the earth lead from the rear left-hand side of
the cylinder head.
3Unscrew the nuts securing the engine
mountings to the engine mounting brackets.
4Jack up the vehicle and support it securely
on axle stands (see “Jacking”). Ensure that
there is enough working room beneath the
vehicle.
5To improve access, disconnect the exhaust
downpipe from the manifold and remove the
exhaust system.
6Drain the engine oil into a suitable container.
7On models fitted with a catalytic converter,
release the securing clips and withdraw the
exhaust heat shield from under the vehicle for
access to the propeller shaft.
8Remove the propeller shaft.
9Where applicable, bend back the locktabs,
then unscrew the two bolts in each case
securing the two anti-roll bar mounting clamps
to the vehicle underbody. Lower the anti-roll
bar as far as possible.
10Proceed as described in paragraphs 30
and 31 of Section 5.
11Support the gearbox with a trolley jack,
using a block of wood between the jack and
the gearbox to spread the load.
12Unscrew the four nuts securing the
gearbox crossmember to the vehicle
underbody. Unscrew the central bolt securing
the crossmember to the gearbox, and remove
the crossmember. Note the position of the
earth strap, where applicable. Recover the
mounting cup, and the exhaust mounting
bracket and heat shield (as applicable).
13Lower the gearbox slightly on the jack,
then remove the circlip, and disconnect the
speedometer drive cable from the gearbox.
14Disconnect the wiring from the reversing
lamp switch, and on models with fuel-injection,
disconnect the wiring from the vehicle speed
sensor mounted in the side of the gearbox.
15Slacken and remove the two bolts and
washers (one either side) securing the gear
linkage support bracket to the gearbox.
16Using a pin punch, drive out the roll pin
securing the gearchange rod to the gear linkage.
17Attach a hoist to the engine lifting brackets
located at the front and rear of the cylinder head,
and slowly take the weight of the engine. Arrange
the lifting tackle so that the engine/gearbox
assembly will assume a steep angle of
approximately 40°to 45°as it is being removed.
18To improve clearance in the engine
compartment when lifting the engine, unboltthe engine mounting brackets from the
cylinder block, and remove them.
19Ensure that the steering wheel is positioned
in the straight-ahead position then, using a dab
of paint or a marker pen, make alignment marks
between the intermediate shaft lower clamp
and steering gear pinion. Slacken and remove
the lower clamp bolt then disconnect the
intermediate shaft from the steering gear.
20Detach the brake lines from the front
suspension crossmember.
21Support the crossmember with a jack (do not
remove the jack from under the gearbox), then
loosen the bolts securing the crossmember to the
underbody. Remove the crossmember securing
bolts, and carefully lower the crossmember to
allow sufficient room for the engine sump to clear
the steering rack and crossmember as the
engine/gearbox assembly is removed.
22Make a final check to ensure that all
relevant wires, pipes and hoses have been
disconnected to facilitate removal of the
engine/gearbox assembly.
23Raise the engine/gearbox, at the same
time lowering the trolley jack which is
supporting the gearbox.
24Place a suitable rod across the vehicle
underbody to support the gear linkage support
bracket whilst the gearbox is removed.
25Tilt the engine/gearbox assembly using
the hoist and the trolley jack, until the
assembly can be lifted from the vehicle. Take
care not to damage surrounding components.
26If the vehicle is to be moved, with the
engine/gearbox assembly removed, temporarily
refit the suspension crossmember and the anti-
roll bar to the underbody, and reconnect the
steering column to the intermediate shaft.
27To separate the engine from the gearbox,
proceed as follows.
28Remove the starter motor.
29Support the engine and gearbox
horizontally on blocks of wood.
30Unscrew the engine-to-gearbox bolts,
noting the locations of the bolts, and the
positions of the earth strap and any wiring clips
attached to the bolts. Recover any shims fitted
between the sump and the gearbox when
removing the lower engine-to-gearbox bolts.
31Unscrew the bolt from the engine adapter
plate.
32Pull the engine and gearbox apart, taking
care not to strain the gearbox input shaft. It
may be necessary to rock the units slightly to
separate them.
Note: Refer to Part A, Section 4 of this
Chapter and to the warning that appears at the
start of Section 5 before proceeding. A
suitable hoist and lifting tackle will be required
for this operation. Any suspected faults in the
automatic transmission should be referred to a
Ford dealer or automatic transmissionspecialist before removal of unit, as the
specialist fault diagnosis equipment is
designed to operate with the transmission in
the vehicle.
1Proceed as described in paragraphs 1 to 21
of Section 5.
2Unscrew the securing bolt, and disconnect
the earth lead from the rear left-hand side of
the cylinder head.
3Unscrew the nuts securing the engine
mountings to the engine mounting brackets.
4Jack up the vehicle and support it securely
on axle stands (see “Jacking”). Ensure that
there is enough working room beneath the
vehicle.

