10:9 Brake fluid reservoir
The reservoir is located in the front compartment to the
side of the fuel tank as shown in FIG 10:9. Should it be
necessary to detach the fluid outlet line from the reservoir
the outlet hole must be blanked off using a tapered
wooden peg of suitable length so that the cap may be
replaced to prevent the ingress of foreign matter into
the reservoir and the absorbtion of moisture, oil or petrol
vapours which would alter the properties of the hydraulic
fluid.
A special filter is fitted into the top of the reservoir
through which all fluid used for topping-up the reservoir
must pass to ensure utmost inner cleanliness of the
hydraulic system.
10:10 Bleeding the system
This is not a routine maintenance operation and is only
necessary if air has entered the hydraulic system because
parts have been dismantled or because the f l u i d level in
the reservoir has dropped so low that air has been drawn
into the main feed pipe to the master cylinders.
1 Fill the reservoir w i t h Fiat 'Blue Label' hydraulic fluid.
During the bleeding operation fluid will be used and
constant topping-up of the supply reservoir will be
needed. If this is not done it is possible for air to enter
the master cylinder main feed pipe which will nullify
the operation and necessitate a fresh start.
2 Attach a length of rubber or plastic tubing to the
bleeder screw on the rear wheel cylinder furthermost
from the master cylinder. Immerse the free end of the
tube in a small volume of hydraulic brake fluid in a
clean jar.
3 Open the bleed screw one turn and get a second
operator to press down slowly on the brake pedal. After
a full stroke let the pedal return without assistance,
pause a moment and repeat the d o w n stroke. At first
there will be air bubbles issuing from the bleed tube,
but when fluid alone is ejected, hold the pedal firmly
down on the floor panel and tighten the bleed screw.
Repeat this operation on the other rear brake and then
repeat the operation on the two front brakes.
4 On completion, top-up the fluid in the reservoir to the
correct level. Discard all dirty fluid. If fluid is perfectly
clean, let it stand for twenty four hours to become
clear of air bubbles before using it again.
10:11 Hand parking brake
Normally with the new 500 Sedan model automatic
brake adjusting device, adjustment of the rear brakes
will take up excessive handbrake travel.
If there is excessive travel on the handbrake of the
Sedan model at any time, or in the case of Station Wagon
model even after the rear brakes have been manually
adjusted, suspect worn brake shoe linings or stretched
handbrake cables. Examine the linings and fit replace-
ment shoes if necessary. Check the action of the hand
parking brake again and if there is still too much travel
before the brakes are applied it is permissible to take up as
follows:
1 It is essential to ensure that the rear shoes are correctly
adjusted as described in Section 10:2.
2 Apply the hand parking brake lever until the pawl
engages with the ratchet at the second notch.

3 Jack up the rear of t h e vehicle and place on firmly
based stands.
4 Locate the cable adjusting nuts as shown in FIG
10:10 and adjust these until it is just possible to turn
the road wheels by heavy hand pressure. It is important
that both wheels offer the same resistance to turning
to obtain correctly balanced braking.
5 Return the lever to the OFF position and check that
both wheels are quite free to rotate. If a brake tends to
bind, remove the wheel and brake drum and check
the brake shoe pull-off spring is correctly fitted and
that the lever return spring and operating lever are
functioning correctly. Also check for suspected
seizure of the wheel cylinder. When the fault has
been rectified refit the drum. Readjust and recheck.
Removing the hand parking brake cable:
1 Chock the front wheels and release the handbrake.
Raise t h e rear of the vehicle and place on firmly based
stands.
2 Disconnect the cables from the operating levers on
each rear brake unit. Release each cable from its body
mounted bracket.
3 Inside the car, remove the rear seat and the seat belt
fitting from the floor. As necessary, remove the centre
console and the carpet to give access to the cover plate
on the centre tunnel and remove it.
4 Remove the handbrake lever assembly, detach the
cable compensator and pull the cables through the
holes in the box panel.
5 Reassembly is the reverse procedure to removal.
Ensure t h a t the cable is well lubricated and finally
readjust as previously described.
