J-39194-B Heated Oxygen Sensor Wrench

Caution: When replacing the HO2S perform the following:

Caution: Refer to Heated Oxygen and Oxygen Sensor Caution in the Preface section.

1. Remove the right front fender wheelhouse panel. Refer to Front Wheelhouse Liner Replacement.
2. Disconnect the heated oxygen sensor (HO2S) electrical connector (5) from the following:

•	The engine wiring harness electrical connector

•	The camshaft cover

Caution: Refer to Excessive Force and Oxygen Sensor Caution in the Preface section.




3. Using the J-39194-B wrench remove the HO2S from the exhaust manifold.

Note: Use special anti-seize compound on the HO2S threads. The compound consists of graphite suspended in fluid and glass beads. The graphite burns away, but the glass beads remain, making the sensor easier to remove. New service sensors already have the compound applied to the threads. If you remove an oxygen sensor and if for any reason you must install the same oxygen sensor, apply the anti-seize compound to the threads before reinstallation.

1. Coat the threads of the HO2S with the anti-seize compound P/N 5613695, or equivalent if necessary.

Caution: Refer to Component Fastener Tightening Caution in the Preface section.

2. Using the J-39194-B wrench , install the HO2S into the exhaust manifold and tighten to 42 N·m (31 lb ft).



3. Connect the HO2S electrical connector (5) to the following:

•	The engine wiring harness electrical connector

•	The camshaft cover

4. Install the right front fender wheelhouse panel. Refer to Front Wheelhouse Liner Replacement.
