9Extract the bearing shells, and recover the
thrustwashers, keeping them identified for
location.
10The crankshaft and bearings can be
examined and if necessary renovated.
11Commence refitting as follows(see
illustration).
12Wipe the bearing shell locations in the
crankcase, and the crankshaft journals with a
soft non-fluffy rag.
13If the old main bearing shells are to be
renewed (not to do so is a false economy,
unless they are virtually new) fit the five upper
halves of the main bearing shells to their
locations in the crankcase.
14Fit the thrustwashers to the centre main
bearing location, using a little grease to retain
them if necessary. The oil grooves in the
thrustwashers must face outwards (ie facing
the crankshaft webs). Note that where
standard thrustwashers have been fitted in
production, the centre main bearing is
unmarked, but if oversize (0.38 mm)
thrustwashers have been fitted, the centre
main bearing will carry a yellow paint mark.
15Lubricate the crankshaft journals and the
upper and lower main bearing shells with
clean engine oil, then carefully lower the
crankshaft into the crankcase.
16Lubricate the crankshaft main bearing
journals again, and then fit the main bearing caps
in their correct locations, with the arrows on the
caps pointing towards the front of the engine.
17Fit the main bearing cap bolts, noting that
the studded bolts secure bearing caps Nos 3
and 5.
18Lightly tighten all the securing bolts, then
progressively tighten all bolts to the specified
torque.
19Check that the crankshaft rotates freely.
Some stiffness is to be expected with newcomponents, but there must be no tight spots
or binding.
20Check that the crankshaft endfloat is
within the specified limits by inserting a feeler
blade between the centre crankshaft web and
the thrustwashers.
21Refit the sump mounting plate to the front
of the cylinder block, and tighten the securing
bolts to the specified torque.
22Carefully wind a thin layer of tape around
the rear edge of the crankshaft to protect the
oil seal lips as the rear oil seal is installed.
23Refit the crankshaft rear oil seal housing,
using a new gasket, and tighten the securing
bolts to the specified torque.
24Install the new oil seal with reference to
Section 24.
25With the oil seal installed, carefully pull the
tape from the edge of the crankshaft.
26Refit the pistons and connecting rods as
described previously in this Chapter.
27Refit the flywheel/driveplate, and the
timing chain and crankshaft sprocket.
Proceed as described in Part A, Section 27
of this Chapter, noting that the production
bearing undersizes are indicated as follows.
Yellow or red paint marks on crankshaft —
standard diameter main bearing journals.
Green line on crankshaft front counterweight
— main bearing journals 0.25 mm
undersize.
Green spot on counterweight — big-end
bearing journals 0.25 mm undersize.
Refer to Part A, Section 25 of this Chapter,
but note that the connecting rod bolts should
be renewed on reassembly, and when
renewing the cylinder head bolts, the latest
type bolts with hexagonal heads should
always be used.
Proceed as described in Part A, Section 35
of this Chapter, noting the following points.
a)If the cylinder head has been removed,
pay particular attention to the note at the
beginning of Section 18.
b)If removed during any dismantling
operations, new flywheel driveplate bolts
and connecting rod bolts must be used.
c)After reassembling the main engine
components, refer to paragraph 3 of
Section 14 and refit the ancillary
components listed.Refer to Part A, Section 51 of this Chapter,
but note that when the engine is first started, a
metallic tapping noise may be heard. This is
due to the timing chain tensioner plunger
assembly taking time to pressurize with oil,
resulting in a temporarily slack chain. The
noise should stop after a short time, once oil
pressure has built up.
1When engine performance is down, or if
misfiring occurs which cannot be attributed to
the ignition or fuel system, a compression test
can provide diagnostic clues. If the test is
performed regularly it can give warning of
trouble before any other symptoms become
apparent.
2The engine must be at operating
temperature, the battery must be fully charged
and the spark plugs must be removed. The
services of an assistant will also be required.