10:12 The dual circuit braking system
This is used on later model cars. A tandem master
cylinder provides t w o entirely separate hydraulic circuits,
one for the front and one for the rear brakes. The
components of the master cylinder are shown in the
exploded view of FIG 1 0 : 1 1 . The principle of operation is
quite straightforward and easy to understand.

6 Electrolyte level sight on filler neck
To test the condition of the cells use a hydrometer to
check the specific gravity of the.electrolyte. The readings
obtained should be as follows:
For climates below 27°C or 80°F:
Cell fully charged Specific gravity 1.270 to 1.290
Cell half-discharged Specific gravity 1.1 90 to 1.21 0
Cell discharged Specific gravity 1.11 0 to 1.130
For climates above 27°C or 80°F:
Cell fully charged Specific gravity 1.210 to 1.230
Cell half-discharged Specific gravity 1.130 to 1.150
Cell discharged Specific gravity 1.050 to 1.070
112These figures are given assuming an electrolyte
temperature of 16°C or 60°F. If the temperature of the
electrolyte exceeds this, add .002 to the readings for each
3°C or 5°F rise in temperature. Subtract .002 if it drops
below 16°C or 60°F.
All six cells should read approximately the same. If one
differs radically from the rest it may be due to an internal
fault or to spillage or leakage of the electrolyte.
If the battery is in a low state of charge take the car for
a long daylight run or connect it to an external battery
charger set at an output of 4 amps until it gases freely.
When putting the battery on a charger, remove the vent
plugs and ensure that no naked lights are in the vicinity.
If the battery is to stand unused for long periods give a
freshening up charge every month. It will deteriorate
rapidly if it is left in a discharged state.
11 :3 The generator
An exploded view of the generator is shown in
FIG 11 : 3 .
Testing when generator is not charging:
1 Check that drive belt slip is not the cause of the
trouble. Tension should be such that the belt can be
deflected about
inch under a 22 Ib pressure as
shown in FIG 1 :49. To adjust the drive belt tension
remove the three nuts B, FIG 1 :49, on the generator
pulley and this will split the pulley into two parts
between which are placed spacer rings. The tension of
the belt is increased or decreased by either reducing
or increasing the number of spacers. Place the spacer
rings removed from between the pulley halves on the
pulley outer face so that the rings may be reinserted
when fitting a new belt. Tighten the three nuts to a
torque wrench setting of 14.5 Ib ft. Care must be taken
not to over-tighten the belt or excessive loading will
be placed on the generator bearings causing excessive
bearing wear and noisy operation.
2 Check the generator connections. Generator terminal
51 must be connected to the generator regulator
terminal 51 and the generator terminal 67 to the
regulator terminal 67. Switch off all lights and
accessories and disconnect the cables from the
generator terminals 67 and 5 1 . Connect the two
terminals with a short length of wire. Run the engine at
normal idling speed and clip the negative lead of a
0-20 volt moving coil meter to one generator terminal
and the other lead to a good earth on the generator
body. Gradually increase the
engine speed up to about
1000 rev/min. The voltmeter reading should rise
steadily and without signs of fluctuation, but do not let
it reach 20 volts and do not race the engine in an
attempt to increase the reading.
3 If there is no reading check the brush gear. If the
reading is about half to one volt the field winding may
be faulty. If approximately four to five volts the arma-
ture may be faulty.
4 If the generator is in good order leave the temporary
link in position between the terminals and restore the
original connections correctly. Remove the terminal
51 from the regulator and connect the voltmeter
between this lead and a good earth on the car. Run
the engine as before. The reading should be the same
as that measured directly on the generator. No reading

Testing field coils:
When tested w i t h an ohmmeter the reading should be
8+.1—.3 ohms. Failing an ohmmeter use a 12-volt
supply and connect it in series w i t h an ammeter across
the field terminal and the yoke or body. The meter should
read approximately 2 amps. If there is no reading the
field coil winding has a break in it. If the reading is much
more than 2 amps or the ohmmeter records at much less
than 8 ohms it shows that field coil insulation has broken
down. Renewal of the field coils is a specialist operation
best left to a service station.
