(a) One from the rear of the throttle housing
(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
illustration).
(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).

(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
Engine removal and general engine overhaul procedures 2B•7

socket spanner of suitable size (see
illustrations).
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

gear linkage heat shield. Reconnect the
gearchange linkage and transmission support
rods to the transmission, adjusting the linkage
using the marks made on removal (see
Chapter 7, Part A, for details).
56Re-install the remaining components and
fasteners in the reverse order of removal.
57Add coolant, engine oil and transmission
fluids as needed (see Chapter 1).
58Run the engine, and check for proper
operation and the absence of leaks. Shut off
the engine, and recheck the fluid levels.
59Remember that, since the front suspension
subframe and steering gear have been
disturbed, the wheel alignment and steering
angles must be checked fully and carefully as
soon as possible, with any necessary
adjustments being made. This operation is best
carried out by an experienced mechanic, using
proper checking equipment; the vehicle should
therefore be taken to a Ford dealer or similarly-
qualified person for attention.
1It is much easier to dismantle and work on
the engine if it is mounted on a portable engine
stand. These stands can often be hired from a
tool hire shop. Before the engine is mounted
on a stand, the flywheel/driveplate should be
removed (Part A of this Chapter, Section 21)
so that the stand bolts can be tightened into
the end of the cylinder block/crankcase.
2If a stand is not available, it is possible to
dismantle the engine with it mounted on
blocks, on a sturdy workbench or on the floor.
Be extra-careful not to tip or drop the engine
when working without a stand.
3If you are going to obtain a reconditioned
engine, all external components must be
removed first, to be transferred to the
replacement engine (just as they will if you are
doing a complete engine overhaul yourself).
Note:When removing the external
components from the engine, pay close
attention to details that may be helpful or
important during refitting. Note the fitted
position of gaskets, seals, spacers, pins,
washers, bolts and other small items.These
external components include the following:
(a) Alternator and brackets (Chapter 5).
(b) HT leads and spark plugs (Chapter 1).
(c) Thermostat and housing (Chapter 3).
(d) Dipstick tube.
(e) Fuel injection system components
(Chapter 4).
(f) All electrical switches and sensors - refer
to the appropriate Chapter.
(g) Inlet and exhaust manifolds (Part A of this
Chapter).
(h) Oil filter (Chapter 1).
(i) Engine/transmission mounting brackets
(Part A of this Chapter, Section 22).
(j) Flywheel/driveplate (Part A of this
Chapter, Section 21).
4If you are obtaining a “short” engine (whichconsists of the engine cylinder
block/crankcase, crankshaft, pistons and
connecting rods all assembled), then the
cylinder head, sump, oil pump, and timing belt
will have to be removed also.
5If you are planning a complete overhaul, the
engine can be dismantled and the internal
components removed in the following order.
(a) Inlet and exhaust manifolds (Part A of this
Chapter).
(b) Timing belt, toothed pulleys and
tensioner, and timing belt inner cover
(Part A of this Chapter).
(c) Cylinder head (Part A of this Chapter,
Section 14).
(d) Flywheel/driveplate (Part A of this
Chapter, Section 21).
(e) Sump (Part A of this Chapter, Section 15).
(f) Oil pump (Part A of this Chapter, Sec-
tion 16).
(g) Piston/connecting rod assemblies
(Section 9).
(h) Crankshaft (Section 10).
6Before beginning the dismantling andoverhaul procedures, make sure that you have
all of the correct tools necessary. Refer to the
introductory pages at the beginning of this
manual for further information.
Note:New and reconditioned cylinder heads
are available from the manufacturers, and
from engine overhaul specialists. Due to the
fact that some specialist tools are required for
the dismantling and inspection procedures,
and new components may not be readily
available (refer to Section 1 of this Part), it may
be more practical and economical for the
home mechanic to purchase a reconditioned
head, rather than to dismantle, inspect and
recondition the original head.
1Remove the camshafts and hydraulic
tappets (Part A of this Chapter, Section 13),
being careful to store the hydraulic tappets as
described (see illustration).

grinding or head resurfacing. Use
compressed air, if available, to blow out all the
oil holes and passages.
