ECT Sensor Removal and Installation
Removal
1) Lift and support the fuel tank. Refer to "Fuel Tank
Removal and Installation in Section 1G (Page 1G-
10)".
2) Drain engine coolant. Refer to "Cooling System
Inspection in Section 0B (Page 0B-13)".
3) Disconnect the coupler and remove the ECT sensor
(1).
CAUTION
!
Take special care when handling the ECT
sensor. It may cause damage if it gets an
excessive impact.

Installation
Install the ECT sensor in the reverse order of removal.
Pay attention to the following points:
• Tighten the ECT sensor (1) to the specified torque.
CAUTION
!
Use new gasket washer to prevent engine
coolant leakage.
Tightening torque
ECT sensor (a): 18 N·m (1.8 kgf-m, 13.0 lb-ft)
• Pour engine coolant. Refer to "Cooling System
Inspection in Section 0B (Page 0B-13)".

Engine Electrical Devices:
1) Remove the ECT sensor. Refer to "ECT Sensor
Removal and Installation (Page 1C-5)".
2) Connect the ECT sensor (1) to the circuit tester and
place it in the oil (2) contained in a pan, which is
placed on a stove.
3) Heat the oil to raise its temperature slowly and read
the column thermometer (3) and ohmmeter.
If the ECT sensor ohmic value does not change in
the proportion indicated, replace it with a new one.
CAUTION
!
• Take special care when handling the ECT
sensor. It may cause damage if it gets an
excessive sharp impact.
• Do not contact the ECT sensor and column
thermometer with a pan.