The armature:
Apart from reconditioning the commutator, there is
little which can be done to the armature itself. Never try
to straighten a bent shaft and do not machine the arma-
ture core. Armature windings are tested w i t h equipment
normally not available to the car owner. The only check
for a suspected faulty armature which the owner can do
is to substitute an armature which is known to be
satisfactory.
Generator bearings:
1 Commutator end head bearings. Remove the ball-
bearing outer race stop bracket mounting screw and
nut, ease o u t t h e stop brackets and the ballbearings.
2 Fan end head bearing. Remove the ballbearing retainer
mounting screw nuts and ease o u t t h e retainers and
the seals. Using a suitably sized drift remove the ball-
bearing.
114Reassembly is the reverse procedure to dismantling
in both cases.
Reassembly and refitting the generator:
This is the reverse procedure to dismantling. The
following points should however be noted.
1 The commutator end head ballbearing outer race stop
bracket mounting screw nut must be tightened to a
torque wrench setting of .80 Ib ft.
2 The pulley and fan-to-generator armature shaft self-
locking nuts must be tightened to a torque wrench
setting of 14.5 Ib ft.
3 To assemble the commutator end bracket to the yoke,
partially withdraw the brushes and trap them in this
position by letting the springs bear on the sides of the
brushes. Fit the bracket to the armature shaft and when
it is about 1/2 inch from the yoke face, lift the springs
using a thin screwdriver or a piece of hooked wire and
this will let the brushes drop onto the commutator.
Check that the springs now bear correctly on the tops
of the brushes and push the bracket fully home.
4 Pack all ballbearings with Fiat Jota 3 grease or an
equivalent grade grease.
11:4 The starter motor
Operation:
When operating the starter hand lever through a
flexible coupling a lever is operated (see FIG 11:5)
which controls the pinion engagement with the flywheel.
As the lever completes its movement it closes the starter

meter w i t h a fuller scale deflection of 40 amp must be
substituted. Adjust the rheostat to give maximum
resistance and operate the regulator for approximately
30 minutes with regulator controlled current and 13 volt
supply. The resistor R of the rheostat should be adjusted
until the current is steady whilst the voltage drops. This
will indicate that the unit has reached normal operating
temperature. Stop the generator, restart it and speed up
gradually to 4500 rev/min. Check that the regulated
current value corresponds to the specified value of
1 6± .5 amps. By continually reducing the resistance the
current should remain constant. The voltage however
should decrease to as l o w as 12 volts.
118
Cut-out relay adjustment:
Ascertain the type of regulator fitted and then wire to
the test unit as shown in FIG 11:10 or FIG 11 :12.
Before the unit is assembled to the test bed the instru-
ments should be set as follows:
P - at minimum so that voltmeter reads zero.
T — open.
R - all inserted giving maximum resistance.
T - open.
1 Contact closing voltage:
This test should be carried out at an ambient tempera-
ture of 25°±10°C. Close the switch T and stabilize the
regulator thermally by feeding current into it for approxi-
mately 15 to 18 minutes at 16.5 volts which is obtained
by adjusting P for initial regulator operating temperatures
of between 15°-20°C or at 15 volts for initial operating
temperatures of 20°-35°C. Once the stabilizing of the
regulator has been completed bring the voltage to 12 6±
.2 volts by adjusting P. Adjust the load on the setting
spring by bending the relevant arm until the pilot light S
is extinguished. Reset P to m inimum and again increase
the voltage by P and check that the pilot lamp is extin-
guished at the specified voltage.
2 Reverse current:
This test must be carried out at a temperature of
25°± 10°C and it is recommended that it is carried out as
soon as possible after the closing voltage test so as to
maintain minimum regulator thermal stability. With the
switch T closed bring the voltage to 14.5 volts by
operating P. The contacts of the cut-out should be closed
and the pilot lamp S off. Close T and increase the reverse
current by means of the rheostat R and check that the
pilot lamp S glows as the contacts part. The opening may
also be unsteady which will be indicated by a slight
buzz from the unit. Check the value of the ammeter of the
reverse current causing the opening of the contacts and
this should not exceed 16 amps. If the reading is unstable
or S lights up at the recommended limit reset the reverse
current to the minimum value and repeat the test once
more. Finally open the switches T and T and again
adjust rheostat R and P to the minimum settings.
