to repair the affected area. New body panels
are not as expensive as most people think,
and it is often quicker and more satisfactory to
fit a new panel than to attempt to repair large
areas of corrosion.
Remove all fittings from the affected area,
except those which will act as a guide to the
original shape of the damaged bodywork (eg
headlight shells etc). Then, using tin snips or a
hacksaw blade, remove all loose metal and
any other metal badly affected by corrosion.
Hammer the edges of the hole inwards, in
order to create a slight depression for the filler
paste.
Wire-brush the affected area to remove the
powdery rust from the
surface of the remaining metal. Paint the
affected area with rust-inhibiting paint, if the
back of the rusted area is accessible, treat this
also.
Before filling can take place, it will be
necessary to block the hole in some way. This
can be achieved by the use of aluminium or
plastic mesh, or aluminium tape.
Aluminium or plastic mesh, or glass-fibre
matting, is probably the best material to use
for a large hole. Cut a piece to the
approximate size and shape of the hole to be
filled, then position it in the hole so that its
edges are below the level of the surrounding
bodywork. It can be retained in position by
several blobs of filler paste around its
periphery.
Aluminium tape should be used for small or
very narrow holes. Pull a piece off the roll, trim
it to the approximate size and shape required,
then pull off the backing paper (if used) and
stick the tape over the hole; it can be
overlapped if the thickness of one piece is
insufficient. Burnish down the edges of the
tape with the handle of a screwdriver or
similar, to ensure that the tape is securely
attached to the metal underneath.
Bodywork repairs - filling and
respraying
Before using this Section, see the Sections
on dent, deep scratch, rust holes and gash
repairs.
Many types of bodyfiller are available, but
generally speaking, those proprietary kits
which contain a tin of filler paste and a tube of
resin hardener are best for this type of repair.
A wide, flexible plastic or nylon applicator will
be found invaluable for imparting a smooth
and well-contoured finish to the surface of the
filler.
Mix up a little filler on a clean piece of card
or board - measure the hardener carefully
(follow the maker’s instructions on the pack),
otherwise the filler will set too rapidly or too
slowly. Using the applicator, apply the filler
paste to the prepared area; draw the
applicator across the surface of the filler to
achieve the correct contour and to level the
surface. As soon as a contour that
approximates to the correct one is achieved,
stop working the paste - if you carry on too
long, the paste will become sticky and begin
to “pick-up” on the applicator. Continue to
add thin layers of filler paste at 20-minuteintervals, until the level of the filler is just proud
of the surrounding bodywork.
Once the filler has hardened, the excess can
be removed using a metal plane or file. From
then on, progressively-finer grades of abrasive
paper should be used, starting with a 40-
grade production paper, and finishing with a
400-grade wet-and-dry paper. Always wrap
the abrasive paper around a flat rubber, cork,
or wooden block - otherwise the surface of the
filler will not be completely flat. During the
smoothing of the filler surface, the wet-and-
dry paper should be periodically rinsed in
water. This will ensure that a very smooth
finish is imparted to the filler at the final stage.
At this stage, the “dent” should be
surrounded by a ring of bare metal, which in
turn should be encircled by the finely
“feathered” edge of the good paintwork. Rinse
the repair area with clean water, until all of the
dust produced by the rubbing-down operation
has gone.
Spray the whole area with a light coat of
primer - this will show up any imperfections in
the surface of the filler. Repair these
imperfections with fresh filler paste or
bodystopper, and once more smooth the
surface with abrasive paper. Repeat this
spray-and-repair procedure until you are
satisfied that the surface of the filler, and the
feathered edge of the paintwork, are perfect.
Clean the repair area with clean water, and
allow to dry fully.
The repair area is now ready for final
spraying. Paint spraying must be carried out in
a warm, dry, windless and dust-free
atmosphere. This condition can be created
artificially if you have access to a large indoor
working area, but if you are forced to work in
the open, you will have to pick your day very
carefully. If you are working indoors, dousing
the floor in the work area with water will help
to settle the dust which would otherwise be in
the atmosphere. If the repair area is confined
to one body panel, mask off the surrounding
panels; this will help to minimise the effects of
a slight mis-match in paint colours. Bodywork
fittings (eg chrome strips, door handles etc)
will also need to be masked off. Use genuine
masking tape, and several thicknesses of
newspaper, for the masking operations.
