17.4 Removing the automatic transmission
dipstick from its tube7.6A “MIN” and “MAX” marks on the
dipstick7.6B Adding automatic transmission fluid
through the dipstick tube
Every 10 000 miles
1The level of the automatic transmission fluid
should be carefully maintained. Low fluid level
can lead to slipping or loss of drive, while
overfilling can cause foaming, loss of fluid and
transmission damage.
2The transmission fluid level should only be
checked when the transmission is hot (at its
normal operating temperature). If the vehicle
has just been driven over 10 miles (15 miles in
a cold climate), and the fluid temperature is
160 to 175°F, the transmission is hot.
Caution: If the vehicle has just
been driven for a long time at
high speed or in city traffic in hot
weather, or if it has been pulling
a trailer, an accurate fluid level reading
cannot be obtained. In these
circumstances, allow the fluid to cool
down for about 30 minutes.
3Park the vehicle on level ground, apply the
handbrake, and start the engine. While the
engine is idling, depress the brake pedal and
move the selector lever through all the gear
ranges three times, beginning and ending in
“P”.
4Allow the engine to idle for one minute, then
(with the engine still idling) remove the dipstick
from its tube (see illustration). Note the
condition and colour of the fluid on the dipstick.
5Wipe the fluid from the dipstick with a clean
rag, and re-insert it into the filler tube until the
cap seats.
6Pull the dipstick out again, and note the
fluid level. The level should be between the
“MIN” and “MAX” marks. If the level is on the
“MIN” mark, stop the engine, and add the
specified automatic transmission fluid through
the dipstick tube, using a clean funnel if
necessary (see illustrations). It is important
not to introduce dirt into the transmission
when topping-up.
7Add the fluid a little at a time, and keep
checking the level as previously described
until it is correct.8The need for regular topping-up of the
transmission fluid indicates a leak, which
should be found and rectified without delay.
9The condition of the fluid should also be
checked along with the level. If the fluid at the
end of the dipstick is black or a dark reddish-
brown colour, or if it has a burned smell, the
fluid should be changed. If you are in doubt
about the condition of the fluid, purchase
some new fluid, and compare the two for
colour and smell.
1Check the operation of all external lights
and indicators (front and rear).
2Check for satisfactory operation of the
instrument panel, its illumination and warning
lights, the switches and their function lights.
3Check the horn(s) for satisfactory operation.
4Check all other electrical equipment for
satisfactory operation.
5Check all electrical wiring in the engine
compartment for correct routing, and for any
signs of physical or heat-damage or chafing.
Warning: Certain precautions
must be followed when checking
and servicing the battery.
Hydrogen gas, which is highly
flammable, is always present in the battery
cells, so keep lighted tobacco and all other
open flames and sparks away from the
battery. The electrolyte inside the battery
is actually dilute sulphuric acid, which will
cause injury if splashed on your skin or in
your eyes. It will also ruin clothes and
painted surfaces. When disconnecting the
battery, always detach the negative (earth)
lead first and connect it last!
Note: Before disconnecting the battery, refer
to Section 1 of Chapter 5.

9.1 Tools and materials required for
battery maintenance
1Face shield/safety goggles- When
removing corrosion with a brush, the acidic
particles can easily fly up into your eyes
2Baking soda- A solution of baking soda
and water can be used to neutralise corrosion
3Petroleum jelly- A layer of this on the
battery terminals will help prevent corrosion
4Battery terminal/lead cleaner- This wire
brush cleaning tool will remove all traces of
corrosion from the battery terminals and lead
clamps
5Treated felt washers- Placing one of
these on each terminal, directly under the
lead clamps, will help prevent corrosion
6Puller- Sometimes the lead clamps are
very difficult to pull off the terminals, even
after the nut has been completely slackened.
This tool pulls the clamp straight up and off
the terminal without damage
7Battery terminal/lead cleaner- Here is
another cleaning tool which is a slightly
different version of number 4 above, but does
the same thing
8Rubber gloves- Another safety item to
consider when servicing the battery;
remember, that’s acid inside the battery!

