Introduction
This Section provides an easy reference guide to the more common
problems which may occur during the operation of your vehicle. These
problems and their possible causes are grouped under headings
denoting various components or systems, such as Engine, Cooling
system, etc. They also refer you to the Chapter and/or Section which
deals with the problem.
Remember that successful troubleshooting is not a mysterious
“black art” practised only by professional mechanics. It is simply the
result of the right knowledge combined with an intelligent, systematic
approach to the problem. Always work by a process of elimination,
starting with the simplest solution and working through to the mostcomplex - and never overlook the obvious. Anyone can run the petrol
tank dry or leave the lights on overnight, so don’t assume that you are
exempt from such oversights.
Finally, always establish a clear idea of why a problem has occurred
and take steps to ensure that it doesn’t happen again. If the electrical
system fails because of a poor connection, check all other connections
in the system to make sure that they don’t fail as well. If a particular
fuse continues to blow, find out why - don’t just replace one fuse after
another. Remember, failure of a small component can often be
indicative of potential failure or incorrect functioning of a more
important component or system.

4 Automatic transmission
Note:Due to the complexity of the automatic transmission, it is difficult
for the home mechanic to properly diagnose and service this
component. For problems other than the following, the vehicle should
be taken to a dealer or transmission workshop.
Fluid leakage
m mAutomatic transmission fluid is a deep red colour. Fluid leaks
should not be confused with engine oil, which can easily be blown
by air flow to the transmission.
m mTo pinpoint a leak, first remove all built-up dirt and grime from the
transmission housing with degreasing agents and/or steam
cleaning. Then drive the vehicle at low speeds so air flow will not
blow the leak far from its source. Raise the vehicle and determine
where the leak is coming from. Common areas of leakage are:
a) Sump pan (Chapters 1 and 7)
b) Dipstick/filler tube (see below)
c) Transmission fluid cooler lines (Chapter 7)
d) Speedometer sensor (Chapter 7)
m mMake sure the dipstick is a tight fit inside the filler tube. If the seal
at the top of the dipstick is worn or damaged, replace the seal or
the dipstick. If fluid continues to leak from the top of the dipstick
tube, inspect the breather, which is a plastic cap secured by a clip
to the top of the extension housing. This breather can be plugged
by the noise-deadening foam installed in the transmission tunnel,
causing transmission fluid to leak from the top of the dipstick
tube.
Transmission fluid brown or has a burned smell
m mTransmission fluid burned (Chapter 1).
Shift cable problems
m
mChapter 7 deals with adjusting the shift cable. Common problems
which may be attributed to a poorly adjusted shift cable are:
a) Engine starting in gears other than Park or Neutral.
b) Indicator on shift lever pointing to a gear other than the one
actually being used.
c) Vehicle moves when in Park.
m mRefer to Chapter 7 for the shift cable adjustment procedure.
Transmission will not downshift
with accelerator pedal pressed to the floor
m mKickdown cable out of adjustment (Chapter 7).
Engine will start in gears
other than Park or Neutral
m mNeutral start/reversing light switch malfunctioning (Chapter 7).
m mShift cable out of adjustment (Chapter 7).
Transmission slips, shifts roughly, is noisy,
or has no drive in forward or reverse gears
m mThere are many probable causes for the above problems, but the
home mechanic should be concerned with only one possibility -
fluid level. Before taking the vehicle to a dealer service department
or transmission repair workshop, check the level and condition of
the fluid as described in Chapter 1. Correct the fluid level as
necessary or change the fluid if needed. If the problem persists,
have a professional diagnose the probable cause.
5 Brakes
Note:Before assuming that a brake problem exists, make sure that:
a) The tyres are in good condition and properly inflated (Chapter 1).
b) The front end alignment is correct (Chapter 10).
c) The vehicle is not loaded with weight in an unequal manner.
Vehicle pulls to one side during braking
m mIncorrect tyre pressures (Chapter 1).
m mFront end out of line (have the front end aligned).
m mUnmatched tyres on same axle.
m mRestricted brake lines or hoses (Chapter 9).
m mMalfunctioning caliper assembly (Chapter 9).
m mLoose suspension parts (Chapter 10).
m mLoose calipers (Chapter 9).
m mBrake pads contaminated with oil or grease (Chapter 9).
Noise (high-pitched squeal
when the brakes are applied)
m mFront and/or rear disc brake pads worn out. The noise comes from
the wear sensor rubbing against the disc. Replace pads with new
ones immediately (Chapter 9).
Brake roughness or chatter (pedal pulsates)
m mExcessive lateral disc runout (Chapter 9).
m mParallelism not within specifications (Chapter 9).
m mUneven pad wear caused by caliper not sliding due to improper
clearance or dirt (Chapter 9).
m mDefective disc (Chapter 9).
Excessive pedal effort required to stop vehicle
m
mMalfunctioning power brake servo (Chapter 9).
m mPartial system failure (Chapter 9).
m mExcessively worn pads (Chapter 9).
m mPiston in caliper stuck or sluggish (Chapter 9).

new material to seat against the disc.
m mAccumulator in power hydraulic system defective (see a Jaguar
dealer).
Excessive brake pedal travel
m mPartial brake system failure (Chapter 9).
m mInsufficient fluid in master cylinder (Chapters 1 and 9).
m mAir trapped in system (Chapters 1 and 9).

