Removal Procedure
- Turn OFF the ignition.
- Raise the vehicle. Refer to Lifting and Jacking the Vehicle.
- Drain the engine coolant below the level of the engine coolant temperature (ECT) sensor. Refer to Cooling System Draining and Filling.
- Lower the vehicle.
- Disconnect the harness connector from the ECT sensor.
- Remove the ECT sensor.
Caution: Use care when handling the coolant sensor. Damage to the coolant sensor will affect the operation of the fuel control system.
Installation Procedure
- Coat the ECT sensor threads with sealer P/N 12346004 (Canadian P/N 10953480) or the equivalent.
- Install the ECT sensor and tighten to 20 N·m (15 lb ft).
- Connect the ECT sensor electrical connector.
- Refill the engine coolant. Refer to Cooling System Draining and Filling.
Caution: Replacement components must be the correct part number for the application. Components requiring the use of the thread locking compound, lubricants, corrosion inhibitors, or sealants are identified in the service procedure. Some replacement components may come with these coatings already applied. Do not use these coatings on components unless specified. These coatings can affect the final torque, which may affect the operation of the component. Use the correct torque specification when installing components in order to avoid damage.
Caution: Use care when handling the coolant sensor. Damage to the coolant sensor will affect the operation of the fuel control system.
Caution: Refer to Fastener Caution in the Preface section.
