General information
This Chapter is designed to help the home
mechanic maintain his/her vehicle for safety,
economy, long life and peak performance.
The 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
can be inspected at the same time as thesuspension and steering components.
The first step in 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.
Intensive maintenance
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.
It is possible that there will be 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.
If engine wear is suspected, a compression
test 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 greatlyimprove the performance of the engine, and
may prove a waste of time and money, unless
extensive overhaul work is carried out first.
The following series of operations are those
most often required to improve the
performance of a generally poor-running
engine:
Primary operations
a)Clean, inspect and test the battery
b)Check all the engine-related fluids
c)Check the condition and tension of the
auxiliary drivebelt
d)Renew the spark plugs
e)Inspect the distributor cap and HT leads -
as applicable
f)Check the condition of the air cleaner
filter element, and renew if necessary
g)Renew the fuel filter
h)Check the condition of all hoses, and
check for fluid leaks
i)Check the idle speed and mixture settings
- as applicable
If the above operations do not prove fully
effective, carry out the following secondary
operations:
Secondary operations
a)Check the charging system
b)Check the ignition system
c)Check the fuel system
d)Renew the distributor cap and rotor arm -
as applicable
f)Renew the ignition HT leads - as
applicable

1Frequent oil and filter changes are the most
important preventative maintenance
procedures which can be undertaken by the
DIY owner. As engine oil ages, it becomes
diluted and contaminated, which leads to
premature engine wear.
2Before starting this procedure, gather
together all the necessary tools and materials.
Also make sure that you have plenty of clean
rags and newspapers handy, to mop up any
spills. Ideally, the engine oil should be warm,
as it will drain better, and more built-upsludge will be removed with it. Take care,
however, not to touch the exhaust or any
other hot parts of the engine when working
under the vehicle. 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. Access to the underside of the
vehicle will be greatly improved if it can be
raised on a lift, driven onto ramps, or jacked
up and supported on axle stands (see
“Jacking and vehicle support”). Whichever
method is chosen, make sure that the vehicle
remains level, or if it is at an angle, so that the
drain plug is at the lowest point (see
illustration).

Every 250 miles (400 km) or weekly
Every 6000 miles (10 000 km) or 6 months

3Slacken the drain plug about half a turn.
Position the draining container under the drain
plug, then remove the plug completely. If
possible, try to keep the plug pressed into the
sump while unscrewing it by hand the last
couple of turns. As the plug releases from the
threads, move it away sharply so the stream
of oil issuing from the sump runs into the
container, not up your sleeve! Recover the
sealing washer from the drain plug.
4Allow some time for the old oil to drain,
noting that it may be necessary to reposition
the container as the oil flow slows to a trickle.
5After all the oil has drained, wipe off the
drain plug with a clean rag. Check the sealing
washer for condition, and renew it if
necessary. Clean the area around the drain
plug opening, and refit the plug. Tighten the
plug to the specified torque.
6Move the container into position under the
oil filter.
7Using an oil filter removal tool if necessary,
slacken the filter initially, then unscrew it by
hand the rest of the way (see illustration).
Empty the oil from the old filter into the
container, and discard the filter.
8Use a clean rag to remove all oil, dirt and
sludge from the filter sealing area on the
engine. Check the old filter to make sure that
the rubber sealing ring hasn’t stuck to the
engine. If it has, carefully remove it.
9Apply a light coating of clean engine oil to
the sealing ring on the new filter, then screw it
into position on the engine. Tighten the filter
firmly by hand only - do notuse any tools.
Wipe clean the filter and sump drain plug.10Remove the old oil and all tools from
under the car, then lower the car to the
ground (if applicable).
11Remove the oil filler cap and withdraw the
dipstick. Fill the engine, using the correct
grade and type of oil (see “Lubricants and
fluids”). An oil can spout or funnel may help to
reduce spillage. Pour in half the specified
quantity of oil first, then wait a few minutes for
the oil to fall to the sump. Continue adding oil
a small quantity at a time until the level is up to
the lower mark on the dipstick. Finally, bring
the level up to the upper mark on the dipstick.
Insert the dipstick, and refit the filler cap.
12Start the engine and run it for a few
minutes; check for leaks around the oil filter
seal and the sump drain plug. Note that there
may be a delay of a few seconds before the oil
pressure warning light goes out when the
engine is first started, as the oil circulates
through the engine oil galleries and the new oil
filter, before the pressure builds up.
13Switch off the engine, and wait a few
minutes for the oil to settle in the sump once
more. With the new oil circulated and the filter
completely full, recheck the level on the
dipstick, and add more oil as necessary.
14Dispose of the used engine oil safely, with
reference to “General repair procedures”in
the Reference section of this manual.
1Firmly apply the handbrake, then jack up
the front and rear of the car and support it
securely on axle stands (see “Jacking and
vehicle support”).
2For a quick check, the front brake disc pads
can be inspected without removing the front
wheels by inserting a mirror between each
caliper and roadwheel(see illustration).If any
one pad is worn down to the minimum
specified thickness, all four pads (on both
front wheels) must be renewed.
3It is necessary to remove the rear wheels in
order to inspect the rear disc pads. The pads
can be viewed through the top of the caliper
after removing the blanking spring clip(see
illustration).If any one pad is worn down to
the minimum specified, all four pads (on both
rear wheels) must be renewed.4For a comprehensive check, the brake disc
pads should be removed and cleaned. The
operation of the caliper can then also be
checked, and the condition of the brake discs
can be fully examined on both sides. Refer to
Chapter 10 for further information.
5On rear drum brake models, the brake shoe
friction material can be inspected for wear
without removing the roadwheels. Working
beneath the vehicle, prise the plug from the
brake backplate, and using an inspection
lamp or torch, check that the friction material
thickness is not less than the minimum given
in the Specifications(see illustration).If any
one of the shoes has worn below the
specified limit, the shoes must be renewed as
an axle set (4 shoes).
6At the same interval, check the function of the
brake fluid level warning light. Chock the wheels,
release the handbrake and switch on the
ignition. Unscrew and raise the brake fluid
reservoir cap whilst an assistant observes the
warning light: it should come on as the level
sensor is withdrawn from the fluid. Refit the cap.
7On completion, refit the wheels and lower
the car to the ground.
1Visually inspect the engine joint faces,
gaskets and seals for any signs of water or oil
leaks. Pay particular attention to the areas
around the rocker cover, cylinder head, oil
filter and sump joint faces. Bear in mind that
over a period of time some very slight
seepage from these areas is to be expected
but what you are really looking for is any
indication of a serious leak. Should a leak be
found, renew the offending gasket or oil seal
by referring to the appropriate Chapter(s) in
this manual.
2Similarly, check the transmission for oil
leaks, and investigate and rectify and
problems found.
3Check the security and condition of all the
engine related pipes and hoses. Ensure that
all cable-ties or securing clips are in place and
in good condition. Clips which are broken or
missing can lead to chafing of the hoses,
pipes or wiring which could cause more
serious problems in the future.

