Notice: Allow sufficient time for the engine to cool before removing the ECT sensor. Excessive coolant loss or personal injury may result if the engine is hot.

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

1. Partially drain the coolant system.



2. Disconnect the ECT sensor connector.
3. Remove the ECT sensor.

Notice: A non-hardening sealer should be applied to the sensor threads prior to installation to prevent coolant leaks. Use P/N 1050805 or equivalent.

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 ECT sensor.

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

2. Connect the ECT sensor connector.
