INFORMATION REV: 05/99 INTRODUCTION
This workshop manual covers vehicles from 1996
model year onwards. Amendments and additional
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 Defender 300Tdi, Td5, and V8i 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
crankshaft 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
wounds. These substances among others include
anti-freeze, brake fluid, fuel, windscreen washer
additives, air conditioning refrigerant, lubricants and
various adhesives.

Engine coolant
(Pre-99MY)Use an ethylene glycol based anti-freeze (containing no methanol) with non-phosphate
corrosion inhibitors suitable for use in aluminium engines to ensure the protection of the
cooling system against frost and corrosion in all seasons. Use one part anti-freeze to
one part water for protection down to -36°C (-33°F).
IMPORTANT: Coolant solution must not fall below proportions one part
anti-freeze to three parts water, i.e. minimum 25% anti-freeze in coolant otherwise
damage to engine is liable to occur. Maximum concentration is 60%.
Engine coolant
(99MY on)Use Texaco XLC long life coolant. Use one part anti-freeze to one part water for
protection down to -36°C (-33°F).
IMPORTANT: Coolant solution must not fall below 50% anti-freeze otherwise
damage to the engine is liable to occur. Maximum concentration is 60%.

Compressor Oil Sanden oil
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.

NOTE: * All levels must be checked by dipstick or level plugs as applicable.
ANTI-FREEZE
PERCENTAGE CONCENTRATION - 50%
PROTECTION - LOWER TEMPERATURE LIMIT
Complete protection
Vehicle may be driven away immediately from cold,
-33°C (-36°F).
Safe limit protection
Coolant in semi-frozen state. Engine may be started
and driven away after warm-up period, -41°C (-42°
F).Lower protection
Prevents frost damage to cylinder head, block and
radiator. Thaw out before starting engine, -47°C (-53°
F).
CAUTION: Anti-freeze content must never
be allowed to fall below 25% (pre 99MY) or
50% (99MY on) otherwise damage to the
engine is liable to occur. Anti-freeze content
should not exceed 60% (all models) as this will
greatly reduce cooling efficiency.

the fluid level below 'MIN' mark.
Brake fluid will damage painted surfaces; clean up
any spillage immediately and rinse with plenty of
water.
If brake fluid should come into contact with skin
or eyes, rinse immediately with plenty of water.
1.Check the fluid level visually through transparent
side of reservoir without removing cap.
