6Carefully withdraw the bumper from the
vehicle.

7Refitting is a reversal of removal.
Rear bumper
Removal
8Remove the rear trim panel from the
luggage compartment by prising up the top
edge to release the clips, then lift the panel
upwards to free it from the lower locating
tags. The bumper retaining nuts are now
exposed (see illustrations).
9Note that the bumper is removed as a
complete assembly with its lower trim panel.
10Disconnect the battery negative lead, then
prise the number plate lamp from the bumper,
and disconnect the wiring.
11Unscrew the bumper retaining nuts, and
recover the washers. On DOHC models, the
bumper securing nuts are accessible from
underneath the vehicle.
12Where fitted, remove the special locking
rivets, one each side, securing the bumper to
the wheel arch.
13Additional clips may be present on the
underside of the bumper which must also be
removed.
14Release the bumper retaining clips at the
front edges of the bumper by tapping the
centre pin through the expanding clip, using a
pin punch or similar. The pin will drop out as it
is pushed through - recover it for refitting.
15Push each end of the bumper towards the
rear of the vehicle, then pull the end of the
bumper from the rear wing.16Carefully withdraw the bumper from the
vehicle, taking care not to strain the number
plate lamp wiring.
Refitting
17Refitting is a reversal of removal. The
expanding clips at the front edges of the
bumper are secured by pushing the pin into
the clip until flush.
29Radiator grille panel -
removal and refitting
2
All SOHC models
Removal
1With the bonnet fully open and supported,
pull the upper edge of the grille panel
forwards and free the retaining clips using a
screwdriver. Then lift the panel to release the
lower locating lugs from their grommets in the
lower body front panel (see illustration).
Refitting
2Refitting is a reversal of removal, but ensure
that the lower locating lugs seat correctly in
their grommets, and take care not to push the
grommets from their holes in the body front
panel.
DOHC and 1993-on models
Removal
3Extract the three screws securing the grille
panel to the body front panel, then lift the
grille panel to release the lower locating lugs
from their grommets in the lower body front
panel.
Refitting
4Refitting is a reversal of removal, with
reference to paragraph 2.
30Windscreen cowl panel -
removal and refitting
2
Removal
1Remove the wiper arms, referring to
Chapter 12, if necessary.2Disconnect the washer fluid hose from the
reservoir, and feed it through the cowl panel,
noting its routing as a guide to refitting. Be
prepared for fluid spillage.
3Where applicable, disconnect the battery
negative lead, then disconnect the
underbonnet lamp wiring plug and feed it
through the cowl panel, noting its routing as a
guide to refitting.
4Working from one end of the cowl panel,
carefully prise the panel from the body. Care
must be taken, as the panel is easily
damaged.
Refitting
5Refitting is a reversal of removal, ensuring
that the panel is correctly seated along its
length, and that the washer fluid hose, and
where applicable the underbonnet lamp
wiring, is correctly routed.
31Wheel arch liners - general
2
1The plastic wheel arch liners are secured by
a combination of self-tapping screws and
plastic clips. Removal and refitting is self
explanatory, remembering the following
points (see illustration).
2Some of the securing clips may be held in
place using a central pin, which must be
tapped out to release the clip.
3The clips are easily broken during removal,
and it is advisable to obtain a few spare clips
for possible use when refitting.

MOTTest Checks REF•9
Seat belts and seats
Note: The following checks are applicable to
all seat belts, front and rear.
MExamine the webbing of all the belts
(including rear belts if fitted) for cuts, serious
fraying or deterioration. Fasten and unfasten
each belt to check the buckles. If applicable,
check the retracting mechanism. Check the
security of all seat belt mountings accessible
from inside the vehicle.
MThe front seats themselves must be
securely attached and the backrests must
lock in the upright position.
Doors
MBoth front doors must be able to be opened
and closed from outside and inside, and must
latch securely when closed.
Vehicle identification
MNumber plates must be in good condition,
secure and legible, with letters and numbers
correctly spaced – spacing at (A) should be
twice that at (B).
MThe VIN plate and/or homologation plate
must be legible.
Electrical equipment
MSwitch on the ignition and check the
operation of the horn.
MCheck the windscreen washers and wipers,
examining the wiper blades; renew damaged
or perished blades. Also check the operation
of the stop-lights.
MCheck the operation of the sidelights and
number plate lights. The lenses and reflectors
must be secure, clean and undamaged.
MCheck the operation and alignment of the
headlights. The headlight reflectors must not
be tarnished and the lenses must be
undamaged.
MSwitch on the ignition and check the
operation of the direction indicators (including
the instrument panel tell-tale) and the hazard
warning lights. Operation of the sidelights and
stop-lights must not affect the indicators - if it
does, the cause is usually a bad earth at the
rear light cluster.
MCheck the operation of the rear foglight(s),
including the warning light on the instrument
panel or in the switch.
Footbrake
MExamine the master cylinder, brake pipes
and servo unit for leaks, loose mountings,
corrosion or other damage.
MThe fluid reservoir must be secure and the
fluid level must be between the upper (A) and
lower (B) markings.MInspect both front brake flexible hoses for
cracks or deterioration of the rubber. Turn the
steering from lock to lock, and ensure that the
hoses do not contact the wheel, tyre, or any
part of the steering or suspension mechanism.
With the brake pedal firmly depressed, check
the hoses for bulges or leaks under pressure.
Steering and suspension
MHave your assistant turn the steering wheel
from side to side slightly, up to the point where
the steering gear just begins to transmit this
movement to the roadwheels. Check for
excessive free play between the steering
wheel and the steering gear, indicating wear or
insecurity of the steering column joints, the
column-to-steering gear coupling, or the
steering gear itself.
MHave your assistant turn the steering wheel
more vigorously in each direction, so that the
roadwheels just begin to turn. As this is done,
examine all the steering joints, linkages,
fittings and attachments. Renew any
component that shows signs of wear or
damage. On vehicles with power steering,
check the security and condition of the
steering pump, drivebelt and hoses.
MCheck that the vehicle is standing level,
and at approximately the correct ride height.
Shock absorbers
MDepress each corner of the vehicle in turn,
then release it. The vehicle should rise and
then settle in its normal position. If the vehicle
continues to rise and fall, the shock absorber
is defective. A shock absorber which has
seized will also cause the vehicle to fail.

The vehicle owner who does his or her own maintenance according to
the recommended service schedules should not have to use this section
of the manual very often. Modern component reliability is such that,
provided those items subject to wear or deterioration are inspected or
renewed at the specified intervals, sudden failure is comparatively rare.
Faults do not usually just happen as a result of sudden failure, but
develop over a period of time. Major mechanical failures in particular are
usually preceded by characteristic symptoms over hundreds or even
thousands of miles. Those components that do occasionally fail without
warning are often small and easily carried in the vehicle.
With any fault-finding, the first step is to decide where to begininvestigations. Sometimes this is obvious, but on other occasions, a
little detective work will be necessary. The owner who makes half a
dozen haphazard adjustments or replacements may be successful in
curing a fault (or its symptoms). However, will be none the wiser if the
fault recurs, and ultimately may have spent more time and money than
was necessary. A calm and logical approach will be found to be more
satisfactory in the long run. Always take into account any warning
signs or abnormalities that may have been noticed in the period
preceding the fault - power loss, high or low gauge readings, unusual
smells, etc. - and remember that failure of components such as fuses
or spark plugs may only be pointers to some underlying fault.
