Oxygen Sensors: Installation
WARNING: This page is about a different car, the 2002 GMC Sierra, 2002 GMC Cab & Chassis Sierra, 2002 Chevrolet Silverado, and 2002 Chevrolet Cab & Chassis Silverado. 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 pipe. This may necessitate repair or replacement of exhaust pipe 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 pipe using Oxygen Sensor Tool (J-39194-B). Tighten oxygen sensor to specification. See TORQUE SPECIFICATIONS . Reconnect harness connector to oxygen sensor. Lower vehicle. Test system.
