dowels. Note that the gasket can only fit in one
position (see illustration). Do not use jointing
compound.
23Lower the cylinder head onto the gasket,
making sure that the locating dowels engage.
24Oil the threads of the new main cylinder
head bolts, and insert them into their locations
in the cylinder head.
25Tighten the bolts in the order shown (see
illustration)and in the four stages given in the
Specifications.
26Insert the three smaller M8 cylinder head
bolts through the top of the timing case (see
illustration)and tighten them to the specified
torque. Note that new bolts must be used, and
that they should be of the latest type with
hexagonal heads.
27Lubricate the cam follower bores in the
cylinder head, and the cam followers
themselves, then insert the cam followers into
their original locations in the cylinder head.
28Lubricate the camshaft bearing surfaces in
the cylinder head and the bearing caps.
29Lubricate the surfaces of the camshafts,
then carefully lay the camshafts in their original
positions in the cylinder head. Position the
camshafts with the slots in their front ends
pointing away from each other.
30Fit the bearing caps L1, L3, L5, R1, R3,
and R5 (see illustration), then lay the
camshaft oil spray bars and the timing chain
guide plate in position over the studs (see
illustrations).31Carefully tighten the bearing cap securing
nuts by hand in the following stages to lower
the camshafts into position.
Tighten the nuts for bearing caps L1 and R1
by half-a-turn (180°)
Tighten the nuts for bearing caps L5 and R5
by half-a-turn (180°)
Tighten the nuts for bearing caps L3 and R3
by half-a-turn (180°)
Continue to tighten the nuts in the small
stages given until the bearing caps contact the
cylinder head.

34Fit a newchain tensioner plunger
assembly to the housing in the cylinder head
with the piston uppermost. Before fitting the
new plunger assembly, take note of the
position of the piston (see illustration). The
assembly is normally supplied with the piston
protruding slightly from the cylinder, or slightlybelow the top surface of the cylinder (A). If the
new assembly is supplied with the piston
partially unlatched (B), or fully unlatched with
the latching ring visible (C), it must not be used.
35Locate the chain tensioner arm in position,
then insert the pivot pin, and secure it with the
circlip. Take care not to drop the circlip into
the timing case.
36Release the cable-tie securing the timing
chain, and lay the chain over the exhaust
camshaft sprocket, aligning the marks made
previously on the chain and sprocket, so that
the timing chain is taught on the exhaust side
of the engine.
37Fit the sprocket to the exhaust camshaft,
with the camshaft in the TDC position (ie with
the exhaust camshaft sprocket timing mark in
line with the top edge of the cylinder head,
pointing to the exhaust side of the engine, see
paragraph 4). If necessary, use a pair of pliers
on one of the unmachined sections of the
camshaft to turn the camshaft to the TDC
position. Take care not to damage the
machined surfaces of the camshaft.
38With the sprocket fitted, fit the spacer to
the end of the camshaft, and tighten the
securing bolt finger-tight (see illustration).

camshaft sprocket, aligning the marks made
previously on the chain and the sprocket.
40Fit the sprocket to the inlet camshaft, with
the camshaft in the TDC position (ie with the
inlet camshaft sprocket timing mark in line
with the top edge of the cylinder head,
pointing to the inlet side of the engine see
paragraph 4). Again, turn the camshaft if
necessary to enable the sprocket to be fitted.
41With the sprocket fitted, fit the distributor
rotor shaft to the end of the camshaft, and
tighten the securing bolt finger-tight. Note that
it is acceptable for the timing chain to sag
slightly between the two pulleys.
42Fit a new upper timing chain guide to the
plate at the front of the cylinder head.
43Turn the crankshaft clockwise until the
inlet camshaft begins to turn.
44If the chain tensioner plunger piston
protrudes from the cylinder, unlatch the piston by
pressing the chain tensioner arm down by hand.
45If the plunger piston is below the top
surface of the cylinder, a tool must be
fabricated to unlatch the piston (see
illustration). It is suggested that 2.5 mm
diameter welding rod is used to manufacture
the tool. Use the tool to release the piston as
follows.