2Beginning at one end of the head, lubricate
and install the first valve. Apply molybdenum
disulphide-based grease or clean engine oil to
the valve stem, and refit the valve. Where the
original valves are being re-used, ensure that
each is refitted in its original guide. If new
valves are being fitted, insert them into the
locations to which they have been ground.
3Fit the plastic protector supplied with new
valve spring lower seat/stem oil seals to the
end of the valve stem, then put the new seal
squarely on top of the guide, and leave it
there; the action of refitting the valve spring
presses the lower seat/stem oil seal into place
(see illustration).
4Refit the valve spring and upper seat.
5Compress the spring with a valve spring
compressor, and carefully install the collets in
the stem groove. Apply a small dab of grease
to each collet to hold it in place if necessary
(see illustration). Slowly release the
compressor, and make sure the collets seat
properly.
6When the valve is installed, place the
cylinder head flat on the bench and, using a
hammer and interposed block of wood, tap
the end of the valve stem gently, to settle the
components.7Repeat the procedure for the remaining
valves. Be sure to return the components to
their original locations - don’t mix them up!
8Refit the hydraulic tappets (Part A of this
Chapter, Section 13).
Note:Always check first what replacement
parts are available before planning any
overhaul operation; refer to Section 1 of this
Part. A Ford dealer, 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.
Note:While this task is theoretically possible
when the engine is in place in the vehicle, in
practice, it requires so much preliminary
dismantling, and is so difficult to carry out due
to the restricted access, that owners are
advised to remove the engine from the vehicle
first. In addition to the new gaskets and other
replacement parts required, a hoist will be
needed. Alternatively, an adjustable engine
support bar, fitting into the water drainchannels on each side of the bonnet aperture,
and having a hook which will engage the
engine lifting eyes and allow the height of the
engine to be adjusted, could be used. Lifting
equipment such as this can be hired from
most tool hire shops - be sure that any such
equipment is rated well in excess of the
combined weight of the engine/transmission
unit.
1Remove the cylinder head (Part A of this
Chapter, Section 14).
2Bolt lifting eyes to suitable points on the
engine and transmission, then attach the
lifting equipment so that the engine/
transmission unit is supported securely.
3Remove the sump (Part A of this Chapter,
Section 15).
4Undo the screws securing the oil pump
pick-up/strainer pipe to the pump, then
unscrew the four nuts, and withdraw the oil
pump pick-up/strainer pipe and oil baffle (see
illustration).
5Temporarily refit the crankshaft pulley, so
that the crankshaft can be rotated. Note that
each piston/connecting rod assembly can be
identified by its cylinder number (counting
from the timing belt end of the engine) etched
into the flat-machined surface of both the
connecting rod and its cap. The numbers are
visible from the front (exhaust side) of the
engine. Furthermore, each piston has an
arrow stamped into its crown, pointing
towards the timing belt end of the engine. If
no marks can be seen, make your own before
disturbing any of the components, so that you
can be certain of refitting each
piston/connecting rod assembly the right way
round, to its correct (original) bore, with the
cap also the right way round (see
illustrations).
6Use your fingernail to feel if a ridge has
formed at the upper limit of ring travel (about a
quarter-inch down from the top of each
cylinder). If carbon deposits or cylinder wear
have produced ridges, they must be
completely removed with a special tool (see
illustration). Follow the manufacturer’s
instructions provided with the tool. Failure to
remove the ridges before attempting to

remove the piston/connecting rod assemblies
may result in piston ring breakage.
7Slacken each of the big-end bearing cap
bolts half a turn at a time, until they can be
removed by hand. Remove the No 1 cap and
bearing shell. Don’t drop the shell out of the
cap.
8Remove the upper bearing shell, and push
the connecting rod/piston assembly out
through the top of the engine. Use a wooden
hammer handle to push on the connecting
rod’s bearing recess. If resistance is felt,
double-check that all of the ridge was
removed from the cylinder.
9Repeat the procedure for the remaining
cylinders.
