1993 FORD MONDEO coolant

contamination with oil or coolant. Renew the
belt if there is the slightest doubt about its
condition. As a safety measure, the belt must
be renewed as a matter of course at the
intervals given in Chapter 1; if its history is
unknown, the belt should be renewed
irrespective of its apparent condition
whenever the engine is overhauled. Similarly,
check the tensioner spring (where fitted),
renewing it if there is any doubt about its
condition. Check also the toothed pulleys for
signs of wear or damage, and ensure that the
tensioner and guide pulleys rotate smoothly
on their bearings; renew any worn or
damaged components. If signs of oil or
coolant contamination are found, trace the
source of the leak and rectify it, then wash
down the engine timing belt area and related
components, to remove all traces of oil or
coolant.
17On reassembly, temporarily refit the
crankshaft pulley, to check that the pulley
notches and sump rib are aligned as
described in paragraph 8 above, then ensure
that both camshafts are aligned at TDC by
the special tool (paragraph 10). If the engine
is being reassembled after major dismantling,
both camshaft toothed pulleys should be free
to rotate on their respective camshafts; if the
timing belt alone is being renewed, both
pulleys should still be securely fastened.
18A holding tool will be required to prevent
the camshaft toothed pulleys from rotating
while their bolts are slackened and
retightened; either obtain Ford service tool15-030A, or fabricate a substitute as follows.
Find two lengths of steel strip, one
approximately 600 mm long and the other
about 200 mm, and three bolts with nuts and
washers; one nut and bolt forming the pivot of
a forked tool, with the remaining nuts and
bolts at the tips of the “forks”, to engage with
the pulley spokes as shown in the
accompanying illustrations. Note:Do not use
the camshaft aligning tool (whether genuine
Ford or not) to prevent rotation while the
camshaft toothed pulley bolts are slackened
or tightened; the risk of damage to the
camshaft concerned and to the cylinder head
is far too great. Use only a forked holding tool
applied directly to the pulleys, as described.
19If it is being fitted for the first time, screw
the timing belt tensioner spring retaining pin
into the cylinder head, tightening it to the
specified torque wrench setting. Unbolt the
tensioner, hook the spring on to the pin and
the tensioner backplate, then refit the
tensioner, engaging its backplate on the
locating peg (see illustrations).
20In all cases, slacken the tensioner bolt (if
necessary), and use an Allen key inserted into
its centre to rotate the tensioner clockwise as
far as possible against spring tension, then
retighten the bolt to secure the tensioner (see
illustration).
21Fit the timing belt; if the original is being
refitted, ensure that the marks and notes
made on removal are followed, so that the
belt is refitted the same way round, and to run
in the same direction. Starting at thecrankshaft toothed pulley, work anti-
clockwise around the camshaft toothed
pulleys and tensioner, finishing off at the rear
guide pulley. The front run, between the
crankshaft and the exhaust camshaft toothed
pulleys, mustbe kept taut, without altering
the position either of the crankshaft or of the
camshaft(s) - if necessary, the position of the
camshaft toothed pulleys can be altered by
rotating each on its camshaft (which remains
fixed by the aligning tool). Where the pulley is
still fastened, use the holding tool described
in paragraph 18 above to prevent the pulley
from rotating while its retaining bolt is
slackened - the pulley can then be rotated on
the camshaft until the belt will slip into place;
retighten the pulley bolt.
22When the belt is in place, slacken the
tensioner bolt gently until the spring pulls the
tensioner against the belt; the tensioner
should be retained correctly against the
timing belt inner shield and cylinder head, but
must be just free to respond to changes in
belt tension (see illustration).
23Tighten both camshaft toothed pulley
bolts (or check that they are tight, as
applicable) and remove the camshaft aligning
tool. Temporarily refit the crankshaft pulley,
and rotate the crankshaft through two full
turns clockwise to settle and tension the
timing belt, returning the crankshaft (pulley
notches) to the position described in
paragraph 8 above. Refit the camshaft
aligning tool; it should slip into place as
described in paragraph 10. If all is well,
proceed to paragraph 26 below.
24If one camshaft is only just out of line, fit
the forked holding tool to its toothed pulley,
adjust its position as required, and check that
any slack created has been taken up by the
tensioner; rotate the crankshaft through two
further turns clockwise, and refit the camshaft
aligning tool to check that it now fits as it
should. If all is well, proceed to paragraph 26
below.
25If either camshaft is significantly out of
line, use the holding tool described in
paragraph 18 above to prevent its pulley from
rotating while its retaining bolt is slackened -
the camshaft can then be rotated (gently and
carefully, using an open-ended spanner) until

