then an ordinary socket extension bar and an
angle gauge, to tighten the cylinder head
bolts in the stages given in the Specifications
Section of this Chapter (see illustrations).
Note:Once tightened correctly, following this
procedure, the cylinder head bolts do not
require check-tightening, and must notbe re-
torqued.
33Refit the hydraulic tappets (if removed),
the camshafts, their oil seals and pulleys (see
Sections 10, 11, 12 and 13, as appropriate).
Temporarily refit the crankshaft pulley, and
rotate the crankshaft clockwise to return the
pulley notches to the position described in
paragraph 8 of Section 10.
34Refit the timing belt and covers, checking
the camshaft alignment (valve timing) and
setting the timing belt tension, as described in
Section 10.
35The remainder of reassembly is the
reverse of the removal procedure, noting the
following points:
(a) Tighten all fasteners to the torque wrench
settings specified.
(b) When reassembling the
engine/transmission right-hand mounting,
renew the self-locking nuts, and do not
allow the mounting to twist as the middle
two of the bracket’s six nuts are
tightened.
(c) Refill the cooling system, and top-up the
engine oil.
(d) Check all disturbed joints for signs of oil
or coolant leakage, once the engine has
been restarted and warmed-up to normal
operating temperature.
Removal
Note:To carry out this task with the
engine/transmission installed in the vehicle
requires the assistance of at least one person,
plus the equipment necessary to raise and
support the front of the vehicle (high enough
that the sump can be withdrawn from
underneath), and to lift and support the
complete engine/transmission unit 2 to 3 inches from its mountings while the vehicle
is raised. Precise details of the procedure will
depend on the equipment available - the
following is typical.
The full procedure outlined below must be
followed, so that the mating surfaces can be
cleaned and prepared to achieve an oil-tight
joint on reassembly, and so that the sump
can be aligned correctly; depending on your
skill and experience, and the tools and
facilities available, it may be that this task can
be carried out only with the engine removed
from the vehicle.
Note that the sump gasket must be
renewed whenever it is disturbed.
1With the vehicle parked on firm level
ground, open the bonnet and disconnect the
battery negative (earth) lead - see Chapter 5,
Section 1.
2Drain the engine oil, then clean and refit the
engine oil drain plug, tightening it to the
specified torque wrench setting. Although not
strictly necessary as part of the dismantling
procedure, owners are advised to remove
and discard the oil filter, so that it can be
renewed with the oil (see Chapter 1).
3Drain the cooling system (see Chapter 1).
4Disconnect the radiator bottom hose from
the radiator union and from the (heater)
coolant pipe. Unbolt the coolant pipe from
the sump; if they will prevent sump removal,
disconnect or release the coolant hoses from
the oil cooler unions (where fitted).
5Unscrew the two bolts securing the powersteering system pipes to the right-hand side
of the subframe.
6Unplug the electrical connector(s) to
disconnect the oxygen sensor and, where
fitted, the oil level sensor wiring - unclip the
connectors to release the wiring where
necessary.
7Where the vehicle is fitted with automatic
transmission, trace the fluid cooler lines from
the transmission to the radiator, and release
them from any clips etc, so that they have as
much movement as possible.
8Remove the auxiliary drivebelt cover (see
Chapter 1).
9Unscrew the nuts to disconnect the
exhaust system front downpipe from the
manifold, then either unhook all the system’s
rubber mountings and withdraw the complete
exhaust system from under the vehicle, or
remove only the downpipe/catalytic converter
(see Chapter 4 for details).
10Unscrew the sump-to-transmission bolts,
also any securing the engine/transmission
lower adaptor plate.
11Unplugging 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).
12Take the weight of the engine/
transmission unit using the lifting eyes
provided on the cylinder head; bolt on

additional lifting eyes where required (see
illustration). Remove completely the
engine/transmission front mounting, unscrew
the rear mounting’s centre bolt, and unbolt
the left-hand mounting from the body.
Unscrew the six nuts securing the right-hand
mounting bracket, and withdraw the bracket.
13Being careful to watch the wiring, coolant
hoses, fluid cooler pipes or gearchange
linkage and transmission support rods (where
appropriate), and the radiator electric cooling
fan, to ensure that nothing is trapped,
stretched or damaged, lift the
engine/transmission unit by 2 to 3 inches and
support it securely.
14Progressively unscrew the sump retaining
bolts. Break the joint by striking the sump
with the palm of the hand, then lower the
sump and withdraw it with the
engine/transmission lower adaptor plate; note
the presence of any shims between the sump
and transmission.
