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 battery negative cable.
2. Disconnect the harness connector from the coolant temperature sensor.



3. Remove the coolant temperature sensor (1).
4. Drain the engine coolant into a suitable container as necessary. Refer to Cooling System Draining and Filling

Notice: Use the correct fastener in the correct location. Replacement fasteners must be the correct part number for that application. Fasteners requiring replacement or fasteners requiring the use of thread locking compound or sealant are identified in the service procedure. Do not use paints, lubricants, or corrosion inhibitors on fasteners or fastener joint surfaces unless specified. These coatings affect fastener torque and joint clamping force and may damage the fastener. Use the correct tightening sequence and specifications when installing fasteners in order to avoid damage to parts and systems.

1. Install the coolant sensor to the engine (1).

Tighten
Tighten the coolant sensor (1) to 20 N·m (15 lb ft).




2. Install the harness connector.
3. Check the engine coolant level.
4. Refill the engine coolant as necessary. Refer to Cooling System Draining and Filling

Notice: Use the correct fastener in the correct location. Replacement fasteners must be the correct part number for that application. Fasteners requiring replacement or fasteners requiring the use of thread locking compound or sealant are identified in the service procedure.

5. Connect the battery negative cable to the negative battery terminal.

Tighten
Tighten the battery negative cable bolt to 15 N·m (11 lb ft).
