Job 8. Automatic gear selector
control cable - replacement.
• Step 4:
Release the
outer cable
centring bush
from its
housing in the
gearbox.
• Step 5: H INSIDE INFORMATION! To
do this, you will have to make a simple
tool as shown here. There is no FIAT
'special tool'
-
each dealer has to make
this one himself! Use the tool to push
lightly upwards, so that the cable
centring bush (illustration Job
6-4

arrowed) comes out of its seat. B
• Step 6: Fit the new cable in the reverse
order. Use a new gasket when refitting the
sump.
IMPORTANT NOTE: Readjust the cables if
necessary. See Jobs 7 and 8.
Q Step 7: Refill the transmission with
automatic transmission fluid. See Chapter
3,
Facts and
Figures.
Job 7. Kickdown cable (automatic
transmission) - adjustment.
Refer to the illustrations in Job 6.
Q Step 1: Check that the slow running speed is correct and
the accelerator cable is correctly adjusted, with just a small
amount of slack.
Q Step 2: Disconnect the kickdown cable from the idler
pulley and ensure that it is perfectly free in its operation.
• Step 3: With the selector lever in 'P', start the engine and
let it idle.
Q Step 4: Pull the inner cable by hand until resistance is felt,
caused by the compression of the valves. The cable end should
now line up with its locating slot in the idler pulley
-
if not,
adjust nuts (7) and (8).
[_l Step 5: Reconnect the cable and then switch off the
engine.
• Step 6: Check that when the accelerator pedal is hard
down, there is
1
mm of further movement left on the
kickdown cable, otherwise, make further adjustments on nuts
(7) and (8).
Refer to illustration Job 6, Step 3.
• Step 1: Raise the car and support it securely on axle stands.
• Step 2: Remove the cover from the gear selection
mechanism and familiarise yourself with the drawing referred
to here.
Q Step 3: Manually select the 'P' (park) position, using the
lever beneath the gearchange (see illustration Job
6-3,
part
6).

• Step 4: Disconnect the cable from the selector eyelet (3)
and detach from the slot in the front end of the bracket (5).
Q Step 5: Disconnect the inner cable from the gearlever (6)
and release the outer casing from its gearbox mounted
bracket (7). Remove the cable.
Q Step 6: Ensure that 'P' (park) is still engaged by moving
the gearlever (6
-
beneath the car) fully rearward.
IMPORTANT NOTE: When 'Park' is properly engaged you
will not be able to turn both front wheels in the same
direction at the same time. This is because the trans-
mission should be 'locked' when 'park' is engaged.
• Step 7: Connect the new cable at the bracket (7) and
then at the bottom of the gear lever (6).
• Step 8: Feed the other end of the cable through to the
inside of the car and fix the outer casing into the slot in
bracket (5).
• Step 9: Put the interior selector lever (2) in the 'P' (park)
position and with the inner cable taut, check that the eyelet
(3) aligns perfectly with the selector pin.
• Step 10: If necessary, slacken the adjustment nut (4) and
adjust the position of the eyelet (3) accordingly. Fit the eyelet
to the pin and tighten the nut (4).
• Step 11: Check that the gears engage in their correct
positions on the selector indicator.

qp- TRANSMISSION SELECTION
EL
-
• Now that you have completed the
installation, and BEFORE USING THE
VEHICLE ON THE ROAD, carry out the
following check:
• The engine should only start when you have selected
either 'P' (park), or 'N' (neutral).
• The gear lever selector positions should agree with
those indicated on the display panel.
• When 'R' (reverse) is selected, the reverse light
should come on. With the ignition switched off, the
buzzer should sound if any position other than 'P'
(park) is selected.
Q Step 12: Refit the selection mechanism cover.

vibration damper f
-
outer gaiter
g - circlip h - outer u.j. i - hub mounting spline
• Step 1: Note the arrangement of the inner spider joint
and drive-shaft components.
Q Step 2: Remove the
drive-shaft from the car. See
Job 9.
• Step 3: Remove the
circlip and pull or press the
spider joint from the drive-
shaft.
• Step 4: Remove the inner gaiter (illustration Job
11-1,

part c) from the seal bearing (Job
11-1,
partd). Check the
bearing for wear and smooth operation.
Q Step 5: Replace it if necessary by using a standard type
puller to remove it from the shaft, driving the new one into
position with a suitable length of tubing.
Q Step 6: After obtaining a new spider joint, if necessary,
(available as a complete replacement item from your FIAT
dealership), fit the new gaiter and its retainer to the shaft,
followed by the spider joint and circlip. No lubrication is
required prior to refitting the drive-shaft.
• Step 7: E9 INSIDE INFORMATION! The turbo diesel
uses an inboard CV joint similar to the outer one except
that it has a flange for attachment to the transmission.
(See PART A: ENGINE, Job 18, Step 16A ) Inspect and
replace in the same way as the outer one. The interme-
diate shaft can only be inspected for wear in its bearing
which cannot be removed separately. Therefore, the
whole unit must be changed if defects are found. Q
Job 12. Drive-shaft damper -
replacement.
Refer to Job
11,
Step 1
Q Step 1: A damper is fitted to the right-hand drive-shaft to
prevent vibration in what is a long drive-shaft. The rubber
mounting can disintegrate or become damaged.
Q Step 2: Use an Allen key to separate the two halves of
the weight.