Before commencing to spray, agitate the
aerosol can thoroughly, then spray a test area
(an old tin, or similar) until the technique is
mastered. Cover the repair area with a thick
coat of primer; the thickness should be built
up using several thin layers of paint, rather
than one thick one. Using 400-grade wet-and-
dry paper, rub down the surface of the primer
until it is really smooth. While doing this, the
work area should be thoroughly doused with
water, and the wet-and-dry paper periodically
rinsed in water. Allow to dry before spraying
on more paint.
Spray on the top coat, again building up thethickness by using several thin layers of paint.
Start spraying at one edge of the repair area,
and then, using a side-to-side motion, work
until the whole repair area and about 2 inches
of the surrounding original paintwork is
covered. Remove all masking material 10 to 15
minutes after spraying on the final coat of
paint.
Allow the new paint at least two weeks to
harden, then, using a paintwork renovator, or a
very fine cutting paste, blend the edges of the
paint into the existing paintwork. Finally, apply
wax polish.
Plastic components
With the use of more and more plastic body
components by the vehicle manufacturers (eg
bumpers. spoilers, and in some cases major
body panels), rectification of more serious
damage to such items has become a matter of
either entrusting repair work to a specialist in
this field, or renewing complete components.
Repair of such damage by the DIY owner is
not really feasible, owing to the cost of the
equipment and materials required for effecting
such repairs. The basic technique involves
making a groove along the line of the crack in
the plastic, using a rotary burr in a power drill.
The damaged part is then welded back
together, using a hot-air gun to heat up and
fuse a plastic filler rod into the groove. Any
excess plastic is then removed, and the area
rubbed down to a smooth finish. It is important
that a filler rod of the correct plastic is used, as
body components can be made of a variety of
different types (eg polycarbonate, ABS,
polypropylene).
Damage of a less serious nature (abrasions,
minor cracks etc) can be repaired by the DIY
owner using a two-part epoxy filler repair
material. Once mixed in equal proportions, this
is used in similar fashion to the bodywork filler
used on metal panels. The filler is usually
cured in twenty to thirty minutes, ready for
sanding and painting.
If the owner is renewing a complete
component himself, or if he has repaired it with
epoxy filler, he will be left with the problem of
finding a suitable paint for finishing which is
compatible with the type of plastic used. At
one time, the use of a universal paint was not
possible, owing to the complex range of
plastics encountered in body component
applications. Standard paints, generally
speaking, will not bond to plastic or rubber
satisfactorily. However, it is now possible to
obtain a plastic body parts finishing kit which
consists of a pre-primer treatment, a primer
and coloured top coat. Full instructions are
normally supplied with a kit, but basically, the
method of use is to first apply the pre-primer
to the component concerned, and allow it to
dry for up to 30 minutes. Then the primer is
applied, and left to dry for about an hour
before finally applying the special-coloured
top coat. The result is a correctly-coloured
component, where the paint will flex with the
plastic or rubber, a property that standard
paint does not normally posses.

If bodystopper is used, it can be
mixed with cellulose thinners,
to form a thin paste which is
ideal for filling small holes.

Where serious damage has occurred or
large areas need renewal due to neglect, it
means certainly that completely new sections
or panels will need welding in and this is best
left to professionals. If the damage is due to
impact, it will also be necessary to completely
check the alignment of the bodyshell
structure. Due to the principle of construction,
the strength and shape of the whole car can
be affected by damage to one part. In such
instances the services of a Ford agent with
specialist checking jigs are essential. If a body
is left misaligned, it is first of all dangerous as
the car will not handle properly, and secondly
uneven stresses will be imposed on the
steering, engine and transmission, causing
abnormal wear or complete failure. Tyre wear
may also be excessive.
1Open and prop the bonnet.
2Mark around the bonnet hinge bolts, using
soft pencil or a washable marker pen, to
provide a guide when refitting (see
illustration).
3Disconnect the windscreen washer hose atthe non-return valve or washer pump. Be
prepared for fluid spillage.
4Disconnect the under-bonnet light (when
fitted).
5Free the insulation from around the left-
hand hinge bolts. With the help of an assistant,
support the bonnet and remove the hinge
bolts. Unhook the bonnet from the pump and
remove it.
6Refit by reversing the removal operations.
