and flexible hose connecting the turbocharger
to the intercooler (see illustration 4.12) . Use
adhesive tape to seal the turbocharger ports
against the entry of dirt.
3 Unbolt the horn nearest the intercooler.
4 Unbolt the radiator/intercooler assembly
from the bonnet closure panel and the body
crossmember.
5 Move the assembly as far as possible
towards the engine, and unbolt the intercooler
from the radiator; withdraw the intercooler.
Refitting
6 Refitting is the reverse of the removal
procedure, tightening all nuts and bolts to the
specified torque settings, and not forgetting
to unseal the turbocharger openings before
reconnecting the intercooler pipe and hose.
18 Turbocharger boost control valve - removal and refitting
2
Removal
1Disconnect the battery negative (earth) lead
(refer to Chapter 5A, Section 1).
2 Disconnect the control valve wiring at its
multi-plug (see illustration) .
3 Marking or labelling the valve hoses so that
each can be reconnected to its original union,
disconnect the hoses from the valve.
4 Remove the securing screws and withdraw
the valve.
Refitting
5 Refitting is the reverse of the removal
procedure; tighten the screws to the specified
torque setting.
19 Turbocharger boost pressure - checking and
adjustment
5
Accurate checking and adjustment of the
turbocharger boost pressure requires considerable skill and experience and the use
of Ford special tools and diagnostic test
equipment. This work should therefore be
entrusted to a Ford dealer or performance
engine specialist.

- removal,
examination and refitting
3
Removal
1 Disconnect the battery negative (earth) lead
(refer to Chapter 5A, Section 1).
2 Drain the cooling system as described in
Chapter 1.
3 Remove the air inlet components as
described in Section 4.
4 Disconnect the turbocharger coolant feed
and return hoses by slackening the clamps
and pulling the hoses off the turbocharger’s
metal pipes (see illustration) .
5 Remove the pipe and flexible hoses
connecting the turbocharger to the air cleaner
and intercooler. Use adhesive tape to seal the
turbocharger ports against the entry of dirt.
6 Disconnect the turbocharger oil feed and
return pipes by unscrewing the couplings.
7 Remove its three retaining screws and
withdraw the exhaust manifold heat shield.
8 Disconnect the exhaust system downpipe
from the turbocharger, then disconnect the
hose from the boost control valve to the
turbocharger wastegate control actuator.
9 Unscrew the exhaust manifold nuts, and
withdraw the manifold and turbocharger as an
assembly, protecting the radiator with
cardboard or similar.
10 To separate the turbocharger from the
manifold, flatten back the raised lockwasher tabs and unscrew the three retaining bolts.
Disconnect the turbocharger oil and coolant
pipes if required. This is as far as the unit can
be dismantled;
do notdisturb the wastegate
or its actuator and linkage.
Examination
11 With the turbocharger in the vehicle,
check that there are no air leaks around any
part of the air inlet components, and that the
boost control valve hoses are intact and
securely fastened.
12 With the turbocharger removed, check the
turbine wheels and blades (as far as possible)
for signs of wear or damage. Spin the turbine
and check that it rotates smoothly and easily,
with no sign of roughness, free play or
abnormal noise. If possible, check for axial
play (endfloat) of the shaft. Check that the
wastegate, its actuator and linkage show no
visible signs of wear, damage or stiffness due
to dirt and corrosion.
13 If any sign of wear or damage is found,
the turbocharger must be renewed.
Refitting
14 Refitting is the reverse of the removal
procedure, noting the following points: a) Refit the oil and coolant pipes, tightening
the unions to the specified torque
settings.
b) Always use new lockwashers when
refitting the turbocharger to the manifold;
again, tighten the bolts to their specified
torque setting.
c) Protect the radiator when refitting the
assembly, and always fit a new exhaust
manifold gasket.
d) Ensure that the oil feed and return pipes
are absolutely clean before reconnecting
them and tightening them to the specified
torque setting.
e) Owners are well advised to change the engine oil and filter whenever the
turbocharger is disturbed (see Chap-
ter 1).
f) When reassembly is complete and the
cooling system refilled (see Chapter 1),
disable the ignition system by
disconnecting the E-DIS ignition coil
wiring multi-plug, then turn the engine
over on the starter motor until the oil
pressure light goes out. This is essential
to ensure that the turbocharger oil supply
is established BEFORE the engine is
started; do not forget to reconnect
the coil before attempting to start the
engine