gently

on the stub axle and at
the

same time tap lightly (so you don't damage the
thread) on the end of the shaft to knock it through.
• Retrieve the stub axle/hub assembly.
Q Step 7: Use a large vice or a press to push the hub out of
the stub axle.
• Step 8: You may have to remove the bearing inner track
from the hub if it comes out with it.
• Step 2: Partly dismantle the front suspension as described
in Job 9. Steps 2 to 6.
• Step 3: Unbolt the brake caliper and support bracket and
tie it clear.
• Step 1: Take note of the components illustrated here.
Also, see PART G: STEERING AND SUSPENSION, Job
12

where this work is described in more detail.
Q Step 4: Unbolt the brake disc and shield.
• Step 5: Undo the track control arm to stub axle pinch
bolt and
withdraw the
balljoint pin from
the stub axle.

Job 17. Diesel engines - Glow
plugs, checking and replacement.
LI Step 1: Disconnect the battery earth lead. Undo the
retaining nut at each plug top (a) and remove the bridging
strip (b) from between the glow plugs (complete glow plug -
inset).
• Step 2: With the
wire or connecting strap
removed, unscrew each
plug from the cylinder
head by just a couple of
turns using a ring spanner
(as shown) or socket.
H INSIDE INFORMATION: It is false economy to renew
only one glow plug at a time
-
we recommend a
complete set of new plugs if any one plug is in poor
condition. E9
• Step 6: Refit the glow plugs and tighten to their specified
torque
-
see Chapter 3, Facts and Figures. Over tightening a
glow plug can damage it!
• Step 7: Refit the bridging strip and connect the supply
lead.
17-1
PART B: WINDOW CONTROLS
Q Step B1: Disconnect the battery earth terminal.
Q Step B2: Undo the screw and remove the armrest trim,
then undo the screws fixing the armrest and withdraw it
enough to unplug the wiring. See PARTI: BODYWORK AND
INTERIOR.
• Step 3: Clean away
dirt from around the
plugs, then fully unscrew
and remove them. It's a
good idea to blank off
the plug hole with cloth
to prevent dirt from
entering.
• Step 4: Examine the condition of each plug by wiping
soot away and examining for erosion of the element sheath.
• Step 5: Check the internal resistance of each glow plug
by connecting across a resistance meter. You are looking for a
resistance of 5 ohms or less. If the reading is much higher
than this, or is infinity, the plug must be renewed.
Q Step B4: Refit in the reverse order.
PART C: COURTESY LIGHT/WINDOW LIFT INTERLOCK
SWITCHES
Q Step C3: Refit in reverse order.
PART D: WINDOW OPERATING MOTOR
Q Step D1: The motors are an integral part of the winding
mechanism and therefore can only be changed as a complete
assembly. Refer to PART I: BODYWORK AND INTERIOR
Q Step B3: From inside the armrest, undo the retaining

screws and
detach the control panel from the armrest.
G Step C1: Disconnect the battery earth lead.
Q Step C2: Take off the rubber dust cover (3), prise the
switch out of the panel and disconnect the wire.

• Step 22: Inspect the timing belt and if
-

• it is contaminated with any liquid,
• has damaged teeth,
• or frayed edges,
• or it has covered more than 30000 km,

-
fit a new one.
D INSIDE INFORMATION: Some FIAT mechanics
recommend that the belt is replaced as a matter of
course. The cost of a new belt compared to the cost
of a damaged engine, makes it a false economy not to
do so.
E9

