When jump-starting a car using a
booster battery, observe the following
precautions:
A)Before connecting the booster
battery, make sure that the ignition is
switched off.
B)Ensure that all electrical equipment
(lights, heater, wipers, etc) is
switched off.C)Make sure that the booster battery is
the same voltage as the discharged
one in the vehicle.
D)If the battery is being jump-started
from the battery in another vehicle,
the two vehcles MUST NOT TOUCH
each other.
E)Make sure that the transmission is in
neutral (or PARK, in the case of
automatic transmission).
Jump starting will get you out
of trouble, but you must correct
whatever made the battery go
flat in the first place. There are
three possibilities:
1The battery has been drained by
repeated attempts to start, or by
leaving the lights on.
2The charging system is not working
properly (alternator drivebelt slack
or broken, alternator wiring fault or
alternator itself faulty).
3The battery itself is at fault
(electrolyte low, or battery worn out).
Connect one end of the red jump lead to
the positive (+) terminal of the flat
batteryConnect the other end of the red lead to
the positive (+) terminal of the booster
battery.Connect one end of the black jump lead
to the negative (-) terminal of the
booster battery
Connect the other end of the black
jump lead to a bolt or bracket on the
engine block, well away from the
battery, on the vehicle to be started.

Make sure that the jump leads will not
come into contact with the fan, drive-
belts or other moving parts of the
engine.5
Start the engine using the booster
battery, then with the engine running at
idle speed, disconnect the jump leads in
the reverse order of connection.6

16Unscrew the bolts and nuts securing the
manifold to the cylinder head and withdraw it
(see illustration). Take care not to damage
vulnerable components such as the EGR pipe
and valve as the manifold assembly is
manoeuvred out of the engine compartment.
Refitting
17Refitting is the reverse of the removal
procedure, noting the following points:
(a) When using a scraper and solvent to
remove all traces of old gasket material
and sealant from the manifold and
cylinder head, be careful to ensure that
you do not scratch or damage the
material of either; the cylinder head is of
aluminium alloy, while the manifold is a
plastics moulding - any solvents used
must be suitable for this application. If the
gasket was leaking, have the mating
surfaces checked for warpage at an
automotive machine shop. While it may
be possible to have the cylinder head
gasket surface skimmed if necessary, to
remove any distortion, the manifold must
be renewed if it is found to be warped,
cracked - check with special care around
the mounting points for components such
as the idle speed control valve and EGR
pipe - or otherwise faulty.
(b) Provided the relevant mating surfaces are
clean and flat, a new gasket will besufficient to ensure the joint is gas-tight.
Do notuse any kind of silicone-based
sealant on any part of the fuel system or
inlet manifold.
(c) Fit a new gasket, then locate the manifold
on the head and install the nuts and bolts
(see illustration).
(d) Tighten the nuts/bolts in three or four
equal steps to the torque listed in this
Chapter’s Specifications. Work from the
centre outwards, to avoid warping the
manifold.
(e) Refit the remaining parts in the reverse
order of removal - tighten all fasteners to
the torque wrench settings specified.
(f) When reassembling the
engine/transmission right-hand mounting,
renew the self-locking nuts, and do not
allow the mounting to twist as the middle
two of the bracket’s six nuts are
tightened.
(g) Before starting the engine, check the
accelerator cable for correct adjustment
and the throttle linkage for smooth
operation.
(h) When the engine is fully warmed up,
check for signs of fuel, intake and/or
vacuum leaks (see illustration).
(i) Road test the vehicle, and check for
proper operation of all disturbed
components.Warning: The engine must be
completely cool before beginning
this procedure.
Note:In addition to the new gasket and any
other parts, tools or facilities needed to carry
out this operation, a new plastic guide sleeve
will be required on reassembly.
Removal
1Disconnect the battery negative (earth) lead
- see Chapter 5, Section 1.
2Unbolt the resonator support bracket from
the engine compartment front crossmember,
slacken the two clamp screws securing the
resonator to the air mass meter and plenum
chamber hoses, then swing the resonator up
clear of the thermostat housing (see Chapter 4).
3Drain the cooling system (see Chapter 1).
4Disconnect the coolant hose and the
coolant pipe/hose from the thermostat
housing; secure them clear of the working
area.