3Disable the ignition system by dismantling
the coil LT feed. Fit the compression tester to
No 1 spark plug hole. (The type of tester which
screws into the spark plug hole is to be
preferred.)
4Have the assistant hold the throttle wide
open and crank the engine on the starter.
Record the highest reading obtained on the
compression tester.
5Repeat the test on the remaining cylinders,
recording the pressure developed in each.
6Desired pressures are given in the
Specifications. If the pressure in any cylinder
is low, introduce a teaspoonful of clean engine
oil into the spark plug hole and repeat the test.
7If the addition of oil temporarily improves
the compression pressure, this indicates that
bore or piston wear was responsible for the
pressure loss. No improvement suggests that
leaking or burnt valves, or a blown head
gasket, may be to blame.
8A low reading from two adjacent cylinders is
almost certainly due to the head gasket
between them having blown.
9On completion of the test, refit the spark
plugs and reconnect the coil LT feed.

3Recover the oil pump driveshaft, noting
which way round it is fitted.
4Recover the oil pump-to-block gasket.
2.4 & 2.9 litre engines
5Remove the sump.
6Unbolt the oil pump/inlet pipe assembly and
remove it then extract the driveshaft, which is
splined into the distributor shaft (see illustration).
1Remove the cylinder heads,the sump and
the oil pump.
2Check that the big-end bearing caps and
connecting rods have identification marks. This
is to ensure that the correct caps are fitted to the
correct connecting rods and at reassembly are
fitted in their correct cylinder bores. Note that
the pistons have an arrow (or notch) marked on
the crown to indicate the forward facing side.
3Remove the big-end nuts and place to one
side in the order in which they are removed.
4Pull off the big-end caps, taking care to
keep them in the right order and the correct
way round. Also ensure that the shell bearings
are kept with their respective connecting rods
unless they are being renewed.5To remove the shell bearings, press the
bearing on the side opposite the groove in
both the connecting rod and the cap, and the
bearing will slide out.
6Withdraw the pistons and connecting rods
upwards out of the cylinder bores.
1Remove the cylinder heads and pushrods.
2Remove the tappets from their bores, using
a pencil magnet or by inserting a piece of bent
brass wire through the lubrication holes (see
illustration).
3Remove the timing cover and the camshaft
gear.
4Remove the two bolts which secure the
camshaft thrust plate. Withdraw the camshaft,
thrust plate and spacer ring.
5The intermediate plate may now be
removed after removing the retaining bolts.
Note the oil seals on the timing cover locating
dowels, which must also be removed.
1The engine must be removed from the
vehicle for this task.
2Remove the flywheel/driveplate, timing
cover and crankshaft gear, and the pistons
and connecting rods, as described in the
preceding Sections. (If no work is to be done
on the pistons, they need not actually be
pushed out of their bores.)
3Make sure that the main bearing caps carry
identification marks, then remove the bolts
and lift off the caps. Tap the caps with a soft-
faced mallet if necessary to free them.
4Note that the rear main bearing cap also
retains the crankshaft rear oil seal, and that the
shells for No 3 main bearing have thrust
flanges to control crankshaft endfloat.
5Lift out the crankshaft. Do not drop it, it is
heavy.
6Recover the upper half main bearing shells
from their seats in the crankcase, again
keeping them in order if they are to be re-
used.
7Remove the old oil seal from the rear of the
crankshaft.
Refer to Part A, Section 23 of this Chapter.1Disconnect the battery negative lead.
2Remove the crankshaft pulley (and damper,
when fitted).
3Extract the old oil seal by levering it out with
a hooked tool.
4Clean out the seal seat in the timing cover.
Lubricate the new seal and fit it, lips inwards. Seat
the seal with a piece of tube or a large socket. (If
available, Ford tool 21-063 and a non-damper
type pulley may be used to seat the seal.)
5Lubricate the sealing surface of the pulley or
damper and refit it.
6The remainder of refitting is a reversal of the
removal procedure. Check the engine oil level
on completion.
Refer to Part A, Section 18 of this Chapter.