Make sure that the gap between the bonnet
and the wings is equal on both sides when the
bonnet is shut; adjust if necessary at the hinge
bolts.
7Adjust the bump stops and bonnet lock
striker if necessary to obtain satisfactory
opening and closing of the bonnet (see
illustration).
Later models
8The operation for later models is essentially
as described above, noting thatit will be
necessary to unclip the insulation panel from
the underside of the bonnet to gain access to
the windscreen washer hose and washer
nozzle heater wiring plugs (see illustration).
9Disconnect the wiring plugs and hose and
free them from the retaining clips on the right-
hand side of the bonnet before removal.
10On refitting ensure that the hose and
wiring are correctly routed and retained by all
the necessary clips before refitting the
insulation panel (see illustrations).1Open the door and disconnect the wiring
multi-plug from the door pillar (see
illustration).
2Unbolt the door check strap.
3Slacken, but do not remove, the hinge
cotter pin nuts (see illustration).
4Open the door to approximately 60°from
the vehicle body and lift it off the hinges. If the
door is reluctant to move, make sure that it is
opened to the correct angle and that the cotter
pin nuts are adequately slackened.
5Refit by reversing the removal operations.
Adjust the door striker plate if necessary as
described in Section 12.
6If a new door is to be fitted, new hinges will
have to be welded to it after trial fitting.
Consult a Ford dealer for details.

4Have an assistant support the tailgate.
Disconnect the struts from the tailgate.
5Jam the tailgate latch with a piece of wood
or cardboard so that the tailgate cannot shut.
Lower the tailgate.
6Working inside the vehicle, prise out the
hinge covers from the headlining. Remove the
hinge nuts and recover the washers (see
illustration).
7With the aid of an assistant, lift the tailgate
away from the vehicle.
8Commence refitting by offering the tailgate
to its aperture, aligning the hinges and
reconnecting the struts. Do not allow the
struts alone to support the tailgate until the
hinge nuts have been fitted.
9Fit the hinge nuts and washers. Do not fully
tighten the nuts yet.
10Secure any wiring looms and the washer
tube to the pieces of string used during
removal. (It is to be hoped that a new tailgate
will be supplied with wiring or string in place.)
Draw the wires and tube into position. Tape up
the connectors if necessary to prevent them
snagging.
11Reconnect the wires and the washer tube
and refit the grommets.
12Close and latch the tailgate and adjust its
position so that an even gap exists all round it,
then tighten the hinge nuts.
13Refit the hinge covers and the interior trim
panel.
Estate models
14On Estate models the tailgate can be
removed and refitted as described above,
noting the following points:
a)Prior to removing the interior trim panel. it
will be necessary to remove the upper rear
windscreen trim panel which is retained by
eight screws.
b)When removing the interior trim panel
note that it is retained by fourteen screws;
two are situated behind each of theaccess covers in the centre of the panel.
c)To gain access to the tailgate hinge
retaining nuts it will be necessary to
carefully peelthe headlining away from the
rear trim panel. Therefore if hinge removal
is not strictly necessary, it is
recommended that the hinges are left in
place on the vehicle and the tailgate is
unbolted from the hinges (see
illustration).
1On saloon models, open the boot lid and
using a suitable marker pen, mark the outline
of the hinges on the inside of the lid.
2Unclip the trim panel from the inside of the
lid to gain access to the boot lid lock and
warning switch wiring connectors (see
illustration). Release the wiring loom from the
retaining clips and tie a suitable length of
string to each of the wiring connectors.
Withdraw the wiring loom from the boot lid
until the connectors emerge then untie the
string and leave it in position in the lid; the
string can then be used to draw the wiring
loom back into position on refitting.
3Support the lid with the aid of an assistant
then slacken and remove the four hinge
retaining bolts (accessed from inside the lid)
and remove the boot lid from the car (see
illustration).
4Offer up the boot lid, aligning the hinges
with the marks made on removal, and tightenthe hinge bolts securely. Tie the piece of string
to the wiring loom and use the string to draw
the loom through the boot lid. If a new boot lid
is being installed it will be necessary to
centralise the boot lid on the hinges and feed
the wiring loom through the boot lid, ensuring
that it is correctly routed.
5Reconnect the wiring connectors to the lock
and warning switch.
