Safety Notice


Appropri
ate service me
thods and proper repair procedures are essential for the safe, reliable operation of all motor vehicles,
as well as the safety of the person do ing the work. This manual provides genera l directions for accomplishing service and
repair work with tested, effect ive, techniques. Following them will help assure reliability.
There are numerous variations in procedures, techniques, tools, and parts for servicing vehicles, as well as in the skill of the
person doing the work. This manual cannot possibly anticipate all such variations and provide advice or cautions as to each.
Accordingly, anyone who depart s from the instructions provided in the manua l must first establish that neither personal
safety nor vehicle integrity is compromised from choices of methods, tools or parts.
Notes, Ca
utions and Warnings
Throughout
this manual, important inform
ation is highlighted by the use of notes, cautions and warnings. NOTES give
additional information on a topic or proc edure, CAUTIONS are given to prevent da mage to the vehicle, and WARNINGS are
given to prevent personal injury.

Worksh
op Manual Organization
This
manual incorporates descript
ive, diagnostic, and repair information to help trained Jaguar technicians complete service
and rectification procedures. The informat ion can be accessed by choosing the appropriate five digit section number. For
example, Section 412-03 covers air conditioning , which is part of the Climate Control System.
The manual is organized into groups covering generic aspects of the vehicle systems; the first digit of the section
number represents a group se lected from the following:
1. General Information.
2. Chassis.
3. Powertrain.
4. Electrical.
5. Body and Paint.
Each of the groups comprises sections re lating to specific areas of the vehicle.
The second and third digits of the section number indicate the vehicle system.
The last two digits of the se ction number define the system covered, more specifically.
Each section comprises one or more of the following sub-sections:
Specification

Before inspecting a component for wear or per
forming a dimensional check,
ensure that it is absolutely clean; a slight smear
of grease can conceal an incipient failure. When a component is to be checked dimensionally against figures quoted for it,
use the correct equipment (surface plates, micrometers, dial gauges etc.) in serviceable condition. The use of makeshift
equipment can be dangerous. Reject a component if its dimensio ns are outside the limits quoted, or if damage is apparent.
A part may be refitted if its critical di mension is exactly to the limit size and it is otherwise satisfactory. Use Plastigauge 12
Type PG-1 for checking bearing surface clearance, e.g. big end bearing shell to crank jour nal. Instructions for the use of
Plastigauge and a scale giving bearing clearances in steps of 0.0025 mm (0.0001 in) are supplied with the package.

Precautions
• WAR
NINGS:
WORKING ON THE FUEL SYSTEM RESULTS IN FUEL AND FUEL VAPOUR BEING PRESENT IN THE ATMOSPHERE. FUEL
VAPOUR IS EXTREMELY FLAMMABLE, HENCE GREAT CARE MUST BE TAKEN WHILST WORKING ON THE FUEL SYSTEM.
ADHERE STRICTLY TO THE FOLLOWING PRECAUTIONS:
DO
NOT SMOKE IN THE WORK AREA.
DISP

LAY 'NO SMOKING' SIGNS AROUND THE AREA.
DISCONNECT TH

E BATTERY BEFORE WORKING ON THE FUEL SYSTEM.
DO NOT CONNEC

T/DISCONNECT ELECTRICAL CIRCUITS
, USE ELECTRICAL EQUIPMENT OR OTHER TOOLS OR
ENGAGE IN WORKING PRACTICES WHICH IN ANY WAY MAY RESULT IN THE PRODUCTION OF SPARKS.
ENS
URE THAT A CO2 FIRE EXTINGUISHER IS CLOSE AT HAND.
ENS

URE THAT DRY SAND IS AVAILABLE TO SOAK UP ANY FUEL SPILLAGE.
EMP

TY FUEL USING SUITABLE FIRE PROOF EQUIPMENT IN
TO AN AUTHORIZED EXPLOSION PROOF CONTAINER.
DO NOT EMP
TY FUEL WHILE WORKING IN A WORKSHOP OR A PIT.
ENS

URE THAT WORKING AREA IS WELL VENTILATED.
ENS

URE THAT ANY WORK ON THE FUEL SYSTEM IS ON
LY CARRIED OUT BY EXPERIENCED AND WELL QUALIFIED
MAINTENANCE PERSONNEL.
ENS
URE THAT FUME EXTRACTION EQUIPMENT IS USED WHERE APPROPRIATE.
FUME EXTRACTION EQUIPMENT MUST BE IN OPERATION WHEN SOLVENTS ARE USED E.G. TRICHLOROETHANE,
WHITE SPIRIT, SBP3, METHYLENE CHLORIDE, PERCHLORETHY LENE. DO NOT SMOKE IN THE VICINITY OF VOLATILE
DEGREASING AGENTS.
General workshop practices:
Disc
onnect the grounded termin
al of the vehicle battery.
D
o not apply heat in an attempt to free seized nuts or fitt
ings; as well as causing damage to protective coatings,
there is a risk of damage from stray heat to electronic equipment and brake lines.
Keep oils and solven
ts away from naked flames and other sour
ces of ignition.
Adhere str
ictly to handling and safety inst
ructions given on containers and labels.
E
nsure that a suitab
le form of fire extinguisher is conveniently located.
Wh
en using electrical tools and equipment, inspect the power
lead for damage and check that it is properly earthed.
D
o not leave tools, equipment, spilt oil etc. around the work area.
Working beneath a vehicle:
Wh
enever possible, use a ramp or
pit in preference to jacking.
Posit
ion chocks at the wheels as we
ll as applying the parking brake.
N
ever rely on a jack alone to support a
vehicle; use axle stands, or blocks care fully placed at the jacking points, to
provide a rigid location.
Ch
eck that any lifting equipment used has adeq
uate capacity and is fully serviceable.
Working on air conditioning systems:
D
o not disconnect any pipes of the refrigeration system
unless you are trained and instructed to do so; a refrigerant
is used which can cause blindness if allowed to come into contact with the eyes.
