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

1. Relieve the coolant system pressure.
2. Turn OFF the ignition.



3. Remove the ECT sensor electrical connector.



4. Remove the ECT sensor.

1. Only coat the threads with sealer P/N 9985253 or equivalent.



2. Install the ECT sensor.

Tighten
Tighten the sensor to 25 N·m (18.5 lb ft).

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.




3. Install the electrical connector.
4. Refill the lost coolant.