10After removal, reassemble the big-end
bearing caps and shells on their respective
connecting rods, and refit the bolts finger-
tight. Leaving the old shells in place until
reassembly will help prevent the bearing
recesses from being accidentally nicked or
gouged. New shells should be used on
reassembly.
11Don’t attempt to separate the pistons
from the connecting rods - see Section 12.
Note:The crankshaft can be removed only
after the engine/transmission has been
removed from the vehicle. It is assumed that
the transmission and flywheel/driveplate,
timing belt, cylinder head, sump, oil pump
pick-up/strainer pipe and oil baffle, oil pump,
and piston/connecting rod assemblies, have
already been removed. The crankshaft left-
hand oil seal carrier must be unbolted from
the cylinder block/crankcase before
proceeding with crankshaft removal.
1Before the crankshaft is removed, check
the endfloat. Mount a DTI (Dial Test Indicator,
or dial gauge) with the stem in line with the
crankshaft and just touching the crankshaft
(see illustration).
2Push the crankshaft fully away from the
gauge, and zero it. Next, lever the crankshaft
towards the gauge as far as possible, andcheck the reading obtained. The distance that
the crankshaft moved is its endfloat; if it is
greater than specified, check the crankshaft
thrust surfaces for wear. If no wear is evident,
new thrustwashers should correct the
endfloat; these are part of the No 3 (centre)
main bearing upper shell (see illustration).
3If no dial gauge is available, feeler gauges
can be used. Gently lever or push the
crankshaft all the way towards the right-hand
end of the engine. Slip feeler gauges between
the crankshaft and the right-hand face of the
No 3 (centre) main bearing to determine the
clearance (see illustration).
4Check the main bearing caps, to see if they
are marked to indicate their locations (see
illustration). They should be numbered
consecutively from the timing belt end of the
engine - if not, mark them with number-
stamping dies or a centre-punch. The caps will
also have an embossed arrow pointing to the
timing belt end of the engine. Noting the
different fasteners (for the oil baffle nuts) used on
caps 2 and 4, slacken the cap bolts a quarter-
turn at a time each, starting with the left- and
right-hand end caps and working toward the
centre, until they can be removed by hand.
5Gently tap the caps with a soft-faced
hammer, then separate them from the cylinder
block/crankcase. If necessary, use the bolts
as levers to remove the caps. Try not to drop
the bearing shells if they come out with the
caps.6Carefully lift the crankshaft out of the
engine. It may be a good idea to have an
assistant available, since the crankshaft is
quite heavy. With the bearing shells in place in
the cylinder block/crankcase and main
bearing caps, return the caps to their
respective locations on the block, and tighten
the bolts finger-tight. Leaving the old shells in
place until reassembly will help prevent the
bearing recesses from being accidentally
nicked or gouged. New shells should be used
on reassembly.
Note:Always check first what replacement
parts are available before planning any
overhaul operation; refer to Section 1 of this
Part. A Ford dealer, 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.

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.

sender’s electrical connector, and use a
jumper wire to connect the white/red wire to a
clean earth point (bare metal) on the engine.
Switch on the ignition without starting the
engine. If the gauge now indicates Hot, renew
the sender.
5If the gauge still does not work, the circuit
may be open, or the gauge may be faulty. See
Chapter 12 for additional information.
Removal
6Unbolt the resonator support bracket from
the engine compartment front crossmember.
Slacken the two clamp screws securing the
resonator to the air mass meter and plenum
chamber hoses, then swing the resonator up
clear of the thermostat housing (see Chap-
ter 4).
7Drain the cooling system (see Chapter 1).
8Disconnect the expansion tank coolant
hose and the radiator top hose from the
thermostat housing’s water outlet, then
disconnect the metal coolant pipe/hose from
the thermostat.
9Unplug the electrical connector from the
sender (see illustration).
10Unscrew the sender and withdraw it.
Refitting
11Clean as thoroughly as possible the
opening in the thermostat housing, then apply
a light coat of sealant to the sender’s threads.
Screw in the sender and tighten it to the
specified torque wrench setting, and plug in
its electrical connector.
12Reconnect the hoses and refit the
resonator, top-up the cooling system (see
Chapter 1) and run the engine. Check for
leaks and proper gauge operation.