Refer to Part A, Section 25 of this Chapter.
New cylinder head bolts are not required if
they are of the hexagon head type. Torx type
bolts must be renewed. The two types of
cylinder head bolt must not be mixed on the
same engine.
1Tap out the roll pin from one end of the
rocker shaft and remove the spring washer
(see illustration).
2Slide the rocker arms, rocker supports and
springs off the rocker shaft. Keep them in the
correct order so that they can be reassembled
in the same position (see illustration).

3Examine the rocker shaft and rocker arms for
wear. If the rocker arm surface that contacts the
valve stem is considerably worn, renew the
rocker arm. If it is worn slightly step-shaped it
may be cleaned up with a fine oil stone.
4Oil the parts and reassemble them on their
shafts in the original order. With both rocker
shafts fitted the oil holes must face
downwards to the cylinder heads. This
position is indicated by a notch on one end
face of the rocker shaft (see illustration).
Inspect the tappets for scuffing, surface wear
or other damage. Renew them if necessary. It is
good practice to renew the tappets if a new
camshaft is being fitted.Check the pushrods for bending by rolling
them on a flat surface. Straighten or renew as
necessary. Also check the pushrod ends for
wear or damage.
1If there is excessive wear in the camshaft
bearings they will have to be renewed. As the
fitting of new bearings requires special tools
this should be left to your local Ford dealer.
2The camshaft may show signs of wear on
the bearing journals or cam lobes. The main
decision to take is what degree of wear
necessitates renewing the camshaft, which is
expensive. Scoring or damage to the bearing
journals cannot be removed by regrinding;
renewal of the camshaft is the only solution.
3The cam lobes may show signs of ridging or
pitting on the high points. If ridging is slight
then it may be possible to remove it with a fine
oil stone or emery cloth. The cam lobes,
however, are surface hardened and once the
hard skin is penetrated wear will be very rapid.
4Excessive endfloat of the camshaft may be
remedied by fitting a thicker spacer and/or
thrust plate - see Specifications.
5Excessive backlash in the camshaft drive
gears (timing gears), which will have been
noticed before dismantling by virtue of the
characteristic growling noise, can only be
remedied by renewing the gears.1Clean the dirt and oil off the cylinder heads.
Remove the carbon deposits from the
combustion chambers and valve heads with a
scraper or rotary wire brush.
2Remove the valves by compressing the
valve springs with a suitable valve spring
compressor and lifting out the collets. Release
the valve spring compressor and remove the
valve spring retainer, spring and valve (see
illustrations).Note: When removing and
refitting the valve spring take care not to
damage the valve stem when pressing down
the valve spring retainer to remove or refit the
collets. If the stem gets damaged the sealing
will be ineffective and result in excessive oil
consumption and wear of the valve guides.
3Remove the valve stem oil seals from the
valve guides and discard them.
4With the valves removed clean out the
carbon from the ports.
5Examine the heads of the valves and the
valve seats for pitting and burning. If the
pitting on valve and seat is slight it can be
removed by grinding the valves and seats
together with coarse, and then fine, valve
grinding paste.
6Severe pitting or burning of the valves
probably means that they must be renewed.
Badly burnt valve seats can be recut, or
inserts can be fitted, by a Ford dealer or other
specialist.
7Check the valve guides for wear by inserting
the valve into its guide until the valve stem is
flush with the end of the guide, then checking
the play at the valve head(see illustration).
Movement in excess of 0.6 mm (0.024 in)
means that the clearance between guide and
stem is excessive.
8Valve guide wear is dealt with by reaming
the guides to a known oversize and fitting new
valves with oversize stems. Again, this is a
dealer or specialist task.

3Refit the crankshaft gear, if removed, using
a length of tube to drive it home.
4Position the camshaft and crankshaft so
that their keyways are facing each other(seeillustration).Slide the camshaft gear onto the
camshaft, rotating the shafts slightly if
necessary so that the marks on the two gears
are aligned. Remember that there are two
marks on the crankshaft gear.
