Coolant Temperature Sensor/Switch (For Computer): Service and Repair

ENGINE COOLANT TEMPERATURE (ECT) SENSOR REPLACEMENT

REMOVAL PROCEDURE

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




1. Drain the coolant system to below the engine coolant temperature (ECT) sensor. Refer to Draining and Filling Cooling System (Static Fill) Draining and Filling Cooling System (GE 47716 Fill). Service and Repair
2. If equipped with a automatic transaxle, disconnect the engine coolant temperature (ECT) sensor electrical connector (1).




3. If equipped with a manual transaxle, disconnect the ECT sensor electrical connector (1).




4. Remove the ECT sensor.

INSTALLATION PROCEDURE

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




1. Install the ECT sensor.

NOTE: Refer to Fastener Notice in Service Precautions.

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




2. If equipped with a manual transaxle, connect the ECT sensor electrical connector (1).




3. If equipped with a automatic transaxle, connect the ECT sensor electrical connector (1).
4. Fill the cooling system. Refer to Draining and Filling Cooling System (Static Fill) Draining and Filling Cooling System (GE 47716 Fill). Service and Repair
