Cylinder head bolts on the V6 engine may
be conventional (hexagon-headed) or Torx
type. The appropriate Torx key will be needed
to deal with the latter.
Before dismantling the engine into its main
components, the following ancillaries can be
removed. The actual items removed, and the
sequence of removal, will depend on the work
to be done.
Distributor and bracket
Spark plugs
Inlet manifold and associated items
Exhaust manifolds
Clutch
Alternator and bracket
Oil pressure switch(see illustration) Temperature gauge sender
Engine bearer arms

Refer to Part A, Section 33 of this Chapter.
The crankcase ventilation system is very
simple. One hose joins the rear air inlet
trunking to the oil filler cap, and another hose
joins the left-hand rocker cover to the plenum
chamber. Filtered (and metered) air passes
through the oil filler cap into the engine, and is
extracted, along with any other fumes, via the
second hose. Refer to Chapter 1 for
maintenance of the system.
Refer to Part A, Section 35 of this Chapter
but disregard the reference to new cylinder
head bolts when these are of the conventional
(hexagon-headed) type. Only Torx type bolts
need to be renewed.
1Wipe the bearing shell locations in the
crankcase with a clean rag and fit the mainbearing upper half shells in position (see
illustration).
2Clean the main bearing shell locations and
fit the half shells in the caps.
3Fit the flanged shells to No 3 bearing.

those for caps 1 and 4.
10Tighten the main bearing cap bolts
progressively to the specified torque.
11Make sure that the crankshaft is free to
rotate. Some stiffness is to be expected withnew components, but there should be no tight
spots or binding.
12Press the crankshaft rear oil seal firmly
against the rear main bearing.
13Check the crankshaft endfloat, levering
the crankshaft back and forth and inserting
feeler blades between the crankshaft and No 3
main bearing (see illustration). Excessive
endfloat can only be due to wear of the
crankshaft or bearing shell flanges.
14Coat the rear main bearing cap sealing
wedges with sealant and press into position
with a blunt screwdriver(see illustration).The
rounded end of each wedge carries a red paint
mark, which must face the bearing cap.

Some trial and error may be involved in
achieving this.
19Lock the camshaft sprocket and tighten
the retaining bolt to the specified torque.
20Retract the chain tensioner. To do this,
insert the plunger (bevelled side entering), then
release the pawl with a small screwdriver
pushed into the hole in the tensioner body
(see illustration).21Compress the plunger/slipper and retain it
in the retracted position using a cable-tie or
similar. New chain tensioners are supplied
complete with a retainer (see illustration).
22Bolt the tensioner in position, at the same
time removing the plunger retainer. Tighten the
bolts to the specified torque.
23Locate a new gasket on the front face of
the engine.
24Renew the timing cover oil seal and apply
grease to the lips.
25Fit the timing cover, centre it and align it
with the sump mounting flange.
26Although a special tool (21-137) is
available for centring the cover, a piece of
plastic pipe, or a socket of suitable thickness,
will serve as an adequate substitute.
Alternatively measure the space between the
crankshaft nose and the timing cover damper
recess at several different points and adjust
the position of the cover until all the
measurements are equal. A strip of metal 14.0
mm wide will serve as a gauge if calipers are
not available (see illustrations).
27Tighten the timing cover bolts (see
illustration)and fit the Woodruff key (where
removed) for the vibration damper.
28Apply jointing compound to the front and
rear sump flange areas on the timing
cover/cylinder block and rear main bearing
cap. Make sure that the bearing surfaces are
perfectly clean. Checking that the rear tabs of
the gasket enter the recesses in the main
bearing cap, locate a new sump gasket on the
crankcase (see illustration).

