1985 FORD GRANADA fuel pump

6Lubricate the pushrods with engine oil and
insert them in the cylinder block.
7Place the oil splash shields in position on
the cylinder heads and fit the rocker shaft
assemblies. Guide the rocker arm adjusting
screws into the pushrod sockets (see
illustrations).
8Tighten the rocker shaft securing bolts
progressively to the specified torque.
9Refit the inlet manifold, using a new gasket.
Do not refit the rocker covers yet.
10Adjust the valve clearances (Section 39).
11Refit the spark plugs.
12Refit the rocker covers, using new
gaskets. The adhesive side of the gaskets
should face the rocker cover.
13If the engine is in the vehicle, reverse the
preliminary steps.2.4 & 2.9 litre engines
14Refitting the cylinder heads to these
engines is essentially a reversal of the removal
procedure but also refer to information given
for the 2.8 litre engine whilstnoting the
following points.
15Always use new Torx type cylinder head
bolts. Oil them and allow them to drain. When
fitted the word OBEN should be visible on the
new gaskets.
16Tighten the bolts in the specified
sequence (as for the 2.8 litre engine) to the
correct torque. The final stage in the tightening
procedure is by the angular method. Use a
disc similar to the one shown or make a paint
mark at the same point on each bolt head to
ensure that each bolt is turned through exactly
the same number of degrees (see
illustration).17As a result of the bolt tightening torque
used and the elasticity of the bolts, no further
tightening is required after the initial running-in
period.
18Apply jointing compound to the areas
where the inlet manifold and cylinder heads
meet and locate a new gasket in position.
Make sure that it is the correct way around.
Tighten the inlet manifold bolts to the specified
torque and in the sequence shown (see
illustrations).
19Check that No 1 piston is still at the firing
point (12°BTDC) and fit the distributor.
20Adjust the valve clearances.
21Fit new rocker cover gaskets, peeling off
the self-adhesive shield before sticking the
gaskets to the covers. Note the aluminium
spacers in the gaskets to prevent
overtightening (see illustration).
22Use a new gasket at the plenum chamber
and tighten the fixing bolts to the specified
torque (see illustration).
23Refit the alternator and power steering
pump (where removed) and tension the
drivebelts.
24Reconnect the fuel lines and secure them
in position with new clips. Reconnect all
coolant and vacuum hoses and electrical
connectors. Refill the engine with coolant and
reconnect the battery.
25Switch on the ignition and bleed the fuel
system by operating the vent valve on the fuel rail.
26Run the engine up to normal operating
temperature and then check the ignition
timing.

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.

11Refill the cooling system.
DOHC engines
12Disconnect the battery negative lead.
13On fuel-injection models, for access to the
water pump, remove the air inlet hose, plenum
chamber, and air cleaner lid as an assembly.
14Drain the cooling system.
15Remove the water pump/alternator
drivebelt.16If the pump pulley is to be removed, it is
easiest to do this with the pump in position as
follows. Prevent the pulley from rotating using
a strap wrench (which can be improvised
using an old drivebelt and a large socket and
wrench), and unscrew the four pulley securing
bolts. Withdraw the pulley.
17Position a suitable container beneath the
water pump to catch the coolant which will be
released as the pump is removed, then
unscrew the five securing bolts and withdraw
the pump from the housing in the cylinder
block (see illustration). Recover the O-ring
seal and discard it; a new one must be used
on refitting.
18Refitting is a reversal of removal, bearing
in mind the following points:
a)Ensure that the mating faces of the water
pump and cylinder block are clean and fit
a new O-ring to the pump (see
illustration).
b)Tighten the water pump bolts and where
applicable the pump pulley bolts to the
specified torque.
c)On completion refill the cooling system.
19Note that on models up to May 1990, the
coolant hoses were connected to the water
pump housing as shown(see illustration).
20On models from May 1990, the heater
hose (A) and the expansion tank hose (B)
connections were swapped over.21If the hoses are disconnected on earlier
models, such as during engine removal, they
should be reconnected as on later models, ie
connect the heater hose to connection B and
connect the expansion tank hose to connection
A. This will reduce the possibility of noises from
the heater matrix due to air in the system.

28Remove the twelve securing bolts and
withdraw the water pump. Note that on some
models it will be necessary to remove the
crankshaft pulley and damper to gain access
to the lower water pump bolts (see
illustration).
29A leaking, noisy or otherwise defective
pump must be renewed.
30Clean the mating faces and obtain a new
gasket for reassembly. Use a new thermostat
housing gasket also.
31Refit by reversing the removal operation,

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.
1General information and
precautions
procarmanuals.com