5Fit the camshaft gear retaining bolt and
washer(see illustration).Tighten the bolt to
the specified torque.
6Apply sealant to the mating faces of the

Cooling system
The cooling system is of pressurised type
and includes a front mounted crossflow
radiator, belt-driven water pump, temperature-
sensitive thermo-viscous fan (on DOHC
models, an electrically-operated cooling fan is
fitted, operated by a switch in the thermostat
housing), wax type thermostat, and an
expansion and degas tank.
The radiator matrix is of copper and brass
construction and the end tanks are of plastic.
On automatic transmission models the right-
hand side end tank incorporates the
transmission oil cooler.
The thermostat is located behind the water
outlet elbow at the front of the cylinder head
on OHCmodels, and on the front of the water
pump on V6 models. Its purpose is to ensure
rapid engine warm-up by restricting the flow of
coolant in the engine when cold, and also to
assist in regulating the normal operating
temperature of the engine.
The expansion tank incorporates a pressure
cap which effectively pressurises the cooling
system as the coolant temperature rises,
thereby increasing the boiling point of the
coolant. The tank also has a further degas
function. Any accumulation of air bubbles in
the coolant, in particular in the thermostat
housing and the radiator, is returned to the
tank and released in the air space thus
maintaining the efficiency of the coolant.
On models fitted with the auxiliary warning
system, the expansion tank contains a level
sensor which operates a warning light if the
coolant level falls significantly.
When the engine is started from cold, the
water pump circulates coolant around the
cylinder block, cylinder head(s) and inlet
manifold. The warm coolant passes through
the automatic choke housing (when
applicable) and through the heater matrix
before returning to the engine. As the coolant
expands, the level in the expansion tank rises.
Circulation of coolant through the radiator is
prevented while the thermostat is shut. When
the coolant reaches the predeterminedtemperature the thermostat opens and hot
water passes through the top hose to the top
of the radiator. As the water circulates down
through the radiator, it is cooled by the
passage of air past the radiator when the car is
in forward motion, supplemented by the action
of the thermo-viscous fan when necessary.
Having reached the bottom of the radiator, the
water is now cool and the cycle is repeated.
Circulation of water continues through the
expansion tank, inlet manifold and heater at all
times; the heater temperature control being by
an air flap.
The thermo-viscous fan is controlled by the
temperature of air behind the radiator. When
the air temperature reaches a predetermined
level, a bi-metallic coil commences to open a
valve within the unit and silicon fluid is fed
through a system of vanes. Half of the vanes
are driven directly by the water pump and the
remaining half are connected to the fan blades.
The vanes are arranged so that drive is
transmitted to the fan blades in relation to the
drag or viscosity of the fluid, and this in turn
depends on ambient temperature and engine
speed. The fan is therefore only operated when
required, and compared with direct drive type
fan represents a considerable improvement in
fuel economy, drivebelt wear and fan noise.
Air conditioning
Air conditioning is fitted as standard on
Scorpio models and is optionally available on
some other models. In conjunction with the
heater, the system enables any reasonable air
temperature to be achieved inside the car, it
also reduces the humidity of the incoming air,
aiding demisting even when cooling is not
required.
The refrigeration side of the air conditioning
system functions in a similar way to a
domestic refrigerator. A compressor, belt-
driven from the crankshaft pulley, draws
refrigerant in its gaseous phase from an
evaporator. The compressed refrigerant
passes through a condenser where it loses
heat and enters its liquid phase. After
dehydration the refrigerant returns to the
evaporator where it absorbs heat from air
passing over the evaporator fins. The
refrigerant becomes a gas again and the cycle
is repeated.Various subsidiary controls and sensors
protect the system against excessive
temperature and pressures. Additionally,
engine idle speed is increased when the
system is in use to compensate for the
additional load imposed by the compressor.
Precautions
Antifreeze mixture
Antifreeze mixture is poisonous. Keep it out
of reach of children and pets. Wash splashes
off skin and clothing with plenty of water.