Q Step 23: Place the timing belt over the sprockets,
keeping it tight on the run between the pump and camshaft.
Q Step 24: Push the adjusting pulley into the belt and nip
up the lock nut. Without the aid of the special tool, the
adjustment is roughly correct when you can twist the belt at
its longest point between thumb and finger through a quarter
turn (90 degrees).
• Step 25: Turn the engine two full revolutions, re-check
the timing and belt tension. Adjust if necessary and tighten
the adjusting pulley lock nut.
B INSIDE INFORMATION! CHECKING INJECTION
ADVANCE. This cannot be done without the use of a dial
gauge and special adapter to fit on the rear of the
pump. We strongly recommend that although your
engine may seem to be running well, you get it checked
by your FIAT dealer. B
Job 17. Diesel injectors -
remove and refit.
Q Step 1: Clean thoroughly around each injector to prevent
dirt from entering the cylinders when removing the injectors.
Q Step 2: Unscrew the fuel pipe union at the injector, using
a flare nut wrench (split ring spanner).
• Step 3: Loosen the union at the injection-pump-end of
each injector pipe. Disconnect the fuel-return unions at the
injector and move the return pipes away.
• Step 4:
Unscrew the
injector using a
deep 27 mm A/F
socket, or,
preferably, a
proper injector
socket
(arrowed).
Collect the
injector and its
base washer. All seals should be renewed every time the
injector is removed.
• Step 5:
Thoroughly clean
the injector
before refitting,
as dirt here can
cause cylinder
leakage, as can
the re-use of a
sealing washer,
so always renew
them.
• Step 6:
Injector efficiency
and spray pattern
can only be
checked by your
FIAT dealer, or a
Diesel or injection
specialist with test
equipment. This is
an inexpensive
check to have
carried out, while
the injectors are out.
• Step 7: Refit the injector, tightening it to the specified
tightening torque. See Chapter 3, Facts and Figures.
• Step 8: Reconnect all parts in the reverse order. Run the
engine at a fast idle initially to clear air from the high pressure
side of the fuel system.
Job 18. Bleeding Diesel fuel
system.
PART A: BLEEDING AIR FROM THE SYSTEM
If the engine stalls because of lack of fuel or if fuel low
pressure lines have been disconnected or fuel filter has been
changed, bleed the system as follows:
• Step A1: Unscrew the unions fastening the delivery lines
to the four injectors (A).

Job 13. Rear shock absorbers and
coil springs - replacement.
Q Step 12: ...then complete the
operation by using a standard
puller with a strong packing piece
(arrowed) for the puller shaft to
'push' against.
G Step 13: Remove the circlip
(see illustration Job
12-9,
part b)
and drift or press out the bearing
outer track from the hub carrier.
• Step 14: Check the hub
carrier for serviceability and
replace if it is in any way
damaged.
D INSIDE INFORMATION! The
new bearing is a complete
sealed unit and requires no
extra lubrication. D
• Step 15: Press the bearing
into the carrier using pressure on
the outer track ONLY (a). Fit the
circlip to retain it.
• Step 17:
Reassemble the front
suspension and brakes

in
the reverse order of
removal. See relevant

Jobs
for detailed infor-
mation. Use a NEW
hub nut fitted as
shown.
FACT FILE: STAKING THE HUB NUT
• Step 18: Use a cold

chisel
with an edge
ground to an angle of
about 60 degrees to stake

the
collar of the nut. USE

A
NEW NUT EACH TIME
IT IS REPLACED.
Q Step 19: Make sure the staked-down section of the collar

fits
in the stub axle

slot
in the opposite
direction to the
direction of the

nut
rotation, as
shown.
• Step 1: Refer to the drawings Job 1-1Cand 1-1D.
• Step 2: Leave the weight on the suspension by means of
a jack under the trailing arm (see illustration Job
1-1C,
part
• Step 3: Undo the nuts (see illustration Job
1-1D,
part
6)

and washers retaining the shock absorber (Job
1-1D,
part 5).
• Step 4: Pull the shock absorber off the top and bottom
mounting studs and carefully lower the jack to release the
pressure on, and then withdraw the coil spring. See also
Job 11
O Step 5: Refit in reverse order making sure that the coil
spring is properly seated top and bottom and that the shock
absorber nuts are tightened to the correct torque. See
Chapter
3,
Facts and Figures.
Job 14. Rear suspension and
wheel bearings - replacement.
Carry out this Job in connection with illustration Job
1-1C
and
1-1D.
• Step 1: IMPORTANT NOTE:
The trailing arms come
complete with bearings and
spacers (arrowed) as an
assembly. If the bearings are
defective, or the arm is cracked
or distorted, or showing signs
of wear or corrosion on the
wheel side, the whole assembly must be changed.
Q Step 2: Support the rear of the car on axle stands so that
the suspension hangs free. Remove the road wheels.
• Step 3: Remove the exhaust system. See PART F: FUEL
AND EXHAUST, Job 14.
• Step 4: Remove the fuel tank. See PART F: FUEL AND
EXHAUST, Job 10
• Step 5: Disconnect the brake pipes from the four-way
union and plug the ends to prevent excessive fluid loss.
Q Step 6: Slacken the cable adjustment under the
handbrake lever and disconnect the rear cable ends from the
equaliser. See PART H: BRAKES, Job 18
/ • Step 7: • Using a trolley
jack under the rear end of
the trailing arm to be
removed, compress the spring enough to undo the
mounting nuts and remove the shock absorber.
• Slowly lower the jack and remove the spring. This
allows you to use the weight of the car to help you
compress the spring
-
a difficult task otherwise!
Q Step 16: Press the hub into
the bearing, pushing ONLY on the
inner track with a suitable piece of
strong tube (1).

IMPORTANT NOTES:
3. We have sometimes shown the wiring diagram for a
'highest' spec, model, in the knowledge that 'lower'
spec, models are usually similar with the deletion of
certain components.
1. There are several hundred FIAT wiring diagrams for
the whole TIPO range. This is a representative selection,
covering the majority of applications. However, in the
event that your car's details are not covered here,
consult your nearest FIAT dealer.