The exhaust system fitted in production is
made of aluminised steel, with stainless steel
used in the endplates and baffles of the rear
silencer. Individual sections of the system are
easily renewed in service.
Emission control for the UK market is
achieved largely by the inherent efficiency of
the fuel, ignition and engine management
systems. A welcome spin-off from such
efficiency is remarkably good fuel economy for
a vehicle of such size and weight.
Precautions
Fuel
Many of the procedures in this Chapter
require the removal of fuel lines and
connections which may result in some fuel
spillage. Residual pressure in fuel-injection
systems will remain in the fuel lines long after
the vehicle was last used, therefore extra care
must be taken when disconnecting a fuel line
hose. Loosen any fuel hose slowly to avoid a
sudden release of pressure which may cause
fuel spray. As an added precaution place a rag
over each union as it is disconnected to catch
any fuel which is forcibly expelled. Before
carrying out any operation on the fuel system
refer to the precautions given in “Safety first!”
at the beginning of this Manual and follow
them implicitly. Petrol is a highly dangerous
and volatile liquid and the precautions
necessary when handling it cannot be
overstressed
Tamperproof adjustment screws
Certain adjustment points in the fuel system
(and elsewhere) are protected by tamperproof
caps, plugs or seals. The purpose of such
tamperproofing is to discourage, and to deter,
adjustment by unqualified operators.
In some EU countries (though not yet in the
UK) it is an offence to drive a vehicle with
missing or broken tamperproof seals. Before
disturbing a tamperproof seal, satisfy yourself
that you will not be breaking local or national
anti-pollution regulations by doing so. Fit a
new seal when adjustment is complete when
this is required by law.
Do not break tamperproof seals on a vehicle
which is still under warranty.
Catalytic converter
The catalytic converter is a reliable and
simple device which needs no maintenance in
itself, but there are some facts of which an
owner should be aware if the converter is to
function properly for the full service life.
a)DO NOT use leaded petrol in a car
equipped with a catalytic converter the
lead will coat the precious metals,
reducing their converting efficiency and
will eventually destroy the converter.
b)Always keep the ignition and fuel systems
well-maintained in accordance with the
manufacturer’s schedule - particularly,
ensure that the air cleaner filter element,
the fuel filter and the spark plugs are
renewed at the correct interval - if the inletair/fuel mixture is allowed to become too
rich due to neglect, the unburned surplus
will enter and burn in the catalytic
converter, overheating the element and
eventually destroying the converter.
c)If the engine develops a misfire, do not
drive the car at all (or at least as little as
possible) until the fault is cured - the
misfire will allow unburned fuel to enter
the converter, which will result in
overheating, as noted above.
d)DO NOT push- or tow-start the car - this
will soak the catalytic converter in
unburned fuel, causing it to overheat when
the engine does start - see b) above.
e)DO NOT switch off the ignition at high
engine speeds - if the ignition is switched
off at anything above idle speed,
unburnedfuel will enter the (very hot)
catalytic converter, with the possible risk
of igniting on the element and damaging
the converter.
f)DO NOT use fuel or engine oil additives -
these may contain substances harmful to
the catalytic converter.
g)DO NOT continue to use the car if the
engine burns oil to the extent of leaving a
visible trail of blue smoke - the unburned
carbon deposits will clog the converter
passages and reduce the efficiency; in
severe cases the element will overheat.
h)Remember that the catalytic converter
operates at very high temperatures -
hence the heat shields on the car’s
underbody and the casing will become hot
enough to ignite combustible materials
which brush against it - DO NOT,
therefore, park the car in dry undergrowth,
over long grass or piles of dead leaves.
i)Remember that the catalytic converter is
FRAGILE, do not strike it with tools during
servicing work, take great care when
working on the exhaust system, ensure
that the converter is well clear of any jacks
or other lifting gear used to raise the car
and do not drive the car over rough
ground, road humps, etc, in such a way as
to “ground” the exhaust system.
j)In some cases, particularly when the car is
new and/or is used for stop/start driving, a
sulphurous smell (like that of rotten eggs)may be noticed from the exhaust. This is
common to many catalytic converter-
equipped cars and seems to be due to the
small amount of sulphur found in some
petrols reacting with hydrogen in the
exhaust to produce hydrogen sulphide
(H
2S) gas; while this gas is toxic, it is not
produced in sufficient amounts to be a
problem. Once the car has covered a few
thousand miles the problem should
disappear - in the meanwhile a change of
driving style or of the brand of petrol used
may effect a solution.
k)The catalytic converter, used on a well-
maintained and well-driven car, should
last for between 50 000 and 100 000 miles
- from this point on, careful checks should
be made at all specified service intervals
of the CO level to ensure that the
converter is still operating efficiently - if
the converter is no longer effective it must
be renewed.