Voltage regulator adjustment:
This test should be carried out at a temperature of
5 0 ° ±3 ° C . Connect the unit as shown in FIG 11 :11 and
load the voltage regulator adjusting springs by bending
the relevant arm. With the unit at the required test
temperature close 1 start the generator and stabilize
the regulator thermally by feeding a current for 30
minutes at 15 volts, which is obtained by adjusting the
generator speed. The generator should then be stopped,
I opened and the generator restarted and gradually
speeded up to 4500 rev/min. The voltage regulator
spring load adjustment should be set by suitably bending
the relevant adjusting arm and by rheostat R so as to have
a voltage of 14.2±.3 volts and a half load current of
8 ± 2 amps. Finally check the steadiness and accuracy
of the voltage regulator setting by stopping the generator
and restarting after approximately 2 minutes and gradually
speeding up to 4500 rev/min.

120signal lamp pairs. The flasher unit connections are in
FIG 11:14 and the unit is of the hot wire type.
Faulty operation of flashers:
In cases of trouble check the bulb for broken filaments.
Refer to the wiring diagrams in Technical Data and check
all flasher circuit cables and connections. Check the
appropriate fuse. Switch on the ignition and check w i t h
a voltmeter between flasher unit positive terminal and
earth to see if battery voltage is present. Connect together
flasher unit positive terminal and L and operate the
direction indicator switch. If the flasher lamps now light,
the flasher unit is defective and must be renewed. It is not
possible to dismantle and repair a faulty flasher unit.
Before removing make a note of the connections so that
they will be replaced correctly when the new unit is being
installed.
Before making the connections it is advisable to check
the circuits to ensure that the new flasher unit is not
damaged by wrong connection. Test by joining the
cables normally connected to the unit and operate the
switch. If the connections are wrong the appropriate
fuse will blow but no damage will be done to the flasher
unit.
Never insert terminal L directly to earth without having
first connected in series the bulbs specified, otherwise
the flasher unit will be damaged. For the same reason
terminal L must never be shorted to ground nor must there
by any short circuits in any of the leads from the L
terminal to the bulbs. The flasher unit must never receive
blows of any kind since it is a very delicate component
and easily damaged.
11:8 Windscreen wipers
Description:
The windscreen wiper assembly comprises a motor
unit that drives t w o wiper blades through a reduction
gearing and mechanical linkage. The reduction gear
includes a worm screw on the motor armature shaft and a
helical pinion. The motor, left blade pivot and linkages
are mounted on a sheet metal bracket, whilst the right
blade pivot is connected to the main drive link. When
assembled to the vehicle the right blade pivot is fixed
directly onto the body. The unit is provided w i t h an
automatic parking device which ensures that the blades
return to their correct park position. The w
indscreen wiper
is- controlled by a lever switch with three separate
positions on earlier models or a simple on-off switch on
later models.
Maintenance:
Maintenance is confined to the changing of the wiper
blades when they have deteriorated and occasional
lubricating of the mechanical linkage.
Wiper unit faulty operation :
1 It is important that the wiper unit assembly is correctly
fitted to the body otherwise distortion of the wiper
mounting bracket can occur which will cause
abnormal stresses on the pivot and linkages resulting
in irregular and difficult blade sweep.
2 If the blades keep on sweeping at a reduced speed
although the switch lever has been pressed to the

parking position the trouble will be found in the sliding
sector which fails to open the switch D (see FIG
11 :16) . Check by removing the four motor cover
mounting screws and uncover the sliding sector. If
possible suitably bend the sector to bring it against
into contact with the rod tip of switch D.
