Oxygen Sensors: Installation
WARNING: This page is about a different car, the 2002 Oldsmobile Bravada, 2002 GMC Envoy XL, 2002 GMC Envoy, and 2002 Chevrolet TrailBlazer. However, it is still accessible from the selected car via links, so may be relevant.
CAUTION:
Correct tightening of oxygen sensor is critical to prevent crushing glass beads in graphite anti-seize compound. Crushing glass beads will cause sensor to seize in exhaust manifold. This may necessitate repair or replacement of exhaust manifold upon next removal.
- Whenever oxygen sensor is removed, coat threads with Anti-Seize Compound (5613695) before reinstallation. New oxygen sensors already have this compound applied to threads.
- Install oxygen sensor into exhaust manifold. Tighten oxygen sensor to specification. See TORQUE SPECIFICATIONS . Reconnect harness connector to oxygen sensor.