5Unbolt the exhaust manifold heat shield,
and withdraw both parts of the shield (see
illustration). Apply penetrating oil to the EGR
pipe sleeve nut, and to the exhaust manifold
mounting nuts (also to the pulse-air system
sleeve nuts, if they are to be unscrewed).
6Unscrew the sleeve nut securing the EGR
pipe to the manifold, remove the two screws
securing the pipe to the ignition coil bracket,
then slacken the sleeve nut securing the pipe
to the EGR valve - see Chapter 6 for full
details if required.
7While the manifold can be removed with
the pulse-air system components attached -
unbolt the filter housing and disconnect its
vacuum hose if this is to be done - it is easier
to remove the pulse-air assembly first, as
described in Chapter 6 (see illustration).
8Unplugging the oxygen sensor electrical
connector to avoid straining its wiring,
unscrew the nuts to disconnect the exhaust
system front downpipe from the manifold (see
Chapter 4).

23If using Ford’s recommended procedure,
fit new oil seals to the camshafts as
described in paragraph 5 of Section 12.
24Using the marks and notes made on
dismantling to ensure that each is refitted to
its original camshaft, refit the toothed pulleys
to the camshafts, tightening the retaining
bolts loosely (see illustration). Slip the timing
belt back onto the pulleys (refer to para-
graph 21 of Section 10) and tighten the bolts
securely - use the forked holding tool
described in paragraph 18 of Section 10.
25The remainder of the reassembly
procedure, including checking the camshaft
alignment (valve timing) and setting the timing
belt tension, is as described in paragraphs 17
to 27 of Section 10.
Removal
Note:The following text assumes that the
cylinder head will be removed with both inlet
and exhaust manifolds attached; this
simplifies the procedure, but makes it a bulky
and heavy assembly to handle - an engine
hoist will be required, to prevent the risk of
injury, and to prevent damage to any delicate
components as the assembly is removed and
refitted. If it is wished first to remove the
manifolds, proceed as described in Sections
6 and 7 of this Chapter; amend the following
procedure accordingly.1Relieve the fuel system pressure (see
Chapter 4).
2With the vehicle parked on firm level
ground, open the bonnet and disconnect the
battery negative (earth) lead - see Chapter 5,
Section 1.
3Whenever you disconnect any vacuum
lines, coolant and emissions hoses, wiring
loom connectors, earth straps and fuel lines
as part of the following procedure, always
label them clearly, so that they can be
correctly reassembled.
4Unplugging the two electrical connectors,
disconnecting the vacuum hose (where fitted)
and disconnecting the crankcase breather
hose from the cylinder head cover, remove
the complete air cleaner assembly with the air
mass meter, the resonator and the plenum
chamber (see Chapter 4).
5Equalise the pressure in the fuel tank by
removing the filler cap, then undo the fuel
feed and return lines connecting the engine to
the chassis (see Chapter 4). Plug or cap all
open fittings.
6Disconnect the accelerator cable from the
throttle linkage as described in Chapter 4 -where fitted, disconnect also the cruise control
actuator cable (see Chapter 12). Secure the
cable(s) clear of the engine/transmission.
7Unbolt the power steering high-pressure
pipe from the cylinder head rear support
plate/engine lifting eye, and from the front
support plate/pump bracket. Releasing its
wire clip, unplug the power steering pressure
switch electrical connector, then unbolt the
earth lead from the cylinder head rear support
plate/engine lifting eye.
8Remove the three screws securing the
wiring “rail” to the rear of the manifold.
Releasing its wire clip, unplug the large
electrical connector (next to the fuel pressure
regulator) to disconnect the engine wiring from
the main loom (see illustration). Unplug the
electrical connectors on each side of the
ignition coil, and the single connector from
beneath the front of the thermostat housing, to
disconnect the coil and coolant temperature
gauge sender wiring (see illustration).
9Marking or labelling them as they are
unplugged, disconnect the vacuum hoses as
follows:
(a) One from the rear of the throttle housing
(only the one hose - there is no need to
disconnect the second hose running to
the fuel pressure regulator).
(b) One from the union on the inlet manifold’s
left-hand end (see illustration).
(c) The braking system vacuum servo unit
hose (see Chapter 9 for details).
(d) Disconnect all vacuum hoses from the
Exhaust Gas Recirculation system
components - one from the EGR valve
and two from the EGR pipe. (Note that
these last two are of different sizes, as are
their pipe stubs, so that they can only be
connected the correct way round.)