Glossary of technical termsREF•21
RotorIn a distributor, the rotating device
inside the cap that connects the centre
electrode and the outer terminals as it turns,
distributing the high voltage from the coil
secondary winding to the proper spark plug.
Also, that part of an alternator which rotates
inside the stator. Also, the rotating assembly
of a turbocharger, including the compressor
wheel, shaft and turbine wheel.
RunoutThe amount of wobble (in-and-out
movement) of a gear or wheel as it’s rotated.
The amount a shaft rotates “out-of-true.” The
out-of-round condition of a rotating part.
SSealantA liquid or paste used to prevent
leakage at a joint. Sometimes used in
conjunction with a gasket.
Sealed beam lampAn older headlight design
which integrates the reflector, lens and
filaments into a hermetically-sealed one-piece
unit. When a filament burns out or the lens
cracks, the entire unit is simply replaced.
Serpentine drivebeltA single, long, wide
accessory drivebelt that’s used on some
newer vehicles to drive all the accessories,
instead of a series of smaller, shorter belts.
Serpentine drivebelts are usually tensioned by
an automatic tensioner.
ShimThin spacer, commonly used to adjust
the clearance or relative positions between
two parts. For example, shims inserted into or
under bucket tappets control valve
clearances. Clearance is adjusted by
changing the thickness of the shim.
Slide hammerA special puller that screws
into or hooks onto a component such as a
shaft or bearing; a heavy sliding handle on the
shaft bottoms against the end of the shaft to
knock the component free.SprocketA tooth or projection on the
periphery of a wheel, shaped to engage with a
chain or drivebelt. Commonly used to refer to
the sprocket wheel itself.
Starter inhibitor switchOn vehicles with an
automatic transmission, a switch that
prevents starting if the vehicle is not in Neutral
or Park.
StrutSee MacPherson strut.
TTappetA cylindrical component which
transmits motion from the cam to the valve
stem, either directly or via a pushrod and
rocker arm. Also called a cam follower.
ThermostatA heat-controlled valve that
regulates the flow of coolant between the
cylinder block and the radiator, so maintaining
optimum engine operating temperature. A
thermostat is also used in some air cleaners in
which the temperature is regulated.
Thrust bearingThe bearing in the clutch
assembly that is moved in to the release
levers by clutch pedal action to disengage the
clutch. Also referred to as a release bearing.
Timing beltA toothed belt which drives the
camshaft. Serious engine damage may result
if it breaks in service.
Timing chainA chain which drives the
camshaft.
Toe-inThe amount the front wheels are
closer together at the front than at the rear. On
rear wheel drive vehicles, a slight amount of
toe-in is usually specified to keep the front
wheels running parallel on the road by
offsetting other forces that tend to spread the
wheels apart.
Toe-outThe amount the front wheels are
closer together at the rear than at the front. On
front wheel drive vehicles, a slight amount of
toe-out is usually specified.
ToolsFor full information on choosing and
using tools, refer to the Haynes Automotive
Tools Manual.
TracerA stripe of a second colour applied to
a wire insulator to distinguish that wire from
another one with the same colour insulator.
Tune-upA process of accurate and careful
adjustments and parts replacement to obtain
the best possible engine performance.TurbochargerA centrifugal device, driven by
exhaust gases, that pressurises the intake air.
Normally used to increase the power output
from a given engine displacement, but can
also be used primarily to reduce exhaust
emissions (as on VW’s “Umwelt” Diesel
engine).
UUniversal joint or U-jointA double-pivoted
connection for transmitting power from a
driving to a driven shaft through an angle. A
U-joint consists of two Y-shaped yokes and a
cross-shaped member called the spider.
VValveA device through which the flow of
liquid, gas, vacuum, or loose material in bulk
may be started, stopped, or regulated by a
movable part that opens, shuts, or partially
obstructs one or more ports or passageways.
A valve is also the movable part of such a
device.
Valve clearanceThe clearance between the
valve tip (the end of the valve stem) and the
rocker arm or tappet. The valve clearance is
measured when the valve is closed.
Vernier caliperA precision measuring
instrument that measures inside and outside
dimensions. Not quite as accurate as a
micrometer, but more convenient.
ViscosityThe thickness of a liquid or its
resistance to flow.
VoltA unit for expressing electrical
“pressure” in a circuit. One volt that will
produce a current of one ampere through a
resistance of one ohm.
WWeldingVarious processes used to join metal
items by heating the areas to be joined to a
molten state and fusing them together. For
more information refer to the Haynes
Automotive Welding Manual.
Wiring diagramA drawing portraying the
components and wires in a vehicle’s electrical
system, using standardised symbols. For
more information refer to the Haynes
Automotive Electrical and Electronic Systems
Manual.

3261 Jaguar XJ6
Almost ever y car you’ve ever loved, loathed or desired is gathered under one roof at the Haynes Motor
Museum. Over 300 immaculately presented cars and motorbikes represent ever y aspect of our motoring
heritage, from elegant reminders of bygone days, such as the superb Model J Duesenberg to curiosities like
the bug-eyed BMW Isetta. There are also many old friends and flames. Perhaps you remember the 1959 Ford
Popular that you did your courting in? The magnificent ‘Red Collection’ is a spectacle of classic sports cars
including AC, Alfa Romeo, Austin Healey, Ferrari, Lamborghini, Maserati, MG, Riley, Porsche and Triumph.
A Perfect Day Out
Each and ever y vehicle at the Haynes Motor Museum has played its part in the histor y and culture of
Motoring. Today, they make a wonderful spectacle and a great day out for all the family. Bring the kids, bring
Mum and Dad, but above all bring your camera to capture those golden memories for ever. You will also find
an impressive array of motoring memorabilia, a comfortable 70 seat video cinema and one of the most
extensive transport book shops in Britain. The Pit Stop Cafe serves ever ything from a cup of tea to
wholesome, home-made meals or, if you prefer, you can enjoy the large picnic area nestled in the beautiful
rural surroundings of Somerset.
The Museum is situated on the A359 Yeovil to Frome road at Sparkford, just off the A303 in Somerset. It is about 40 miles south of Bristol, and
25 minutes drive from the M5 intersection at Taunton.
