resonator to the air mass meter and plenum
chamber hoses, then swing the resonator up
clear of the thermostat housing (see Chapter
4). Unbolt the pulse-air filter housing from the
mounting bracket, then unfasten thebolts/nuts securing the mounting to the
subframe, unscrew the centre bolt and
withdraw the mounting; note the location of
the wiring connector bracket. The mounting’s
bracket can be unbolted from the
transmission if required (see illustration).
9On refitting, ensure that the mounting-to-
transmission bolts are securely tightened,
then refit the mounting and wiring connector
bracket. Tighten first the mounting-to-
subframe bolts/nuts, noting that these are to
be tightened in two stages to the final
specified torque wrench setting. Finally
tighten the mounting’s centre bolt, again to
the specified torque wrench setting.
Right-hand mounting
10Unscrew the nuts and withdraw the
bracket; note that these nuts are self-locking,
and must therefore be renewed wheneverthey are disturbed. Unbolt the mounting from
the body (see illustration).
11Where hydraulic-type mountings are
fitted - there are only five nuts securing the
bracket, and the mounting is clearly
identifiable from its shape - take care never to
tilt these more than 5° from the vertical (see
illustration).
12On refitting, renew the self-locking nuts,
and tighten all fasteners to the torque wrench
settings specified. When tightening the nuts,
tighten first the four bracket-to-engine nuts,
then release the hoist or jack to allow the
engine/transmission’s weight to rest on the
mounting. Do not allow the mounting to twist
as the last two of the nuts are tightened (see
illustration).
Left-hand mounting
13Unplugging the two electrical connectors,
disconnecting the vacuum hose (where fitted)
and disconnecting the crankcase breather
hose from the cylinder head cover, remove
the complete air cleaner assembly with the air
mass meter, the resonator and the plenum
chamber (see Chapter 4).
14Unscrew the three nuts to release the
mounting from the transmission, then unbolt
it from the body (see illustration). Note that