10Unbolt both parts of the exhaust manifold
heat shield; unclip the coolant hose to allow the
upper part to be withdrawn. Either remove the
dipstick and tube, or swing them out of the way.
11Unscrew the single bolt securing the
pulse-air filter housing to the engine/
transmission front mounting bracket, then
disconnect its vacuum hose.
12Drain the cooling system (see Chapter 1).
13Disconnect all coolant hoses from the
thermostat housing (see illustration).

then an ordinary socket extension bar and an
angle gauge, to tighten the cylinder head
bolts in the stages given in the Specifications
Section of this Chapter (see illustrations).
Note:Once tightened correctly, following this
procedure, the cylinder head bolts do not
require check-tightening, and must notbe re-
torqued.
33Refit the hydraulic tappets (if removed),
the camshafts, their oil seals and pulleys (see
Sections 10, 11, 12 and 13, as appropriate).
Temporarily refit the crankshaft pulley, and
rotate the crankshaft clockwise to return the
pulley notches to the position described in
paragraph 8 of Section 10.
34Refit the timing belt and covers, checking
the camshaft alignment (valve timing) and
setting the timing belt tension, as described in
Section 10.
35The remainder of reassembly is the
reverse of the removal procedure, noting the
following points:
(a) Tighten all fasteners to the torque wrench
settings specified.
(b) When reassembling the
engine/transmission right-hand mounting,
renew the self-locking nuts, and do not
allow the mounting to twist as the middle
two of the bracket’s six nuts are
tightened.
(c) Refill the cooling system, and top-up the
engine oil.
(d) Check all disturbed joints for signs of oil
or coolant leakage, once the engine has
been restarted and warmed-up to normal
operating temperature.
Removal
Note:To carry out this task with the
engine/transmission installed in the vehicle
requires the assistance of at least one person,
plus the equipment necessary to raise and
support the front of the vehicle (high enough
that the sump can be withdrawn from
underneath), and to lift and support the
complete engine/transmission unit 2 to 3 inches from its mountings while the vehicle
is raised. Precise details of the procedure will
depend on the equipment available - the
following is typical.
The full procedure outlined below must be
followed, so that the mating surfaces can be
cleaned and prepared to achieve an oil-tight
joint on reassembly, and so that the sump
can be aligned correctly; depending on your
skill and experience, and the tools and
facilities available, it may be that this task can
be carried out only with the engine removed
from the vehicle.
Note that the sump gasket must be
renewed whenever it is disturbed.
1With the vehicle parked on firm level
ground, open the bonnet and disconnect the
battery negative (earth) lead - see Chapter 5,
Section 1.
2Drain the engine oil, then clean and refit the
engine oil drain plug, tightening it to the
specified torque wrench setting. Although not
strictly necessary as part of the dismantling
procedure, owners are advised to remove
and discard the oil filter, so that it can be
renewed with the oil (see Chapter 1).
3Drain the cooling system (see Chapter 1).
4Disconnect the radiator bottom hose from
the radiator union and from the (heater)
coolant pipe. Unbolt the coolant pipe from
the sump; if they will prevent sump removal,
disconnect or release the coolant hoses from
the oil cooler unions (where fitted).
5Unscrew the two bolts securing the powersteering system pipes to the right-hand side
of the subframe.
6Unplug the electrical connector(s) to
disconnect the oxygen sensor and, where
fitted, the oil level sensor wiring - unclip the
connectors to release the wiring where
necessary.
7Where the vehicle is fitted with automatic
transmission, trace the fluid cooler lines from
the transmission to the radiator, and release
them from any clips etc, so that they have as
much movement as possible.
8Remove the auxiliary drivebelt cover (see
Chapter 1).
9Unscrew the nuts to disconnect the
exhaust system front downpipe from the
manifold, then either unhook all the system’s
rubber mountings and withdraw the complete
exhaust system from under the vehicle, or
remove only the downpipe/catalytic converter
(see Chapter 4 for details).
10Unscrew the sump-to-transmission bolts,
also any securing the engine/transmission
lower adaptor plate.
11Unplugging the two electrical connectors,
disconnecting the vacuum hose (where fitted)
and disconnecting the crankcase breather
hose from the cylinder head cover, remove
the complete air cleaner assembly with the air
mass meter, the resonator and the plenum
chamber (see Chapter 4).

