Environmental Protection Precautions
It is illegal to pour used oil on to the ground, down
sewers or drains, or into water courses.
Burning of used engine oil in small space heaters or
boilers should only be considered for units of
approved design and in compliance with the
equipment manufacturer's recommendations. The
heating system must meet the regulatory standards
of HMIP for small burners of less than 0.4 MW. If in
doubt check with the appropriate local authority and/
or manufacturer of the approved appliance.
Dispose of used oil and filters through authorised
waste disposal contractors and licensed waste
disposal sites, or through the waste oil reclamation
trade. If in doubt, contact the Local Authority for
advice on disposal facilities.
Safety instructions
Whenever possible, use a lift or pit when working
beneath vehicle, in preference to jacking. Chock
wheels as well as applying parking brake.
Jacking
Always use the recommended jacking points. The
recommended jacking points are shown in
theLIFTING AND TOWING sub-section of the
INFORMATION section.
Always ensure that any lifting apparatus has
sufficient load capacity for the weight to be lifted.
Ensure the vehicle is standing on level ground prior
to lifting or jacking.
Apply the handbrake and chock the wheels.
WARNING: Do not work on or under a vehicle
supported only by a jack. Always support the
vehicle on safety stands.
Do not leave tools, lifting equipment, spilt oil, etc.,
around or on the work bench area. Always keep a
clean and tidy work area.
Brake shoes and pads
Always fit the correct grade and specification of
brake linings. When renewing brake pads and brake
shoes always replace as complete axle sets only.

Brake hydraulics
Observe the following recommendations when
working on the brake system:
lAlways use two spanners when loosening or
tightening brake pipe or hose connections.
lEnsure that hoses run in a natural curve and are
not kinked or twisted.
lFit brake pipes securely in their retaining clips
and ensure that the pipe run cannot contact a
potential chafing point.
lContainers used for hydraulic brake fluid must
be kept absolutely clean.
lDo not store hydraulic brake fluid in an unsealed
container, it will absorb water and in this
condition would be dangerous to use due to a
lowering of its boiling point.
lDo not allow hydraulic brake fluid to be
contaminated with mineral oil, or put new
hydraulic brake fluid in a container which has
previously contained mineral oil.
lDo not re-use hydraulic brake fluid previously
removed from the system.
lAlways use clean brake fluid or a recommended
alternative to clean hydraulic components.
lFit a blanking cap to a hydraulic union and a
plug to its socket, immediately after
disconnection of pipes and hoses to prevent the
ingress of dirt.
lAbsolute cleanliness must be observed when
working with hydraulic components.
lIt is imperative that the correct brake fittings are
used and that threads of components are
compatible.
Cooling system caps and plugs
Extreme care is necessary when removing engine
cooling system expansion tank caps and coolant
drain or bleed screws when the engine is hot, and
especially if it is overheated.
To avoid the possibility of scalding allow the engine
to cool before attempting coolant cap or plug
removal.
Environmental Precautions
General
This section provides general information which can
help to reduce adverse environmental impacts
incurred through the activities carried out in
workshops.
Emissions to air
Many of the activities that are carried out in
workshops emit gases and fumes which contribute to
global warming, depletion of the ozone layer and/or
the formation of photo-chemical smog at ground
level. By considering and controlling how the
workshop activities are carried out, these gases and
fumes can be minimised, thus reducing the damage
to the environment.
Exhaust fumes
Running car engines is an essential part of workshop
activities and exhaust fumes need to be ventilated to
atmosphere. However, the amount of time engines
are running and the position of the vehicle should be
carefully considered at all times, to reduce the
release of poisonous gases and minimise the
inconvenience to people living nearby.
Solvents
Some of the cleaning agents used are solvent based
and will evaporate to atmosphere if used carelessly,
or if cans are left unsealed. All solvent containers
should be firmly closed when not needed and solvent
should be used sparingly. Suitable alternative
materials may be available to replace some of the
commonly used solvents. Similarly, many paints are
solvent based and the spray should be minimised to
reduce solvent emissions.
Refrigerant
It is illegal to release any refrigerants into the
atmosphere. Discharge and replacement of these
materials from air conditioning units should only be
carried out using the correct equipment.
Checklist
Always adhere to the following:
Engines –
ldon't leave engines running unnecessarily;
lminimise testing times and check where the
exhaust fumes are being blown.

