pages will be issued to ensure that the manual
covers latest models. Amendments and additions
will be identified by the addition of a dated footer
at the bottom of the page.
This Workshop Manual is designed to assist skilled
technicians in the efficient repair and maintenance of
Land Rover vehicles.
Individuals who undertake their own repairs
should have some skill and training, and limit
repairs to components which could not affect the
safety of the vehicle or its passengers. Any
repairs required to safety critical items such as
steering, brakes, suspension or supplementary
restraint system should be carried out by a Land
Rover Dealer. Repairs to such items should
NEVER be attempted by untrained individuals.
WARNINGS, CAUTIONSandNOTESare given
throughout this Manual in the following form:
WARNING: Procedures which must be
followed precisely to avoid the possibility
of personal injury.
CAUTION: This calls attention to
procedures which must be followed to
avoid damage to components.
NOTE: This calls attention to methods
which make a job easier or gives helpful
information.
DIMENSIONS
The dimensions quoted are to design engineering
specification. Alternative unit equivalents, shown in
brackets following the dimensions, have been
converted from the original specification.REFERENCES
References to the left or right hand side in the manual
are made when viewing the vehicle from the rear.
With the engine and gearbox assembly removed, the
water pump end of the engine is referred to as the
front.
To reduce repetition, some operations covered in this
Manual do not include reference to testing the vehicle
after repair.
It is essential that work is inspected and tested after
completion and if necessary a road test of the vehicle
is carried out particularly where safety related items
are concerned.
REPAIRS AND REPLACEMENTS
When replacement parts are required it is essential
that Land Rover parts are used.
Attention is particularly drawn to the following points
concerning repairs and the fitting of replacement parts
and accessories: Safety features embodied in the
vehicle may be impaired if other than Land Rover
parts are fitted. In certain territories, legislation
prohibits the fitting of parts not to the vehicle
manufacturer's specification. Torque spanner values
given in the Workshop Manual must be strictly
adhered to. Locking devices, where specified, must be
fitted. If the efficiency of a locking device is impaired
during removal it must be replaced with a new one.
Certain fasteners must not be re-used. These
fasteners are specified in the Workshop Manual.
POISONOUS SUBSTANCES
Many liquids and other substances used are
poisonous and therefore must not be consumed. It is
also advisable to keep all substances away from open

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 course in 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, or a
satisfactory equivalent, where specified.
5.Protect temporarily exposed screw threads by
replacing nuts or fitting plastic caps.SAFETY PRECAUTIONS
1.Whenever possible use a lift or pit 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 negative lead.
WARNING: Do not disconnect any pipes in
air conditioning refrigeration 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 nuts
or fittings; as well as causing damage to
protective coatings, there is a risk of damage to
electronic equipment and brake linings from
stray heat.

INFORMATION PREPARATION
1.Before removing a component, clean it and its
surrounding areas as thoroughly as possible.
2.Blank off any openings exposed by component
removal, using greaseproof paper and masking
tape.
3.Immediately seal fuel, oil or hydraulic lines when
separated, using plastic caps or plugs, to
prevent loss of fluid and entry of dirt.
4.Close open ends of oilways, exposed by
component removal, with tapered hardwood
plugs or readily visible plastic plugs.
5.Immediately a component is removed, place it in
a suitable container; use a separate container for
each component and its associated parts.
6.Before dismantling a component, clean it
thoroughly with a recommended cleaning agent;
check that agent is suitable for all materials of
component.
7.Clean bench and provide marking materials,
labels, containers and locking wire before
dismantling a component.
DISMANTLING
1.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 dangerous malfunction if trapped
in these systems.
2.Blow 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.
3.Use marking ink to identify mating parts, to
ensure correct reassembly. If a centre punch or
scriber is used they may initiate cracks or
distortion of components.
4.Wire together mating parts where necessary to
prevent accidental interchange (e.g. roller
bearing components).
5.Wire 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.
6.Do not discard a part due for renewal until after
comparing it with a new part, to ensure that its
correct replacement has been obtained.INSPECTION-GENERAL
1.Never inspect a component for wear or
dimensional check unless it is absolutely clean;
a slight smear of grease can conceal an incipient
failure.
2.When a component is to be checked
dimensionally against figures quoted for it, use
correct equipment (surface plates, micrometers,
dial gauges, etc.) in serviceable condition.
Makeshift checking equipment can be
dangerous.
3.Reject a component if its dimensions are outside
limits quoted, or if damage is apparent. A part
may, however, be refitted if its critical dimension
is exactly limit size, and is otherwise satisfactory.
4.Use 'Plastigauge' 12 Type PG-1 for checking
bearing surface clearances. Directions for its
use, and a scale giving bearing clearances in
0,0025 mm steps are provided with it.