15Remove and discard the sump gasket;
this must be renewed as a matter of course
whenever it is disturbed.
16While the sump is removed, take the
opportunity to remove the oil pump pick-up/
strainer pipe and to clean it (see Section 16).
Refitting
17On reassembly, thoroughly clean and
degrease the mating surfaces of the cylinder
block/crankcase and sump, then use a cleanrag to wipe out the sump and the engine’s
interior. If the oil pump pick-up/strainer pipe
was removed, fit a new gasket and refit the
pipe, tightening its screws to the specified
torque wrench setting. Fit the new gasket to
the sump mating surface so that the gasket
fits into the sump groove (see illustration).
18If the sump is being refitted with the
engine/transmission still connected and in the
vehicle, proceed as follows:
(a) Check that the mating surfaces of the
sump, the cylinder block/crankcase and
the transmission are absolutely clean and
flat. Any shims found on removal of the
sump must be refitted in their original
locations.
(b) Apply a thin film of suitable sealant (Ford
recommend Hylosil 102) to the junctions
of the cylinder block/crankcase with the
oil pump and the crankshaft left-hand oil
seal carrier. Without delay - the sump
bolts must be fully tightened within 10 to
20 minutes of applying the sealant - offer
up the sump and engine/transmission
lower adaptor plate, and refit the bolts,
tightening them lightly at first (see
illustration).
(c) Ensuring that the engine/transmission
lower adaptor plate is correctly located,
firmly press the sump against the
transmission, and tighten the
transmission-to-sump (ie, engine) bolts to
the specified torque wrench setting.(d) Without disturbing the position of the
sump, and working in a diagonal
sequence from the centre outwards,
tighten the sump bolts to the specified
torque wrench setting.
(e) Proceed to paragraph 20.
19If the sump is being refitted with the
engine and transmission separated (in or out
of the vehicle), proceed as follows:
(a) Apply a thin film of suitable sealant (Ford
recommend Hylosil 102) to the junctions
of the cylinder block/crankcase with the
oil pump and the crankshaft left-hand oil
seal carrier (see illustration). Without
delay - the sump bolts must be fully
tightened within 10 to 20 minutes of
applying the sealant - offer up the sump
to the cylinder block/crankcase, and
insert the sump bolts, tightening them
lightly at first.
(b) Using a suitable straight edge to check
alignment across the flat-machined faces
of each, move the sump as necessary so
that its left-hand face - including any
shims found on removal - is flush with
that of the cylinder block/crankcase (see
illustration). Without disturbing the
position of the sump, and working in a
diagonal sequence from the centre
outwards, tighten the sump bolts to the
specified torque wrench setting.
(c) Check again that both faces are flush
before proceeding; if necessary, unbolt
the sump again, clean the mating
surfaces, and repeat the full procedure to
ensure that the sump is correctly aligned.
(d) If it is not possible to achieve exact
alignment by moving the sump, shims are
available in thicknesses of 0.25 mm
(colour-coded yellow) or 0.50 mm (colour-
coded black) to eliminate the discrepancy
(see illustration).
20The remainder of reassembly is the
reverse of the removal procedure, noting the
following points.
(a) Tighten all fasteners to the torque wrench
settings specified.
(b) Always renew any self-locking nuts
disturbed on removal.
(c) Lower the engine/transmission unit into
place, and reassemble the rear, left-hand

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

inner wing panel, release the engine
wiring loom and refit the power steering
fluid reservoir.
(g) Secure the engine wiring loom neatly to
the engine/transmission so that it cannot
be damaged as the unit is removed from
the vehicle.
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
illustration). Secure it as far as possible
(without disconnecting the system’s hoses)
clear of the engine/transmission.
Warning: Do not disconnect the
refrigerant hoses.

31Where the vehicle is fitted with manual
transmission, disconnect the driveshafts from
the transmission as follows, referring to
Chapter 8 for further details when required:
(a) Unscrew the nuts securing the right-hand
driveshaft support bearing, and withdraw
the heat shield.
(b) Pull the right-hand driveshaft out of the
transmission; be prepared to catch any
spilt oil.
(c) Secure the driveshaft clear of the
engine/transmission - remember that the
unit is to be lowered out of the vehicle -
and ensure that the inner joint is not
turned through more than 18°.
(d) Prise the left-hand driveshaft out of the
transmission - again, be prepared for oil
spillage. Secure the driveshaft clear of the
engine/transmission, and ensure that its
inner joint is not turned through more than
18°.
32Where the vehicle is fitted with automatic
transmission, proceed as follows, referring to
Chapter 7, Part B and to Chapter 8 for further
details when required:
(a) Unscrew its centre bolt, then unbolt the
engine/transmission rear mounting
bracket from the transmission.
