The maintenance intervals in this manual
are provided with the assumption that you will
be carrying out the work yourself. These are
the minimum maintenance intervals
recommended by the manufacturer for
vehicles driven daily. If you wish to keep your
vehicle in peak condition at all times, you maywish to perform some of these procedures
more often. We encourage frequent
maintenance, because it enhances the
efficiency, performance and resale value of
your vehicle.
If the vehicle is driven in dusty areas, used
to tow a trailer, or driven frequently at slowspeeds (idling in traffic) or on short journeys,
more frequent maintenance intervals are
recommended.
When the vehicle is new, it should be
serviced by a factory-authorised dealer
service department, in order to preserve the
factory warranty.

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).

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.

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.

13Reconnect the battery negative lead.
2.0 litre DOHC models
14Disconnect the battery negative lead.
15Disconnect the wiring plug from the idle
speed control valve at the front of the plenum
chamber.
16Loosen the clamp, and detach the air inlet
hose from the air inlet tubing.
17Unscrew the securing nut, and release the
air inlet tube from the bracket on the engine
compartment front panel (see illustration).
18Release the air cleaner lid securing clips,
then lift away the air inlet tube, plenum
chamber and air cleaner lid as an assembly,
disconnecting the breather hose from the air
inlet tube.
19Lift out the air cleaner element (see
illustration), then wipe the inside of the air
cleaner lid and casing clean.
20Fit the new element with the sealing lip
uppermost.
21Further refitting is a reversal of removal.
1Before disturbing any part of the ignition
system, disconnect the battery negative lead.
2Identify and clearly mark all HT leads before
disconnecting them from the spark plugs.
3Refer to the appropriate Section in Chapter
5 and, where applicable, remove the
distributor cap and rotor arm.
4Clean the HT leads and distributor cap with
a dry cloth. Scrape any corrosion or otherdeposits from the connectors and terminals.
Also clean the coil tower.
5Renew the HT leads if they are cracked,
burnt or otherwise damaged. If a multi-meter
is available, measure the resistance of the
leads. The desired value is given in the
Specifications of Chapter 5.
6Renew the distributor cap if it is cracked or
badly burnt inside, or if there is evidence of
“tracking” (black lines marking the path of HT
leakage). If there is a carbon brush at the
centre of the cap, make sure that it moves
freely, and is not excessively worn (see
illustration).
7Clean the metal track of the rotor arm with
fine abrasive paper. Renew the arm if it is
cracked or badly burnt.
8Refit the rotor arm and distributor cap.
9Reconnect the HT leads to the spark plugs
and coil.
10Reconnect the battery and run the engine.
Note: A brake band torque wrench - Ford tool
No 17-005, or a conventional torque wrench
and a splined socket of suitable size to fit the
square section head of the adjuster screw(s)
will be required for this operation.
1For improved access, apply the handbrake,
then jack up the front of the vehicle and
support on axle stands (see “Jacking and
vehicle support”).2The brake band adjuster screw(s) is/are
situated on the left-hand side of the
transmission housing, forward of the
kickdown lever. Note that the C3 type
transmission has a single adjuster screw for
adjustment of the front brake band, whereas
the A4LD type transmission has two adjuster
screws for adjustment of the front and
intermediate brake bands(see illustration).
3Disconnect the kickdown cable from the
kickdown lever on the transmission housing.
4Loosen the locknut on the front brake band
adjuster screw, and back off the adjuster
screw several turns.
5Using the Ford special tool or a suitable
equivalent, tighten the adjuster screw to the
specified torque, then back off the screw two
complete turns, and tighten the locknut.
Ensure that the adjuster screw does not turn
as the locknut is tightened.
6Repeat the procedure given in paragraphs
4 and 5 for the remaining adjuster screw on
A4LD type transmissions, but on all models
where the part number on the transmission
identification tag starts with “88”(see
illustration)and additionally on all 1.8 CVH
engine models, the adjuster screw should be
backed off two and a half turns after
tightening to the specified torque. On all other
models, the adjuster screw should be backed
off two turns.
7Reconnect the kickdown cable, and lower
the vehicle to the ground on completion.
2.0 litre SOHC fuel injection
models
1The fuel filter is located on the left-hand
side of the engine compartment(see
illustration).
2Disconnect the battery negative lead.
3Position a suitable container beneath the
filter, then slowly loosen the fuel inlet union to
relieve the pressure in the fuel lines.
4Disconnect the fuel inlet and outlet unions.
Be prepared for petrol spillage. If necessary,
identify the fuel line unions for use when
refitting.
5Loosen the filter clamp screw, and
withdraw the filter from the clamp. Drain the
petrol from the filter into the container.
Dispose of the filter carefully.