3 If the automatic parking of the blades does not occur
when the switch lever is fully depressed to the parking
position but the motor stops when the switch is
operated the cause of the trouble is that the switch D
is not closing and consequently no current is flowing
between the terminals C and INT. This will probably
be due to dirt lodged between the movable contact
and the fixed contacts of switch D. Thoroughly wash
the components with petrol and if necessary reface
the contacts using a very fine file.
4 Should the motor unit be noisy in operation although
still operating reliably the noise is probably due to the
reduction gear operation, whereby the pinion and
worm are excessively worn or a tooth chipped. The
motor unit must be renewed as motor unit parts are
not available in service.
5 If the switch lever is pushed upwards to the 'on'
position or depressed downwards to the Parking
position and the wiper is still inoperative thoroughly
check all terminal connections for tightness and
cables for damage which if all appear to be correct the
failure of the wiper to operate indicates an internal
fault of the motor unit which
should be repaired or
renewed as necessary.
Removal and refitting the motor:
Remove the wiper arms and the electrical connections
to the motor. Dismantling is a straightforward operation
providing that as all items are removed so they are
inspected and a note made of their locations. However,
reassembly requires more care and the following
procedure should be adopted.
1 Mount the wiper unit onto the body by fully tightening
the nuts fixing the pivots onto which the arms are
fitted. Ensure t h a t the rubber sealing bushes between
the pivots and body are correctly assembled to prevent
water ingress. Slightly lubricate with glycerine.
2 Secure the mounting bracket lower edge to the body
by means of the special square bracket. It is important
not to distort the mounting bracket and ease of
assembly is ensured by elongated holes in the square
bracket. By suitable adjustment the linkages will not
be subjected to distortion or abnormal stresses during
operation.
3 Fit the motor unit to the mounting bracket tightening
the screws and reassemble the main link to the pivot
lever. Ensure t h a t the l o c k i n g of the fastener on the
pivot lever is secure so that it does not become loose
during operation.
4 Remake all the electrical connections and run the
motor for a short time whilst checking all the switch
positions including the automatic parking. It is at this
position that the wiper blades and arms are assembled
to the wiper mechanism.
5 Onto the pivots, install the shims, snap ring, wiper arm,
plain washer and lockwasher. Fully tighten the nuts
with the wiper arms in the parked position.

downwards without striking against the cowl or front
compartment lid. Also ensure that the blade pressure
on the glass is 10.6 to 12.3 oz.
1 1 : 9 The lighting system
Description:
The lighting system comprises t w o headlights with
double filament bulbs of 45 watts for main beam and
40 watts for dip. Headlight control is operated through
the outer light switch below the steering wheel after the
toggle switch at the centre of the instrument panel has
been operated.
A double filament bulb for the front parking and
direction indicator lights is located below the headlights:
alternatively, the parking light may be incorporated in the
headlamp unit. The bulb is of 5 watt rating for the parking
lights and 20 watts for the direction indicator lights.
Two side direction indicator lamps are fitted with 2.5
w a t t b u l b s . The rear number plate is illuminated by a 5
watt bulb operated from the main lighting circuit.
Two three purpose rear light units are fitted and are
provided with a one single filament 20 watt bulb for the
direction indicator and one double filament bulb of 5 watt
rating for the parking circuit and 20 watt for stoplights.
Headlamp removal:
The headlamp on earlier cars may be removed from the
front panel by slightly depressing the lens and rotating the
unit counterclockwise through 15 deg. on later cars a
retaining spring is unhooked inside the front compart-
ment and the lamp can then be lifted out (FIG 11 :17).
121

Lamp brilliance varies w i t h the speed of t h e car:
Check the condition of the battery. Examine the battery
connections. Make sure they are tight and renew faulty
cables.
11:10 Panel and warning lights:
All the gauges are clustered in a single instrument
mounted on the dashboard above the steering column.
Incorporated in this cluster is the parking light pilot light,
generator charge indicator, fuel reserve supply indicator,
low oil pressure indicator, and the speedometer w i t h
mileage recorder.
The parking lamp indicator glows green when the
ignition lock switch key is in either position 1 or 2 once
the toggle switch on the instrument panel has been
operated.