Wash splashes off vehicle paintwork to avoid
discolouration.
Antifreeze/water mixture must be renewed
every two years to preserve its anti-corrosive
properties. In climates where antifreeze
protection is unnecessary, a corrosion
inhibitor may be used instead - consult a Ford
dealer. Never run the engine for long periods
with plain water as coolant. Only use the
specified antifreeze, as inferior brands may not
contain the necessary corrosion inhibitors, or
may break down at high temperatures.
Antifreeze containing methanol is particularly
to be avoided, as the methanol evaporates.
The specified mixture is 45 to 50%
antifreeze and 50 to 55% clean soft water (by
volume). Mix the required quantity in a clean
container.
Air conditioning refrigerant
Although the refrigerant is not itself toxic, in
the presence of a naked flame (or a lighted
cigarette) it forms a highly toxic gas. Liquid
refrigerant spilled on the skin will cause
frostbite. If refrigerant enters the eyes, rinse
them with a dilute solution of boric acid and
seek medical advice immediately.
In view of the above points, and of the need
for specialised equipment for evacuating and
recharging the system, any work which
requires the disconnection of a refrigerant line
must be left to a specialist.
Do not allow refrigerant lines to be exposed
to temperatures above 110°C (230°F) - eg
during welding or paint drying operations and
do not operate the air conditioning system if it
is known to be short of refrigerant, or further
damage may result.

1Drain the radiator. There is no need to drain
the cylinder block. On DOHC engines the
electric cooling fan assembly must be removed
to gain the clearance to remove the radiator.
2Disconnect the top and bottom hoses from
the radiator by slackening the hose clips and
pulling off the hoses with a twisting motion
(see illustrations). Do not use excessive force
- the radiator side tanks are made of plastic.
3On OHCmodels, disconnect the small hose
running from the expansion tank to the radiator.
4On automatic transmission models, clean
around the transmission fluid cooler unions on
the radiator and disconnect them (seeillustration). Be prepared for fluid spillage;
plug or cap the cooler lines to keep dirt out.
5On models with air conditioning, disconnect
the auxiliary fan thermo-switch. If the thermo-
switch is mounted in the radiator, remove It.
6Remove the upper half of the fan shroud by
removing the two bolts and two clips (see
illustration), and the lower half which is
secured by two bolts.
7Release the two radiator top mounting clips
by pulling out the plastic plugs (see illustration).
8Raise and support the front of the vehicle.
Support the radiator and remove the two
bottom mounting bolts (see illustration).
9Carefully lower the radiator slightly to free
the top mountings, then remove it from under
the vehicle.
10If a new radiator is being fitted, transfer the
fan shrouds and mountings from the old one.
11Refit by reversing the removal operations,
then refill the cooling system.
12On automatic transmission models, check
the transmission fluid level.
1If the radiator has been removed because of
suspected blockage, reverse-flush it.
2Clean dirt and debris from the radiator fins,
using an air jet, or water and a soft brush. Be
careful not to damage the fins, or cut your
fingers. 3A radiator specialist can perform a “flow
test” on the radiator to establish whether an
internal blockage exists.
4A leaking radiator must be referred to a
specialist for permanent repair. Do not attempt
to weld or solder a leaking radiator, as
damage to the plastic parts may result.
5In an emergency, minor leaks from the
radiator can be cured by using a radiator
sealant while the radiator is in situ.
SOHC engines
1Disconnect the battery negative lead.
2Drain the cooling system. As it is not
necessary to completely drain the radiator, the
bottom hose can be disconnected from the
water pump.
3Disconnect the top hose from the
thermostat housing at the front of the cylinder
head (see illustration).
4Unscrew the bolts and remove the housing
and gasket (see illustration).
5Using a screwdriver, prise the retaining clip
from the housing, and extract the thermostat
and sealing ring (see illustrations).
6Clean the thermostat housing and cylinder
head mating surfaces. Obtain a new gasket for
reassembly, and if necessary a new sealing
ring too.