INFORMATION JOINTS AND JOINT FACES
1.Always use correct gaskets where they are
specified.
2.Use jointing compound only when
recommended. Otherwise fit joints dry.
3.When jointing compound is used, apply in a thin
uniform film to metal surfaces; take great care to
prevent it from entering oilways, pipes or blind
tapped holes.
4.Remove all traces of old jointing materials prior
to reassembly. Do not use a tool which could
damage joint faces.
5.Inspect joint faces for scratches or burrs and
remove with a fine file or oil stone; do not allow
removed material or dirt to enter tapped holes or
enclosed parts.
6.Blow out any pipes, channels or crevices with
compressed air, fit new 'O' rings or seals
displaced by air blast.FLEXIBLE HYDRAULIC PIPES, HOSES
1.Before removing any brake or power steering
hose, clean end fittings and area surrounding
them as thoroughly as possible.
2.Obtain appropriate plugs or caps before
detaching hose end fittings, so that ports can be
immediately covered to exclude dirt.
3.Clean hose externally and blow through with
airline. Examine carefully for cracks, separation
of plies, security of end fittings and external
damage. Reject any hose found faulty.
4.When refitting hose, ensure that no unnecessary
bends are introduced, and that hose is not
twisted before or during tightening of union nuts.
5.Containers for hydraulic fluid must be kept
absolutely clean.
6.Do not store brake fluid in an unsealed
container. It will absorb water, and fluid in this
condition would be dangerous to use due to a
lowering of its boiling point.
7.Do not allow brake fluid to be contaminated with
mineral oil, or use a container which has
previously contained mineral oil.
8.Do not re-use brake fluid bled from system.
9.Always use clean brake fluid to clean hydraulic
components.
10.Fit a cap to seal a hydraulic union and a plug to
its socket after removal to prevent ingress of dirt.
11.Absolute cleanliness must be observed with
hydraulic components at all times.
12.After any work on hydraulic systems, inspect
carefully for leaks underneath the vehicle while a
second operator applies maximum pressure to
the brakes (engine running) and operates the
steering.

LUBRICATION PRACTICE
Use a high quality oil of the correct viscosity range and service classification in the engine during maintenance and
when topping up. The use of oil not to the correct specification can lead to high oil and fuel consumption and
ultimately to damaged components.
Oil to the correct specification contains additives which disperse the corrosive acids formed by combustion and
prevent the formation of sludge which can block the oilways. Additional oil additives should not be used. Always
adhere to the recommended servicing intervals.
WARNING: Many liquids and other substances used in motor vehicles are poisonous. They must
not be consumed and must be kept away from open wounds. These substances, among others,
include anti-freeze windscreen washer additives, lubricants and various adhesives.

MAINTENANCE
CHECK/TOP UP COOLING SYSTEM
1.To prevent corrosion of aluminium alloy engine
parts it is imperative that cooling system is filled
with a solution of water and phosphate free
anti-freeze, winter or summer. Never fill or top up
with plain water.
WARNING: Do not remove filler cap when
engine is hot because cooling system is
pressurised and personal scalding could
result.
2.When removing filler cap, turn cap slowly
anti-clockwise, pause and allow all pressure to
escape.
3.Continue to turn until cap is removed.
4.When engine is cold expansion tank coolant
should be level with top of indicator post, visible
inside tank through filler hole.
5.If necessary, top up cooling system with
premixed coolant. Use soft water whenever
possible, if local water supply is hard, rainwater
should be used.
6.When replacing filler cap it is important that it is
tightened down fully. Failure to tighten filler cap
properly may result in water loss, with possible
damage to engine
The cooling system should be drained and flushed at
2 year intervals or at onset of second winter. Refer to
Coolant Requirements.