4Carefully check the condition of all coolant,
fuel, power steering and brake hoses. Renew
any hose which is cracked, swollen or
deteriorated. Cracks will show up better if the
hose is squeezed. Pay close attention to the
hose clips that secure the hoses to the system
components. Hose clips can pinch and
puncture hoses, resulting in leaks. If wire type
hose clips are used, it may be a good idea to
replace them with screw-type clips.
5With the vehicle raised, inspect the fuel
tank and filler neck for punctures, cracks and
other damage. The connection between the
filler neck and tank is especially critical.
Sometimes a rubber filler neck or connecting
hose will leak due to loose retaining clamps or
deteriorated rubber.
6Similarly, inspect all brake hoses and metal
pipes. If any damage or deterioration is
discovered, do not drive the vehicle until the
necessary repair work has been carried out.
Renew any damaged sections of hose or pipe.
7Carefully check all rubber hoses and metal
fuel lines leading away from the petrol tank.
Check for loose connections, deteriorated
hoses, crimped lines and other damage. Pay
particular attention to the vent pipes and
hoses which often loop up around the filler
neck and can become blocked or crimped.
Follow the lines to the front of the vehicle
carefully inspecting them all the way. Renew
damaged sections as necessary.
8From within the engine compartment,
check the security of all fuel hose attachments
and pipe unions, and inspect the fuel hoses
and vacuum hoses for kinks, chafing and
deterioration.
9Where applicable, check the condition of
the oil cooler hoses and pipes.
10Check the condition of all exposed wiring
harnesses.
1Periodically check the belts for fraying or
other damage. If evident, renew the belt.
2If the belts become dirty, wipe them with a
damp cloth using a little detergent only.
3Check the tightness of the anchor bolts and
if they are ever disconnected, make quite sure
that the original sequence of fitting of
washers, bushes and anchor plates is
retained.
With the vehicle raised on a hoist or
supported on axle stands, check the exhaust
system for signs of leaks, corrosion or
damage and check the rubber mountings for
condition and security. Where damage or
corrosion are evident, renew the system
complete or in sections, as applicable, using
the information given in Chapter 4.With the wheels on the ground, slacken each
wheel nut by a quarter turn, then retighten it
immediately to the specified torque.
Remove and clean the oil filler cap of any
sludge build-up using paraffin.
Inspect the vent hose for blockage or
damage. A blocked hose can cause a build-
up of crankcase pressure, which in turn can
cause oil leaks.
Ford VV carburettor
1Ensure that the air cleaner is correctly fitted,
and that all vacuum hoses and pipes are
securely connected and free from restrictions,
then run the engine until it is at normal
operating temperature.
2Stop the engine, and connect a tachometer
and an exhaust gas analyser in accordance
with the manufacturer’s instructions.
3Start the engine and run it at 3000 rpm for
30 seconds, ensuring that all electrical loads
are switched off (headlamps, heater blower
etc), then allow the engine to idle and check
the idle speed and CO content. Note that the
CO reading will initially rise, then fall and finally
stabilise after between 5 and 25 seconds.4If necessary, adjust the idle speed screw to
give the specified idle speed (see
illustration).
5Checking and adjustment should be
completed within 30 seconds of the meter
readings stabilising. If this has not been
possible, repeat paragraphs 3 and 4, ignoring
the reference to starting the engine.
Weber 2V carburettor
Models without stepper motor
6Proceed as described for the Ford VV
carburettor but note the following:
7It is permissible to loosen the air cleaner
securing screws to allow easier access to the
carburettor adjustment screws but ensure
that all vacuum hoses and pipes are securely
connected. For adjustment screw location
(see illustrations).
Models with stepper motor (ESC II
system)
8The idle speed is controlled by the ESC II
module via the stepper motor. The only idle
speed adjustment possible is provided by the
“idle speed adjustment” wire, which can be
earthed to raise the idle speed by 75 rpm. No
other method of idle speed adjustment should
be attempted. If the idle speed is incorrect,
the problem should be referred to a Ford
dealer, as the problem probably lies in the
ESC II module for which special diagnostic
equipment is required.