7Refit by reversing the removal operations.

20Checking and adjustment should be
completed within 30 seconds of the meter
readings stabilising. If this has not been
possible, run the engine at 3000 rpm for 15
seconds, then allow the engine to idle. Re-
check the CO content and carry out further
adjustments if necessary.
21On completion of adjustment, stop the
engine and disconnect the tachometer and the
exhaust gas analyser. Refit the cover to the
adjustment screw.
2.4 & 2.9 litre V6 engines
22As with the 2.8 V6, idle speed is
electronically controlled. Basic idle speed
adjustment can only be carried out by a Ford
dealer using special equipment.
23On models not equipped with a catalytic
converter, mixture adjustment can be carried
out as described above.
24On models equipped with a catalytic
converter, the mixture is controlled by the EEC IV
module and no manual adjustment is possible.
SOHC and V6 engines
1Disconnect the battery negative lead.
2Free the throttle position sensor multi-plug
from its clip. On the OHCmodels this is below
the idle speed control valve, on the underside
of the inlet manifold; on V6 engines it is
located below the throttle valve housing.
3Relieve the locktabs and unbolt the throttle
position sensor (see illustration). Pull the
sensor off the throttle valve shaft, disconnect
the multi-plug and remove the sensor.
4Do not rotate the centre part of the sensor
beyond its normal range of movement, or
damage may result.
5When refitting, line up the flat on the throttle
valve shaft with the flat on the centre of the
sensor. Make sure that the sensor is the right
way round and fit it over the shaft.
6Fit and tighten the two bolts and secure it
with the locktabs.
7Reconnect and secure the multi-plug, then
reconnect the battery.
DOHC engine
8Disconnect the battery negative lead.
9Free the throttle position sensor wiring plug
from the retaining clip located on the
underside of the throttle body. Disconnect the
wiring plug halves by releasing the locktabs
and pulling on the plug halves, not the wiring
(see illustration).
10Unscrew the two sensor securing screws,
and withdraw the sensor from the throttle
shaft.
11Refitting is a reversal of removal, noting
that the sensor fits with the wiring at the
bottom, and ensuring that the sensor
actuating arm engages correctly with the
throttle spindle.1On DOHC models, disconnect the battery
negative lead.
2Free the throttle position sensor wiring plug
from the retaining clip located on the
underside of the throttle body. Disconnect the
wiring plug halves by releasing the locktabs
and pulling on the plug halves, not the wiring.
3Disconnect the throttle cable and (where
necessary) the speed control cable from the
throttle linkage.
4Loosen the securing clip, and disconnect
the air inlet hose from the throttle body.
5Unscrew the four securing bolts and
withdraw the throttle body from the inlet
manifold along with the gasket.
6Refitting is a reversal of removal, bearing in
mind the following points.
a)Ensure that the mating faces of the
throttle body and the inlet manifold are
clean, and fit a new gasket.
b)On completion, adjust the throttle cable
and where necessary, adjust the speed
control cable so that there is only a small
amount of slack in the cable.
c)Where applicable, check and if necessary
adjust the idle mixture.
SOHC and all V6 engines
1Disconnect the battery negative lead.
2Disconnect the multi-plug from the idle
speed control valve by prising up the retaining
lug and pulling the plug, not the wires (see
illustration).
3Remove the two securing nuts (OHC) or
bolts (V6) and withdraw the valve (see
illustration). Recover the gasket.
4If necessary, the solenoid can be separated
from the valve block by removing the two
screws to enable the parts to be cleaned.
Contamination or air leaks in this area will
cause unstable idling. After careful cleaning,
the parts can be reassembled.
5Refit the valve, using a new gasket, and
tighten the retaining nuts or bolts. Reconnect
the multi-plug and the battery.
6Start the engine and check that the idle is
steady. Bring the engine to operating
temperature, then switch on all possible electrical
loads (headlights, heated screens, heater blower
etc) and check that the idle remains steady. This
confirms that the valve is working.
