WORKSHOP MAINTENANCE

This section covers workshop maintenance

for the V8 and Tdi engines only. Maintenance

of Td5 and 4-cylinder petrol models should be

referred to a qualified dealer.

It is recommended that the maintenance

procedures covered in this section of the

handbook, should only be carried out by

qualified personnel in a fully equipped

workshop; preferably an authorised Land

Rover dealer. However, if the vehicle is being

operated in a remote area, where full

workshop facilities are not available, some

maintenance can be carried out, provided that

it is completed in safe conditions by

experienced personnel.

WARNING

DO NOT carry out any maintenance in dusty,

damp or dirty conditions.

NOTE: Some of the servicing procedures

require specialised knowledge and equipment,

and therefore MUST be carried out by a

qualified person, familiar with the

maintenance and safety procedures practised

by Land Rover dealers. These NECESSARY

procedures are NOT covered in this handbook

and should be referred to a Land Rover dealer.

Servicing schedules

In normal operating conditions, servicing

should be carried out at intervals of 10,000

km (6,000 miles) or every six months,

whichever is sooner.

IMPORTANT INFORMATION

Special operating conditions

When a vehicle is operated in extremely

arduous conditions, or on dusty, wet or

muddy terrain, more frequent attention

must be paid to servicing requirements.

For example; if your vehicle experiences

deep wading conditions, even DAILY

servicing could be necessary to ensure

the continued safe and reliable operation

of the vehicle.

Contact a Land Rover dealer for advice.

Emission control

Your vehicle is fitted with various items of

emission control equipment, designed to meet

specific territorial requirements.

You should be aware that unauthorised

replacement, modification or tampering with

this equipment by an owner or motor vehicle

repairer, may be unlawful and subject to legal

penalties.

In addition, engine settings must NOT be

tampered with. These have been established

to ensure that your vehicle complies with

stringent exhaust emission regulations.

Incorrect engine settings may adversely affect

exhaust emissions, engine performance and

fuel consumption, as well as causing high

temperatures, which will result in damage to

the catalytic converter (if fitted) and the

vehicle.

Replacement parts

It is essential that only Land Rover parts are

used, safety features embodied in the vehicle

may be impaired if other, non-approved parts

are used. In certain territories, legislation

prohibits the fitting of parts not to the

manufacturer’s specification.

WARNING

The fitting of parts of inferior quality, or the

carrying out of non-approved alterations or

conversions, may be dangerous and could

affect the safety of the vehicle and

occupants. It could also invalidate the terms

and conditions of the vehicle warranty.

Road testing on dynamometers

(’rolling roads’)

WARNING

Because your vehicle is equipped with

permanent four-wheel drive, it is essential

that any dynamometer testing is carried out

ONLY by a qualified person, familiar with

the dynamometer testing and safety

procedures practised by Land Rover

dealers. Contact your Land Rover dealer for

further information.

SAFETY IN THE GARAGE

Whenever you carry out maintenance on

your vehicle, the following safety

precautions should be observed at all times.

• ALWAYS keep hands, tools and items of

clothing clear of all drive belts and pulleys

whilst they are in operation.

• DO NOT touch exhaust or cooling system

components until they are cool.

• DO NOT touch electrical leads or

components with the starter switch turned

on.

• NEVER leave the engine running in an

unventilated area; exhaust gases are

poisonous and contain carbon monoxide,

which can cause unconsciousness and

can be fatal.

• DO NOT work beneath the vehicle with the

lifting jack as the only means of support.

• Ensure sparks and naked lights are kept

away from the engine and battery

compartments.

• DO NOT use any lubricants, solvents or

sealants etc, without first reading any

warnings and instructions supplied with

these substances; they could be harmful if

improperly used.

WARNING

Remember, cooling fans and air

conditioning system condenser fans (if

fitted), may continue to operate after the

engine is switched off. Always wait until the

fans have completely stopped moving before

working in the engine compartment.

Fuel system safety

Fuel vapour is highly flammable and in

confined spaces, is also very explosive and

toxic. When fuel evaporates, it produces 150

times its own volume in vapour and when

mixed with air, becomes an easily ignitable

mixture; consequently even a small spillage is

very dangerous.

It is recommended that you always have a

FOAM, CO

GAS, or POWDER type fire

extinguisher close at hand when working with

fuel or the fuel system.

ALWAYS disconnect the battery negative lead

BEFORE carrying out work on the fuel system.

WARNING

Under no circumstances should any part of

the fuel system be dismantled or replaced

by anyone other than a suitably qualified

motor vehicle technician. Failure to comply

with this instruction may result in fuel

spillage with a consequent serious risk of

fire.

It is imperative that the battery is

disconnected BEFORE and not during any

work on the fuel system, as arcing at the

battery terminal could ignite fuel vapour in

the atmosphere.

Whenever fuel is being handled, transferred

or stored, or when carrying out work on the

fuel system, all forms of ignition MUST be

extinguished or removed, any lighting being

used M UST be flameproof and kept clear of

the fuel.

Poisonous liquids

Most liquids and lubricants used in motor

vehicles are poisonous and should not be

consumed or brought into contact with open

wounds. These include; battery acid,

anti-freeze, brake, clutch and power steering

fluid, as well as petrol, diesel, engine oil and

windscreen washer additives.

For your own safety, ALWAYS read and obey

all instructions printed on labels and

containers.

Used engine oil

Prolonged contact with engine oil can cause

serious skin disorders, including dermatitis

and skin cancer. ALWAYS wash thoroughly

after contact.

It is illegal to pollute drains, water courses or

soil with toxic chemicals such as used engine

oil. ALWAYS dispose of vehicle liquids and

lubricants at authorised waste disposal sites,

or at garages which provide facilities for the

receipt of discharged batteries, used engine

oil and toxic chemicals. If in doubt, contact

your Local Authority for advice.
