spare tire FORD FIESTA 1989 Service Repair Manual

the corrosion which would otherwise occur
as the corrosion inhibitors become progress-
ively less effective. Always use an ethylene
glycol-based antifreeze which is suitable for
use in mixed-metal cooling systems.
20If the antifreeze used is to Ford’s
specification, the levels of protection it affords
are indicated in the Specifications Section of
this Chapter. To give the recommended
standard mixture ratio for this antifreeze, 40%
(by volume) of antifreeze must be mixed with
60% of clean, soft water; if you are using any
other type of antifreeze, follow its
manufacturer’s instructions to achieve the
correct ratio. It is best to make up slightly
more than the system’s specified capacity, so
that a supply is available for subsequent
topping-up.
21 Before adding antifreeze, the cooling
system should be completely drained,
preferably flushed, and all hoses checked for
condition and security. As noted earlier, fresh
antifreeze will rapidly find any weaknesses in
the system.
22 After filling with antifreeze, a label should
be attached to the expansion tank, stating the
type and concentration of antifreeze used,
and the date installed. Any subsequent
topping-up should be made with the same
type and concentration of antifreeze. If
topping-up using antifreeze to Ford’s
specification, note that a 50/50 mixture is
permissible, purely for convenience.
23 Do not use engine antifreeze in the
windscreen/tailgate washer system, as it will
damage the vehicle’s paintwork. A
screenwash additive should be added to the
washer system in its maker’s recommended
quantities.
Antifreeze - notes on renewal
24 Ford state that, where antifreeze to Ford
specification ESD-M97B-49-A is used, it will
last the lifetime of the vehicle. This is subject
to it being used in the recommended
concentration, unmixed with any other type of
antifreeze or additive, and topped-up when
necessary using only that antifreeze mixed 50/50 with clean water. If any other type of
antifreeze is added, the lifetime guarantee no
longer applies; to restore the lifetime
protection, the system must be drained and
thoroughly reverse-flushed before fresh
coolant mixture is poured in.
25
If the vehicle’s history (and therefore the
quality of the antifreeze in it) is unknown,
owners who wish to follow Ford’s
recommendations are advised to drain and
thoroughly reverse-flush the system before
refilling with fresh coolant mixture. If the
appropriate quality of antifreeze is used, the
coolant can then be left for the life of the
vehicle.
26 If any antifreeze other than Ford’s is to be
used, the coolant must be renewed at regular
intervals to provide an equivalent degree of
protection; the conventional recommendation
is to renew the coolant every two or three
years.
27 The above assumes the use of a mixture
(in exactly the specified concentration) of
clean, soft water and of antifreeze to Ford’s
specification or equivalent. It is also assumed
that the cooling system is maintained in a
scrupulously-clean condition, by ensuring that
only clean coolant is added on topping-up,
and by thorough reverse-flushing whenever
the coolant is drained.
General cooling system checks
28 The engine should be cold for the cooling
system checks, so perform the following
procedure before driving the vehicle, or
after it has been shut off for at least three
hours.
29 Remove the expansion tank filler cap, and
clean it thoroughly inside and out with a rag.
Also clean the filler neck on the expansion
tank. The presence of rust or corrosion in the
filler neck indicates that the coolant should be
changed. The coolant inside the expansion
tank should be relatively clean and
transparent. If it is rust-coloured, drain and
flush the system, and refill with a fresh coolant
mixture.
30 Carefully check the radiator hoses and heater hoses along their entire length; renew
any hose which is cracked, swollen or
deteriorated (see Section 5).
31
Inspect all other cooling system
components (joint faces, etc.) for leaks. A leak
in the cooling system will usually show up as
white- or rust-coloured deposits on the area
adjoining the leak. Where any problems of this
nature are found on system components,
renew the component or gasket with
reference to Chapter 3.
32 Clean the front of the radiator with a soft
brush to remove all insects, leaves, etc,
embedded in the radiator fins. Be careful not
to damage the radiator fins, or cut your fingers
on them.

39With the drivebelt tensioned correctly,
tighten the pivot and adjuster bolts to the
specified torque. Re-check the tension of the
drivebelt after tightening the bolts.
40 Reconnect the rigid brake pipes to the
modulator, tightening the unions to seal the
system.
41 Refit the modulator drivebelt cover and
secure with its two retaining bolts. Take care
not to damage the driveshaft CV joint gaiter as
the cover is eased into position.
42 Refit the belt-break switch to the
modulator drivebelt cover, taking care not to
damage the belt contact arm as it passes
through the cover.
43 Reconnect the modulator return hose by
pushing the hose firmly into its brake fluid
reservoir location, then lever out the collar to
retain it.
44 Refit the front suspension crossmember
and the one-piece undertray, as applicable.
45 Refit the roadwheels, then remove the
axle stands and lower the vehicle to the
ground. Tighten the wheel nuts to the
specified torque.