General fitting instructions
Precautions against damage
To avoid damage to the vehicle when carrying out
repairs, always adhere to the following:
lAlways fit wing and seat covers before
commencing work. Avoid spilling brake fluid or
battery acid on paintwork; immediately wash off
with water if this occurs.
lDisconnect the battery earth lead before starting
work, see ELECTRICAL PRECAUTIONS.
lAlways use the recommended service tool or a
satisfactory equivalent where specified.
lProtect exposed bearing surfaces, sealing
surfaces and screw threads from damage.
Component removal
Whenever possible, clean components and
surrounding area before removal.
lBlank off openings exposed by component
removal.
lImmediately seal fuel, oil or hydraulic lines when
apertures are exposed; use plastic caps or
plugs to prevent loss of fluid and ingress of dirt.
lClose open ends of oilways exposed by
component removal with tapered hardwood
plugs or conspicuous plastic plugs.
lImmediately a component is removed, place it in
a suitable container; use a separate container
for each component and its associated parts.
lClean bench and provide marking materials,
labels, containers and locking wire before
dismantling a component.
Dismantling
Observe scrupulous cleanliness when dismantling
components, particularly when brake, fuel or
hydraulic system parts are being worked on. A
particle of dirt or a cloth fragment could cause a
serious malfunction if trapped in these systems.Use the following procedures:
lBlow out all tapped holes, crevices, oilways and
fluid passages with an air line. Ensure that any
O-rings used for sealing are correctly replaced
or renewed if disturbed during the process.
lUse marking ink to identify mating parts and
ensure correct reassembly. Do not use a centre
punch or scriber to mark parts, they could
initiate cracks or distortion in marked
components.
lWire together mating parts where necessary to
prevent accidental interchange (e.g. roller
bearing components).
lWire labels on to all parts which are to be
renewed, and to parts requiring further
inspection before being passed for reassembly;
place these parts in separate containers from
those containing parts for rebuild.
lDo not discard a part due for renewal until after
comparing it with a new part to ensure that its
correct replacement has been obtained.
Cleaning components
Always use the recommended cleaning agent or
equivalent. Ensure that adequate ventilation is
provided when volatile degreasing agents are being
used. Do not use degreasing equipment for
components containing items which could be
damaged by the use of this process.
When washing under bonnet, never direct water onto
ECM, as water ingress may occur resulting in
damage to electrical components inside.
General Inspection
All components should be inspected for wear or
damage before being reassembled.
lNever inspect a component for wear or
dimensional check unless it is absolutely clean;
a slight smear of grease can conceal an
incipient failure.
lWhen a component is to be checked
dimensionally against recommended values,
use the appropriate measuring equipment
(surface plates, micrometers, dial gauges etc.).
Ensure the measuring equipment is calibrated
and in good serviceable condition.
lReject a component if its dimensions are
outside the specified tolerances, or if it appears
to be damaged.
lA part may be refitted if its critical dimension is
exactly to its tolerance limit and it appears to be
in satisfactory condition.
lUse 'Plastigauge' 12 Type PG-1 for checking
bearing surface clearances.

