ION L4-2.2L VIN F (2004)
IMPORTANT: A special anti-seize compound is used on the oxygen sensor 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 will have the compound
applied to the threads. If a sensor is removed and is to be reinstalled, the threads must have an anti-seize compound applied before installation.
NOTE: Refer to Fastener Notice in Service Precautions.
2. Install the oxygen sensor.
Tighten the oxygen sensor to 30 N.m (22 lb ft).
3. Connect the oxygen sensor harness connector.
4. Install the exhaust manifold heat shield.
