Engine - Oil Leaks
NOTE: Before installing new gaskets or seals, make
sure that the fault is clearly established.
If the oil leak cannot be identified clearly by a visual
inspection, carry out an ultraviolet
(UV) test:
Ultraviolet (UV) Testing
1. Clean the engine and transmission with a
suitable cleaning fluid.
2. Pour the UV-test fluid in accordance with the
quantity specified by the manufacturer through
the oil filler neck into the engine and install the
oil filler cap.
A WARN1NG:Vehicles with manual transaxle,
shift the transaxle into Neutral. Failure to
follow this instruction may result in
personal injury.
3. Start the engine and let it run for about five
minutes. 4.
Switch off the engine.
N0TE:lf no leak can be found, road test the vehicle
under various loads and check the engine for leaks
again.
5. Check the engine for oil leaks using a suitable
UV lamp.
'
6. Rectify any leaks found and check the engine
for oil leaks.
Measure the compression pressure
N0TE:The powertrain control module (PCM)
receives an error message when the fuel pump
relay is removed or electrical components are
disconnected. This error message must be deleted
from the fault memory using WDS after completing
the compression test.
(' ,
'I N0TE:Valve clearance must be set correctly before
performing a compression test. Make sure the
engine is at the normal operating temperature.

DIAGNOSIS AND TESTING
RPM - engine speed
i 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).
Item Description
I A I Thermostat opens I
B Thermostat settles into a cyclic open and
I I closure pattern
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
100°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:
Volts
OCelsius
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.

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.

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.

example of the opening temperature
(88OC) and
fully open temperature (1