1 General information and
precautions
General information
The electrical system is of 12-volt negative
earth type. Power for the lights and all
electrical accessories is supplied by a
lead/acid battery, which is charged by the
engine-driven alternator.
This Chapter covers repair and service
procedures for the various electrical
components not associated with the engine.
Information on the battery, ignition system,
alternator, and starter motor can be found in
Chapter 5A and B.
All models from 1994 onwards are fitted
with a driver’s air bag, which is designed to
prevent serious chest and head injuries to the
driver during an accident. A similar bag for the
front seat passenger is also available. The
combined sensor and electronics for the air
bag is located next to the steering column
inside the vehicle, and contains a back-up
capacitor, crash sensor, decelerometer,
safety sensor, integrated circuit and
microprocessor. The air bag is inflated by a
gas generator, which forces the bag out of the module cover in the centre of the steering
wheel. A “clock spring” ensures that a good
electrical connection is maintained with the air
bag at all times - as the steering wheel is
turned in each direction, the spring winds and
unwinds.
An anti-theft alarm system is available on
later models, and is triggered if the vehicle is
broken into through the doors, bonnet, or
tailgate. The alarm will also be triggered if the
ignition or audio equipment is tampered with.
Additionally, from the 1994 model year
onwards, a Passive Anti-Theft System (PATS)
is fitted. This system, (which works
independently of the standard alarm) prevents
the engine from being started unless a
specific code, programmed into the ignition
key, is recognised by the PATS transceiver.
Precautions
Warning: Before carrying out
any work on the electrical
system, read through the
precautions given in “Safety
first!” at the beginning of this manual and
in Chapter 5A, Section 1.
Caution: Prior to working on any
component in the electrical system, the
battery negative lead should first be
disconnected, to prevent the possibility of electrical short-circuits and/or fires. If a
radio/cassette player with anti-theft
security code is fitted, refer to the
information given in the reference sections
of this manual before disconnecting the
battery.

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 engine management
systems), particularly where an electronic
control unit is used. Also refer to the
precautions given in Chapter 5A, Section 1.
General
1 A 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,

1 The horn is mounted forward on the left-
hand side of the engine compartment, near
the battery.
2 Disconnect the battery negative (earth) lead
(refer to Chapter 5A, Section 1).
3 Remove the wiring loom connection from
the horn(s).
4 Both single and dual horns are mounted to
a bracket which is secured to the bodywork
by a single bolt. Remove the bolt and
withdraw the horn(s) and bracket from the
vehicle. The horn(s) may be separated from
the bracket, as required, by removing the
retaining nut(s).
Refitting
5 Refitting is a reversal of removal.
15 Wiper arms -
removal and refitting
1
Removal
1 With the wiper(s) “parked” (ie in the normal
at-rest position), mark the positions of the
blade(s) on the screen, using a wax crayon or
strips of masking tape.
2 Lift up the plastic cap from the bottom of
the wiper arm, and loosen the nut one or two
turns.
3 Lift the wiper arm, and release it from the
taper on the spindle by moving it from side to
side.
4 Completely remove the nut and washer,
then withdraw the wiper arm from the

MOT test checksREF•11
REF
Seat belts and seats
Note: The following checks are applicable to
all seat belts, front and rear.
M Examine the webbing of all the belts
(including rear belts if fitted) for cuts, serious
fraying or deterioration. Fasten and unfasten
each belt to check the buckles. If applicable,
check the retracting mechanism. Check the
security of all seat belt mountings accessible
fr om inside the vehicle.
M The front seats themselves must be
secur ely attached and the backrests must
lock in the upright position.
Doors
M Both front doors must be able to be opened
and closed from outside and inside, and must
latch securely when closed.
V ehicle identification
M Number plates must be in good condition,
secur e and legible, with letters and numbers
corr ectly spaced – spacing at (A) should be
twice that at (B).
M The VIN plate and/or homologation plate
must be legible.
Electrical equipment
M Switch on the ignition and check the
operation of the horn.
M Check the windscreen washers and wipers,
examining the wiper blades; renew damaged
or perished blades. Also check the operation
of the stop-lights.
M Check the operation of the sidelights and
number plate lights. The lenses and reflectors
must be secure, clean and undamaged.
M Check the operation and alignment of the
headlights. The headlight reflectors must not
be tarnished and the lenses must be
undamaged.
M Switch on the ignition and check the
operation of the direction indicators (including
the instrument panel tell-tale) and the hazard
war ning lights. Operation of the sidelights and
stop-lights must not affect the indicators - if it
does, the cause is usually a bad earth at the
r ear light cluster.
M Check the operation of the rear foglight(s),
including the warning light on the instrument
panel or in the switch.
Footbrake
M Examine the master cylinder, brake pipes
and servo unit for leaks, loose mountings,
corr osion or other damage.
M The fluid reservoir must be secure and the
fluid level must be between the upper ( A) and
lower ( B) markings. M
Inspect both front brake flexible hoses for
cracks or deterioration of the rubber . Turn the
steering from lock to lock, and ensure that the
hoses do not contact the wheel, tyre, or any
part of the steering or suspension mechanism.
With the brake pedal firmly depressed, check
the hoses for bulges or leaks under pressure.
Steering and suspension
M Have your assistant turn the steering wheel
fr om side to side slightly, up to the point where
the steering gear just begins to transmit this
movement to the roadwheels. Check for
excessive free play between the steering
wheel and the steering gear, indicating wear or
insecurity of the steering column joints, the
column-to-steering gear coupling, or the
steering gear itself.
M Have your assistant turn the steering wheel
mor e vigorously in each direction, so that the
r oadwheels just begin to turn. As this is done,
examine all the steering joints, linkages,
fittings and attachments. Renew any
component that shows signs of wear or
damage. On vehicles with power steering,
check the security and condition of the
steering pump, drivebelt and hoses.
M Check that the vehicle is standing level,
and at approximately the correct ride height.
Shock absorbers
M Depr ess each corner of the vehicle in turn,
then release it. The vehicle should rise and
then settle in its normal position. If the vehicle
continues to rise and fall, the shock absorber
is defective. A shock absorber which has
seized will also cause the vehicle to fail.
2Checks carried out
WITH THE VEHICLE ON THE
GROUND
procarmanuals.com
http://vnx.su

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