comb” or compressed air to clean the
condenser.
Warning: Wear eye protection
when using compressed air!
(d) Check that the drain tube from the front
of the evaporator is clear - note that it is
normal to have clear fluid (water) dripping
from this while the system is in operation,
to the extent that quite a large puddle can
be left under the vehicle when it is parked.
2It’s a good idea to operate the system forabout 30 minutes at least once a month,
particularly during the winter. Long term
non-use can cause hardening, and
subsequent failure, of the seals.
3Because of the complexity of the air
conditioning system and the special
equipment necessary to service it, in-depth
fault diagnosis and repairs are not included in
this manual. For more complete information
on the air conditioning system, refer to the
Haynes Automotive Heating and Air
Conditioning Manual.
4The most common cause of poor cooling is
simply a low system refrigerant charge. If a
noticeable drop in cool air output occurs, the
following quick check will help you determine
if the refrigerant level is low.
5Warm the engine up to normal operating
temperature.
6Place the air conditioning temperature
selector at the coldest setting, and put the
blower at the highest setting. Open the doors
- to make sure the air conditioning system
doesn’t cycle off as soon as it cools the
passenger compartment.
7With the compressor engaged - the clutch
will make an audible click, and the centre of
the clutch will rotate - feel the inlet and outlet
pipes at the compressor. One side should be
cold, and one hot. If there’s no perceptible
difference between the two pipes, there’s
something wrong with the compressor or the
system. It might be a low charge - it might be
something else. Take the vehicle to a dealer
service department or an automotive air
conditioning specialist.1Make sure that you have all the necessary
tools before you begin this procedure (see
illustration). You should also have plenty of
rags or newspapers handy, for mopping up
any spills.
2To avoid any possibility of scalding, and to
protect yourself from possible skin irritants
and other harmful contaminants in used
engine oils, it is advisable to wear gloves
when carrying out this work.
3Access to the underside of the vehicle is
greatly improved if the vehicle can be lifted on
a hoist, driven onto ramps, or supported by
axle stands.
Warning: Do not work under a
vehicle which is supported only
by an hydraulic or scissors-type
jack, or by bricks, blocks of
wood, etc.
4If this is your first oil change, get under the
vehicle and familiarise yourself with the
position of the engine oil drain plug, which is
located at the rear of the sump. The engine
and exhaust components will be warm during
the actual work, so try to anticipate any
potential problems while the engine and
accessories are cool.
5The oil should preferably be changed when
the engine is still fully warmed-up to normal
operating temperature, just after a run (the
needle on the temperature gauge should be in
the “Normal” sector of the gauge); warm oil
and sludge will flow out more easily. Park the
vehicle on firm, level ground, apply the
handbrake firmly, then select 1st or reverse
gear (manual transmission) or the “P” position
(automatic transmission). Open the bonnet
and remove the engine oil filler cap from the
cylinder head cover, then remove the oil level
dipstick from its tube (see Section 3).
6Raise the front of the vehicle, and support it
securely on axle stands. Remove the front
right-hand roadwheel to provide access to the
oil filter; if the additional working clearance is
required, remove also the auxiliary drivebelt
cover (two fasteners).

15.1 These tools are required when
changing the engine oil and filter
1Drain pan- It should be fairly shallow in
depth, but wide to prevent spills
2Rubber gloves- When removing the drain
plug and filter, it is inevitable that you will get
oil on your hands (the gloves will prevent
burns from hot oil)
3Breaker bar- Sometimes the oil drain plug
is pretty tight, and a long breaker bar is
needed to loosen it
4Socket- To be used with the breaker bar
or a ratchet (must be the correct size to fit the
drain plug)
5Filter wrench- This is a metal band-type
wrench, which requires clearance around the
filter to be effective
6Filter wrench- This type fits on the
bottom of the filter, and can be turned with a
ratchet or breaker bar (different size wrenches
are available for different types of filters)
15.7 Use the correct-size spanner or
socket to remove the oil drain plug and
avoid rounding it off15.9 Since the oil filter is usually on very
tight, you’ll need a special wrench for
removal. DO NOT use the wrench to
tighten the new filter. Pack rag under the
filter before removal to minimise the mess

