3 Engine oil and filter renewal
1
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.
2 To 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. 3
Access 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 (see “Jacking and Vehicle Support” ).
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. 4
If this is your first oil change, get under the
vehicle and familiarise yourself with the
position of the engine oil drain plug location in
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.
5 The 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 “Weekly Checks”).
6 Raise the front of the vehicle, and support it
securely on axle stands (see “Jacking and
Vehicle Support” ). Remove the front right-
hand roadwheel to provide access to the oil
1 Introduction
This Chapter is designed to help the home
mechanic maintain his/her vehicle for safety,
economy, long life and peak performance.
This Chapter contains a master
maintenance schedule, followed by Sections
dealing specifically with each task in the
schedule. Visual checks, adjustments,
component renewal and other helpful items
are included. Refer to the accompanying
illustrations of the engine compartment and
the underside of the vehicle for the locations
of the various components.
Servicing your vehicle in accordance with
the mileage/time maintenance schedule and
the following Sections will provide a planned
maintenance programme, which should result
in a long and reliable service life. This is a
comprehensive plan, so maintaining some
items but not others at the specified service
intervals will not produce the same results. As you service your vehicle, you will
discover that many of the procedures can -
and should - be grouped together, because of
the particular procedure being performed, or
because of the close proximity of two
otherwise-unrelated components to one
another. For example, if the vehicle is raised
for any reason, the exhaust should be
inspected at the same time as the suspension
and steering components.
The first step of this maintenance
programme is to prepare yourself before the
actual work begins. Read through all the Sections relevant to the work to be carried
out, then make a list and gather together all
the parts and tools required. If a problem is
encountered, seek advice from a parts
specialist or a dealer service department.
2 Intensive maintenance
1
If, from the time the vehicle is new, the
routine maintenance schedule is followed
closely, and frequent checks are made of fluid
levels and high-wear items, as suggested
throughout this manual, the engine will be
kept in relatively good running condition, and
the need for additional work will be minimised.
2 It is possible that there will be some times
when the engine is running poorly due to the
lack of regular maintenance. This is even more
likely if a used vehicle, which has not received
regular and frequent maintenance checks, is
purchased. In such cases, additional work
may need to be carried out, outside of the
regular maintenance intervals.
3 If engine wear is suspected, a compression
test (refer to Part A, B or C of Chapter 2) will
provide valuable information regarding the
overall performance of the main internal
components. Such a test can be used as a
basis to decide on the extent of the work to
be carried out. If, for example, a compression
test indicates serious internal engine wear,
conventional maintenance as described in this
Chapter will not greatly improve the
performance of the engine, and may prove a waste of time and money, unless extensive
overhaul work (Chapter 2D) is carried out first.
4
The following series of operations are those
often required to improve the performance of
a generally poor-running engine:
Primary operations
a) Clean, inspect and test the battery (See
“Weekly Checks”).
b) Check all the engine-related fluids (See
“Weekly Checks”).
c) Check the condition of the auxiliary drivebelt (Section 4).
d) Check and if necessary adjust the valve
clearances on HCS engines (Section 7).
e) Renew the spark plugs and clean and inspect the HT leads (Section 21).
f) Check the condition of the air cleaner filter element and renew if necessary
(Section 24).
g) Check and if necessary adjust the idle speed and mixture settings - where
applicable (Section 9).
h) Renew the fuel filter - fuel injection models (Section 30).
i) Check the condition of all hoses, and check for fluid leaks (Section 5).
5 If the above operations do not prove fully
effective, carry out the following operations:
Secondary operations
All the items listed under “Primary
operations”, plus the following: a) Check the charging system (Chapter 5A).
b) Check the ignition system (Chapter 5B).
c) Check the fuel system (Chapter 4A, 4B,
4C and 4D).
e) Renew the ignition HT leads (Section 21).

connections - remake the connections or
renew the leads if a fault is found. Use the
same techniques to ensure that all earth
points in the engine compartment provide
good electrical contact through clean, metal-
to-metal joints, and that all are securely
fastened. (In addition to the earth connection
at the engine lifting eye, and that from the
transmission to the body/battery, there are
others in various places, so check carefully).
8Refer to Section 21 for details of spark plug
(HT) lead checks.
7 Valve clearance adjustment
2
Refer to Chapter 2, Part A.