46Carefully lift the chain tensioner arm with a
screwdriver, and insert the tool between the
tensioner arm and the piston. Remove the
screwdriver, and release the piston by
pressing the tensioner arm down by hand.
Carefully withdraw the tool once the piston
has been released.
47Tighten the camshaft sprocket securing
bolts to the specified torque, holding the
sprockets stationary as during removal.
48Turn the crankshaft clockwise through two
complete revolutions, and check that the
timing marks on the camshaft sprockets are
still aligned with the top face of the cylinder
head as described in paragraph 4.
49Turn the crankshaft clockwise through
another complete revolution, and check that
the timing marks on the camshaft sprockets
are facing each other, directly in line with the
top face of the cylinder head.
50If the timing marks do not align as
described, the timing chain has been
incorrectly fitted (probably one chain link awayfrom the correct position on one of the
camshaft sprockets), and the chain should be
removed from the sprockets and fitted in the
correct position.
51Inspect the oil seal in the upper timing
chain cover. If the oil seal is in good condition,
the cover can be refitted as follows, but if the
seal is damaged, or has been leaking, a new
seal should be fitted to the cover. If necessary,
carefully prise the old oil seal from the cover
using a screwdriver, and drive in the new seal
using a suitable metal tube. Make sure that the
seal lip faces into the engine. Take care not to
damage the timing chain cover.
52Fit the upper timing chain cover using a
new rubber gasket. Great care must be taken
to avoid damage to the oil seal when passing
the seal over the end of the inlet camshaft.
Careful manipulation will be required (possibly
using a thin feeler blade) to avoid damage to
the oil seal sealing lip. Note that the oil seal
should be fitted dry.
53Refit the timing chain cover securing bolts
and studs in their original locations and tighten
them to the specified torque (see illustration).
54Remove the reinforcing sleeves from the
camshaft cover, and renew the rubber sealing
rings. Note that the four short reinforcing
sleeves fit at the front of the cover (see
illustration).
55Refit the camshaft cover using a new
gasket, and tighten the securing bolts and
studs to the specified torque.
Note: A valve spring compressor will be
required during this procedure. New valve
stem oil seals should be used on reassembly.
Dismantle the cylinder head as described in
paragraphs 2 to 4, Section 12, PartA of this
Chapterand reassemble the head as
described in paragraphs 4 to 6, Section 42,
Part A of this Chapter, noting the following
points:
a)Ignore the references to the special tool.
b)Double valve springs are used on all the
valves (see illustration).
c)Refer to the following Section if the
cylinder head is to be inspected and
renovated.Refer to Part A, Section 34 of this Chapter,
noting the following points.
a)Valve and valve seat cutting and
regrinding can be carried out using
conventional tools.
b)The cylinder head cannot be resurfaced,
and if the surface distortion exceeds the
specified limits, the cylinder head must be
renewed.
Note: Once the timing chain has been
removed from the camshaft sprockets, do not
turn the crankshaft until the timing chain has
been correctly refitted - this is to prevent
contact between the valves and pistons. A
new timing chain tensioner plunger assembly,
a new upper timing chain cover gasket, and a
new camshaft cover and reinforcing sleeve
sealing rings must be used on refitting.
1If the engine is in the vehicle, carry out the
following operations.
a)Disconnect the battery negative lead.
b)On carburettor models, remove the air
cleaner.
c)On fuel-injection models, remove the air

13Apply a sealing compound to the faces of
the cylinder block and sump at the points
indicated(see illustration).
14Apply suitable thread-locking compound
to the sump securing studs and bolts, then
locate the sump on the cylinder block and fit
the securing nuts and bolts, but do not fully
tighten them at this stage.
15Align the sump so that the end faces and
the cylinder block are flush. To do this, use a
straight-edge. If the sump cannot be
positioned so that the faces of the cylinder
block and sump are flush, measure the
difference in height using a feeler blade as
shown (see illustration).
