Removal
1Disconnect the battery negative lead.
2Prise the plastic surround from the door
interior handle.
3Free the trim panel from the top edge of the
door by releasing the securing clips. This can
be done using a screwdriver, but it is
preferable to use a forked tool, to minimise
the possibility of damage to the trim panel and
the clips.
4Note the position of the mirror switch wiring
connector in the bracket at the top of the
door, then separate the two halves of the
connector.
5Prise the switch from the door trim panel,
and feed the wiring through the panel.

14Oil pressure warning lamp
switch - removal and refitting
3
Removal
1Disconnect the battery negative lead.
2The switch is screwed into the oil pump, on
the inlet manifold side of the engine. On 1.4
and 1.6 litre (except C16 NZ2), models the
switch projects at right-angles to the
crankshaft axis, while on C16 NZ2, 1.8 and
2.0 litre models it is parallel to the crankshaft
(see illustration).
3In most cases the switch can be reached
quite easily from above. However, on some
models access will be easier if the front of the
vehicle is jacked up and supported on axle
stands (see “Jacking and Vehicle Support”)
(ensure that the handbrake is securely
applied) and the front right-hand roadwheel is
removed.
4Disconnect the switch wire and use a
spanner to unscrew the switch (see
illustration). As you withdraw the switch,
swiftly plug the hole in the oil pump to
minimise the loss of oil and to prevent the
entry of dirt.
Refitting
5Refitting is the reverse of the removal
procedure; tighten the switch securely but do
not overtighten it, reconnect its wire, then
check and if necessary top-up the oil level, as
described in Chapter 1. Wash off any spilt oil
and check for leaks when the engine is
restarted.

55Airbag - general
All 1993 Cavalier models are available with
an airbag that is designed to prevent serious
chest and head injuries to the driver during an
accident. A similar bag for the front seat
passenger is also available on certain models.
Sensors in the centre of the car measure the
vehicle deceleration rate and pass these
signals to a microprocessor. This unit
analyses the sensor data and compares the
information with pre-programmed values
stored in its memory, triggering the airbag if
the deceleration is severe. The airbag is
inflated in 50 milliseconds by a gas generator
that forces the bag out of the module cover in
the centre of the steering wheel.
No repairs are possible on the airbag unit or
its associated parts. The contents of the
following Sections are confined to removal
and refitting of the airbag, purely for access to
other non-related components.
Should a fault be suspected on the airbag
unit, indicated by the warning light on the
instrument panel, or if the car has been
involved in an accident, however minor,
consult a Vauxhall dealer immediately. Do not
attempt to dismantle any of the airbag
components or carry out any work
whatsoever, other than the procedures
described in the following Sections.
On vehicles fitted with a passenger side
airbag, do notfit accessories in the airbag
zone. Items like telephones, cassette storage
boxes, additional mirrors, etc., can be ripped off
and cause serious injury, if the airbag inflates.

Warning: Before starting any
work on airbag or related
components, disconnect the
battery. Cover the battery’s
terminals and wait a minimum of 1
minutes as a precaution against
accidental firing of the airbag unit. This
period ensures that any stored energy in
the back-up capacitor is dissipated.
Handle the airbag unit with extreme care
as a precaution against personal injury,
and always hold it with the cover facing
away from the body. If in doubt
concerning any proposed work involving
the airbag unit or its control circuitry,
consult a Vauxhall dealer or other
qualified specialist.

1 General description
The bodyshell and floorpan are of pressed
steel, and form an integral part of the vehicle’s
structure, without the need for a separate
chassis.
Various areas are strengthened, to provide
for suspension, steering and engine mounting
points, and load distribution.
Extensive corrosion protection is applied to
all new vehicles. Various anti-corrosion
preparations are used, including galvanising
and PVC under-sealing. Protective wax is
injected into the box sections and other
hollow cavities.
Extensive use is made of plastic for
peripheral components, such as the radiator
grille, bumpers and wheel trims, and for much
of the interior trim.Interior fittings are to a high standard on all
models, and a wide range of optional
equipment is available throughout the range.
Except for the rear quarter windows, all
fixed glass is bonded in position, using a
special adhesive. Any work in this area should
be entrusted to a Vauxhall dealer or glass
replacement specialist.
2 Bodywork and underframe -
maintenance
1
The general condition of a vehicle’s
bodywork is the one thing that significantly
affects its value. Maintenance is easy but
needs to be regular. Neglect, particularly after
minor damage, can lead quickly to further
deterioration and costly repair bills. It is
important also to keep watch on those partsof the vehicle not immediately visible, for
instance the underside, inside all the wheel
arches and the lower part of the engine
compartment.
The basic maintenance routine for the
bodywork is washing preferably with a lot of
water, from a hose. This will remove all the
loose solids that may have stuck to the
vehicle. It is important to flush these off in
such a way as to prevent grit from scratching
the finish. The wheel arches and underframe
need washing in the same way to remove any
accumulated mud that will retain moisture and
tend to encourage rust. Oddly enough, the
best time to clean the underframe and wheel
arches is in wet weather when the mud is
thoroughly wet and soft. In very wet weather
the underframe is usually cleaned of large
accumulations automatically and this is a
good time for inspection.
Periodically, except on vehicles with a