The generator charge indicator shows red only when
the ignition is turned on. It should be extinguished when
the generator output is sufficient for battery charge
(12.6 ± 0.2 volts) with the engine running at a speed
of 1100 rev/min and the headlights switched off.
The fuel reserve supply indicator shows red only when
the ignition is turned on and the amount of fuel in the
petrol tank has dropped to approximately .8 to 1.1
Imp. gallons.
The low oil pressure indicator shows red only when the
ignition is turned on and should be extinguished when
the oil pressure reaches 7.1 to 21.3 Ib/sq in, and opens
the sending unit contacts. Once the engine is at normal
operating temperature but at a speed below 1000 rev/
min the indicator might light up even the pressure is under
control and with normal operation.
All the bulbs fitted to the above described units are of
the tubular 2.5W type and to renew a bulb extract the
bulb holder from the rear of t h e instrument cluster and
release the bulb which is attached by a normal bayonet
coupling.
Fuel reserve supply indicator sender u n i t:
The fuel reserve supply indicator should be checked for
correct indication by allowing the fuel tank to empty and
then inserting .8 to 1.1 Imp. gallons at which stage the
light should extinguish. Any failure to do so should be
checked as follows:
1 Ensure that the indicator bulb operates correctly.
2 Check for complete circuit between the sender unit and
the indicator bulb.
3 If the sender unit float bracket is distorted the bulb
will
indicate a reserve supply of fuel greater or smaller than
specified. The bracket should be adjusted to give
correct indication of fuel level.
4 The sender unit could have been inadvertantly
damaged in which case the unit must be renewed.
11 :11 The horn
The horn circuit comprises the horn, push button at the
centre of the steering wheel and normal earth return
electrical circuit through the car body. One terminal is
connected to the battery whilst the other to the push
button on the steering wheel which when the button is
depressed the circuit will be closed so causing the horn
to operate.

12:1 Bodywork finish
Large scale repairs to body panels are best left to
expert panel beaters. Even small dents can be tricky, as too
much hammering will stretch the metal and make things
worse instead of better. Filling minor dents and scratches
is probably the best method of restoring the surface. The
touching up of paintwork is well within the powers of
most car owners, particularly as self-spraying cans of
paint in the correct colours are now readily available. It
must be remembered, however, that paint changes colour
w i t h age and it is better to spray a whole wing rather than
try to touch up a small area.
Before spraying it is essential to remove all traces of
wax polish with white spirit. More drastic treatment is
required if silicone polishes have been applied. Use a
primer surfacer or paste stopper according to the amount
of filling required, and when it is dry, rub it down with
400 grade Wet or Dry paper until the surface is smooth
and flush with the surrounding area. Spend time on
getting the best finish as this will control the final effect.
Apply the retouching paint, keeping it wet in the centre
and light and dry round the edges. After a few hours of
drying, use a cutting compound to remove the dry spray
and finish with liquid polish.
F500127
12:2 Interior and chrome cleaning
The cloth upholstery of the seating and the rear
compartment lining must be regularly cleaned to ensure
long life and preserve its attractive appearance. Any dust
or dirt that is blown into the car will settle on the uphol-
stery and will tend to wear the cloth causing an unsightly
appearance. It is recommended that the dust is wiped off
using either a vacuum cleaner or a stiff brush. To remove
ordinary soiling of the upholstery cloth proceed as
follows:
1 Using luke warm water and a neutral soap and a piece
of clean cloth wipe over the upholstery in the direction
of the nap.
2 Repeat the operation using a clean damp cloth and
warm water but no soap.
3 Allow the upholstery cloth to dry, use a stiff brush
against the direction of the upholstery nap to restore
its original fluffy look.
To obtain best results, any stains must be removed as
soon as possible otherwise as time passes they will
become more difficult, if not impossible to remove.
Certain stains require specific solvents and the instruc-
tions must be strictly adhered to.