16Tighten the sump securing nuts and bolts
to the specified torque, then repeat the
measurement made in paragraph 15. If the
end faces of the sump and cylinder block are
not flush, suitable shims must be fitted
(available from a Ford dealer) between the
sump and the gearbox/transmission to
eliminate the clearance when mating the
engine to the gearbox/transmission. Note that
shims should be fitted at both sides of the
sump, as required. Select suitable shims from
those listed in the following table.
Clearance measuredShims required
0 to 0.25 mmNo shims required
0.25 to 0.29 mm0.15 mm (silver)
0.30 to 0.44 mm0.30 mm (light blue)
0.45 to 0.59 mm0.45 mm (red)
0.60 to 0.75 mm0.60 mm (black)
17If the engine is in the vehicle, reverse the
procedure described in paragraphs 3 to 8,
noting the following points.
a)Ensure that the roadwheels and the
steering wheel are in the straight-aheadposition then align the marks made on
removal and reconnect the intermediate
shaft to the steering gear. Tighten the
clamp bolt to the specified torque.
b)Fill the engine with the correct grade and
quantity of oil.
c)Refit the engine adapter plate and the
flywheel/driveplate.
d)Refit the gearbox or automatic
transmission, as applicable, ensuring that
the required shims are fitted between the
sump and the gearbox/transmission.
e)Tighten all fixings to the specified torque
where applicable.
Note: A suitable puller will be required to
remove the crankshaft pulley. A new
crankshaft pulley bolt, a new lower timing
chain cover gasket and a new oil pump gasket
must be used on refitting.
1If the engine is in the car, carry out the
following operations.
a)Disconnect the battery negative lead.
b)To Improve access, remove the radiator. It
will be difficult to remove the crankshaft
pulley with the radiator in place.
c)On fuel-injection models, remove the air
inlet hose, plenum chamber and air
cleaner lid as an assembly.
2Proceed as described in paragraphs 3 to 10
of Section 15.3Unscrew the four securing bolts and
withdraw the oil pump from the cylinder block
(see illustration). Recover the gasket and
discard it.
4If desired, the pump can now be dismantled
and inspected.
5Thoroughly clean the mating faces of the
pump and the cylinder block.
6Prime the pump by injecting clean engine oil
into it and turning it by hand.
7Place a new gasket on the oil pump flange,
ensuring that the gasket is correctly located so
that the holes align with the oil passages in the
pump.
8Fit the oil pump, and tighten the securing
bolts to the specified torque.
9Proceed as described in paragraphs 28 to 40
of Section 15.
10If the engine is in the vehicle, reverse the
operations described in paragraph 1.
1The oil pump can be dismantled for
cleaning, but if any of the components are
worn, the pump must be renewed as an
assembly.

9Extract the bearing shells, and recover the
thrustwashers, keeping them identified for
location.
10The crankshaft and bearings can be
examined and if necessary renovated.
11Commence refitting as follows(see
illustration).
12Wipe the bearing shell locations in the
crankcase, and the crankshaft journals with a
soft non-fluffy rag.
13If the old main bearing shells are to be
renewed (not to do so is a false economy,
unless they are virtually new) fit the five upper
halves of the main bearing shells to their
locations in the crankcase.
14Fit the thrustwashers to the centre main
bearing location, using a little grease to retain
them if necessary. The oil grooves in the
thrustwashers must face outwards (ie facing
the crankshaft webs). Note that where
standard thrustwashers have been fitted in
production, the centre main bearing is
unmarked, but if oversize (0.38 mm)
thrustwashers have been fitted, the centre
main bearing will carry a yellow paint mark.
15Lubricate the crankshaft journals and the
upper and lower main bearing shells with
clean engine oil, then carefully lower the
crankshaft into the crankcase.
16Lubricate the crankshaft main bearing
journals again, and then fit the main bearing caps
in their correct locations, with the arrows on the
caps pointing towards the front of the engine.
17Fit the main bearing cap bolts, noting that
the studded bolts secure bearing caps Nos 3
and 5.
18Lightly tighten all the securing bolts, then
progressively tighten all bolts to the specified
torque.
19Check that the crankshaft rotates freely.
Some stiffness is to be expected with newcomponents, but there must be no tight spots
or binding.