8 Manual transmission oil level check
1
1The manual transmission does not have a
dipstick. To check the oil level, raise the
vehicle and support it securely on axle stands,
making sure that the vehicle is level. On the
lower front side of the transmission housing,
you will see the filler/level plug. Unscrew and
remove it - an Allen key or bit will probably be
required (see illustration) .
2 With the plug removed, check the oil level.
To do this accurately, make up an oil level
check dipstick from a short length of welding
rod or similar material. Make a 90º bend in the
rod, then mark the downward leg in 5 mm
increments. The dipstick is then inserted
through the filler plug orifice so that the
unmarked leg rests flat on the plug orifice
threads, with the marked leg dipped in the oil.
Withdraw the dipstick and read off the level of
oil.
3 The oil level must be maintained between 0
and 5 mm below the lower edge of the
filler/level plug hole. Top up (if necessary),
using fresh transmission oil of the specified
type and using a syringe, or a plastic bottle
and tube. Refit and tighten the filler/level plug
to the specified torque on completion. 4
The need for regular topping-up can only
be due to a leak, which should be found and
rectified without delay.
5 Regular oil changing is not specified by the
manufacturer’s, but the oil can be drained, if
required, by removing the selector shaft cap
nut and locking assembly.
9 Idle speed and mixture check and adjustment
4
General
1Many of the engines fitted to Fiesta models
are equipped with fuel injection systems of
one sort or another which are entirely
controlled by the engine management system.
On most of these vehicles, it isn’t possible to
make any adjustments to the idle speed or the
mixture settings without specialist test
equipment of a type usually only found at a
Ford dealer or fuel injection specialist.
However, the very nature of these highly-
sophisticated systems means they don’t go
out of tune very often (if ever), so that it’s one
less maintenance operation to worry about.
2 On carburettor engines and 1.6 litre EFi fuel
injection engines, certain checks and
adjustments are necessary as part of the
service requirements, and these are described
below.
Idle speed and mixture check
and adjustment - carburettor
engines
Note: Later carburettors are fitted with
tamperproof mixture adjusting screws,
consisting of a hexagon-shaped socket with a
pin in the centre. Such screws require the use
of Ford service tool 23-032 to alter their
settings; if this tool (or a suitable equivalent) is
not available, the CO level will have to be
checked, and any necessary adjustment will
have to be made, by a Ford dealer.
3 Before carrying out the following checks
and adjustments, ensure that the spark plugs
are in good condition and correctly gapped
(Section 21). To carry out the checks/adjustments, an accurate tachometer
and an exhaust gas analyser (CO meter) will
be required.
4
Make sure that all electrical components
are switched off during the following
procedures.
5 Connect a tachometer to the engine in
accordance with its manufacturer’s
instructions, and insert the probe of an
exhaust gas analyser (CO meter) into the
exhaust tailpipe. As previously mentioned,
these items are essential in obtaining an
accurate setting. If they are not available, an
approximate check/adjustment can be made
as a temporary measure, providing they are
further checked out as soon as is possible
using a tachometer and a CO meter (or by a
Ford dealer).
6 Run the engine at a fast idle speed until it
reaches its normal operating temperature and
the radiator cooling fan cuts in. Turn the
engine off, then disconnect the radiator
cooling fan lead at the thermostatic switch
connector. Now connect a temporary wire to
the fan switch multi-plug, as shown (see
illustration) to enable the fan to operate
continuously during the following checks and
adjustments (if this is specified). Take care to
keep clear of the fan during the following
operations when working in the engine
compartment.
7 Where fitted, disconnect the throttle kicker
vacuum pipe, and plug the end. To identify
the throttle kicker unit, refer to Chapter 4A.
8 Check that the vehicle lighting and other
electrical loadings (apart from the radiator
cooling fan) are switched off, then restart the
engine. Increase the engine speed to 3000 rpm
for 30 seconds, and repeat this at three-minute
intervals during the check/adjustment
procedures. This will ensure that any excess
fuel is cleared from the inlet manifold.
9 Ensure that the throttle is fully released, allow
the meters to stabilise for a period of 5 to
30 seconds is normally sufficient, then check
the idle speed against that specified. If adjust-
ment is necessary, turn the idle speed
adjusting screw until the engine is idling at the
specified speed (see illustrations) . Any checks
and adjustments must be completed within
30 seconds of the meters stabilising.

