2.0L Engines




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

  1. Turn OFF the ignition.
  2.  
  3. Drain the coolant system to below the Engine Coolant Temperature (ECT) sensor.
  4.  
  5. Disconnect the ECT sensor electrical connector.
  6.  
  7. Carefully remove the ECT sensor.

NOTE
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.


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

  1. If you are reinstalling the original sensor, or if you are installing a new sensor without a sealer, coat the threads with sealer Saturn P/N 21485278, or an equivalent.
  2.  
  3. Install the ECT sensor, and tighten the ECT sensor to 16 ft. lbs. (22 Nm).
  4.  
  5. Connect the ECT sensor electrical connector.
  6.  
  7. Refill the engine coolant system.
