10 General Information
If tools are to be stored for any length of time, it is
good policy to wipe them with an oily cloth.
Bladed screwdrivers should be checked for dam-
age to the tip. If necessary, the tip can be returned to
its original profile by careful grinding. Do not grind
screwdriver tips to a sharp point.
Hammer heads should be secure on their handles
and should be regularly checked for cracking or other
damage.
Chisels and punches should be checked for dam-
age or 'mushrooming' of the head. Any faults should
be rectified by grinding.
Hydraulic jacks should be regularly checked for
fluid leaks. Chassis stands and car ramps should be
checked for damage and cracks. Any equipment that
is suspect should not be used.
STORES
For routine maintenance, stores of automotive
oils, greases and additives should be kept on hand.
The following is a suggested list.
Engine oil.
Brake fluid.
Manual transmission or automatic transmission
oil — automatic transmission oil is also used in
the power steering system.
Rear axle oil.
Cooling system corrosion inhibitor/antifreeze.
Chassis grease.
High melting point grease, for hub bearings etc.
Penetrating oil or spray.
Kerosene or similar cleaning solvent.
Methylated spirits.
Oils and greases are available in handy pack size for
do-it-yourself lube jobs.
2. SAFETY
PERSONAL SAFETY
Safety when working on a motor vehicle is basical-
ly a matter of commonsense. Some safety precautions
to prevent personal in juries are as follows.
Raising a Vehicle
Always jack a vehicle on firm, level ground and at
the specified jacking points . Ensure that the wheels
remaining on the ground are fully chocked.
After raising the vehicle, place chassis stands
underneath and allow the weight of the vehicle to rest
on them. Do not use bricks, blocks of wood or similar
material.
NOTE: Never work under a vehicle which is
only supported by a jack.
Electrical System
Always disconnect the negative battery terminal
when working on any electrical components. Avoid
wearing metal watches, rings and chains which may
short across live terminals.
As battery gases are explosive, keep naked flames
and sparks clear of the work area. When connecting
and disconnecting jumper leads, use extreme caution
to avoid sparking.
Electronic Ignition Systems
Electronic ignition systems produce dangerous
high tension voltages in bo th the primary and second-
ary circuits which can be fatal. Exercise extreme
caution when working on or near any ignition system
components. Do not disconnect high tension leads
while the engine is running.
Work Area
Do not run the engine in a confined space. Ensure
that the work area is adequately ventilated.
Spilt oil or water should be cleaned immediately
to avoid the possibility of slipping.
Fuel System
Always disconnect the negative battery terminal
when working on any fuel components. Do not smoke.
Keep naked flames and sparks clear of the work area.
Do not siphon fuel using the mouth. Use a hand
pump or suitable siphon.
Do not attempt to repair a fuel tank by welding it.
This is an extremely hazardous procedure and should
be entrusted to a specialist.
Cooling System
To avoid scalding, use caution when releasing the
radiator cap on an engine wh ich is at normal operating
temperature. Turn the cap anti-clockwise to the first
stop and allow any pressure in the system to release.
When the pressure is released, remove the cap from
the radiator.
Brakes
As asbestos is used in some brake lining material,
avoid inhaling brake dust. Do not use compressed air
to remove the dust. Gentle brushing with a small
brush or using a vacuum cleaner with a hose attach-
ment are the safest methods of cleaning the brakes.
The above precautions also apply to the clutch plate
lining material.

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
Location of the engine sump drain plug.

switch. When starting the engine, the fuel
pump will not operate until the oil pressure
is sufficient to extinguish the oil pressure
warning lamp. Therefore it will be necessary
to operate the starter motor for a longer
period than usual to start the engine.
(3) If the fuel pump cannot be felt operating,
check the fuel pump fuse located in the fuse panel
adjacent to the steering column.
If the fuel pump fuse is serviceable, refer to the
Fuel and Engine Management section for detailed
tests on the fuel pump.
(4) Check that all fuel hose connections are
secure.
(5) Remove the spark plugs and check for petrol
saturation of the electrodes which indicates flooding.
Thoroughly clean and dry the spark plugs before
replacement. Fully depress the throttle pedal and turn the
ignition switch to the start position. If the engine does
not start, proceed as follows.
Check that the MAP sensor hose is not blocked or split
and ensure that all electrical connections are clean and
secure.
If flooding persists, refer to the Fuel and Engine
Management section.
(6) Check that all EFI electrical wiring connec-
tors are clean and secure.
(7) Check that the MAP sensor vacuum hose is
securely connected at each end and is not split or
blocked.
4. TO CHECK MECHANICAL SYSTEM
The following check procedure assumes that the
starter motor will rotate the engine. If not, on manual
transaxle models, depress the clutch pedal to disen-
gage the engine from the tr ansaxle in case the fault lies
within the transaxle.
If the starter motor will not rotate the engine, it
will be necessary to remove the starter motor and
attempt to turn the engine over manually. This will
establish whether the fault lies with the starter motor,
which could be jammed or defective, or with the
engine, which could be seized or have broken internal
components such as connecting rods, pistons and
crankshafts etc.
If the starter motor is not at fault and the engine
will not rotate manually, refer to the Engine Mechan-
ical Trouble Shooting heading in the Engine section.
It should be noted that the only way that cylinder
compression can be accurately tested is with a com-
pression gauge. The method described in the following
procedure is only intended to give a rough indication
when checking for causes of engine breakdown,
(I) When the engine is cool, check for loss of
coolant from the cooling system.
If coolant loss is evident, check carefully for any
indication of external leakage. Remove the engine oil
dipstick and check for wate r contamination (emulsi-
fication) of the oil. When oil mixes with water it will
Ensure that all fuel connections are securely tightened.

mountings. Lower the assembly onto the mountings
and tighten the mounting nuts and bolts.
(4) Install a new exhaust flange gasket.
(5) Fill the engine and transaxle with the correct
quantity and grade of lubricant. (6) Fill the cooling system as described in the
Cooling and Heating Systems section. (7) On models with power steering, fill the power
steering reservoir with the recommended fluid.
(8) Start and run the engine until it reaches the
normal operating temperatur e and check for fuel, oil
and coolant leaks.

(12) Remove the bolts securing the camshaft
drive belt inner cover to the camshaft housing. (13) Remove the cylinder head bolts in the re-
verse order of the tighten ing sequence, backing off
each bolt a quarter of a turn then half a turn at a time
until the bolts are loose.
NOTE: Do not loosen the cylinder head
bolts while the engine is warm as distortion
of the cylinder head could result.
(14) Remove the cylinder head bolts and lift the
camshaft housing from the cylinder head. (15) The rocker arms, thrust pads and tappet
assemblies can now be removed from the cylinder
head. Number a rack from 1 to 8 and keep each
