6For these models, note the following points:
a)The instrument cluster surround is
retained by two screws and two clips. It
will also be necessary to disconnect the
panel dimmer switch (see illustration).
b)When removing the cluster note that it will
also be necessary to release the retaining
clip and disconnect the speedometer
cable (see illustration).On refitting push
the cable back into position and check
that it is securely held in position with the
retaining clip.

61Refer to Chapter 7 part B.
Fuses
1The battery positive (live) lead is protected
by a fusible link. If this link melts, a major
short-circuit is indicated and expert advice
should be sought before repairing it.
2The main fuse/relay box is located under the
bonnet, near the bulkhead on the right-hand
side. It contains up to 24 fuses and nearly as
many relays (according to equipment). Fuse
applications are listed on the underside of the
fuse box lid (see illustration).
3There is an auxiliary fuse box inside the
vehicle, accessible after opening the glovebox
(see illustration). An in-line fuse for the radio
is located under the facia on the left-hand
side, near the heater.4The“blade” type fuses are colour-coded to
show their current rating. A blown fuse can be
recognised by the melted wire link in the
middle.
5To renew a blown fuse, first switch off the
circuit concerned. Pull the old fuse out of its
holder, using tweezers or long-nosed pliers.
Press in a new fuse of the same rating and try
the circuit again.
6If the new fuse blows immediately or within
a short time, do not carry on renewing fuses
but look for a short-circuit in the wiring to the
item(s) protected by the fuse. When more than
one item is protected by a single fuse,
switching on one item at a time until the fuse
blows will help to isolate the defect.
7Never fit a fuse of a higher rating (current
capacity) than specified, and do not bypass
fuses with silver foil or strands of wire. Serious
damage, including fire, could result.
8In some positions (such as for power
window and seat adjustment motors) circuit
breakers are fitted instead of fuses. These are
normally self-resetting once the cause of the
overload has been cleared.
Relays
9If a circuit or system served by a relay
develops a fault, always remember that the
problem could be in the relay. Testing is by
substitution of a known good unit. Beware of
substituting relays which look the same but
perform different functions(see illustration).10To renew a relay, simply unplug it from its
holder and plug in the new one. Access to the
relays in the main fuse box is as described for
the fuses. Access to the relays located behind
the facia is achieved by removing the facia
top.
11The sliding roof relay is located in the
overhead console.
Control units and modules
12The two major modules are the EEC IV
module (on fuel-injection models) and the ABS
control module. These are located below the
glovebox on the passenger side, and are
accessible after removing the under-dash trim.
13As with relays, testing by the home
mechanic is limited to substitution of known
good units. This is likely to be prohibitively
expensive on a trial and error basis so in case
of problems a Ford dealer or other competent
specialist should be consulted at an early
stage.
1Disconnect the battery negative lead and
unlock all the doors before starting work on
the central locking system. Make sure that the
keys are outside the vehicle before
reconnecting the battery on completion.
2Remove the door interior trim panel.

1Remove the overhead console.
2Remove the three bolts which secure the
motor (see illustration).Lower the motor,
disconnect the multi-plug and remove it.

3When refitting, make sure that the motor
drivegear meshes with the roof operating
mechanism. Refit the relay, reconnect the
multi-plug and secure the motor with the three
bolts.
4Check the operation of the motor, then refit
the overhead console.1All vehicles are fitted with an electrical
speedometer sender unit instead of a
mechanical cable. The sender unit is located on
the left-hand side of the transmission extension.
2Raise and securely support the front of the
vehicle. Place a drain pan underneath the
speedometer sender unit.
3Remove the securing bolt, pull the sender
unit out of the transmission and disconnect
the multi-plug (see illustration). Be prepared
for some spillage of gearbox oil or ATF
(automatic transmission fluid).
4If a new sender unit is being fitted, transfer
the driven gear and circlip from the old unit.
On automatic transmission models, also
transfer the O-ring.
5If the old sender unit had two connecting
wires and the new unit has three, the brown
wire must be cut at the multi-plug and an earth
tag fitted (see illustration).Consult a Ford
dealer if in doubt.
6Fit the new sender unit, using a new bolt
(M6 x 25 mm for manual gearbox, M6 x 35 mm
for automatic transmission). Besides the
sender unit, the bolt also secures the new
earth tag (when applicable), the radio earth
strap and the multi-plug retaining bracket.
7Connect the multi-plug and fit it to the
bracket.8If any spillage of gearbox oil or transmission
fluid occurred, top-up the level before the
vehicle is next run.