(b) Disconnect the fluid cooler pipe from the
rear of the transmission, and secure it
clear of the unit.
(c) Prise the left-hand driveshaft out of the
transmission; be prepared to catch any
spilt oil.
(d) Secure the driveshaft clear of the
engine/transmission - remember that the
unit is to be lowered out of the vehicle -
and ensure that the inner joint is not
turned through more than 18°.
(e) Unscrew the nuts securing the right-hand
driveshaft support bearing, and withdraw
the heat shield.
(f) Pull the right-hand driveshaft out of the
transmission - again, be prepared for oil
spillage. Secure the driveshaft clear of the
engine/transmission, and ensure that its
inner joint is not turned through more than
18°.
(g) Disconnect the fluid cooler pipe from the
front of the transmission, and secure it
clear of the unit.
33The engine/transmission unit should now
be hanging on the right- and left-hand
mountings only, with all components which
connect it to the rest of the vehicle
disconnected or removed and secured well
clear of the unit. Make a final check that this is
the case, then ensure that the body is
securely supported, high enough to permit the
withdrawal of the engine/transmission unit
from underneath; allow for the height of the
engine dolly, if used.
34Take the weight of the engine/
transmission unit, using the lifting eyes
provided on the cylinder head. Unscrew the
six nuts securing the right-hand mounting
bracket, then the three nuts securing the left-
hand bracket. Warning: Do not put any part of
your body under the vehicle, or
under the engine/transmission
unit, when they are supported only by a
hoist or other lifting equipment.
35Lower the engine/transmission to the
ground, and withdraw it from under the
vehicle (see illustration).
36Referring to the relevant part of Chapter 7,
separate the transmission from the engine.
37While the engine/transmission is removed,
check the mountings; renew them if they are
worn or damaged. Similarly, check the
condition of all coolant and vacuum hoses
and pipes (see Chapter 1); components that
are normally hidden can now be checked
properly, and should be renewed if there is
any doubt at all about their condition. Where
the vehicle is fitted with manual transmission,
take the opportunity to overhaul the clutch
components (see Chapter 8). It is regarded by
many as good working practice to renew the
clutch assembly as a matter of course,
whenever major engine overhaul work is
carried out. Check also the condition of all
components (such as the transmission oil
seals) disturbed on removal, and renew any
that are damaged or worn.
Refitting
38Refitting is the reverse of the removal
procedure, noting the following points.
Tighten all fasteners to the torque wrench
settings given; where settings are not quoted
in the Specifications Sections of the two Parts
of this Chapter, refer to the Specifications
Section of the relevant Chapter of this manual.
39In addition to the points noted in
paragraph 37 above, always renew any
circlips and self-locking nuts disturbed on
removal.
40Where wiring, etc, was secured by cable
ties which had to be cut on removal, ensure
that it is secured with new ties on refitting.
41With all overhaul operations completed,
refit the transmission to the engine as
described in Chapter 7.
42Manoeuvre the engine/transmission unit
under the vehicle, attach the hoist, and lift the
unit into position until the right- and left-hand
mountings can be reassembled; tighten the
(new) nuts only lightly at this stage. Do not yet
release the hoist; the weight of the
engine/transmission unit must not be taken by
the mountings until all are correctly aligned.
43Using new circlips, and ensuring that the
inner joints are not twisted through too great
an angle (see Chapter 8), refit the driveshafts.
Where the vehicle is fitted with manual
transmission, the procedure is the reverse of
that outlined in paragraph 31 above. Where
the vehicle is fitted with automatic
transmission, proceed as follows, referring to
Chapter 7, Part B and to Chapter 8 for further
details when required:
(a) Refit the left-hand driveshaft.
(b) Using the clips provided to ensure that
they are correctly routed, and tighteningthe couplings to the specified torque
wrench setting where possible, reconnect
the fluid cooler pipes, first to the rear,
then to the front, of the transmission.
(c) Refit the right-hand driveshaft to the
transmission, refit the heat shield, and
tighten the support bearing nuts to the
specified torque wrench setting.
(d) Refit the engine/transmission rear
mounting bracket to the transmission,
tightening the bolts to the torque wrench
setting specified, then refit the mounting,
tightening the centre bolt only lightly at
this stage.
44Where the vehicle is fitted with air
conditioning, do not forget to refit the
compressor; tighten the bolts to the specified
torque wrench setting, and plug in its
electrical connector.
45Using the marks and notes made on
removal, refit the cooling system hoses.
