INFORMATIONREV: 05/99 ACCESSORIES AND CONVERSIONS
DO NOT FITunapproved accessories or conversions,
as they could affect the safety of the vehicle.
Land Rover will not accept liability for death, personal
injury, or damage to property which may occur as a
direct result of the fitting of non-approved conversions
to the vehicle.
WHEELS AND TYRES
WARNING: DO NOT replace the road
wheels with any type other than genuine
Land Rover wheels which are designed for
multi-purpose on and off road use and have very
important relationships with the proper operation
of the suspension system and vehicle handling.
Replacement tyres must be of the make and sizes
recommended for the vehicle, and all tyres must
be the same make, ply rating and tread pattern.
STEAM CLEANING
To prevent consequential rusting, any steam cleaning
within the engine bayMUSTbe followed by careful
re-waxing of the metallic components affected.
Particular attention must be given to the steering
column, engine coolant pipes and hose clips.
SPECIFICATION
The specification details and instructions set out in
this Manual apply only to a range of vehicles and not
to any one. For the specification of a particular vehicle
purchasers should consult their Dealer.
The Manufacturer reserves the right to vary
specifications with or without notice, and at such times
and in such manner as it thinks fit. Major as well as
minor changes may be involved in accordance with
the Manufacturer's policy of constant product
improvement.
Whilst every effort is made to ensure the accuracy of
the particulars contained in this Manual, neither the
Manufacturer or Dealer, by whom this Manual is
supplied, shall in any circumstances be held liable for
any inaccuracy or the consequences thereof.SPECIAL SERVICE TOOLS
The use of approved special service tools is
important. They are essential if service operations are
to be carried out efficiently, and safely. Where special
tools are specified,only these tools should be used
to avoid the possibility of personal injury or
damage to the components.Also, the amount of
time which they save can be considerable.
Special tools bulletins will be issued periodically giving
details of new tools as they are introduced.
All orders and enquiries from the United Kingdom
should be sent direct to Cartool (UK) Ltd. Overseas
orders should be placed with the local Cartool
distributor, where one exists. Countries where there is
no distributor may order direct from:
Cartool (UK) Ltd.

INFORMATION 3.Position an axle stand under right hand axle
tube, carefully lower jack until axle sits securely
on both axle stands, remove trolley jack.
4.Before commencing work on underside of
vehicle re-check security of vehicle on stands.
5.Reverse procedure when removing vehicle from
stands.
Raise rear of vehicle
1.Position cup of hydraulic arm under differential
casing.
2.Raise vehicle to enable axle stands to be
installed under left and right hand axle tubes.
3.Lower jack until axle sits securely on axle
stands, remove trolley jack.
4.Before commencing work on underside of
vehicle re-check security of vehicle on stands.
5.Reverse procedure when removing vehicle from
stands.
HYDRAULIC VEHICLE RAMP (FOUR POST)
Use only a 'drive on' type ramp which supports vehicle
on its road wheels. If a 'wheel-free' condition is
required, use a 'drive on' ramp incorporating a
'wheel-free' system providing support beneath axle
casings. Alternatively, place vehicle on a firm, flat floor
and support on axle stands.
TWO POST VEHICLE RAMPS
The manufacturer of LAND ROVER VEHICLES
DOES NOT recommend using 'Two Post' ramps
that employ four adjustable support arms. These
are NOT considered safe for Land Rover vehicles.
If vehicle is installed on a Two Post ramp
responsibility for safety of vehicle and personnel
performing service operations is in the hands of
the Service Provider.DYNAMOMETER TESTING
The front and rear axles cannot be driven
independently.
WARNING: DO NOT attempt to drive
individual wheels with vehicle supported
on floor jacks or stands.
Four wheel dynamometers
Provided that front and rear dynamometer rollers are
rotating at identical speeds and that normal workshop
safety standards are applied, there is no speed
restriction during testing except any that may apply to
the tyres.
Two wheel dynamometers
IMPORTANT: Use a four wheel dynamometer for
brake testing if possible.
If brake testing on a single axle rig is necessary it
must be carried out with propeller shaft to rear axle
removed, AND neutral selected in BOTH main
gearbox and transfer gearbox. When checking brakes,
run engine at idle speed to maintain servo vacuum.
If checking engine performance, the transfer box must
be in high range and propeller shaft to stationary axle
must be removed.