23If using Ford’s recommended procedure,
fit new oil seals to the camshafts as
described in paragraph 5 of Section 12.
24Using the marks and notes made on
dismantling to ensure that each is refitted to
its original camshaft, refit the toothed pulleys
to the camshafts, tightening the retaining
bolts loosely (see illustration). Slip the timing
belt back onto the pulleys (refer to para-
graph 21 of Section 10) and tighten the bolts
securely - use the forked holding tool
described in paragraph 18 of Section 10.
25The remainder of the reassembly
procedure, including checking the camshaft
alignment (valve timing) and setting the timing
belt tension, is as described in paragraphs 17
to 27 of Section 10.
Removal
Note:The following text assumes that the
cylinder head will be removed with both inlet
and exhaust manifolds attached; this
simplifies the procedure, but makes it a bulky
and heavy assembly to handle - an engine
hoist will be required, to prevent the risk of
injury, and to prevent damage to any delicate
components as the assembly is removed and
refitted. If it is wished first to remove the
manifolds, proceed as described in Sections
6 and 7 of this Chapter; amend the following
procedure accordingly.1Relieve the fuel system pressure (see
Chapter 4).
2With the vehicle parked on firm level
ground, open the bonnet and disconnect the
battery negative (earth) lead - see Chapter 5,
Section 1.
3Whenever 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.
4Unplugging 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).
5Equalise 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.
6Disconnect the accelerator cable from the
throttle linkage as described in Chapter 4 -where fitted, disconnect also the cruise control
actuator cable (see Chapter 12). Secure the
cable(s) clear of the engine/transmission.
7Unbolt the power steering high-pressure
pipe from the cylinder head rear support
plate/engine lifting eye, and from the front
support plate/pump bracket. Releasing its
wire clip, unplug the power steering pressure
switch electrical connector, then unbolt the
earth lead from the cylinder head rear support
plate/engine lifting eye.
8Remove the three screws securing the
wiring “rail” to the rear of the manifold.
Releasing its wire clip, unplug the large
electrical connector (next to the fuel pressure
regulator) to disconnect the engine wiring from
the main loom (see illustration). Unplug the
electrical connectors on each side of the
ignition coil, and the single connector from
beneath the front of the thermostat housing, to
disconnect the coil and coolant temperature
gauge sender wiring (see illustration).
9Marking or labelling them as they are
unplugged, disconnect the vacuum hoses as
follows:
(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).
(b) One from the union on the inlet manifold’s
left-hand end (see illustration).
(c) The braking system vacuum servo unit
hose (see Chapter 9 for details).
(d) Disconnect all vacuum hoses from the
Exhaust Gas Recirculation system
components - one from the EGR valve
and 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.)
10Unbolt both parts of the exhaust manifold
heat shield; unclip the coolant hose to allow the
upper part to be withdrawn. Either remove the
dipstick and tube, or swing them out of the way.
11Unscrew the single bolt securing the
pulse-air filter housing to the engine/
transmission front mounting bracket, then
disconnect its vacuum hose.
12Drain the cooling system (see Chapter 1).
13Disconnect all coolant hoses from the
thermostat housing (see illustration).

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).

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

and right-hand mountings. 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.
(d) Fitting the Ford service tool in place of the
front mounting, tighten the
engine/transmission mounting fasteners
to their specified torque wrench settings,
and in the sequence described in Part B
of this Chapter, Section 4, paragraphs 49
and 50.
(e) Refill the cooling system (see Chapter 1).
(f) Refill the engine with oil, remembering
that you are advised to fit a new filter (see
Chapter 1).
(g) Check for signs of oil or coolant leaks
once the engine has been restarted and
warmed-up to normal operating
temperature.
Removal
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. Note, however, that the oil pumppressure relief valve can be removed with the
engine in situ - see paragraph 8.
In addition to the new pump gasket and
other replacement parts required, read
through Section 15, and ensure that the
necessary tools and facilities are available.
1Remove the timing belt (see Section 10).
2Withdraw the crankshaft toothed pulley
and the thrustwasher behind it, noting which
way round the thrustwasher is fitted (see
Section 11).
3Remove the sump (see Section 15).
4Undo the screws securing the oil pump
pick-up/strainer pipe to the pump, then
unscrew the nut and withdraw the oil pump
pick-up/strainer pipe. Discard the gasket.
5Unbolt the pump from the cylinder
block/crankcase (see illustration). Withdraw
and discard the gasket, and remove the
crankshaft right-hand oil seal. Thoroughly
clean and degrease all components,
particularly the mating surfaces of the pump,
the sump, and the cylinder block/crankcase.
Inspection
6Unscrew the Torx screws, and remove the
pump cover plate; noting any identification
marks on the rotors, withdraw the rotors (see
illustration).
7Inspect the rotors for obvious signs of wear
or damage, and renew if necessary; if either
rotor, the pump body, or its cover plate are
scored or damaged, the complete oil pump
assembly must be renewed.
8The oil pressure relief valve can bedismantled, if required, without disturbing the
pump. With the vehicle parked on firm level
ground, apply the handbrake securely and
raise its front end, supporting it securely on
axle stands. Remove the front right-hand
roadwheel and auxiliary drivebelt cover (see
Chapter 1) to provide access to the valve.
9Unscrew the threaded plug, and recover
the valve spring and plunger (see
illustrations). If the plug’s sealing O-ring is
worn or damaged, a new one must be
obtained, to be fitted on reassembly.
10Reassembly is the reverse of the
dismantling procedure; ensure the spring and
valve are refitted the correct way round, and
tighten the threaded plug securely.
Refitting
11The oil pump must be primed on
installation, by pouring clean engine oil into it,
and rotating its inner rotor a few turns.
12Using grease to stick the new gasket in
place on the cylinder block/crankcase, and
rotating the pump’s inner rotor to align with
the flats on the crankshaft, refit the pump and
insert the bolts, tightening them lightly at first
(see illustration).
13Using a suitable straight edge and feeler
gauges, check that the pump is both centred
exactlyaround the crankshaft, and aligned
squarely so that its (sump) mating surface is
exactly the same amount - between 0.3 and
0.8 mm - below that of the cylinder block/
crankcase on each side of the crankshaft
(see illustration). Being careful not to disturb

