The cylinder head is of crossflow design
with the inlet manifold mounted on the left-
hand side and the exhaust manifold mounted
on the right-hand side.
Lubrication is by means of a bi-rotor pump
which draws oil through a strainer located
inside the sump, and forces it through a full-
flow filter into the engine oil galleries where it
is distributed to the crankshaft, camshaft and
auxiliary shaft. The big-end bearings are
supplied with oil via internal drillings in the
crankshaft.The undersides of the pistons are
supplied with oil from drillings in the big-ends.
The distributor shaft is intermittently supplied
with oil from the drilled auxiliary shaft. The
camshaft and cam followers are supplied with
oil via a drilled spray tube from the centre
camshaft bearing.
A semi-closed crankcase ventilation system
is employed whereby piston blow-by gases
are drawn into the inlet manifold via an oil
separator and on carburettor models a control
valve.
The following operations can be carried out
without removing the engine, although the
work may be easier and quicker with the
engine removed:
a)Removal and refitting of the cylinder head
b)Removal and refitting of the camshaft
(after removing the cylinder head)
c)Removal and refitting of the timing belt
and sprockets
d)Removal and refitting of the sump and oil
pump
e)Removal and refitting of the pistons,
connecting rods and big-end bearings
f)Renewal of the engine mountings
g)Renewal of the crankshaft oil seals
h)Removal and refitting of the auxiliary shaft
j)Removal and refitting of the flywheel
The engine must be removed from the
vehicle for the following operations:
a)Renewal of the crankshaft main bearings
b)Removal and refitting of the crankshaft
The engine may be lifted out either on its
own or together with the gearbox. Unless work
is also necessary on the gearbox it is
recommended that the engine is removed on
its own. Where automatic transmission is
fitted, the engine should be removed on its
own owing to the additional weight. If the
engine and gearbox are removed together,
they will have to be tilted at a very steep angle;
make sure that the range of the lifting tackle is
adequate.1Disconnect the battery negative lead.
2Remove the bonnet.
3On carburettor models, remove the air
cleaner. On fuel-injection models, remove the
air cleaner cover, vane airflow meter and air
inlet trunking.
4If a splash guard is fitted, remove it.
5Release the securing clips and bolts and
remove the upper half of the fan shroud. On
carburettor models remove the lower half of
the shroud too.
6Drain the cooling system.
7Disconnect the radiator top and bottom
hoses from the thermostat housing and water
pump. Disconnect the top hose spur from the
expansion tank and unclip it.
8Disconnect the heater hoses from the water
pump and from the inlet manifold or automatic
choke housing. Unclip the hoses.
9On models with power steering, remove the
steering pump.
10Disconnect the vacuum pipe(s) from the
inlet manifold, labelling them if there is any
possibility of confusion.
11Disconnect the following wiring, as
applicable:
a)Alternator

13If an oil level sensor is fitted, remove it
(see illustration).
14Unbolt the throttle cable bracket,
disconnect the inner cable and move the cable
and bracket aside. Also disconnect the
downshift cable on automatic transmission
models.
15On carburettor models, disconnect the
fuel lines from the fuel pump (mechanised
type) and from the carburettor. Be prepared
for fuel spillage.
16On fuel-injection models, disconnect the
fuel supply union from the injector rail, and the
fuel return pipe from the fuel pressureregulator. Be prepared for fuel spillage, and
for some spray if the supply side is still
under pressure.
17Unbolt the exhaust downpipe from the
manifold.
18On models with air conditioning, unbolt
the compressor and move it aside without
straining the flexible hoses.
19Remove the starter motor.
20Although not specified by the
manufacturers, the author advises that either
the radiator or the cooling fan be removed, to
reduce the risk of damage.
21Attach the lifting tackle to the two lifting
eyes on the engine, so that when suspended
the engine will be roughly horizontal. Take the
weight of the engine.
22Remove the single nut on each side which
secures each engine bearer to its mounting.
23Working under the vehicle, remove the
bracing strap which connects the engine and
transmission. Unbolt the adapter plate from
the bottom of the transmission bellhousing.
24On automatic transmission models, unbolt
the torque converter from the driveplate.
25Remove the engine-to-bellhousing bolts.
Note the location of the battery earth strap.
26Support the transmission, preferably with
a trolley jack.
27Check that nothing has been overlooked,
then raise the engine and draw it forwards
clear of the transmission input shaft. Do not
allow the weight of the engine to hang on the
shaft, and do not lift the transmission by it.
28On automatic transmission models, make
sure that the torque converter stays engaged
with the oil pump in the transmission as the
engine is withdrawn,
29Lift the engine out of the engine bay and
take it to the bench.
1Engine removal with automatic transmission
is not recommended.
2Proceed as in the previous Section,
paragraphs 1 to 18.

