refittingª
168Drain the engine oil and remove the
sump as described in the previous
sub-Section.
169Unscrew the retaining bolts then
withdraw the oil pump and intake pipe/filter
from its location within the crankcase.
Remove the gasket.
170If oil pump wear is suspected, first check
the cost and availability of new parts and the
cost of a new pump. Then examine the pump
as described below and decide whether
renewal or repair is the best course of action.
171Unscrew the three securing bolts and
remove the oil pump cover (photo). Note that
as the cover is removed, the oil pressure relief
valve components will be released.

174The gears can now be removed from the
oil pump body. Inspect them for obvious signs
of wear or damage, and renew if necessary.
175Commence reassembly by lubricating
the gears with clean engine oil, and refitting
them to the casing. Note that the scribed
marks on the top faces of the gears should
face each other with the gears installed
(photo).
176Using a feeler gauge, check that the
clearance between the gears and the pump
body is within the limits given in the Specifica-
tions (photo).
177Using a straight-edge placed across the
top of the pump body and the gears, and a
feeler gauge, check that the gear endfloat is
within the limits given in the Specifications
(photo).
178If either the gear-to-body clearance, or
the gear endfloat is outside the specified
limits, both gears should be renewed.
179Locate the intermediate plate on the
pump body (photo).
180Place the pressure relief valve and spring
over the pressure relief hole in the
intermediate plate, and locate the spring seat
over the boss in the pump cover, then refit the
pump cover, ensuring that the pressure relief
valve components seat correctly (photos).
181Refit and tighten the pump cover
securing bolts.
182Thoroughly clean the mating faces of thepump and crankcase before refitting the
pump. Prime the pump by injecting clean
engine oil into it and turning it by hand.
183Fit the pump using a new gasket, then
insert the securing bolts and tighten them.
184Refit the sump and top up the engine oil
level.
Pistons/connecting rods -
removal and refitting#
185Remove the sump and the cylinder head
as described previously in this Section.
186The big-end caps and connecting rods
normally have identification marks stamped
into their sides, facing the coolant pump side
of the cylinder block. If no marks are present,
use a centre-punch to identify the bearing
caps and the connecting rods for location.187Turn the crankshaft so that No. 1
crankpin is at its lowest point, then unscrew
the nuts and tap off the bearing cap. Keep the
bearing shells in the cap and the connecting
rod if they are to be re-used, taping them in
position if necessary to avoid loss.
188Using the handle of a hammer, push the
piston and connecting rod up the bore and
withdraw it from the top of the cylinder block.
Loosely refit the cap to the connecting rod.
189Repeat the procedure given in
paragraphs 187 and 188 on No. 4 piston and
connecting rod, then turn the crank-
shaft through half a turn and repeat the
procedure on Nos 2 and 3 pistons and
connecting rods.

191Commence refitting as follows.
192Clean the backs of the bearing shells and
the recesses in the connecting rods and
big-end caps.
193Lubricate the cylinder bores with engine
oil.
194Fit a ring compressor to No. 1 piston, theninsert the piston and connecting rod into No. 1
cylinder. With No 1 crankpin at its lowest point,
drive the piston carefully into the cylinder with
the wooden handle of a hammer (photos).
Leave enough space between the connecting
rod and the crankshaft to allow the bearing
shell to be fitted. The piston must be fitted with
the cut-out in the piston crown on the auxiliary
shaft side of the engine, and the cylinder identi-
fication marking on the connecting rod and
big-end cap on the coolant pump side of the
engine - see Fig. 13.21.
195Slide the appropriate bearing shell into
position in the connecting rod big-end, then
pull the connecting rod firmly into position on
the crankpin (photo).
196Press the appropriate bearing shell into
position in the big-end cap (photo).
197Oil the crankpin, then fit the big-end
bearing cap with the cylinder identification
marking on the coolant pump side of the
engine, and tighten the nuts to the specified
torque setting (photos).
198Check that the crankshaft turns freely.
199Repeat the procedure in paragraphs 194
to 198 inclusive on the remaining pistons.
200Refit the cylinder head and the sump.
Pistons/connecting rods -
examination and
renovation
#
201The procedures for inspecting and
renovating the pistons and connecting rod
assemblies are in general the same as thatdescribed for the smaller engines in Sec-
tion 18 of Chapter 1. However, the following
additional points should be noted.
202When renewing a gudgeon pin, first
check the fit in the piston. It should be
possible to fit the gudgeon pin using hand
pressure, but the pin should be a tight enough
fit that it does not drop out under its own
weight. Oversize gudgeon pins are available
as spares if necessary. Use new circlips when
refitting the pistons to the connecting rods.
203Before fitting the pistons to their
connecting rods, weigh each piston and
check that their weights are all within 2.5 g of
each other. If not, the heavier pistons must be
lightened by machining metal from the
underside of the small-end bosses. This
operation must be entrusted to a FIAT dealer
or engine reconditioning specialist.
204The pistons should be fitted to the
connecting rods so that the higher, flat side of
the piston crown is on the side of the
connecting rod with the stamped cylinder
identification number, ie the gudgeon pin is
offset towards the cylinder identification
number see Fig. 13.21.
205The piston rings should be fitted with the
word “TOP” on each ring facing uppermost,
or if no marks are visible, as noted during
removal. If a stepped top compression ring is
being fitted, fit the ring with the smaller
diameter of the step uppermost. The ring end
gaps should be offset 120º from each other.
Use two or three old feeler gauges to assist