2B•2 Engine removal and general engine overhaul procedures

Page 69 of 279

How to use this Chapter
This Part of Chapter 2 is devoted to
engine/transmission removal and refitting, to
those repair procedures requiring the removal
of the engine/transmission from the vehicle,
and to the overhaul of engine components. It
includes only the Specifications relevant to
those procedures. Refer to Part A for
additional Specifications, if required.
General information
The information ranges from advice
concerning preparation for an overhaul and
the purchase of replacement parts, to detailed
step-by-step procedures covering removal
and installation of internal engine components
and the inspection of parts.
The following Sections have been written
based on the assumption that the engine has
been removed from the vehicle. For
information concerning in-vehicle engine
repair, as well as removal and installation of
the external components necessary for the
overhaul, see Part A of this Chapter and
Section 5 of this Part.
When overhauling this engine, it is essential
to establish first exactly what replacement
parts are available. At the time of writing,
components such as the piston rings are not
available separately from the
piston/connecting rod assemblies; pistons,
gudgeon pins and valve guides are not
available separately, and very few under- or
oversized components are available for
engine reconditioning. In most cases, it would
appear that the easiest and most
economically-sensible course of action is to
replace a worn or damaged engine with an
exchange unit.
It’s not always easy to determine when, or
if, an engine should be completely
overhauled, as a number of factors must be
considered.
High mileage is not necessarily an
indication that an overhaul is needed, while
low mileage doesn’t preclude the need for an
overhaul. Frequency of servicing is probably
the most important consideration. An engine
that’s had regular and frequent oil and filter
changes, as well as other required
maintenance, will most likely give many
thousands of miles of reliable service.
Conversely, a neglected engine may require
an overhaul very early in its life.
Excessive oil consumption is an indication
that piston rings, valve seals and/or valve
guides are in need of attention. Make surethat oil leaks aren’t responsible before
deciding that the rings and/or guides are
worn. Perform a cylinder compression check
(Part A of this Chapter, Section 3) to
determine the extent of the work required.
Loss of power, rough running, knocking or
metallic engine noises, excessive valve train
noise and high fuel consumption rates may
also point to the need for an overhaul,
especially if they’re all present at the same
time. If a full service doesn’t remedy the
situation, major mechanical work is the only
solution.
An engine overhaul involves restoring all
internal parts to the specification of a new
engine. Note:Always check first what
replacement parts are available before
planning any overhaul operation; refer to
Section 1 of this Part. Ford dealers, or a good
engine reconditioning specialist/automotive
parts supplier may be able to suggest
alternatives which will enable you to overcome
the lack of replacement parts.
During an overhaul, it is usual to renew the
piston rings, and to rebore and/or hone the
cylinder bores; where the rebore is done by an
automotive machine shop, new oversize
pistons and rings will also be installed - all
these operations, of course, assume the
availability of suitable replacement parts. The
main and big-end bearings are generally
renewed and, if necessary, the crankshaft
may be reground to restore the journals.
Generally, the valves are serviced as well,
since they’re usually in less-than-perfect
condition at this point. While the engine is
being overhauled, other components, such as
the starter and alternator, can be renewed as
well, or rebuilt, if the necessary parts can be
found. The end result should be an as-new
engine that will give many trouble-free miles.
Note:Critical cooling system components
such as the hoses, drivebelt, thermostat and
water pump MUST be replaced with new
parts when an engine is overhauled. The
radiator should be checked carefully, to
ensure that it isn’t clogged or leaking (see
Chapter 3). Also, as a general rule, the oil
pump should be renewed when an engine is
rebuilt.
Before beginning the engine overhaul, read
through the entire procedure to familiarise
yourself with the scope and requirements of
the job. Overhauling an engine isn’t difficult,
but it is time-consuming. Plan on the vehicle
being off the road for a minimum of two
weeks, especially if parts must be taken to an
automotive machine shop for repair or
reconditioning. Check on availability of parts,
and make sure that any necessary special
tools and equipment are obtained in advance.
Most work can be done with typical hand
tools, although a number of precision
measuring tools are required, for inspecting
parts to determine if they must be replaced.
Often, an automotive machine shop will
handle the inspection of parts, and will offer
advice concerning reconditioning andreplacement. Note:Always wait until the
engine has been completely dismantled, and
all components, especially the cylinder
block/crankcase, have been inspected, before
deciding what service and repair operations
must be performed by an automotive machine
shop. Since the block’s condition will be the
major factor to consider when determining
whether to overhaul the original engine or buy
a rebuilt one, never purchase parts or have
machine work done on other components
until the cylinder block/crankcase has been
thoroughly inspected.As a general rule, time
is the primary cost of an overhaul, so it
doesn’t pay to install worn or sub-standard
parts.
As a final note, to ensure maximum life and
minimum trouble from a rebuilt engine,
everything must be assembled with care, in a
spotlessly-clean environment.
If you’ve decided that an engine must be
removed for overhaul or major repair work,
several preliminary steps should be taken.
Locating a suitable place to work is
extremely important. Adequate work space,
along with storage space for the vehicle, will
be needed. If a workshop or garage isn’t
available, at the very least, a flat, level, clean
work surface made of concrete or asphalt is
required.
Cleaning the engine compartment and
engine/transmission before beginning the
removal procedure will help keep tools clean
and organized.
The engine can only be withdrawn by
removing it complete with the transmission;
the vehicle’s body must be raised and
supported securely, sufficiently high that the
engine/transmission can be unbolted as a
single unit and lowered to the ground; the
engine/transmission unit can then be
withdrawn from under the vehicle and
separated. An engine hoist or A-frame will
therefore be necessary. Make sure the
equipment is rated in excess of the combined
weight of the engine and transmission. Safety
is of primary importance, considering the
potential hazards involved in removing the
engine/transmission from the vehicle.
If this is the first time you have removed an
engine, a helper should ideally be available.
Advice and aid from someone more
experienced would also be helpful. There are
many instances when one person cannot
simultaneously perform all of the operations
required when removing the engine/
transmission from the vehicle.
Plan the operation ahead of time. Arrange for,
or obtain, all of the tools and equipment you’ll
need prior to beginning the job. Some of the
equipment necessary to perform
engine/transmission removal and installation