GENERAL INFORMATION
03-9
Oil seals
General
Always renew oil seals which have been removed
from their working location (whether as an individual
component or as part of an assembly). NEVER use
a seal which has been improperly stored or handled,
such as hung on a hook or nail.
lCarefully examine seal before fitting to ensure
that it is clean and undamaged.
lEnsure the surface on which the new seal is to
run is free of burrs or scratches. Renew the
component if the original sealing surface cannot
be completely restored.
lProtect the seal from any surface which it has to
pass when being fitted. Use a protective sleeve
or tape to cover the relevant surface.
lCertain oil seals are coated with a protective
wax and must be fitted dry unless stated
otherwise. Where an oil seal needs to be
lubricated prior to fitment, lubricate the sealing
lips with a recommended lubricant before use to
prevent damage during initial use. On dual
lipped seals, smear the area between the lips
with grease.
lIf a seal spring is provided, ensure that it is fitted
correctly.
lPlace lip of seal towards fluid to be sealed and
slide into position on shaft. Use fitting sleeve
where possible to protect sealing lip from
damage by sharp corners, threads or splines. If
a fitting sleeve is not available, use plastic tube
or tape to prevent damage to the sealing lip.
lGrease outside diameter of seal, place square
to housing recess and press into position using
great care, and if possible a 'bell piece' to
ensure that seal is not tilted. Never let weight of
unsupported shaft rest in seal.lUse the recommended service tool to fit an oil
seal. If the correct service tool is not available,
use a suitable tube approximately 0.4 mm
(0.015 in.) smaller than the outside diameter of
the seal. Use a hammer VERY GENTLY on
drift if a suitable press is not available.
lPress or drift the seal in to the depth of its
housing with the sealing lip facing the lubricant
to be retained if the housing is shouldered, or
flush with the face of the housing where no
shoulder is provided. Ensure that the seal does
not enter the housing in a tilted position.

GENERAL INFORMATION
03-10
Joints and joint faces
General
Fit joints dry unless specified otherwise.
lAlways use the correct gaskets as specified.
lWhen joining compound is used, apply in a thin
uniform film to metal surfaces; take care to
prevent joining compound from entering
oilways, pipes or blind tapped holes.
lIf gaskets and/or joining compound is
recommended for use; remove all traces of old
joining material prior to reassembly. Do not use
a tool which will damage the joint faces and
smooth out any scratches or burrs using an oil
stone. Do not allow dirt or joining material to
enter any tapped holes or enclosed parts.
lPrior to reassembly, blow through any pipes,
channels or crevices with compressed air.
Locking devices
General
Always replace locking devices with one of the same
design.
Tab Washers
Always release locking tabs and fit new locking
washers, do not re-use locking tabs. Ensure the new
tab washer is the same design as that replaced.
Locking Nuts
Always use a backing spanner when loosening or
tightening locking nuts, brake and fuel pipe unions.
Roll Pins
Always fit new roll pins of an interference fit in the
hole.
Circlips
Always fit new circlips of the correct size for the
groove.
Locking wire
Always fit locking wire of the correct type. Arrange
wire so that its tension tends to tighten the bolt heads
or nuts to which it is fitted.
Keys and Keyways
Remove burrs from edges of keyways with a fine file
and clean thoroughly before attempting to refit key.
Clean and inspect key closely; keys are suitable for
refitting only if indistinguishable from new, as any
indentation may indicate the onset of wear.

GENERAL INFORMATION
03-11
Split pins
Always fit new split-pins of the correct size for the
hole in the bolt or stud.
Screw threads
General
Metric threads to ISO standards are used.
Damaged nuts, bolts and screws must always be
discarded. Cleaning damaged threads with a die or
tap impairs the strength and closeness of fit of the
threads and is not recommended.
Always ensure that replacement bolts are at least
equal in strength to those replaced.
Castellated nuts must not be slackened to accept a
split-pin, except in recommended cases when this
forms part of an adjustment.
Do not allow oil or grease to enter blind threaded
holes. The hydraulic action on screwing in the bolt or
stud could split the housing.
Always tighten a nut or bolt to the recommended
torque figure. Damaged or corroded threads can
affect the torque reading.
To check or re-tighten a bolt or screw to a specified
torque figure, first loosen a quarter of a turn, then
retighten to the correct torque figure.
Oil thread lightly before tightening to ensure a free
running thread, except in the case of threads treated
with sealant/lubricant, and self-locking nuts.

