Carry out a road test. The
engine should start cleanly and the ECT value
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
(88OC) and
fully open temperature (1
02OC) of a thermostat. will
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.