fitting, as during removal. Note that the
compression rings are brittle, and will snap if
expanded too far.
206If new pistons are to be fitted, they must
be selected from the grades available, after
measuring the cylinder bores. Normally, the
appropriate oversize pistons are supplied by
the dealer when the block is rebored.
207Whenever new piston rings are being
installed, the glaze on the original cylinder
bores should be removed using either
abrasive paper or a glaze-removing tool in an
electric drill. If abrasive paper is used, use
strokes at 60º to the bore centre-line, to
create a cross-hatching effect.
Engine/transmission
mountings - renewalÁ
208The engine/gearbox assembly is
suspended in the engine compartment on
three mountings, two of which are attached to
the gearbox, and one to the engine.
Right-hand mounting
209Apply the handbrake, then jack up the
front of the vehicle and support it securely on
axle stands.
210Suitable lifting tackle must now be
attached to the engine in order to support it as
the engine mounting is removed. No lifting
brackets are provided, so care must be taken
when deciding on an engine lifting point. In the
workshop, a right-angled bracket was made up
by bending a suitable piece of steel plate. The
bracket was then bolted to the engine using the
rear right-hand camshaft housing securing bolt
with suitable packing washers.
211Attach the lifting tackle to the bracket on
the engine and just take the weight of the
assembly.
212Working under the vehicle, unbolt the
engine mounting bracket from the cylinder
block, and unbolt the mounting from the
body, then withdraw the bracket/mounting
assembly.
213Unscrew the nut and through-bolt,
counter holding the bolt with a second
spanner or socket, and separate the mounting
from the bracket.

Warning: Refer to the beginning
of Section 9 before starting any
work.
2Depressurize the fuel system as described
in Section 9 of this Chapter.
3Disconnect the battery negative lead.
4Mark the position of the hinges on the
underside of the bonnet, then with the aid of
an assistant, unscrew the hinge bolts and lift
the bonnet clear of the car. Store the bonnet
in a safe area.
5Drain the engine coolant.
6Drain the engine and transmission oils.
7Disconnect and remove the air filter.
8Disconnect the coolant hoses from the
engine, including the hose to the inlet
manifold.
9Detach the ignition coil (HT) lead from the
distributor.10Compress the retaining clip and detach
the engine idle speed actuator lead from the
SPi unit (photo).
11Disconnect the brake servo vacuum pipe
from its connector on the inlet manifold.
12Disconnect the throttle cable from the SPi
unit.
13Disconnect the engine speed sensor lead.
14Release and detach the reversing light
lead from the switch on the transmission
(photo).
15Before disconnecting the hydraulic hose
from the clutch slave cylinder, remove the
filler cap from the reservoir and place a piece
of polythene sheet over the filler neck, then
refit the cap; this will help prevent excess fluid
loss. Once disconnected, plug the hose and
its cylinder connection to prevent the ingress
of dirt into the hydraulic system.
16Disconnect the wiring connector from the
alternator.
17Position a clean rag under the fuel supply
and return hose connections to the SPi unit,
then slowly unscrew the hose clips to release
the system pressure; catch fuel leakage in the
rag and dispose of it safely. Detach the hoses
and plug them to prevent ingress of dirt and
any further fuel leakage. Position the hoses
out of the way.
18Detach the wiring connector from the
engine coolant temperature sender unit
(photo).
19Release the retaining clip and detach the
wiring connector from the throttle position
switch. Also detach the associated earth
leads from the cylinder head.