See Chapter 1, Section 38.
1On carburettor models only, the air cleaner
can take in both hot and cold air. Hot air is
obtained from a shroud bolted to the exhaust
manifold.
2A flap valve in the air cleaner spout
determines the mix of hot and cold air. The
valve is operated by a vacuum diaphragm.
Vacuum is obtained from the inlet manifold
and is applied via a heat-sensing valve, which
cuts off the vacuum as the temperature of the
incoming air rises. Thus the air cleaner takes in
only hot air on starting from cold, changing
progressively to cold air as the engine warms
up (see illustrations).
3If the system fails, either the engine will take
a long time to warm up (flap stuck in “cold”
position), or it may run roughly and not
develop full power when warm (flap stuck in
“hot” position). Check it as follows.

16Start the engine and note the engine
speed (rpm). The engine speed should
increase above the normal idle speed, and
should be as given in the Specifications.
17If the engine speed is not as specified,
remove the tamperproof plug from the top of
the throttle kicker housing, and turn the
adjustment screw to give the specified speed.
18On completion of adjustment, fit a new
tamperproof cap.
19Disconnect the tubing from the inlet
manifold, and reconnect the throttle kicker
vacuum hose.
20Refit the plastic shield and the air cleaner.
On 2.4 & 2.9 litre V6 models especially,
residual pressure will remain in the fuel lines
long after the vehicle was last used therefore
the fuel system must be depressurised before
any hose is disconnected; the system is
depressurised via the vent valve on the fuel
rail, noting that it may be necessary to depress
the valve several times before the pressure is
fully released. As an added precaution place a
rag over the valve as it is depressed to catch
any fuel which is forcibly expelled. Before
carrying out any operation on the fuel system
refer to the precautions given in Safety first! at
the beginning of this Manual and follow them
implicitly. Petrol is a highly dangerous and
volatile liquid and the precautions necessary
when handling it cannot be overstressed.
Access to the relays is obtained by
removing the facia top cover (crash pad).
The relays are located on the passenger
side(see illustration). Also see Chapter 13,
Section 16.
See Chapter 1, Section 41.
SOHC and 2.8 litre V6 engines
1Idle speed is controlled by the EEC IV
module and no direct adjustment is possible.
2Idle mixture adjustment should not be
necessary on a routine basis. After component
renewal or a similar circumstance it may be
checked and adjusted as follows.
3The engine must be at operating temperature.
The valve clearances must be correct, the air
cleaner element must be clean and the ignition
system must be in good condition.
4Connect an exhaust gas analyser (CO
meter) and a tachometer (rev. counter) to the
engine as instructed by their makers.
5Run the engine at 3000 rpm for 15 seconds,
then allow it to idle. Repeat the procedure
every 60 seconds until adjustment is
complete.
6With the engine idling after the 3000 rpm
burst, record the CO level when the reading
has stabilised. The desired value is given in the
Specifications.
7If adjustment is necessary, remove the
tamperproof plug from the mixture adjusting
screw on the underside of the vane airflow
meter (see illustration).
8On V6 models, note that adjustment should
first be carried out on the front airflow meter.The rear meter should only be adjusted if the
range of adjustment on the front meter is
insufficient.
9Turn the mixture adjusting screw with a
hexagon key until the CO level is correct (see
illustration).
10Stop the engine and disconnect the test
gear.
11Fit a new tamperproof plug if required.
DOHC engine
Note: Before carrying out any adjustments
ensure that the ignition timing and spark plug
gaps are as specified. To carry out the
adjustments, an accurate tachometer and an
exhaust gas analyser (CO meter) will be
required.
12Idle speed is controlled by the EEC IV
module, and manual adjustment is not possible,
although the “base” idle speed can be adjusted
by a Ford dealer using special equipment.
13On models with a catalytic converter, the
mixture is controlled by the EEC IV module,
and no manual adjustment is possible.
14On models without a catalytic converter,
the idle mixture can be adjusted as follows.
15Run the engine until it is at normal
operating temperature.
16Stop the engine and connect a tachometer
and an exhaust gas analyser in accordance
with the manufacturer’s instructions.
17Start the engine and run it at 3000 rpm
for 15 seconds, ensuring that all electrical
loads (headlamps, heater blower, etc) are
switched off, then allow the engine to idle, and
check the CO content. Note that the reading
will initially rise, then fall and finally stabilise.
18If adjustment is necessary, remove the
cover from the mixture adjustment
potentiometer (located on the right-hand side
of the engine compartment, behind the MAP
sensor), and turn the screw to give the
specified CO content (see illustration).
19If adjustment does not produce a change
in reading, the potentiometer may be at the
extreme of the adjustment range. To centralise
the potentiometer, turn the adjustment screw
20 turns clockwise followed by 10 turns anti-
clockwise, then repeat the adjustment
procedure.
