Q:How do I install an O2 Sensor on my 98 Jeep Cherokee Sport? It has the 4L engine.
A:The oxygen sensor is located just below the junction of the exhaust manifold and the exhaust pipe, the heat from running the engine will make the exhaust expand, and the sensor will be easier to unscrew. Lift the vehicle with a jack and secure it on jack stands. Put on gloves then disconnect the electrical connection to the sensor by pulling it loose. Do not pull it by the wires. Pull only on the body of the connector. Remove the sensor by turning it in a counterclockwise direction with the appropriate-sized wrench. Examine the threads of the new oxygen sensor to see if they are already coated with anti-seize compound. If they are not, coat them with a light layer. Some sensors are coated by the manufacturer while others are not. Install the new sensor by turning it in a clockwise direction with the wrench. Reattach the electrical connector. Raise the vehicle with the jack and remove the jack stands. Carefully lower the vehicle.