20Check that the crankshaft endfloat is
within the specified limits by inserting a feeler
blade between the centre crankshaft web and
the thrustwashers.
21Refit the sump mounting plate to the front
of the cylinder block, and tighten the securing
bolts to the specified torque.
22Carefully wind a thin layer of tape around
the rear edge of the crankshaft to protect the
oil seal lips as the rear oil seal is installed.
23Refit the crankshaft rear oil seal housing,
using a new gasket, and tighten the securing
bolts to the specified torque.
24Install the new oil seal with reference to
Section 24.
25With the oil seal installed, carefully pull the
tape from the edge of the crankshaft.
26Refit the pistons and connecting rods as
described previously in this Chapter.
27Refit the flywheel/driveplate, and the
timing chain and crankshaft sprocket.
Proceed as described in Part A, Section 27
of this Chapter, noting that the production
bearing undersizes are indicated as follows.
Yellow or red paint marks on crankshaft —
standard diameter main bearing journals.
Green line on crankshaft front counterweight
— main bearing journals 0.25 mm
undersize.
Green spot on counterweight — big-end
bearing journals 0.25 mm undersize.
Refer to Part A, Section 25 of this Chapter,
but note that the connecting rod bolts should
be renewed on reassembly, and when
renewing the cylinder head bolts, the latest
type bolts with hexagonal heads should
always be used.
Proceed as described in Part A, Section 35
of this Chapter, noting the following points.
a)If the cylinder head has been removed,
pay particular attention to the note at the
beginning of Section 18.
b)If removed during any dismantling
operations, new flywheel driveplate bolts
and connecting rod bolts must be used.
c)After reassembling the main engine
components, refer to paragraph 3 of
Section 14 and refit the ancillary
components listed.Refer to Part A, Section 51 of this Chapter,
but note that when the engine is first started, a
metallic tapping noise may be heard. This is
due to the timing chain tensioner plunger
assembly taking time to pressurize with oil,
resulting in a temporarily slack chain. The
noise should stop after a short time, once oil
pressure has built up.
1When engine performance is down, or if
misfiring occurs which cannot be attributed to
the ignition or fuel system, a compression test
can provide diagnostic clues. If the test is
performed regularly it can give warning of
trouble before any other symptoms become
apparent.
2The engine must be at operating
temperature, the battery must be fully charged
and the spark plugs must be removed. The
services of an assistant will also be required.
3Disable the ignition system by dismantling
the coil LT feed. Fit the compression tester to
No 1 spark plug hole. (The type of tester which
screws into the spark plug hole is to be
preferred.)
4Have the assistant hold the throttle wide
open and crank the engine on the starter.
Record the highest reading obtained on the
compression tester.
5Repeat the test on the remaining cylinders,
recording the pressure developed in each.
6Desired pressures are given in the
Specifications. If the pressure in any cylinder
is low, introduce a teaspoonful of clean engine
oil into the spark plug hole and repeat the test.
7If the addition of oil temporarily improves
the compression pressure, this indicates that
bore or piston wear was responsible for the
pressure loss. No improvement suggests that
leaking or burnt valves, or a blown head
gasket, may be to blame.
8A low reading from two adjacent cylinders is
almost certainly due to the head gasket
between them having blown.
9On completion of the test, refit the spark
plugs and reconnect the coil LT feed.

3Recover the oil pump driveshaft, noting
which way round it is fitted.
4Recover the oil pump-to-block gasket.
2.4 & 2.9 litre engines
5Remove the sump.
6Unbolt the oil pump/inlet pipe assembly and
remove it then extract the driveshaft, which is
splined into the distributor shaft (see illustration).
1Remove the cylinder heads,the sump and
the oil pump.
2Check that the big-end bearing caps and
connecting rods have identification marks. This
is to ensure that the correct caps are fitted to the
correct connecting rods and at reassembly are
fitted in their correct cylinder bores. Note that
the pistons have an arrow (or notch) marked on
the crown to indicate the forward facing side.
3Remove the big-end nuts and place to one
side in the order in which they are removed.