lubricant, together with dirt and water entry,
resulting in rapid deterioration of the balljoints
or steering gear.
3Check the power-assisted steering fluid
hoses (where fitted) for chafing or
deterioration, and the pipe and hose unions
for fluid leaks. Also check for signs of fluid
leakage under pressure from the steering gear
rubber gaiters, which would indicate failed
fluid seals within the steering gear.
4 Grasp the roadwheel at the 12 o’clock and
6 o’clock positions, and try to rock it. Very
slight free play may be felt, but if the
movement is appreciable, further investigation
is necessary to determine the source.
Continue rocking the wheel while an assistant
depresses the footbrake. If the movement is
now eliminated or significantly reduced, it is
likely that the hub bearings are at fault. If the
free play is still evident with the footbrake
depressed, then there is wear in the
suspension joints or mountings.
5 Now grasp the wheel at the 9 o’clock and 3
o’clock positions, and try to rock it as before.
Any movement felt now may again be caused
by wear in the hub bearings or the steering
track rod balljoints. If the outer track rod end
balljoint is worn, the visual movement will be
obvious. If the inner joint is suspect, it can be
felt by placing a hand over the rack-and-
pinion rubber gaiter, and gripping the track
rod. If the wheel is now rocked, movement will
be felt at the inner joint if wear has taken
place.
6 Using a large screwdriver or flat bar, check
for wear in the suspension mounting bushes
by levering between the relevant suspension
component and its attachment point. Some
movement is to be expected, as the
mountings are made of rubber, but excessive
wear should be obvious. Also check the
condition of any visible rubber bushes,
looking for splits, cracks or contamination of
the rubber.
7 With the vehicle standing on its wheels,
have an assistant turn the steering wheel
back-and-forth, about an eighth of a turn each
way. There should be very little, if any, lost
movement between the steering wheel and
roadwheels. If this is not the case, closely
observe the joints and mountings previously described, but in addition, check the steering
column universal joints for wear, and also
check the rack-and-pinion steering gear itself.
Rear suspension check
8
Chock the front wheels then jack up the
rear of the car and support it on axle stands
(see “Jacking and Vehicle Support” ). Remove
the rear roadwheels.
9 Check the rear hub bearings for wear, using
the method described for the front hub
bearings (paragraph 4).
10 Using a large screwdriver or flat bar,
check for wear in the suspension mounting
bushes by levering between the relevant
suspension component and its attachment
point. Some movement is to be expected, as
the mountings are made of rubber, but
excessive wear should be obvious. Check the
condition of the shock absorbers and their
bushes/mountings. On Van models, check the
leaves of the leaf springs for signs of cracking,
distortion, or other damage.
Roadwheel check and balancing
11 Periodically remove the roadwheels, and
clean any dirt or mud from the inside and
outside surfaces. Examine the wheel rims for
signs of rusting, corrosion or other damage.
Light alloy wheels are easily damaged by
“kerbing” whilst parking, and similarly, steel
wheels may become dented or buckled.
Renewal of the wheel is very often the only
course of remedial action possible.
12 The balance of each wheel and tyre
assembly should be maintained, not only to
avoid excessive tyre wear, but also to avoid
wear in the steering and suspension
components. Wheel imbalance is normally
signified by vibration through the vehicle’s
bodyshell, although in many cases it is
particularly noticeable through the steering
wheel. Conversely, it should be noted that
wear or damage in suspension or steering
components may cause excessive tyre wear.
Out-of-round or out-of-true tyres, damaged
wheels and wheel bearing wear/
maladjustment also fall into this category.
Balancing will not usually cure vibration
caused by such wear.
13 Wheel balancing may be carried out with
the wheel either on or off the vehicle. If balanced on the vehicle, ensure that the
wheel-to-hub relationship is marked in some
way prior to subsequent wheel removal, so
that it may be refitted in its original position.
11 Driveshaft rubber gaiter and
CV joint check
1
1The driveshaft rubber gaiters are very
important, because they prevent dirt, water
and foreign material from entering and
damaging the constant velocity (CV) joints.
External contamination can cause the gaiter
material to deteriorate prematurely, so it’s a
good idea to wash the gaiters with soap and
water occasionally.
2 With the vehicle raised and securely
supported on axle stands, turn the steering
onto full-lock, then slowly rotate each front
wheel in turn. Inspect the condition of the
outer constant velocity (CV) joint rubber
gaiters, squeezing the gaiters to open out the
folds. Check for signs of cracking, splits, or
deterioration of the rubber, which may allow
the escape of grease, and lead to the ingress
of water and grit into the joint (see
illustration) . Also check the security and
condition of the retaining clips. Repeat these
checks on the inner CV joints. If any damage
or deterioration is found, the gaiters should be
renewed as described in Chapter 8.
3 At the same time, check the general
condition of the outer CV joints themselves,
by first holding the driveshaft and attempting
to rotate the wheels. Any appreciable
movement in the CV joint indicates wear in the
joint, wear in the driveshaft splines, or a loose
driveshaft retaining nut. Repeat this check on
the inner joints, by holding the inner joint yoke
and attempting to rotate the driveshaft.
12 Exhaust system check
1
1 With the engine cold (at least three hours
after the vehicle has been driven), check the
complete exhaust system, from its starting
1•16Every 10 000 miles or 12 months

point at the engine to the end of the tailpipe.
Ideally, this should be done on a hoist, where
unrestricted access is available; if a hoist is
not available, raise and support the vehicle on
axle stands.
2Check the pipes and connections for
evidence of leaks, severe corrosion, or
damage. Make sure that all brackets and
rubber mountings are in good condition, and
tight; if any of the mountings are to be
renewed, ensure that the replacements are of
the correct type (see illustration) . Leakage at
any of the joints or in other parts of the system
will usually show up as a black sooty stain in
the vicinity of the leak. Note: Exhaust sealants
should not be used on any part of the exhaust
system upstream of the catalytic converter -
even if the sealant does not contain additives
harmful to the converter, pieces of it may
break off and foul the element, causing local
overheating.
3 At the same time, inspect the underside of
the body for holes, corrosion, open seams,
etc, which may allow exhaust gases to enter
the passenger compartment. Seal all body
openings with silicone or body putty.
4 Rattles and other noises can often be
traced to the exhaust system, especially the
rubber mountings. Try to move the system,
silencer(s) and catalytic converter. If any
components can touch the body or
suspension parts, secure the exhaust system
with new mountings.
5 Check the running condition of the engine
by inspecting inside the end of the tailpipe;
the exhaust deposits here are an indication
of the engine’s state of tune. The inside of the
tailpipe should be dry, and should vary in
colour from dark grey to light grey/brown; if it
is black and sooty, or coated with white
deposits, the engine is in need of a thorough
fuel system inspection.
13 Underbody and fuel/brake line check
1
1With the vehicle raised and supported on
axle stands or over an inspection pit,
thoroughly inspect the underbody and wheel
arches for signs of damage and corrosion. In
particular, examine the bottom of the side
sills, and any concealed areas where mud can
collect. Where corrosion and rust is evident,
press and tap firmly on the panel with a
screwdriver, and check for any serious
corrosion which would necessitate repairs. If
the panel is not seriously corroded, clean
away the rust, and apply a new coating of
underseal. Refer to Chapter 11 for more
details of body repairs.
2 At the same time, inspect the PVC-coated
lower body panels for stone damage and
general condition.
3 Inspect all of the fuel and brake lines on the
underbody for damage, rust, corrosion and
leakage. Also make sure that they are correctly supported in their clips. Where
applicable, check the PVC coating on the
lines for damage.
14 Brake check
2
Note:
For detailed photographs of the brake
system, refer to Chapter 9.
1 The work described in this Section should
be carried out at the specified intervals, or
whenever a defect is suspected in the braking
system. Any of the following symptoms could
indicate a potential brake system defect:
a) The vehicle pulls to one side when the brake pedal is depressed.
b) The brakes make scraping or dragging
noises when applied.
c) Brake pedal travel is excessive.
d) The brake fluid requires repeated topping-
up.
2 A thorough inspection should be made to
confirm the thickness of the linings, as
follows.
Front brakes
3 Chock the rear wheels then jack up the
front of the car and support it on axle stands
(see “Jacking and Vehicle Support” ).
4 For better access to the brake calipers,
remove the wheels.
5 Look through the inspection window in the
caliper, and check that the thickness of the
friction lining material on each of the pads is
not less than the recommended minimum
thickness given in the Specifications. Note:
Bear in mind that the lining material is normally
bonded to a metal backing plate.
