When purchasing tools, it is sound advice to select
the highest quality that can be afforded, as the
working life of cheaper tools is often very short.



Assorted measuring devices — inside and outside
micrometers, vernier calipers, wire gauges and feeler
gauges.
Ensure that the tools are suitable for the system of
bolt and nut sizing on the vehicle. The range of
vehicles covered by this manual use metric sizes.

TOOL CARE
To ensure the longest possible life for hand tools,
it is important that time be spent maintaining them.

At the conclusion of each job. all tools used should
be washed thoroughly in kero sene or similar cleaning
solvent. Ensure that all dirt and grease is removed,
particularly from tools with moving parts such as
pliers and adjustable spanners. The tools should then
be wiped dry with a clean cloth.

Measuring devices should be given particular
attention as their accuracy can be affected if not
properly maintained. Feeler gauges should be kept
clean at all ti mes and the blades should be wiped with
an oily cloth after use to prevent rusting.

General Information 11
Lifting Equipment
When using lifting equipment to lift heavy com-
ponents such as the engine and/or transmission, use
metal slings or chain in preference to rope. If rope
must be used, ensure that it is not placed against sharp
edges on the component.

Automotive Lubricants and Solvents
Avoid prolonged skin contact with oils, greases
and solvents as some can cause skin irritations and
dermatitis.

Exercise caution when us ing cleaning solvents as
many are inflammable. Do not smoke. Keep naked
flames and sparks clear of the work area.

Compressed Air
Never point an air hose at another person or allow
compressed air to blow onto your skin. High pressure
air forced against the skin can enter the bloodstream
and prove fatal.

Suspension and Steering Components
Damaged suspension and steering components
should not be welded. Many of these components are
fabricated from toughened metals. If welded they may
lose their strength or become brittle. Damaged com-
ponents should be renewed.

Air Conditioning
Avoid disconnecting air conditioning hoses as
escaping refrigerant can cause frostbite. The refriger-
ant is highly flammable and when burnt, a poisonous
gas is produced.

VEHICLE SAFETY
To prevent damage to the vehicle during servicing
or repair work, note the following precautions.

Brake Fluid
If spilt on the vehicle paintwork, brake fluid
should be immediately washed away with clean water
and allowed to dry naturally, not wiped with a cloth.

Catalytic Converter
The following should be observed to prevent
damage to the catalytic converter:

Do not operate the vehicle on leaded fuel.
Do not push or tow start the vehicle.
Do not allow the engine to idle for prolonged
periods.

Do not switch the ignition off while the vehicle is
in motion and the transmission is in gear.

Do not 'prime' the engine by pouring fuel into the
inlet manifold.

Do not operate the vehicle if the engine is
misfiring.

Avoid running the vehicle out of fuel.
Ensure that the engine oil is formulated to contain
low phosphorus levels.

Electronic Components
The electronic components of the ignition and
fuel injection systems can be damaged by the use of
incorrect testing equipment.

It is essential in all tests where voltage or resis-
tance is to be measured that a digital display multi-
meter with a minimum 10 megohm input impedance
be used.

Some types of tachometers, timing lights and
ignition system analyzers are not compatible with
certain engine electronic systems. It is therefore
recommended that the manufacturer of the test equip-
ment be consulted before using the equipment.

Jump starting, or being jump started by another
vehicle can cause damage to the electronic compon-
ents of the vehicle. Refer to the Roadside Trouble
shooting section for the correct jump starting proce-
dure.

3. GENERAL REPAIR PROCEDURES
SEIZED FASTENERS
Seized bolts, nuts or screws should first have a
liberal amount of penetrating oil applied. The fastener
should be left for a period of time to allow the oil to
penetrate and soften the corrosion which is causing
the binding.

Often, a sharp hammer blow to the head of the
fastener can dislodge the corrosion and permit it to be
loosened.

An impact driver, which can be fitted with a
socket or screwdriver bit, can be used to loosen a
seized fastener.

Another method is to heat the component in
which the fastener is seized. However, extreme cau-
tion should be exercised when heating aluminum
alloy components as the melting point is much lower
than that of steel.

If the above methods fail to free a seized nut,
carefully hacksaw through one side of the nut until it
can be split. Care should be taken that the threads of
the bolt or stud are not damaged.

Should a bolt or stud break below the surface of
the component, it will be necessary to use a screw
extractor to remove the remaining part. Follow the
screw extractor manuf acturers instructions.

1. HOW TO GREASE AND OIL CHANGE
(1) Run the front of the vehicle onto car ramps
and stop the engine. Chock the front wheels. (2) Raise the rear of the vehicle and place
chassis stands under the rear jacking points.
NOTE: It is best if the vehicle is kept as level
as possible to avoi d false readings when
checking the lubricant levels.



(3) Clean around the engine sump drain plug.
(4) Place a drain tin under the engine sump,
remove the engine sump drain plug and allow the
engine sump to completely drain.
NOTE: It is best to drain the engine sump
with the oil at operating temperature. How-
ever, if the oil is hot take care to avoid
scalding.

