1985 FORD GRANADA warning light

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.

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.

Models covered in this Manual have disc
brakes fitted all round. The footbrake operates
hydraulically on all four wheels, and the
handbrake operates mechanically on the rear
wheels. Both footbrake and handbrake are
self-adjusting in use.
Ford’s anti-lock braking system (ABS) is
fitted to all models. The system monitors the
rotational speed of each roadwheel. When a
wheel begins to lock under heavy braking, the
ABS reduces the hydraulic pressure to that
wheel, so preventing it from locking. When this
happens a pulsating effect will be noticed at
the brake pedal. On some road surfaces the
tyres may squeal when braking hard even
though the wheels are not locked.
The main components of the system are the
hydraulic unit, the calipers, pads and discs,
the wheel sensors and the “brain” or control
module. The hydraulic unit contains the
elements of a traditional master cylinder, plus
an electric motor and pump, a pressure
accumulator and control valves. The pump is
the source of pressure for the system and
does away with the need for a vacuum servo.
The hydraulic circuit is split front and rear,
as is normal practice with rear-wheel drive
vehicles. In the event that the hydraulic pump
fails, unassisted braking effort is still available
on the front calipers only.
Warning lights inform the driver of low brake
fluid level, ABS failure and (on some models)
brake pad wear. The low fluid level light
doubles as a “handbrake on” light; if it
illuminates at the same time as the ABS
warning light, it warns of low hydraulic
pressure.
ABS cannot overturn the laws of physics:
stopping distances will inevitably be greater on
loose or slippery surfaces. However, the system
should allow even inexperienced drivers to
retain directional control under panic braking.
From August 1986 the following
modifications were made to the braking
system.
a)The relays differ from earlier versions.b)The hydraulic pump is constructed of iron
rather than alloy.
c)A new pressure warning switch is used.
d)The earlier high pressure rubber hose is
replaced by a steel pipe.
To overcome the problem of excessive rear
brake pad wear, Ford introduced a differential
valve which is screwed into the ABS valve
block.The valve limits the pressure applied to
the rear brake calipers and so reduces brake
pad wear. From 1988 onwards, the valve has
been fitted during production. The differential
valve can also be fitted to earlier models. Refer
to your Ford dealer for further information.
From April 1992 onwards, the models
covered in this Manual were equipped with a
new Teves MK IV anti-lock braking system
instead of the Teves MK II system fitted to the
earlier models.
The Teves MK IV system differs from the
earlier MK II system in the following ways.
a)The source of hydraulic pressure for the
system is a conventional master cylinder
and vacuum servo assembly.
b)A valve block and pump assembly is used
instead of the hydraulic control unit. The
block contains the inlet and outlet
solenoid valves that control the hydraulic
system. There are three pairs of valves,
one for each brake circuit (paragraph c).
c)The hydraulic braking system consists of
three separate circuits; one for each front
brake (which are totally independent of
each other), and a joint circuit which
operates both rear brakes.
d)A G (gravity) switch is incorporated in the
system. This is an inertia type switch and
informs the control module when the
vehicle is decelerating rapidly.
e)A Pedal Travel Sensor (PTS) is fitted to the
vacuum servo unit. The PTS informs the
control module of the position of the brake
pedal when the anti-lock sequence starts
and ensures that a constant pedal height
is maintained during the sequence.
The MK IV system operates as follows.
During normal operation the system
functions in the same way as a non-ABS
system would. During this time the three inlet
valves in the valve block are open and theoutlet valves are closed, allowing full hydraulic
pressure present in the master cylinder to act
on the main braking circuit. If the control
module receives a signal from one of the
wheel sensors and senses that a wheel is
about to lock, it closes the relevant inlet valve
in the valve block which then isolates the
brake caliper on the wheel which is about to
lock from the master cylinder, effectively
sealing in the hydraulic pressure. If the speed
of rotation of the wheel continues to decrease
at an abnormal rate, the control module will
then open the relevant outlet valve in the valve
block; this allows the fluid from the relevant
hydraulic circuit to return to the master
cylinder reservoir, releasing pressure on the
brake caliper so that the brake is released. The
pump in the valve block also operates to assist
in the quick release of pressure. Once the
speed of rotation of the wheel returns to an
acceptable rate the pump stops, the outlet
valve closes and the inlet valve is opened,
allowing the hydraulic master cylinder
pressure to return to the caliper which then
reapplies the brake. This cycle can be carried
many times a second. The solenoid valves
connected to the front calipers operate
independently, but the valve connected to the
rear calipers operates both calipers
simultaneously.
The operation of the ABS system is entirely
dependent on electrical signals. To prevent
the system responding to any inaccurate
signals, a built-in safety circuit monitors all
signals received by the control module. If an
inaccurate signal or low battery voltage is
detected, the ABS system is automatically
shut down and the warning lamp on the
instrument cluster is illuminated to inform the
driver that the ABS system is not operational.
Whilst in this state the system functions in the
same way as a non-ABS system would. If a
fault does develop in the ABS system, the car
must be taken to a Ford dealer for fault
diagnosis and repair. The system is equipped
with a diagnostic plug into which a special
diagnostic (STAR) tester can be plugged. This
allows faults to be easily traced.