4With the engine cold, disconnect the cold
air inlet trunking from the spout. Look into the
spout and check that the flap valve is covering
the hot air inlet.
5Start the engine and allow it to idle. Check
that the flap moves to cover the cold air inlet. If
the flap does not move, check the diaphragm
and heat sensor as follows.
6Stop the engine. Disconnect the diaphragm
vacuum pipe from the heat sensor. Apply
vacuum to the diaphragm, using a vacuum
head pump or by connecting the pipe directly
to manifold vacuum. If the flap now moves, the
heat sensor or vacuum line was faulty. If the
flap still does not move, the diaphragm is
faulty or the flap is jammed.
7On completion reconnect the vacuum pipe
and the cold air trunking.
Mechanical
1Carburettor models without air conditioning
are fitted with a mechanical fuel pump, located
on the left-hand side of the engine block.
2To test the pump, disconnect the ignition
coil LT lead. Disconnect the outlet hose from
the pump and place a wad of rag next to the
pump outlet. Take appropriate fire
precautions.
3Have an assistant crank the engine on the
starter. Well-defined spurts of fuel must beejected from the pump outlet - if not, the pump
is probably faulty (or the tank is empty).
Dispose of the fuel-soaked rag safely.
4To remove the fuel pump, first disconnect
the battery negative lead.
5Disconnect and plug the pump inlet and
outlet hoses. Be prepared for fuel spillage.
6Unscrew the two bolts and withdraw the
pump from the cylinder block. Remove the
gasket. If necessary extract the pushrod (see
illustrations).
7Clean the exterior of the pump in paraffin
and wipe dry. Clean all traces of gasket from
the cylinder block and pump flange.
8If the fuel pump has a removable cover,
remove the screw and withdraw the cover and
nylon mesh filter with seal (see illustrations).
Clean the filter, cover and pump in fuel. Locate
the filter in the cover and fit the cover to the
pump so that the pipe and indentation are
aligned. Tighten the screw.
9Refitting is a reversal of removal, but fit a
new gasket and tighten the bolts to the
specified torque. If necessary discard the
crimped type hose clips and fit screw type
clips.
Electrical
SOHC and 2.8 litre V6 engines
10All fuel-injection models, and carburettor
models when fitted with air conditioning, have
an electric fuel pump. The two types of pump
are not the same, although both are mounted
under the vehicle next to the fuel tank.11If the fuel pump appears to have failed
completely, check the appropriate fuse and
relay. On fuel-injection models, also check the
inertia switch (when fitted).
12To test the carburettor type pump,
disconnect the fuel supply hose from the
pressure regulator or vapour separator in the
engine compartment. Lead the hose into a
measuring cylinder.
13Take appropriate fire precautions. Switch
on the ignition for 30 seconds and measure
the quantity of fuel delivered: it should be at
least 400 cc (0.7 pint).
14To test the fuel-injection type pump,
special equipment is required. Consult a Ford
dealer or other fuel-injection specialist. The
problem may be due to a clogged filter.
15To remove a pump, first disconnect the
battery negative lead. Take appropriate fire
precautions.
16Raise and support the rear of the vehicle.
Clean the fuel pump and its surroundings.
17Clamp the tank-to-pump hose, or make
arrangements to collect the contents of the
fuel tank which will otherwise be released.
18Place a drain pan beneath the pump.
Disconnect the inlet and outlet hoses; be
prepared for fuel spillage. Caution: Fuel under
pressure may spray out of the outlet hose
union as it is slackened.
19Disconnect the wiring plug from the pump.
20Slacken the pump bracket clamp bolt and
slide the pump out of the bracket.
21Refit by reversing the removal operations.
Make sure that all hoses and unions are in
good condition.
22On2.4 & 2.9 litre V6 engines up to mid-
1990, switch the ignition on and off five times,
without cranking the engine, to pressurise the
fuel system then check the pump unions for
signs of leakage.
23Run the engine and check for leaks.
DOHC engine
24On these models the fuel pump is
mounted in the fuel tank, on the same
mounting as the fuel level sender unit(see
illustration).To test the pump specialist
equipment is required, therefore this task must
be entrusted to a Ford dealer.

25To remove the pump, first remove the fuel
tank.
26Unscrew the fuel pump/fuel level sender
unit by engaging two crossed screwdrivers in
the slots on either side of the unit mounting
flange. Recover the seal.
27Refitting is a reversal of removal. It is
necessary to fit a new seal.
1Run the fuel level as low as possible before
removing the tank.
2Disconnect the battery negative lead.
3Remove the fuel filler cap. Siphon or pump
the remaining fuel out of the tank. Store the
fuel in a suitable sealed container.
4Remove the two screws on either side of the
filler neck.
5Raise and support the rear of the vehicle.
6Remove the shield from the right-hand rear
inner wheel arch. Also remove the rear bumper
undershield. which is secured by six screws.
7Disconnect the fuel supply and return lines
from the tank (see illustration). Drain the fuel
in the lines into a suitable container and
remove it.
8Support the fuel tank. Remove the two bolts
which secure the rear ends of the fuel tank
supporting straps.
9Lower the tank and supporting straps,unhooking the front ends of the straps from
their locations. Disconnect the wiring and the
vent hose from the tank. Remove the tank with
filler pipe attached.
10Fuel tank repairs including soldering or
welding must be left to specialists. Even when
empty, the tank may contain explosive vapour.
Proprietary compounds are available for
making temporary “cold” repairs.
11Refit the fuel tank in the reverse order to
removal. Check for leaks on completion.
1Remove the fuel tank.
2Unscrew the sender unit from the tank.
There is a Ford tool (No 23-014) which
engages with the lugs on the unit, but with
patience a pair of crossed screwdrivers or
similar items can be used instead.
3Remove the sender unit, taking care not to
damage the float or bend the float arm(see
illustration).Recover the seal.
4A defective sender unit must be renewed;
spares are not available. Renew the seal in any
case.
5Refit by reversing the removal operations.
1Fitted to DOHC and 2.4 & 2.9 litre V6
engined models, this device is designed to cutoff pressurised fuel to the fuel-injection system
in the event of an accident. It does this by
interrupting the electrical supply to the fuel
pump.
2To remove the switch, first disconnect the
battery negative lead.
3Open up the tailgate and locate the switch
which is mounted near the tailgate lock striker.
On Estate models the switch is located behind
a trim panel in the rear right-hand corner of the
luggage compartment (see illustration).
4Remove the trim panel and disconnect the
switch wiring connector (see illustrations).
5Extract the two retaining screws and
remove the switch.
6Refitting is a reverse of the removal
procedure. On completion, depress the switch
button to ensure that the switch has been
reset.
1Disconnect the battery negative lead.
2Unclip the under-dash insulation on the
driver’s side.
3Disconnect the cable from the pedal. The
cable may be secured by a clip, or it may slot
into a “keyhole” fitting (see illustration).
