INTRODUCTION
This Service and Repair Manual
covers the Australian manufac-
tured Nissan Pulsar (hatchback) and Vector (sedan) N13 Series 1
(J87 - 91 and
the Holden Astra LD Series 1987 - 89.
Two engines were available: a 1.8 l i t e r engine with multi-point fuel injec-
tion, and a 1.6 liter throttle body injected engine. The engines are similar
having single overhead camshafts and computer controlled fuel injection and
ignition control. There was a choice of three speed automatic or five speed
manual transaxles.
A viscous coupling limited s l i p differential was introduced from July 1989
to the five speed manual transaxle models of the Pulsar Q and Vector SSS.
Disc brakes are fitted at the front of a l l models, while the rear brakes are
either discs or drums.
All models are equipped with independent coil spring suspension. Steering
can be by either manual or power assisted rack and pinion.
This manual includes information on trouble shooting, lubrication and
maintenance, specifications and the rem oval, installation and overhaul of com-
ponents which are considered to be with in the scope of the average, well
equipped home mechanic.
Certain repair jobs covered in this manual require the use of special
equipment not normally found in a home tool kit. When such equipment is
required, the equipment and i t s functi on is brought to the users attention
underneath the heading for that component. Some jobs, such as automatic
transmission overhaul, should he left to an authorized dealer or a specialist
who has the extensive knowledge and equi pment required. In these cases, the
removal and installation procedures are fully covered, enabling the unit to be
removed for repair or a reconditioned unit to be installed.
Reference in the manual to the left an d right hand sides of the vehicle are
from the point of view of someone sta nding at the back of the vehicle and
looking forward.
Inexperienced operators should not a ttempt a service or repair operation
before completely reading the appropriat e section (or other sections which may
be referred to) in the manual.

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.
Page 11 of 238
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.
Tap and die set and assorted screw extractors.

Special Equipment Required:
To Test Compression — Compression gauge
TO SERVICE AIR CLEANER
The air cleaner is equipped with a paper element.
The element should be regu larly inspected but should
not be cleaned in service.
The element should be renewed every 40 000 km.
This distance is only a guide for normal operating
conditions and should be reduced accordingly if the
vehicle is operating under ex tremely dusty conditions.
NOTE: Paper air cleaner elements should
not be washed in petrol or any other type of

Check the cylinder compressions using a compression gauge.
(a) Inject a small amount of engine oil into the
spark plug hole of the cylinder concerned ensuring
that the oil is evenly distributed within the cylinder by
rotating the engine.
(b) Repeat the compression test on the cylinder
concerned.
A substantial increase of compression pressure
indicates faulty or worn piston rings, pistons or
cylinder.
No increase of compression pressure indicates
burnt, obstructed or sticking valves, or a leaking or
blown cylinder head gasket.
(9) Install the fusible li nk and connect the high
tension lead to the coil.
TO SERVICE THE DISTRIBUTOR
The electronic ignition system requires virtually
no maintenance except for checking of the distributor
cap. rotor and high tension leads as described below.
Refer to the Fuel and Engine Management section
for Specifications and Trouble Shooting.
NOTE: When working on or near electronic
ignition systems, care should be taken as
dangerous high voltages are present in both
the primary and secondary circuits.
The ignition switch should be turned off
before removing or inst alling any electrical
connections otherwise damage to the igni-
tion system as well as severe electrical shock
could result.
TO SERVICE HIGH TENSION LEADS
Check the leads for perishing or cracking and
renew as required. Never a ttempt to repair defective
carbon impregnated core leads.
The lead may be carefully cleaned, using cloth
moistened with kerosene a nd then wiped completely
dry.
If an ohmmeter is available the electrical resis-
tance of the leads may be checked as follows:
View showing the location of the fusible links.
Check the spark plug high tension leads for cracks and
burnt or corroded terminals.
Check the distributor cap for cracks or tracking
between the terminals
.
Page 30 of 238
30 Engine Tune-up
(1) With the distributor cap and leads removed
as an assembly, test one lead at a time, connecting the
meter probes at the spark plug end of the lead and at
the corresponding terminal in side the cap. Resistance
should be less than 15 000 ohms.
(2) If the resistance is more than 15 000 ohms
remove the lead from the distributor cap and check
(he resistance in the lead only. The lead should be
renewed if the resistance is still more than 15 000
ohms. (3) High distributor cap resistance may be due
to corrosion deposits on the cap terminals. These
deposits should be removed with a small scraper or
emery cloth. Check the distributor cap for cracks or tracking
between the high tension terminals on both the inside
and outside of the cap. Renew the cap if cracks or
tracking are evident.
Check the carbon brush in the centre of the
distributor cap for evidence of arcing and renew as
necessary.
Check the condition of the rotor and renew if
arced excessively or cracked.
HOW TO CONNECT ELECTRICAL TEST
EQUIPMENT
NOTE: Some types of tachometers, timing
lights and ignition system analysers are not
compatible with this type of electronic igni-
tion system and may result in incorrect
readings. It is therefore recommended that
the manufacturer of the test equipment be
consulted before using the equipment.
Do not allow the tachometer lead connec-
tor to short to earth as damage to the test
equipment or ignition system may result.
Timing Light
(1) Connect the timing light to the engine fol-
lowing the instrument manufacturers instructions.
NOTE: Do not connect or disconnect the
timing light with the engine running as
voltage surges could damage the alternator.
Do not allow the high tension leads to open
circuit as damage to the ignition system
could result.
(2) Where necessary, connect the power leads of
the timing light to an external power source to prevent
possible transient voltages in the timing light damag-
ing the vehicle alternator.
Tachometer
(1) Ensure that the tachometer is compatible
with the vehicle ignition system. (2) Disconnect the resistor from the tachometer

