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. Partially drain the cooling system. Refer to Draining and Filling Cooling System (LS4 Static Fill) Draining and Filling Cooling System (L26, L32 Static Fill) Draining and Filling Cooling System (GE 47716 Fill) in Cooling System. See: Engine, Cooling and Exhaust Cooling System Service and Repair
2. Disconnect the ECT sensor electrical connector.

3. Remove the ECT sensor.

INSTALLATION PROCEDURE

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

1. Coat the threads with sealer GM P/N 12346004 (Canadian P/N 10953480) or equivalent.

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.

2. Install the ECT sensor.

NOTE: Refer to Fastener Notice in Service Precautions.

Tighten the ECT sensor to 25 N.M (18 lb ft).

3. Connect the ECT sensor electrical connector.
4. Fill the cooling system. Refer to Draining and Filling Cooling System (LS4 Static Fill) Draining and Filling Cooling System (L26, L32 Static Fill) Draining and Filling Cooling System (GE 47716 Fill) in Cooling System. See: Engine, Cooling and Exhaust Cooling System Service and Repair