14Take the weight of the engine and remove
the two engine bearer-to-mounting nuts.
15Lift the engine/transmission, at the same
time lowering the trolley jack. Draw the unit
forwards and lift it out of the engine bay.
16Temporarily refit the anti-roll bar if the
vehicle is to be moved.
1With the engine and gearbox on the bench,
remove the starter motor.
2Remove the bolt from the engine adapter plate.
3Remove the bracing strap and the
remaining engine-to-bellhousing bolts.
4With the aid of an assistant draw the
gearbox off the engine. Do not allow the weight
of the gearbox to hang on the input shaft.
1It is best to mount the engine on a
dismantling stand, but if this is not available,
stand the engine on a strong bench at a
comfortable working height. Failing this, it will
have to be stripped down on the floor.
2Cleanliness is most important, and if the
engine is dirty, it should be cleaned with
paraffin while keeping it in an upright position.
3Avoid working with the engine on a concrete
floor, as grit can be a real source of trouble.
4As parts are removed, clean them in paraffin.
However, do not immerse parts with internal
oilways in paraffin as it is difficult to remove,
usually requiring a high pressure hose.
5It is advisable to have suitable containers to
hold small items according to their use, as this
will help when reassembling the engine and
also prevent possible losses.
6Always obtain complete sets of gaskets
when the engine is being dismantled, but
retain the old gaskets with a view of using
them as a pattern to make a replacement if a
new one is not available.7When possible, refit nuts, bolts and washers
in their location after being removed, as this
helps protect the threads and will also be
helpful when reassembling the engine.
8Retain unserviceable components in order
to compare them with the new parts supplied.
9A Torx key, size T55, will be needed for
dealing with the cylinder head bolts. A 12-
spline key (to fit bolt size M8) will be needed
for the oil pump bolts. Other Torx and 12-
spline bolts may be encountered; sets of the
keys required to deal with them are available
from most motor accessory shops and tool
factors.
10Another tool which is useful, though by no
means essential, is a valve spring compressor
of the type which hooks under the camshaft
(see illustration). As a Ford tool this bears the
number 21-005-A; proprietary versions may
also be available.
Before dismantling the engine into its main
components, the following ancillary
components can be removed. The actual
items removed, and the sequence of removal,
will depend on the work to be done:
Inlet manifold and associated items
Exhaust manifold
Fuel pump (mechanical type) and pushrod
Alternator
Distributor, HT leads and spark plugs
Fan, water pump and thermostat
Oil pressure switch
(see illustration)
Temperature gauge senderOil filter and dipstick
Engine bearer arms (see illustration)
Crankcase ventilation components
Clutch
Alternator mounting bracket (see
illustration)
1If the engine is still in the vehicle, carry out
the following preliminary operations:
a)Disconnect the battery negative lead
b)Drain the cooling system
c)Remove the inlet and exhaust manifolds
d)Disconnect the radiator top hose from the
thermostat housing, and the spur from the
expansion tank
e)Disconnect the wiring from the
temperature gauge sender
f)Remove the distributor cap, HT leads and
spark plugs
2Unscrew the bolts and withdraw the timing
cover (see illustration). Note the location of
the cover in the special bolt.
3Using a socket on the crankshaft pulley bolt.
turn the engine clockwise until the TDC (top
dead centre) notch on the pulley is aligned
with the pointer on the crankshaft front oil seal
housing, and the pointer on the camshaft
sprocket is aligned with the indentation on the
cylinder head (see illustrations).Note the
position of the distributor rotor arm, and mark
its contact end in relation to the rim of the
distributor body.

See Chapter 1, Section 23.
1Make a final check to ensure that everything
has been reconnected to the engine and that no
rags or tools have been left in the engine bay.
2Check that oil and coolant levels are
correct.
3Start the engine. This may take a little longer
than usual as fuel is pumped up to the engine.
4Check that the oil pressure light goes out
when the engine starts.
5Run the engine at a fast tickover and check
for leaks of oil, fuel and coolant. Also check
power steering and transmission fluid cooler
unions, when applicable. Some smoke and
odd smells may be experienced as assembly
lubricant burns off the exhaust manifold and
other components.6Bring the engine to operating temperature.
Check the ignition timing then adjust the idle
speed (if applicable) and mixture.
7Stop the engine and allow it to cool, then re-
check the oil and coolant levels.
8If new bearings, pistons etc have been
fitted, the engine should be run in at reduced
speeds and loads for the first 500 miles (800
km) or so. It is beneficial to change the engine
oil and filter after this mileage.
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 dismantlingthe 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

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.