Where they are left disconnected or unclipped
for the time being, do not forget to secure
them at the appropriate moment during the
reassembly procedure. Refit the radiator (if
removed), using split pins to secure it in the
raised position.
46Offer up the subframe one side at a time,
and hold it by securing the suspension lower
arm balljoints to the steering knuckle
assemblies. Refit the subframe bolts, ensuring
that the washers are refitted correctly, and
tightening the bolts only lightly at this stage.
47The subframe must now be aligned on the
underbody. Ford specify the use of service
tool 15-097, which is a pair of tapered guides,
with attachments to hold them in the
subframe as it is refitted. However, since the
working diameter of these tools is 20.4 mm,
and since the corresponding aligning holes in
the subframe and underbody are respectively
21 mm and 22 mm in diameter, there is a
significant in-built tolerance possible in the
subframe’s alignment, even if the correct tools
are used. If these tools are not available, you
can align the subframe by eye, centring the
subframe aligning holes on those of the
underbody, and using the marks made on
removal for assistance. Alternatively, you can
align the subframe using a tapered drift (such
as a clutch-aligning tool), or even a deep

48Once the subframe is aligned as precisely
as possible, tighten its bolts to the specified
torque wrench setting without disturbing its
position. Recheck the alignment once all the
bolts are securely tightened.
49With the subframe aligned and securely
fastened, the engine/transmission unit must
now be positioned precisely, before the
mountings can be reassembled. Ford specify
the use of service tool 21-172; this is a fixture
bolted to the subframe in place of the
engine/transmission front mounting, so that
when the mounting’s centre bolt is refitted, it
is held 60 mm above the subframe’s top
surface, and offset 20 mm to the rear of the
mounting’s subframe bolt holes (centres). DIY
mechanics are advised to obtain the Ford
tool; the only alternative is to have a copy
fabricated (see illustration).
50Fasten the tool to the subframe in place of
the engine/transmission front mounting, and
lightly tighten the mounting’s centre bolt. Refit
the engine/transmission mountings in the
following sequence:
(a) Tighten the left-hand mounting’s nuts to
the specified torque wrench setting - do
not allow the mounting to twist as it is
tightened (see illustration).
(b) Tighten the right-hand mounting’s four
bracket-to-engine nuts to the specified
torque wrench setting.(c) Slowly release the hoist so that the weight
of the engine/transmission unit is taken by
the mountings.
(d) Tighten the right-hand mounting’s two
bracket-to-mounting nuts to the specified
torque wrench setting - do not allow the
mounting to twist as it is tightened (see
illustration).
(e) Reassemble the engine/transmission rear
mounting, tightening the fasteners to the
specified torque wrench settings; tighten
the centre bolt last.
(f) Refit the steering gear to the subframe; if
the Ford service tool is used to tighten the
bolts from underneath the vehicle (see
Chapter 10 for details), note that a torque
wrench which can tighten in an anti-
clockwise direction will be required.
(g) Unbolt the special tool from the front
mounting, refit the mounting - do not
forget the wiring connector bracket - and
tighten first the mounting’s bolts/nuts,
then its centre bolt, to their respective
specified torque wrench settings (see
illustrations).
51Refit the bottom mounting rubbers to the
radiator - ensure that both are the correct way
up - then refit the radiator mounting brackets
to the subframe, ensuring that each is
returned to its correct (marked) location, and
tightening the bolts to the torque wrench
setting specified. Remove the split pins, and
secure the coolant hose connections (where
necessary).
52Refit the air conditioning accumulator/
dehydrator (where appropriate) to the
subframe.
53Tighten the two bolts securing the power
steering system pipes to the right-hand side
of the subframe.
54Fasten each front suspension lower arm
balljoint and track rod end to their respective
steering knuckles, and both anti-roll bar links
to their respective suspension strut. Note the
flexible brake hose bracket attached to each
link stud (see Chapter 10 for details).
55Where the vehicle is fitted with manual
transmission, swivel the linkage around to the
front, tighten its rear fasteners, then refit the

3•2 Cooling, heating and air conditioning systems
Engine cooling system
All vehicles covered by this manual employ
a pressurised engine cooling system with
thermostatically-controlled coolant circu-
lation. A water pump mounted on the drivebelt
end of the cylinder block/crankcase pumps
coolant through the engine. The coolant flows
around each cylinder and toward the
transmission end of the engine. Cast-in
coolant passages direct coolant around the
inlet and exhaust ports, near the spark
plug areas and close to the exhaust valve
guides.
A wax pellet type thermostat is located in a
housing at the transmission end of the engine.
During warm-up, the closed thermostat
prevents coolant from circulating through the
radiator. Instead, it returns through the
coolant metal pipe running across the front of
the engine to the radiator bottom hose and
the water pump. The supply to the heater is
made from the rear of the thermostat housing.
As the engine nears normal operating
temperature, the thermostat opens and allows
hot coolant to travel through the radiator,
where it is cooled before returning to the
engine.
The cooling system is sealed by a pressure-
type filler cap in the expansion tank. The
pressure in the system raises the boiling point
of the coolant, and increases the cooling
efficiency of the radiator. When the engine is
at normal operating temperature, the coolant
expands, and the surplus is displaced into the
expansion tank. When the system cools, the
surplus coolant is automatically drawn back
from the tank into the radiator.
Warning: DO NOT attempt to
remove the expansion tank filler
cap, or to disturb any part of the
cooling system, while it or the
engine is hot, as there is a very great risk
of scalding. If the expansion tank filler cap
must be removed before the engine and
radiator have fully cooled down (even
though this is not recommended) the
pressure in the cooling system must first
be released. Cover the cap with a thick
layer of cloth, to avoid scalding, and slowly
unscrew the filler cap until a hissing sound
can be heard. When the hissing hasstopped, showing that pressure is
released, slowly unscrew the filler cap
further until it can be removed; if more
hissing sounds are heard, wait until they
have stopped before unscrewing the cap
completely. At all times, keep well away
from the filler opening.
Warning: Do not allow antifreeze
to come in contact with your
skin, or with the painted surfaces
of the vehicle. Rinse off spills
immediately with plenty of water. Never
leave antifreeze lying around in an open
container, or in a puddle in the driveway or
on the garage floor. Children and pets are
attracted by its sweet smell, but antifreeze
is fatal if ingested.
Warning: If the engine is hot, the
electric cooling fan may start
rotating even if the engine is not
running, so be careful to keep
hands, hair and loose clothing well clear
when working in the engine compartment.
Heating system
The heating system consists of a blower fan
and heater matrix (radiator) located in the
heater unit, with hoses connecting the heater
matrix to the engine cooling system. Hot
engine coolant is circulated through the
heater matrix. When the heater temperature
control on the facia is operated, a flap door
opens to expose the heater box to the
passenger compartment. When the blower
control is operated, the blower fan forces air
through the unit according to the setting
selected.
Air conditioning system
See Section 11.
Warning: Do not allow antifreeze to come in
contact with your skin, or with the painted
surfaces of the vehicle. Rinse off spills
immediately with plenty of water. Antifreeze is
highly toxic if ingested. Never leave antifreeze
lying around in an open container, or in
puddles on the floor; children and pets are
attracted by its sweet smell, and may drink it.
Check with local authorities about disposing
of used antifreeze - many have collection
centres which will see that antifreeze is
disposed of safely.The cooling system should be filled with a
water/ethylene glycol-based antifreeze
solution, of a strength which will prevent
freezing down to at least -25°C, or lower if the
local climate requires it. Antifreeze also
provides protection against corrosion, and
increases the coolant boiling point.
The cooling system should be maintained
according to the schedule described in
Chapter 1. If antifreeze is used that is not to
Ford’s specification, old or contaminated
coolant mixtures are likely to cause damage,
and encourage the formation of corrosion and
scale in the system. Use distilled water with
the antifreeze, if available - if not, be sure to
use only soft water. Clean rainwater is
suitable.
Before adding antifreeze, check all hoses
and hose connections, because antifreeze
tends to leak through very small openings.
Engines don’t normally consume coolant, so if
the level goes down, find the cause and
correct it.
The exact mixture of antifreeze-to-water
which you should use depends on the
relative weather conditions. The mixture
should contain at least 40% antifreeze, but
not more than 70%. Consult the mixture
ratio chart on the antifreeze container
before adding coolant. Hydrometers are
available at most automotive accessory
shops to test the coolant. Use antifreeze
which meets the vehicle manufacturer’s
specifications.
Note:Refer to the warnings given in Section 1
of this Chapter before starting work.
1If the checks described in Chapter 1 reveal
a faulty hose, it must be renewed as follows
(see illustration).
2First drain the cooling system (see Chap-
ter 1); if the antifreeze is not due for renewal,
the drained coolant may be re-used, if it is
collected in a clean container.
3To disconnect any hose, use a pair of pliers
to release the spring clamps (or a screwdriver
to slacken screw-type clamps), then move
them along the hose clear of the union.
Carefully work the hose off its stubs. The
hoses can be removed with relative ease
when new - on an older car, they may have
stuck.
