DESCRIPTION AND OPERATION
drowsiness. In extreme cases, loss of
consciousness may result. Long term exposure to
vapor concentrations may result in adverse health
effects.
Prolonged contact with the skin may have a
defatting effect which may lead to skin irritation
and in some cases, dermatitis.
Splashes entering the eye will cause discomfort
and possible damage.
Any spraying should preferably be carried out in
exhaust ventilated booths, removing vapors and
spray droplets from the breathing zone.
Wear appropriate gloves, eye and respiratory
protection. Asbestos dust
waste should be dampened, placed
in a sealed container and marked for safe disposal.
If any cutting or drilling is attempted on materials
(
containing asbestos the item should be dampened "
and only hand tools or low speed power tools used.
Battery Acids
See also Acids and Alkalis.
Gases released during charging are explosive.
Never use naked flames or allow sparks near
charging or recently charged batteries.
Make sure there is adequate ventilation.
Brake and Clutch Linings and Pads
Antifreeze
See Asbestos.
See also Fire, Solvents.
For example isopropanol, ethylene glycol,
methanol.
Highly flammable, flammable, combustible.
Used in vehicle coolant systems, brake air pressure
systems, screenwash solutions.
Vapors may be given off from coolant antifreeze
(glycol) when heated. Avoid breathing these
vapors.
Antifreeze may be absorbed through the skin in
toxic or harmful quantities. Antifreeze, if swallowed,
can be fatal and MEDICAL ATTENTION SHOULD
BE SOUGHT IMMEDIATELY.
These products must not be used in any cooling
or industrial water system that is connected or
linked to general, food preparation or drinking water
supplies.
Asbestos
See also Warning Symbols on Vehicles at the end
of this subsection.
Breathing asbestos dust may cause lung damage
or, in some cases, cancer.
Used in brake and clutch linings, transmission
brake bands and gaskets.
The use of drum cleaning units, vacuum cleaning
or damp wiping is preferred.
Brake Fluids (Polyal kylene Glycols)
See also Fire.
Splashes to the skin and eyes are slightly irritating.
Avoid skin and
eye'contact as far as possible.
Inhalation vapor hazards do not arise at ambient
temperatures because of the very low vapor
pressure.
Brazing
See Welding.
Chemical Materials
See also Legal Aspects.
Chemical materials such as solvents, sealers,
adhesives, paints, resin foams, battery acids,
antifreeze, brake fluids, fuels, oils and grease
should always be used with caution and stored and
handled with care. They may be toxic, harmful,
corrosive, irritant or highly flammable and give rise
to hazardous fumes and dusts.
The effects of excessive exposure to chemicals may be immediate or delayed; briefly experienced
or permanent; cumulative; superficial; life
threatening; or may reduce life expectancy.

DESCRIPTION AND OPERATION
Gross or prolonged skin contact with high boiling
point gas oils may also cause serious skin
disorders including skin cancer.
Kerosene (Paraffin)
Used also as heating fuel, solvent and cleaning
agent.
Flammable
- observe No Smoking policy.
Irritation of the mouth and throat may result from
swallowing. The main hazard from swallowing
arises if liquid aspiration into the lungs occurs.
Liquid contact dries the skin and can cause
irritation or dermatitis. Splashes in the eye may be
slightly irritating.
In normal circumstances the low volatility does not
give rise to harmful vapors. Exposure to mists and
vapors from kerosene at elevated temperature
should be avoided (mists may arise in dewaxing).
Avoid skin and eye contact and make sure there
is adequate ventilation.
Alternative Fuel
Highly flammable. Observe "NO SMOKING" signs.
Make sure there is adequate ventilation when
working on alternative fuelled vehicles. Great care
must be taken to avoid the serious consequences
of inhalation in the event of vapor build up in
confined spaces.
Inhalation in high concentrations may cause
dizziness, headache, nausea and loss of
co-ordination. Very high concentrations may result
in loss of consciousness.
Contact with liquefied petroleum gas (LPG) or
compressed natural gas (CNG) to the skin may
cause cold burns and frost bite.
Long sleeved cotton overalls, steel toe capped
safety boots and rubber neoprene gloves should
be worn during removal and installation of
LPGICNG fuel system components.
LPGICNG fuel leaks could cause a fire and be a
hazard to health that can lead to personal injury,
illness or even death.
If a leak is detected, under no circumstances
attempt to seal the leak by tightening the
unionlconnection until the fuel in the system or
component is depressurized. Once tightened the
system should be checked for integrity following
the specified procedures. If
the fuel tank is to be removed for service or repair
the fuel must be evacuated using dedicated
equipment and following the specified
procedures. (
Gas Cylinders
See also Fire.
Gases such as oxygen, acetylene, argon and
propane are normally stored in cylinders at
pressures of up to
138 bar (2000 psi) and great
care should be taken in handling these cylinders
to avoid mechanical damage to them or to the valve
gear attached. The contents of each cylinder
should be clearly identified by appropriate
markings.
Cylinders should be stored in well-ventilated
enclosures, and protected from ice and snow, or
direct sunlight. Fuel gases, for example acetylene
and propane, should not be stored in close
proximity to oxygen cylinders.
Care should be exercised to prevent leaks from
gas cylinders and lines, and to avoid sources of
ignition.
Only trained personnel should undertake work
involving gas cylinders.
Gases
See Gas Cylinders.
Gaskets (Fluoroelastomer)
See Viton.
General Workshop Tools and
Equipment
It is essential that all tools and equipment are
maintained in good condition and that the correct
safety equipment is used where required.
Never use tools or equipment for any purpose other
than that for which they were designed. Never
overload equipment such as hoists, jacks, axle and
chassis stands or
lifting slings. Damage caused by
overloading is not always immediately apparent
and may result in a fatal failure the next time that
the equipment is used.

