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.

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.
Removing the engine oil filter using a filter removal tool.

(3) Release the hose clamps and disconnect the
fuel hoses from the filter. Remove the filter from the
retaining clamp noting the direction of the arrow on
the filter body. On some models it will be necessary to remove the
screw from the side of the clamp to allow the filler to
be removed.

Installation is a reversal of the removal procedure
with attention to the following points:

(1) Install the fuel filter with the arrow facing the
direction noted on removal, that is, in the direction of
fuel flow.
(2) Ensure that the hose clamps are tightened
securely.
(3) Connect the fuel pump wiring connector and
install the rear seat cushion. (4) Start the engine and check for fuel leaks.
Rectify as necessary.
TO ADJUST DRIVE BELTS

It is essential that all drive belts are adjusted to
the correct tension to prevent slippage or premature
wear of the bearings in the alternator and, if equipped,
the power steering pump and air conditioner compres-
sor.

(1) Push down on the drive belt with a 10 kg
force midway between the pulleys of the drive belt
concerned.

On models with air conditioning, push down on
the upper section of the drive belt between the
compressor and crankshaft pulleys.

If the drive belt deflection is not within Specifi-
cations it will require adjustment as follows.

(2) Loosen the alternator and, if equipped, the
power steering pump pivot and adjusting bolts and

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.
Cutaway view of spark plug showing a crack in the
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

42 Engine
The cylinder block is a cast iron alloy, deep skirt
design and the crankshaft is supported in the cylinder
block by five precision insert replaceable main bear-
ings. Crankshaft end float is controlled by the flanged
centre main bearing. Connecting rods are I section
forgings equipped with precision insert replaceable big
end bearings. The gudgeon pins are an interference fit
in the connecting rod and a floating fit in the piston.

The cast aluminum pistons are equipped with
two compression rings and one oil control ring.

The twin rotor, involute gear oil pump is mounted
directly to the front face of the cylinder block. The
inner rotor is internally driven by the crankshaft. The
oil pump pressure relief valve is not adjustable, and
consists of a plunger and spring mounted in the oil
pump body.

The pump draws oil through a screen in the sump
and delivers it, via a full flow replaceable oil filter, to
the oil gallery from where it is distributed to the
hydraulic tappets, camshaft and crankshaft bearings
and to the overhead rocker and valve mechanism.