Coolant temperature sensor
Testing
13Disconnect the battery negative (earth)
lead (see Chapter 5, Section 1).
14Unbolt the resonator support bracket
from the engine compartment front
crossmember. Slacken the two clamp screws
securing the resonator to the air mass meter
and plenum chamber hoses, then swing the
resonator up clear of the thermostat housing
(see Chapter 4).
15Unplug the electrical connector from the
sensor (see illustration).
16Using an ohmmeter, measure the
resistance between the sensor terminals.
Depending on the temperature of the sensor
tip, the resistance measured will vary, but
should be within the broad limits given in the
Specifications Section of this Chapter. If the
sensor’s temperature is varied - by removing
it (see below) and placing it in a freezer for a
while, or by warming it gently - its resistance
should alter accordingly.
17If the results obtained show the sensor to
be faulty, renew it.
18On completion, plug in the connector and
refit the resonator.
Removal
19Disconnect the battery negative (earth)
lead (see Chapter 5, Section 1).
20Unbolt the resonator support bracket
from the engine compartment front
crossmember. Slacken the two clamp screws
securing the resonator to the air mass meter
and plenum chamber hoses, then swing the
resonator up clear of the thermostat housing
(see Chapter 4).
21With the engine completely cool, remove
the expansion tank filler cap to release any
pressure, then refit the cap. Provided you
work swiftly and plug the opening as soon as
the sensor is unscrewed, coolant loss will thus
be minimised; this will avoid the draining of
the complete cooling system which would
otherwise be necessary (see Chapter 1).
22Unplug the electrical connector from the
sensor.
23Unscrew the sensor and withdraw it. If the
cooling system has not been drained, plug the
opening as quickly as possible.
Refitting
24Clean as thoroughly as possible the
opening in the thermostat housing, then apply
a light coat of sealant to the sensor’s threads.
Remove the material used to plug the sensor
hole (where applicable), and quickly install the
sensor to prevent coolant loss. Tighten the
sensor to the specified torque wrench setting,
and plug in its electrical connector.
25Refit the resonator, top-up the cooling
system (see Chapter 1) and run the engine,
checking for leaks.
Coolant low level switch
Testing
26The switch is a reed-type unit mounted in
the bottom of the cooling system expansion
tank, activated by a magnetic float. If the
coolant level falls to the “MIN” level or less,
the appropriate bulb lights in the warning
display.
27If the bulb fails to light during the 5-
second bulb test, check the bulb, and renew if
necessary as described in Chapter 12.
28To check the switch itself, unplug its
electrical connector, and use an ohmmeter to
measure the resistance across the switchterminals. With the float up, a resistance of
90 ohms should be measured; when it is
down, the resistance should increase to
approximately 150 kilohms.
29If the results obtained from the check are
significantly different from those expected,
the switch is faulty, and must be renewed.
30If the switch and bulb are proven to be
sound, the fault must be in the wiring or in the
auxiliary warning control assembly (see
Chapter 12).
Removal
31Disconnect the battery negative (earth)
lead (see Chapter 5, Section 1).
32Remove the expansion tank (see Sec-
tion 7).
33Unplug the switch electrical connector.
34Release the switch by twisting its retainer
anti-clockwise, then withdraw it.
Refitting
35Refitting is the reverse of the removal
procedure. Refill the cooling system (see
Chapter 1). Start the engine, and check for
coolant leaks when it is fully warmed-up.
Note:Refer to the warnings given in Section 1
of this Chapter before starting work.
Radiator
Removal
Note:If leakage is the reason for removing the
radiator, bear in mind that minor leaks can
often be cured using a radiator sealant with
the radiator in situ.
1Remove the radiator fan and shroud
assembly (see Section 5).
2Disconnect the bottom hose from the
radiator.
3If the vehicle has automatic transmission,
disconnect the fluid cooler lines, and plug the
lines and fittings.
4If the vehicle has air conditioning, unscrew
the condenser mounting nuts or bolts, detach
the condenser from the radiator, and tie it to
the engine compartment front crossmember.

Warning: Do not disconnect any
of the refrigerant hoses.
