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.
Fig. Removing engine coolant temperature sensor
Partially drain the engine coolant below the level of the Engine Coolant Temperature (ECT) sensor.
Disconnect the ECT sensor electrical connector (1) from the engine wiring harness and the camshaft cover.
Using sensor socket (2) J-45861, carefully remove the ECT sensor from the cylinder head.
To install, reverse the removal procedure. Tighten the sensor to 124 inch lbs. (14 Nm). Refill the engine coolant.