DESCRIPTION AND OPERATION
Do not use damaged or defective tools or
equipment, particularly high-speed equipment such
i as grinding wheels. A damaged grinding wheel can
disintegrate without warning and cause serious
injury.
Wear suitable eye protection when using grinding,
chiseling or sand blasting equipment.
Wear a suitable breathing mask when using
abrasive blasting equipment, working with
asbestos-based materials or using spraying
equipment.
Make sure there is adequate ventilation to control
dusts, mists and fumes.
High Pressure Air, Lubrication and Oil
Test Equipment
See also Lubricants and Greases.
Always keep high-pressure equipment in good
condition, and regularly maintained, particularly at
joints and unions.
Never direct a high-pressure nozzle, for example
diesel injector, at the skin as the fluid may
, penetrate to the underlying tissue, and cause
serious injury.
Halon
See CFCs.
Legal Aspects
There are many laws and regulations relating to
health and safety in the use and disposal of
materials and equipment in a workshop.
For a safe working environment and to avoid
environmental pollution, workshops should be
familiar, in detail, with the many health and safety
laws and regulations within their country, published
by both national and local authorities.
Lubricants and Greases
Avoid all prolonged and repeated contact with
mineral oils. All lubricants and greases may be
irritating to the eyes and skin.
'
Transmission Fluids
Safety instructions
Certain Transmission and Power Steering fluids
supplied to Ford may contain additives which have
the potential to cause skin disease (dermatitis) to
exposed persons. The dermatitis may be irritant
or allergic in nature. Risks are higher where
prolonged or repeated skin contact with a fluid may
occur. These fluids are used for vehicle initial
fill
and service purposes. This sub-section is to:
Inform Service personnel who may come into
contact with these vehicle fluids (hazard
communication).
Summarise appropriate workplace control
measures and personal protective equipment
requirements.
Draw attention to the existence of Material
Safety Datasheets (MSDS's) for the fluids
(available from Ford Customer Service Division).
These MSDS's contain detailed information on
hazards and appropriate controls.
Control measures
Workplace risk assessments made under national
chemical control regulations should identify
operations involving the fluids as potentially
hazardous and specify workplace control and
worker awareness measures. In such
circumstances, the relevant Material Safety
Datasheet (see the details specified below) which
specifies hazards and control measures in detail
should be made available for guidance.
Avoid unprotected skin contact with the fluids, and
in particular, avoid prolonged or repeated skin
contact. Work practices should be organised so as
to minimise the potential for skin contact. This may
include the use of drip trays, absorbents, correct
fluid handling equipment (funnels etc), and
workplace housekeeping measures such as the
cleaning of contaminated surfaces.
Personnel engaged in operations where skin
contact could occur (such as fluid draining or filling)
should wear impervious gloves made from
nitrile
rubber, certified to a chemical protection standard,
e.g. Europe Standard EN374. This glove type is
widely available from reputable suppliers of gloves
for chemical protection [including the manufacturers
Ansell-Admont
(Solvex Range), North Safety
products (North
Nitrile Latex Gloves range), and

