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

existing coolant.
Fail-Safe Cooling
The vehicle has a strategy built into the powertrain
control module (PCM) that will control the engine
if the engine starts to overheat.
If the engine starts to overheat, stage
1 of the
strategy will commence. The ECT sensor transmits
a signal to the PCM which then moves the
temperature gauge pointer into the red zone.
If the engine is not switched off and the
temperature continues to rise, the malfunction
indicator lamp (MIL) is illuminated. This indicates
to the driver that the engine is approaching critical
limits and should stop. At this point DTC
PI285 is
set in the PCM which can be retrieved using WDS.
If the MIL and temperature gauge are ignored by
the driver, stage 2 of the strategy will commence.
The PCM will start to control the engine by cutting
out two cylinders and restricting the RPM to below
3000 RPM. The MIL will remain illuminated. This
indicates that long term engine damage may occur
and vehicle emissions will be affected. At this point
DTC
PI299 is set in the PCM which can be
retrieved using WDS.
Air is drawn into the deactivated cylinders which
helps to control the temperature of the engine
internal components. The deactivated cylinders
are alternated to allow even cooling of all the
cylinders.
N0TE:lf the driver is using a high percentage of
throttle travel (for example, an overtaking
maneuver) when the PCM starts engine
deactivation (stage 2), the deactivation will be
delayed for 10 seconds.
N0TE:After 2-cylinder operation has begun, the
engine will not revert to 4-cylinder operation, even
if the temperature should fall, until the ignition is
switched off and then on again.
N0TE:The MIL can only be extinguished by using
WDS after the fault has been rectified and the DTC
cleared.