4Pull off the big-end caps, taking care to
keep them in the right order and the correct
way round. Also ensure that the shell bearings
are kept with their respective connecting rods
unless they are being renewed.5To remove the shell bearings, press the
bearing on the side opposite the groove in
both the connecting rod and the cap, and the
bearing will slide out.
6Withdraw the pistons and connecting rods
upwards out of the cylinder bores.
1Remove the cylinder heads and pushrods.
2Remove the tappets from their bores, using
a pencil magnet or by inserting a piece of bent
brass wire through the lubrication holes (see
illustration).
3Remove the timing cover and the camshaft
gear.
4Remove the two bolts which secure the
camshaft thrust plate. Withdraw the camshaft,
thrust plate and spacer ring.
5The intermediate plate may now be
removed after removing the retaining bolts.
Note the oil seals on the timing cover locating
dowels, which must also be removed.
1The engine must be removed from the
vehicle for this task.
2Remove the flywheel/driveplate, timing
cover and crankshaft gear, and the pistons
and connecting rods, as described in the
preceding Sections. (If no work is to be done
on the pistons, they need not actually be
pushed out of their bores.)
3Make sure that the main bearing caps carry
identification marks, then remove the bolts
and lift off the caps. Tap the caps with a soft-
faced mallet if necessary to free them.
4Note that the rear main bearing cap also
retains the crankshaft rear oil seal, and that the
shells for No 3 main bearing have thrust
flanges to control crankshaft endfloat.
5Lift out the crankshaft. Do not drop it, it is
heavy.
6Recover the upper half main bearing shells
from their seats in the crankcase, again
keeping them in order if they are to be re-
used.
7Remove the old oil seal from the rear of the
crankshaft.
Refer to Part A, Section 23 of this Chapter.1Disconnect the battery negative lead.
2Remove the crankshaft pulley (and damper,
when fitted).
3Extract the old oil seal by levering it out with
a hooked tool.
4Clean out the seal seat in the timing cover.
Lubricate the new seal and fit it, lips inwards. Seat
the seal with a piece of tube or a large socket. (If
available, Ford tool 21-063 and a non-damper
type pulley may be used to seat the seal.)
5Lubricate the sealing surface of the pulley or
damper and refit it.
6The remainder of refitting is a reversal of the
removal procedure. Check the engine oil level
on completion.
Refer to Part A, Section 18 of this Chapter.
Refer to Part A, Section 25 of this Chapter.
New cylinder head bolts are not required if
they are of the hexagon head type. Torx type
bolts must be renewed. The two types of
cylinder head bolt must not be mixed on the
same engine.
1Tap out the roll pin from one end of the
rocker shaft and remove the spring washer
(see illustration).
2Slide the rocker arms, rocker supports and
springs off the rocker shaft. Keep them in the
correct order so that they can be reassembled
in the same position (see illustration).

3Examine the rocker shaft and rocker arms for
wear. If the rocker arm surface that contacts the
valve stem is considerably worn, renew the
rocker arm. If it is worn slightly step-shaped it
may be cleaned up with a fine oil stone.
4Oil the parts and reassemble them on their
shafts in the original order. With both rocker
shafts fitted the oil holes must face
downwards to the cylinder heads. This
position is indicated by a notch on one end
face of the rocker shaft (see illustration).
Inspect the tappets for scuffing, surface wear
or other damage. Renew them if necessary. It is
good practice to renew the tappets if a new
camshaft is being fitted.Check the pushrods for bending by rolling
them on a flat surface. Straighten or renew as
necessary. Also check the pushrod ends for
wear or damage.
1If there is excessive wear in the camshaft
bearings they will have to be renewed. As the
fitting of new bearings requires special tools
this should be left to your local Ford dealer.
2The camshaft may show signs of wear on
the bearing journals or cam lobes. The main
decision to take is what degree of wear
necessitates renewing the camshaft, which is
expensive. Scoring or damage to the bearing
journals cannot be removed by regrinding;
renewal of the camshaft is the only solution.
