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.

32
ROADSIDE TROUBLE SHOOTING
CAUTION: To prevent severe electrical shock extreme care must be taken w\
hen
working on or near the electronic ignition system as dangerous high tension voltages
are produced in both the primary and secondary circuits. See the text fo\
r
precautionary notes.

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.

cylinder head gasket.

(2) Crack in the cylinder head or cylinder block:
Repair or renew as necessary.

NOTE; Check the engine for internal leak-
age by withdrawing the dipstick and inspect-
ing for emulsified oil. Run the engine and
check for excessive steam at the exhaust
pipe which would indi cate coolant leakage
into the combustion chamber.

COOLANT LOSS BY OVERFLOW
(1) Overfull system: Drain the excess coolant
from the system.
(2) Faulty radiator cap: Renew the faulty cap.
(3) Blocked radiator core tubes: Clean or renew
the radiator core.

(4) Faulty thermostat: Renew the thermostat.
(5) Coolant foaming due to poor quality anti-
freeze or corrosion inhibitor: Drain the system and
renew the coolant and additive.

Renew the radiator cap if the sealing rubber has
deteriorated.
ENGINE OVERHEATING
(1) Radiator cap defective: Renew the radiator
cap.
(2) Incorrect fuel mixture: Check the fuel system
as described in the Fuel and Engine Management
section. (3) Obstructed air passage through the radiator
core from the front to the rear: Blow the obstruction
from the rear to the front of the radiator core using
compressed air or water pressure. (4) Faulty thermostat: Renew the thermostat.
(5) Incorrect ignition timing: Check and adjust
the ignition timing as described in the Engine Tune-up
section. (6) Incorrect valve timing: Set the valve timing
as described in th e Engine section.
(7) Loss of coolant from the overflow: Check
and rectify as described under the heading Coolant
Loss By Overflow.
(8) Poor circulation: Check and rectify as de-
scribed under the heading Coolant Circulation Faulty.
(9) Low engine oil level: Stop the engine imme-
diately and replenish the oil in the sump. (10) Restricted muffler, catalytic converter or
damaged tailpipe, accompanied by loss of power:
Remove the restrictions or renew the faulty com-
ponents as necessary.
(11) Incorrectly adjusted or dragging brakes:
Check and rectify by adjustment or renewal of
components. (12) Faulty temperature gauge and/or sender unit:
Check and rectify as necessary.
NOTE: Engine overheating is indicated by
an excessive rise in engine temperature
shown by the temperature gauge.

Overheating is usually accompanied by
steam emitting from the coolant overflow
pipe and loss of engine power. A blown
cylinder head gasket may be indicated by
bubbles in the coolant.

COOLANT CIRCULATION FAULTY
(1) Partial blockage of the radiator core tubes:
reverse flush or renew the radiator core.
(2) Sludge deposits in the engine water jacket:
Clean and flush the engine water jacket and add
inhibitor to the coolant. (3) Faulty water pump: Renew the water pump.
(4) Faulty thermostat: Renew the thermostat.
(5) Collapsing lower radiator hose: Renew the
lower radiator hose and check the radiator core tubes. (6) Insufficient coolant in the system: Replenish
the coolant and check for leaks.
NOTE: If rust or sludge deposits are sus-
pected, check the color of the coolant in the
radiator. Rusty or muddy coolant indicates
rust or sludge in the system.
