OXYGEN SENSOR REMOVAL CAUTION
BULLETIN NOTE This bulletin supersedes previous bulletin 01-019/07 issued on 05/10/07. The APPLICABLE MODEL(S)/VIN and REPAIR PROCEDURE has been revised.
APPLICABLE MODEL(S)/VINs
DESCRIPTION
Use caution when removing oxygen sensors, otherwise the tip of the sensor may break off, which will be difficult to remove. In the worst case, both oxygen sensor and catalyst converter/exhaust pipe will need to be replaced.
Repair Procedure
Oxygen Sensor Removal Procedure
WARNING: To avoid personal injury, allow exhaust system to cool down before removing oxygen sensor.
1. If reusing oxygen sensor, mask it with masking tape to prevent lubrication soaking.
2. Spray CRC Freeze-Off (or equivalent) around flange area of oxygen sensor.
CAUTION: Avoid excess spraying. Remaining flammable substance could catch fire.
3. Allow lubricant to reach sensor threads for a minimum of 1 - 2 minutes.
NOTE: FOLLOW ALL PENETRANT MANUFACTURER INSTRUCTIONS LISTED ON THE PRODUCT LABEL.
4. Wipe off all excess lubricant.
5. Use SST 49 L018 001 to loosen sensor.
NOTE: If sensor begins to bind, it may be necessary to work the sensor in a tightening and loosening motion to slowly work the sensor out.
6. Clean 02 sensor threads in converter or pipe with an 18 mm x 1.5 mm tap.
7. Coat 02 sensor threads with "NEVER-SEEZ" (or equivalent) high temperature nickel based anti-seize grease.
WARNING: If reusing the oxygen sensor, completely remove the masking tape to prevent vehicle fire.
8. Install 02 sensor and tighten to:
Tightening Toque: 29 - 49 Nm (22 - 36 ft. lbs.)
