10Engine dismantling and
reassembly - general
4
General
1Ideally, the engine should be mounted on a
dismantling stand, but if this is not available,
stand the engine on a strong bench, at a
comfortable working height. Failing this, the
engine will have to be stripped down on the
floor.
2Cleanliness is most important, and if theengine is dirty, it should be cleaned with
paraffin in an upright position.
3Avoid working with the engine directly on a
concrete floor, as grit presents a real source
of trouble.
4If the engine oil appears extremely dirty or
contaminated, avoid inverting the engine until
the sump has been removed. This will prevent
any contaminated “sludge” from entering the
oilways.
5As parts are removed, clean them in a
paraffin bath. Do not immerse parts with
internal oilways in paraffin, as it is difficult to
remove, usually requiring a high pressure
hose. Clean oilways with nylon pipe cleaners.
6It is advisable to have containers available
to hold small items, to prevent loss and
confusion when refitting.
7Always obtain complete sets of gaskets
when the engine is being dismantled. Keep
the old gaskets as they can be used as
patterns to make replacements should new
gaskets not be available.
8Where possible, refit nuts, bolts and
washers to their locations after removal of the
relevant components, as this helps protect
the threads, and will also prove helpful during
reassembly.
9Retain unserviceable components, to
compare them with the new components
supplied.
10Many of the engine components are
secured using socket-headed “Torx” or
“Allen” bolts, and tools will be required to
remove and refit such bolts.
11Read through each relevant Section of
this Chapter carefullybeforebeginning work,
to ensure that any special tools that may be
required are available. Many components
(gaskets, oil seals, and certain bolts) must be
renewed on reassembly; where applicable,
obtain the required new components before
starting work.
12Before beginning a complete strip of the
engine, the following ancillary components
can be removed once the engine has been
removed from the vehicle:

If a tap is not available, cut
two slots into the threads of
one of the old flywheel bolts
and use the bolt to remove
the locking compound from the threads.

a)Inlet and exhaust manifolds (where
applicable)
b)Starter motor
c)Rear coolant gallery and hoses
d)Oil pressure switch
e)Oil temperature switch (where applicable)
f)Oil level sensor (where applicable)
g)Knock sensor (where applicable)
h)TDC sensor (where applicable)
i)Distributor components
j)Fuel pump (where applicable)
k)Thermostat/housing (N 16 NZ2, 1.8 and
2.0 litre models)
l)Power steering pump and mounting
bracket (where applicable)
m)Alternator mounting bracket
n)Engine lifting brackets
o)Dipstick/crankcase breather tube
p)Inlet manifold mounting bracket (where
applicable)
13To ensure maximum life, with minimum
trouble, from a rebuilt engine, not only must
everything be correctly assembled, but it must
also be spotlessly clean. All oilways and
coolant passages must be clear, and all
washers must be fitted in their original
positions. Oil all bearings and other moving
surfaces thoroughly with clean engine oil
during assembly.
14Before assembly begins, renew any bolts
or studs with damaged threads.
15Obtain a torque wrench, an angle-torque
gauge, sockets and bits, an oil can, clean
lint-free rag, and a set of engine gaskets and
oil seals, together with a new oil filter.16If they have been removed, new cylinder
head bolts, flywheel bolts, big-end bearing
cap bolts and main bearing cap bolts will also
be required.
17On completion of reassembly, refit the
applicable ancillary components listed in
paragraph 12.
18Follow procedure shown in Section 37.
11Timing belt and sprockets
(without automatic tensioner) -
removal, refitting and adjustment
3
Note: A two-legged puller may be required to
remove the crankshaft sprocket on N 16 NZ2,
1.8 and 2.0 litre models.Some of the later 1.4
and 1.6 litre engines, identifiable by the
squared-off top surfaces of the timing belt
covers, are fitted with spring-loaded auto-matic timing belt tensioners to ensure correct
belt tensioning on assembly.
Removal
1Disconnect the battery negative lead.
2On models with power steering, remove the
pump drivebelt, see Chapters 1 and 10.
3Remove the alternator drivebelt, as
described in Chapter 5.
4On C 16 NZ2, 1.8 and 2.0 litre models,
disconnect the wiring from the temperature
gauge sender.
5Release the securing clips (or hexagon-
headed screws, if fitted), and remove the main
outer timing belt cover, then unclip the smaller
outer timing belt cover from the coolant pump.
Where applicable, three screws retain the lower
(small) outer cover to the rear cover, the fourth
secures the tensioner (see illustrations).
6On 1.6 litre models with power steering,
remove the power steering pump, as
described in Chapter 10.
7Turn the crankshaft using a socket or
spanner on the crankshaft sprocket bolt, until
the timing mark on the camshaft sprocket is
aligned with the notch in the rear timing belt
cover, and the notch in the crankshaft pulley
is aligned with the pointer on the rear timing
belt cover (see illustrations). Note that on 1.4
litre engine there are two notches in the
crankshaft pulley, representing 5°and 10°
BTDC, and the 10°BTDC notch should be
aligned with the pointer (see illustration).
8Loosen the three coolant pump securing
bolts (see illustration), and turn the pump to
relieve the tension in the timing belt, then slide
the belt from the camshaft sprocket.

