1985 FORD GRANADA transmission

13Apply a sealing compound to the faces of
the cylinder block and sump at the points
indicated(see illustration).
14Apply suitable thread-locking compound
to the sump securing studs and bolts, then
locate the sump on the cylinder block and fit
the securing nuts and bolts, but do not fully
tighten them at this stage.
15Align the sump so that the end faces and
the cylinder block are flush. To do this, use a
straight-edge. If the sump cannot be
positioned so that the faces of the cylinder
block and sump are flush, measure the
difference in height using a feeler blade as
shown (see illustration).
16Tighten the sump securing nuts and bolts
to the specified torque, then repeat the
measurement made in paragraph 15. If the
end faces of the sump and cylinder block are
not flush, suitable shims must be fitted
(available from a Ford dealer) between the
sump and the gearbox/transmission to
eliminate the clearance when mating the
engine to the gearbox/transmission. Note that
shims should be fitted at both sides of the
sump, as required. Select suitable shims from
those listed in the following table.
Clearance measuredShims required
0 to 0.25 mmNo shims required
0.25 to 0.29 mm0.15 mm (silver)
0.30 to 0.44 mm0.30 mm (light blue)
0.45 to 0.59 mm0.45 mm (red)
0.60 to 0.75 mm0.60 mm (black)
17If the engine is in the vehicle, reverse the
procedure described in paragraphs 3 to 8,
noting the following points.
a)Ensure that the roadwheels and the
steering wheel are in the straight-aheadposition then align the marks made on
removal and reconnect the intermediate
shaft to the steering gear. Tighten the
clamp bolt to the specified torque.
b)Fill the engine with the correct grade and
quantity of oil.
c)Refit the engine adapter plate and the
flywheel/driveplate.
d)Refit the gearbox or automatic
transmission, as applicable, ensuring that
the required shims are fitted between the
sump and the gearbox/transmission.
e)Tighten all fixings to the specified torque
where applicable.
Note: A suitable puller will be required to
remove the crankshaft pulley. A new
crankshaft pulley bolt, a new lower timing
chain cover gasket and a new oil pump gasket
must be used on refitting.
1If the engine is in the car, carry out the
following operations.
a)Disconnect the battery negative lead.
b)To Improve access, remove the radiator. It
will be difficult to remove the crankshaft
pulley with the radiator in place.
c)On fuel-injection models, remove the air
inlet hose, plenum chamber and air
cleaner lid as an assembly.
2Proceed as described in paragraphs 3 to 10
of Section 15.3Unscrew the four securing bolts and
withdraw the oil pump from the cylinder block
(see illustration). Recover the gasket and
discard it.
4If desired, the pump can now be dismantled
and inspected.
5Thoroughly clean the mating faces of the
pump and the cylinder block.
6Prime the pump by injecting clean engine oil
into it and turning it by hand.
7Place a new gasket on the oil pump flange,
ensuring that the gasket is correctly located so
that the holes align with the oil passages in the
pump.
8Fit the oil pump, and tighten the securing
bolts to the specified torque.

The V6 engine fitted to the Granada is only
available in fuel-injected form. Mechanically,
the design of the engine is well-established,
and it is improved by the latest fuel, ignition and
engine management systems (see illustration).
The combined crankcase and cylinder block
is made of cast iron, and houses the pistons,
crankshaft and camshaft. The sump is
attached to the bottom of the crankcase and
the cylinder heads to the top.
The cylinder heads are of the crossflow
design, the inlet manifold being located
between them and the exhaust manifolds
being on the outboard sides. The overhead
valves are operated by tappets, pushrods and
rockers from the centrally located camshaft.
Camshaft drive is by gears (2.8 litre) or chain
(2.4 & 2.9 litre).
The crankshaft runs in four main bearings.
Endfloat is controlled by thrust flanges on the
No 3 bearing shells. The connecting rods are
selected so that all are in the same weight class.
Aluminium alloy pistons are used. The
gudgeon pins are an interference fit in their
connecting rods.The lubrication system is of the usual wet
sump, pressure fed type, with a full-flow
disposable canister oil filter. The oil pump is
driven by a shaft which engages in the bottom
of the distributor drivegear.
The following operations can be carried out
without removing the engine, although some
work will be easier and quicker with the engine
removed.
a)Removal and refitting of the cylinder
heads
b)Removal and refitting of the sump and oil
pump
c)Removal and refitting of the timing gears
d)Removal and refitting of the pistons,
connecting rods and big-end bearings
e)Renewal of the engine mountings
f)Removal and refitting of the flywheel
g)Renewal of the crankshaft front and rear
oil seals
h)Removal and refitting of the camshaft
(after removal of the cylinder heads,
tappets and timing gears)The engine must be removed for the
following operations:
a)Renewal of the crankshaft main bearings
b)Removal and refitting of the crankshaft
The engine is removed from above, without
the transmission. Removal with the
transmission is not recommended because of
the weight and unwieldiness of the combined
units.

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.

All models are fitted with a rear-mounted fuel
tank. Fuel is conveyed from the tank by a
mechanical or electrical fuel pump, according tomodel and equipment, to the carburettor or fuel-
injection system. The delivery capacity of the
fuel pump exceeds the maximum demands of
the system, so excess fuel is constantly returned
to the tank. This helps to avoid the problems of
vapour locks in the fuel lines.
Carburettor models have a twin venturidowndraught carburettor of Pierburg
manufacture on 1.8 litre models and Weber on
2.0 litre models. Both makes of carburettor
have an automatic choke.
Fuel-injection, when fitted, is of the Bosch
L-Jetronic type. This system is under the
control of the EEC IV module.