Frequent oil changes are the
best preventive maintenance

brake shoes is not less than the
recommendation given in the Specifications.
14If it is difficult to determine the exact
thickness of the brake shoe linings, or if you
are at all concerned about the condition of the
shoes, then remove the rear drums for a more
comprehensive inspection (refer to Chapter 9)
(see illustration).
15With the drum removed, check the shoe
return and hold-down springs for correct
installation, and check the wheel cylinders for
leakage of brake fluid. Check the friction
surface of the brake drums for scoring and
discoloration. If excessive, the drum should
be resurfaced or renewed.
16Before refitting the wheels, check all
brake lines and hoses (refer to Chapter 9). On
completion, apply the handbrake and check
that the rear wheels are locked. The
handbrake is self-adjusting, and no manual
adjustment is possible.
1Check that the doors, bonnet and
tailgate/boot lid close securely. Check that
the bonnet safety catch operates correctly.
Check the operation of the door check straps.
2Lubricate the hinges, door check straps,
the striker plates and the bonnet catch
sparingly with a little oil or grease.1Apply the handbrake.
2Remove the wheel covers, using the flat
end of the wheelbrace supplied in the tool kit
(on models with the RS trim kit, it will be
necessary to unscrew the retaining bolts with
the special key).
3Check that the roadwheel nuts are tightened
to the specified torque wrench setting.
4Refit the wheel covers.
Check the operation and
performance of the braking
system
1Make sure that the vehicle does not pull to
one side when braking, and that the wheels
do not lock prematurely when braking hard.
2Check that there is no vibration through the
steering when braking.
3Check that the handbrake operates
correctly, without excessive movement of the
lever, and that it holds the vehicle stationary
on a slope.
4With the engine switched off, test the
operation of the brake servo unit as follows.
Depress the footbrake four or five times to
exhaust the vacuum, then start the engine. As
the engine starts, there should be a noticeable
“give” in the brake pedal as vacuum builds
up. Allow the engine to run for at least two
minutes, and then switch it off. If the brake
pedal is now depressed again, it should be
possible to detect a hiss from the servo as the
pedal is depressed. After about four or five
applications, no further hissing should be
heard, and the pedal should feel considerably
harder.
Steering and suspension
5Check for any abnormalities in the steering,
suspension, handling or road “feel”.
6Drive the vehicle, and check that there are
no unusual vibrations or noises.
7Check that the steering feels positive, with
no excessive sloppiness or roughness, andcheck for any suspension noises when
cornering and driving over bumps.
Drivetrain
8Check the performance of the engine,
transmission and driveshafts.
9Check that the engine starts correctly, both
when cold and when hot.
10Listen for any unusual noises from the
engine and transmission.
11Make sure that the engine runs smoothly
when idling, and that there is no hesitation
when accelerating.
12On manual transmission models, check
that all gears can be engaged smoothly
without noise, and that the gear lever action is
not abnormally vague or “notchy”.
13On automatic transmission models, make
sure that all gearchanges occur smoothly
without snatching, and without an increase in
engine speed between changes. Check that
all the gear positions can be selected with the
vehicle at rest. If any problems are found, they
should be referred to a Ford dealer.
14Listen for a metallic clicking sound from
the front of the vehicle as the vehicle is driven
slowly in a circle with the steering on full-lock.
Carry out this check in both directions. If a
clicking noise is heard, this indicates wear in a
driveshaft joint, in which case renew the joint
if necessary.
Clutch
15Check that the clutch pedal moves
smoothly and easily through its full travel, and
that the clutch itself functions correctly, with
no trace of slip or drag. If the movement is
uneven or stiff in places, check that the cable
is routed correctly, with no sharp turns.
16Inspect both ends of the clutch inner
cable, both at the gearbox end and inside the
car, for signs of wear and fraying.
17Check the pedal stroke as described in
Chapter 8, Section 3, and adjust if necessary.
Instruments and electrical
equipment
18Check the operation of all instruments
and electrical equipment.
19Make sure that all instruments read
correctly, and switch on all electrical
equipment in turn, to check that it functions
properly.

1The air entering the vehicle’s ventilation
system is passed through a very fine pleated-
paper air filter element, which removes
particles of pollen, dust and other airborne
foreign matter. To ensure its continued
effectiveness, this filter’s element must be
renewed at regular intervals.2Remove the left-hand side windscreen
wiper arm (Chapter 12).
3Prise off their trim caps, then unscrew the two
screws securing the windscreen edge of the cowl
grille panel; open the bonnet and remove the
remaining three retaining screws (see illustration).
4Peel back the rubber seal and withdraw the
cowl grille panel.
5Releasing the clip at each end, lift out the
pollen filter housing, and withdraw the
element (see illustrations).6Wipe out the ventilation system intake and
the filter housing, removing any leaves, dead
insects etc.
7If carrying out a routine service, the element
must be renewed regardless of its apparent
condition. If you are checking the element for
any other reason, inspect its front surface; if it
is very dirty, renew the element. If it is only
moderately dusty, it can be re-used by
blowing it clean from the rear to the front
surface with compressed air. Because it is a
27 Ventilation system pollen
filter renewal