General Information
DESCRIPTION AND OPERATION
Two Pack
Can also contain harmful and toxic unreacted
resins and resin hardening agents. The
manufacturers instructions should be followed. See
also Resin-based Adhesives and
Isocyanate
Adhesives and Sealers under Adhesives and
Sealers.
Spraying should preferably be carried out in
exhausted ventilated booths removing vapor and
spray mists from the breathing zone. Individuals
working in booths should wear appropriate
respiratory protection. Those doing small-scale
repair work in the open workshop should wear
air-fed respirators.
Pressurized Equipment
See High Pressure Air, Lubrication and Oil Test
Equipment.
Solder
Solders are mixtures of metals such that the
melting point of the mixture is below that of the
constituent metals (normally lead and tin). Solder
application does not normally give rise to toxic lead
fumes, provided a
gaslair flame is used.
Oxy-acetylene flames should not be used, as they
are much hotter and will cause lead fumes to be
produced.
Some fumes may be produced by the application
of any flame to surfaces coated with grease, and
inhalation of these should be avoided.
Removal of excess solder should be undertaken
with care, to make sure that fine lead dust is not
produced, which can give toxic effects if inhaled.
Respiratory protection may be necessary.
Solder spillage and filings should be collected and
removed promptly to prevent general air
contamination by lead.
High standards of personal hygiene are necessary
in order to avoid ingestion of lead or inhalation of
solder dust from clothing.
Solvents
See also Chemical Materials, Fuels (Kerosene),
Fire.
For example acetone, white spirit, toluene, xylene,
trichloroethane.
2006.0 Fiesta 1212006
Used in cleaning and dewaxing materials, paints,
plastics, resins and thinners.
Some may be highly flammable or flammable.
Skin contact will degrease the skin and may result
in irritation and dermatitis following repeated or
prolonged contact. Some can be absorbed through
the skin in toxic or harmful quantities.
Splashes in the eye may cause severe irritation
and could lead to loss of vision.
Brief exposure of high concentrations of vapors or
mists will cause eye and throat irritation,
drowsiness, dizziness, headaches and, in the worst
circumstances, unconsciousness.
Repeated or prolonged exposure to excessive but
lower concentrations of vapors or mists, for which
there might not be adequate warning indications,
can cause more serious toxic or harmful effects.
Aspiration into the lungs, for example through
vomiting, is the most serious consequence of
swallowing.
Avoid splashes to the skin, eyes and clothing. Wear
protective gloves, goggles and clothing if
necessary.
Make sure there is good ventilation when in use,
avoid breathing fumes, vapors and spray mists and
keep containers tightly sealed. Do not use in
confined spaces.
When spraying materials containing solvents, for
example paints, adhesive, coatings, use extraction
ventilation or personal respiratory protection in the
absence of adequate general ventilation.
Do not apply heat or flame except under specific
and detailed manufacturers instructions.
Sound Insulation
See Fibre Insulation, Foams.
Suspended Loads
A CAUTI0N:Never improvise lifting tackle.
There is always a danger when loads are lifted or
suspended. Never work under an unsupported,
suspended or raised load, for example a
suspended engine.
Always make sure that lifting equipment such as
jacks, hoists, axle stands and slings are adequate
and suitable for the job, in good condition and
regularly maintained.