Caution: Refer to the
precautions in Section 1,
Chapter 4, Part A or B (as
applicable), before proceeding.
Before carrying out any carburettor
adjustments, ensure that the ignition
timing and spark plug gaps are set as
specified. To carry out the adjustments an
accurate tachometer and an exhaust gas
analyser (CO meter) will be required.

3Wipe clean around the filler/level plug.
Unscrew the plug and remove it(see
illustration).
4Using a suitably marked piece of bent wire
as a dipstick, check that the oil level is as
shown in the table at the top of this page,
according to gearbox type.
5Top-up the level if necessary, using clean
oil of the specified type. Do not overfill, as this
can lead to leakage and difficult gear
changing. Allow excess oil to drip out of the
filler/level hole if necessary. Refit and tighten
the filler/level plug on completion.
6The frequent need for topping-up can only
be due to leaks, which should be rectified.
The most likely sources of leaks are the rear
extension housing and input shaft oil seals.
7No periodic oil changing is specified, and
no drain plug is fitted.
1Work around the vehicle, and lubricate the
bonnet, door and tailgate hinges with a light
machine oil.
2Lightly lubricate the bonnet release
mechanism and exposed sections of inner
cable with a smear of grease.
3Check the security and operation of all
hinges, latches and locks, adjusting them
where required. Where applicable, check the
operation of the central locking system.
4Check the condition and operation of the
tailgate struts, renewing them if either is
leaking or is no longer able to support the
tailgate securely when raised.
1The correct functioning of the spark plugs is
vital for the correct running and efficiency of
the engine. It is essential that the plugs fitted
are appropriate for the engine.
2Make sure that the ignition is switched off
before inspecting the HT leads to see if they
carry their cylinder numbers. Note that the
position of No 1 cylinder HT lead in the
distributor cap is marked with either a pip, or
a number “1 “.3Where necessary, for improved access
remove the air cleaner and/or the inlet hose.
4Disconnect the leads from the plugs by
pulling on the connectors, not the leads.
5On 2.0 litre DOHC carburettor models, the
location of the spark plugs and the close
proximity of the carburettor makes spark plug
access difficult, particularly when removing
the plugs from cylinders 2 and 3. It is
suggested that a 3/8 inch ratchet drive spark
plug socket with rubber insert and long
extension bar is used, possibly in conjunction
with a universal joint adapter. It is also
advisable to disconnect No 3 cylinder HT lead
from the distributor first, to allow some slack
for disconnection at the spark plug.
6Clean the area around each spark plug
using a small brush, then using a plug
spanner (preferably with a rubber insert),
unscrew and remove the plugs(see
illustration).Cover the spark plug holes with
a clean rag to prevent the ingress of any
foreign matter.
7Before fitting new spark plugs, check that
the threaded connector sleeves are tight. As
the plugs incorporate taper seats, make sure
that the threads and seats are clean.8On DOHC models before refitting the spark
plugs, coat their threads with suitable anti-
seize compound, taking care not to
contaminate the electrodes.
9Screw in the spark plugs by hand, then
tighten them to the specified torque. Do not
exceed the torque figure.
10Push the HT leads firmly onto the spark
plugs, and where applicable refit the air
cleaner and/or inlet hose.
1Refer to the Specifications at the beginning
of this Chapter and check the tension of each
drivebelt at the point stated. Check the full
length of each drivebelt for cracks and
deterioration. It will be necessary to turn the
engine in order to check that portion of the
drivebelt in contact with the pulleys. Renew or
tension each belt as necessary as follows,
according to model type:
SOHC models
2Note that two drivebelts are fitted to models
equipped with power steering and both
should be renewed if either one is
unserviceable. Where fitted, the air
conditioning compressor is driven by a
separate belt.
3Disconnect the battery negative lead.
4Where applicable, remove the air
conditioning compressor drivebelt.
5Loosen the alternator mounting and
adjustment nuts and bolts, and pivot the
alternator towards the cylinder block.
6Slip the drivebelt(s) from the alternator,
water pump, crankshaft and (where
applicable) the power steering pump pulleys.
7Fit the new drivebelt(s) over the pulleys,
then lever the alternator away from the
cylinder block until the specified belt tension
is achieved. Lever the alternator using a
wooden or plastic lever at the pulley end to
prevent damage and straining the brackets. It
is helpful to partially tighten the adjustment
link bolt before tensioning the drivebelt(s).

