Removal Tool
^ When removing a seized exhaust sensor with a specialty socket (which contains a slit to accommodate the wiring harness), it may spread open and
strip the sensor.
^ Before this occurs, it is recommended to cut the wiring harness from the sensor and use a box end wrench or 6-point deep well socket.
1. Clamp the exhaust manifold/catalyst/front tube in a vice.
2. Spray the sensor with the rust penetrant for 2 to 3 seconds.
^ It is important that the spray is directed at the base of the sensor to ensure it penetrates into the threads.
