INSTALL a new coolant expansion tank cap.
5. Check the engine for coolant leaks. Drain the

REFER to: Cooling System Draining, Filling and
Bleeding (303-03 Engine Cooling
- 2.OL
Duratec-HE (M14), General Procedures).
.Recheck the system by repeating Steps 3 and
4 at least twice.
Radiator Leak Test, Removed From Vehicle
CAUTI0N:Radiator internal pressure must
not exceed
130 kpa (20 psi) or damage may
result.
Clean the radiator thoroughly before leak testing
it, to prevent contamination of the water in the test
tank. Leak test the radiator in clean water with 138
kpa (20 psi) air pressure. Check it thoroughly for
air leaks. INSTALL a new radiator if necessary.
REFER to: Radiator (303-03 Engine Cooling
- 2.OL
Duratec-HE (M14), Removal and Installation).
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.
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
I. Connect the WDS to the data link connector
(DLC).
2. Using the WDS datalogger function, SELECT
the following sensors (as applicable to the
application):
IAT
- intake air temperature (IAT) sensor
ECT
- engine coolant temperature (ECT) sensor
CHT
- cylinder head temperature (CHT) sensor
LOAD
- engine load
VSS
- vehicle speed sensor (VSS)
RPM
- engine speed
DSRPM
- desired engine speed
The IAT sensor output is useful if the engine being
tested is cold or after an over-night cold soak. The
ECT sensor or CHT sensor and the IAT sensor
(
should either indicate the same value or be within
1 to 2 degrees Celsius of each other.
The ECT sensor output is important to display as
it indicates the engine warm-up and opening
temperature for the thermostat. It will initially
indicate a slightly higher reading just before the
thermostat opens and then drops back before
settling to a near flat line output (see graphic
below).

303-03B-15 Engine Cooling - 2.OL Duratec-HE (M14) 303-03B-15
DIAGNOSIS AND TESTING
A CAUTI0N:lf the ECT sensor output reaches
the
120°C default line under normal cooling
system pressure, internal damage may be
caused to the engine and a diagnostic
trouble code (DTC) will be set in the PCM.
The test should be stopped and the cause
located and corrected. If the cooling
system does not pressurize, the coolant
will boil at
1 OO°C which may also damage
the engine. CARRY
OUT the Coolant
Expansion Tank Cap Pressure Test
Component Test in this section.
If the WDS only allows the ECT sensor to be
displayed in volts, refer to the following table for
corresponding Celsius values:
The CHT sensor output is useful to examine the
cylinder head temperature rise during the warm-up
cycle and later during the normal light throttle cruise
test. This sensor output may vary between vehicles
with manual transmission and vehicles with automatic transmission and should be used for
reference only.

0.78
0.60
0.46
0.35 0.27
The LOAD display is used for reference as it is
necessary to maintain a stable load line during the
test. It is necessary to carry out the test under
normal light throttle cruise driving conditions and
average loads, typically 40% to 70% of the load
value.

The VSS output is used for reference but can help
to identify misfires and sensors which fail during
the warm-up cycle.
The RPM display indicates the engine speed and
can be compared with the DSRPM.
The DSRPM is the desired or calculated idle speed
which the PCM commands the engine to reach. If
the thermostat opens too early (before the correct
opening temperature has been reached), the
engine will not reach this value. When
using the WDS in data logger mode, the
signals recorded should remain within the
DEFAULT values set by the WDS.
3m AWARNING:M~~~ sure that the WDS is
placed in the vehicle so that it does not
interfere with the safe operation of the
vehicle. Do not place the WDS in the
deployment path of any air bag. Failure to
follow these instructions may result in personal injury.
N0TE:The road test is best carried out with the
aid of another technician in the vehicle to enable
the vehicle to be driven safely while the sensor
outputs are monitored within datalogger. If there
is only one technician available, the WDS can be
set up (using the
recordlcapture mode camera
icon) before leaving the workshop to record a 16
km (1 0 mile) test.
N0TE:The results from the test are more
conclusive if the engine is cold when the test is
started.
Carry out a road test.
REFER to:
RoadIRoller 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
(88OC) and
fully open temperature (1
02OC) of a thermostat.
The graphic below shows an alternative method used to show the opening temperature
(88OC) and
fully open temperature
(112OC) of a thermostat.
