ECT SENSOR INSPECTION

Remove the ECT sensor (page 5-63).

Wear insulated gloves and adequate eye protection.

Keep flammable materials away from the burner.

Heat the coolant (1:1 mixture) with an electric heating element.

Suspend the ECT sensor in heated coolant and check the continuity through the sensor as the coolant 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 thermometer or ECT sensor touch the pan.