6 If it is difficult to determine the exact
thickness of the pad linings, or if you are at all
concerned about the condition of the pads,
then remove them from the calipers for further
inspection (refer to Chapter 9).
7 Check the remaining brake caliper in the
same way.
8 If any one of the brake pads has worn down to, or below, the specified limit,
all fourpads
must be renewed as a set.
9 Measure the thickness of the discs with a
micrometer, if available, to make sure that they
still have service life remaining. If any disc is
thinner than the specified minimum thickness,
renew it (refer to Chapter 9). In any case,
check the general condition of the discs. Look
for excessive scoring and discolouration
caused by overheating. If these conditions
exist, remove the relevant disc and have it
resurfaced or renewed (refer to Chapter 9).
10 Before refitting the wheels and lowering
the car, check all brake lines and hoses (refer
to Chapter 9). In particular, check the flexible
hoses in the vicinity of the calipers, where
they are subjected to most movement. Bend
them between the fingers (but do not actually
bend them double, or the casing may be
damaged) and check that this does not reveal
previously-hidden cracks, cuts or splits.
Rear brakes
11 Chock the front wheels then jack up the
rear of the car and support it on axle stands
(see “Jacking and Vehicle Support” ).
12 For better access, remove the rear
wheels.
13 To check the brake shoe lining thickness
without removing the brake drums, prise the
rubber plugs from the backplates, and use an
electric torch and mirror to inspect the linings
of the leading brake shoes. Check that the
thickness of the lining material on the brake
shoes is not less than the recommendation
given in the Specifications.
14 If 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 Chap-
ter 9).
15 With 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.
16 Before 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 also requires periodic adjustment,
and if its travel seems excessive, refer to
Section 27.
15 Roadwheel nut tightness check
1
1Apply the handbrake.
2 Remove the wheel covers, using the flat
end of the wheelbrace supplied in the tool kit
(on some models it will be necessary to
unscrew the retaining bolts with a special
key).
Every 10 000 miles or 12 months1•17
12.2 Ensure that the exhaust system
rubber mountings replacements are of the correct type - their colour is a good guide. Those nearest to the catalytic converterare more heat-resistant than the others

3Check that the roadwheel nuts are tightened
to the specified torque wrench setting.
4 Refit the wheel covers.
16 Door, tailgate and bonnet
check and lubrication
1
1Check that the doors and tailgate/boot lid
close securely. Check that the bonnet safety
catch operates correctly. Check the operation
of the door check straps.
2 Lubricate the hinges, door check straps,
the striker plates and the bonnet catch
sparingly with a little oil or grease.
17 Seat belt check
1
1 Check the seat belts for satisfactory
operation and condition. Inspect the webbing
for fraying and cuts. Check that they retract
smoothly and without binding into their reels.
2 Check that the seat belt mounting bolts are
tight, and if necessary tighten them to the
specified torque wrench settings as given in
Chapter 11.
18 Bodywork, paint and exterior trim check

1The best time to carry out this check is after
the car has been washed so that any surface
blemish or scratch will be clearly evident and
not hidden by a film of dirt.
2 Starting at one front corner check the
paintwork all around the car, looking for minor
scratches or more serious dents. Check all
the trim and make sure that it is securely
attached over its entire length.
3 Check the security of all door locks, door
mirrors, badges, bumpers, front grille and
wheel trim. Anything found loose, or in need of
further attention should be done with reference
to the relevant Chapters of this manual.
4 Rectify any problems noticed with the
paintwork or body panels as described in
Chapter 11.
19 Road test
1
Check the operation and
performance of the braking
system
1 Make sure that the vehicle does not pull to
one side when braking, and that the wheels
do not lock prematurely when braking hard.
2 Check that there is no vibration through the
steering when braking. 3
Check that the handbrake operates
correctly, without excessive movement of the
lever, and that it holds the vehicle stationary
on a slope.
4 Test the operation of the brake servo unit
as follows. With the engine switched off,
depress the footbrake four or five times to
exhaust the vacuum, then hold the pedal
depressed. Start the engine, and 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 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
firmer.
Steering and suspension
5 Check for any abnormalities in the steering,
suspension, handling or road “feel”.
6 Drive the vehicle, and check that there are
no unusual vibrations or noises.
7 Check that the steering feels positive, with
no excessive sloppiness or roughness, and
check for any suspension noises when
cornering and driving over bumps.