the gasket, move the pump into the correct
position, and tighten its bolts to the specified
torque wrench setting.
14Check that the pump is correctly located;
if necessary, unbolt it again, and repeat the
full procedure to ensure that the pump is
correctly aligned.
15Fit a new crankshaft right-hand oil seal
(see Section 20).
16Using grease to stick the gasket in place
on the pump, refit the pick-up/strainer pipe,
tightening its screws and nut to their specified
torque wrench settings (see illustration).
17The remainder of reassembly is the
reverse of the removal procedure, referring to
the relevant text for details where required.
1Drain the cooling system (see Chapter 1).
Disconnect the coolant hoses from the oil
cooler.
2Unscrew the oil filter (see Chapter 1) -
catch any escaping oil in a drip tray.
3Unscrew the filter adaptor from the oil
pump, and withdraw the oil cooler; note how
its unions are aligned, and be prepared for oil
loss from the cooler.
4Refitting is the reverse of the removal
procedure, noting the following points:(a) Renew all O-rings and seals disturbed on
removal.
(b) Align the cooler’s unions as noted on
removal, and tighten the adaptor to the
specified torque wrench setting.
(c) Refill the cooling system (see Chapter 1).
(d) Refit the oil filter, then check the engine
oil level, and top-up as necessary (see
Chapter 1).
(e) Check for signs of oil or coolant leaks once
the engine has been restarted and warmed-
up to normal operating temperature.
1With the vehicle parked on firm level
ground, open the bonnet and disconnect the
battery negative (earth) lead - see Chapter 5,
Section 1.
2Raise the front of the vehicle, and support it
securely on axle stands.
3Undo the two screws, and remove the
sensor’s cover from the front of the sump
(see illustration).
4Unplug the wiring from the sensor (see
illustration). Where necessary, unplug the
electrical connector to disconnect the sensor
wiring, and unclip the connector to release
the wiring from the vehicle.
5Unscrew the sensor, and quickly plug the
sump aperture to minimise oil loss; note the
sensor’s seal.6Refitting is the reverse of the removal
procedure; renew the sensor’s seal if it is
worn or damaged, and tighten the sensor to
the specified torque wrench setting. Check
the engine oil level, and top-up as necessary
(see Chapter 1) - check for signs of oil leaks
once the engine has been restarted and
warmed-up to normal operating temperature.
1The switch is screwed into the rear of the
cylinder block, above the right-hand
driveshaft’s support bearing (see
illustration).
2With the vehicle parked on firm level
ground, open the bonnet and disconnect the
battery negative (earth) lead - see Chapter 5,
Section 1.
3Raise the front of the vehicle, and support it
securely on axle stands.
4Unplug the wiring from the switch, and
unscrew it; be prepared for some oil loss.
5Refitting is the reverse of the removal
procedure; apply a thin smear of suitable
sealant to the switch threads, and tighten it to
the specified torque wrench setting. Check
the engine oil level, and top-up as necessary
(see Chapter 1). Check for signs of oil leaks
once the engine has been restarted and
warmed-up to normal operating temperature.
Note:Don’t try to prise these seals out
without removing the oil pump or seal carrier -
the seals are too soft, and the amount of
space available is too small, for this to be
possible without considerable risk of damage
to the seal housing and/or the crankshaft
journal. Follow exactly the procedure given
below.

inner wing panel, release the engine
wiring loom and refit the power steering
fluid reservoir.
(g) Secure the engine wiring loom neatly to
the engine/transmission so that it cannot
be damaged as the unit is removed from
the vehicle.
14Unbolt both parts of the exhaust manifold
heat shield; unclip the coolant hose to allow
the upper part to be withdrawn.
15Remove the auxiliary drivebelt (see
Chapter 1).
16Unbolt the power steering pump (see
Chapter 10); secure it as far as possible
(without disconnecting the system’s hoses)
clear of the engine/transmission.
17Raise the vehicle and support it securely
on axle stands, then remove the front
roadwheels. Drain the cooling system and (if
the engine is to be dismantled) drain the
engine oil and remove the oil filter (see
Chapter 1). Also drain the transmission as
described in the relevant Part of Chapter 7.
18Withdraw the lower part of the exhaust
manifold heat shield.