8Tighten the alternator mounting and
adjustment nuts and bolts in the order shown
(see illustration).
9Where applicable, refit and tension the air
conditioning compressor drivebelt.
10Reconnect the battery negative lead.
11Drivebelt tension should be rechecked
and if necessary adjusted after the engine has
been run for a minimum of ten minutes.
DOHC models
12Three different types of drivebelt
arrangement are used, depending on model
(see illustrations).On models without powersteering, the drivebelt is tensioned by moving
the alternator. On models with power steering,
the power steering pump is also driven by the
coolant pump/alternator drivebelt and an
automatic belt tensioner is fitted (see
illustration).On models with air conditioning,
the drivebelt drives the alternator, coolant
pump, power steering pump and air
conditioning compressor, and an automatic
belt tensioner is fitted.
13On models without power steering, loosen
the alternator mounting and adjustment bolts,
and pivot the alternator towards the cylinder
block. Slip the drivebelt from the pulleys.
14On models with power steering, the
automatic tensioner can be released using a
17 mm socket and a wrench on the boss in
the centre of the pulley. Lever the tensioner
assembly clockwise, slide the belt from the
pulleys, then slowly release the tensioner.
15To fit a new belt on models without
power steering, slide the belt over the pulleys,
then lever the alternator away from the
cylinder block until the correct belt tension is
achieved. Lever the alternator using a plastic
or wooden lever at the pulley end to prevent
damage. It is helpful to partially tighten the
adjustment link bolt before tensioning the
drivebelt. When the correct tension is
achieved, tighten all the bolts.
16To fit a new belt on models with power
steering, lever the tensioner clockwise as
during removal, then slide the belt over the
pulleys, and slowly release the tensioner.
1The battery fitted as original equipment is
“maintenance-free”, and requires nomaintenance apart from having the case kept
clean, and the terminals clean and tight.
2To clean the battery terminals disconnect
them, after having first removed the cover
(later models) - negative earth first. Use a wire
brush or abrasive paper to clean the
terminals. Bad corrosion should be treated
with a solution of bicarbonate of soda, applied
with an old toothbrush. Do not let this solution
get inside the battery.
3Coat the battery terminals with petroleum
jelly or a proprietary anti-corrosive compound
before reconnecting them. Reconnect and
tighten the positive (live) lead first, followed by
the negative (earth) lead. Do not overtighten.
4Keep the top of the battery clean and dry.
Inspect the battery tray for corrosion, and
make good as necessary.
SOHC engines
1The valve clearances must be checked with
the engine cold. On carburettor models
remove the air cleaner.
2Disconnect the HT leads from the spark
plugs and release them from the clips on the
camshaft cover.
3On fuel injection models, unbolt and
remove the bracing strut securing the inlet
manifold to the right-hand side of the cylinder
head.
4Where applicable, unclip any hoses and
wires from the camshaft cover, then unscrew
the securing bolts and remove the camshaft
cover and gaskets. Take care not to lose the
spacer plates which fit under the bolt heads,
where applicable.

Caution: Before carrying out
any work on the vehicle battery,
read through the precautions
given in “Safety first!” at the
beginning of this manual.
It will be easier to turn the
engine by hand if the spark
plugs are removed but take
care not to allow dirt to enter
the spark plug holes.