Drivetrain
8 Check the performance of the engine,
transmission and driveshafts.
9 Check that the engine starts correctly, both
when cold and when hot.
10 Listen for any unusual noises from the
engine and transmission.
11 Make sure that the engine runs smoothly
when idling, and that there is no hesitation
when accelerating.
12 On 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”.
13 On automatic transmission models, make
sure that the drive seems smooth without
jerks or engine speed “flare-ups”. 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.
14 Listen 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
15 Check 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.
16 Inspect both ends of the clutch inner
cable, both at the transmission end and inside
the car, for signs of wear and fraying.
Instruments and electrical
equipment
17 Check the operation of all instruments
and electrical equipment.
18 Make sure that all instruments read
correctly, and switch on all electrical equipment
in turn, to check that it functions properly.
20 Automatic transmission fluid level check
1
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.
2 The 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 60
to 70ºC, 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.
3 Park 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
positions three times, beginning and ending in
“P”.
4 Allow the engine to idle for one minute, then
(with the engine still idling) remove the
dipstick from its tube. Note the condition and
colour of the fluid on the dipstick.
5 Wipe the fluid from the dipstick with a clean
rag, and re-insert it into the filler tube until the
cap seats.
6 Pull 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. It is important not to introduce
dirt into the transmission when topping-up.
7 Add the fluid a little at a time, and keep
checking the level as previously described
until it is correct. The difference between the
“MIN” and “MAX” marks on the dipstick is
approximately 0.4 litres.
8 The need for regular topping-up of the
transmission fluid indicates a leak, which
should be found and rectified without delay.
9 The condition of the fluid should also be
checked along with the level. If the fluid on 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.

21 Spark plug renewal and HTcomponent check
1
Note: Spark plug renewal at this service
interval is only necessary on the HCS, CVH
and PTE engines. On Zetec engines, the
recommended interval for spark plug renewal
is every 30 000 miles or three years.
Spark plug check and renewal
1 It is vital for the correct running, full
performance and proper economy of the engine
that the spark plugs perform with maximum
efficiency. The most important factor in ensuring
this is that the plugs fitted are appropriate for the
engine. The suitable type is given in the
Specifications Section at the beginning of this
Chapter, on the Vehicle Emissions Control
Information (VECI) label located on the
underside of the bonnet (only on models sold in
some areas) or in the vehicle’s Owner’s
Handbook. If the correct type is used and the
engine is in good condition, the spark plugs
should not need attention between scheduled
renewal intervals. Spark plug cleaning is rarely
necessary, and should not be attempted unless
specialised equipment is available, as damage
can easily be caused to the firing ends.
2 Spark plug removal and refitting requires a
spark plug socket, with an extension which can
be turned by a ratchet handle or similar. This
socket is lined with a rubber sleeve, to protect
the porcelain insulator of the spark plug, and to
hold the plug while you insert it into the spark
plug hole. You will also need a set of feeler
gauges, to check the spark plug electrode gap,
and a torque wrench to tighten the new plugs
to the specified torque (see illustration).
3 To remove the spark plugs, first open the
bonnet; the plugs are easily reached at the
top of the engine. Note how the spark plug
(HT) leads are routed and secured by clips,
and on some engines, how they’re positioned
along the channel in the cylinder head cover.
To prevent the possibility of mixing up spark
plug (HT) leads, it is a good idea to try to work
on one spark plug at a time.
4 If the marks on the original-equipment spark
plug (HT) leads cannot be seen, mark the leads
1 to 4, to correspond to the cylinder the lead
serves (No 1 cylinder is at the timing belt/chain
end of the engine). Pull the leads from the plugs
by gripping the rubber boot, not the lead,
otherwise the lead connection may be fractured.
5 It is advisable to soak up any liquid in the
spark plug recesses with a rag, and to remove
any dirt from them using a clean brush,
vacuum cleaner or compressed air before
removing the plugs, to prevent any dirt or
water from dropping into the cylinders. Warning: Wear eye protection
when using compressed air!
6 Unscrew the spark plugs, ensuring that the
socket is kept in alignment with each plug - if
the socket is forcibly moved to either side, the
porcelain top of the plug may be broken off. If
any undue difficulty is encountered when
unscrewing any of the spark plugs, carefully
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.
7 As each plug is removed, examine it as
follows - this will give a good indication of the
condition of the engine. If 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.
