approximately two minutes.
The pressure
should not drop during this time.
If the system holds pressure, proceed to step

cooling system, repair any coolant leaks found
and
fill and bleed the cooling system as
necessary.

Coolant Expansion Tank Cap Pressure Test
A WARNING:When releasing the system
pressure, cover the expansion tank cap
with a thick cloth to prevent the possibility
of coolant scalding, Failure to follow this
instruction may result in personal injury.
1. Remove the coolant expansion tank cap.
2. Use water to clean the area of the rubber seal
and pressure relief valve. Install the pressure
tester and adapter and immerse the
coolant
expansion tank cap in water .
N0TE:lf the plunger of the pump is depressed too
quickly, an erroneous pressure reading will result. l-
3. Slowly depress the plunger of the pressure test
pump until the pressure gauge reading stops
increasing, and note the highest pressure
reading obtained.
4.
Release pressure by turning the pressure relief
screw counterclockwise. Tighten the pressure
relief screw and repeat step 3 at least twice to
make sure the pressure test reading is
repeatable and within acceptable gauge reading
limits of the coolant expansion tank cap.
5.
If the pressure test gauge readings are not
within the
acceptable gauge reading limits,
INSTALL a new coolant expansion tank cap.
6. Recheck the system by repeating steps 3 and
4 at least twice.

REFER to:
RoadlRoller Testing (1 00-00 General
Information, Description and Operation).
4. Drive the vehicle at a constant throttle opening
and set speed until the ECT value settles into
a shallow rise and fall signal, close to a straight
line. This indicates that the thermostat is
functioning correctly.
N0TE:Some thermostats indicate the
temperature(s) in Celsius and Fahrenheit.
The graphic below shows the location and an
example of the opening temperature

risequite quickly with smooth progression.
If
the ECT signal appears unstable or erratic, the
ECT sensor, electrical connector and wiring
harness to the PCM need to be visually inspected
for damage, chafing or water ingress.
The temperature should rise to approximately
90°C
for a thermostat that has an 88OC value. The signal
value will then fall as cooler coolant enters the
engine.
If the ECT value fails to maintain a constant value
and falls back to lower figures, typically between
60°C (140°F) and 70°C (1 50°F), the thermostat
and its sealing function within the thermostat
housing must be checked.
5. INSTALL a new thermostat.

303-03B-7 Engine Cooling - 2.OL Duratec-HE (M14) 303-03B-7
DESCRIPTION AND OPERATION
Oil Cooler
Item Description
I I I Oil cooler I
1 2 1 Oil filter adaptor I
1 3 1 Oil filter I
The oil cooler is an oil to water type and is a full
flow system.
The oil cooler and oil filter are fitted to an adaptor
which is mounted on the cylinder block.
The coolant supply for the oil cooler is through the
thermostat by-pass hose.
Coolant Recovery System
A pressurized coolant expansion tank system is
used which continuously separates the air from the
cooling system and replenishes the system through
the coolant expansion tank outlet hose.
A continuous vent from the engine and radiator to
I the coolant expansion tank prevents air locks from
forming in the cooling system.
No manual bleed points are provided on the
system. The coolant expansion tank serves
as the location
for:
Service fill.
Coolant expansion during warm-up.
Air separation during operation.
System pressurization by the coolant pressure
cap.
Coolant
A WARN1NG:Coolant contains monoethylene
glycol and other constituents which are
toxic if taken internally and can be
absorbed into the skin after prolonged
contact. Failure to follow this instruction
may result in personal injury.
Coolant concentration should be checked through
the neck of the expansion tank with a hydrometer.
The acceptable range of specific gravity (sg) of
correctly balanced fluids is between
1.06 and
1.07kg/l, which represents a coolant concentration
between 40% and 55%. If the concentration falls
below 40% there is insufficient low temperature
protection and the corrosion resistance will be
inadequate. In such cases the concentration must
be brought back to specification.
The coolant used is the orange-colored Motorcraft
Super Plus 2000. Motorcraft Super Plus 2000 is a
non silicated organic acid technology (OAT)
coolant, and must not be mixed with other coolant
types. For cooling system top up, only use coolant
which meets the correct specification and is
compatible with the existing coolant.
Changing Coolant
A WARN1NG:When releasing the cooling
system pressure, cover the coolant
expansion tank cap with a thick cloth to
prevent the possibility of coolant scalding.
Failure to follow this instruction may result
in personal injury.
A CAUTI0N:When draining the coolant or
changing any cooling system components,
it is imperative that no coolant comes into
contact with the camshaft drive belt or
accessory drive belt. If necessary the belt
should be removed. Contamination of the
belt may result in premature belt failure.
N0TE:Providing the coolant has not been
contaminated with other fluids or foreign matter,
the robust corrosion resistance properties of this
