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.

electric cooling fan assembly must be removed
to gain the clearance to remove the radiator.
2Disconnect the top and bottom hoses from
the radiator by slackening the hose clips and
pulling off the hoses with a twisting motion
(see illustrations). Do not use excessive force
- the radiator side tanks are made of plastic.
3On OHCmodels, disconnect the small hose
running from the expansion tank to the radiator.
4On automatic transmission models, clean
around the transmission fluid cooler unions on
the radiator and disconnect them (seeillustration). Be prepared for fluid spillage;
plug or cap the cooler lines to keep dirt out.
5On models with air conditioning, disconnect
the auxiliary fan thermo-switch. If the thermo-
switch is mounted in the radiator, remove It.
6Remove the upper half of the fan shroud by
removing the two bolts and two clips (see
illustration), and the lower half which is
secured by two bolts.
7Release the two radiator top mounting clips
by pulling out the plastic plugs (see illustration).
8Raise and support the front of the vehicle.
Support the radiator and remove the two
bottom mounting bolts (see illustration).
9Carefully lower the radiator slightly to free

the vehicle.
10If a new radiator is being fitted, transfer the
fan shrouds and mountings from the old one.
11Refit by reversing the removal operations,
then refill the cooling system.
12On automatic transmission models, check
the transmission fluid level.
1If the radiator has been removed because of
suspected blockage, reverse-flush it.
2Clean dirt and debris from the radiator fins,
using an air jet, or water and a soft brush. Be
careful not to damage the fins, or cut your
fingers. 3A radiator specialist can perform a “flow
test” on the radiator to establish whether an
internal blockage exists.
4A leaking radiator must be referred to a
specialist for permanent repair. Do not attempt
to weld or solder a leaking radiator, as
damage to the plastic parts may result.
5In an emergency, minor leaks from the
radiator can be cured by using a radiator
sealant while the radiator is in situ.
SOHC engines
1Disconnect the battery negative lead.
2Drain the cooling system. As it is not
necessary to completely drain the radiator, the
bottom hose can be disconnected from the
water pump.
3Disconnect the top hose from the
thermostat housing at the front of the cylinder
head (see illustration).
4Unscrew the bolts and remove the housing
and gasket (see illustration).
5Using a screwdriver, prise the retaining clip
from the housing, and extract the thermostat
and sealing ring (see illustrations).
6Clean the thermostat housing and cylinder
head mating surfaces. Obtain a new gasket for
reassembly, and if necessary a new sealing
ring too.
7Refit by reversing the removal operations.

17The thermostat is removed in the course
of water pump removal.
1A rough test of the thermostat may be made
by suspending it with a piece of string in a
saucepan full of water(see illustration).Bring
the water to the boil. The thermostat most
open by the time the water boils. If not, renew
it.
2If a thermometer is available, the precise
opening temperature of the thermostat may be
determined and compared with that given in
the Specifications.
3A thermostat which fails to close as the
water cools must also be renewed.
1Disconnect the battery negative lead.
2Remove the upper half of the fan shroud
(two bolts, four clips).
3Undo the nut which secures the fan clutch
to the water pump.This nut has a left-hand
thread, ie it is undone in a clockwise direction.
A thin cranked spanner, 32 mm (OHC) or 36
mm (V6) AF is needed(see illustration);
alternatively, if two of the pulley bolts are
removed, a normal thickness or even anadjustable spanner can be used (see
illustrations). Tap the spanner with a mallet if
need be to release the nut.
4The fan can now be unbolted from the
viscous clutch if required. Do not overtighten
the bolts when refitting.
5Refit by reversing the removal operations.
1Disconnect the battery negative lead.
2To provide additional clearance when
removing the cooling fan shroud assembly
(which is removed from below the vehicle),
apply the handbrake, then jack up the front of
the vehicle and support it securely on axle
stands (see “Jacking”).
3Disconnect the wiring plug(s) from the
motor(s), and where applicable, unclip the
wiring from the fan shroud.
4Unclip the expansion tank hose from the fan
shroud.
5Unscrew the two nuts securing the fan shroud
to the top of the radiator, then tilt the top of theshroud away from the radiator, and lift the
shroud to release the lower securing clips.
Withdraw the assembly from below the vehicle.
6To remove the fan blades, prise the
securing clip from the end of the motor shaft.
7The motor can be separated from the fan
shroud by unscrewing the three securing nuts
and bolts.
8Note that two cooling fans may be fitted,
depending on model. Both fans are secured to
the shroud in the same manner.
9Refitting is a reversal of removal, but when
fitting the fan blades, ensure that the drive dog
on the motor shaft engages with the slot in the
rear of the fan blades.
SOHC engines
1Disconnect the battery negative lead.
2Drain the cooling system.
3Remove the fan and viscous coupling.
4If not already done, remove the pump
drivebelt(s), then unbolt and remove the water
pump pulley (see illustration).
5Disconnect the radiator bottom hose and
the heater return hose from the pump.
6Remove the timing belt cover, which is
secured by three bolts.