1Check the cost and availability of spare parts
before deciding to dismantle the carburettor. If
the unit has seen much service, fitting a new or
reconditioned carburettor may prove more
satisfactory than any attempt at overhaul.
2Obtain a carburettor repair kit, which will
contain the necessary gaskets, diaphragms
and other renewable items.
3With the carburettor removed from the
vehicle, clean it thoroughly externally and
place it on a clean worksurface.
4 Referringto the exploded view of the
carburettor(see illustration),remove each
component part whilst making a note of its
fitted position. Make alignment marks on
linkages etc.
5Reassemble in the reverse order to
dismantling, using new gaskets, O-rings etc.
6To check the choke pull-down after
reassembly, position the fast idle screw on the
highest step of the cam. Press the pull-down
adjusting screw towards the pull-down
diaphragm and measure the choke valve
opening with a twist drill or gauge rod of the
specified diameter. Adjust if necessary using
a 2 mm Allen key (see illustration).
7After refitting the throttle damper, adjust its
position in the bracket so that with a 2 mm
(0.08 in) feeler blade inserted between the idle
speed adjusting screw and the throttle lever,
the damper plunger is just touching the
actuating lever(see illustration).
8Adjust the idle speed and mixture, and if
necessary the fast idle speed, after refitting the
carburettor.
9Recheck the throttle damper adjustment,
when applicable.
1This is not a routine operation. It should only
be necessary after overhaul, or when a new
carburettor is fitted.
2The idle speed and mixture must be
correctly set and the engine must be at
operating temperature.3Remove the air cleaner and plug the
manifold vacuum connection.
4With the engine running, position the fast
idle screw on the second highest step of the
fast idle cam(see illustration).Measure the
engine speed and compare it with that given in
the Specifications.
5If adjustment is necessary, remove the
tamperproof plug from the fast idle screw by
crushing it with pliers. Stop the engine and
open the throttle to gain access to the screw
with a small screwdriver. Turn the screw a
small amount clockwise to increase the speed,
anti-clockwise to reduce it, then reseat the
screw on the second highest step of the cam
and recheck the engine speed. Repeat as
necessary.
6Fit a new tamperproof cap where this is
required by law, then refit the air cleaner.
Idle speed cannot be adjusted in the usual
way on this carburettor, as it is controlled by
the ESC ll module.
If mixture adjustment is required, proceed
as described in Chapter 1, Section 16.
1Disconnect the battery negative lead.
2Remove the air cleaner.3Disconnect the choke and stepper motor
wiring. The stepper motor multi-plug locking
device must be depressed to release the plug
(seeillustration).
4Unclip the throttle arm from the throttle lever
and remove the throttle cable bracket.
5Disconnect the fuel hose from the
carburettor and plug it. If a crimped type hose
clip is fitted, cut it off and use a worm drive
clip when refitting.
6Disconnect the vacuum pipe(s) from the
carburettor, noting their connecting points if
there is any possibility of confusion.
7Remove the four carburettor-to-manifold
nuts. Check that nothing has been overlooked,
then lift off the carburettor. Recover the
gasket.
8Clean the carburettor and manifold mating
faces, being careful not to sweep dirt into the
manifold.
9Refit by reversing the removal operations. If
the stepper motor has been disturbed, refer to
Chapter 5, Section 19 for the initial
adjustment.
1Check the cost and availability of spare
parts before deciding to dismantle the
carburettor. If the unit has seen much service,
fitting a new or reconditioned carburettor may
prove more satisfactory than any attempt at
overhaul.
2Obtain a carburettor repair kit, which will
contain the necessary gaskets, diaphragms
and other renewable items.
3With the carburettor removed from the
vehicle, clean it thoroughly externally and
place it on a clean worksurface.
4 Referringto the exploded view of the
carburettor(see illustration),remove each
component part whilst making a note of its
fitted position. Make alignment marks on
linkages etc.
5Reassemble in the reverse order to
dismantling, using new gaskets, O-rings etc.
Be careful not to kink the diaphragms.