Introduction
A selection of good tools is a fundamental
requirement for anyone contemplating the
maintenance and repair of a motor vehicle. For
the owner who does not possess any, their
purchase will prove a considerable expense,
offsetting some of the savings made by doing-
it-yourself. However, provided that the tools
purchased meet the relevant national safety
standards and are of good quality, they will
last for many years and prove an extremely
worthwhile investment.
To help the average owner to decide which
tools are needed to carry out the various tasks
detailed in this manual, we have compiled
three lists of tools under the following
headings:
Maintenance and minor repair,
Repair and overhaul, and Special. Newcomers
to practical mechanics should start off with the
Maintenance and minor repairtool kit, and
confine themselves to the simpler jobs around
the vehicle. Then, as confidence and
experience grow, more difficult tasks can be
undertaken, with extra tools being purchased
as, and when, they are needed. In this way, a
Maintenance and minor repairtool kit can be
built up into a Repair and overhaultool kit over
a considerable period of time, without any
major cash outlays. The experienced do-it-
yourselfer will have a tool kit good enough for
most repair and overhaul procedures, and will
add tools from the Specialcategory when it is
felt that the expense is justified by the amount
of use to which these tools will be put.
Maintenance and minor repair tool
kit
The tools given in this list should be
considered as a minimum requirement if
routine maintenance, servicing and minor
repair operations are to be undertaken. We
recommend the purchase of combination
spanners (ring one end, open-ended the
other); although more expensive than open-
ended ones, they do give the advantages of
both types of spanner.
MCombination spanners:
Metric - 8, 9, 10, 11, 12, 13, 14, 15, 17 &
19 mmMAdjustable spanner - 35 mm jaw (approx)
MGearbox and final drive filler/level plug keys
MSpark plug spanner (with rubber insert)
MSpark plug gap adjustment tool
MSet of feeler blades
MBrake bleed nipple spanner
MScrewdrivers:
Flat blade - approx 100 mm long x 6 mm dia
Cross blade - approx 100 mm long x 6 mm
dia
MCombination pliers
MHacksaw (junior)
MTyre pump
MTyre pressure gauge
MOil can
MOil filter removal tool
MFine emery cloth
MWire brush (small)
MFunnel (medium size)
Repair and overhaul tool kit
These tools are virtually essential for anyone
undertaking any major repairs to a motor
vehicle, and are additional to those given in the
Maintenance and minor repairlist. Included in
this list is a comprehensive set of sockets.
Although these are expensive, they will be
found invaluable as they are so versatile -
particularly if various drives are included in the
set. We recommend the half-inch square-drive
type, as this can be used with most proprietary
torque wrenches. If you cannot afford a socket
set, even bought piecemeal, then inexpensive
tubular box spanners are a useful alternative.
The tools in this list will occasionally need to
be supplemented by tools from the Special
list:
MSockets (or box spanners) to cover range in
previous list (including Torx sockets)*
MReversible ratchet drive (for use with
sockets) (see illustration)
MExtension piece, 250 mm (for use with
sockets)
MUniversal joint (for use with sockets)
MTorque wrench (for use with sockets)
MSelf-locking grips
MBall pein hammerMSoft-faced mallet (plastic/aluminium or
rubber)
MScrewdrivers:
Flat blade - long & sturdy, short (chubby),
and narrow (electrician’s) types
Cross blade - Long & sturdy, and short
(chubby) types
MPliers:
Long-nosed
Side cutters (electrician’s)
Circlip (internal and external)
MCold chisel - 25 mm
MScriber
MScraper
MCentre-punch
MPin punch
MHacksaw
MBrake hose clamp
MBrake/clutch bleeding kit
MSelection of twist drills
MSteel rule/straight-edge
MAllen keys (inc. splined/Torx type) (see
illustration)
MSelection of files
MWire brush
MAxle stands
MJack (strong trolley or hydraulic type)
MLight with extension lead
* Some Imperial sized nuts and bolts may be
found on air conditioning and automatic
transmission components
Special tools
The tools in this list are those which are not
used regularly, are expensive to buy, or which
need to be used in accordance with their
manufacturer’s instructions. Unless relatively
difficult mechanical jobs are undertaken
frequently, it will not be economic to buy many
of these tools. Where this is the case, you
could consider clubbing together with friends
(or joining a motorists’ club) to make a joint
purchase, or borrowing the tools against a
deposit from a local garage or tool hire
specialist. It is worth noting that many of the
larger DIY superstores now carry a large range
of special tools for hire at modest rates.

The vehicle owner who does his or her own maintenance according
to the recommended service schedules should not have to use this
section of the manual very often. Modern component reliability is such
that, provided those items subject to wear or deterioration are
inspected or renewed at the specified intervals, sudden failure is
comparatively rare. Faults do not usually just happen as a result of
sudden failure, but develop over a period of time. Major mechanical
failures in particular are usually preceded by characteristic symptoms
over hundreds or even thousands of miles. Those components which
do occasionally fail without warning are often small and easily carried
in the vehicle.With any fault-finding, the first step is to decide where to begin
investigations. Sometimes this is obvious, but on other occasions, a
little detective work will be necessary. The owner who makes half a
dozen haphazard adjustments or replacements may be successful in
curing a fault (or its symptoms), but will be none the wiser if the fault
recurs, and ultimately may have spent more time and money than was
necessary. A calm and logical approach will be found to be more
satisfactory in the long run. Always take into account any warning
signs or abnormalities that may have been noticed in the period
preceding the fault - power loss, high or low gauge readings, unusual
smells, etc - and remember that failure of components such as fuses or

6Automatic transmission
Note:Due to the complexity of the automatic transmission, it is difficult
for the home mechanic to properly diagnose and service this unit. For
problems other than the following, the vehicle should be taken to a
dealer service department or automatic transmission specialist.
Fluid leakage
m m
Automatic transmission fluid is usually deep red in colour. Fluid
leaks should not be confused with engine oil, which can easily be
blown onto the transmission by air flow.
m mTo determine the source of a leak, first remove all built-up dirt and
grime from the transmission housing and surrounding areas, using a
degreasing agent or by steam-cleaning. Drive the vehicle at low speed,
so that air flow will not blow the leak far from its source. Raise and
support the vehicle, and determine where the leak is coming from. The
following are common areas of leakage:
a)Fluid pan ( transmission “sump”).
b)Dipstick tube (Chapter 1).
c)Transmission-to-fluid cooler fluid pipes/unions (Chapter 7B).