19Unscrew the nuts to disconnect the
exhaust system front downpipe from the
manifold, then unhook all the system’s rubber
mountings and withdraw the complete
exhaust system from under the vehicle (see
Chapter 4 for details).
20Where the vehicle is fitted with manual
transmission, mark their positions, then
disconnect the gearchange linkage and
transmission support rods from the rear of the
transmission. Unscrew the retaining nuts, and
withdraw the gear linkage heat shield from the
underbody. Unbolt the rear end of the linkage
from the underbody, swivel the linkage around
to the rear, and tie it to the underbody (see
Chapter 7, Part A, for details).
21Disconnect both anti-roll bar links from
their respective suspension strut - note the
flexible brake hose bracket attached to each
link stud - and both track rod ends from their
steering knuckles. Unfasten the clamp bolt
securing each front suspension lower arm
balljoint to its steering knuckle (see Chap-
ter 10 for details). Check that both balljoints
can be released from the knuckle assemblies
when required, but leave them in place for thetime being, secured by the clamp bolts if
necessary.
22Where the vehicle is fitted with air
conditioning, unbolt the accumulator/
dehydrator from the subframe; secure it as far
as possible (without disconnecting the
system’s hoses) clear of the engine/
transmission.
Warning: Do not disconnect the
refrigerant hoses.
23Unbolt the steering gear from the
subframe; if the bolts are not accessible from
above, a Ford service tool will be required to
reach them from underneath the vehicle (see
Chapter 10 for details).
24Unscrew the two bolts securing the power
steering system pipes to the right-hand side
of the subframe.
25Hold the radiator in its raised position, by
inserting split pins through the holes in the
rear of the engine compartment front
crossmember and into the radiator’s upper
mounting extensions. Unbolt the radiator
mounting brackets from the subframe; note
that they are handed, and are marked to
ensure correct refitting (see illustrations).
Collect and store the bottom mounting
rubbers for safekeeping, noting which way up
they are fitted.
26Unbolt the engine/transmission rear
mounting from the subframe - where the
vehicle is fitted with automatic transmission, a
separate damper may be fitted beneath the
subframe, which must be unbolted to reach
the mounting’s fasteners. Where the vehicle is
fitted with manual transmission, also unscrew
the mounting centre bolt, and unbolt the
mounting bracket from the transmission.
27Unscrew the engine/transmission front
mounting centre bolt, and unbolt the
mounting from the subframe, noting the
location of the wiring connector bracket.
28Use white paint or similar (do not use a
sharp-pointed scriber, which might break the
underbody protective coating and cause
rusting) to mark the exact relationship of the
subframe to the underbody. Unscrew the four
mounting bolts from the subframe (note their
different-sized washers - see also illus-tration 4.47A) and allow the subframe to hang
down on the suspension lower arm balljoints.
Disconnect the balljoints one at a time from
the steering knuckle assemblies (see Chap-
ter 10) and lower the subframe to the ground;
withdraw the subframe from under the
vehicle.
29Marking or labelling all components as
they are disconnected (see paragraph 5
above) and catching as much as possible of
the escaping coolant in the drain tray,
disconnect the cooling system hoses and
pipes as follows - refer to Chapter 3 for further
details, if required:
(a) Remove the radiator top hose.
(b) Remove the (heater) hose running from
the thermostat to the engine
compartment bulkhead union.
(c) Disconnect from the thermostat the hose
running to the expansion tank - secure the
hose clear of the working area.
(d) Disconnect from the thermostat the
coolant hose/pipe which runs to the
radiator bottom hose.
(e) Disconnect the radiator bottom hose from
the radiator union, from the (sump) heater
coolant pipe and from the water pump
union - secure the hose clear of the
working area.
(f) Unbolt the (heater) coolant pipe from the
sump, trace the pipe/hose round to the
engine compartment bulkhead union,
disconnecting (where fitted) the oil cooler
hoses from the cooler unions, then
remove it.
(g) Unless the vehicle has air conditioning
fitted, secure the radiator as far forwards
as possible while it is in its raised position;
if air conditioning is fitted, remove the
radiator completely (see Chapter 3).
30Where the vehicle is fitted with air
conditioning, unplug the compressor’s
electrical connector, and unbolt the
compressor from the engine (see
illustration). Secure it as far as possible
(without disconnecting the system’s hoses)
clear of the engine/transmission.