pleated-paper type filter, it cannot be washed
or re-oiled. If it cannot be cleaned
satisfactorily with compressed air, discard
and renew it.
Warning: Wear eye protection
when using compressed air!
8Refitting is the reverse of the removal
procedure; ensure that the element and
housing are securely seated, so that unfiltered
air cannot enter the passenger compartment.
Note:If the antifreeze used is Ford’s own, or of
similar quality, the coolant need not be
renewed for the life of the vehicle. If the
vehicle’s history is unknown, if antifreeze of
lesser quality is known to be in the system, or
simply if you prefer to follow conventional
servicing intervals, the coolant should be
changed periodically (typically, every 2 years)
as described here. Refer also to the
information in Section 2 of this Chapter.
Warning: Do not allow antifreeze
to come in contact with your skin
or painted surfaces of the
vehicle. Flush contaminated areas
immediately with plenty of water. Don’t
store new coolant, or leave old coolant
lying around, where it’s accessible to
children or pets - they’re attracted by its
sweet smell. Ingestion of even a small
amount of coolant can be fatal! Wipe up
garage-floor and drip-pan spills
immediately. Keep antifreeze containers
covered, and repair cooling system leaks
as soon as they’re noticed.
Warning: Never remove the
expansion tank filler cap when
the engine is running, or has just
been switched off, as the cooling system
will be hot, and the consequent escaping
steam and scalding coolant could cause
serious injury.
Coolant draining
Warning: Wait until the engine is
cold before starting this
procedure.1To drain the system, first remove the
expansion tank filler cap (see Section 3).
2If the additional working clearance is
required, raise the front of the vehicle and
support it securely on axle stands.
3Remove the radiator undershield (eight or
nine screws), then place a large drain tray
underneath, and unscrew the radiator drain
plug; direct as much of the escaping coolant
as possible into the tray (see illustrations).
System flushing
4With time, the cooling system may
gradually lose its efficiency, as the radiator
core becomes choked with rust, scale
deposits from the water, and other sediment
(refer also to the information at the start of
Section 2). To minimise this, as well as using
only good-quality antifreeze and clean soft
water, the system should be flushed as
follows whenever any part of it is disturbed,
and/or when the coolant is renewed.
5With the coolant drained, refit the drain plug
and refill the system with fresh water. Refit the
expansion tank filler cap, start the engine and
warm it up to normal operating temperature,
then stop it and (after allowing it to cool down
completely) drain the system again. Repeat as
necessary until only clean water can be seen
to emerge, then refill finally with the specified
coolant mixture.
6If only clean, soft water and good-quality
antifreeze (even if not to Ford’s specification)
has been used, and the coolant has been
renewed at the suggested intervals, the above
procedure will be sufficient to keep clean the
system for a considerable length of time. If,however, the system has been neglected, a
more thorough operation will be required, as
follows.
7First drain the coolant, then disconnect the
radiator top and bottom hoses. Insert a
garden hose into the top hose, and allow
water to circulate through the radiator until it
runs clean from the bottom outlet.
8To flush the engine, insert the garden hose
into the thermostat water outlet, and allow
water to circulate until it runs clear from the
bottom hose. If, after a reasonable period, the
water still does not run clear, the radiator
should be flushed with a good proprietary
cleaning agent.
9In severe cases of contamination, reverse-
flushing of the radiator may be necessary. To
do this, remove the radiator (Chapter 3), invert
it, and insert the garden hose into the bottom
outlet. Continue flushing until clear water runs
from the top hose outlet. A similar procedure
can be used to flush the heater matrix.
10The use of chemical cleaners should be
necessary only as a last resort. Normally,
regular renewal of the coolant will prevent
excessive contamination of the system.
Coolant filling
11With the cooling system drained and
flushed, ensure that all disturbed hose unions

