Monte Carlo V6-3.5L VIN K Flex Fuel (2006)
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 cooling system. Refer to Draining and Filling Cooling System (LS4 Static Fill) Draining and Filling Cooling System (LZE, LZ4, LZ9
Static Fill) Draining and Filling Cooling System (9C1, 9C3 Static Fill) Draining and Filling Cooling System (LS4 GE 47716 Fill) Draining and
Filling Cooling System (LZE, LZ4, LZ9, 9C1, 9C3 GE 4771 Fill). See: Engine, Cooling and Exhaust/Cooling System/Service and Repair
2. Remove the intake manifold cover, if necessary.
3. Disconnect the engine coolant temperature (ECT) sensor electrical connector.
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.