5Unbolt the radiator mounting brackets from
the subframe; note that they are handed, and
are marked to ensure correct refitting (see
illustration). Collect the bottom mounting
rubbers, noting which way up they are fitted,
and store them carefully.
6Carefully lower the radiator from the
vehicle, and withdraw it.
7With the radiator removed, it can be
inspected for leaks and damage. If it needs
repair, have a radiator specialist or dealer
service department perform the work, as
special techniques are required.
8Insects and dirt can be removed from the
radiator with a garden hose or a soft brush.
Don’t bend the cooling fins as this is done.
Refitting
9Refitting is the reverse of the removal
procedure. Be sure the mounting rubbers are
seated properly at the base of the radiator.
10After refitting, refill the cooling system
with the proper mixture of antifreeze and
water (see Chapter 1).
11Start the engine, and check for leaks.
Allow the engine to reach normal operating
temperature, indicated by the radiator top
hose becoming hot. Recheck the coolant
level, and add more if required.12If working on an vehicle with automatic
transmission, check and add transmission
fluid as needed (see Chapter 1).
Expansion tank
13With the engine completely cool, remove
the expansion tank filler cap to release any
pressure, then refit the cap.
14Disconnect the hoses from the tank,
upper hose first. As each hose is
disconnected, drain the tank’s contents into a
clean container. If the antifreeze is not due for
renewal, the drained coolant may be re-used,
if it is kept clean.
15Unscrew the tank’s two mounting bolts
and withdraw it, unplugging the coolant low
level switch electrical connector (where fitted).
16Wash out the tank, and inspect it for
cracks and chafing - renew it if damaged.
17Refitting is the reverse of the removal
procedure. Refill the cooling system with the
proper mixture of antifreeze and water (see
Chapter 1), then start the engine and allow it
to reach normal operating temperature,
indicated by the radiator top hose becoming
hot. Recheck the coolant level and add more
if required, then check for leaks.
Note:Refer to the warnings given in Section 1
of this Chapter before starting work.
Check
1A failure in the water pump can cause
serious engine damage due to overheating.
2There are three ways to check the operation
of the water pump while it’s installed on the
engine. If the pump is defective, it should be
replaced with a new or rebuilt unit.
3With the engine running at normal operating
temperature, squeeze the radiator top hose. If
the water pump is working properly, a
pressure surge should be felt as the hose is
released. Warning: Keep your hands away
from the radiator electric
cooling fan blades!
4Remove the timing belt covers (see Chap-
ter 2, Part A). Water pumps are equipped with
weep or vent holes. If a failure occurs in the
pump seal, coolant will leak from the hole. In
most cases you’ll need an electric torch to
find the hole on the water pump from
underneath to check for leaks.
5If the water pump shaft bearings fail, there
may be a howling sound at the drivebelt end
of the engine while it’s running. Shaft wear
can be felt if the water pump pulley is rocked
up and down. Don’t mistake drivebelt
slippage, which causes a squealing sound, for
water pump bearing failure.
Removal and refitting
6Remove the timing belt and tensioner (see
Chapter 2, Part A). As noted in Chapter 2, if
the belt is fouled with coolant, it must be
renewed as a matter of course.
7Drain the cooling system (see Chapter 1).
8Disconnect the radiator bottom hose from
the pump union. It is easier to reach this union
if the power steering pump is unbolted and
moved aside as described in Chapter 10 (see
illustration). There is no need to disconnect
any of the power steering system hoses.
9Unbolt and remove the water pump (see
illustration). If the pump is to be renewed,
unbolt the timing belt guide pulleys, and
transfer them to the new pump.
10Clean the mating surfaces carefully; the
gasket must be renewed whenever it is
disturbed (see illustration).
11On refitting, use grease to stick the new
gasket in place, refit the pump, and tighten
the pump bolts to the specified torque wrench
setting.
12The remainder of the reassembly
procedure is the reverse of dismantling. Note
that a new tensioner spring and retaining pin
must be fitted if the timing belt has been
removed for the first time. Tighten all
fasteners to the specified torque wrench
settings, and refill the system with coolant as
described in Chapter 1.