are correctly secured, and that the radiator
drain plug is securely tightened. Refit the
radiator undershield, noting that it is located
by three clips at its front edge; tighten the
retaining screws securely (see illustration). If
it was raised, lower the vehicle to the ground.
12Prepare a sufficient quantity of the
specified coolant mixture (see below); allow
for a surplus, so as to have a reserve supply
for topping-up.
13Slowly fill the system through the
expansion tank; since the tank is the highest
point in the system, all the air in the system
should be displaced into the tank by the rising
liquid. Slow pouring reduces the possibility of
air being trapped and forming air-locks.
14Continue filling until the coolant level
reaches the expansion tank “MAX” level line,
then cover the filler opening to prevent
coolant splashing out.
15Start the engine and run it at idle speed,
until it has warmed-up to normal operating
temperature and the radiator electric cooling
fan has cut in; watch the temperature gauge
to check for signs of overheating. If the level in
the expansion tank drops significantly, top-up
to the “MAX” level line, to minimise the
amount of air circulating in the system.
16Stop the engine, allow it to cool down
completely(overnight, if possible), then
uncover the expansion tank filler opening and
top-up the tank to the “MAX” level line. Refit
the filler cap, tightening it securely, and washoff any spilt coolant from the engine
compartment and bodywork.
17After refilling, always check carefully all
components of the system (but especially any
unions disturbed during draining and flushing)
for signs of coolant leaks. Fresh antifreeze has
a searching action, which will rapidly expose
any weak points in the system.
18 Note:If, after draining and refilling the
system, symptoms of overheating are found
which did not occur previously, then the fault
is almost certainly due to trapped air at some
point in the system, causing an air-lock and
restricting the flow of coolant; usually, the air
is trapped because the system was refilled too
quickly. In some cases, air-locks can be
released by tapping or squeezing the various
hoses. If the problem persists, stop the engine
and allow it to cool down completely, before
unscrewing the expansion tank filler cap or
disconnecting hoses to bleed out the trapped
air.
Antifreeze mixture
19If the antifreeze used is not to Ford’s
specification, it should always be renewed at
the suggested intervals. This is necessary not
only to maintain the antifreeze properties, but
also to prevent the corrosion which would
otherwise occur as the corrosion inhibitors
become progressively less effective. Always
use an ethylene glycol-based antifreeze which
is suitable for use in mixed-metal cooling
systems.
20If the antifreeze used is to Ford’s
specification, the levels of protection it affords
are indicated in the Specifications Section of
this Chapter. To give the recommended
standardmixture ratio for this antifreeze, 40%
(by volume) of antifreeze must be mixed with
60% of clean, soft water; if you are using any
other type of antifreeze, follow its
manufacturer’s instructions to achieve the
correct ratio. It is best to make up slightly
more than the system’s specified capacity, so
that a supply is available for subsequent
topping-up.
21Before adding antifreeze, the cooling
system should be completely drained,
preferably flushed, and all hoses checked forcondition and security. As noted earlier, fresh
antifreeze will rapidly find any weaknesses in
the system.
22After filling with antifreeze, a label should
be attached to the expansion tank, stating the
type and concentration of antifreeze used,
and the date installed. Any subsequent
topping-up should be made with the same
type and concentration of antifreeze. If
topping-up using antifreeze to Ford’s
specification, note that a 50/50 mixture is
permissible, purely for convenience.
23Do not use engine antifreeze in the
windscreen/tailgate washer system, as it will
damage the vehicle’s paintwork. A screen
wash additive should be added to the washer
system in its maker’s recommended
quantities.
General cooling system checks
24The engine should be cold for the cooling
system checks, so perform the following
procedure before driving the vehicle, or after it
has been shut off for at least three hours.
25Remove the expansion tank filler cap (see
Section 3), and clean it thoroughly inside and
out with a rag. Also clean the filler neck on the
expansion tank. The presence of rust or
corrosion in the filler neck indicates that the
coolant should be changed. The coolant
inside the expansion tank should be relatively
clean and transparent. If it is rust- coloured,
drain and flush the system, and refill with a
fresh coolant mixture.
26Carefully check the radiator hoses and
heater hoses along their entire length; renew
any hose which is cracked, swollen or
deteriorated (see Section 12).
27Inspect all other cooling system
components (joint faces, etc.) for leaks. A leak
in the cooling system will usually show up as
white- or rust-coloured deposits on the area
adjoining the leak. Where any problems of this
nature are found on system components,
renew the component or gasket with
reference to Chapter 3.
28Clean the front of the radiator with a soft
brush to remove all insects, leaves, etc,
embedded in the radiator fins. Be careful not
to damage the radiator fins, or cut your fingers
on them.