16Start the engine and note the engine
speed (rpm). The engine speed should
increase above the normal idle speed, and
should be as given in the Specifications.
17If the engine speed is not as specified,
remove the tamperproof plug from the top of
the throttle kicker housing, and turn the
adjustment screw to give the specified speed.
18On completion of adjustment, fit a new
tamperproof cap.
19Disconnect the tubing from the inlet
manifold, and reconnect the throttle kicker
vacuum hose.
20Refit the plastic shield and the air cleaner.
On 2.4 & 2.9 litre V6 models especially,
residual pressure will remain in the fuel lines
long after the vehicle was last used therefore
the fuel system must be depressurised before
any hose is disconnected; the system is
depressurised via the vent valve on the fuel
rail, noting that it may be necessary to depress
the valve several times before the pressure is
fully released. As an added precaution place a
rag over the valve as it is depressed to catch
any fuel which is forcibly expelled. Before
carrying out any operation on the fuel system
refer to the precautions given in Safety first! at
the beginning of this Manual and follow them
implicitly. Petrol is a highly dangerous and
volatile liquid and the precautions necessary
when handling it cannot be overstressed.
Access to the relays is obtained by
removing the facia top cover (crash pad).
The relays are located on the passenger
side(see illustration). Also see Chapter 13,
Section 16.
See Chapter 1, Section 41.
SOHC and 2.8 litre V6 engines
1Idle speed is controlled by the EEC IV
module and no direct adjustment is possible.
2Idle mixture adjustment should not be
necessary on a routine basis. After component
renewal or a similar circumstance it may be
checked and adjusted as follows.
3The engine must be at operating temperature.
The valve clearances must be correct, the air
cleaner element must be clean and the ignition
system must be in good condition.
4Connect an exhaust gas analyser (CO
meter) and a tachometer (rev. counter) to the
engine as instructed by their makers.
5Run the engine at 3000 rpm for 15 seconds,
then allow it to idle. Repeat the procedure
every 60 seconds until adjustment is
complete.
6With the engine idling after the 3000 rpm
burst, record the CO level when the reading
has stabilised. The desired value is given in the
Specifications.
7If adjustment is necessary, remove the
tamperproof plug from the mixture adjusting
screw on the underside of the vane airflow
meter (see illustration).
8On V6 models, note that adjustment should
first be carried out on the front airflow meter.The rear meter should only be adjusted if the
range of adjustment on the front meter is
insufficient.
9Turn the mixture adjusting screw with a
hexagon key until the CO level is correct (see
illustration).
10Stop the engine and disconnect the test
gear.
11Fit a new tamperproof plug if required.
DOHC engine
Note: Before carrying out any adjustments
ensure that the ignition timing and spark plug
gaps are as specified. To carry out the
adjustments, an accurate tachometer and an
exhaust gas analyser (CO meter) will be
required.
12Idle speed is controlled by the EEC IV
module, and manual adjustment is not possible,
although the “base” idle speed can be adjusted
by a Ford dealer using special equipment.
13On models with a catalytic converter, the
mixture is controlled by the EEC IV module,
and no manual adjustment is possible.
14On models without a catalytic converter,
the idle mixture can be adjusted as follows.
15Run the engine until it is at normal
operating temperature.
16Stop the engine and connect a tachometer
and an exhaust gas analyser in accordance
with the manufacturer’s instructions.
17Start the engine and run it at 3000 rpm
for 15 seconds, ensuring that all electrical
loads (headlamps, heater blower, etc) are
switched off, then allow the engine to idle, and
check the CO content. Note that the reading
will initially rise, then fall and finally stabilise.
18If adjustment is necessary, remove the
cover from the mixture adjustment
potentiometer (located on the right-hand side
of the engine compartment, behind the MAP
sensor), and turn the screw to give the
specified CO content (see illustration).
19If adjustment does not produce a change
in reading, the potentiometer may be at the
extreme of the adjustment range. To centralise
the potentiometer, turn the adjustment screw
20 turns clockwise followed by 10 turns anti-
clockwise, then repeat the adjustment
procedure.
