Notice: Use care when handling the coolant sensor. Damage to the coolant sensor will affect the operation of the fuel control system.

Caution: Unless directed otherwise, the ignition and start switch must be in the OFF or LOCK position, and all electrical loads must be OFF before servicing any electrical component. Disconnect the negative battery cable to prevent an electrical spark should a tool or equipment come in contact with an exposed electrical terminal. Failure to follow these precautions may result in personal injury and/or damage to the vehicle or its components.

1. Disconnect the negative battery cable.



2. Loosen the wing nuts on the air cleaner cover and on the air cleaner outlet duct.
3. Move the air intake assembly aside.

Caution: Allow sufficient time for the engine to cool before removing the ECT sensor. A hot engine may cause an excessive coolant loss or a personal injury.

4. Relieve the coolant pressure.
5. Drain the cooling system below the level of the sensor. Refer to Cooling System Draining and Filling in Engine Cooling.



6. Disconnect the ECT sensor harness connector.



7. Remove the ECT sensor.

1. Coat the threads with a sealant.




Notice: 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.

2. Install the ECT sensor in the engine.

Tighten
Tighten the sensor to 20 N·m (15 lb ft).




3. Connect the ECT sensor harness connector.
4. Refill the cooling system. Refer to Cooling System Draining and Filling in Engine Cooling.



5. Install the air intake assembly, and tighten the wing nuts.
6. Connect the negative battery cable.