safely and with relative ease, and which may
have to be hired or borrowed, includes (in
addition to the engine hoist) a heavy-duty trolley
jack, a strong pair of axle stands, some wooden
blocks, and an engine dolly (a low, wheeled
platform capable of taking the weight of the
engine/transmission, so that it can be moved
easily when on the ground). A complete set of
spanners and sockets (as described in the front
of this manual) will obviously be needed,
together with plenty of rags and cleaning
solvent for mopping-up spilled oil, coolant and
fuel. If the hoist is to be hired, make sure that
you arrange for it in advance, and perform all of
the operations possible without it beforehand.
This will save you money and time.
Plan for the vehicle to be out of use for
quite a while. A machine shop will be required
to perform some of the work which the do-it-
yourselfer can’t accomplish without special
equipment. These establishments often have
a busy schedule, so it would be a good idea
to consult them before removing the engine,
to accurately estimate the amount of time
required to rebuild or repair components that
may need work.
Always be extremely careful when removing
and installing the engine/transmission.
Serious injury can result from careless
actions. By planning ahead and taking your
time, the job (although a major task) can be
accomplished successfully.
Warning: Petrol is extremely
flammable, so take extra
precautions when disconnecting
any part of the fuel system. Don’t
smoke, or allow naked flames or bare light
bulbs in or near the work area, and don’t
work in a garage where a natural gas
appliance (such as a clothes dryer or water
heater) is installed. If you spill petrol on
your skin, rinse it off immediately. Have a
fire extinguisher rated for petrol fires
handy, and know how to use it.Note: Read through the entire Section, as well
as reading the advice in the preceding Section,
before beginning this procedure. The engine
and transmission are removed as a unit,
lowered to the ground and removed from
underneath, then separated outside the vehicle.
Removal
1Park the vehicle on firm, level ground, apply
the handbrake firmly, and slacken the nuts
securing both front roadwheels.
2Relieve the fuel system pressure (see
Chapter 4).
3Disconnect the battery negative (earth) lead
- see Chapter 5, Section 1. For better access
the battery may be removed completely (see
Chapter 5).
4Place protective covers on the wings and
engine compartment front crossmember, then
remove the bonnet (see Chapter 11).
5Whenever you disconnect any vacuum
lines, coolant and emissions hoses, wiring
loom connectors, earth straps and fuel lines
as part of the following procedure, always
label them clearly, so that they can be
correctly reassembled.
6Unplug the two electrical connectors,disconnect the vacuum hose (where fitted)
and disconnect the crankcase breather hose
from the cylinder head cover, then remove the
complete air cleaner assembly, with the air
mass meter, the resonator and the plenum
chamber (see Chapter 4).
7Equalise the pressure in the fuel tank by
removing the filler cap, then undo the fuel
feed and return lines connecting the engine to
the chassis (see Chapter 4). Plug or cap all
open fittings (see illustration).
8Disconnect the accelerator cable from the
throttle linkage as described in Chapter 4 -
where fitted, also disconnect the cruise
control actuator cable (see Chapter 12).
Secure the cable(s) clear of the
engine/transmission.
9Releasing its wire clip, unplug the power
steering pressure switch electrical connector,
then unbolt the power steering high-pressure
pipe and the earth lead from the cylinder head
rear support plate/engine lifting eye (see
illustrations).

(only the one hose - there is no need to
disconnect the second hose running to
the fuel pressure regulator) (see
illustration).
(b) One from the union on the inlet manifold’s
left-hand end (see illustration).
(c) The braking system vacuum servo unit
hose - from the inlet manifold (see
Chapter 9 for details).
(d) Also disconnect the vacuum hoses from
the Exhaust Gas Recirculation system
components - one from the EGR valve,
two from the EGR pipe (note that these
last two are of different sizes, as are their
pipe stubs, so that they can only be
connected the correct way round).
(e) While you are there, trace the vacuum line
from the pulse-air filter housing over the
top of the transmission, and disconnect it
by pulling the plastic pipe out of the
rubber hose just beneath the bulkhead-
mounted pulse-air solenoid valve (see
illustration).
(f) Secure all these hoses so that they won’t
get damaged as the engine/transmission
is removed.
11Unbolt the engine/transmission-to-body
earth lead from the transmission’s top surface
(see illustration). Disconnect the speed-
ometer drive cable (see Chapter 12) and
secure it clear of the engine/transmission.
12Where the vehicle is fitted with manual
transmission, disconnect the clutch cable (seeChapter 8). Where automatic transmission is
fitted, disconnect the selector cable (see
Chapter 7, Part B). Secure the cable clear of
the engine/transmission.
13Marking or labelling all components as
they are disconnected (see paragraph 5
above), disconnect the engine wiring loom
from the body as follows:
(a) Starting at the left-hand side of the engine
compartment, release and unplug the
three large electrical connectors clipped
to the suspension mounting - note the
wire clips fitted to some connectors (see

(b) Disconnect and/or release the battery-to-
starter motor wiring, noting the single
connector which must be unplugged.
(c) Unplug the electrical connector(s) to
disconnect the vehicle speed sensor,
oxygen sensor and, where fitted, the oil
level sensor wiring - unclip the connectors
to release the wiring where necessary.
(d) Work along the loom to the bulkhead,
unclipping the loom and unplugging the
various bulkhead-mounted components
connected into it, until you reach the
right-hand side of the engine
compartment (see illustration).
(e) Carefully prise the power steering fluid
reservoir upwards out of its clip on the
suspension mounting, then unscrew the
ECU connector’s retaining bolt and
unplug the connector (see illustration).