(5) Check that the sealing gasket on the sump
plug is in a serviceable condition. (6) When the engine sump has completely
drained, install and firmly tighten the sump drain plug.
Wipe around the plug after installation. (7) Place the drain tin under the oil filler,
remove the oil filter using a filter removal tool and
allow the residual engine oil to drain. Smear the
scaling ring of the new filter with engine oil and
lighten the filter by hand as per the instructions
supplied with the new filter.
NOTE: Before installing the new filter, en-
sure that the sealing gasket from the old
filter has not adhered to the filter sealing
surface on the engine.

(8) Remove the level checking plug from the

level with the bottom of the plug hole. Overfilled units
should be drained to the correct level.

If the oil level is low, use an oil gun to fill the
transaxle to the correct level.

When satisfied that the oil level is correct, install
the plug and tighten firmly. Wipe around the plug
after installation.

NOTE: On automatic transaxle vehicles,
refer to the Automatic Transaxle section for
the checking and topping up procedure.

move the alternator or power steering pump as
required until the drive belt concerned has the
specified deflection.

On models with air conditioning, loosen the nut
in the centre of the idler pulley and turn the adjusting
bolt until the drive belt has the specified deflection.

(3) Tighten the alternator or power steering
pump bolts securely and check the belt tension.

On models with air conditioning, tighten the idler
pulley nut securely.

TO SERVICE SPARK PLUGS
The spark plugs should be renewed at intervals of
40 000 km.

Before removing the spark plugs ensure that the
area around each plug is cl ean to prevent foreign
matter entering the cylinder when the plugs are
removed.

Spark plugs removed from an engine in good
mechanical condition should have a light powdery
deposit ranging from light brown to grayish tan in
color. After considerable service the electrodes will
show signs of wear or no rmal burning. Spark plugs
showing a thick black oily deposit indicate an engine
in poor mechanical condition or possibly, that a plug
with too low a heat range has been installed.

Spark plugs showing a white or yellowish deposit
indicate sustained high speed driving or possibly that
plugs with too high a heat range have been installed,
particularly when these deposits are accompanied by
blistering of the porcelain and burning of the elec-
trodes.

If the spark plugs are to be cleaned, use a
sandblasting machine and blow clean with com-
pressed air. Ensure that all traces of abrasive grit are
removed from the spark plug threads and from the
well in the plug body. Carefully open the electrode gap
a little, by bending the side electrode, and lightly file
the electrodes flat with a points file.


Black damp deposits can be caused by excessive oil
consumption or incorrect plug type. Spark plugs in this
condition are usually not firing.

insulator nose which can be caused by exerting pres-
sure against the centre electrode when adjusting the
gap. The other crack shown on the insulator is caused
by tilting the plug spanner.

When plug electrodes are eroded to this degree the
spark can be considered worn out and should be
renewed using a plug of the recommended heat range
.
CRACK

Engine Tune-up
Spark plug with burnt electrodes and white blistered
appearance, possibly due to incorrect plug type, loose
plug or motor running too hot.
NOTE: Never attempt to alter the electrode
gap by bending the centre electrode as
damage to the porcelain insulator will
result.

Before installing any spark plugs measure the gap
between the electrodes, pref erably with clean wire
gauges. If wire gauges are una vailable, use clean feeler
gauges. Move the side electrode towards or away from
the centre electrode to obtain the correct gap-

Screw the plugs into the cylinder head ringer tight,
then use a torque wrench to tighten the plugs lo the
specified torque.



Checking the spark plug electrode gap with a wire
gauge.
NOTE: If a torque wrench is unavailable,
extreme care must be taken when tightening
the spark plugs as over tightening may lead
to stripping of the thread from the cylinder
head. If the plugs are tightened with the
fingers and then taken up an additional 1/4
of a turn with a spark plug wrench, they will
be tight enough.

TO TEST COMPRESSION
(1) With the engine at operating temperature.
disconnect the high tension leads from the spark
plugs.
(2) Ensure that the area around each spark plug
is clean to prevent foreign matter entering the cylin-
ders and remove the spark plugs. (3) Remove the fusible link that is positioned
third from the front of th e fusible link connecting
block, located at the rear of the battery. Disconnect
the coil high tension lead from the coil.
NOTE: Failure to remove the fusible link
can result in an explosion.

(4) Install a compression gauge to number one
spark hole according to the gauge manufacturers
instructions. (5) Have an assistant fully open the throttle and
operate the starter switch to rotate the engine. Ob-
serve the compression gauge and stop the engine when
the gauge has reached the highest reading, usually
after 3 or 4 compression strokes.
(6) Record the reading a nd check the compres-
sion of the remaining cylinders in the same manner.
(7) Compare all the readings taken. Variation
between the highest and lowest reading cylinders
should not exceed 100 kPa. (8) If a low reading is recorded on one or more
cylinders the trouble may be isolated as follows :

Lightly file the plug electrodes flat with a points file