6Refit the trim panel and check it is securely
held in position by the retaining clips.
7Close the boot lid and check that is
correctly aligned with all surrounding
bodywork with an equal clearance all around.
If necessary, adjustment can be made by
slackening the hinge bolts and repositioning
the boot lid. Once correctly positioned, tighten
the hinge bolts securely.
8Once the boot lid is correctly aligned ensure
that it closes without slamming and is securely
retained. If not, slacken the boot lid striker
retaining bolts and reposition the striker. Once
the boot lid operation is satisfactory tighten
the striker retaining bolts securely.

19Slacken and remove the two switch panel
retaining screws then carefully slide the panel
up over the handbrake lever until the switch
wiring connectors can be accessed (see
illustrations). Disconnect the wiring
connectors from all the switches, then release
the loom from any relevant retaining clips and
manoeuvre the switch panel off the handbrake
lever.
20Slacken and remove the seven centre
console retaining screws (two at the front, one
on each side and three at the rear) then lift up
the console and disconnect the wiring
connector from the rear cigarette lighter.
Remove the console assembly from the car
(see illustrations).
21Refitting is a reverse of the removal
procedure.
1Disconnect the battery negative lead.
2Remove the interior light by carefully prising
it out of the console and disconnecting it.
3Remove the sliding roof control handle or
switches (as applicable).
4Remove the two retaining screws from the
front of the console. Pull the front of the
console down and then slide the assembly
rearwards to release it from the two clips (see
illustrations). These clips may be quite tight.
Disconnect the clock.
5Refit by reversing the removal operations.1Move the seat rearwards as far as possible,
then remove the two front retaining bolts (see
illustration).
2Disconnect the assist spring from under the
driver’s seat. (Moving the seat forwards will
reduce the tension on this spring, but also
makes it harder to get at.)
3When applicable, disconnect the seat
heating and/or adjustment motor multi-plugs.
4Move the seat fully forwards and remove the
three rear retaining bolts. These bolts are
under plastic covers (see illustrations).
5Lift out the seat, complete with adjustment
mechanism and seat belt buckle.
6If a new seat is being fitted, transfer the
adjustment mechanism and other components
to it.
7Refit by reversing the removal operations.
Tighten the seat retaining bolts to the
specified torque.
1Remove the front seat as described in the
previous Section.
2Remove the side trim pieces from the seat.
Free the air tube by removing Its two securing
screws.
3Separate the backrest from the base of theseat by removing the four retaining bolts.
4Remove the backrest cover by unbending
its retaining tags and sliding it off.
5Expose the air cushion by lifting up the foam
padding. Cut the hog rings (wire loops) which
secure the corners of the cushion and remove
it with the air hoses.
6When refitting, use new hog rings. Position
the cut-out in the cushion level with the
second spring in the backrest.
7The remainder of refitting is a reversal of the
removal procedure.
1All models are fitted with inertia reel front
seat belts as standard. Rear seat belts are
available as an extra.
2Maintenance is limited to periodic
inspection of the belts for fraying or other
damage. Also check the operation of the
buckles and retractor mechanisms. In case of
damage or malfunction the belt must be
renewed.
3If it is wished to clean the belts, use only an
approved upholstery cleaner or a weak
solution of detergent, followed by rinsing with
water. Do not use solvents, strong detergents,
dyes or bleaches. Keep the belt extended until
it is dry.
4Belts which have been subjected to impact
loads must be renewed.
1Remove the cover from the belt top anchor.
With the adjustable type of anchor(see
illustration)the cover is removed by levering
out the adjuster button and removing two
screws.
2Remove the anchor bolt or nut and detach
the seat belt runner from it. Note the position
of any washers or spacers.
3Carefully pull out the door aperture
weatherstrips (front and rear) from the B-pillar
(see illustration). Unclip the pillar trim.
4Remove the screws which secure the
retractor cover trim, pull away more of the

The electrical system is a 12 volt, negative
earth type. Electricity is generated by an
alternator, belt-driven from the crankshaft pulley.
A lead-acid battery provides a reserve of power
for starting and when the demands of the system
temporarily exceed the alternator output.
The battery negative terminal is connected
to “earth” - vehicle metal - and most electrical
system components are wired so that they
only receive a positive feed, the current
returning via vehicle metal. This means that
the component mounting forms part of the
circuit. Loose or corroded mountings can
therefore cause apparent electrical faults.
