Installation Procedure

    NOTE:

    A special anti-seize compound is used in the sensor or line fittings threads. The compound consists of liquid graphite and glass beads. The graphite tends to burn away, but the glass beads remain, making the sensor or line fitting easier to remove. New, or service replacement sensors or line fittings already have the compound applied to the threads. If the sensor or line fittings are removed from an exhaust component and if for any reason the sensor or line fitting are reinstalled, the threads must have anti-seize compound applied before reinstallation.

  1. If reinstalling the old sensor pipe or sensor line fittings, coat the threads with anti-seize compound. Adhesives, Fluids, Lubricants, and Sealers