Warning: Do not disconnect the
refrigerant hoses.

grinding or head resurfacing. Use
compressed air, if available, to blow out all the
oil holes and passages.
2Beginning at one end of the head, lubricate
and install the first valve. Apply molybdenum
disulphide-based grease or clean engine oil to
the valve stem, and refit the valve. Where the
original valves are being re-used, ensure that
each is refitted in its original guide. If new
valves are being fitted, insert them into the
locations to which they have been ground.
3Fit the plastic protector supplied with new
valve spring lower seat/stem oil seals to the
end of the valve stem, then put the new seal
squarely on top of the guide, and leave it
there; the action of refitting the valve spring
presses the lower seat/stem oil seal into place
(see illustration).
4Refit the valve spring and upper seat.
5Compress the spring with a valve spring
compressor, and carefully install the collets in
the stem groove. Apply a small dab of grease
to each collet to hold it in place if necessary
(see illustration). Slowly release the
compressor, and make sure the collets seat
properly.
6When the valve is installed, place the
cylinder head flat on the bench and, using a
hammer and interposed block of wood, tap
the end of the valve stem gently, to settle the
components.7Repeat the procedure for the remaining
valves. Be sure to return the components to
their original locations - don’t mix them up!
8Refit the hydraulic tappets (Part A of this
Chapter, Section 13).
Note:Always check first what replacement
parts are available before planning any
overhaul operation; refer to Section 1 of this
Part. A Ford dealer, or a good engine
reconditioning specialist/automotive parts
supplier, may be able to suggest alternatives
which will enable you to overcome the lack of
replacement parts.
Note:While this task is theoretically possible
when the engine is in place in the vehicle, in
practice, it requires so much preliminary
dismantling, and is so difficult to carry out due
to the restricted access, that owners are
advised to remove the engine from the vehicle
first. In addition to the new gaskets and other
replacement parts required, a hoist will be
needed. Alternatively, an adjustable engine
support bar, fitting into the water drainchannels on each side of the bonnet aperture,
and having a hook which will engage the
engine lifting eyes and allow the height of the
engine to be adjusted, could be used. Lifting
equipment such as this can be hired from
most tool hire shops - be sure that any such
equipment is rated well in excess of the
combined weight of the engine/transmission
unit.
1Remove the cylinder head (Part A of this
Chapter, Section 14).
2Bolt lifting eyes to suitable points on the
engine and transmission, then attach the
lifting equipment so that the engine/
transmission unit is supported securely.
3Remove the sump (Part A of this Chapter,
Section 15).
4Undo the screws securing the oil pump
pick-up/strainer pipe to the pump, then
unscrew the four nuts, and withdraw the oil
pump pick-up/strainer pipe and oil baffle (see
illustration).
5Temporarily refit the crankshaft pulley, so
that the crankshaft can be rotated. Note that
each piston/connecting rod assembly can be
identified by its cylinder number (counting
from the timing belt end of the engine) etched
into the flat-machined surface of both the
connecting rod and its cap. The numbers are
visible from the front (exhaust side) of the
engine. Furthermore, each piston has an
arrow stamped into its crown, pointing
towards the timing belt end of the engine. If
no marks can be seen, make your own before
disturbing any of the components, so that you
can be certain of refitting each
piston/connecting rod assembly the right way
round, to its correct (original) bore, with the
cap also the right way round (see
illustrations).
6Use your fingernail to feel if a ridge has

3•2 Cooling, heating and air conditioning systems
Engine cooling system
All vehicles covered by this manual employ
a pressurised engine cooling system with
thermostatically-controlled coolant circu-
lation. A water pump mounted on the drivebelt
end of the cylinder block/crankcase pumps
coolant through the engine. The coolant flows
around each cylinder and toward the
transmission end of the engine. Cast-in
coolant passages direct coolant around the
inlet and exhaust ports, near the spark
plug areas and close to the exhaust valve
guides.
A wax pellet type thermostat is located in a
housing at the transmission end of the engine.
During warm-up, the closed thermostat
prevents coolant from circulating through the
radiator. Instead, it returns through the
coolant metal pipe running across the front of
the engine to the radiator bottom hose and
the water pump. The supply to the heater is
made from the rear of the thermostat housing.
