WARNING: This page is about a different variant/trim than selected.
IMPORTANT:
A special anti-seize compound is used on the HO2S threads. The compound consists of a liquid graphite and glass beads. The graphite will burn away but the glass beads will remain, making the sensor easier to remove. New or service sensors already have the compound applied to the threads. If the sensor is removed and is to be reinstalled, the threads must be coated with an anti-seize compound before reinstallation.
- If reinstalling the old HO2S, coat the threads with anti-seize compound, Saturn P/N 24185279, or equivalent.
- Carefully install the HO2S to the pipe.
- Using the J 39194
, or equivalent, tighten the HO2S.
Tighten: Tighten the HO2S to 41 N.m (30 lb ft).
- Install the HO2S electrical harness into position as noted before removal.

Refer to Component Fastener Tightening Notice