1The air filter element is located in the air
cleaner assembly on the left-hand side of the
engine compartment. Release the clips, and
lift the air cleaner cover (see illustrations). If
the additional working clearance is required,
unclip the cover from the air mass meter, and
withdraw it completely.
2Lift out the element, and wipe out thehousing (see illustration). Check that no
foreign matter is visible, either in the air intake
or in the air mass meter.
3If carrying out a routine service, the element
must be renewed regardless of its apparent
condition; note that the small foam filter in the
rear right-hand corner of the air cleaner
housing must be cleaned whenever the air
filter element is renewed (see Section 30).
4If you are checking the element for any
other reason, inspect its lower surface; if it is
oily or very dirty, renew the element. If it is
only moderately dusty, it can be re-used byblowing it clean from the upper to the lower
surface with compressed air. Because it is a
pleated-paper type filter, it cannot be washed
or re-oiled. If it cannot be cleaned
satisfactorily with compressed air, discard
and renew it.
Warning: Wear eye protection
when using compressed air!
Caution: Never drive the vehicle
with the air cleaner filter element
removed. Excessive engine wear could
result, and backfiring could even cause a
fire under the bonnet.
29 Air filter element renewal

check the cylinder head threads and tapered
sealing surfaces for signs of wear, excessive
corrosion or damage; if any of these
conditions is found, seek the advice of a Ford
dealer as to the best method of repair.
7As each plug is removed, examine it as
follows - this will give a good indication of the
condition of the engine. If the insulator nose of
the spark plug is clean and white, with no
deposits, this is indicative of a weak mixture.
8If the tip and insulator nose are covered
with hard black-looking deposits, then this is
indicative that the mixture is too rich. Should
the plug be black and oily, then it is likely that
the engine is fairly worn, as well as the mixture
being too rich.
9If the insulator nose is covered with light tan
to greyish-brown deposits, then the mixture is
correct, and it is likely that the engine is in
good condition.
10If you are renewing the spark plugs,
purchase the new plugs, then check each of
them first for faults such as cracked insulators
or damaged threads. Note also that,
whenever the spark plugs are renewed as a
routine service operation, the spark plug (HT)
leads should be checked as described below.
11The spark plug electrode gap is of
considerable importance as, if it is too large or
too small, the size of the spark and its
efficiency will be seriously impaired. The gap
should be set to the value given in the
Specifications Section of this Chapter. New
plugs will not necessarily be set to the correct
gap, so they should always be checked
before fitting.
12Special spark plug electrode gap
adjusting tools are available from most motor
accessory shops (see illustration).
13To set the electrode gap, measure the
gap with a feeler gauge, and then bend open,
or closed, the outer plug electrode until the
correct gap is achieved (see illustration). The
centre electrode should never be bent, as this
may crack the insulation and cause plug
failure, if nothing worse. If the outer electrode
is not exactly over the centre electrode, bend
it gently to align them.14Before fitting the spark plugs, check that
the threaded connector
sleeves at the top of the plugs are tight, and
that the plug exterior surfaces and threads are
clean. Brown staining on the porcelain,
immediately above the metal body, is quite
normal, and does not necessarily indicate a
leak between the body and insulator.
15On installing the spark plugs, first check
that the cylinder head thread and sealing
surface are as clean as possible; use a clean
rag wrapped around a paintbrush to wipe
clean the sealing surface. Apply a smear of
copper-based grease or anti-seize compound
to the threads of each plug, and screw them
in by hand where possible. Take extra care to
enter the plug threads correctly, as the
cylinder head is of aluminium alloy - it’s often
difficult to insert spark plugs into their holes
without cross-threading them.
16When each spark plug is started correctly
on its threads, screw it down until it just seats
lightly, then tighten it to the specified torquewrench setting (see illustration). If a torque
wrench is not available - and this is one case
where the use of a torque wrench is strongly
recommended - tighten each spark plug
through no more than1/16 of a turn. Do not
exceed the specified torque setting, and
NEVERovertighten these spark plugs - their
tapered seats mean they are almost
impossible to remove if abused.
17Reconnect the spark plug (HT) leads in
their correct order, using a twisting motion on
the boot until it is firmly seated on the end of
the spark plug and on the cylinder head cover.
Spark plug (HT) lead check
18The spark plug (HT) leads should be
checked whenever the plugs themselves are
renewed. Start by making a visual check of
the leads while the engine is running. In a
darkened garage (make sure there is
ventilation) start the engine and observe each
lead. Be careful not to come into contact with
any moving engine parts. If there is a break in
the lead, you will see arcing or a small spark
at the damaged area.
19The spark plug (HT) leads should be
inspected one at a time, to prevent mixing up
the firing order, which is essential for proper
engine operation. Each original lead should be
numbered to identify its cylinder. If the
number is illegible, a piece of tape can be
marked with the correct number, and
wrapped around the lead (the leads should be
numbered 1 to 4, with No 1 lead nearest the
timing belt end of the engine). The lead can
then be disconnected.
20Check inside the boot for corrosion, which
will look like a white crusty powder. Clean this
off as much as possible; if it is excessive, or if
cleaning leaves the metal connector too badly
corroded to be fit for further use, the lead
must be renewed. Push the lead and boot
back onto the end of the spark plug. The boot
should fit tightly onto the end of the plug - if it
doesn’t, remove the lead and use pliers
carefully to crimp the metal connector inside
the boot until the fit is snug.