This section deals with the common causes of
engine failure to start, as inevitably there will come a
time when every driver will experience this problem
and will therefore need to call upon his own resources
to rectify the trouble. Roadside breakdowns other
than engine failure can be identified by reference to
the Trouble Shooting section on the particular com-
ponent affected.
1. TROUBLE SHOOTING
Trouble shooting is only a process of elimination
and provided the procedure is carried out correctly
and systematically an accur ate diagnosis of the trouble
can be made in the minimum amount of time.
For an internal combustion engine to run there
are three basic requirements, these are ignition, fuel
and compression. There are other factors of course
but as a rule an engine's failure to start can be
attributed to a fault in one of these three systems.
Reports from field engineers of motoring organi-
sations prove that the bigg est percentage of engine
breakdowns are in the order of ignition or electrical
failure first, followed by fuel, with mechanical or
compression failure the least common.
Should the engine fail to start, first check that
there is adequate fuel in the tank and if so. carry out
the following checking procedures in the order de-
scribed.
TO JUMP START A VEHICLE
NOTE: Jump starting a vehicle can be
dangerous if the procedure described below
is not performed correctly. If any doubt
exists, it is recommended that the services of
a competent mechanic be obtained.
The vehicles covered by this manual are
equipped with complex electronic circuitry
which can be damaged by voltage surges.
These voltage surges can be generated when
jump starting, or being jump started by
another vehicle. If av ailable use jumper
leads equipped with a surge protection de-
vice and follow the lead manufacturers in-
structions carefully, particularly regarding
the connection and disconnection of the
leads.
(1) Ensure that the booster battery is 12 volts
and the negative terminal is earthed.
(2) Ensure that the vehicles are not touching and
that the ignition and all accessories on both vehicles
are switched Off. (3) Ensure that the transmissions on both vehi-
cles are in Park or Neutral and the handbrakes are
firmly applied. (4) Remove the vent caps from the battery and
check the electrolyte level. Replenish with distilled
water as necessary.
View showing the correct jumper lead connections for
jump starting a vehicle. The leads shown are equipped
with a surge protection device.

Roadside Trouble Shooting
(5) Place the vent caps loosely over the cell
apertures.
(6) Connect one end of the red jumper lead to
the positive ( + ) battery terminal of the booster
battery and the other end of the red lead to the
positive (+) battery terminal of the discharged bat-
tery.
NOTE: The battery emits hydrogen gas
which is explosive. Do not expose the battery
to naked /lames or sparks.
Do not lean over the battery when con-
necting the jumper leads.
Do not allow the ends of the jumper leads
to touch one another or any part of the
engine.
(7) Connect one end of the black juniper lead to
the negative (-) battery terminal of the booster
battery and the other end of the black lead to a good
earthing point on the engine of the vehicle with the
discharged battery.
NOTE: Do not connect the jumper lead
directly to the negative (-) battery terminal
of the discharged battery.
(8) Start the engine on the vehicle with the
booster battery and run the engine at a moderate
speed. (9) Start the engine on the vehicle with the
discharged battery.
(10) If possible, leave the engines of both vehi-
cles running for 10 minutes.
(11) Disconnect the jumper leads in the reverse
order of the sequence in which they were connected.
2. TO CHECK IGNITION AND ELECTRICAL SYSTEM
(1) Switch on the ignition and check for warning
lamp illumination on the dashboard. (2) Operate the starter and check that the starter
rotates the engine at a steady speed.
(3) Switch on the headlamps and check for good
light intensity. Should the lamps not illum inate or the starter
motor not turn the engine, carry out the following
steps:
(a) Remove the battery terminals and clean both
terminals and posts. Connect the terminals and where
applicable tighten firmly but not excessively.
(b) Check that the earth lead from the battery to
the engine or body frame is not broken and that the
connections are clean and secure. . (c) Check that the lead from the battery to the
starter motor or starter solenoid is intact and has a
clean and secure connection.
Ensure that the battery posts and terminals are clean.
(d) Where necessary carry out repairs to (b) and
(c).
Repeat the check procedur e. Should the starter
motor still not operate, or the lamps not illuminate,