Many semiconductor devices are used in
the electrical system, both in the “black
boxes” which control vehicle functions and in
other components. Semiconductors are very
sensitive to excessive (or wrong polarity)
voltage, and to extremes of heat. Observe the
appropriate precautions to avoid damage.
Although some repair procedures are given
in this Chapter, sometimes renewal of a well-
used item will prove more satisfactory. The
reader whose interests extend beyond
component renewal should obtain a copy of
the “Automobile Electrical Manual”, available
from the publishers of this book.
Before starting work on the electrical
system, read the precautions listed in “Safety
first!” at the beginning of the manual.
Note:Refer to the precautions given in “Safety
first!” and in Section 1 of this Chapter before
starting work. The following tests relate to testing
of the main electrical circuits, and should not be
used to test delicate electronic circuits (such as
anti-lock braking systems), particularly where an
electronic control unit (ECU) is involved.
General
1A typical electrical circuit consists of an
electrical component, any switches, relays,
motors, fuses, fusible links or circuit breakers
related to that component, and the wiring and
connectors which link the component to both
the battery and the chassis. To help to
pinpoint a problem in an electrical circuit,
wiring diagrams are included at the end of this
Chapter.
2Before attempting to diagnose an electrical
fault, first study the appropriate wiring
diagram, to obtain a more complete
understanding of the components included in
the particular circuit concerned. The possible
sources of a fault can be narrowed down by
noting whether other components related to
the circuit are operating properly. If several
components or circuits fail at one time, the
problem is likely to be related to a shared fuse
or earth connection.
3Electrical problems usually stem from
simple causes, such as loose or corroded
connections, a faulty earth connection, a
blown fuse, a melted fusible link, or a faulty
relay. Visually inspect the condition of all
fuses, wires and connections in a problem
circuit before testing the components. Use the
wiring diagrams to determine which terminal
connections will need to be checked in order
to pinpoint the trouble-spot.
4The basic tools required for electrical fault-
finding include: a circuit tester or voltmeter (a
12-volt bulb with a set of test leads can also
be used for certain tests), a self-powered test
light (sometimes known as a continuity tester),
an ohmmeter (to measure resistance), a
battery and set of test leads, and a jumper
wire, preferably with a circuit breaker or fuse
incorporated, which can be used to bypass
suspect wires or electrical components.
Before attempting to locate a problem with
test instruments, use the wiring diagram to
determine where to make the connections.
5To find the source of an intermittent wiring
fault (usually due to a poor or dirty connection,
or damaged wiring insulation), an integrity testcan be performed on the wiring, which
involves moving the wiring by hand, to see if
the fault occurs as the wiring is moved. It
should be possible to narrow down the source
of the fault to a particular section of wiring.
This method of testing can be used in
conjunction with any of the tests described in
the following sub-Sections.
6Apart from problems due to poor
connections, two basic types of fault can
occur in an electrical circuit - open-circuit or
short-circuit.
7Open-circuit faults are caused by a break
somewhere in the circuit, which prevents
current from flowing. An open-circuit fault will
prevent a component from working, but will
not cause the relevant circuit fuse to blow.
8Short-circuit faults are caused by a “short”
somewhere in the circuit, which allows the
current flowing in the circuit to “escape” along
an alternative route, usually to earth. Short-
circuit faults are normally caused by a
breakdown in wiring insulation, which allows a
feed wire to touch either another wire, or an
earthed component such as the bodyshell. A
short-circuit fault will normally cause the
relevant circuit fuse to blow. Note: A short-
circuit that occurs in the wiring between a
circuit’s battery supply and its fuse will not
cause the fuse in that particular circuit to blow.
This part of the circuit is unprotected - bear
this in mind when fault-finding on the vehicle’s
electrical system.
Finding an open-circuit
9To check for an open-circuit, connect one
lead of a circuit tester or voltmeter to either the
negative battery terminal or a known good earth.
10Connect the other lead to a connector in
the circuit being tested, preferably nearest to
the battery or fuse.
11Switch on the circuit, bearing in mind that
some circuits are live only when the ignition
switch is moved to a particular position.
12If voltage is present (indicated either by
the tester bulb lighting or a voltmeter reading,
as applicable), this means that the section of