As the engine nears normal operating
temperature, the thermostat opens and allows
hot coolant to travel through the radiator,
where it is cooled before returning to the
engine.
The cooling system is sealed by a pressure-
type filler cap in the expansion tank. The
pressure in the system raises the boiling point
of the coolant, and increases the cooling
efficiency of the radiator. When the engine is
at normal operating temperature, the coolant
expands, and the surplus is displaced into the
expansion tank. When the system cools, the
surplus coolant is automatically drawn back
from the tank into the radiator.
Warning: DO NOT attempt to
remove the expansion tank filler
cap, or to disturb any part of the
cooling system, while it or the
engine is hot, as there is a very great risk
of scalding. If the expansion tank filler cap
must be removed before the engine and
radiator have fully cooled down (even
though this is not recommended) the
pressure in the cooling system must first
be released. Cover the cap with a thick
layer of cloth, to avoid scalding, and slowly
unscrew the filler cap until a hissing sound
can be heard. When the hissing hasstopped, showing that pressure is
released, slowly unscrew the filler cap
further until it can be removed; if more
hissing sounds are heard, wait until they
have stopped before unscrewing the cap
completely. At all times, keep well away
from the filler opening.
Warning: Do not allow antifreeze
to come in contact with your
skin, or with the painted surfaces
of the vehicle. Rinse off spills
immediately with plenty of water. Never
leave antifreeze lying around in an open
container, or in a puddle in the driveway or
on the garage floor. Children and pets are
attracted by its sweet smell, but antifreeze
is fatal if ingested.
Warning: If the engine is hot, the
electric cooling fan may start
rotating even if the engine is not
running, so be careful to keep
hands, hair and loose clothing well clear
when working in the engine compartment.
Heating system
The heating system consists of a blower fan
and heater matrix (radiator) located in the
heater unit, with hoses connecting the heater
matrix to the engine cooling system. Hot
engine coolant is circulated through the
heater matrix. When the heater temperature
control on the facia is operated, a flap door
opens to expose the heater box to the
passenger compartment. When the blower
control is operated, the blower fan forces air
through the unit according to the setting
selected.
Air conditioning system
See Section 11.
Warning: Do not allow antifreeze to come in
contact with your skin, or with the painted
surfaces of the vehicle. Rinse off spills
immediately with plenty of water. Antifreeze is
highly toxic if ingested. Never leave antifreeze
lying around in an open container, or in
puddles on the floor; children and pets are
attracted by its sweet smell, and may drink it.
Check with local authorities about disposing
of used antifreeze - many have collection
centres which will see that antifreeze is
disposed of safely.The cooling system should be filled with a
water/ethylene glycol-based antifreeze
solution, of a strength which will prevent
freezing down to at least -25°C, or lower if the
local climate requires it. Antifreeze also
provides protection against corrosion, and
increases the coolant boiling point.
The cooling system should be maintained
according to the schedule described in
Chapter 1. If antifreeze is used that is not to
Ford’s specification, old or contaminated
coolant mixtures are likely to cause damage,
and encourage the formation of corrosion and
scale in the system. Use distilled water with
the antifreeze, if available - if not, be sure to
use only soft water. Clean rainwater is
suitable.
Before adding antifreeze, check all hoses
and hose connections, because antifreeze
tends to leak through very small openings.
Engines don’t normally consume coolant, so if
the level goes down, find the cause and
correct it.
The exact mixture of antifreeze-to-water
which you should use depends on the
relative weather conditions. The mixture
should contain at least 40% antifreeze, but
not more than 70%. Consult the mixture
ratio chart on the antifreeze container
before adding coolant. Hydrometers are
available at most automotive accessory
shops to test the coolant. Use antifreeze
which meets the vehicle manufacturer’s
specifications.
Note:Refer to the warnings given in Section 1
of this Chapter before starting work.
1If the checks described in Chapter 1 reveal
a faulty hose, it must be renewed as follows
(see illustration).
2First drain the cooling system (see Chap-
ter 1); if the antifreeze is not due for renewal,
the drained coolant may be re-used, if it is
collected in a clean container.
3To disconnect any hose, use a pair of pliers
to release the spring clamps (or a screwdriver
to slacken screw-type clamps), then move
them along the hose clear of the union.
Carefully work the hose off its stubs. The
hoses can be removed with relative ease
when new - on an older car, they may have
stuck.
