CHT sensor is used on all engines excluding the 4.0L V6 engines of some models. For 3.7L V6 engines, the sensor is located, and needs access near the front of the engine beneath the intake manifold. For 4.6L V8, it is located on the right side on the cylinder head or under the intake manifold where the sensor has to be unbolted to get at. for 5.0 L V8 engines, such a sensor is installed at the back of one of the right cylinders, and it is pointed upwards toward the opposite cylinder. It is possible to start by removing an end of the cable and then separating it from the negative terminal of the battery. For 3.7L V6 or 4.6L V8 engines, if necessary, remove the intake manifold. Following this, remove the electrical connection to the CHT sensor; to have the sensor removed from the head, the electrical connection has to be disconnected then the CHT sensor unscrewed. For the previous year models, the manufacturer warned that if the CHT sensor is removed, another new one should be fitted to it. Lastly, disconnect the CHT sensor by unscrewing it and then, the installation should be done in the reverse manner with the right tightening of the sensor to the right torque.