14Unbolt both parts of the exhaust manifold
heat shield; unclip the coolant hose to allow
the upper part to be withdrawn.
15Remove the auxiliary drivebelt (see
Chapter 1).
16Unbolt the power steering pump (see
Chapter 10); secure it as far as possible
(without disconnecting the system’s hoses)
clear of the engine/transmission.
17Raise the vehicle and support it securely
on axle stands, then remove the front
roadwheels. Drain the cooling system and (if
the engine is to be dismantled) drain the
engine oil and remove the oil filter (see
Chapter 1). Also drain the transmission as
described in the relevant Part of Chapter 7.
18Withdraw the lower part of the exhaust
manifold heat shield.
19Unscrew the nuts to disconnect the
exhaust system front downpipe from the
manifold, then unhook all the system’s rubber
mountings and withdraw the complete
exhaust system from under the vehicle (see
Chapter 4 for details).
20Where the vehicle is fitted with manual
transmission, mark their positions, then
disconnect the gearchange linkage and
transmission support rods from the rear of the
transmission. Unscrew the retaining nuts, and
withdraw the gear linkage heat shield from the
underbody. Unbolt the rear end of the linkage
from the underbody, swivel the linkage around
to the rear, and tie it to the underbody (see
Chapter 7, Part A, for details).
21Disconnect both anti-roll bar links from
their respective suspension strut - note the
flexible brake hose bracket attached to each
link stud - and both track rod ends from their
steering knuckles. Unfasten the clamp bolt
securing each front suspension lower arm
balljoint to its steering knuckle (see Chap-
ter 10 for details). Check that both balljoints
can be released from the knuckle assemblies
when required, but leave them in place for thetime being, secured by the clamp bolts if
necessary.
22Where the vehicle is fitted with air
conditioning, unbolt the accumulator/
dehydrator from the subframe; secure it as far
as possible (without disconnecting the
system’s hoses) clear of the engine/
transmission.
Warning: Do not disconnect the
refrigerant hoses.
23Unbolt the steering gear from the
subframe; if the bolts are not accessible from
above, a Ford service tool will be required to
reach them from underneath the vehicle (see
Chapter 10 for details).
24Unscrew the two bolts securing the power
steering system pipes to the right-hand side
of the subframe.
25Hold the radiator in its raised position, by
inserting split pins through the holes in the
rear of the engine compartment front
crossmember and into the radiator’s upper
mounting extensions. Unbolt the radiator
mounting brackets from the subframe; note
that they are handed, and are marked to
ensure correct refitting (see illustrations).
Collect and store the bottom mounting
rubbers for safekeeping, noting which way up
they are fitted.
26Unbolt the engine/transmission rear
mounting from the subframe - where the
vehicle is fitted with automatic transmission, a
separate damper may be fitted beneath the
subframe, which must be unbolted to reach
the mounting’s fasteners. Where the vehicle is
fitted with manual transmission, also unscrew
the mounting centre bolt, and unbolt the
mounting bracket from the transmission.
27Unscrew the engine/transmission front
mounting centre bolt, and unbolt the
mounting from the subframe, noting the
location of the wiring connector bracket.
28Use white paint or similar (do not use a
sharp-pointed scriber, which might break the
underbody protective coating and cause
rusting) to mark the exact relationship of the
subframe to the underbody. Unscrew the four
mounting bolts from the subframe (note their
different-sized washers - see also illus-tration 4.47A) and allow the subframe to hang
down on the suspension lower arm balljoints.
Disconnect the balljoints one at a time from
the steering knuckle assemblies (see Chap-
ter 10) and lower the subframe to the ground;
withdraw the subframe from under the
vehicle.
29Marking or labelling all components as
they are disconnected (see paragraph 5
above) and catching as much as possible of
the escaping coolant in the drain tray,
disconnect the cooling system hoses and
pipes as follows - refer to Chapter 3 for further
details, if required:
(a) Remove the radiator top hose.
(b) Remove the (heater) hose running from
the thermostat to the engine
compartment bulkhead union.
(c) Disconnect from the thermostat the hose
running to the expansion tank - secure the
hose clear of the working area.
(d) Disconnect from the thermostat the
coolant hose/pipe which runs to the
radiator bottom hose.
(e) Disconnect the radiator bottom hose from
the radiator union, from the (sump) heater
coolant pipe and from the water pump
union - secure the hose clear of the
working area.
(f) Unbolt the (heater) coolant pipe from the
sump, trace the pipe/hose round to the
engine compartment bulkhead union,
disconnecting (where fitted) the oil cooler
hoses from the cooler unions, then
remove it.
(g) Unless the vehicle has air conditioning
fitted, secure the radiator as far forwards
as possible while it is in its raised position;
if air conditioning is fitted, remove the
radiator completely (see Chapter 3).
30Where the vehicle is fitted with air
conditioning, unplug the compressor’s
electrical connector, and unbolt the
compressor from the engine (see
