Removal Procedure
WARNING: This page is about a different variant/trim than selected.
WARNING:
In order to avoid being burned, do not service the exhaust system while it is still hot. Service the system when it is cool.
WARNING:
Avoid contact with HOT components. Wear safety glasses and protective gloves to avoid personal injury.
CAUTION:
Refer to Heated Oxygen and Oxygen Sensor Caution .
CAUTION:
The use of excessive force may damage the threads in the exhaust manifold/pipe.
NOTE:
- The heated oxygen sensor in-line connector and louvered end MUST be kept clear of all grease, dirt, and other contaminants. Do NOT use cleaning solvents of any type. Do NOT drop or roughly handle the sensor.
- The heated oxygen sensor MAY be difficult to remove when the engine temperature is less than 48°C (120°F).
- A special anti-seize compound is used on the heated oxygen sensor threads. The compound consists of 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 already 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. Adhesives, Fluids, Lubricants, and Sealers