9The crankshaft pulley must now be
removed. On 1.4 and 1.6 litre engines (except
C 16 NZ2), the pulley is secured by a single
bolt, which also secures the crankshaft
sprocket. On C 16 NZ2, 1.8 and 2.0 litre
engines, the pulley is secured by four bolts,
which must be unscrewed using an Allen key
or hexagon bit. On manual transmission
models, if the engine is in the vehicle, the
crankshaft can be prevented from turning by
having an assistant engage first gear and
depress the brake pedal. Alternatively, the
flywheel ring gear teeth can be jammed using
a large screwdriver or similar tool.
10With the crankshaft pulley removed, the
timing belt can be withdrawn.
11If desired, the sprockets and the rear
timing belt cover can be removed as follows,
otherwise go on to paragraph 23.
12To remove the camshaft sprocket, firstdisconnect the breather hose(s) from the
camshaft cover, then unscrew the securing
bolts noting the locations of the HT lead
brackets and any other wiring brackets, and
remove the camshaft cover.
13Recover the gasket. Prevent the camshaft
from turning by holding it with a spanner on
the flats provided between No’s 3 and 4
camshaft lobes, and unscrew the camshaft
sprocket bolt.
14Withdraw the sprocket from the end of the
camshaft.
15To remove the crankshaft sprocket on 1.4
and 1.6 litre engines (except C 16 NZ2), if
necessary, remove the lower securing bolts
from the main rear timing belt cover and use
two large screwdrivers behind the cover to
lever off the sprocket. Remove the Woodruff
key if it is loose.
16To remove the crankshaft sprocket on C
16 NZ2, 1.8 and 2.0 litre engines, it will benecessary to prevent the crankshaft from
turning, as described in paragraph 9. Take
care when unscrewing the sprocket bolt, as it
is very tight. If necessary, use a two-legged
puller to remove the sprocket. Recover the
Woodruff key and the thrustwasher from the
end of the crankshaft.
17To remove the main rear timing belt cover
on C 16 NZ2, 1.8 and 2.0 litre models
disconnect the TDC sensor wiring plug and
unclip the wiring from the belt cover. Then
unscrew the two upper securing bolts and the
lower securing bolt(s) (one in the case of C 16
NZ2, 1.8 and 2.0 litre engines, two on other
SOHC engines). Withdraw the cover,
manipulating it from the smaller rear belt
cover on the coolant pump (see illustrations).
18If desired, the smaller rear belt cover can
be removed from the coolant pump, after
unscrewing the securing bolt (see
illustration), by rotating it to disengage it from
the retaining flange on the pump.
Refitting
19Refit the rear timing belt cover(s) using a
reversal of the removal procedure, and
ensuring that the main cover engages correctly
with the smaller cover on the coolant pump.
20On C 16 NZ2, 1.8 and 2.0 litre engines,
refit the thrustwasher and the Woodruff key to
the end of the crankshaft. Then refit the
crankshaft sprocket, and tighten the securing
bolt to the specified torque in the two stages
given in the Specifications. Ensure that the

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.
