Installation Procedure

WARNING: This page is about a different car, the 2005 Chevrolet Corvette. However, it is still accessible from the selected car via links, so may be relevant.

IMPORTANT: Use special anti-seize compound on the heated oxygen sensor 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.