Cleaning imitation leather:
To keep the imitation leather clean wash in luke warm
water and a neutral soap applied with a soft cloth. Wipe
clean with a clean moistened cloth with no trace of soap
and finally rub with a clean dry cloth until the original
lustre is restored.

Chrome plated parts:
To ensure long life from the chrome plated parts these
should be periodically washed using a cloth dampened
with petrol and dried with a soft cloth. Rub with a cloth
moistened in clean oil especially around the edges of the
components and finally rub using a clean dry cloth until
all traces of oil have been apparently removed.
Glass panels:
The glass panels must be cleaned w i t h a chamois
leather or rag. Take care that no abrasive material is
allowed to be rubbed onto the glass otherwise it will be
scratched.
12:3 Door trim and accessories
The rear-hinged doors have welded upper and lower
hinge halves being joined by a fulcrum pin to the other
half of the hinge which is welded onto the body. Upon
reassembly of a hinge the fulcrum pins must be fitted with
the ball head uppermost. With front-hinged doors the
hinge is bolted to the body pillar.
Check strap (earlier models):
To limit the door opening, a rubber check strap is fixed
by four self-tapping screws of which two are located on
the door and t w o on the body. When a check strap is being
fitted the following points should be noted:
1 Always use sealing compound on the check strap
mounting holes to ensure a moisture t i g h t j o i n t .
2 Insert the screws in the plates and in the strap.
3 Always place a washer on each screw between the
body and the check strap, and also the door and check
strap. Tighten the screws fully.
Weather strip:
A one-piece moulded weather strip is fitted to the door
aperture and fixed by a special adhesive. Should the
weather strip become detached or a new one requiring to
be fitted proceed as follows:
1 Remove the old weather strip as necessary and thor-
oughly clean the door opening flange with petrol,
remove any rust spots and touch in the paint work.
2 Clean the new weather strips of their preservative or
the original from road dirt using petrol and thoroughly
wipe
clean.
3 Apply a coat of adhesive using a brush to the side to be
attached to the body. Allow to dry for the recom-
mended period of time and position the weather strip
on the door opening flange ensuring that it is not
distorted. The joint should be on the bottom side of
the rear end of the door opening. Apply a heavy
pressure on the weather strip starting from the centre
and working towards the ends.
Two rubber lining strips are located on the door flange
and these should be attached using the same procedure
detailed above.
Ensure that the bonding of the rubber weather strips
to both the door opening flange and the door panel is
thoroughly dry before the door is closed, otherwise this
could be the cause of subsequent water ingress.

1 2 : 9 Front compartment lid
The front compartment lid is hinged at the centre w i t h
the lower half of the hinge welded to the body upper
crossmember. The hinge upper half is secured to the
lower half by nuts and washers which are screwed onto
the lid studs. The compartment lid is kept closed by a
catch as shown in FIG 1 2 : 9 with an additional safety
hook to avoid accidental opening.
The catch release mechanism is controlled by a handle
which is located under the lefthand side of the instrument
panel and connected to the lock by means of a bowden
cable. The cable is arranged inside the front compartment
and the inner wire passes through a bracket and secured
to the catch. A return spring is fitted onto the catch, the
latter pivoting on a locked pin.
A specially shaped weather strip is arranged on the
front and side flange of the front compartment opening.
To refit and renew the weather strip ensure that all the old
bonding compound is removed using a stiff brush.
Spread fresh adhesive to the body shell and carefully
locate and press home the weather strip.
Six rubber bumpers are press fitted into the body shell
and at both ends of the front compartment lid to ensure
correct location and freedom of rattles.
12:10 Engine compartment lid
The opening and closing movement of the lid is con-
trolled by a locking handle. The lid opens downwards and
pivots on two lower hinges. The hinge pin is welded onto
the lid and its socket is welded to the body rear lower
crossmember. To remove the engine compartment lid
proceed as follows:
1 Remove the number plate lamp cable terminal.
2 Unhook the check strap by manipulating the retaining
cross piece.
3 Release the righthand pin self-locking nut and exert
a slight pressure on the righthand side of the lid so
pushing it towards the left.
Reassembly is the reverse procedure to dismantling.