3The cam lobes may show signs of ridging or
pitting on the high points. If ridging is slight
then it may be possible to remove it with a fine
oil stone or emery cloth. The cam lobes,
however, are surface hardened and once the
hard skin is penetrated wear will be very rapid.
4Excessive endfloat of the camshaft may be
remedied by fitting a thicker spacer and/or
thrust plate - see Specifications.
5Excessive backlash in the camshaft drive
gears (timing gears), which will have been
noticed before dismantling by virtue of the
characteristic growling noise, can only be
remedied by renewing the gears.1Clean the dirt and oil off the cylinder heads.
Remove the carbon deposits from the
combustion chambers and valve heads with a
scraper or rotary wire brush.
2Remove the valves by compressing the
valve springs with a suitable valve spring
compressor and lifting out the collets. Release
the valve spring compressor and remove the
valve spring retainer, spring and valve (see
illustrations).Note: When removing and
refitting the valve spring take care not to
damage the valve stem when pressing down
the valve spring retainer to remove or refit the
collets. If the stem gets damaged the sealing
will be ineffective and result in excessive oil
consumption and wear of the valve guides.
3Remove the valve stem oil seals from the
valve guides and discard them.
4With the valves removed clean out the
carbon from the ports.
5Examine the heads of the valves and the
valve seats for pitting and burning. If the
pitting on valve and seat is slight it can be
removed by grinding the valves and seats
together with coarse, and then fine, valve
grinding paste.
6Severe pitting or burning of the valves
probably means that they must be renewed.
Badly burnt valve seats can be recut, or
inserts can be fitted, by a Ford dealer or other
specialist.
7Check the valve guides for wear by inserting
the valve into its guide until the valve stem is
flush with the end of the guide, then checking
the play at the valve head(see illustration).
Movement in excess of 0.6 mm (0.024 in)
means that the clearance between guide and
stem is excessive.
8Valve guide wear is dealt with by reaming
the guides to a known oversize and fitting new
valves with oversize stems. Again, this is a
dealer or specialist task.

2If the Woodruff keys were removed from the
camshaft and crankshaft, refit them.
3Refit the crankshaft gear, if removed, using
a length of tube to drive it home.
4Position the camshaft and crankshaft so
that their keyways are facing each other(seeillustration).Slide the camshaft gear onto the
camshaft, rotating the shafts slightly if
necessary so that the marks on the two gears
are aligned. Remember that there are two
marks on the crankshaft gear.
5Fit the camshaft gear retaining bolt and
washer(see illustration).Tighten the bolt to
the specified torque.
6Apply sealant to the mating faces of the
timing cover and the intermediate plate.
7Position a new gasket on the intermediate
plate and fit the timing cover to the cylinder
block (see illustrations).
8Fit the timing cover bolts, but do not tighten
them yet.
9Oil the sealing face of the crankshaft pulley
or damper. Fit the pulley/damper and the
central bolt and washer, applying sealant to
the inboard face of the washer (see
illustration). Draw the pulley/damper into

Cooling system
The cooling system is of pressurised type
and includes a front mounted crossflow
radiator, belt-driven water pump, temperature-
sensitive thermo-viscous fan (on DOHC
models, an electrically-operated cooling fan is
fitted, operated by a switch in the thermostat
housing), wax type thermostat, and an
expansion and degas tank.
The radiator matrix is of copper and brass
construction and the end tanks are of plastic.
On automatic transmission models the right-
hand side end tank incorporates the
transmission oil cooler.
The thermostat is located behind the water
outlet elbow at the front of the cylinder head
on OHCmodels, and on the front of the water
pump on V6 models. Its purpose is to ensure
rapid engine warm-up by restricting the flow of
coolant in the engine when cold, and also to
assist in regulating the normal operating
temperature of the engine.
The expansion tank incorporates a pressure
cap which effectively pressurises the cooling
system as the coolant temperature rises,
thereby increasing the boiling point of the
coolant. The tank also has a further degas
function. Any accumulation of air bubbles in
the coolant, in particular in the thermostat
housing and the radiator, is returned to the
tank and released in the air space thus
maintaining the efficiency of the coolant.