46 Top-up the brake fluid reservoir using
fresh fluid of the specified type (see “ Weekly
checks ”), then bleed the brake hydraulic
system in accordance with Section 14. Refit
the reservoir filler cap and the warning
indicator wiring multi-plug on completion.
47 Reconnect the battery negative lead.
Modulator drivebelt
48Disconnect the battery negative (earth)
lead (refer to Chapter 5A, Section 1).
49 Chock the rear wheels then jack up the
front of the car and support it on axle stands
(see “Jacking and Vehicle Support” ). Remove
the relevant front roadwheel.
50 Remove the one-piece undertray where
fitted, by turning its bayonet-type fasteners,
and on XR2i models, remove the front
suspension crossmember (see Chapter 10).
51 Remove the belt-break switch from the
relevant drivebelt cover, then remove the
drivebelt cover, as described in the previous
sub-Section.
52 Slacken the modulator pivot and adjuster
bolts to release drivebelt tension, then slip the
drivebelt from the modulator.
53 Remove the track rod end balljoint from
the steering arm on the spindle carrier (see
Chapter 10).
54 Disconnect the anti-roll bar connecting
link (where applicable) and release the brake
hose from their locations on the suspension
strut.
55 Remove the pinch bolt and nut securing
the lower suspension arm balljoint to the
spindle carrier, and separate the balljoint from
the spindle carrier assembly.
56 To release the driveshaft inner CV joint
from the differential, have an assistant pull the
spindle carrier away from the centre of the
vehicle whilst you insert a lever between the
inner CV joint and the transmission casing,
then firmly strike the lever with the flat of the hand, but be careful not to damage adjacent
components. Make provision for escaping
transmission oil, if possible plugging the
opening to prevent excessive loss. Do not
allow the CV joints to bend more than 20°
from the horizontal or internal damage may
occur. If both driveshafts are to be removed,
immobilise the differential by inserting an old
joint or suitable shaft, before the other
driveshaft is removed.
57
Slide the drivebelt off the driveshaft.
58 Remove the snap-ring from the groove in
the splines of the inner CV joint. This snap-
ring must be renewed every time the
driveshaft is withdrawn from the differential.
59 With the drivebelt removed, closely
examine the condition of the belt over its
entire length. Renew the belt if any cracks are
noticed in the fabric at the roots of the teeth, if
there is any abrasion of the fabric facing
material, or if there are any tears starting from
the edge of the belt.
60 If, since the drivebelts were last renewed,
a vehicle has covered more than 30 000 miles
(48 000 km) or a period of more than two
years has elapsed, the drivebelts should be
renewed as a matter of course.
61 Prior to refitting the drivebelt, thoroughly
clean its CV joint pulley location.
62 Fit the drivebelt over the driveshaft then,
with a new snap-ring fitted to the inner CV
joint splines, lubricate the splines with
transmission oil. Remove the temporary plug
and insert the inner CV joint to its
transmission casing location. Press against
the spindle carrier so that the snap-ring
engages fully to hold the CV joint splines in
the differential.
63 Refitting is now a reversal of the removal
procedure, tensioning the drivebelt as
described in the previous sub-Section. Ensure
that the pinch-bolt securing the lower
suspension arm balljoint to the spindle carrier
locates in the annular groove on the balljoint
spindle. Secure the track rod and balljoint,
using a new split pin. Tighten the suspension
components to their specified torque (see
Chapter 10).
64 Check the level of the transmission oil,
and top-up as required (see Chapter 1).
Modulator belt-break switch
65 Modulator belt-break switches are fitted
to each of the two drivebelt covers, and clip
into position. To remove, gently squeeze the
protruding lever on the switch towards the
main switch body and lift out, ensuring that
the belt contact arm does not catch on the
drivebelt cover.
25 Load-apportioning valve (ABS models) - adjustment
3
1Before attempting to adjust the load-
apportioning valves, the vehicle must be at its
kerb weight, ie with approximately half a tank
of fuel and carrying no load. Note that a
special setting tool will be required to adjust
the valves - this can be fabricated, to the
dimensions shown (see illustration).
2 Raise the vehicle on ramps or drive it over
an inspection pit, so that working clearance is
obtained with the full weight of the vehicle
resting on its roadwheels. Remove the spare
wheel and its carrier.
3 To check adjustment, insert the load-
apportioning valve setting tool into the nylon
sleeve without pre-loading the valve. If unable
to insert the tool, carry out the following
adjustment procedure.
4 Slacken the operating link adjustment fixing
screw then insert the setting tool into the
nylon sleeve, applying light pressure to the
operating link upper arm, so that the setting
tool fully locates. With the setting tool just
resting up against the adjustment post,
tighten the operating link adjustment fixing
screw to the specified torque (see
illustration) .
5 Repeat the procedure on the other valve.
6 Refit the spare wheel on completion.
