INSPECTION
Remove the ECT sensor (page 6-74).
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 (1.57 in) from the bottom of
the pan to the bottom of the switch.
• 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 sensor if it is out of specifications.

sealing washer with
a new one.

(page 7-6).