INFORMATION FAULT DIAGNOSTIC EQUIPMENT
TESTBOOK
For Defender models fitted with the vehicle Anti-theft
Immobilisation and Alarm System, diagnostic
equipment, named TestBook, is available to assist in
the diagnostic and fault finding abilities of the Dealer
workshop. A diagnostic connector, located under the
front centre seat, or cubby box, as shown below, is
provided to facilitate the procedures.
If an exhaust gas recirculation (EGR) system is fitted,
this too can be checked using TestBook. A diagnostic
connector, also located under the front centre seat or
cubby box, is provided.
Features of Testbook include :-
Fully upgradable support for the technician.
Structured diagnostics to accommodate all skill levels.
Touch screen operation.
Direct print out of screen information and test results.READING THIS MANUAL
This manual is divided into sections shown on the
contents page, alongside a range of icons, familiar to
service technicians.
Relevant information is contained within each of these
sections. These are further divided into the following
sub-sections which appear at the foot of each page :-
Description and operation.
Fault diagnosis.
Adjustment.
Repair.
Overhaul.
Specifications, Torque.
To avoid repeating information through the sections,
where part of the repair operation impacts on another
section, a cross reference is given to direct the reader
to where the information is sited.
For example:
The maintenance section states the need to renew
drive belt. A cross reference sites this information in:
Section 12 Engine
- Sub-section: Repairs
- Heading: Drive belt renew.

GENERAL FITTING REMINDERS

INFORMATION GENERAL FITTING REMINDERS
WORKSHOP SAFETY IS YOUR RESPONSIBILITY!
The suggestions, cautions and warnings in the
section are intended to serve as reminders for
trained and experienced mechanics. This manual
is not a definitive guide to automotive mechanics
or workshop safety.
Shop equipment, shop environment, and the use
and disposal of solvents, fluids, and chemicals
are subject to government regulations which are
intended to provide a level of safety. It is your
responsibility to know and comply with such
regulations.
PRECAUTIONS AGAINST DAMAGE
1.Always fit covers to protect fenders before
commencing work in engine compartment.
2.Cover seats and carpets, wear clean overalls
and wash hands or wear gloves before working
inside vehicle.
3.Avoid spilling hydraulic fluid or battery acid on
paint work. Wash off with water immediately if
this occurs. Use Polythene sheets to protect
carpets and seats.
4.Always use a recommended Service Tool where
specified.
5.Protect temporarily exposed screw threads by
replacing nuts or fitting plastic caps.SAFETY PRECAUTIONS
1.Whenever possible, use a lift when working
beneath vehicle, in preference to jacking. Chock
wheels as well as applying parking brake.
WARNING: Do not use a pit when
removing fuel system components.
2.Never rely on a jack alone to support vehicle.
Use axle stands carefully placed at jacking
points to provide rigid support.
3.Ensure that a suitable form of fire extinguisher is
conveniently located.
4.Check that any lifting equipment used has
adequate capacity and is fully serviceable.
5.Disconnect battery.
WARNING: Do not disconnect any pipes in
air conditioning system, unless trained
and instructed to do so. A refrigerant is
used which can cause blindness if allowed to
contact eyes.
6.Ensure that adequate ventilation is provided
when volatile degreasing agents are being used.
7.Do not apply heat in an attempt to free stiff
fixings; as well as causing damage to protective
coatings, there is a risk of damage to electronic
equipment and brake linings from stray heat.
