Engine Coolant Temperature Sensor: Installation
WARNING: This page is about a different car, the 2003 Chevrolet Corvette. However, it is still accessible from the selected car via links, so may be relevant.
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.
Coat the ECT sensor threads with Sealer (12346004) or the equivalent. Install the ECT sensor. See Fig 2. Tighten the ECT sensor to specification. See TORQUE SPECIFICATIONS . Connect the ECT sensor electrical connector. Refill and bleed the engine coolant system. See COOLING SYSTEM BLEEDING under COOLING SYSTEM.
