12Refitting is a reversal of removal, noting
that the rotor arm can only be fitted in one
position. If necessary, turn the metal rotor hub
so that the screw holes align with those in the
rotor arm and the end of the camshaft. Ensure
that the HT leads are correctly reconnected.

NV and 16 SV
Removal
1Disconnect the battery negative lead.
2Remove the distributor cap, as described in
Section 17.
3Disconnect the distributor wiring plug (see
illustrations).
4On 14 NV models, disconnect the vacuum
pipe from the diaphragm unit on the side of
the distributor.
5If the original distributor is to be refitted,
make alignment marks between the
distributor body and the camshaft housing, sothat the distributor can be refitted in its
original position.
6Turn the crankshaft. This can be done by
either using a socket or spanner on the
crankshaft pulley bolt, or by engaging top
gear and pushing the vehicle backwards or
forwards. Bring No 1 cylinder to the firing
point. No 1 cylinder is at the firing point when:
a)The relevant timing marks are aligned. On
14 NV models, the pointer on the rear
timing belt cover should be aligned
halfway between the two notches in the
crankshaft pulley. On 16 NV models, the
pointer on the rear timing belt cover
should be aligned with the notch in the
crankshaft pulley
b)The tip of the rotor arm is pointing to the
position occupied by the No 1 cylinder HT
lead terminal in the distributor cap
c)On the Bosch distributor, the rotor arm is
aligned with the notch in the distributorbody (remove the rotor arm and plastic
shield, then refit the rotor arm to check
the alignment with the notch). On the
Lucas distributor, the rotor arm is
approximately aligned with the TDC arrow
stamped in the distributor body (see
illustration).
7Unscrew the clamp nut and remove the
clamp plate, then withdraw the distributor
from the camshaft housing (see illustrations).
8If desired, the distributor can be
dismantled, as described in Section 20.
9Check the condition of the O-ring on the
rear of the distributor body, and renew if
necessary.
Refitting
10Begin refitting by checking that No 1
cylinder is still at the firing point. The relevant
timing marks should be aligned. If the engine
has been turned whilst the distributor has

