Pressure Test
A WARNING: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.
N0TE:lf the coolant expansion tank cap is rotated
counterclockwise by 1 12 a full turn, the pressurized
coolant will be vented to the underside of the
coolant expansion tank cap.
1. Remove the coolant expansion tank cap.
2. Install the special tools 303-396 and 303-396-01
to the coolant expansion tank.
3. Pressurize the system to the coolant expansion
tank cap release pressure.

DIAGNOSIS AND TESTING
4. Observe the cooling system pressure tester make sure the pressure test reading
is

and within acceptable gauge reading
The pressure should not drop during this time. limits of
the coolant expansion tank cap.
( If the system holds Pressure, proceed to Step 5. If the pressure test gauge readings are not 7. If the system does not hold pressure, check
within the acceptable gauge reading limits,
it thoroughly for coolant leaks.
INSTALL a new coolant expansion tank cap.
5. Check the engine for coolant leaks. Drain the
cooling system, repair any coolant leaks found
and fill and bleed the cooling system as

necessaw.
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.

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).

The PCV valve is located on the upper side of the
cylinder head cover.
The crankcase gases are sucked by the PCV valve
into the intake manifold.
The PCV valve is opened by the vacuum in the
intake manifold.
The amount of crankcase gases depends on the
engine speed. The quantity sucked in is determined
by the spring and the shape of the piston. The deflection plate
is integrated into the cylinder
head cover.
It prevents oil from being sucked in and burned in
the combustion process.
The oil drops condense on the deflection plate and
are then returned to the oil circuit.
