6Fit the new filter, ensuring that the arrows on
the filter body point in the direction of fuel flow.
7Tighten the clamp screw, and reconnect
the fuel inlet and outlet unions. Ensure that the
unions are correctly connected.
8Reconnect the battery negative lead, and
check the fuel line unions for leaks,
pressurising the system by switching the
ignition on and off several times.
All models except 2.0 litre SOHC
9Proceed as described for the 2.0 litre SOHCmodels, noting the following points.
10The fuel filter is located under the rear of
the vehicle, above the driveshaft (see
illustration). For access to the filter, chock
the front wheels, then jack up the rear of the
vehicle and support it on axle stands.
11To remove the filter, the mounting bracket
must first be removed from the floor, after
unscrewing the securing bolt. The filter can
then be removed from the bracket after
unscrewing the clamp bolt.On carburettor model SOHC engines,
renew the crankcase ventilation vent valve by
pulling it from the oil separator and loosening
the hose clip (see illustration). Fit the new
valve, tighten the clip, and insert it into the oil
separator grommet.
42Crankcase ventilation vent
valve renewal
If in doubt as to the condition of any of the
brake system seals and hoses, then renew
defective items whilst referring to the relevant
Sections of Chapter 10.
1An assistant and bleeding equipment will
be needed. A considerable quantity of
hydraulic fluid will be required - probably
about 2 litres (nearly half a gallon).
2Slacken the front wheel nuts. Raise and
support the front of the vehicle and remove
the front wheels.
3Remove the hydraulic fluid reservoir cap.
4Open both front bleed screws one full turn.
Attach one bleed tube to each screw, placing
the free end of each tube in a jar.
5Pump the brake pedal to expel fluid from
the bleed screws. Pause after each upstroke
to allow the master cylinder to refill.
6When air emerges from both bleed screws,
stop pumping. Detach the left-hand caliper
without disconnecting it and remove the
inboard brake pad.
7Depress the caliper piston, using a
purpose-made tool or a blunt item such as a
tyre lever, to force more fluid out of the
caliper. Hold the piston depressed and have
the assistant pump the pedal until air emerges
from the bleed screw again.8Tighten the bleed screw on the left-hand
caliper. Loosely refit the caliper and pad so
that the piston is not accidentally ejected.
9Repeat the purging operation on the right-
hand caliper, but do not refit it or tighten the
bleed screw yet.
10Fill the reservoir with fresh hydraulic fluid.
Position the bleed jar for the right-hand
caliper at least 300 mm (1 foot) above the
level of the bleed screw.
11Have the assistant pump the brake pedal
until fluid free of bubbles emerges from the
bleed screw. Tighten the bleed screw at the
end of a downstroke.
12Place a piece of wood in the caliper jaws
to limit piston travel. Keep your fingers clear
of the piston. Have the assistant depress the
brake pedal gentlyin order to move the
caliper piston out.
13With the pedal held depressed, slacken
the bleed screw on the right-hand caliper and
again depress the piston. Tighten the bleed
screw when the piston is retracted. The pedal
can now be released.
14Disconnect the bleed tube. Refit the right-
hand brake pad and caliper.
15Remove the left-hand caliper and inboard
pad again. Carry out the operations described
in paragraphs 10 to 14 on the left-hand
caliper.
16Bleed the rear brakes (Chapter 10).
17Refit the front wheels, lower the vehicle
and tighten the wheel nuts.
18Pump the brake pedal to bring the pads
up to the discs, then make a final check of the
hydraulic fluid level. Top-up and refit the
reservoir cap.Camshaft drivebelt renewal is
recommended as a precautionary measure for
SOHC engines but is compulsory for CVH
engines. Refer to Chapter 2 for the
appropriate renewal procedure.
1Disconnect the battery negative lead.
2It is preferable to drain the cooling system
with the engine cold. If this is not possible,
take precautions against scalding when
removing the expansion tank cap. Place a
thick rag over the cap and slacken the cap a
little to release any pressure. When all
pressure has been released, carry on
unscrewing the cap and remove it.
3Early models have no radiator drain plug, so
the radiator must be drained by detaching the
bottom coolant hose from the outlet on the
right-hand side of the radiator. Later SOHC
models have a drain plug located in the base
of the left-hand radiator end tank, whilst all
CVH models have a drain plug in the
right-hand radiator end tank and DOHC
models have a plug to the bottom right-hand
side of the radiator.