The 2.0 litre DOHC (Double OverHead
Camshaft) engine was introduced in June
1989 to replace the 2.0 litre SOHC engine
used previously in the Granada range, at the
same time a 2.0 litre version of the Scorpio
model was also introduced. The engine is of
four-cylinder, in-line type.
The crankshaft incorporates five main
bearings. Thrustwashers are fitted to the
centre main bearing in order to control
crankshaft endfloat.
The camshafts are driven by a chain from
the crankshaft and operate the angled valves
via hydraulic cam followers. One camshaft
operates the inlet valves, and the other
operates the exhaust valves.
The distributor is driven directly from the
front of the inlet camshaft, and the oil pump is
driven by a chain from the crankshaft. An
electric fuel pump is mounted in the fuel tank.
Lubrication is by means of a bi-rotor pump
which draws oil through a strainer located
inside the sump, and forces it through a full-
flow filter into the engine oil galleries, from
where it is distributed to the crankshaft and
camshafts. The big-end bearings are supplied
with oil via internal drillings in the crankshaft.
The undersides of the pistons are suppliedwith oil from drillings in the connecting rods.
The hydraulic cam followers are supplied with
oil from passages in the cylinder head. The
camshafts are lubricated by oil from spray
tubes mounted above the camshaft bearing
caps.
A closed crankcase ventilation system is
employed, whereby piston blow-by gases are
drawn from the crankcase, through a breather
pipe into the inlet manifold where they are
burnt with fresh air/fuel mixture.The crankcase ventilation system (see
illustration)consists of an oil separator and
vent valve fitted to the cylinder block on the
left-hand side of the engine. This is connected
by a pipe to the inlet manifold. The system
operates according to the vacuum in the inlet

manifold. Piston blow-by gases are drawn
through the oil separator and the vent valve to
the inlet manifold. The blow-by gases are then
drawn into the engine together with the fuel/air
mixture. Refer to Chapter 1 for maintenance of
the system.
The following operations can be carried out
without removing the engine from the vehicle.
a)Removal of the camshafts.
b)Removal and servicing of the cylinder
head.

Note: A hoist and lifting tackle will be required
to lift the engine out of the vehicle.
1Disconnect the battery negative lead.
2Remove the bonnet.
3On carburettor models, remove the air cleaner.
4On fuel-injection models, remove the air
inlet hose, plenum chamber and air cleaner lid
as an assembly.
5Disconnect the breather hose from the
camshaft cover, and unscrew the bolt
securing the hose support bracket to the left-
hand side of the cylinder head (see
illustration).
6Drain the cooling system.
7To provide additional working space,
remove the radiator.8Disconnect the coolant hoses from the
water pump housing on the left-hand side of
the engine and the cylinder head (see
illustration).
9Disconnect the coolant hoses from the
thermostat housing.
10Disconnect the heater coolant hose from
the inlet manifold.
11Where applicable, release the coolant
hose from the bracket under the carburettor
automatic choke housing.
12Disconnect the throttle cable and (where
necessary) speed control cable from the
throttle linkage.
13On carburettor models, disconnect the
vacuum pipe from the engine management
module.
14Disconnect the brake servo vacuum hose
(where necessary) from the inlet manifold.
15On fuel-injection models, disconnect the
vacuum pipes from the MAP sensor (located
on the suspension turret on the right-hand
side of the engine compartment) and, where
applicable, the air conditioning system.
16On carburettor models, disconnect the
fuel supply and return hoses at the
carburettor, and plug the ends of the hoses to
minimise petrol spillage. Take adequate fire
precautions.
17On fuel-injection models, slowly loosen
the fuel feed union at the fuel rail to relieve the
pressure in the fuel system before
disconnecting the union. Be prepared for
petrol spillage and take adequate fire
precautions. Disconnect the fuel feed hose,and disconnect the fuel return hose from the
fuel pressure regulator. Plug the ends of the
hoses to minimise petrol spillage.
18Disconnect the HT lead from the ignition
coil, and unclip it from the timing chain cover.
19Disconnect the wiring from the following
components as applicable, depending on
model. Then free the wiring loom from any
necessary retaining clips or ties and position it
clear of the engine.
a)Alternator.
b)Starter motor.
c)Oil pressure warning lamp switch.
d)Temperature gauge sender.
e)Cooling fan switch.

m)Fuel injectors.
20Remove the water pump/alternator
drivebelt, then unbolt the power steering
pump from the mounting bracket and move it
clear of the engine. Note that there is no need
to disconnect the fluid hoses, but make sure
that the pump is adequately supported to
avoid straining them.
21On models fitted with air conditioning,
unbolt the air conditioning compressor from the
mounting bracket, and move it clear of the
engine (see illustration). Do notdisconnect the
hoses, but make sure that the compressor is