the gasket, move the pump into the correct
position, and tighten its bolts to the specified
torque wrench setting.
14Check that the pump is correctly located;
if necessary, unbolt it again, and repeat the
full procedure to ensure that the pump is
correctly aligned.
15Fit a new crankshaft right-hand oil seal
(see Section 20).
16Using grease to stick the gasket in place
on the pump, refit the pick-up/strainer pipe,
tightening its screws and nut to their specified
torque wrench settings (see illustration).
17The remainder of reassembly is the
reverse of the removal procedure, referring to
the relevant text for details where required.
1Drain the cooling system (see Chapter 1).
Disconnect the coolant hoses from the oil
cooler.
2Unscrew the oil filter (see Chapter 1) -
catch any escaping oil in a drip tray.
3Unscrew the filter adaptor from the oil
pump, and withdraw the oil cooler; note how
its unions are aligned, and be prepared for oil
loss from the cooler.
4Refitting is the reverse of the removal
procedure, noting the following points:(a) Renew all O-rings and seals disturbed on
removal.
(b) Align the cooler’s unions as noted on
removal, and tighten the adaptor to the
specified torque wrench setting.
(c) Refill the cooling system (see Chapter 1).
(d) Refit the oil filter, then check the engine
oil level, and top-up as necessary (see
Chapter 1).
(e) Check for signs of oil or coolant leaks once
the engine has been restarted and warmed-
up to normal operating temperature.
1With the vehicle parked on firm level
ground, open the bonnet and disconnect the
battery negative (earth) lead - see Chapter 5,
Section 1.
2Raise the front of the vehicle, and support it
securely on axle stands.
3Undo the two screws, and remove the
sensor’s cover from the front of the sump
(see illustration).
4Unplug the wiring from the sensor (see
illustration). Where necessary, unplug the
electrical connector to disconnect the sensor
wiring, and unclip the connector to release
the wiring from the vehicle.
5Unscrew the sensor, and quickly plug the
sump aperture to minimise oil loss; note the
sensor’s seal.6Refitting is the reverse of the removal
procedure; renew the sensor’s seal if it is
worn or damaged, and tighten the sensor to
the specified torque wrench setting. Check
the engine oil level, and top-up as necessary
(see Chapter 1) - check for signs of oil leaks
once the engine has been restarted and
warmed-up to normal operating temperature.
1The switch is screwed into the rear of the
cylinder block, above the right-hand
driveshaft’s support bearing (see
illustration).
2With the vehicle parked on firm level
ground, open the bonnet and disconnect the
battery negative (earth) lead - see Chapter 5,
Section 1.
3Raise the front of the vehicle, and support it
securely on axle stands.
4Unplug the wiring from the switch, and
unscrew it; be prepared for some oil loss.
5Refitting is the reverse of the removal
procedure; apply a thin smear of suitable
sealant to the switch threads, and tighten it to
the specified torque wrench setting. Check
the engine oil level, and top-up as necessary
(see Chapter 1). Check for signs of oil leaks
once the engine has been restarted and
warmed-up to normal operating temperature.
Note:Don’t try to prise these seals out
without removing the oil pump or seal carrier -
the seals are too soft, and the amount of
space available is too small, for this to be
possible without considerable risk of damage
to the seal housing and/or the crankshaft
journal. Follow exactly the procedure given
below.

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).
10Marking or labelling all components as
they are disconnected (see paragraph 5
above), disconnect the vacuum hoses as
follows:

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.