wax-based underbody protective coating, it is
a good idea to have the whole of the
underframe of the vehicle steam cleaned,
engine compartment included, so that a
thorough inspection can be carried out to see
what minor repairs and renovations are
necessary. Steam cleaning is available at
many garages and is necessary for removal of
the accumulation of oily grime that sometimes
is allowed to become thick in certain areas.
The dirt can then be simply hosed off. Note
that these methods should not be used on
vehicles with wax-based underbody
protective coating or the coating will be
removed. Such vehicles should be inspected
annually, preferably just before winter, when
the underbody should be washed down and
any damage to the wax coating repaired.
Ideally, a completely fresh coat should be
applied. It would also be worth considering
the use of such wax-based protection for
injection into door panels, sills, box sections,
etc., as an additional safeguard against rust
damage where such protection is not
provided by the vehicle manufacturer.
After washing paintwork, wipe off with a
chamois leather to give an unspotted clear
finish. A coat of clear protective wax polish,
will give added protection against chemical
pollutants in the air. If the paintwork sheen
has dulled or oxidised, use a cleaner/polisher
combination to restore the brilliance of the
shine. This requires a little effort, but such
dulling is usually caused because regular
washing has been neglected. Care needs to
be taken with metallic paintwork, as special
non-abrasive cleaner/polisher is required to
avoid damage to the finish.
Always check that the door and ventilator
opening drain holes and pipes are completely
clear so that water can be drained out. Bright
work should be treated in the same way as
paint work. Windscreens and windows can be
kept clear of the smeary film that often
appears, by using a glass cleaner. Never use
any form of wax or other body or chromium
polish on glass.
3Upholstery and carpets -
maintenance
1
Mats and carpets should be brushed or
vacuum cleaned regularly to keep them free of
grit. If they are badly stained remove them
from the vehicle for scrubbing or sponging
and make quite sure they are dry before
refitting. Seats and interior trim panels can be
kept clean by wiping with a damp cloth. If they
do become stained (which can be more
apparent on light coloured upholstery) use a
little liquid detergent and a soft nail brush to
scour the grime out of the grain of the
material. Do not forget to keep the headlining
clean in the same way as the upholstery.
When using liquid cleaners inside the vehicle
do not over-wet the surfaces being cleaned.Excessive damp could get into the seams and
padded interior causing stains, offensive
odours or even rot. If the inside of the vehicle
gets wet accidentally it is worthwhile taking
some trouble to dry it out properly, particularly
where carpets are involved. Do not leave oil or
electric heaters inside the vehicle for this
purpose.
4Minor body damage - repair
3
Repairs of minor scratches in
bodywork
If the scratch is very superficial, and does
not penetrate to the metal of the bodywork,
repair is very simple. Lightly rub the area of
the scratch with a paintwork renovator, to
remove loose paint from the scratch and to
clear the surrounding bodywork of wax polish.
Rinse the area with clean water.
Apply touch-up paint to the scratch using a
fine paint brush; continue to apply fine layers
of paint until the surface of the paint in the
scratch is level with the surrounding
paintwork. Allow the new paint at least two
weeks to harden: then blend it into the
surrounding paintwork by rubbing the scratch
area with a paintwork renovator or a very fine
cutting paste and apply wax polish.
Where the scratch has penetrated right
through to the metal of the bodywork, causing
the metal to rust, a different repair technique
is required. Remove any loose rust from the
bottom of the scratch with a penknife, then
apply rust inhibiting paint, to prevent the
formation of rust in the future. Using a rubber
or nylon applicator fill the scratch with
bodystopper paste. If required, this paste can
be mixed with cellulose thinners to provide a
very thin paste that is ideal for filling narrow
scratches. Before the stopper-paste in the
scratch hardens, wrap a piece of smooth
cotton rag around the top of a finger. Dip the
finger in cellulose thinners and then quickly
sweep it across the surface of the
stopper-paste in the scratch; this will ensure
that the surface of the stopper-paste is
slightly hollowed. The scratch can now be
painted over as described earlier in this
Section.
Repair of dents in bodywork
When deep denting of the vehicle’s
bodywork has taken place, the first task is to
pull the dent out, until the affected bodywork
almost attains its original shape. There is little
point in trying to restore the original shape
completely, as the metal in the damaged area
will have stretched on impact and cannot be
reshaped fully to its original contour. It is
better to bring the level of the dent up to a
point that is about 8 in (3 mm) below the level
of the surrounding bodywork. In cases where
the dent is very shallow anyway, it is not worthtrying to pull it out at all. If the underside of the
dent is accessible, it can be hammered out
gently from behind, using a mallet with a
wooden or plastic head. Whilst doing this,
hold a block of wood firmly against the
outside of the panel to absorb the impact
from the hammer blows and thus prevent a
large area of the bodywork from being
“belled-out”.
Should the dent be in a section of the
bodywork that has a double skin or some
other factor making it inaccessible from
behind, a different technique is called for. Drill
several small holes through the metal inside
the area particularly in the deeper section.
Then screw long self-tapping screws into the
holes just sufficiently for them to gain a good
purchase in the metal. Now the dent can be
pulled out by pulling on the protruding heads
of the screws with a pair of pliers.
The next stage of the repair is the removal
of the paint from the damaged area, and from
an inch or so of the surrounding “sound”
bodywork. This is accomplished most easily
by using a wire brush or abrasive pad on a
power drill, although it can be done just as
effectively by hand using sheets of abrasive
paper. To complete the preparation for filling,
score the surface of the bare metal with a
screwdriver or the tang of a file, or
alternatively, drill small holes in the affected
area. This will provide a good “key” for the
filler paste.
To complete the repair see the Section on
filling and re-spraying.
Repair of rust holes or gashes in
bodywork
Remove all paint from the affected area and
from an inch or so of the surrounding “sound”
bodywork, using an abrasive pad or a wire
brush on a power drill. If these are not
available a few sheets of abrasive paper will
do the job just as effectively. With the paint
removed you will be able to gauge the severity
of the corrosion and therefore decide whether
to renew the whole panel (if this is possible) or
to repair the affected area. New body panels
are not as expensive as most people think
and it is often quicker and more satisfactory
to fit a new panel than to attempt to repair
large areas of corrosion.
Remove all fittings from the affected area
except those which will act as a guide to the
original shape of the damaged bodywork (e.g.
headlamp shells, etc.). Then, using tin snips or
a hacksaw blade, remove all loose metal and
any other metal badly affected by corrosion.
Hammer the edges of the hole inwards to
create a slight depression for the filler paste.
Wire brush the affected area to remove the
powdery rust from the surface of the
remaining metal. Paint the affected area with
rust inhibiting paint. If the back of the rusted
area is accessible treat this also.
Before filling can take place it will be
necessary to block the hole in some way. This
can be achieved by using aluminium or plastic
mesh, or aluminium tape.
11•2Bodywork and fittings
to be refitted, tie a length of string to the end
of the wiring. Then feed the wiring through the
boot lid and untie the string, leaving it in
position in the boot lid to assist refitting.
3Mark the position of the hinges on the boot
lid.
4With the help of an assistant, support the
weight of the boot lid, then unscrew the
securing bolts from the hinges, and lift the
boot lid from the vehicle. If the boot lid is to be
refitted, rest it carefully on rags or cardboard,
to avoid damaging the paint.
5If a new boot lid is to be fitted, transfer all
the serviceable fittings (rubber buffers, lock
mechanism, etc.), to it.
6If desired, the boot lid hinge counter-
balance springs can be removed, but before
unhooking them from the vehicle body, note
their position so that they can be refitted in
their original positions (see illustration). Use
a lever to unhook the springs.
Refitting
7Refitting is a reversal of removal,
remembering the following points.
8Align the hinges with the precisely made
marks on the boot lid.
9Where applicable, draw the central locking
solenoid wiring through the boot lid, using the
string.
10If necessary, adjust the hinge bolts and
the rubber buffer until a good fit is obtained
with the boot lid shut.
11If necessary, adjust the position of the
lock striker on the body, to achieve
satisfactory lock operation.

string to the ends of all the relevant wires, and
if necessary the washer fluid hose, then feed
the wiring and the hose through the top edge
of the tailgate. Untie the string, leaving it in
position in the tailgate to assist refitting.
6Prise off the rear roof trim panel, taking care
not to break the securing clips, and lower the
rear of the headlining slightly for access to the
tailgate hinge securing screws (see
illustrations). Mark the hinge positions on the
body.
7Have an assistant support the weight of the
tailgate, then disconnect the tailgate struts
from their mounting balljoints, with reference
to Section 15.
8Ensure that the tailgate is adequately
supported, then remove the hinge securing
screws and withdraw the tailgate from the
vehicle. If the tailgate is to be refitted, rest it
carefully on rags or cardboard, to avoid
damaging the paint.
9If desired, the hinges can be removed from
the tailgate by driving out the hinge pins.
10If the tailgate can be moved up and down
on its hinges due to wear in the hinge pins or
their holes, it may be possible to drill out the
holes and fit slightly oversize pins. Consult a
Vauxhall dealer for further advice.
11If a new tailgate is to be fitted, transfer all