GENERAL INFORMATION
03-31
When a major repair has been completed, a leak test
should be conducted; refer to the air conditioning
section of this manual for the correct procedure.
Refrigerant oil
Use an approved refrigerant lubricating oil:
ND Oil 8
CAUTION: Do not use any other type of
refrigerant oil.
CAUTION: Refrigerant oil easily absorbs water
and must not be stored for long periods. Do not
pour unused oil back into the container.
When renewing system components, add the
quantities of refrigerant oil recommended in the Air
Conditioning section of this manual.
Compressor
A new compressor is sealed and pressurised with
Nitrogen gas. When fitting a new compressor, slowly
release the sealing cap; gas pressure should be
heard to vent as the seal is broken.
CAUTION: A new compressor should always be
sealed and could be pressurised with nitrogen
gas. To avoid possible oil loss, release the
sealing cap(s) slowly. Do not remove the cap(s)
until immediately prior to connecting the air
conditioning pipes to the compressor.
Rapid refrigerant discharge
If the air conditioning system is involved in accident
damage and the system is punctured, the refrigerant
will discharge rapidly. The rapid discharge of
refrigerant will also result in the loss of most of the
oil from the system. The compressor must be
removed and all the remaining oil in the compressor
drained and refilled in accordance with the 'Air
Conditioning Compressor Replacement Procedure'.
Air conditioning compressor
replacement
A new compressor is supplied filled with a full charge
of (X cm3) of refrigerant oil.
A new compressor is supplied with an oil fill (X cm) of
120 cm
3.
A calculated quantity of oil must be drained from the
new compressor before fitting. To calculate the
quantity of oil to be drained:
1Remove the drain plug from the old
compressor.
2Invert the compressor and gravity drain the oil
into a calibrated measuring cylinder. Rotate the
compressor clutch to ensure the compressor is
completely drained.
3Note the quantity of oil drained (Y cm
3).
4Calculate the quantity of oil to be drained from
the new compressor using the following
formula:
X cm
3 – (Y cm3 + 20 cm3) = Q cm3
5Remove the drain plug from the new
compressor and drain Q cm3 of oil.
6Fit and tighten the compressor drain plug.
System components
When renewing system components, add the
following quantities of refrigerant oil:
lCondenser = 40 cm
3
lEvaporator = 30 cm 3
lReceiver drier = 15 cm 3
lPipe or hose = 5 cm 3

Fluids
Fuel
Always use the following recommended fuels:
Petrol engines
Use unleaded petrol with a minimum octane rating of
95 RON to ENN 228 specification.
In an emergency (and only if the correct fuel is
unavailable), lower octane rated fuel can be used for
very limited periods of moderate, low speed
motoring, provided engine 'knocking' does not occur.
Fuels of 90 RON is used in certain markets; 90 RON
fuel can be used regularly ONLY if the engine has
been tuned specifically to suit low octane fuel.
Certain markets use fuel containing a 23% Ethanol
additive.
K1.8 and KV6 engines are also available for use with
a low octane leaded fuel specification in some
markets.
Diesel engines
Use a good quality diesel fuel or automotive gas oil
(AGO) conforming to EN 590 specification.
It is important that the sulphur content of diesel fuel
does not exceed 0.3%.
Ensure the fuel filter element is changed at the
recommended intervals.
+ MAINTENANCE, MAINTENANCE, Fuel
Filter - Diesel.
Brake Fluid
Use only DOT 4 brake fluid. DO NOT use brake fluid
of a different specification.
PAS fluid
Use Texaco 9226 fluid.Anti-freeze solutions
The overall anti-freeze concentration should not fall,
by volume, below 50% to ensure that the anti-
corrosion properties of the coolant are maintained.
Anti-freeze concentrations greater than 60% are not
recommended as cooling efficiency will be impaired.
Use Havoline Extended Life Coolant (XLC), or any
ethylene glycol based anti-freeze (containing no
methanol) with only Organic Acid Technology (OAT)
corrosion inhibitors, to protect the cooling system.
CAUTION: No other anti-freeze should be used
with Havoline Extended Life Coolant.
The cooling system should be drained, flushed and
refilled with the correct amount of anti-freeze
solution at the intervals given on the Service
Maintenance Check Sheet.
After filling with anti-freeze solution, attach a warning
label to a prominent position on the vehicle stating
the type of anti-freeze contained in the cooling
system to ensure that the correct type is used for
topping-up.
The following recommended quantities of anti-freeze
will provide frost protection to -36 °C (-33 °F):
Engine – Td4