On models fitted with the auxiliary warning
system, the expansion tank contains a level
sensor which operates a warning light if the
coolant level falls significantly.
When the engine is started from cold, the
water pump circulates coolant around the
cylinder block, cylinder head(s) and inlet
manifold. The warm coolant passes through
the automatic choke housing (when
applicable) and through the heater matrix
before returning to the engine. As the coolant
expands, the level in the expansion tank rises.
Circulation of coolant through the radiator is
prevented while the thermostat is shut. When
the coolant reaches the predeterminedtemperature the thermostat opens and hot
water passes through the top hose to the top
of the radiator. As the water circulates down
through the radiator, it is cooled by the
passage of air past the radiator when the car is
in forward motion, supplemented by the action
of the thermo-viscous fan when necessary.
Having reached the bottom of the radiator, the
water is now cool and the cycle is repeated.
Circulation of water continues through the
expansion tank, inlet manifold and heater at all
times; the heater temperature control being by
an air flap.
The thermo-viscous fan is controlled by the
temperature of air behind the radiator. When
the air temperature reaches a predetermined
level, a bi-metallic coil commences to open a
valve within the unit and silicon fluid is fed
through a system of vanes. Half of the vanes
are driven directly by the water pump and the
remaining half are connected to the fan blades.
The vanes are arranged so that drive is
transmitted to the fan blades in relation to the
drag or viscosity of the fluid, and this in turn
depends on ambient temperature and engine
speed. The fan is therefore only operated when
required, and compared with direct drive type
fan represents a considerable improvement in
fuel economy, drivebelt wear and fan noise.
Air conditioning
Air conditioning is fitted as standard on
Scorpio models and is optionally available on
some other models. In conjunction with the
heater, the system enables any reasonable air
temperature to be achieved inside the car, it
also reduces the humidity of the incoming air,
aiding demisting even when cooling is not
required.
The refrigeration side of the air conditioning
system functions in a similar way to a
domestic refrigerator. A compressor, belt-
driven from the crankshaft pulley, draws
refrigerant in its gaseous phase from an
evaporator. The compressed refrigerant
passes through a condenser where it loses
heat and enters its liquid phase. After
dehydration the refrigerant returns to the
evaporator where it absorbs heat from air
passing over the evaporator fins. The
refrigerant becomes a gas again and the cycle
is repeated.Various subsidiary controls and sensors
protect the system against excessive
temperature and pressures. Additionally,
engine idle speed is increased when the
system is in use to compensate for the
additional load imposed by the compressor.
Precautions
Antifreeze mixture
Antifreeze mixture is poisonous. Keep it out
of reach of children and pets. Wash splashes
off skin and clothing with plenty of water.
Wash splashes off vehicle paintwork to avoid
discolouration.
Antifreeze/water mixture must be renewed
every two years to preserve its anti-corrosive
properties. In climates where antifreeze
protection is unnecessary, a corrosion
inhibitor may be used instead - consult a Ford
dealer. Never run the engine for long periods
with plain water as coolant. Only use the
specified antifreeze, as inferior brands may not
contain the necessary corrosion inhibitors, or
may break down at high temperatures.
Antifreeze containing methanol is particularly
to be avoided, as the methanol evaporates.
The specified mixture is 45 to 50%
antifreeze and 50 to 55% clean soft water (by
volume). Mix the required quantity in a clean
container.
Air conditioning refrigerant
Although the refrigerant is not itself toxic, in
the presence of a naked flame (or a lighted
cigarette) it forms a highly toxic gas. Liquid
refrigerant spilled on the skin will cause
frostbite. If refrigerant enters the eyes, rinse
them with a dilute solution of boric acid and
seek medical advice immediately.
In view of the above points, and of the need
for specialised equipment for evacuating and
recharging the system, any work which
requires the disconnection of a refrigerant line
must be left to a specialist.
Do not allow refrigerant lines to be exposed
to temperatures above 110°C (230°F) - eg
during welding or paint drying operations and
do not operate the air conditioning system if it
is known to be short of refrigerant, or further
damage may result.
