ENGINE COOLANT TEMPERATURE (ECT) SENSOR REPLACEMENT
NOTE: Use care when handling the coolant sensor. Damage to the coolant sensor will affect the operation of the fuel control system.
1. Turn the engine OFF.
2. Disconnect the negative battery terminal. CAUTION: Refer to Battery Disconnect Caution in Service Precautions.
3. Drain coolant below the level of the ECT sensor. Refer to Draining and Filling Cooling System (Body Vin Code 6)Draining and Filling Cooling System (Body Vin Code 3) in Cooling System.
4. Disconnect the ECT sensor electrical connector (1).
5. Remove the drive belt and the generator.
6. Carefully remove the ECT sensor (1).
*Use care when handling the coolant sensor. Damage to the coolant sensor will affect the operation of the fuel control system.
*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.
1. If installing the original sensor or a new sensor without sealant, apply thread sealer P/N 12346004 or equivalent.
2. Install the ECT sensor. NOTE: Refer to Fastener Notice in Service Precautions. Tighten Tighten the ECT sensor to 16 N.M (12 lb ft).
3. Connect the ECT electrical connector (1).
4. Install the generator and the drive belt.
5. Connect the negative battery terminal.
6. Refill the engine coolant. Refer to Draining and Filling Cooling System (Body Vin Code 6)Draining and Filling Cooling System (Body Vin Code 3) in Cooling System.