6Bonnet - removal and refitting
2
Removal
1Open the bonnet, and support it in the fully
open position.
2On models fitted with an underbonnet lamp,
disconnect the battery negative lead, then
prise the lamp from the bonnet and disconnect
the wiring. If the bonnet is to be refitted, to aid
routing of the wiring on refitting, tie a length of
string to the end of the wiring. Then withdraw
the wiring through the bonnet and untie the
string, leaving it in position in the bonnet.
3Similarly, disconnect the windscreen
washer fluid hose from the connector in the
bonnet, but tie the string to the connector, to
prevent it from slipping into an inaccessible
position in the bonnet.
4Mark the position of the hinges on the
bonnet.
5With the help of an assistant, support the
weight of the bonnet, then unscrew the
securing bolts from the hinges, and lift the
bonnet from the vehicle (see illustration). If the
bonnet is to be refitted, rest it carefully on rags
or cardboard, to avoid damaging the paint.
6If a new bonnet is to be fitted, transfer all
the serviceable fittings (rubber buffers, lock
striker, etc.), to it.
7If desired, the bonnet hinges can be
removed from the vehicle, after unscrewing
the three bolts in each case securing them to
the upper flanges of the front wings.
Refitting
8Refitting is a reversal of removal,
remembering the following points.
9Align the hinges with the previously made
marks on the bonnet.10If the original bonnet is being refitted,
draw the windscreen washer fluid hose, and
where applicable, the underbonnet lamp
wiring, through the bonnet using the string.
11If the lock striker has been disturbed,
adjust it to the dimension shown (see
illustration), then tighten the locknut.
12If necessary, adjust the hinge bolts and
the front rubber buffers until a good fit is
obtained with the bonnet shut.

3To remove the bonnet lock striker from the
bonnet, loosen the locknut, then unscrew the
striker and recover the washers and spring.
When refitting, adjust the striker dimension as
described in Section 6, paragraph 11, before
tightening the locknut.
4To remove the locking spring, disconnect
the end of the bonnet release cable from the
spring. Then unhook the end of the spring
from the slot in the front body panel, and
manipulate the spring out through the top of
the panel, taking care not to damage the paint.

6Rear brake shoes (drum
brakes) - inspection, removal
and refitting
3
Note: When working on the brake
components, take care not to disperse brake
dust into the air, or to inhale it, since it may
contain asbestos, which can damage your
health.
Inspection
1It is recommended that the brake shoes are
inspected when necessary by removing the
drums. This will enable a proper inspection of
the linings to be made, and additionally, the
wheel cylinders can be inspected for leaks. If
preferred, however, a provisional inspection of
the state of wear of the rear shoe linings can
be made by removing the plugs from the
inspection holes in the brake backplates.2Use a torch or inspection lamp, and if
necessary a mirror, to check that the friction
material has not worn down to less than the
specified minimum.
3If any one of the shoes has worn below the
specified limit, all four rear brake shoes must
be renewed as a set, as follows.
Removal
4Where applicable, remove the wheel trims,
then loosen the rear roadwheel bolts and
chock the front wheels. Jack up the rear of the
vehicle, and support on axle stands (see
“Jacking and Vehicle Support”) positioned
under the body side members. Remove the
roadwheels.
5Fully release the handbrake.
6Extract the drum securing screw and
remove the drum. If the drum is tight, remove
the plug from the inspection hole in the brake
backplate, and push the handbrake operating
lever towards the brake shoe to move the
shoes away from the drum. If necessary,
slacken the handbrake cable adjuster (see
illustrations).
7Note the location and orientation of all
components before dismantling, as an aid to
reassembly.
8Clean the dust and dirt from the drum and
shoes, but take care not to inhale it.
9Remove the shoe hold-down pins, springs
and cups by depressing the cups and turning
them through 90°using a pair of pliers (see
illustrations). Note that the hold-down pins
are removed through the rear of the brake
backplate.
10Disconnect the handbrake cable from the
operating lever.11The upper and lower return springs may
now be unhooked and the shoes removed
separately, or the assembly of shoes, adjuster
strut and springs may be removed together.
Remove the hub, refer to Chapter 10, if
necessary. Take care not to damage the
wheel cylinder rubber boots. Before removing
the return springs, note the position and
orientation of the springs and adjuster strut.
12If the shoes are to be removed for some
time, fit a stout rubber band or a spring clip to
the wheel cylinder, to prevent the pistons from
being pushed out of their bores. In any event,
do not press the brake pedal while the drum is
removed.
Refitting
13Clean the dust and dirt from the brake
backplate, but take care not to inhale it.
14Apply a small amount of brake grease to
the shoe rubbing areas on the backplate.
15Investigate and rectify any source of
contamination of the linings (wheel cylinder or
hub bearing oil seal leaking).
16Although linings are available separately
(without shoes), renewal of the shoes
complete with linings is to be preferred,
unless the reader has the necessary skills and
equipment to fit new linings to the old shoes.
17If not already done, dismantle the shoes,
strut and springs. Note the position and
orientation of the components. On later
models (1992-on), the brake shoe lower
anchorage has been modified so that it is now
rectangular, necessitating modified brake
shoes and a modified lower return spring (see
illustration).
