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 or service sensors already have the compound applied to the threads. If you remove an oxygen sensor and if for any reason you must reinstall the same oxygen sensor, apply the anti-seize compound to the threads before reinstallation.

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

CAUTION:

Refer to Fastener Caution .

Install the HO2S (1) and tighten to 41 N.m (30 lb ft).
Install the right side catalytic converter. Refer to Catalytic Converter Replacement - Right Side .
Connect the HO2S electrical connector. Ensure that the harness is routed and retained as noted during disassembly.
Lower the vehicle.