8 If 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.
9 If the insulator nose of the spark plug is clean and white, with no deposits, this is
indicative of a weak mixture.
10
If 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.
11 The 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.
12 The spark plug gap is correct when the
correct-size feeler gauge or wire gauge is a
firm sliding fit between the electrodes (see
illustrations) .
13 To adjust the electrode gap, bend open, or
close up, 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. Special spark plug gap adjusting
tools are available from motor accessory shops,
or from certain spark plug manufacturers.
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.
15 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.
16 When each spark plug is started correctly
on its threads, screw it down until it just seats
lightly, then tighten it to the specified torque
wrench setting. 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 than
1/4 of a turn (CVH and PTE engines) or 1/16 of a
turn (HCS and Zetec engines) after it seats. HCS
and Zetec engines are fitted with taper-seat
spark plugs, identifiable by not having a sealing
washer, and these in particular should NEVER
be overtightened - their tapered seats mean
they are almost impossible to remove if abused.
17 Reconnect 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, distributor
cap and rotor arm check
18 The 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.
19
The 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.
20 Check 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
eroded 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.
21 Using a clean rag, wipe the entire length
of the lead to remove built-up dirt and grease. Once the lead is clean, check for burns,
cracks and other damage. Do not bend the
lead sharply, because the conductor might
break.
22 Disconnect the lead from the ignition coil
by pressing together the plastic retaining
catches (where fitted) and pulling the end
fitting off the coil terminal. Check for corrosion
and for a tight fit. If a meter with the correct
measuring range is available, measure the
resistance of the disconnected lead from its
coil connector to its spark plug connector. If
the resistance recorded for any of the leads
exceeds the value specified, all the leads
should be renewed as a set. Refit the lead to
the coil, noting that each coil terminal is
marked with its respective cylinder number,
so that there is no risk of mixing up the leads
and upsetting the firing order.
23 Inspect the remaining spark plug (HT)
leads, ensuring that each is securely fastened
at the distributor cap or ignition coil and spark
plug when the check is complete. If any sign
of arcing, severe connector corrosion, burns,
cracks or other damage is noticed, obtain new
spark plug (HT) leads, renewing them as a set.
If new spark plug leads are to be fitted,
remove and refit them one at a time, to avoid
mix-ups in the firing order. 24
On models with distributor ignition
systems, refer to Chapter 5B and remove the
distributor cap then thoroughly clean it inside
and out with a dry lint-free rag.
25 Examine the HT lead segments inside the
cap. If they appear badly burned or pitted
renew the cap. Also check the carbon brush
in the centre of the cap, ensuring that it is free
to move and stands proud of its holder. Make
sure that there are no sign of cracks or black
“tracking” lines running down the inside of the
cap, which will also mean renewal if evident.
26 Inspect the rotor arm checking it for
security and also for signs of deterioration as
described above.
27 Refit the cap as described in Chapter 5B
on completion.
22 Idle speed control valve cleaning and maintenance
1
Note: The idle speed control valve may be
mounted on the air cleaner, on the engine
compartment bulkhead, or on the side of the inlet
manifold according to valve make and year of
manufacture. Valves manufactured by Weber are
mounted on the air cleaner and only these valves
require the periodic maintenance described
below. Bulkhead and inlet manifold mounted
valves are manufactured by Hitachi and are
maintenance free. Refer to the warning note in
Section 1 of Chapter 4C before proceeding.
1 Remove the valve as described in Chap-
ter 4C, Section 14.
2 Immerse the valve head in a suitable
container filled with clean petrol, and allow it
to soak for approximately three minutes.
3 Clean the valve bore, slots and piston with
petrol, using a suitable lint-free cloth, then
gently move the piston up and down in its
bore using a small screwdriver (see
illustration) . Ensure that no cloth particles
enter the bore, and do not use the slots to
move the piston.
4 Rinse the valve again with clean petrol, then
dry it using an air line (or other source of
compressed air).
Warning: Wear eye protection
when using compressed air!
5 Clean the mating faces of the valve and the
air filter housing then refit as described in
Chapter 4C, Section 14.

It’s often difficult to insert spark plugs
into their holes without cross-threading
them. To avoid this possibility, fit a
short piece of rubber hose over the end
of the spark 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.
If new spark plug leads are tobe fitted, remove the leads
one at a time and fit each
new lead in exactly the same
position as the old one.
