ECT SENSOR INSPECTION
Remove the ECT sensor (page 5-63).
Heat the coolant (1:1 mixture) with an electric heat-
ing element.
Suspend the ECT sensor in heated coolant and
check the continuity through the sensor as the cool-
ant heats up.
• Soak the ECT sensor in coolant up to its threads
with at least 40 mm (1.6 in) from the bottom of
the pan to the bottom of the ECT sensor.
• Keep temperature constant for 3 minutes before
testing. A sudden change of temperature will
result in incorrect readings. Do not let the ther-
mometer or ECT sensor touch the pan.
Replace the ECT senor if it is out of specification by
more than 10% at any temperature listed.
Install the ECT sensor (page 5-63).