31.12 Spark plug manufacturers
recommend using a wire-type gauge when
checking the gap - if the wire does not
slide between the electrodes with a slight
drag, adjustment is required31.13 To change the gap, bend the outer
electrode only, as indicated by the arrows,
and be very careful not to crack or chip the
porcelain insulator surrounding the centre
electrode31.16 Spark plugs have tapered seats - do
not overtighten them on refitting, or you
will not be able to get them out again
without risking damage to the plugs and
cylinder head
To avoid the possibility of cross-
threading a spark plug, fit a short piece
of rubber hose over the end of the
plug. The flexible hose acts as a
universal joint, to help align the plug
with the plug hole. Should the plug
begin to cross-thread, the hose will slip
on the spark plug, preventing thread
damage.

In-car engine repair procedures 2A•3

How to use this Chapter
This Part of Chapter 2 is devoted to repair
procedures possible while the engine is still
installed in the vehicle, and includes only the
Specifications relevant to those procedures.
Since these procedures are based on the
assumption that the engine is installed in the
vehicle, if the engine has been removed from
the vehicle and mounted on a stand, some of
the preliminary dismantling steps outlined will
not apply.
Information concerning engine/transmission
removal and refitting, and engine overhaul, can
be found in Part B of this Chapter, which also
includes the Specifications relevant to those
procedures.
General description - engine
The engine, also known by Ford’s internal
code name “Zetec” (formerly “Zeta”), is of
four-cylinder, in-line type, mounted
transversely at the front of the vehicle, with
the (clutch and) transmission on its left-hand
end (see illustrations).
Apart from the plastic timing belt covers and
the cast-iron cylinder block/crankcase, all
major engine castings are of aluminium alloy.
The crankshaft runs in five main bearings,
the centre main bearing’s upper half
incorporating thrustwashers to control
crankshaft endfloat. The connecting rods
rotate on horizontally-split bearing shells at
their big-ends. The pistons are attached to the
connecting rods by gudgeon pins which are an
interference fit in the connecting rod small-end
eyes. The aluminium alloy pistons are fitted
with three piston rings: two compression rings
and an oil control ring. After manufacture, the
cylinder bores and piston skirts are measured
and classified into three grades, which must be
carefully matched together, to ensure the
correct piston/cylinder clearance; no oversizes
are available to permit reboring.
The inlet and exhaust valves are each
closed by coil springs; they operate in guides
which are shrink-fitted into the cylinder head,
as are the valve seat inserts.Both camshafts are driven by the same
toothed timing belt, each operating eight
valves via self-adjusting hydraulic tappets,
thus eliminating the need for routine checking
and adjustment of the valve clearances. Each
camshaft rotates in five bearings that are line-bored directly in the cylinder head and the
(bolted-on) bearing caps; this means that the
bearing caps are not available separately
from the cylinder head, and must not be
interchanged with caps from another engine.
The water pump is bolted to the right-hand