5Extract the piston seal from the groove in
the bore, using a blunt instrument (see
illustration). Discard the seal and dust boot.
6Clean the piston and bore with methylated
spirit and inspect them for scuffs, scores or
other damage. If the piston is corroded it must
be renewed. Slight imperfections in the bore
can be polished out with wire wool.
7Place the clean component on a clean
surface ready for reassembly. Lubricate the
caliper hose with clean hydraulic fluid.
8Fit the new piston seal to the groove in the
bore, using fingers only to work it into position.
9Lubricate the piston with clean hydraulic
fluid and fit the dust boot over the piston,
making sure it is the right way up. Insert the
piston into the bore and press it home,
engaging the dust boot lip with the groove on
the caliper (see illustration).
10This completes the overhaul of the hydraulic
components. Items such as slide bolts and
bracket can also be renewed if necessary.
11Remove the bleed screw while the caliper
is on the bench and apply a little anti-seize
compound to its threads, to avoid trouble in
undoing it later.
1With the ignition off, pump the brake pedal
at least 20 times (or until it becomes hard) to
depressurise the system.
2Chock the front wheels and release the
handbrake. Slacken the rear wheel nuts, raiseand support the vehicle and remove the
relevant wheel.
3Disconnect the pad wear warning wires,
when fitted.
4Disconnect the flexible hose from the brake
pipe. Plug or cap the open unions to reduce
spillage and to keep dirt out. Unscrew the
flexible hose from the caliper and remove it.
5Remove the two slide bolts. Lift the caliper
off the pads and bracket, at the same time
unhooking the handbrake cable (see
illustrations). Alternatively, the two bracket-
to-hub bolts can be removed and the caliper
and bracket separated on the bench.
6Refit by reversing the removal operations,
but before refitting the wheel, bleed both rear
calipers as described in Section 2.
7When bleeding is complete, pump the brake
pedal several times to bring the pads up to the
disc, then check the operation of the
handbrake.
Note: Complete dismantling of the rear caliper
should not be attempted unless Ford spring
compressor (tool No 12-007) is available. or
unless the problems likely to arise in the absence
of the tool are understood. Renewal of the piston
seal and dust boot requires no special tools.
1Clean the caliper externally and mount it in a
soft-jawed vice.
2Rotate the piston anti-clockwise until it isprotruding from the bore by about 20 mm (0.8 in).
Free the dust boot from the groove in the
piston, then carry on unscrewing the piston
and remove it. Remove and discard the dust
boot.
3The piston and bore may now be cleaned
and examined, and the piston seal and dust
boot renewed, as described for the front
caliper (Section 10).
4The piston adjuster nut seal should also be
renewed. Remove the circlip from the piston,
then extract the thrustwashers, wave washer
and thrust bearing. Note the fitted sequence of
these components. Finally remove the nut
(see illustrations).
5Remove the seal from the nut, noting which
way round it is fitted. Clean the nut with
methylated spirit. Lubricate the new seal with
clean hydraulic fluid and fit it to the nut.