DESCRIPTION AND OPERATION
RoadIRoller Testing
I Road or roller testing may be carried out for various
reasons and a procedure detailing pre-test checks,
engine starting and stopping, pre-driving checks,
on-test checks and final checks to be completed
on completion of the test is given below.
Unless complete vehicle performance is being
checked, the full road test procedure need not be
carried out. Instead, those items particularly
relevant to the
system(s) being checked can be
extracted.
Pre-Test Checks
A WARNING:lf the brake system hydraulic
fluid level is low, pedal travel is excessive
or a hydraulic leak is found, do not attempt
to road test the vehicle until the reason for
the low fluid level, excessive pedal travel
or hydraulic leak is found and rectified.
It is suggested that pre-test checks and functional
tests of those systems and circuits which affect the
safe and legal operations of the vehicle, such as
( , brakes, lights and steering, should always be
carried out before the road or roller test.
With the ignition switched off, check:
- the engine oil level.
- the engine coolant level.
- the tires, for correct pressure, compatible types
and tread patterns, and wear within limits.
- that there is sufficient fuel in the tank to
complete the test.
- all around the engine, transmission and under
the vehicle for oil, coolant, hydraulic and fuel
leaks. Make a note of any apparent leaks and
wipe off the surrounding areas to make it easier
to identify the extent of the leak on completion
of the test.
Starting the Engine
N0TE:On initial drive away from cold and within
the first 1.5 km (1 mile), do not depress the
accelerator pedal beyond half travel until the
vehicle has attained a minimum speed of
25 kmlh
(15 mileslh). Never operate at high engine speed
or with the accelerator pedal at full travel whilst the
engine is cold.
With the ignition switched off, check:
- that the parking brake is applied.
- that the gear lever is in the neutral position.
- that all instrument gauges (except fuel gauge)
read zero.
With the ignition switched on, check:
- that the ignition controlled warning lamps are
illuminated.
- that the engine temperature gauge registers a reading compatible with the engine temperature.
- that the fuel gauge registers a reading
appropriate to the fuel level in the tank.
- the operation of the parking brake warning lamp
and fluid level warning indicator.
Road or Roller Testing
A CAUTI0N:lf road testing, check the brake
operation while still traveling at low speed
before continuing with the test. If the
brakes pull to one side, or appear to be
otherwise faulty, do not continue with the
road test until the fault has been found and
rectified.
During the road or roller test, check:
- that the clutch pedal operation is not stiff or
heavy.
- that the initial gear engagement is smooth and
there is no evidence of clutch drag.
- that the parking brake control operates smoothly
and releases quickly and completely.
- that the clutch takes up the drive smoothly,
without slip or judder.
- that gear changing is smooth with no abnormal
noises or vibrations from the transmission.
- the engine power output is satisfactory, full
power is achieved, acceleration is smooth and
pedal operation is not stiff or heavy, and engine
speed returns to idle correctly.
- there is no excessive or abnormally colored
smoke from the engine under normal driving,
heavy load or overrun conditions.
- that steering operation, including power steering
(if equipped), is smooth, accurate, not
excessively heavy or with excessive free play
or vibration.
- that the steering does not pull to one side and
self centers smoothly after cornering.

Brake Testing
A WARNING:When brake testing, avoid
breathing the fumes from hot brakes, this
may contain asbestos dust which is
hazardous to health. Failure to follow this
instruction may result in personal injury.
For additional information, refer to: Health
and Safety Precautions
(1 00-00 General
Information, Description and Operation).
CAUTIONS:
A Avoid brake testing on busy roads where
it may cause inconvenience or danger to
other road users.
A Brake testing which includes heavy brake
applications should not be carried out with
new brake
padsldiscs or liningsldrums
until the components have bedded-in. New
brake friction components will not reach
full efficiency until the bedding-in process
is complete.
Test the brakes at several speeds within the normal
operating range using both light and heavy pedal
pressure. Note any tendency to snatch, pull or
drag, and any undue delay in application or
release.
Allow the vehicle to coast and note any tendency
to pull to one side, or evidence that the brakes are
binding.
After stopping the vehicle (not immediately after a
period of heavy braking), carefully check the brake
temperature.
A brake disc or brake drum that feels
hot or is appreciably hotter than the others,
indicates that the brake is binding.
After completion of the test, check for:

Principles of Operation
The steering wheel rotational movement is
transferred to the steering gear through the steering
column shaft. The steering gear converts this
rotational movement, through the action of the rack
and pinion gear into lateral movement. This
movement in turn is transferred to the wheel
knuckles through the tie-rods and tie-rod ends.
Hydraulic fluid under pressure is supplied to the
steering gear by the power steering pump. As the
steering wheel is rotated, the hydraulic fluid is
allowed to pass through the steering gear valve to
one side of a double acting piston, dependent on
which direction the steering wheel is rotated. The
fluid moves the piston, which forms part of the
steering gear, giving power assistance to the effort
required to rotate the steering wheel.
Vehicles with petrol engines, due to the extra load
on the engine imposed by the power steering
pump, have a power steering pressure (PSP)
switch. The switch, which is normally closed, sends a signal
to the powertrain control module (PCM)
during low speed parking manoeuvres. The PCM
responds by maintaining the engine idle speed.
lnspection and Verification
1. Verify the customer concern.

303-00-5 Engine System - General Information 303-00-5
DIAGNOSIS AND TESTING
Symptom
Oil consumption
Possible Sources Action
Use of the wrong type of
engine oil.
Faulty positive crankcase vent-
ilation (PCV) system.
- Hoses or ventilation or
breather valves are blocked.
This causes excessive
pressure in the crankcase
which causes more oil to
enter the combustion
chamber.
- PCV oil separator is faulty
and engine oil can enter the
combustion chamber
through the intake manifold.
Turbocharger seals (diesel
engine only).
DETERMINE the last type of
engine oil used and compare
with the specification. Change
the engine oil to the specifica-
tion.
CHECK if the PCV system is
operating correctly and repair
as necessary. REFER to:
