FOREWORD

r

Every possible care is taken during the manufacture of De Lorean

cars to ensure they leave the

faciory

capable of giving

many

miles of trouble free

motoring.

Proper servicing is absolutely

essential if satisfactory performance is to be maintained.

_

Indexing System

The

various

units and systems of the

vehides

are dealt with in

sections designated by a letter. This

is

further divided into

subsections which are identified by a number and a page number

within the subsections.

Pag*

A:01:12

Subsection

r

i

Each section opens with a contents and inaex page so that any

particular operation may be easily referred to.

r

General Data

Comprehensive

informaiion

regarding

dimensions

tolerances and

weights are given at the beginning of

The

manual and at the start

of each section. Dimensicns are given in both metric and imperial

units.

SERVICE ORGANISATION

Any communication relating to a De Lorean car should state the

Vehicle Identification Number

(VIN)

which can be found by

looking through the driver's side of the windshield, or on the

driver's side door shut.

DE LOREAN GENUINE PARTS

De Lorean genuine parts are identical to the high quality factory

parts installed in new De Lorean cars.

•

-

In

order to provide the best possible service for owners, the

dealer organisation throughout the world form a link between the

owner and factory. All problems related to the servicing and

repair of cars are dealt with through that organisation.

Dealers have the backing of the National Distributor and the

factory Service Department.

DE LOREAN SPECIAL TOOLS

Certain service operations are made easier by the use of specially

designed tools manufactured by Kent Moore Ltd.

These tools are essential to achieve the Flat Rate (Man Hour

Schedule) Times approved by the factory.

The use of the tools is described under the appropriate sections

and the relevant tools are listed at the beginning of each section.

GENERAL SAFETY HINTS

1.

Use the correct spanner or driver for all fastening. When fitting

new fastenings ensure the thread size is correct. Metric

fastenings are predominantly, but not exclusively used. —

2.

Never walk under a car unless it is properly supported by stands.

3. Make sure jacks or stands are positioned safely and where they

will not cause damage to the car.

4.

Always disconnect the battery before working on electrical

components or wiring.

5. When working in the engine compartment or under the car make —

sure the engine cannot be started accidentally.

6. Keep hands and clothing clear of electrically operated fans even

—

when the ignition is OFF.

7. Take care not to inhale dust from brake pads —

it

contains

asbestos which

is

a health hazard.

I

8. Treat gasoline (petrol)

with

great respect — avoid any sort of

spark or flame. Do not start syphoning by mouth; drain fuel

into

a closed container.

LEGISLATION REQUIREMENTS

Most countries have stringent regulations governing the design and

manufacture of cars, aimed mainly at maintaining standards of

safety, noise and pollution. De Lorean cars conform to the

homologation specifications required in the countries to which they

are distributed.

Alterations to the car after purchase — by changing settings or

adjustments, by addition of unapproved parts, or the fitting of

unsuitable replacement parts — can result in deviation from the

agreed specification. Such deviations can have legal consequences

and you are therefore advised not to make alterations and to ensure

that replacement parts are to the original specification.

SPECIFICATION CHANGES

1

The Company reserves the right to change the specification of the

car from time to time without notice.

This is required in order to achieve the Company's objective for

constant improvement. Before carrying out any repair refer to latest

issue of the Service Bulletins, which are designed to advise any

_.

changes in specification or repair technique.
